MVR is the abbreviation of mechanical vapor recompression technology, which uses the secondary steam and energy generated by the evaporation system itself to compress low-grade steam into a high-grade steam heat source through the mechanical work of the steam compressor. This cycle provides heat energy to the evaporation system, reducing the demand for external energy, thereby improving thermal efficiency, reducing energy consumption, reducing pollution, and achieving the purpose of energy saving. Compared with traditional evaporation technology, MVR evaporation technology has the following advantages:
