Technical Field

When treating industrial wastewater, an evaporation device is usually used to evaporate the wastewater.

[0003] In the existing evaporation device, the wastewater is usually evaporated by an evaporation tank. Since there are many impurities in the wastewater, after the wastewater is evaporated, the impurities remain in the evaporation tank. The long-term residue of impurities in the evaporation tank is likely to affect the evaporation efficiency of the wastewater and reduce the treatment speed of the wastewater.

The long-term residue of impurities in the evaporation tank is likely to affect the evaporation efficiency of the wastewater and reduce the treatment speed of the wastewater. Therefore, we need to propose an impurity filtering device and a wastewater evaporation device. Content of the Utility Model
