Definitions

  • the invention relates to a method for changing the swirl movement of a fluid in the swirl chamber of a nozzle and swirl generator for nozzles.
  • nozzles are used in particular in industrial burners, oil burners and plants for flue gas scrubbing and for spray drying of food.
  • the liquid throughput that is atomized can be kept constant, although the speed of entry of the liquid into the swirl chamber can be changed and thus the swirl strength and, consequently, the drop quality can be adjusted.
  • the disadvantage of this solution is the need to circulate liquid.
  • the control range of the spill-return nozzles is limited. There is a significant change in the beam angle over the desired control range.
  • DE 39 36 080 C2 discloses a method for varying the peripheral speed component of the swirl flow of a fluid at the outlet from a swirl nozzle with a swirl chamber with several tangential feeds.
  • the entire material flow of the fluid is divided by division into at least two partial flows, the size of at least one partial flow being changeable.
  • the partial flows are fed to the tangential feed channels of the swirl chamber.
  • the disadvantage is that the achievable control range depends on the number of
  • CONFIRMATION COPY Feed channels is dependent, so that the manufacturing effort for the nozzles with a high control range increases. Although a rotational symmetry of the flow is achieved, the control range remains small.
  • the known nozzles for industrial burners have the disadvantage that the burner output must be kept constant, because otherwise undesirable pollutant emissions occur, especially if the throughput is changed. Often you use several nozzles, whereby optimal conditions can only be achieved for one operating case.
  • the invention had for its object to provide an improved method for changing the swirl movement of a fluid in the swirl chamber of a nozzle, which enables a nozzle to be operated with a large control range and, if possible, a comparable drop quality (average drop diameter and
  • Drop distribution i.e. To create opportunities to be able to regulate the mean drop diameter with a constant volume flow or to keep the drop spectrum constant when regulating the volume flow.
  • a suitable swirl generator for nozzles for carrying out the method is also to be created.
  • the term fluid also means mixtures of different fluids with or without solids.
  • the control options for various nozzle applications created by the new procedure lead to improved productivity of the production systems and to a considerable reduction in costs.
  • the cross-sectional areas should differ by more than four times.
  • the liquid throughput is divided into several partial flows which have different cross-sectional areas.
  • the decisive factors are the cross-sectional areas when the liquid enters the swirl chamber (connection point between the feed channel and the swirl chamber), since the peripheral speed at the periphery of the swirl chamber is determined at this point. If a high swirl strength is desired for a fine droplet spectrum, the partial flow with which the feed channels having the smallest cross-section are applied is to be increased and vice versa. Intermediate values can be set continuously.
  • the simplest way of influencing the throughput of a partial flow is to use a valve.
  • the other aim for which the method can be used is to maintain a certain swirl strength at the exit from the swirl chamber.
  • the ratio of the sum of the cross-sectional areas of the supply channels that are acted upon under full load and the sum of the cross-sectional areas of the supply channels that are acted upon under partial load is to be selected at least as large as the desired ratio of the volume flows under full load and under partial load.
  • the principle of swirl control according to the invention can be used when atomizing liquids in single-substance and two-substance nozzles, in which either the liquid or the gas or both are provided with a peripheral speed in the nozzle.
  • the application is such that the method is applied to both the liquid or the gas or both. It is thus possible to influence the drop quality in two-component nozzles without changing the ratio of liquid throughput / gas throughput. It is irrelevant for what purpose the liquid is atomized. This can be done, for example, for the subsequent drying of a suspension in the drying tower. Oil can also be atomized, which is burned at the nozzle outlet, as is usual with burners.
  • the fluid can also be a gas.
  • the method according to the invention can also be successfully used in gas and coal dust burners, above all to influence the flame shape of the burner.

  • the supply lines 5a and 5b are horizontally spaced from the nozzle plate 2.
  • the openings of the supply lines 5a and 5b are connected via separate lines 8, 9 to a central line 10 for supplying the total fluid flow F G (FIG. 5).

  • the offset radial arrangement of the individual feed channels, with respect to their central axis, by 90 ° in each case, was chosen in this way because of the maintenance of the symmetry of the flow of the fluid into the swirl chamber 3.
  • the method and the device are explained together with regard to reaching the control range.
  • the first step is to consider the case where the drop quality is to remain largely uniform with a variable total throughput. This is a requirement for oil burners, for example.
  • the total liquid throughput F G is divided between all tangential feed channels 4a, 4b, 4c and 4d by forming the tangential partial flows T M> T t2 , T t3 and T t4 .
  • This is done by dividing the total fluid flow F G into two partial flows Ti and T 2 , with which the feed lines 5a and 5b are acted upon.
  • the partial flow T 2 with which the tangential feed channels 4b and 4d are acted upon, that is to say the tantential partial flows Tt2 and T t4 (FIG. 5), can be influenced by a control of the valve 7, ie the throughput of the tangential partial flows T c and T t4 can thus be controlled.
  • the liquid flow Ti is divided between the tangential feed channels T t1 and T t3 .
  • the total throughput drops in the partial load case.
  • the partial flow T 2 in the partial line 8 which supplies the tangential supply channels 4b and 4d via the supply line 5b, is throttled by means of the valve 7.
  • a larger throughput T t and T t3 thus reaches the tangential feed channels 4a and 4c.
  • the entry speed in these feed channels rises there despite falling overall throughput and thus leads to a constant swirl movement at the outlet opening 6 of the nozzle.
  • the lowest limit of constant droplet quality is reached when the total throughput is only passed through the feed channels 4a and 4c and the feed channels 4b and 4d are no longer acted upon. If the total throughput drops even more, an increase in the average drop diameter can be expected.
  • the second case which can be treated with the method according to the invention is the control of the drop size with a constant throughput.
  • the breakdown the partial flows are analogous to the first case. If the droplet size is to be reduced at the same throughput, the partial flow which supplies the feed line 5a is to be increased. The total throughput is to be kept constant by means of an appropriate circuit. If a larger drop size is required, the opposite procedure must be followed.

  • FIG. 8 shows an enlarged top view of a swirl chamber 3, into which two tangential feed channels 4a and 4b open. At the connection point to the swirl chamber 3, the two feed channels 4a and 4b have different cross-sectional areas.
  • the tangential feed channels of a nozzle have the same height at the connection point to the swirl chamber 3 and, if necessary, can have different widths, as illustrated in FIG. 9 by the width dimensions Bi and B 2 .
  • the respective width dimension is the distance between two intersection points Si and S 2 lying on a parallel line to the central axis M, the intersection point S being the intersection point between the circumferential surface of the swirl chamber and the wall of the tangential feed channel adjacent thereto and the intersection point S 2 being the intersection point the parallel line with the opposite wall of the tangential feed channel.
  • connection point of the tangential feed channels to the swirl chamber can also be designed as a circular cross-section, in which case different cross-sectional areas can be achieved in an analogous manner at this point through different diameters of the respective bores.
  • the tangential feed channels 4a and 4b can be designed differently outside the connection point to the swirl chamber, for example have a constant channel cross section or the channel cross section tapers in the direction of the swirl chamber. In the case of two tangential feed channels of a nozzle, as shown in FIGS. 9 and 10, it is absolutely necessary that these channels have different cross-sectional areas at the connection points to the swirl chamber.
  • the ratio of the diameter Di of the nozzle outlet opening to the diameter D 2 of the swirl chamber should be in a range from 2 to 12. If a nozzle is designed with a plurality of tangential feed channels, it is expedient if these are distributed uniformly over the circumference or the inner lateral surface of the swirl chamber. It has proven to be advantageous if the swirl chamber and the cross sections of the tangential feed channels at the connection point Swirl chamber can be dimensioned according to a certain ratio, as follows:
  • B is either the width or the diameter of the channel at the point of connection to the swirl chamber and D or D 2 are the diameters of the outlet nozzle or swirl chamber, as explained above.
  • the swirl chamber has a smaller dimension than the diameter.
  • the speeds on the inner swirl chamber casing can also be lower than in the case of smaller swirl chamber diameters, since higher circumferential speeds are formed because of the greater radial distance from the nozzle outlet opening. Therefore, with larger swirl chamber diameters, the cross-sectional areas of the feed channels can be made larger. This makes the manufacture of the tangential feed channels easier and reduces the risk of clogging. If the ratio of the swirl chamber diameter to the nozzle outlet diameter is too large, however, the peripheral speed decreases due to the wall friction.
  • FIGS. 11 to 13 show different circuit arrangements for different versions of the nozzles.
  • the control intervention in the throughput of the fluid flow outside the nozzle is carried out either via a valve or separate pumps.

  • the case with constant fluid flow is discussed.
  • the liquid is supplied via a line and two sub-streams are formed by branching.
  • the size of one partial flow can be limited by a valve. After the valve, it is fed to the feed channel with the larger cross-sectional area.
  • the two limit cases exist when the valve is fully open or closed. When the valve is fully open, the liquid throughput is distributed over both supply channels.
  • the peripheral speed on the inner surface of the swirl chamber has its lowest value and thus the peripheral speed at the nozzle outlet is also the lowest.
  • the circumferential speed at the nozzle outlet takes on the greatest value when the valve is closed.
  • the ratio of the smallest cross-sectional area to the total cross-sectional area of both feed channels determines the ratio of partial load to full load that can be achieved and at which the atomization properties do not change essentially.
  • the circuit variant shown in FIG. 11 corresponds to the nozzle shown in FIG. 6 with a swirl body 12 according to FIG. 8.
  • the circuit variant shown in Figure 12 differs from the circuit variant shown in Figure 11 only in that the partial stream T 2 is not divided into a tangential partial stream but three tangential partial streams T ⁇ , T t3 and T t4 , the sum of which from the cross-sectional areas of tangential feed channels at the connection point is larger than the analog cross-sectional area for the tangential partial flow T t1 .
  • the configuration of the nozzle is analogous to that in the embodiment according to FIG. 12. The difference is that there is no branching off of a total fluid flow, but two separate partial flows T and T 2 independently of one another via eccentric screw pumps integrated in the lines 11, 11 'are influenced by a

  • the present invention can also be used in cases where it is necessary to keep the jet angle of the fluid emerging from the nozzle constant at different throughputs, that is to say to influence the control of the jet angle. With conventional swirl nozzles, a larger jet angle is achieved with increasing throughput.

Abstract

L'invention concerne un procédé qui permet de modifier le mouvement de rotation d'un fluide dans la chambre de rotation d'un gicleur et un générateur de rotation pour gicleurs. Ces gicleurs sont notamment utilisés dans les brûleurs industriels et les brûleurs à mazout, ainsi que dans les installations de purification des gaz de combustion et de séchage des aliments par pulvérisation. En raison des inconvénients liés à l'état actuel de la technique, il est nécessaire de proposer un procédé et un gicleur qui permettent, en cas de débit constant, de réguler le diamètre moyen des gouttelettes ou bien, en cas de régulation du débit, de maintenir constant le spectre des gouttelettes. A cet effet, les flux partiels (T1, T2) sont répartis entre plusieurs canaux d'alimentation (4a, 4b, 4c, 4d) ayant des sections différentes au niveau de leur zone de raccordement avec la chambre de rotation (3). Si les flux partiels (T1, T2) se répartissent entre plus de deux canaux d'alimentation (4a, 4b, 4c, 4d) tangentiels, les sections sont représentées par la somme des sections des canaux partant de chaque flux partiel (T1, T2) et, par suite, les sommes des sections au niveau de la zone de raccordement (S1, S2) des flux partiels (T1, T2) avec la chambre de rotation (3) sont différentes.
