Definitions

  • the invention relates to an electrostatic precipitator, in particular for exhaust air purification for road tunnels, underground garages od.
  • an electrostatic precipitator in particular for exhaust air purification for road tunnels, underground garages od.
  • From at least one flow channel forming a filter cell with an inflow ionizing and an outflow collector, wherein the ionizing used in a frame, extending over the flow cross-section electrodes and a collector grounded, the flow cross-section covering filter mat made of wire wool od.
  • Is provided US 4 222 748 A ).
  • a road tunnel Like. Contains solid particles, such as diesel soot, tire or road surface abrasion, dust u. Like., And also liquid particles, which particles must be deposited for environmental reasons or for reuse of the purified air in the tunnel.
  • Mechanical filter systems are less suitable because they are associated with large pressure losses and make high demands on the fan performance because of the considerable amounts of air required. Accordingly, electrostatic precipitators which operate on the Penney principle are used for this exhaust air purification, wherein an electric field for ionizing the particles to be separated is generated in an ionizing device by means of electrodes applied to a high DC voltage, whereby the charged particles are subsequently immersed in a collector Delivery of their cargo are knocked down.
  • the collector is set to date by far from each other arranged, alternately positive and negative collector plates together, so that the ionized particles of the air flowing between the collector plates exhaust air are repelled depending on the charge from one collector plates and attracted by the other and by this distraction they settle collecting collector plates.
  • the separation efficiency of these filters especially in terms of extremely small soot particles unsatisfactory.
  • these electrostatic filters fail in case of fire, in which a smoke separation would be very important because of the visibility, since the operating temperature is usually about 65 ° C and the ionizer and the collector of a fire corresponding temperature load of about 250 ° C not withstand.
  • the invention is therefore an object of the invention to provide an electrostatic precipitator of the type described above, which is characterized by its high separation efficiency and fire performance in relatively low-cost construction and can also be rationally clean beyond.
  • the invention solves this problem in that the filter mat is associated with a blower comprising a Ausblasdüsenech on the downstream side of the filter mat and a suction hood unit at the inflow side, wherein the opposing Ausblasdüsen- and suction hood units are guided back and forth together along the mat surface.
  • the electrodes can be configured as desired, as long as they produce an evenly distributed over the flow cross-section electric field, advantageously sheet metal strip stainless steel serve as electrodes, of which alternately one grounded and the other are connected to a high voltage source and the high voltage source connected sheet metal strip jagged edges for a Spitzenionmaschine form.
  • the collector consists of a filter mat
  • the ionized particles no longer need to be deflected transversely to the direction of flow to corresponding collector plates, because they must forcibly contact the grounded mat material when penetrating the filter mat and are thus deposited, as a filter material Wire wool or similar wire material, such as wire mesh and wire mesh, but also nonwovens u. Like. Of metal, ceramic, plastic or other suitable conductive materials is used.
  • This filter mat is insensitive to temperature and brings with the failure of the ionization by collapse of the high voltage as a purely mechanical filter, a separation effect, without because of the looser Structure to cause higher pressure drops. Due to the interaction of lonisier Spur and filter mat sufficiently good separation performance are also guaranteed even at high flow rates, which are also largely independent of temperature because of the temperature capacity of the ionizer and the collector.
  • the filter cells are usually arranged side by side in parallel, but also quite to achieve reinforced separation effects in series can be stringed.
  • Several filter cells can also be combined to form a large filter cell, which forms a common flow channel and accommodates the ionizing units combined into an ionizing unit in a frame housing on the inflow side and the collectors of the individual filter cells combined to form a collector unit.
  • the filter cell may further include a water injection device with spray nozzles provided in front of and / or behind the filter mat for additional air washing, so that not only the particle separation can be influenced by the resulting water mist or curtain, but also gas separation can be achieved.
  • the spray nozzles can sit in adaptation to the particular conditions in front of the ionizing device, which is expedient for example in case of fire, or after the ionizing device so as not to impair the ionizing process, and they can also be arranged behind the collector and the water against the direction of flow through the filter mat, which in addition to the washing effect of the separation effect increases and a filter cleaning effect is achieved.
  • a filter cell 1 of an electrostatic precipitator consists of a cell housing 2, which forms a flow-through channel 3 and on the inlet side an ionizing device 4 and on the outflow side a collector 5 receives.
  • the ionizing device 4 has arranged in a frame 6 electrodes 7, 8, which extend at a mutual distance parallel to each other across the flow cross-section and alternately strip-shaped Erdungsblechen 81 and lonisierblechen 71 consist.
  • the ground plates 81 are mounted at one end fixed to a support rod 9 of the frame 6 and suspended at the other end via a suspension spring 10 resiliently on a suspension rod 11, wherein there is a ground terminal for the frame 6 and the grounding plates 81.
  • the formed with a serrated edge 72 lonisierbleche 71 are similar to the Erdungsblechen one end firmly mounted on a connecting rod 12 and the other suspended via a suspension spring 13 on a suspension rod 14, which lonisierbleche 71 but via the connecting rod 12 in a manner not shown with a high voltage source in line connection stand.
  • This connecting rod 12 is insulated from the frame 6 by means of insulators 15, and passage openings 82 in the earthing plates 81 prevent electrical contact between grounding plates and connecting rod.
  • a flow cross-section covering filter mat 16 made of wire wool od. Like. Used. If exhaust air flows through the filter cell 1, the particles contained in the exhaust air are ionized by the electric field generated by the electrodes 7, 8 in the ionizing device 4 and then reach the collector 5, where they are deposited and deposited in the grounded filter mat 16. Due to the spring-related stretchable suspension of the electrodes 7, 8 and when using a temperature-resistant material as a filter mat 16, the filter cell 1 is fire-safe and because of the filter mat as a collector results even for high flow rates a good separation efficiency.
  • the collector 5 of the filter mat 16 is associated with a blower 17, which comprises a Ausblasdüsentician 18 on the downstream side 161 of the filter mat 16 and a suction hood unit 19 on the inflow side 162 of the filter mat 16, wherein the opposing Ausblasdüsen- and suction hood units 18, 19 means Screw spindles 20, 21 are guided back and forth along the mat surface.
