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 [0001] The invention belongs to the technical field of environmental protection facilities, in particular to an acid mist collection device for a silver electrolytic cell. Background technique [0002] At present, waste gas containing nitrogen oxides is inevitably generated during the silver electrolysis process in the smelting industry, so these electrolysis workshops must be equipped with acid mist treatment systems. The acid mist generated in the electrolytic cell is collected and treated, and the concentration of harmful gases is reduced before being discharged into the atmosphere, thereby reducing environmental pollution. However, the existing acid mist collection concentrates on the air above the entire workshop, and the induced draft suction equipment must have sufficient power capacity to effectively collect the acid mist. Therefore, the efficiency of the existing nitrogen oxide-containing waste gas treatment device is relatively low. [0003] Searc...
