Abstract

The invention relates to the technical field of production of ammonium bifluoride and in particular relates to an ammonium bifluoride mother solution cooling system. The ammonium bifluoride mother solution cooling system comprises a circulating groove, an air cooling tower, crystal growing grooves, a solid-liquid separator and a mother solution groove, wherein the bottom part of the air cooling tower is communicated with an inlet of the circulating groove; the bottom of the circulating groove is communicated with the upper end of the air cooling tower and the upper ends of the plurality of crystal growing grooves through a first centrifugal pump respectively; the bottoms of the plurality of crystal growing grooves are communicated with a centrifugal machine through a second centrifugal pump; the centrifugal machine is connected with the solid-liquid separator; a liquid outlet of the solid-liquid separator is connected with the mother solution groove; a solid outlet of the solid-liquidseparator is connected with the circulating groove. The ammonium bifluoride mother solution cooling system has the advantages of high cooling efficiency and good cooling effect; zero emission of wasteliquid and waste dreg can be realized in a cooling process and waste gas is discharged after reaching the standards.

Description

technical field [0001] The invention relates to the technical field of ammonium bifluoride production, in particular to a cooling system for ammonium bifluoride mother liquor. Background technique [0002] Ammonium bifluoride is a corrosive chemical with the formula NH 4 HF 2 , its aqueous solution is weakly acidic, can dissolve glass, slightly soluble in alcohol, easily soluble in cold water, and very easy to deliquescence. Ammonium bifluoride can corrode glass and is corrosive to skin. It can be used as chemical reagent, glass etchant, disinfectant and antiseptic in fermentation industry, solvent for metal beryllium made of beryllium oxide and surface treatment agent for silicon steel plate. It is also used in manufacturing Cleaning and descaling of ceramics, magnesium alloys, boiler feed water systems and steam generation systems, and acid treatment of sandstone in oil fields. It can also be used as catalyst components for alkylation and isomerization. Cast steel, wood...
