[0002] Sodium hydrosulfide is an inorganic compound that is easily soluble in water and alcohol. It is a colorless needle-shaped crystal. In the dye industry, sodium hydrosulfide is used to synthesize organic intermediates and auxiliaries for preparing sulfur dyes; in the leather industry, it is used for dehairing and tanning of raw hides; in the fertilizer industry, it is used to remove monomer sulfur in activated carbon desulfurizers; in the mining industry, it is used in large quantities for copper ore dressing; in the production of artificial fibers, it is used for sulfite dyeing, etc. In addition, sodium hydrosulfide is also a raw material for the manufacture of ammonium sulfide and pesticides, and can also be used in wastewater treatment and other fields.

[0003] At present, when a purification device is used to evaporate and purify sodium hydrosulfide, a sodium hydrosulfide solution is usually injected into a purification barrel, and then the water in the solution is evaporated by high temperature, so that pure sodium hydrosulfide solid can be extracted. However, every time the evaporation is completed, it takes a lot of time to take out the solid in the purification barrel. During this period, the evaporation and purification equipment cannot continue to work, resulting in a long idle time of the equipment, which reduces the utilization rate of the equipment. Therefore, in response to the above problems, we have proposed a new type of sodium hydrosulfide evaporation and purification device. Utility Model Content
