Product introduction
Efficient treatment of different types of solutions
- MVR evaporators
MVR evaporators are used in the manufacturing industry and various industries. The introduction of evaporation equipment into production helps to save resources and reduce costs: clean distilled water is returned to production, and less money is needed for waste treatment. MVR evaporators can be used for liquid treatment in plants producing inorganic salts, nitrogen fertilizers, paint and varnish industry, electroplating production, pharmaceuticals, and confectionery factories. The technology can significantly reduce the amount of waste treatment.
What can MVR evaporators bring?
- Provides evaporation of solutions with a wide range of capacities.
- There is no waste heat steam discharge, and the energy-saving effect is very significant.
- Reduced energy costs compared to single-shell units.
- Only a very small amount of raw steam is required.
- Fully automatic operation, continuous operation.
MVR evaporator system profile
MVR steam compressor engineering is a Steam digital compressor (intrusion engineering) mute. An evaporator is an energy-saving technology that reuses energy from the secondary steam itself to reduce the need for external energy.
MVR is evaporated by the steam compressor (or fans) the secondary steam after the evaporator and compressed to increase the value of atrophy, enthalpy increases after the secondary steam is sent into the heating room as a source of food heat again, The Heat stage converts to condenser water. The heating material is enriched by steam and then it releases the system.

Technical principle of
MVR steam mechanical recompression technology is the abbreviation of mechanical vapor recompression technology. MVR evaporator is an energy-saving technology that reuses the energy of the secondary steam it produces, thereby reducing the demand for external energy.
MVR evaporator uses a mechanical compressor (or fan) to recompress the evaporated secondary steam to increase its enthalpy value. The secondary steam with increased enthalpy value is sent to the heating chamber again as a heat source to heat the feed, and its exothermic phase changes into condensed water and is discharged. The heated material is discharged from the system as the final product after vaporization and concentration.
The production process of
MVR system evaporation process:
A. Feeding process:
The wastewater raw liquid is sent to the preheating system through the feed pump to exchange heat with distilled water for heating, and the heated wastewater raw liquid enters the separator.
B. Evaporation process:
After entering the separator, the wastewater raw liquid is sent to the heater through the circulating pump, and heat is exchanged with the high-temperature secondary steam. The secondary steam condenses into water and enters the distilled water tank. The circulating liquid absorbs the heat of the steam, flashes in the separator, and separates the gas and liquid. The concentrated liquid is returned to the evaporator by the circulating pump to continue evaporation until the predetermined concentration is reached.
C. Discharging process:
When the predetermined evaporation concentration is reached, the system controls the discharging.
Non-condensable gases are automatically discharged through system control.
D. Drainage process:
The distilled water temporarily stored in the distilled water tank is transported to the preheating system through the distilled water pump, exchanges heat with the wastewater raw liquid for cooling and then is sent out of the system.

Frequently Asked Questions
Q: Does MVR force the 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 to standards, regularly clean 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 being blocked.
Solution: inspection and purification of filters.
Q: The steam reduction charged by MVR?
Cause: this 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 the steam valve charged by MVR?
Cause: The material is processed after thickening, usually, resulting in clogging.
Solution: The Prevention includes a regular filter of salt and spray as well, once stuck, use juice or vacuum treatment.
Q: MVR compulsory evaporator effect?
