What are the differences between high-salt wastewater evaporators and chemical wastewater evaporators? What is the difference in their functions? How to choose!

The principle is similar, but the uses are different; it mainly depends on where it is used

Different water qualities result in different salt contents as well as different increases in boiling point

In high-salt evaporation, evaporation is carried out until crystallization occurs to obtain salt; in the case of chemical wastewater, concentration followed by treatment or emission reduction is typically used. The applications are different, but the processes are not very distinct, while the materials used vary greatly. This is a quite general issue without any specific focus

The secondary steam that comes out of the evaporator is compressed by a compressor, resulting in an increase in pressure and temperature as well as an increase in heat content. This steam is then sent to the heating chamber of the evaporator where it is used as heating steam to keep the liquid material in a boiling state, while the heating steam itself condenses into water. In this way, the steam that would otherwise have been wasted is made full use of; the latent heat is recovered, and thermal efficiency is improved. The economic efficiency of the generated steam is equivalent to that of 30-effect multi-effect evaporation. Commonly known as an MVR evaporator, it is also referred to as a heat-pump MVR. 　　Evaporation equipment is compact, occupies little space, and requires minimal area. The cooling system can also be omitted. For existing factories that need to expand their evaporation equipment and face insufficient steam and water supply capabilities as well as limited space, especially in cases where low-temperature evaporation requires chilled water for condensation, this approach can result in cost savings along with improved energy efficiency. By utilizing the latent heat of vaporization of secondary steam, only 30 kW of energy is required to evaporate one ton of water. Due to low-temperature evaporation, evaporation can occur at 30 degrees; with low-temperature evaporation, the COD level can be reduced by an order of magnitude. Of course, the comprehensive treatment of saline wastewater requires integrated approaches. In terms of evaporation energy consumption, using 30 kW to evaporate one ton of water is a relatively inexpensive option. http://www.zjtaikang.com/imageRepository/c6badde0-90e4-451c-8161-5166072b7208.jpg MVR high-salinity wastewater evaporator
