Abstract
The utility model discloses an electrolytic aluminium smoke purification and material feeding apparatus, comprising a flue, a pneumatic chute, and a sealed material feeding box. The sealed material feeding box is connected on the pneumatic chute. A valve and an air-delivery duct are connected at the bottom of the sealed material feeding box. More than three material feeding pipes with different length are connected on the sealed material feeding box. The material feeding pipes are 3-6 roots. A material feeding by-pass pipe is connected on the sealed material feeding box, an induction proximity transducer is installed inside the sealed material feeding box, and a filter screen is arranged inside the sealed material feeding box. The utility model has the advantages that the utility model can make alumina containing fluorine and smoke be equably mixed, and can enhance the purification efficiency of the smoke, etc.
Description
Technical field:
The utility model relates to the feeding device that a kind of electrolytic aluminum smoke purifies.
Background technology:
Prebaked cell for aluminum-reduction can produce nuisance (fluorochemicals 16～25Kg/t.Al) such as fluorochemical in process of production, adopt flue gas dry cleaning technology in order to remove these nuisances, promptly use the raw materials for production aluminum oxide as sorbent material, nuisance gases such as hydrogen fluoride in the absorption flue gas, control fluorochemical quantity discharged, minimizing is to the pollution of surrounding environment, and the aluminum oxide after the absorption turns back in the production technique, directly reclaims fluorine.It is short that dry purification process has flow process, the purification efficiency height, and power consumption is low, and is reliable, non-secondary pollution, the characteristics of convenient operation and management can solve the smoke pollution problem of aluminium cell up hill and dale.Its technical process is: every electrolyzer flue gas pools together the sack cleaner that enters purification system by smoke discharging pipe, before entering sack cleaner, quantitatively add fresh aluminum oxide in the flue gas stream, mix with hydrogen fluoride gas in the flue gas by reactor, the all adsorbable hydrogen fluoride gas of aluminum oxide filtering layer on reactor and the filter bag, aluminum oxide after the absorption is collected by the sack cleaner filtering separation, through air-driven chute, handling equipments such as lift are delivered to bunker, the production of part electrolysis groove is used, a part turns back in the preceding flue of sack cleaner again mixes with hydrogen fluoride gas in the flue gas, make the abundant oxidized aluminium absorption of hydrogen fluoride gas, adopt the two-stage countercurrent adsorption technology, thereby guarantee higher purification efficiency.The degree of mixing of fresh aluminum oxide and fluoro-containing alumina and flue gas is the important factor that influences hydrogen fluoride gas adsorption cleaning efficient.Fresh aluminum oxide adds in the flue gas by reactor can obtain higher mixedness, and fluoro-containing alumina is directly to add in the preceding horizontal flue collector of sack cleaner, because flue gas purification system is a negative pressure system, so feeding device must be sealing, not influenced by negative pressure with the measuring apparatus that guarantees the feeding device front; In addition, flue gas flow rate higher (18～20m/s) in the flue, according to the production capacity of present domestic electrolysis of aluminum supporting flue gas purification system, the caliber of flue collector is greatly between φ 2500mm～φ 3500mm, fluoro-containing alumina directly adds by chute, just be difficult for evenly with mixing of flue gas, not only hydrofluoric purification efficiency is adsorbed in influence, and the cloth inequality also influences the dust-collecting efficiency of sack cleaner.
Summary of the invention:
The purpose of this utility model is to provide a kind of fluoro-containing alumina and flue gas of making to mix, to improve the gas cleaning feeding device of gas cleaning efficient, to solve the deficiencies in the prior art.
The utility model is achieved in that it comprises flue (1), air-driven chute (2), sealing feed box (3), sealing feed box (3) is connected on the air-driven chute (2), bottom at sealing feed box (3) is connected with valve (5) and steam line (6), is connected with filling tube different in size more than three (4) on sealing feed box (3); Filling tube (4) is 3～6; Be connected with reinforced bypass pipe (7) on the sealing feed box (3); In the sealing feed box (3) inductive proximity sensors (8) is housed; In sealing feed box (3), be provided with filter screen (9).
The utility model compared with prior art, because it is uniformly distributed to filling tube to fluoro-containing alumina by the sealing feed box, fluoro-containing alumina not only is subjected to the influence of horizontal gas flow in horizontal flue collector, also be subjected to the influence of gravity, rule by liquid motion, adopt three claw type filling tubes different in size to be " product " font fluoro-containing alumina is added flue collector, make material energy uniform distribution in flue collector, with the flue gas uniform contact, thereby improved the efficient of gas cleaning, therefore it has fluoro-containing alumina and flue gas are mixed, the advantage of raising gas cleaning efficient.
