Energy-Saving Pillow plate sheet exchanger for MVR evaporation system

MVR evaporators minimize energy consumption
MVR evaporators (sometimes referred to as a Vapor Compression Evaporator) removes water from mill liquors or effluents with minimum energy consumption and maximum plant availability while delivering high condensate quality.

The evaporators have lamella heating surfaces. Inherently non-foaming, these evaporators are ideally suited for the low dry solids applications of MVR evaporation with capacities from 10 to 200 t/h in a single unit.

MVR evaporators operate on a “heat pump” principle. The evaporated water vapor is recompressed with a simple, low-speed centrifugal fan or compressor which increases the saturation temperature of the vapor. After the fan, vapor can be used as heating steam in the same unit. The recompressed vapor condenses and releases its latent heat through the heat transfer surface for further evaporation of the liquor or effluent.

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 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.
