Product introduction
5t/h MVR evaporator composition
The 5t/h MVR evaporator system consists of the following main components: evaporator, separator, compressor, vacuum pump, circulating pump, operating platform, electrical instrument control cabinet and various necessary valves and pipelines. These components work together to ensure an efficient and stable evaporation process.
5t/h MVR evaporator features
1. High efficiency and energy saving: The system uses mechanical steam recompression technology to significantly reduce energy consumption and improve heat utilization efficiency. Energy consumption is significantly reduced by recycling secondary steam.
2. Compact design: The evaporator covers a small area, compact design, easy installation and maintenance, especially suitable for limited space places.
3. Environmental performance: Reduce the burden on the environment by realizing zero waste water discharge and resource utilization, and meet the current strict environmental protection standards.
4. Automated operation: equipped with advanced intelligent control system, simplifying the operation process, reducing labor costs, and improving the accuracy and reliability of the operation.
5t/h MVR evaporator applications
5t/h MVR evaporators are widely used in many industrial fields due to their efficient performance, especially in industries that require energy-efficient evaporation, crystallization and concentration processes:
1. Chemical industry: concentration of solution or extraction of pure solvent in the chemical production process, MVR evaporator can effectively complete these processes, while greatly reducing energy consumption.
2. Environmental protection: To deal with environmental management problems such as high-salt wastewater and landfill leachate, MVR evaporator provides an effective solution to help reduce pollutant emissions and meet relevant environmental standards.
3. New energy industry: The use of evaporation technology to recover or purify substances in production processes such as battery manufacturing.
4. Food industry: It is used to concentrate juice, syrup and other liquid foods in food processing to improve product concentration while retaining its original flavor.
5. Coal chemical industry: effective treatment and recycling of wastewater containing a variety of chemical substances produced by coal chemical industry.
6. Power industry: It is applied in the treatment of desulfurization wastewater in power plants to reduce treatment costs and improve the recycling rate of water resources.
7. Electroplating industry: used for purification and recovery of wastewater containing heavy metals and other harmful substances produced in electroplating process.
Technical principle of
MVR evaporator technical principle for heavy metal sewage:
In the working process of MVR evaporator for heavy metal waste water, the first time sewage is heated to the boiling point by pre-heater. Then it is taken to the body of the evaporator and boiled in it to produce steam, while the heavy metal ions in the sewage water are concentrate. The results steam gets into liquid aerator, separation of pure vapor and concentrated liquid. Pure steam to the return of the evaporator as the heat source after strengthening by the vapor compressor, while the concentrate is further processed or recalled by the exhaust system.

Frequently Asked Questions
Q: MVR forced evaporator to run?
Cause: could be the corrosion of secondary steam pipes or air 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.
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.
Q: MVR is required to circulation irregular level of steam separator?
Cause of the high level: too many data feed, Crystal pump fault or export focus clogging.
Solution: reduce the amount of data input, check the pump, open the drainage pipe.
Cause of the low level: too small or leaking of the concentration tube.
Solution: increase the amount of data input, check the drainage pipe.
