Technical Field
The invention relates to the technical field of chemical industry, in particular to a novel hydrochloric acid recovery device for antimony smelting by ore pulp electrolysis.
Background
The electrolytic antimony smelting process with ore pulp is a brand new antimony smelting process, and combines the three procedures of raw ore leaching, solution purification and electrodeposition into one whole. In the electrolytic bath, the ore is leached by using the anode reaction in the electrodeposition process, and the metallic antimony is separated out from the cathode. In the energized state, a series of reactions occur near the cathode and anode and within the cell. The existing ore pulp electrolytic tank is an open cuboid tank, and a series of reactions occur in the tank to release heat, so that the temperature of a solution in the tank is kept at about 55 ℃. The solution in the tank is hydrochloric acid with certain solubility, and the hydrochloric acid has volatility, and the volatilization of the hydrochloric acid is aggravated by the heat released by the reaction in the tank. The volatilization of the hydrochloric acid causes the acidity in the solution to be reduced, and the consumption of the hydrochloric acid is increased; secondly, certain pollution to the atmosphere is caused; and thirdly, corrosion to workshop equipment is caused.
