Abstract

The invention relates to the technical field of new liquid purification and impurity removal equipment for electrolytic nickel, and discloses an electrolytic nickel purification and impurity removal reaction tank and method. The purification and impurity removal reaction tank comprises a tank body, a tank cover and a flow guide device; a bottom air pipe is arranged at the lower end of the tank body; a liquid inlet and a liquid outlet are formed in the side surface of the tank body; the tank cover is used for sealing an upper opening of the tank body; the top of the tank cover is provided with a ventilation opening, a chlorine adding pipe, a reagent adding opening and a detection opening; the chlorine adding pipe extends into an inner cavity of the tank body by two thirds of the depth, and a pH / ORP tester is mounted at the detection opening; the flow guide device comprises a flow guide cylinder which is vertically mounted in the inner cavity of the tank body, and the upper end of the flow guide cylinder communicates with the liquid outlet; and the bottom air pipe, the ventilation opening, the liquid inlet, the liquid outlet, the chlorine adding pipe and the reagent adding opening are all provided with automatic adjusting valves. According to the electrolytic nickel purification and impurity removal reaction tank and method, high-efficiency impurity removal can be carried out in a large-flow high-impurity system, and pure electrolytic cathode liquid is obtained.

Description

technical field [0001] The invention relates to the technical field of new liquid purification and impurity removal equipment for electrolytic nickel, in particular to an electrolytic nickel purification and impurity removal reaction tank and a method thereof. Background technique [0002] In the nickel-cobalt hydrometallurgy industry, three methods are usually used to produce electrolytic nickel: one is to produce electrolytic nickel by soluble anode diaphragm electrolysis process, the other is to use sulfate electrowinning process, and the third is to use chloride electrowinning process. These three processes have their own advantages and disadvantages. Among them, the soluble anode diaphragm electrolysis process adopts the classic three-stage purification technology to remove impurities and purify the solution through neutralization and hydrolysis to remove iron, replace copper deposition, and chlorine gas oxidation to remove cobalt. The purity of the new solution after p...
