Device and method for removing chloride ions in solid material

Abstract

The invention relates to the technical field of removal of chloride ion impurities in a solid raw material, in particular to a device and a method for removing chloride ions in the solid raw material,and aims to solve the problem that the solid raw material is difficult to effectively utilize because the chloride ion impurities in the solid raw material cannot be more effectively and thoroughly removed in the prior art. The device comprises a container body; a cation selective permeable membrane and an anion selective permeable membrane are arranged in the container body, a sealed cavity formed by the cation selective permeable membrane is a cathode area, and a cathode is arranged in the cathode area; an anode area is formed between the anion selective permeable membrane and the containerbody, an anode is arranged in the anode area, a washing area is formed between the cation selective permeable membrane and the anion selective permeable membrane, and a stirring device is further arranged in the washing area. Chlorine ion impurities in a turbid liquid can be removed through electrolysis of the above device, so that solid raw materials can be utilized more effectively.

Description

technical field [0001] The invention relates to the technical field of removing chloride ion impurities in solid raw materials, and more specifically relates to a device and method for removing chloride ions in solid materials. Background technique [0002] The solid raw materials used in many industries are difficult to be effectively utilized because they contain chloride ion impurities. For example, zinc oxide products obtained by recycling zinc-containing solid waste through fire methods, these solid raw materials must be dechlorinated in advance before entering the production process. use. [0003] In the prior art, the chloride ion impurities in the solid raw materials cannot be removed more effectively and thoroughly, thus making it difficult to effectively utilize the solid raw materials. Therefore, we urgently need a device and method that can remove the chloride ion impurities in the solid raw material more effectively and thoroughly, so that the solid raw materia...
