Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical refining equipment, in particular to an electrolytic cell for electrolytic zinc production. Background Art

[0002] Zinc electrowinning refers to the metallurgical process of electrolytically extracting zinc using zinc sulfate aqueous solution as the electrolyte, also known as zinc electrolysis. The zinc electrolytic cell is one of the core equipment used for zinc electrolysis. The electrodes in the zinc electrolytic cell are usually arranged in an alternating pattern, that is, a row of anodes and a row of cathodes are arranged alternately. When the electrolytic cell is working, the current transmitted through the electrodes will dissolve the zinc metal on the anode into zinc ions, which are deposited on the cathode to form a zinc plate.

[0003] The existing liquid inlet and outlet methods of the electrolytic cell are top-in-top-out or bottom-in-top-out. In order to suppress the generation of sulfuric acid mist and volatile gases during the electrolysis process, additives must be added during the electrolysis process to cover the liquid surface with foam generated by the additives. However, the top-in-bottom-out liquid inlet method can easily cause the local acid-zinc ratio to be out of control, thereby reducing the electrolysis efficiency. Utility Model Content
