Description

TECHNICAL FIELD

[0002] With the acceleration of industrialization process and population growth, wastewater discharge increases sharply, which brings serious pollution to natural water bodies. In the production process of raw materials, wastewater containing salt substances is generated. After heating and evaporating the wastewater, the salt-containing harmful substances in the wastewater are distilled, and the water is discharged. The solid waste precipitated is treated as solid waste, and the steam can be recycled as heat source in the factory area. Traditional wastewater treatment methods, such as chemical precipitation and biological treatment, can effectively remove some pollutants, but often have high energy consumption, long treatment cycle, and may cause secondary pollution. Therefore, it is particularly important to develop an evaporation treatment device for salt-containing wastewater.

According to the above, although the device can be well applied, it is not convenient to heat the wastewater by coil type heating, which limits the contact area of heat energy and wastewater, and further affects the evaporation efficiency of wastewater, which often troubles the user.
