Detailed description of the invention
In Fig. 1 and Fig. 2, a kind of microchannel high-efficiency wet electrical dust precipitator, contains housing 1, some groups of dust collector pole rows 2, some groups of discharge electrodes 3, dust collector pole spray system 4 and discharge electrode Ash Removal Systems.Every group of dust collector pole row 2 are staggered in housing 1 inner chamber parallel with every group of discharge electrode 3.Dust collector pole spray system 4 is located at dust collector pole row 2 top, and discharge electrode spray system 5 is arranged in the top of discharge electrode 3, and leaves insulation distance with discharge electrode 3.Every group of dust collector pole row 2 is made up of some strip positive plates, and some strip positive plates are equidistantly in line, every group of discharge electrode 3 is arranged in two two adjacent groups dust collector pole rows 2, and arrange 2 parallel with two two adjacent groups dust collector poles, and distance is equal, and the spacing between described strip positive plate is 40mm ~ 100mm.As shown in Figure 3, the equal free suspension in upper end of described some strip positive plates 6 is on pole plate hanging beam 7, pole plate hanging beam 7 hangs on the anode crossbeam 8 that described housing 1 internal upper part is provided with, and insert in the location guiding gutter 9 that described housing 1 inner bottom part is provided with the lower end of described some strip positive plates 6.The cross sectional shape of described some strip positive plates 6 can be waveform, semicircle or Ω shape, and described some strip anode 6 plates are 50mm ~ 200mm along flue gas circulating direction effective length, and the length of described some strip positive plates 6 is 2m ~ 12m.As shown in Figure 4, described dust collector pole spray system contains spray header 10, this spray header 10 is arranged on described pole plate hanging beam 7, spray spout 11 is equipped with in these spray header 10 bottoms, spray spout 11 is two-way shape nozzle, this two-way shape nozzle 11, through described pole plate hanging beam 7, points to respectively described dust collector pole and arranges 2 adjacent strip positive plates 6, and spray spout 11 is positioned at the center of adjacent strip positive plate 6 passages.As shown in Figure 5, described every group of discharge electrode 3 is equipped with some discharge lines 12, and discharge lines 12 is made up of pipe 13 and acupuncture 14, is equidistantly arranged in discharge electrode framework 15, and the spacing of adjacent discharge lines is 300mm ~ 600mm.As shown in Figure 6, described discharge electrode Ash Removal System 5 contains sluicing noz 17 and rushes grey water pipe 16, sluicing noz 17 is arranged on and rushes on grey water pipe 16, all discharge lines 12 described in corresponding of sluicing noz 17, and install with described discharge lines 12 off(-)centers, dislocation distance is 100mm ~ 250mm, and each sluicing noz 17 targets are aimed at corresponding discharge lines 12.The utility model is compared with existing wet electrical dust precipitator, and under equal spatial volume, Flow Field Distribution is even, can improve flue dust collecting efficiency; Special micro-channel structure between some strip positive plates 6 of dust collector pole row 2, shortens charged particle and positive plate distance greatly, high to fine solid particle and water smoke collection efficiency.When work, flue gas enters in it from the import of housing 1, and in the time entering first order electric field space, a large amount of electronics that the particle in flue gas and electric field internal ionization produce are charged with bumping, and under the effect of flue gas negative pressure, arrange 2 diffluences to dust collector pole.In the time that flue gas enters dust collector pole and arranges the microchannel of 6 of 2 some strip positive plates, under the effect of electrostatic force, charged particle thing is rapidly to pole plate diffluence, flue gas through first class purification enters electric field space again, again charged, so repeatedly, after several grades of dust collector poles purify, flue gas finally flows out through the outlet of housing 1.The duty of described dust collector pole spray system 4 is operation continuously, and anode arranged plate 2 surfaces continue film forming, can ensure never dust stratification of polar board surface.Described discharge electrode Ash Removal System 5 is intermitten service, because discharge electrode Ash Removal System 5 is connected with housing 1, for zero potential, therefore rushing buck is also zero potential, is communicated with discharge lines 3 if rush grey current, discharge electrode 3 is also zero potential, this will cause deduster ground connection not worked, and therefore, rush buck and will be interrupted feedwater, before and after ensureing, current have insulation distance, guarantee deduster normal operation continuously.The utility model is administered flue gas after desulfurization, can guarantee that exporting soot emissions is down to 10mg/Nm
3below, even reach zero-emission.
