Embodiment 1

[0036] Such as Figure 1-5 Shown, a kind of large particle potassium fluoride production technique comprises the steps:

[0037] S1, batching, 48% KOH lye and HF acid solution are stirred and neutralized in the reactor to obtain a KF solution, and the obtained KF solution is input into a settling tank and left to stand;

[0038] S2, adjust, input the KF solution after standing in step S1 into the production tank, and accurately adjust the pH value of the KF solution;

[0039] S3, drying, the KF solution adjusted in step S2 is pumped into the spray gun 2 on the top of the drying tower, the feed rate of the KF solution and the air pressure in the drying tower are adjusted, and the KF solution is dried to obtain large particle potassium fluoride.

[0040] In described step S1, KOH lye is first input into the reaction kettle, the liquid level of KOH lye is higher than the HF acid outlet of the reaction kettle, and then the stirring is started, and the HF acid is slowly added into...

Abstract

The invention relates to a production process of large-particle potassium fluoride. The production process comprises the following steps: S1, burdening; S2, adjusting; and S3, drying. The invention aims to solve or at least alleviate the problems of small particles, fast moisture absorption, short storage time, easy caking and difficult long-distance transportation of potassium fluoride produced by the existing process, and provides a production process of large-particle potassium fluoride.

Description

technical field [0001] The invention relates to the technical field of potassium fluoride production, in particular to a large particle potassium fluoride production process. Background technique [0002] Potassium fluoride is an inorganic salt, so it is also called potassium fluoride salt. Potassium fluoride can be used for glass engraving, food preservation, electroplating; it can be used as welding flux, insecticide, catalyst, absorbent, etc.; it can also be used as analytical reagent, complex forming agent; or as fluorine of organic compounds agent. [0003] Potassium fluoride is white monoclinic crystal or crystalline powder, salty in taste and easy to absorb moisture. Soluble in water, insoluble in ethanol. Its aqueous solution is alkaline and can corrode glass and porcelain. The relative density is 2.454, and the melting point is 858°C. [0004] Potassium fluoride produced by the current process has small particles, fast moisture absorption, short storage time, e...
