Product introduction
Introduction to industrial wastewater evaporator
Industrial wastewater evaporator uses mechanical vapor recompression technology, which is the abbreviation of Mechanical Vapor Recompression (MVR). This technology significantly reduces the demand for external energy and achieves energy saving effects by recycling the secondary steam energy generated by itself.
The working principle of the industrial wastewater evaporator is to use a mechanical compressor or fan to recompress the evaporated secondary steam, thereby increasing its enthalpy value. The secondary steam with increased enthalpy is sent back into the heating chamber as a heat source, and after heating the material, it condenses into water and is discharged. The vaporized and concentrated materials are finally discharged from the system as products.
Industrial wastewater evaporator system composition
The system consists of evaporator, separator, compressor, vacuum pump, circulation pump, operating platform, electrical instrument control cabinet, valves, pipelines and other parts.
Industrial wastewater evaporator system features
The industrial wastewater evaporator only requires a small amount of raw steam to operate, which greatly reduces operating costs and environmental pollution. There is no waste heat steam emission and the energy saving effect is significant.
Due to the use of compressor heating, the temperature difference is smaller than traditional evaporators, which can achieve gentle evaporation, significantly improve product quality, and reduce scaling.
The system structure and process are simple, support fully automatic operation, can run continuously, and are safe and reliable.
The equipment has a built-in CIP cleaning pipeline, which enables on-site cleaning, convenient operation, and no cleaning dead corners.
It is suitable for materials processed by single-effect and multi-effect evaporators. It is technically completely replaceable and has better environmental protection and energy-saving performance.
Industrial wastewater evaporator system application fields
It is widely used in chemical industry, new energy, food processing, coal chemical industry, electric power, electroplating and environmental protection and other industries. It is especially outstanding in links that require efficient and energy-saving evaporation, crystallization and concentration processes, such as solution concentration and extraction of pure solvents in chemical production; material recovery or purification in the battery manufacturing process in the new energy industry; juice, syrup and other liquids in food processing Concentration of food; treatment and recycling of coal chemical wastewater; treatment of desulfurization wastewater in power plants; purification and recycling of wastewater in the electroplating process; and applications in environmental protection fields such as high-salt wastewater treatment and landfill leachate treatment, all of which can significantly reduce costs and increase resources. Recycling rate to help meet strict environmental standards.
Technical principle of
MVR inorganic water evaporator uses mechanical vapor compression (MVR) technology. This technique compressed the evaporator by compressor, expanding its temperature and pressure, and then applied to the evaporator to evaporate again. By this way, the one side can significantly reduce energy consumption during the evaporator, on the other hand can also improve the evaporative efficiency and reach the efficient inorganic water treatment.

Frequently Asked Questions
Q: MVR forced evaporator to run?
Cause: could be the corrosion of secondary steam pipes or steam compressors, pure water quality does not meet the standards, or at the point of equipment such as welding, flange, sealing, expansion, and so on.
Solution: ensure water quality into standards, regularly cleaning the system, maintain stable cooling water temperature, and provide a complete amount of cooling water.
Problem: MVR is required to deflate slow feeding or a small flow situation?
Reason: usually due to the filter is blocked.
Solution: inspection and purification of filters.
