Description

Technical Field

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

[0002] Wastewater treatment mainly uses physical, chemical and biological methods to treat wastewater, thereby purifying wastewater, reducing pollution, and achieving wastewater recovery and full utilization of water resources. In order to effectively treat wastewater during wastewater treatment, corresponding evaporators are usually used.

[0003] However, in the process of wastewater treatment, the existing evaporator contains a lot of impurities. As the water evaporates, the wastewater will gradually become viscous. After long-term use, the impurities are easy to adhere to the inner wall of the evaporator, resulting in a decrease in the working efficiency of the evaporator. It is also easy to cause corrosion to the inner wall of the evaporator. In addition, there is no device in the evaporator to make the wastewater flow. The wastewater is in a static state during the evaporation process, resulting in low evaporation efficiency. Utility Model Content
