Abstract

The invention belongs to the technical field of electrolytic fluorine production, and particularly relates to an automatic control device for hydrogen fluoride supply. The device comprises a first stop valve 1, a mass flow meter 2, a second stop valve 3, a third stop valve 4, a fourth stop valve 5, a first pneumatic valve 6, a fifth stop valve 7, a sixth stop valve 8, a second pneumatic valve 9, aseventh stop valve 10, a third ball valve 11, a second electromagnetic valve 12, a first ball valve 14, a first electromagnetic valve 15, a second ball valve 16, a first electrolytic cell 171, a second electrolytic cell 172 and a DCS automatic control module 18. By using the device, the loss of a hydrogen fluoride material can be reduced, the process parameter stability of the electrolytic cellscan be improved, and the acidity can be stabilized within the range of 38-42%. The service life of the carbon plates of the electrolytic cells can be prolonged by more than 30-50%. Continuous feedingof the electrolytic cells can be realized.

Description

technical field [0001] The invention belongs to the technical field of electrolytic fluorine production, and in particular relates to an automatic control device for feeding hydrogen fluoride. Background technique [0002] In the field of electrolytic fluorine production, there are two main technologies for hydrogen fluoride feeding: centralized and individual feeding. In production practice, conventional selection (gas phase or liquid phase centralized feeding and separate feeding) is used to achieve the purpose of material balance and stable operation during the operation of the electrolyzer. [0003] Among the above methods, the AHF centralized feeding material measurement is difficult, and the stable operation control is difficult, but the number of centralized feeding equipment is small, and the material centralized safety factor is large, which is most suitable for automatic control. [0004] In conventional industrial production, the AHF centralized feeding of the el...
