Drying furnace for producing low-water-content potassium fluoride

Abstract

The drying furnace is spherical and comprises an inner shell, an outer shell, a feeding pipe, a discharging pipe, a heat source and spray heads, the inner shell and the outer shell are arranged in parallel in a spaced and sleeved mode, the heat source is longitudinally arranged in the middle of the interior of the inner shell, and the multiple spray heads are arranged in a circumferential array mode along the middle of the inner wall of the inner shell; the middle of the feeding pipe is fixedly arranged on the outer shell in a sealed mode, the end, located in the outer shell, of the feeding pipe communicates with the sprayer, the discharging pipe is vertically arranged in the center of the bottom of the inner shell, the upper end of the discharging pipe fixedly communicates with the inner shell, and the lower end of the discharging pipe downwards extends out of the outer shell. The drying furnace aims at solving or at least relieving the problems that potassium fluoride produced through an existing technology is high in water content, prone to being affected with damp, not easy to transport and store and low in activity, and the drying furnace for producing the low-water-content potassium fluoride is provided.

Description

technical field [0001] The invention relates to the technical field of potassium fluoride production, in particular to a drying furnace for the production of potassium fluoride with low moisture content. 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; can be used as welding flux, insecticide, catalyst, absorbent, etc.; can also be used as analytical reagent, complex former; or fluorine as an organic compound chemical agent. [0003] Potassium fluoride is white monoclinic crystal or crystalline powder, salty 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] The potassium fluoride produced by the current process has a high water content, is not only susce...
