Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an evaporator for wastewater treatment. Background Art

[0002] Many production fields will produce wastewater containing a large amount of inorganic salts, such as sodium chloride, sodium sulfate, sodium carbonate, etc. These inorganic salts have always been one of the difficulties in wastewater treatment. If the inorganic salts in the wastewater are recovered, these inorganic salts can be used as raw materials in the production process, saving costs and avoiding waste of resources, and can also avoid environmental pollution and realize the recycling of resources. The evaporator for wastewater treatment evaporates the wastewater at low temperature, concentrates the solids in the wastewater, and separates the liquids for reuse.

[0003] When the existing evaporator for wastewater treatment is in use, as the water evaporates, the wastewater will gradually become viscous, leaving impurities in the evaporation tank body. After long-term use, various impurities are likely to adhere to the bottom of the inner wall of the evaporation tank body, which not only easily causes corrosion to the inside of the evaporation tank body, but also leads to reduced heating efficiency. Therefore, an evaporator for wastewater treatment is proposed. Utility Model Content
