Definitions

  • the invention relates to an electric filter for a firing system, in particular for a domestic firing system, with an ionization chamber with a filter electrode assembly in the flow path of the flue gas, wherein the filter electrode assembly is arranged in a substantially straight portion of the flow path of the flue gas, and a plurality aligned in the direction of flue gas flow and preferably formed as rods or plates spaced apart electrodes, which are arranged parallel to the flow axis of the flow path.
  • an electric filter for a combustion plant which has a first and a second swirl chamber for the flue gas.
  • a filter electrode assembly is provided with an insulator which is arranged in the purge air flow.
  • the electrostatic precipitator further comprises a second vortex chamber which is connected to a tubular outlet of the first vortex chamber and formed so that the particles located in the flue gas are deposited in it.
  • the cleaned flue gas can escape from the electrostatic precipitator.
  • the filter electrode arrangement has horizontally extending, star-shaped arranged first electrodes and a vertically oriented, emanating from the intersection of the first electrode second electrode. At least part of the electrodes is arranged transversely to the flow.
  • an electrostatic filter for a firing system which has a rod-shaped central and arranged in the direction of the flow axis of the flue gas filter electrode, an electrode holder, via which the filter electrode is held in an exhaust pipe of the furnace and supplied with voltage, and an insulator which surrounds the electrode holder.
  • two baffle plates, which are arranged on the insulator and a scavenging air opening are provided in the electrostatic precipitator, wherein scavenging air can be guided in the direction of the plate via the scavenging air opening. The purge air is thereby guided so that a particle deposition of the housing is avoided and thus the efficiency of the filter is maintained for a long time.
  • This electrostatic precipitator is suitable for installation in a flue gas flow path between the furnace and the chimney.
  • the disadvantage is that by the only one central center electrode, the deposition rates, especially for use as a chimney cowl, too low.
  • an electrostatic filter for a furnace known, which can be placed for example on a fireplace.
  • the electrostatic precipitator consists of a frame, which is placed on the chimney, an insulator that protrudes from the frame inside in the middle of the frame and at the end of a weighted electrode hangs and protrudes into the chimney.
  • the electrostatic precipitator is used to hold back the particles in the flue gas.
  • a high voltage is applied to the electrode, with the result that the particles are electrostatically charged and reflected by the chimney and the frame.
  • this may result in prolonged operation of the electrostatic precipitator, the particles that accumulate on the insulator form an electrically conductive bridge due to their electrical conductivity between the insulator and the frame and thereby degrade the effect of the insulator.
  • the WO 1993/16807 A1 discloses an electrostatic filter having an ionization chamber and a filter electrode assembly in the flow path of the gas, wherein the filter electrode assembly is disposed in a substantially straight portion of the flow path of the gas.
  • the filter electrode assembly has a plurality of electrodes formed as parallel plates, which are aligned in the direction of gas flow.
  • the disadvantage is that the known electrostatic filter arrangement takes up a lot of space and causes a relatively high throttling of the flue gases. For subsequent installation in a chimney, the device is therefore less suitable.
  • the object of the invention is to avoid the disadvantages mentioned and to effectively clean the flue gases of domestic fire furnaces in a space-saving manner, with particular attention to be directed to simple retrofitting in existing firing systems.
  • the electrodes are connected to one another by a preferably annular conductor comprising the rods or plates.
  • the electrodes are advantageously rotationally symmetrical with respect to the flow axis of the flue gas flow, in particular arranged rotationally symmetrical with respect to the center axis of the chimney.
  • Electrodes are concentric with the annular conductor. It is particularly advantageous if the electrodes are arranged substantially in a star shape.
  • the electrodes formed by plates intersect in the region of the flow axis and are connected to one another.
  • the chimney cowl is releasably connected to the chimney, wherein preferably the chimney cowl is attachable to the chimney or hingedly connected thereto by a hinge.
  • the ionization chamber is formed by a ceramic inner tube.
  • the ceramic inner tube advantageously surrounds the filter electrode arrangement.
  • a straight separation region is arranged downstream of and in alignment with the ionization chamber, wherein preferably the separation region is formed by a separator tube, preferably made of stainless steel, whose axis is aligned with the flow axis of the chimney, and when upstream of the ionization chamber, there is disposed a stainless steel insert tube whose axis is aligned with the axis of the ionization chamber and with the axis of the deposition region.
  • a removable stainless steel inner tube can be inserted into the separator tube with an exact fit. If necessary, the inner tube can be removed and cleaned or replaced.
  • the electrostatic filter has a mounting plate upstream of the ionization chamber.
  • Turbulence and turbulence in the area of the filter electrode arrangement have an advantageous effect on the deposition rates.
  • the ionization chamber is expanded discontinuously in the transition region to the insertion tube and to the separation region.
  • an electrical insulator is arranged around the separation area and around the ionization chamber.
  • the ionization chamber is formed by a T-shaped tube, wherein a high-voltage generator, which is conductively connected to the filter electrode arrangement and the deposition region, is subsequently arranged on the opening tube part of the T-tube.
  • Fig. 1 shows a chimney 1 on the mouth 2 as a chimney cap 3 trained electrostatic filter 4 is arranged.
  • the electrostatic filter 4 has an ionization chamber 6 formed by a ceramic inner tube 5, in which a filter electrode arrangement 7 is arranged. Furthermore, the electrostatic precipitator 4 has a push-in tube 8, which can be pushed into the mouth 2 of the chimney 1, as well as a separation region 10 which is connected downstream of the ionization chamber 6 and is surrounded by an electrical insulation 11.
  • the ceramic inner tube 5 is formed as a T-shaped tube, wherein an installation space 12 connects to the transverse opening pipe part 5a for a shielded against the environment high voltage generator 13, the electronics is protected by a weather protection 15.
  • the filter electrode assembly 7 and on the other hand the separator 9 of the deposition area 10 is electrically connected.
  • a replaceable inner tube 9a may be inserted on the stainless steel, which may be removed as needed for cleaning or changing.
  • the axis 8a of the insertion tube 8, the axis 6a of the ionization chamber 6 and the axis 10a of the deposition area 10 are aligned with each other.
  • the ionization chamber 6 has a larger cross-section than the insertion tube 8 and the separation region 10, between the insertion tube 8 and the ionization chamber 6 on the one hand, and the ionization chamber 6 and the ionization chamber 6 Abscheide Scheme 10 on the other hand take place sudden cross-sectional transitions.
  • the unsteady change of the flow cross-section causes turbulences to form in the inlet region 16 as well as in the outlet region 17, which with W in Fig. 1 are designated.
  • the chimney cap 3 has a mounting plate 18 made of stainless steel, which is releasably secured to the edge of the chimney muzzle. Since the insertion tube 8 is only inserted into the chimney 1, the chimney cap 3 together with the filter electrode assembly 7 can be removed by pulling out the insertion tube 8 from the mouth 2 of the chimney 1 for cleaning.
  • the chimney cap 3 may also have a hinge 19 in the region of the mounting plate 18, around which the chimney cap 3 can be tilted during cleaning.
  • an annular or rock-shaped arrangement of the electrodes 7a, 7b in the form of rods or plates is advantageous.
  • the Fig. 2 and Fig. 3 show an embodiment in which the electrodes 7a of the filter electrode assembly 7 are formed as a circularly arranged rods, which are arranged concentrically to the flow axis 1a of the chimney 1.
  • the rods are comprised of an annular conductor 20, which is connected to the high voltage generator 13 via a rod-shaped conductor 21.
  • FIG. 5 show a further embodiment in which the electrodes 7b are formed as arranged radially with respect to the flow axis 1a of the chimney 1 plates, wherein the plates are connected via a comprehensive annular conductor 20 and a rod-shaped conductor 21 to the high voltage generator 13.
  • it is for a possible unhindered Flue gas outlet advantageous if the center axes of the inner tube 9, the ionization chamber 6 and the insertion tube 8 are aligned with the flow axis 1 a of the chimney 1.
