Abstract
The invention relates to a silver electrolysis acid mist collecting device, which comprises a silver electrolysis cell (1), an absorbing cover (2) and a waste gas lead-out pipe (3), wherein the absorbing cover (2) is positioned over the notch of the silver electrolysis cell; four edges on the notch of the silver electrolysis cell are over against peripheral side flanges of the cover body of the absorbing cover (2) respectively, and are formed in parallel at equal intervals; transparent glass blocking surfaces (4) are formed between the edges of the notch of the silver electrolysis cell and the side flanges of the absorbing cover; and the lower parts of the transparent glass blocking surfaces on the feeder bus direction side and the discharging hole direction side of the silver electrolysis cell (1) are provided with gas return windows (5). According to the device, the installed capacity of induced air suction equipment can be lowered greatly, power energy is saved, and nitrogen oxide-containing waste gas is collected efficiently simultaneously.
Description
Technical field
The invention belongs to technical field of environmental protection facilities, particularly a kind of silver-colored electrolyzer acid mist collection device.
Background technology
At present, will produce nox contained waste gas inevitably in the silver-colored electrolytic process in the smelting industry, so these potrooms all to be provided with the acid mist treatment system.The acid mist that produces in the electrolyzer is collected and handled, after the concentration reduction with obnoxious flavour, enter atmosphere just now, reduce pollution environment with this.But it is the sky in whole workshop to be concentrated aspirate that existing acid mist is collected, and the air inducing pumping equipment must have enough power capacity, could effectively collect acid mist.Therefore existing nox contained waste gas treatment unit efficient is lower.
Find through retrieval:
On February 24th, 2010 Chinese utility model Granted publication CN 201411497Y; A kind of " totally enclosed silver electrolyzer " disclosed; Include cell body, negative plate and positive plate in the electrolyzer are set, are used for the scraper transmission mechanism of the anticathode plate busbar that energising is connected with positive plate, scraper, band transmission rod; On electrolyzer, be provided with sealing cover sealed electrolytic cell open section, the gas sampling mouth is set on sealing cover.This utility model is used for solving the exhaust emission environment that produces at electrolytic process; But because system is in full full closeding state, the exhaust gas discharging collection effciency is low.
On April 27th, 2011, Chinese utility model Granted publication CN 201809455 U disclosed a kind of aluminium electrolysis cell cover plate for sealing device, and this seal apparatus comprises retaining head on groove cover plate for sealing bar, the groove cover plate, groove cover plate retaining head, aluminium sheet U type groove and insulation U type groove down.Figure of description by this patent can draw, the size of groove cover plate and gas skirt identical with cell dimension and over against, promptly the four edges on the electrolyzer notch along respectively at absorb the cover cover body around the side shield limit face.This utility model also is to be used for solving the exhaust emission environment that produces at electrolytic process; Same because system is in full full closeding state, the exhaust gas discharging collection effciency is low.
In view of above-mentioned present situation, be necessary to explore suitable treatment unit, the technical scheme that the present invention will introduce below produces under this background.
Summary of the invention
The object of the invention is to solve the problems referred to above that prior art exists, and a kind of silver-colored electrolyzer acid mist collection device is provided; Can reduce the installed capacity of air inducing pumping equipment greatly, practice thrift power source, simultaneously nox contained waste gas realized the high-level efficiency collection.
Task of the present invention is accomplished like this, a kind of silver-colored electrolyzer acid mist collection device, and it comprises silver-colored electrolyzer, absorbs cover, waste gas fairlead; Absorbing cover is positioned at directly over the silver-colored electrolyzer notch; Four edges on the silver electrolyzer notch along respectively with absorb the cover cover body around the side rib face and parallel equidistant one by one; Between silver electrolyzer notch edge and the absorption cover side rib transparent glass block face is housed; Wherein the return-air window is all left in the transparent glass block face bottom of the power lead direction side of silver-colored electrolyzer and discharge port direction side.
To silver-colored electrolytic cell operation, described transparent glass block face is divided into the polylith splicing for the ease of electrolysis process, the unlatching guide rail that has up and down push-and-pull relatively to slide between piece and the piece.
Silver-colored electrolysis acid mist collection device of the present invention makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1, owing to concentrate overhead the collection to be distributed to the space that the overhead transparent glass block face of each silver-colored electrolyzer is surrounded the acid mist in whole workshop, can reduce the installed capacity of air inducing pumping equipment greatly, practice thrift power source.
2, stay the return-air window in the power lead direction side of silver-colored electrolyzer and the transparent glass block face bottom of discharge port direction side; Can realize the spatial acid mist that the overhead transparent glass block face of silver-colored electrolyzer is surrounded is evenly collected; Can alleviate the interference that adjacent absorption cover produces the strong convection negative pressure, realize nox contained waste gas is realized the high-level efficiency collection.Simultaneously, this technical characterictic is not the common practise of this area.Technical scheme of the present invention possesses substantive distinguishing features and progress.
3, the technical scheme that the present invention introduced reclaims owing to nox contained waste gas being handled the resulting SODIUMNITRATE in back, thereby both can embody recycling economy, can avoid secondary pollution again; Whole apparatus structure is simple, easy to operate.
Description of drawings
Fig. 1 looks synoptic diagram for master of the present invention.
Fig. 2 is a schematic side view of the present invention.
