High efficient multiple effect vacuum evaporator for seawater/industrial water chinese supplier


MVR Description

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. The economy of raw steam is equivalent to 30 effects of multi-effect evaporation.


Main features:

The MVR evaporator energy saving technology is the most advanced international technology of evaporator, only need few live steam (When start evaporator need few live steam, during normal running almost no need live steam), which greatly reduce business operating costs, reduce environmental pollution.

Due to adopt compressor supply heat source, there is little temperature difference which compared with traditional evaporator, and can achieve moderate evaporation,greatly improved product quality and reduce fouling.

No need condenser or only need small size condenser, the structure and process are quite simple, it can be full automatic operation, continuous running, safety and reliable.

This evaporator internal system equipped with CIP clean pipeline, which can achieve clean in place, easy to operate and without dead angle.

Liquid material can be evaporated under low temperature (50-100℃) in this evaporator, the liquid material is uniform and without running material, not easy coking, material heating denaturation is minimal.

Due to use of 100% recycling secondary steam latent heat, completely avoid the use of live steam, so greatly reduced steam consumption.

For heat-sensitive materials can be used with vacuum pump, which can be done in close to absolute pressure under vacuum, so as to realize low temperature evaporation, the minimum evaporation temperature can be 50 ℃.

Simple process control and automation——Because of the small amount of fluid retention, the falling film evaporator can be change according to different vacuum degree/feeding capacity/ concentration/ temperature , which is the basic conditions for stable quality of products.


In summary the adventages of MVR system are as follow
1.Energy saving: high thermal efficiency, energy saving, lower power consumption,the energy consumption is about 1/6To 1/5 of traditional evaporator. significantly reduc the operation cost
2.Environmental protection
3.Low operating costs: only the traditional evaporators One-third to half
4.Evaporating temperature is low, difficult to corrosion stainless steel equipment, difficult to scale, very suitalbe for heat-sensitive material
5.Automatic: The entire system realized automatic control from the filling, preheating, evaporation, cleaning, maintenance and other steps of the. Avoid human error, reduce the labor costs, improved product quality
6.Small footprint
7.Avoiding the purchase of boilers, chimney construction investment and maintenance costs



Operation cost comparison

The operation of the two evaporation processes for the treatment is shown in the table.

Operation of two evaporation processes for treating paper waste water.

RMBx10000/Day 10.8 6.2
RMBx10000/Year(340days) 3672 2115

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.

The handling capacity can be up to 100T/h, with advantages such as small floor space, compact structure, stable operation and so on.
