In order to guarantee that the electrolytic solution Volatile Gas gets into ventilation system, install the high 10mm of median septum ventilation opening, wide 835mm, and the present position is than the high 10cm of liquid level of electrolyte.
In order to guarantee electrolysis liquid surface at settling position, on electrolyzer, establish the electrolytic solution riser, when electrolyte content was big, electrolytic solution can go out electrolyzer from the overflow of electrolytic solution riser, is recycled again.
In order to have guaranteed that airshed is basic identical between each dividing plate, the suction opening of every adjacent two Class A hollow shelf casees and Class B hollow shelf case is on relative position.
Sour Volatile Gas intensification cleaning device in the described silver-colored electrolytic process, the manufacturing materials system of electrolyzer and ventilation system all adopt not can be by acid electrolyte corrosive material, thereby can not cause electrolytic solution and finished product silver powder contaminated.
The advantage of the utility model is:
1, to adopt electrolyzer and ventilation system be the mechanism of one to the utility model, take up space little, do not influence tankage, look into necessary work in electrolytic process such as groove.
2, behind the described device of use the utility model, reduced evaporable acid mist in 90% electrolytic process, operating environment improves greatly.
3, behind the described electrolyzer of use the utility model, original ventilation system is that the factory building exhaust fan will be cancelled, and has avoided noise pollution.
4, can utilize through handling after the electrolytic solution Volatile Gas is recovered, 330 days=13200 kilograms of annual recyclable approximately nitric acid 40 kg/day * reduce the wasting of resources again.
5, after uncooled electrolytic solution Volatile Gas was handled through scavenging tower in the air channel, sour gas was neutralized the back discharging, has alleviated N0x gas to atmospheric pollution.
6, all adopt not can be by acid electrolyte corrosive material for electrolyzer and ventilation system, thereby can not cause electrolytic solution and finished product silver powder contaminated.
