Description

Technical Field

[0001] The utility model relates to the technical field of ammonium bifluoride preparation, in particular to an impurity removal device for preparing ammonium bifluoride from BOE waste liquid. Background Art

[0002] In the process of preparing ammonium bifluoride using BOE waste liquid, impurity removal is an important step. Specifically, this usually involves using barium hydroxide as a precipitant to remove impurities in the waste liquid. After adding barium hydroxide, it needs to be fully stirred for generally 30-60 minutes, and then filtered to obtain a filtrate. The filter residue is mainly barium sulfate precipitate generated by ammonium sulfate and barium hydroxide in BOE waste liquid, and barium hexafluorosilicate precipitate generated by ammonium fluorosilicate and barium hydroxide. After this step of impurity removal treatment, the impurities in the filtrate are effectively removed, laying the foundation for the subsequent preparation of ammonium bifluoride.

[0003] The impurity removal device for preparing ammonium bifluoride from BOE waste liquid in the past has the following disadvantages: 1. It is not convenient to improve the impurity removal efficiency, and solid precipitation and impurities cannot be gathered on one side of the material stripping plate for quick cleaning. Therefore, those skilled in the art provide an impurity removal device for preparing ammonium bifluoride from BOE waste liquid to solve the problems raised in the above background technology.
