The MVR Evaporator is a mechanical vapor recompression (MVR) forced circulation evaporator that is ideal for wastewater treatment. It is designed with a vertical or horizontal structure, depending on the customer's needs. The unique design of the MVR Evaporator allows for customized capacity and customized design pressure, making it a perfect fit for most any application. In addition, the electric driving mode provides high efficiency and reliable performance for any operation. With its superior design and quality construction, the MVR Evaporator is the perfect choice for wastewater treatment.
Working principle
Compress secondary steam by using steam centrifugal compressor or other steam compression device to make sure its physical properties meet with the requirements for heating steam ; evaporation that uses it as heating steam only requires fresh steam supply when the machine is started. After entering normal operation, there is no need to supply new steam and no (or very little) secondary steam needs condensation. Therefore MVR evaporation substantially cuts down steam demand but consumes more power.
Multi-effect evaporation steam consumption
| Effective number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

Steam consumption (t steam/ t water) |
~1.04 | ~0.53 | ~0.36 | ~0.28 | ~0.23 | ~0.19 | ~0.17 | ~0.15 |
Main characteristics
1)Main driven power of MVR evaporation system is electric energy. Electric energy transfer to mechanical energy and improve the quality of second steam which is more economic than produce or purchase fresh steam.
2)Under most of the evaporation process, system no need fresh steam during operation. Only need some steam compensation for pre-heating the raw material when heat energy from product discharged or mother liquid cannot be recycled due to process requirement.
3)No need independent condenser for second steam condensation, so no need circulating cooling water. Water resource and electric energy will be saved.
4)Compared with traditional evaporators, MVR evaporator temperature difference is much smaller, can achieve moderate evaporation, greatly improve product quality and reduce fouling.
5)Evaporation temperature of system can be controlled and very suitable for evaporation an concentration of thermal sensitive product.
6)Lowest energy consumption and operation cost,electricity consumption of one ton water's evaporation is 2.2ks/C.
Application
Applied to multiple areas, such as: "zero release" solution for industrial waste water, Evaporation and concentration for process industry, food fermentation (aginomoto, citric acid, starch and sugar), pharmacy (traditional Chinesemedicine preparation, low temperature concentration of western medicine), fine chemical (pesticide, synthetic dyes, organic pigments, paints, spice and essence, cosmetic), chlorine chemical (salt water concentration), seawater desalt and metallurgical industry, etc.
