Definitions

  • the invention relates to a Rauchpumbleabscheider for filtering particulate matter, soot and / or smoke particles from flue gas flowing through a chimney draft with a filter which is arranged in a housing. Furthermore, the invention also relates generally to smoke particle separators, and more particularly to those provided with a filter designed as a motor driven rotary filter grid.
  • Known Rauchpumbleabscheider are intended for single ovens and are usually in the exhaust pipe of the single oven, ie between the fireplace and fireplace introduction.
  • the mounting or retrofitting of such Rauchpietyabscheider are basically a problem because of the limited, available space.
  • the cleaning of such Rauchpietyabscheider is often associated with pollution of the surrounding space. This room, especially the living space around a single oven, but should actually not be polluted by such activities just.
  • the invention has for its object to provide a Rauchpumbleabscheider, which does not have the disadvantages mentioned above, is inexpensive to manufacture and monierbar and beyond only low maintenance needs.
  • a Rauchp for filtering out smoke particles from a flue gas flowing through a chimney flue, which comprises a filter which is arranged in a housing, and wherein the housing is adapted to a frame mounted on a chimney door of an associated chimney to become.
  • the smoke particle separator according to the invention is arranged on the frame of a chimney-cleaning door or the Schomstein cleaning closure of an associated chimney or chimney and replaces the chimney-cleaning door otherwise attached there.
  • the Rauchprissaabscheider uses an existing anyway Opening in the fireplace to which it is attached, and in particular must not be installed by a subsequent separation of an existing building structure in this.
  • Chimney cleaning closures of chimneys and chimneys are standardized according to the standard PA IV and therefore largely the same size and shape. Therefore, the Rauchpietyabscheider invention is particularly advantageous designed so that it can be easily hooked into the hanger of a frame located on the chimney chimney door and coupled by pressing against the frame of the chimney door largely gas-tight to the chimney.
  • the Rauchpietyabscheider is particularly preferably arranged on the frame of the upper chimney door, which is usually located in the attic of the associated house and therefore in a space or area, which is already contaminated by the cleaning of the fireplace.
  • the Rauchpietyabscheider invention must only be swung away from the fireplace, so that the fireplace can be cleaned as usual.
  • a slide is provided, which is adapted to be pushed out of the housing of the Rauchpietyabscheiders and into the chimney to lock the local chimney draft and redirect the flue gas into the housing.
  • the slide not only serves to shut off the actual draft train, but at the same time releases a flow path through the associated filter in the smoke particle separator according to the invention.
  • a flap can also be advantageously used. By means of this, a chimney draft can be closed, which is larger in diameter than the width of the associated chimney cleaning door.
  • a Rauchpumbleabscheider in particular of the above type, created with a filter which is designed as a motor-driven, rotating filter grid, and in which the filter grid is designed as kalandertes grid.
  • the filter grate rotating according to the invention is a round body, which is flowed in from the outside by the flue gas. Inside, the filter grid is hollow. It moves its filter surface or filter wall accordingly transversely to the flow direction of the flue gas and acts as follows: The flue gas flows with the particles contained therein to the grid, which moves due to its rotation with relatively high velocity transverse to this gas stream. Now, the much higher specific weight of the smoke or dust particles in comparison to gas or air to advantage.
  • the inertia of the particles is about 1500 times greater than that of the air.
  • the particles are torn from the air stream by the transversely moving grid at the boundary layer between filter grid and flue gas.
  • the gas or air passes through the grid largely unhindered.
  • the ability of the particles to be carried by the air after impact is very low because they have previously been compressed by the rapidly moving grid with other particles.
  • the rotating grid also has the advantage that it acts like a centrifugal drum and the resulting centrifugal force "sucked" the smoke particles outward from the filter.
  • the filter drum according to the invention preferably rotates at a speed of between 1000 U / min and 3000 U / min whereby a centrifugal force of up to 800 g can be generated.
  • the filter thus cleans itself constantly.
  • the thrown off Dust material is the more pre-lumped by hitting the surrounding housing and falls after hitting the housing wall down.
  • Conventional braided grids are made of wire mesh having the thickness of twice the associated wire diameter.
  • the surface of such wire mesh is formed by arch wires.
  • the grating according to the invention is calendered and therefore has the strength of only one wire and its surface comprises flat, elliptical surfaces. These surfaces are created by compressing the two intersecting wires to only one wire gauge.
  • the interface of such a calendered grid is so thin that the above-mentioned effect of tearing particles out of the gas stream can be achieved to a particular degree. It creates only a particularly thin co-rotating with the filter gas layer.
  • a Rauchpumbleabscheider in particular of the above type, created with a filter which is designed as a motor-driven, rotating filter grid, and in which an impeller is provided, which is mounted co-rotating with the filter grid.
  • the thus co-rotating impeller generates on the said filter a suction which sucks the flue gas with the air contained therein through the grid otherwise moving transversely to this gas flow.
  • the impeller acts advantageously as a tension control or Buchbegrenzung in the associated fireplace.
  • the object is achieved according to the invention with a Rauchpumbleabscheider, in particular of the above type, with a filter which is designed as a motor-driven, rotating filter grid, and in which the filter grid is designed in the shape of the lateral surface of a truncated cone, the base in Installation position of the smoke particle separator is at the top.
  • the truncated cone shape is particularly advantageous because the flowing through the filter flue gas inside the truncated cone can flow without resistance, as in a purely cylindrical shaped filter grid.
  • purified flue gas which has passed through the grating at the lower end of the truncated cone can ascend upward in the radially inner region of the truncated cone, while gas which has passed through the grating in the upper region of the truncated cone continues radially outwards to the base, ie to the flared Side of the truncated cone and can flow from there further back into the fireplace.
  • a collecting container for smoke particles is arranged under the filter.
  • the collecting container takes the filter particles from the air stream torn filter particles, which are thrown off the filter grid, collects them and holds them back, so that they are not stirred up again by the subsequent Rauchgastrom. Since in the construction according to the invention the entire housing is located on the associated chimney cleaning door outside the chimney, the collecting container for emptying is particularly accessible.
  • the object is also achieved with a heating system with a boiler and a Rauchpumbleabscheider of the type mentioned above with a co-rotating impeller in which the Rauchpietyabscheider is arranged with its impeller in the flue of the boiler and replaced with its impeller the induced draft fan of the boiler.
  • the Rauchprissaabscheider is preferably located in this solution immediately behind the heat exchanger of the boiler and is thus in the smoke pipe section between the boiler and fireplace.
  • the Rauchpietyabscheider is integrated into the control of the boiler or coupled to it in such a way that with its impeller suction or negative pressure for the operation of the boiler can be generated.
  • the Rauchpietyabscheider replaces with its impeller on the boiler a there previously provided Saugzuggebläse. The replacement can be made later on already existing systems or already in the design and development of heating systems. This solution is accordingly very cost-effective overall.
  • a Rauchpumbleabscheider 10 is shown, which is arranged on a chimney or chimney 12.
  • the chimney 12 is formed with a tubular, square in the outer cross section of the chimney wall 14, in which a substantially circular cylindrical chimney 16 is located.
  • the chimney 16 is accessible from the outside through a chimney-cleaning door, from which only the frame 18 is located on the chimney 12.
  • the wing of the chimney cleaning door has been posted and removed. Instead, on a hinge 20 of the chimney-cleaning door a connection to the Rauchpietyabscheider 10 associated fitting 22 mounted.
  • the connecting piece 12 connects to the frame 18 in a tubular manner and establishes a flow connection to a substantially cuboidal housing 24 of the Rauchparükelabscheiders 10.
  • the housing 24 is separated by a horizontal separating surface 26 into a lower chamber 28 and an upper chamber 30.
  • a slider 32 is mounted, which can be inserted from the separation surface 26, starting in the chimney 16, that it interrupts the vertical flow path and discharges the bottom of the chimney 16 entering flue gas into the lower chamber 28.
  • the slider 32 is movable by means of a rod-shaped actuator 34 which is driven by an energy store 36.
  • the energy storage 36 is formed with a (not illustrated in detail) electromagnet and a spring which cause in the case of energization of the electromagnet sliding out of the slider 32 and ensure retraction of the slider 32 in case of power failure. The slider 32 is then in the retracted state the chimney 16 completely free again.
  • a circular opening 38 is formed, through which the flue gas from the lower chamber 28 can reach into the upper chamber 30 and further back into the chimney draft.
  • the opening 38 is centrally penetrated by a shaft 40 which is rotatably mounted in a lower bearing 42 at the bottom of the housing 24 and in a bearing 44 in the separating surface 26.
  • a coupling 46 and another bearing 48 Above the bearing 44 is a coupling 46 and another bearing 48, with which the shaft 40 is mounted on the top surface of the housing 24.
  • a motor 50 is arranged, with which the shaft 40 is driven and set in rotation during operation of the flue gas particle separator 10.
  • the clutch 46 serves to facilitate assembly and disassembly of the engine 50 during maintenance.
  • a frustoconical filter grille 52 is rotatably mounted on the shaft 40 as a filter of Rauchpumbleabscheiders 10.
  • the filter grid 52 is designed with a calendered grid as shown in FIG Fig. 2 is shown.
  • the truncated cone of the filter grid 52 is aligned with its base upwards, so it is upside down, so to speak.
  • an impeller 54 with which the flue gas is sucked into the chamber 28 and through the filter grid 52 and subsequently pushed further into the chamber 30.
  • the flue gas passes through the driven by the motor 50, rotating filter grille 52, at the outer boundary surface, the particles are torn from the flue gas.
  • moving filter grid 52 is located at the bottom of the chamber 28, a collecting container 56, in which the particles fall down and collect.
  • the collecting container 56 is designed in the manner of a drawer and can be emptied accordingly if necessary.
  • a heating system 58 which comprises a boiler 60 having a smoke tube 62 disposed thereon.
  • the flue pipe 62 terminates in a chimney (not shown).
  • the boiler 60 is designed with a housing 64 and a combustion chamber 66 arranged therein and a heat exchanger 68. From the heat exchanger 68, the flue gas passes directly into the flue pipe 62, which leads out of the housing 64.
  • a Rauchpenieabscheider 10 is arranged, which is also designed with a rotating, frusto-conical filter grille 52 which can be set by a motor 50 along its truncated cone axis in rotation.
  • the truncated cone axis extends in the direction of the flue pipe 62, wherein the flue pipe 62 in Flow direction is designed behind the Rauchpietyabscheider 10 with a manifold in which the associated shaft 40 is led out of the flue pipe 62.
  • the smoke particle separator 10 according to Fig. 3 In particular, it is also designed with a calendered grid, a collecting container 56 arranged underneath and an impeller 54.
  • the impeller 54 is dimensioned and designed so large that it can replace a conventional induced draft fan of the boiler 60.
