Abstract
The invention relates to a dust removing device used for collecting industrial smoke, in particular to a string wind type dust remover. The string wind type dust remover is suitable for upgrading of an old electric precipitator technology, and after an old electric precipitator is upgraded, under the condition that original technical parameters of the old electric precipitator are not changed, pm 2.5 micron-grade aerosol smoke particles can also be efficiently gathered.
Description
Technical field
The present invention and a kind of dust arrester for collecting industrial fumes, it is especially suitable for transforming with old electric cleaner technology upgrading, in the case of its technical parameter is immovable, by string wind formula cleaner unit technology, after old Retrofit on electrostatic precipitator can be made, can be to pm2.5 micron order aerosol smokeshade, a kind of string wind formula cleaner unit efficiently trapped.
Background technology
Known, the various cleaner units of current all domestic and international application, all can not be collected less than PM2.5 micron order aerosol smokeshade in industrial fumes, cause less than PM2.5 micron order aerosol smokeshade, be all discharged in air！Become the main contributor of haze terrible disaster today, cause environment for human survival severe exacerbation！Now, the bottom line of substantially surviving in the haze sky of normalization, the serious threat mankind！Therefore, the cleaner unit draining technology of below PM2.5 harmful substance granule is thoroughly stopped！It has been the great demand of society.
nullAt present，The emission concentration standard of China's industrial fumes has improved to 30mg/Nm，The existing a large amount of old formula electric cleaner being currently running，All will be faced with new round technology upgrading transformation，Existing electrostatic precipitation technology，It is difficult to ensure that reach below 30mg/Nm after Gai Zao，Even if after Gai Zao，Cleaner unit concentration of emission can reach standard 30mg/Nm，But there is no to limit the discharge of PM2.5 micron order aerosol smokeshade，PM2.5 still can absolutely be discharged in air，If really thoroughly to solve this mankind's haze calamity，The emission concentration standard of industrial fumes must improve to below 0.1mg/Nm，This could thoroughly stop the discharge of PM2.5 micron order aerosol smokeshade，Therefore，This just need to create the technology of renewal，Make improved electric cleaner，To below PM2.5 micron order aerosol smokeshade，Can the most effectively trap.
Summary of the invention
In order to overcome existing electric cleaner, to below pm2.5 micron order aerosol smokeshade in industrial fumes, it is impossible to efficiently trap and wretched insufficiency that other are various.
It is an object of the invention to provide and a kind of there is the relatively low string wind formula electric cleaner of simple in construction, construction difficulty relative requirement and manufacture method thereof.
The present invention solves technical problem and be employed technical scheme comprise that.
One, the positive plate that gathers dust having in the old-fashioned electric cleaner of N number of electric field is all removed with corona prickle wire, coordinate with corona prickle wire with the positive plate that gathers dust of the open type combination type dust collecting anode board old-fashioned shield type of replacement again, at a certain distance, alternately longitudinal arrangement combination is mounted to the big electric field that gathers dust of flow-through, redesign the slanted channel by flue gas is arranged through one jiao, casing end from air inlet (1) and enter electric field, enter the flue gas of electric field, can be forced repeatedly to pass from the gap of open type combination type dust collecting anode board (2), flue gas after being cleaned, the most configured slanted channel at diagonal angle is arranged from air port (4).Due to charged micron order aerosol smokeshade, can obtain and gather dust positive plate closely chance, because of the Coulomb force of charged micron order aerosol smokeshade be with distance square become anti-this, (f=k Q .Q/r) so, owing to r distance substantially reduces, the Coulomb force that can make charged micron order aerosol smokeshade obtains hundreds times and improves, and this makes smokeshade, it is thus achieved that the chance being captured more times.Thus, make below pm2.5 micron order aerosol smokeshade, can efficiently be captured.
Two, neoteric string wind formula electric cleaner, changes the air-flow trend of former old-fashioned cleaner unit, makes flue gas no longer pass in a linear fashion from electric field, but the most diagonally flow, thus, make flue gas in the confined space, it is thus achieved that pass through electric field distance.Root Ju hooks stock string theorem: hook side adds stock side equal to string side, so, tangential air flow all be increased with the time by the electric field distance in the confined space, and this makes micron order aerosol smokeshade charged for below pm2.5, it is thus achieved that the more sufficient time is captured with more chances.
nullThree、It is of importance that flow to owing to flue gas changes，By former longitudinal flow，Change into horizontal and double oblique pass through electric field，This makes electric field basal area，By original lateral calculations，Change longitudinal calculating into，The electric field basal area longitudinally calculated，Because domestic general old-fashioned electric cleaner is typically all three to five electric fields，It is significantly larger than lateral calculations electric field basal area，Typically all can increase by more than two to three times，Practical experience according to old-fashioned electric cleaner teaches that: when electric field basal area often doubles，Wind speed in electric field can reduce half，And wind speed often reduces half，Its efficiency of dust collection will improve ten times，This means that，If originally the concentration of emission of electric cleaner industrial fumes is 200mg/Nm，In the case of its technical parameter is immovable，After being transformed by string wind formula electric cleaner technology，The concentration of emission fall end not only can be made to below 20mg/Nm，And under conditions of again owing to using open type combination type dust collecting anode board technology.This can make the Coulomb force of charged micron order aerosol smokeshade obtain hundreds times raising, experiment proves, the concentration of emission of improved electric cleaner industrial fumes, fully achieve below 0.1mg/Nm, this just makes electric cleaner from invention one over 100 years, obtains the discharge function thoroughly having stopped micron order aerosol smokeshade charged for below pm2.5 for the first time.
The beneficial effect of the invention is 1. string wind formula electric cleaners, that dust-cleaning principle is constant, dust collecting process parameter constant, electric cleaner shell structure are constant, pole plate and cathode line put in order is constant, anode-cathode distance magnitude of voltage constant, applied is constant, even deashing shake mode also can be constant, only with open type combination type dust collecting anode board, substitute the positive plate that gathers dust of old-fashioned shield type, being changed by flue gas flow direction, after just can making transformation, electric cleaner obtains the discharge function thoroughly having stopped micron order aerosol smokeshade charged for below pm2.5 again.Its concentration of emission directly reaches below 0.1mg/Nm.This makes to have continued an old-fashioned electric cleaner over 100 years, after putting into the melting pot specifically, is the most really provided with the power of dedusting.
2. string wind formula electric cleaner, simple in construction, cost are low, only use several passage, just can substitute over tens passages, although number of channels greatly reduces, but therefore specific collection area reduces, minimizing due to passage, not only save equipment cost, also reduce corona operating cost, operating cost be only its 1/3rd).
3. string wind formula electric cleaner, is particularly suited for the large, medium and small air quantity industrial electro cleaner reform of various uses, can obtain wide popularization and application in the every profession and trades such as fire coal, metallurgy, cement, boiler of power plant and chemical industry.
