Abstract

The invention relates to auxiliary equipment for electrolytic deposition in the technical field of chemical engineering, belongs to the technical field of environmental protection, and specifically relates to an acid mist recovery system device. The system device includes a cathode frame and an anode frame arranged in the electrowinning tank. The system also includes an acid mist absorption tower. An exhaust channel is set on the storage tank, and each exhaust channel is connected with the acid mist outlet on the anode frame, and the generated acid mist passes through the exhaust channel connected with the acid mist outlet, and enters the acid mist absorption tower under the action of the exhaust fan to process. The device changes the bad environment caused by the direct unorganized discharge of the acid mist generated in the electrowinning process in the old electrowinning device. The ventilation equipment adopts negative pressure ventilation to save resources. Avoid using a gas collecting hood to extract acid mist, which will cause the liquid formed on the gas collecting hood to drip onto the copper bar or copper rod, which will corrode copper and affect the quality of nickel products.

Description

technical field

[0001] The invention relates to auxiliary equipment for electrolytic deposition in the technical field of chemical engineering, belongs to the technical field of environmental protection, and specifically relates to an acid mist recovery system device. Background technique

[0002] The principle of electrolytic nickel:

[0003] Cathodic nickel is electrolytically deposited from an aqueous solution of pure nickel salt using an insoluble anode. Electrowinning of sulfate solutions usually uses lead anodes, while chloride solutions use stable anodes, such as graphite anodes and titanium anodes.

[0004] The anode is electrolytically deposited in pure sulfuric acid solution, and the process is mainly oxygen evolution.

[0005] h 2 O-2e=1 / 2O 2 +2H +

[0006] When a new pb anode is used for electrolysis, before the oxygen evolution reaction occurs, the dissolution of the pb anode also occurs, but the PbSO 4 It also has a certain solubility in the sulfate elec...
