Mechanical vapour recompression, namely Mechanical Vapor Recompression (MVR) technology. It significantly reduces the need for external energy by recovering and reusing the secondary steam energy generated during the evaporation process.

In mechanical vapour recompression, a mechanical compressor or fan is used to recompress the secondary steam after the evaporation process, thereby increasing its enthalpy value. The enthalpy-increased steam is returned to the heating chamber as a heat source to heat the feed and is eventually converted into condensed water for discharge. After the material is heated, evaporated and concentrated, it is discharged from the system as the final product.

The vapor recompression mechanical system consists of evaporator, separator, compressor, vacuum pump, circulation pump, operating platform, electrical instrument control cabinet, valves, pipelines and other main parts, forming a complete set of high-efficiency and energy-saving solutions.

Significant energy saving effect: The steam recompression machinery only needs a small amount of raw steam to operate, significantly reducing operating costs and environmental pollution, and there is no waste heat steam emission.
Improve product quality: Using a compressor for heat supply, compared with traditional evaporators, the temperature difference is smaller and can achieve gentle evaporation, which helps to improve product quality and reduce scaling.
Simple operation and maintenance: The system design is simple, supports fully automatic operation, and can run continuously to ensure safety and reliability.
Easy to clean: The equipment has a built-in CIP cleaning pipeline, which facilitates on-site cleaning. It is easy to operate and has no cleaning dead corners.
Wide range of material adaptability: It is suitable for materials processed by single-effect and multi-effect evaporators. It can completely replace traditional technology and has better environmental protection and energy-saving performance.

Chemical industry: Used for solution concentration and extraction of pure solvents, effectively reducing energy consumption.
New energy industry: Such as material recycling or purification processes in battery manufacturing.
Food industry: Concentrate juice, syrup and other liquids to increase concentration and retain flavor.
Coal chemical industry: Effective treatment and recycling of wastewater containing chemical substances.
Electric power industry: Such as power plant desulfurization wastewater treatment, reducing costs and improving water resource recycling rate.
Electroplating industry: Purify and recycle wastewater containing heavy metals and other harmful substances.
Environmental protection field: Address environmental issues such as high-salt wastewater treatment and landfill leachate treatment, reduce pollutant emissions, and meet environmental protection standards.

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.
