Description
Affiliated field
thisfa Ming Wataru and a kind of for collecting the electric cleaner of micron order aerosol smokeshade, especially can carry out to being less than PM2.5 micron order aerosol smokeshade a kind of electric cleaner that screen mesh type dust collecting anode board is installed of efficient trapping.
Background technology
Known, the various dedusters of current all domestic and international application, all could not be collected being less than PM2.5 micron order aerosol smokeshade, cause and are less than PM2.5 micron order aerosol smokeshade, are all discharged in atmosphere! Cause haze weather, cause environment for human survival severe exacerbation! Industrial air pollution, a serious threat mankind bottom line of substantially surviving! Therefore, thoroughly stop the discharge of the following harmful substance particle of PM2.5! Being to form huge social demand, is the essential of human survival.For this reason, I had once invented [a kind of ultra-low concentration discharge electric cleaner] patent No. 200610047963, with [Combined electric dust remover] patent No. 201010244404. 7, the experiment proved that this technology, only in the first electric field, just can remove the above flue dust of 99.9 ﹪, from the efficiency of dust collection of electric field 80 ﹪ of old-fashioned electric cleaner, bring up to 99. 9 ﹪ efficiency of dust collections, but in the second electric field, [a kind of combined type dust collecting anode board] adopting, due to structural limitations, oneself is through being not suitable for residue less than 1 ﹪, and be less than again PM2.5 micron order aerosol smokeshade and effectively trap, this just requires to seek, and a kind of have can be to being less than PM2.5 micron order aerosol smokeshade, the Novel electric dust arrester more effectively trapping.
?
Summary of the invention
In order to overcome existing electric cleaner, can not efficiently trap being less than PM2.5 micron order aerosol smokeshade.The invention provides a kind of can efficiently trapping being less than PM2.5 micron order aerosol smokeshade, the electric dust collector of screen mesh type positive plate is installed, thereby, can limit the discharge that is less than PM2.5 micron order aerosol smokeshade! Haze is effected a radical cure! The object of this invention is to provide a kind of electric cleaner and manufacture method thereof that adopts screen mesh type positive plate.
The technical scheme that technical solution problem of the present invention adopts is that ﹕ is by the pertusate screen stencil sheet of distribution, be fixed on a plane framework, make screen mesh type anode superstructure, simultaneously that n corona discharge polar curve is parallel, equidistantly, arrangement is fixed on a plane framework, make cathode frame, by two identical anode superstructures, side by side, parallel, after fixing, again in the centre of two anode superstructures, with insulation section bar, hang to install and fix one side by side, parallel cathode frame, make a combined type dust collect plant, in the casing of electric cleaner, by 1-n dust collect plant, perpendicular to air motion direction, be arranged in parallel into the electric field that hoover system with the horizontal dust-collecting net grid of multiple tracks, in the casing of electric cleaner, arrange 1-n the electric field that hoover system of installing, because, in screen mesh type electric cleaner, by the electric field that hoover system of dust-collecting net grid, perpendicular to air motion direction, the installation being arranged in parallel, this just can force whole charged flue dust air-flows, must all from the hole of anode screen, pass through respectively, thereby, make each charged smokeshade that is less than PM2.5, can obtain closely and screen mesh type positive plate touch opportunity, known, Coulomb's law formula, f=к .Q .Q/r2, because к is constant, under Q .Q value permanence condition, because r2 is negative square value, changes r size, to Coulomb force f size, has tremendous influence!
When being 0.2m apart from r, r2=0.22=0.04 ﹙ is in former old-fashioned electric cleaner, homopolarity distance is 0. 4m, and corona discharge polar curve and pole plate heteropole distance are 0. 2m, so, PM2.5 soot dust granule distance after charged is 0.2m with the positive plate maximum distance that gathers dust, the surface area that cause is less than PM2.5 soot dust granule is little, charged electron number also just very little, again because anode is apart from too far away, so its coulomb of absorption gravitation is too little, again because structural design is unreasonable, cause major part to be less than PM2.5 micron order aerosol smokeshade, cannot with positive plate close contact, finally make great majority be less than PM2.5 micron order aerosol smokeshade, by air-flow, swept along and emit.﹚
If the mesh diameter of new-type screen mesh type positive plate is designed to 0.02 m, manage again to force the PM2.5 soot dust granule after charged to flow through from the positive plate mesh that gathers dust, this makes the PM2.5 soot dust granule after charged, can obtain all closely and the positive plate touch opportunity of gathering dust, so, the radius 0.01m that the maximum distance r of the PM2.5 soot dust granule after charged and the positive plate that gathers dust is hole, so r2=is 0.012=0.0001
We,, with this, contrast former old-fashioned electric cleaner, and r is 0.2m so, r2=0.22=0.04,
So 0.04/0.000 1 ﹦ 400, can adsorb coulomb like this gravitation f and improve 400 times.If the mesh diameter of new-type screen mesh type positive plate is designed to 0.008 m, manage again to force the PM2.5 soot dust granule after charged to flow through from the positive plate mesh that gathers dust, this makes the PM2.5 soot dust granule after charged, can obtain closely and the positive plate touch opportunity of gathering dust, so, the radius 0.004m that the maximum distance r of the PM2.5 soot dust granule after charged and the positive plate that gathers dust is hole, r2=is 0.0042=0.000016
We,, with this, contrast former old-fashioned electric cleaner, and r is 0.2m so, r2=0.22=0.04,
So 0.04/0.000016 ﹦ 2500, can adsorb coulomb like this gravitation f and improve 2500 times.This is equivalent to the charged ability of PM2.5 soot dust granule, improves and increases by 2500 times! Therefore, although it is constant to be less than the amount of charge of PM2.5 micron order aerosol smokeshade, obtain a coulomb absorption gravitation, because reducing greatly and improve apart from r! Therefore, be less than the charged smokeshade of PM2.5 micron order aerosol, can be efficiently trapped by screen mesh type positive plate.
Beneficial effect of the invention Shi ﹕
1. this technology, the coulomb absorption gravitation of the charged particulate that is less than PM2.5 of raising that can thousands of times to screen mesh type positive plate, therefore, is less than PM2.5 micron order aerosol smokeshade, can efficiently be trapped by screen mesh type anode plate,
2. screen mesh type anode plate, lightweight, simple in structure, be convenient to make, convenient installation, cost is low, is beneficial to again deashing Chun and beats.Therefore, be applicable to rapid large scale application, be especially applicable to the electric cleaner that transformation is moving at present, as long as this technology of application, transformation is one to two electric field wherein, just can make to transform the smoke dust discharge concentration of rear electric cleaner, from hundreds of mg/Nm
3be reduced to 0.01 mg/Nm
3below, can directly reach country-level standard air!
3. this technology is applicable to the large, medium and small electric cleaner of various uses.With absolute predominance, in the industries such as metallurgy, cement, boiler of power plant and chemical industry, be used widely.
