Description

1296532 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a liquid atomization process and a technical component designed for liquid atomization, such as a sprayer. In particular, the present invention can be used as part of an automatic fire suppression system for extinguishing fires with many possible fire points in rooms such as hospitals, libraries, museums, office buildings, warehouses, garages, and the like. [Prior Art] A variety of methods for generating an atomized liquid stream are currently known. For example, German Patent No. 10010881 (issued by IPC A62C 37/00, issued Jun. 2001.13) describes a method of producing a flow of atomized liquid comprising supplying the liquid under pressure into an axial passage of a liquid atomizer. The liquid stream is split into two streams by a dividing wall installed in the axial passage of the atomizer. A liquid flow symmetrically planar to one of the dividing walls is formed in the flow passage. The tangential supply of liquid into the flow channels promotes turbulent flow of liquid in the opposite direction within the flow channel. The liquid produced in the flow passage provided in a chamber at the outlet of the flow passage is mixed to produce a turbulent liquid flow. The synthetic full-flooding liquid stream produced within the chamber is atomized via an outlet opening of the sprinkler channel. The prior art method and apparatus allow for the production of a conical atomized liquid stream having a wide range of taper and allows for varying droplet sizes. By varying the outlet opening portion, one of the liquids in the nebulizer can be supplied with a constant pressure regulating gas and droplet ejection stream parameters. The liquid stream can be further turbulent by using a shaped baffle disposed opposite the outlet opening. It should be noted that the prior art 101695.doc 1296532 device is not equipped with a starter-atomizer hot door and the liquid is supplied to the atomizer. The response unit automatically opens when installed in the -main line, when the predetermined ambient temperature is reached, in the automatic fire extinguishing system

Liquid atomization can be performed using a sprinkler with a single-acting valve equipped with a thermal response unit.

The "out" of the axial passage is in communication with the four flow passages. - the thermal response unit is fixed to the sprinkler housing by means of an attachment

^ - Partial (four) is connected to the - valve 'The 阙 (10) closes the cylindrical axial liquid supply channel - the population opening. The valve can be maintained in the initial position together with the deflector by means of a _configured-horizontal positioning thermal response unit of the temperature measuring ball. The outlet openings of the flow channels are all distributed around the circumference of the end surface of the sprayer housing. The axis of symmetry of the flow channels is set at an angle to the axis of symmetry of the axial liquid supply channel. A vortex generating chamber is disposed in the center of the sprinkler housing. + Use - This prior art sprinkler produces an atomized jet with large droplets to increase fire suppression efficiency and reduce liquid consumption. However, since the liquid 2 is atomized toward the structural component of the attached fitting, a shadowing effect is generated in the process of dispensing the atomized liquid jet, and the non-uniform distribution of the above-mentioned four-in-one (four) drop jet is generated. A sprinkler and method for producing an atomized liquid jet is known from the 'state patent 0701842 (IPC A62C 37/08, issued 1996.03.20). The sprinkler includes a housing having a cylindrical axial passage, a housing including a 101695.doc 296532 thermal response unit, and a thermal response unit including a truss arm. The 畲 reaches - the predetermined ambient temperature and the thermal response unit is hit (4), and the liquid will be supplied to the axial passage of the sprinkler under a pressure. According to the prior art, the liquid flow can be split into two coaxial flows by means of a circular split partition wall mounted in the axial passage of the sprinkler. In the spiral flow channel disposed on the second side of the partition wall, a liquid flow of __ outside is generated. A central axial flow of fluid is created within the internal axial passage of the dividing wall. And so

The resultant stream is sent to a vortex chamber located upstream of the axial passage of the sprayer outlet opening. "Hai 疋 method and (4) permit the production of finely dispersible atomized liquid jets. These jets have an optimum droplet size suitable for fire suppression and provide rapid and fire extinguishing for a fire scene. However, prior art The sprinkler structure is incapable of producing a spatially uniform atomized liquid jet. The engagement of the atomized liquid stream with the components of the thermal response unit attachment assembly will result in a shadow that contributes to the non-uniformity of the atomized liquid distribution. Effect: A portion of the liquid flow exiting the axial passage opening changes its orientation after contacting the frame arm of the thermal response unit attachment. A plurality of low spray intensities are produced in the area shielded by the frame arms of the attached fitting. The area, and the area where the sprinkling intensity is increased at the joint boundary of the dedicated split flow in a free space. Therefore, it is impossible to provide uniform fire extinguishing to a large area of the fire scene. The closest to the patented method A similar method is a method of generating an atomized liquid jet as described in U.S. Patent No. 6,073,700 (issued to IPC A62C39/00, issued Jun. 2000. The activation of one of the unit's heat-sensitive components at a pre-clamping ambient temperature in 101695.doc 1296532 results in a liquid supply valve being opened to supply liquid into one of the cylindrical axial passages of the τ 丽. Accordingly, with the valve The liquid flow deflector mounted on the same rod is displaced to its lower operating position. The liquid is fed into the axial passage of the sprinkler at a predetermined pressure and is separated therein by means of an axial passage mounted in the sprinkler The wall is divided into two separate streams. A liquid flow symmetrical to one of the symmetrical planes of the dividing wall is formed in the curved opening. The liquid stream thus formed is supplied to one of the sprinklers Φ Converging axial channels The outlet opening is atomized in the surrounding space due to the engagement of the flow with the deflector plate. This will result in a finely dispersed atomized liquid jet. It should be noted that one of the important components of the sprinkler structure is used for The attachment member of the deflector plate and the thermal response unit includes a frame arm fixed to the sprinkler housing. Therefore, after the liquid is atomized in a space region in which the attachment member frame arm is placed, the liquid The body flow partially penetrates the sprinkler structure assembly. As a result, regions having different atomization intensities and thus different spray strengths to a surface to be protected are produced. The closest device to the claimed patented device A sprinkler disclosed in the above-mentioned U.S. Patent No. 6,073,700. The prior art sprinkler includes a housing having a cylindrical axial liquid supply passage, wherein an eight partition wall is mounted to divide the axial passage into two a curved flow passage symmetrical with one of the partition walls. The heat-responsive unit and a liquid flow deflecting plate are separated by an attachment fitting in the lower portion of the sprinkler. The thermal response unit is composed of two heats. The first mechanism comprises an I-valve connected and assembled by a shape memory alloy. A thermal ^ 101695.doc 1296532 plastic \: externally formed in the τ portion and connected to the - liquid supply valve . The first heat-sensitive mechanism of the unit, the 曰' unit is located at the outlet opening of the axial passage to maintain the partition wall at its upper portion 4. The second thermal mechanism of the haihai package: t a plurality of plates held by components made of fusible alloy.

When the field coil is fired, the heat-sensitive element made of the shape memory alloy is added to the shape and the temperature is restored. The heat-sensitive assembly is elongated in a vertical direction to maintain the valve in its closed position. An increase in the air spill around the sprinkler causes the assembly of the fusible alloy to melt. As a result, the support plate is separated from the sprinkler to cause the deflector to move to its lower operating position. At the same time, the liquid supply valve opens to liquid Served into the cylindrical axial passage of the sprinkler. The method for producing an atomized liquid jet according to the above-mentioned U.S. Patent No. 6, 〇7 3 7 可 can achieve the operation of the sprinkler and generate fog. Liquid jet flow. It should be noted that one of the essential features of the method and apparatus is limited by the penetration of the liquid non-uniform spray on the protected surface due to the penetration between the liquid AIL and the accessory component. The object of the invention to be patented is to solve a problem associated with the elimination of the effect of the component structure on the spatial distribution of droplets within an atomized liquid jet produced. Technical Tasks The technical results achieved include the production of finely dispersed gases and droplet jets with a uniform spatial distribution of high kinetic energy droplets and droplets, which is of particular importance for effective fire scenes. The method for producing an atomized liquid jet by the implementation of a method is described in the following: 10: 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The spray-assisted ampoule further comprises: by cutting into two streams, and one of the dividing walls of the second channel divides the liquid flow into a plane, and forms a symmetrical ten-sided symmetry in the partition wall. Multiple liquid streams.兮笙# $ a 7蚺 Engaged and atomized, liquid flow by means of - deflector

The ^^ ^ ^ μ deflection plate is attached to the squirt housing by means of the yoke for the yoke and the shovel. The accessory accessory includes a number of frame arms. According to the present invention, the liquid flow is generated in the flow passage for bypassing, and the frame and the frame arm for the attachment member of the thermal response unit are positioned to be mounted thereon. In a plane of symmetry of the dividing wall in the axial passage. In this arrangement of frame arms, a flow of water is produced at the axial passage = outlet of the lance to bypass the frame arms for the deflector and the attachment for the thermal response unit. The relative arrangement of the frame arms and flow channel outlets of the 4 fittings reduces the kinetic energy loss that typically occurs when the liquid flow intersects the obstacle (in certain instances, the frame arm of the attachment). In order to provide a mode that is most suitable for enabling liquid flow to bypass the frame arm and is therefore most suitable for improving the uniformity of droplet distribution within the atomized liquid jet, various conditions need to be created to have a region near the outlet opening. A liquid flow is created in the flow channel configured as a cross section of a ring segment. The liquid stream formed by the flow channels has a plurality of central regions in which the liquid flows parallel to a plane of symmetry of the dividing wall. This 101695.doc 11 1296532 flow causes a uniform liquid film to be produced and effectively deflects the liquid stream as it is engaged with the deflector. In order to produce a gas with high kinetic energy droplets - the finely dispersed gas and the droplet jet stream 'in the flow channel having a length selected according to 4Du 〇D conditions [the liquid flow is formed, wherein (4) - Cut to the largest diameter of the ring in the exit portion of one of the flow channels. The m filaments of the flow channels are selected according to the φ condition which provides a steady flow of liquid. The length L of the flow channels greater than i 〇 d causes an increase in the loss of liquid kinetic energy due to friction between the liquid flow and the surface of the flow passage. The length L of the flow channels less than 4D may cause the liquid flow (4) to deviate from the direction of ensuring the maximum uniform spatial distribution of the liquid to be atomized. To increase the droplet velocity and the uniformity of the droplet space distribution within the atomized jet, a liquid stream is created in the flow channel that converges during the flow of the liquid. To prevent solid contaminants from obstructing the flow passage, the liquid flow through the axial passage of the sprinkler must be filtered after being supplied through the flow passages. • The liquid stream produced by atomization of the deflector plate having a flat continuous central portion is preferably confined within the geometrical boundary of the projecting portion of the cylindrical axial passage. In addition, the edge of the deflector plate can be formed into a matte shape and can be configured as a tapered surface capable of dispersing the flow of liquid during the flow of the liquid. The use of the above embodiments of the deflector plate to atomize the liquid allows the spray area to be increased with a predetermined uniformity, dispersibility and strength of a gas and droplet jet. The above technical results can also be achieved by using a sprinkler, which includes a housing of a cylindrical axial liquid supply passage, installed in the liquid supply passage of the liquid 101695.doc -12-1296532 a partition wall to divide the shaft, the flow passage channel symmetric to the -symmetric plane of the partition wall into two thermal response units; - a liquid flow deflecting plate; and including a valve and for deflecting comprising a plurality of frame arms The board is attached to the 5 Hz thermal response unit, and is used for the thermal response unit and the attachment for the deflection plate. The frame according to the present arm is positioned in the axial passage.

In the plane of the two flow channels 3 in the region of its outlet opening. Close can be configured as a - ring segment. The mother-to-segment cross-section selects the length of the flow channels according to the gamma (four) D condition, wherein the D-system is inscribed in one of the flow channels and the ring in the section of the port is the widest to achieve the established conditions. The liquid can be steadily flowed through the flow channel with minimal kinetic energy frictional losses. To increase the flow rate of the liquid, the flow channel can be concentrated during the flow of the liquid. In order to provide a converging shape of one of the flow passages, it is preferred to use a partition wall which disperses the liquid during the flow of the liquid. The optimum velocity of the liquid stream sufficient to satisfy a most efficient atomized liquid stream through the flow channels can be achieved by providing a dividing wall that disperses the liquid during the liquid flow with a 3-25% gradient. In this case, a gas having a fine dispersion of one of the high kinetic energy droplets and a droplet discharge stream can be produced. In the case where the partition wall gradient is less than 3%, it is noted that the liquid flow velocity is not substantially increased at the outlet of the flow passage. In the case where the gradient of the partition wall is greater than 25%, the kinetic energy loss of the liquid flow flowing through the flow passage increases. The 5H partition wall can be mounted in a certain core sleeve that is fixed in the cylindrical axial passage. In this case, a precise positioning of one of the divided partition walls can be achieved to achieve a maximum uniform distribution of liquid flow in the flow passage relative to one of the planes of symmetry of the partition wall by 101695.doc 13 1296532. In one embodiment of the "Haispray", the width of the frame arms adjacent to their attachment points to the outer casing should not exceed the width of the partition opening adjacent the outlet openings of the flow channels. The established structural embodiment allows The kinetic energy loss of the liquid stream is reduced to a greater extent and the uniformity of droplet distribution within the atomized jet is increased. This will result in the elimination of the possibility of changing the flow path of the liquid stream, which is due to the bypass of the liquid stream. On the surface of the frame of the thermal response unit and the attachment for the deflection plate. A filter having a maximum pore diameter equal to or less than 0.8D can be installed upstream of the sprinkler entering the inlet of the flow channel. The cylindrical axial passage. The use of the filter within the sprinkler structure prevents the flow passage from being obstructed thereby enhancing the reliability of the sprinkler operation. To increase the spray area, the liquid flow deflector may have a certain location A flat continuous center portion within the geometrical boundary of one of the cylindrical axial passages. With respect to this embodiment of the sprinkler, it is desirable that the deflector is The diameter of the portion exceeds the diameter of the axial passage by no more than two times. This limitation is given because the sprayer may immediately reduce the area to be sprayed when the diameter of the center portion of the deflector plate is significantly increased. In the preferred embodiment of the present invention, the edge of the liquid flow deflecting plate is made porous and formed into a tapered surface shape for dispersing the liquid during the flow of the liquid. It can be from about 10 to Selecting an angle of inclination of the conical surface mother point to a plane perpendicular to the axis of symmetry of the axial channel within a range of about 30. The established version of the nozzle sprinkler embodiment will ensure an increase in the large spray area 1 〇1695.d〇c -14· 1296532 distributes the uniformity of a finely dispersed gas and droplet jet. The right tilt angle is greater than 30. This will cause the liquid flow and deflection to result in the arm, two #士^ The surface of the iL1 is separated from the peripheral area and the intensity of the nozzle is increased compared to the surrounding & the axial component of the inclined surface of the tapered surface is reduced to a zero value and the central area is caused. ;= Degree is reduced. < Li Qiang Embodiments The sprinkler includes a casing 1 having an outer surface on its outer surface and a field sprayer coupled to a liquid portion for use in a thread for a boring tool (not shown). The cylindrical axial liquid partition wall 3 in which a partition wall 3 is installed is suitable for dividing the inner channel, the g, the ruthenium, the gold iridium, the w channel 2 〇f+r... the axial channel 2 into symmetry and separation. The flow channel 4 is enclosed in a core sleeve 5 located in the axial passage. In the type of embodiment of the invention considered, the partition wall 3 is made to be the best ladder from 3% to 25%. One step: the gradient disperses the liquid during the circulation process, and the flow channel defined by the partition surface and the 疋~ sleeve 5 can be in a liquid flow process: the body conforms to the shape of the partition wall 3.

In the present invention, the flow channel 4 L is 6D to conform to the length of the selected stream. Condition of length: The filter 6 located in the axial passage 2 101695.doc -15-1296532 of the outer casing entering the inlet of the flow passage 4 can be configured as a cylindrical porous insert, wherein the insert has an aperture of 7 In order to meet the patent application range according to the present invention, the condition of the maximum size of the extruder is selected: not more than 〇.8〇. A valve 8 having a valve plug and made of a polymeric material is suitable for closing an outlet opening of the axial passage 2. One can be, 9 ... θ should be in the initial position (the thermal component glass ball head 9) _8S) in its initial position. The glass ball head 9 is filled with a liquid having a volume expansion which is sufficient to destroy the glass ball head due to liquid expansion when the ambient temperature reaches a predetermined π level. The thermal response unit having the glass ball head 9 and the liquid flow deflection (four) can be attached to the outer casing of the squirt by means of the attachment means for the thermal response unit and the deflector for the deflection plate. The attachment comprises: a holder U for attaching the deflection plate 10 and for holding the glass ball head 9 in its initial position, a frame arm 12 for engaging the holding wood 11 with the outer casing i, and for making the glass ball head 9 Keep it in its initial vertical position. The adjusting screw 13 is located in the axial opening of the holder 11. The frame arms 12 for the singular 70 and the attachment for the liquid flow deflection plate are all arranged in a plane of symmetry of the partition wall 3 of the axial passage 2 (see Figs. 1 and 3). The width of the frame arm of 6 hai and so on in the area to which it is attached to the outer casing ^ does not exceed the width Lpw of the knives in the plane of the outlet portion of the flow passage 4 (see Fig. 3). The liquid flow deflector plate has a flat continuous central portion 14. The central cutter 14 is located within the geometrical boundary of the extension of the axial passage 2. In the example of the sprinkler embodiment considered, one of the central portions 14 has a diameter of 101695.doc -16-1296532 DCP=I ·5〇(:Η, where Dch is the axial passage 2 of the sprinkler One of the diameters. According to the condition of selecting the optimum value of IWDW, the diameter ~ exceeds the diameter ~ not more than twice. The edge of the liquid flow deflection (4) located outside the geometrical boundary of one of the axial passages 2 is made porous and It is configured to disperse the conical surface of the liquid during the flow of the liquid. One of the mother points of the Schiffon surface is inclined to a plane perpendicular to the plane of the symmetry (4) of the axial channel, ie, The optimum value 自 [within the range of from about 10 to about 30. (see Fig. 2). The operation of the sprinkler is provided in the following manner and a method for producing an atomized liquid jet is provided. Connected via a threaded connector to the _distribution line (not shown), thereby filling the line and the axial passage 2 of the sprinkler with a working fluid having a pressure range from about 0.4 MPa to about i MPa. In the example, the pressure is 0.6 MPa. When the ambient temperature By a predetermined value (in the example of the embodiment considered, the predetermined value is 68 ° C), the glass ball head 9 is destroyed by the pressure of liquid expansion. - Once the glass ball head is destroyed, it has a valve plug. 8 The pressure of the working fluid filled in the axial passage 2 acts on the "opening" of the axial passage 2. After opening and closing the valve of the axial passage 2 of the injector, the liquid flow flows under a pressure of 〇6 MPa. The filter 6' captures the solid particles that interfere with the normal operation of the nozzle sprinkler by the filter 6. In the axial passage 2, the liquid flow is divided into two streams by the partition wall 3. The partition wall 3 is achieved by means of centering #5 Precisely positioned on the shaft port 2. The inner liquid is fed into the flow passage 4 bounded by the side surface of the partition wall 3 and the inner surface of the centering sleeve 5 in the 101695.doc -17- 1296532 , . The two liquid streams generated in the converging flow channel 2 are characterized by the availability of a central region of maximum density. 2 is an isocenter 1 μ 'liquid parallel to a plane of symmetry of the partition wall 3, wherein the plane is internally filled with heat The response unit is attached to the frame arm 12 of the accessory. During the flow of the cut liquid through the converging flow channel 4, an directional liquid flow flowing at a pre-twisting speed is generated. • The liquid flowing in the flow channel 4 and flowing symmetrically to the symmetrical plane of the partition wall 3 flows in a step-by-step manner It is guided to the outlet opening of the flow channel 4 and then to the outlet opening of the axial channel 2, whereby the resulting liquid stream is atomized. The liquid system is used for the deflection plate 1 and for the thermal response unit The space region defined by the frame arm 12 of the assembly 4 is atomized. By means of the deflecting plate of the continuous central portion 14 of the material, the liquid liquid can be formed in the process of forming the liquid Discharge in a diameter = axial direction. When this liquid flow is separated, a uniformly finely dispersed gas and a droplet jet are generated on the portion of the edge of the deflecting plate 10 at the edge of the edge 5. The body flow reaches the surface of the central portion 14 of the deflector 10 to bypass the frame arm for the heat 7C and the attachment for the deflector. On the surface of the 15 knives 14 in the deflector plate, the liquid which has been initially divided in the flow channel 4: flows through a combination to form a film form in the radial_axial direction flowing toward the deflector plate at the edge 15 &弋 化, melon. When the flow is first to the edge of the deflector 10: on the tapered surface of the eleventh hole, the thickness of the film is reduced and when the liquid slips off the edge of the face and flows over the edge 15 provided on the deflector plate) 101695.doc -18- 1296532 When the hole (hole), the liquid will be divided into small droplets. As a result of one of the established processes, an atomized liquid jet having a radial-axial flow direction characterized by the availability of one of the axial components is produced. The practice has been shown to apply the method for producing an atomized liquid jet and to apply the sprayer for carrying out the method for producing an atomized liquid jet capable of effectively extinguishing a fire scene One of the droplets is evenly spatially distributed and a finely dispersed gas and droplet jet of droplet kinetic energy is added to increase the spray area. In the liquid atomization process, the water is divided into fine droplets having a size of 14 μm or less and a spray intensity of 45 kg/m 2 on an area of 14 m 2 and one on the area. A root mean square deviation equal to or less than 2% produces a jet of uniform gas and droplets. It should be noted that one of the sprayers described in European Patent No. 7 to 1182 can have a spray intensity of one 〇·05 kg/m 2 on an area of 10 m 2 and a ratio equal to or greater than 36% on the area. The intensity root mean square deviation produces a liquid jet having one droplet of 丨〇 micron size and one of the same pressure. Using the well-known AM25_sprinkler from Gnnell, the same pressure can be produced on a 6 m2 area with a spray intensity of 075.075 kg/m2 and a root mean square deviation of 42% of the area. And a gas and droplet jet of one of the average droplet diameters of 3 8 μm. / Therefore, compared to the prior art, the method and sprinkler of the patent application are implemented to ensure that finely dispersed gases and droplets are produced on the surface to be sprayed with high kinetic energy droplets and uniform droplets.
