Ammonia fog collection and treatment system for electrolysis workshop

Abstract

The invention belongs to the technical field of recovery of waste gases and relates to an ammonia fog collection and treatment system for an electrolysis workshop. The system comprises a cell face ammonia fog collection mechanism and an ammonia fog treatment mechanism, the cell face ammonia fog collection mechanism comprises a gas collection device, an exhaust branch, an exhaust main pipe, an electrolysis area, idler wheels and rails, the ammonia fog treatment mechanism comprises an ammonia washing tower, a centrifugal fan and a chimney, the gas collection device comprises a gas collection hood group, the gas collection hood group comprises 2-5 gas collection hoods, the gas collection hoods are installed in the rails in the electrolysis area through the idler wheels, and the adjacent gas collection hoods in the gas collection hood group have the height difference. By using the system, the gas collection hoods can be pushed and moved, and are mutually stacked and an electrolytic cell face is exposed, then a worker operates conveniently, or the gas collection hoods are pushed, moved and unfolded to cover the whole cell face, the waste gas produced in the electrolysis workshop is effectively collected, the gas collection efficiency is high, and the treatment effect is good.

Description

Technical field

[0001] The invention belongs to the technical field of waste gas recovery and relates to an ammonia mist collection and treatment system in an electrolysis workshop. Background technique

[0002] The neutral solution for electrolytic manganese production is MnSO 4 , (NH 4 ) 2 SO 4 , H 2 In the mixed solution of O, ammonia is added to adjust the pH value during the electrolysis process, and the ammonium ion in the electrolyte is hydrolyzed, and ammonia gas will be released, which will react with water at a certain height on the tank surface to form a mixed ammonia mist. Due to the large area of ​​the electrolysis area in the electrolysis workshop and the complex electrochemical reaction, all the electrolysis workshops of manganese metal plants at home and abroad adopt the method of disorganized discharge, which makes the workshop smell obvious. So far, there has been no better solution. . Summary of the invention

[0003] The purpose of the present invention is to ...
