Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrolytic cell cover, concretely relates to a kind of electrolytic cell cover positioning device and its anti-corrosion treatment system. BACKGROUND

[0002] The nitrogen trifluoride electrolytic cell includes a cell body and a cell cover. The cell body is composed of an anode chamber, a cathode chamber and an electrolytic cell. The material of the electrolytic cell cover is ordinary carbon steel. This material has low cost, but it has weak resistance to hydrogen fluoride corrosion. In the electrolysis reaction, the gas generated by the anode and cathode will carry out the hydrogen fluoride in the electrolyte, thereby corroding the electrolytic cell cover.

Usually, manual operation is used for the transportation, positioning and anti-corrosion treatment of the electrolytic cell cover.
