Technical Field

[0001] The utility model belongs to the field of stannous chloride production equipment, and particularly relates to a stannous chloride production system for preventing pipeline blockage. Background Technique

[0002] Stannous chloride (SnCl2) is an inorganic compound, which can be used as a bleaching agent, reducing agent, mordant, decolorizing agent and analytical reagent; it is used in industries such as dyes, spices, mirror making, electroplating, etc. and the determination of silver, arsenic, molybdenum, mercury.

[0003] At present, a preparation process of stannous chloride is to add aluminum powder to stannic chloride solution, react to generate aluminum trichloride solution and tin particles. After discharging the aluminum trichloride waste liquid, add stannic chloride solution again, and react with the tin particles to generate stannous chloride solution. Generally, the production equipment shown in Figure 1 is used. When the existing stannous chloride synthesis kettle discharges the aluminum trichloride waste liquid, the tin particles will enter the Y-shaped filter of the kettle bottom pipeline to block the pipeline, which needs to be cleaned frequently, time-consuming and laborious, and the smell will be emitted during cleaning, polluting the on-site environment.
