Salt washer, salt washing equipment and salt making system

Abstract

An embodiment of the invention provides a salt washer, salt washing equipment and a salt making system. The salt washer comprises a washing main body, a central pipe and a gas source. The washing mainbody comprises a washing cavity; and the washing cavity is provided with a washing liquid inlet and a salt slurry outlet. The inlet end of the central pipe is positioned above a clear liquid cavity,and the outlet end of the central pipe penetrates through the clear liquid cavity and extends into the washing cavity. The gas source is used for introducing gas into the washing cavity. According tothe salt washer disclosed by the invention, a mother solution containing high-concentration impurities on the surface of crystallized salt is replaced by washing liquid, a process of separating the impurities from the surface of the crystallized salt is accelerated by introducing gas into the washing liquid, and after salt slurry is washed by the salt washer in the invention, the salt slurry carrying a large amount of impurities is washed and purified, so that the quality of produced salt is improved.

Description

technical field [0001] The present application relates to the technical field of chemical industry, in particular to a salt washer, salt elutriation equipment and a salt making system. Background technique [0002] With the continuous improvement of high-salt wastewater zero-discharge industry requirements, the zero-discharge of high-salt wastewater has also developed from the early miscellaneous salt technology to the salt separation technology. Compared with traditional salt chemical production, high-salt wastewater often contains a large number of impurities, inorganic ions and organic substances, and traditional biochemical techniques are difficult to remove these impurities from brine. [0003] Salt elutriation technology is widely used in salt chemical production. However, for zero discharge of high-salt wastewater, it is difficult to use salt elutriation technology to remove a large number of impurity inorganic ions and organic substances in brine, resulting in the fo...
