Product Description

Low Steam Consumption Double Embossed Pillow Plate Evaporator


MVR Applications 

MVR energy-saving, low-temperature evaporation technology replaces simple evaporators. MVR is widely used in many applications, including:

Zero Liquid Discharge for industrial wastewater treatment

Chemical industry for evaporation, crystallization, and purification

Salt brine concentration

RO brine concentration

Beverage industry (milk, juice, sugar, etc.) concentration

Food industry (MSG, soy, protein, sugar) concentration

Pharmaceutical industry (medicines, vitamins) concentration


Product introduction

The MVR evaporator compresses the low-temperature steam through the compressor, increases the temperature and pressure, and increases the enthalpy, and then enters the heat exchanger for condensation to make full use of the latent heat of the steam. Except for the start-up, the secondary steam from the evaporator without raw steam during the entire evaporation process is compressed by the compressor, the pressure and temperature increase, and the enthalpy increases, and then it is sent to the heating chamber of the evaporator to be used as heating steam. Keep the material liquid in a boiling state, while the heating steam itself condenses into water. In this way, the previously discarded steam is fully utilized, latent heat is recovered, and thermal efficiency is improved.


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.


Main characteristics

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.

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.

No need independent condenser for second steam condensation, so no need circulating cooling water. Water resource and electric energy will be saved.

Compared with traditional evaporators, MVR evaporator temperature difference is much smaller, can achieve moderate evaporation, greatly improve product quality and reduce fouling.

Evaporation temperature of system can be controlled and very suitable for evaporation an concentration of thermal sensitive product.

Lowest energy consumption and operation cost.

Note:In operation cost estimation:steam 150rmb/t,electricity 0.6 rmb/kWh,water 0.5rmb/t.


The investment of combined evaporation process equipment increased: evaporator (2500 m2) 375x10000 RMB; MVR compressor 400x10000rmb, total 775x10000 RMB


Annual operating cost reduction of combined evaporation process: 3672-2115 = 1557 (10000RMB)


Investment increase payback period of combined evaporation process: 755 ÷ 1557=0.5year


It can be seen that taking the scale of 100t / h as an example, the combined evaporation process can recover the increased investment in half a year, and save 1557 (10000 RMB) every year in the future, with considerable economic benefits.
