A mechanical vapor recompression (thereinafter abbreviated MVR) evaporator is a evaporation and concentration equipment, recycling the secondary steam completely with compression.
Application Scope
The MVR evaporator is suitable for concentration and crystallization of various material, especially for material of small boiling point elevation and diluted material which are easy to be evaporated.
Main Principle
The MVR (mechanical vapor recompressor) is able to take use of the secondary steam produced in the evaporator. After compressed by the recompressor, both pressure and temperature of the secondary steam are increased, and the caloric capacity increased as well, then it is sent to heating chamber of the evaporator as heat source for heating up material inside. In this way, the waste steam is fully reused, the heat efficiency is increased, the demand for external heat supply and cooling water decreases, and the engery consumption is reduced.
System Configuration
A MVR evaporator is composed of heaters, separator (crystallizer), MVR, vacuum pump, material circulating pumps, operation platform, instrumentation and control cabinet, and pipline and fittings.
MAIN FEATURE
1.MVR Evaporator is the international advanced evaporator, a tiny amount of live steam is required (the tiny amount of steam is required for startup, and then almost none is needed for normal operation), reduces the operation consumption and the enviromental pollution.
2.Compared to the traditional evaporator, the temperature difference is smaller because the heat source is provided by the compressor, thus the evaporation is gentler, which improves the product quality greatly and reduces the scale.
3.No need of condenser or a small condenser is workable, the structure and the process flow are simple, easy to realize full automation, safe and reliable.
4.There is built-in CIP cleaning pipeline, is able to realize on-site cleaning, which is easy to operate, and free of blind spot.
5.The material is evaporated under condition of low temperature (evaporation temperature @ 50℃～100℃) and free of foam. The material is uniform and not easy to coking or denaturation.
6.The installation space of MVR evaporator is about two times that of the traditional multi-effect eavporator, the investment cost is higher too, and operation cost is much lower.
7.In order to avoid failure of MVR caused by misoperation, automatic operation system is necessary for protecting safe operation of equipment.
TREATMENT CAPACITY
