The multi-effect wastewater evaporator is based on the principle of evaporation, concentration and crystallization for the characteristics of chemical organic wastewater with high salinity and concentration. The multi-effect reduced pressure evaporation is used to concentrate and crystallize the organic wastewater. After the salt in the concentrated solution is separated, it is recovered by the salt collector. , The concentrated liquid is dried and recycled or incinerated, and the evaporated condensate is generally treated by subsequent biochemical treatment, which can achieve wastewater discharge standards.
Wastewater evaporation and crystallization equipment is expensive mechanical equipment. If the production demand cannot be used after purchase, or the enterprise changes the production mode. The existing wastewater evaporation and crystallization equipment is not suitable for the new mode needs, and the existing wastewater evaporation and crystallization equipment is discarded. reality. In this case, the wastewater evaporation and crystallization equipment can be modified, and the specific modifications are as follows:
1. Improve the automation degree of wastewater evaporator, realize numerical control and linkage;
2. Realize automatic control;
3. Make the parts universal, serialized and standardized.
4. Convert the wastewater evaporator into a high-efficiency, dedicated wastewater evaporator;
5. Improve the reliability and maintainability of the components of the wastewater evaporator;
6. Modified wastewater evaporator monitoring and monitoring device;
7. Improve the lubrication and cooling system;
8. Improve the process performance of wastewater evaporator;
9. Improve safety, protection devices and environmental pollution systems;
10. Reduce raw material and energy consumption of wastewater evaporator.
