Key equipment for industrial wastewater evaporator

In modern industrial production processes, the generation of wastewater is inevitable. In order to protect the environment and achieve sustainable development, Wastewater treatment technology has become particularly important. Among them, the wastewater evaporator, as an efficient Wastewater treatment equipment, has been widely used in many industries.

The working principle of wastewater evaporator is based on the evaporation process of liquid, which evaporates the water in the wastewater through heating, thereby achieving the purpose of concentrating or separating pollutants. This process not only effectively reduces the volume of wastewater, but also recovers valuable substances such as salt or other reusable components. According to different operating methods, wastewater evaporators can be divided into various types such as single effect, multi effect, and mechanical vapor recompression (MVR).

A single effect evaporator is the most basic form, which uses only one evaporator chamber to complete the entire evaporation process. Although the structure is simple and the cost is low, its energy efficiency is relatively low. In contrast, the multi effect evaporator improves energy utilization by connecting multiple evaporation chambers in series, allowing a portion of the secondary steam generated by evaporation to be used as the heat source for the next evaporation chamber, greatly saving energy consumption. And MVR technology has taken this energy-saving concept to the extreme - by using mechanical devices to increase the pressure and temperature of low-temperature and low-pressure steam, making it a new heat source to continue participating in the evaporation process, almost achieving zero emissions.
