Composition:
Low-noise thermal compressor, first-effect heater and evaporator, second-effect heater and evaporator, condensator, storage tank, pipelines.
operation principle:
The first-effect steam is not only used as the second-effect heat source, but also decompressed part of the steam to used for the first-effect heat source by the way of low noise hot pressing pump. That will greatly reduce steam and water consumption during the course of the concentration and it can save energy and water.
