Product introduction
The mvr system, the mechanical vapor recompression system (Mechanical Vapor Recompression), represents an advanced energy-saving technology. This system significantly reduces the need for external energy by recovering and reusing the secondary steam energy generated during the evaporation process.
In the MVR system, a mechanical compressor or fan is used to recompress the secondary steam after the evaporation process, thereby increasing its enthalpy value. Subsequently, the steam with increased enthalpy is returned to the heating chamber as a heat source to heat the material and is eventually converted into condensed water for discharge. The vaporized and concentrated material is discharged from the system as the final product.
MVR system composition
The mvr system consists of evaporators, separators, compressors, vacuum pumps, circulation pumps, operating platforms, electrical instrument control cabinets, valves, pipelines and other major parts, forming a complete set of high-efficiency and energy-saving solutions.
MVR system features
Significant energy saving effect: The mvr system only requires 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.
MVR system application fields
The mvr system is widely used in many industrial fields such as chemical industry, new energy, food processing, coal chemical industry, electric power, electroplating and environmental protection. It is especially suitable for evaporation, crystallization and concentration processes that require high efficiency and energy saving.
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.
Q: The steam reduction charged by MVR?
Cause: could be due to system clogging or dirt in the hot water catheter.
Solution: do online purification programs for cleaning dirt.
Q: The effect of steam valve charged by MVR?
Cause: The material is processed after thickening, crystally, resulting in clogging.
Solution: The Prevention includes regular filter of salt and spray as well, once stuck, use juice or vacuum treatment.
Q: MVR compulsory evaporator effect?
Expression: Produces regular and loud sound, vibrates the pipes.
Solution: constant current stability compressor when counter rate is soft and open the valve through the appropriate rate; counter rate need to close the compressor immediately for testing, pay attention to liquid temperature to avoid counter rate.
Q: cool MVR evaporator don't work properly?
Cause: could be due to too thick dust, or vacuum drop.
