It includes heater,separator, compressor, vacuum pump, circulation pump, operation platform, electric control cabinet, liquid level automatic control system & internal valve&pipe fittings, the structure is quite simple.
Its principle is to use high energy efficient steam compressor to compress evaporation of secondary steam, converts electrical energy into heat energy , and improve the secondary steam enthalpy, the improving heat secondary heating steam be feeding into the evaporation chamber for heating, in order to achieve cyclic utilization the existing secondary steam heat, so no need feed external live steam, rely on the evaporator since the cycle to achieve the purpose of evaporation concentration.Theoretically using MVR evaporators save more than 80% of energy than conventional evaporator, save more than 90% water, reduce more than 50% of floor space.
Main principle: Mechanical vapor recompression MVR evaporator using secondary steam generated in the evaporator, after compressing, the pressure/temperature/ enthalpy increased, and then feed to the heating chamber as heating source, which make the liquid keep boiling, while the heating steam will be cooled into condensate water. In this way, have made full use of the secondary vapor and recover latent heat& improve heat efficiency, live steam economy is equivalent to 30 effect of multi-effect evaporation, reduced the demand of external heating and cooling resources, reduce the energy consumption and reduce pollution.
1.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.
2. 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.
3.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.
4.This evaporator internal system equipped with CIP clean pipeline, which can achieve clean in place, easy to operate and without dead angle.
5. 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.
6. Due to use of 100% recycling secondary steam latent heat, completely avoid the use of live steam, so greatly reduced steam consumption.
7. 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 ℃.
8. 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.
9. The handling capacity can be up to 100T/h, with advantages such as small floor space, compact structure, stable operation and so on.
