Product introduction

 

Introduction to Mechanical Vapor Recompression (MVR) Technology

 

Mechanical vapor recompression technology, referred to as MVR. It is an efficient energy-saving technology. This technology significantly reduces the need for external energy by recovering and reusing the energy of the secondary steam produced during the evaporation process.

In a mechanical vapor recompression (MVR) system, a mechanical compressor or fan is used to recompress the evaporated secondary vapor to increase its enthalpy value. Subsequently, the steam with increased enthalpy 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.

 

 

Mechanical vapor recompression (MVR) system components

 

The system consists of main parts such as evaporator, separator, compressor, vacuum pump, circulation pump, operating platform, electrical instrument control cabinet, valves and pipelines.

 

 

Mechanical Vapor Recompression (MVR) System Features

 

Significant energy saving effect: The mechanical vapor recompression (MVR) system only requires a small amount of raw steam, significantly reducing operating costs and environmental pollution, and there is no waste heat steam emission.

Improved product quality: Using a compressor for heat provides a gentle evaporation process compared to traditional evaporators, which helps 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.

 

 

Mechanical Vapor Recompression (MVR) System Application Areas

 

This technology 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.

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.

 

 

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.
Solution: add agent foaming agent, check detector and dehumidifying liquid, import steam valve adjustment, vacuum control.
