Background technology
Wet cottrell is a kind of for processing the cleaning equipment containing trace dust and microparticle, is mainly used to remove Containing harmful substances such as the dust in humid gas, acid mist, drop, aerosol, PM2.5, have that efficiency of dust collection is high, the pressure loss is little, Behaviour do simple, energy consumption is low, movement-less part, without reentrainment of dust, be operable with below flue gas dew point temperature, can control with other flue gas Reason equipment combines, the advantage such as versatile and flexible, is one of the ideal equipment of industrial smoke pollution control, in each industrial processes Deacidify, except mist has extensive application.In particular with the deterioration increasingly of China's atmosphere quality, Environmental Protection in China situation is day by day Severe and national environmental standard day by day strict, nearly 2 years, wet static dedusting technology was at China's coal-fired plant boiler flue gas With wet desulfurizing process cooperative disposal in governing system, efficiently removing a large amount of SO3 blue smokes acid produced because of wet desulphurisation system The application of the aspects such as the heavy metal in mist, gypsum rain and flue gas is in multiplication trend.
The ultimate principle of wet cottrell is similar with dry electrostatic cleaner with work process, is divided into charged, receipts Collection and deashing three phases, different is only its purge mode difference.It is different from the side of dry electrostatic cleaner vibration dust-cleaning Formula, wet cottrell uses the mode that current rinse, makes pollutant remove along with the flowing of cleanout fluid.
At present, domestic horizontal wet electrostatic precipitator main flow pole plate form mostly is slab construction, maximum the lacking of this pole plate Fall into is the rinse water easily bifurcated because of action of gravity impact, it is difficult to form uniform moisture film at polar board surface, especially pole plate with Height to increase, occur that moisture film is uneven, cleaning performance is not good enough.For the problems referred to above, it is necessary to propose a kind of new wet electrostatic The technical scheme of cleaner unit.
Utility model content
The purpose of this utility model is to provide a kind of novel wet cottrell, and this wet cottrell need not spray Mouth discharges into row spray deashing from top to anode, can guarantee that again that on positive plate, moisture film is uniform simultaneously, improves flush efficiency, and clean Water is without electric field region, it is ensured that electric field is stable, it is to avoid the taking out of of drop, thus improves dust-collecting efficiency.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of wet cottrell, it by negative electrode spray water tank, anode spray water tank, high voltage power supply A, high voltage power supply B, Anode cleans pipe, penthouse, cathode hanger, cathode top shower nozzle A, cathode top shower nozzle B, cathode top framework A, cathode top frame Frame B, import uniform board, outlet uniform board, import loudspeaker, outlet loudspeaker, anode row, cathode line A, cathode line B, under(-)chassis A, Under(-)chassis B, shell of dust remover, base plate blow-off pipe, anode spray blowdown apparatus and hot air apparatus composition, it is characterised in that anode The rinse water of row is cleaned pipe by anode and is arrived shower, and rinse water arrives positive plate table after the outer surface of shower is uniform Face, forms uniform water film, is provided with anode spray blowdown apparatus, subregion before and after wet cottrell employing in the end of shower Power supply, and front and back subregion uses the cathode line of different discharge performance.
Described anode row be made up of entablature, lid, shower and positive plate, and anode rinse water is cleaned pipe by anode and arrived Reaching shower, the top of shower is evenly equipped with spray apertures, and rinse water arrives the lower surface of lid, Jing Guo by spray apertures injection Current-sharing falls back to the outer surface of shower, and the outer surface of shower keeps certain roughness, and the cross section of lid can be V Shape, circular arc, polygon etc..
Described positive plate is double-deck tympanites plate structure, is made up by welding of two block plates, " recessed in Double-layer symmetrical after molding Convex " drum balloon-shaped structure, its peripheral sealing welds, and surface solder joint is staggered in center in rows and columns, is uniformly distributed.
Described anode spray blowdown apparatus structure be by shower extend be connected to outside cleaner unit, in short tube end equipped with Threeway, is provided with pipe plug in threeway end, in threeway bottom equipped with valve, is arranged right below water receiving tank at valve.
Described wet cottrell use before and after switched-mode power supply, during proparea negative electrode spray, back zone do not stops power supply, continues Work, during back zone negative electrode spray, proparea do not stops power supply, works on, it is ensured that cleaner unit continuous and steady operation, and front and back district adopts With the polar curve of different discharge performances, proparea uses the long tooth prickle wire that discharge performance is strong, and back zone uses the short tooth that electric field intensity is high Prickle wire.
The typically saturated dampness of flue gas that described wet cottrell processes, it is easy at the insulator of cathode hanger device Upper condensation, causes electric field short circuit, and insulator damages, and cleaner unit cannot be properly functioning, and hot air apparatus send to negative electrode swing pipe device continuously Hot blast, it is ensured that the insulator of cathode hanger device will not condense.
The utility model has the advantages that owing to wet cottrell need not discharge into anode from anode top with nozzle Row spray deashing, can guarantee that again that on positive plate, moisture film is uniform, is arrived after the outer surface of shower is uniform by rinse water simultaneously Positive plate both side surface, forms the uniform fold of moisture film, improves cleaning performance.Being extended by shower is connected to outside cleaner unit, logical Cross blowoff valve to carry out periodical blowdown and solve the blockage problem of spray apertures.Switched-mode power supply before and after employing, it is ensured that cleaner unit is continuous Electrically continuous stable operation, simultaneously before and after subregion use the cathode line of different discharge performance, thus improve efficiency of dust collection.
Below in conjunction with the accompanying drawings this utility model is described further.
