Abstract

The invention discloses a method for cooling an inorganic molten salt. The method comprises the following steps: adding a molten inorganic liquid salt in a vessel into a bed formed by stacking of inorganic granular materials; and cooling the liquid salt on the bed with gas to form a solid salt. The method of the invention can well solve problems in cooling of liquid inorganic salts which has hightemperature and strong corrosivity, and is prone to sticking to a wall after solidification, especially problems in continuous cooling of industrial production; the method avoids usage of vessels forcooling of liquid inorganic salts, and thus avoids the problems of high temperature and strong corrosion and the problem of sticking of liquid inorganic salts to walls during cooling and solidification; and the method has the advantages of simple structure, safety, reliability, low cost and easy realization of industrial continuous production.

Description

Technical field [0001] Technical Field The present invention relates to a cooling of an inorganic salt, particularly relates to a method of cooling a molten inorganic salt. Background technique [0002] Chemical industry often produce large amounts of inorganic salts containing organic matter, it can not be directly used as industrial raw materials. There are lysed by the molten salt in which the organic material, in the molten salt has a high temperature, corrosive, and will adhered to the vessel wall, it is difficult to pour out from the container upon cooling to a solid. Prior art does not address the problem of cooling the molten inorganic salt such. Chinese patent CN205659976U, patents and patent CN106610220A in CN106608649A, involves cleavage using organic molten salt is heated, but did not disclose how the molten salt cooling liquid to a solid, and now is commonly used in industry for cooling the container using inorganic liquid, high temperature and strong corrosion is pr...
