water ratio of system, drop Low concentrated water amount, concentrated water counter-infiltration system are reverse osmosis using network pipe type；(7), counter-infiltration system concentrated water enters MVR evaporators after water tank caches, and MVR evaporators utilize two produced in evaporator Secondary steam, compresses through compressor, pressure, temperature rise, heat content increase, is then delivered to the heating chamber of evaporator as heating steam Use, feed liquid is maintained fluidized state, and heat steam and be then condensed into water in itself, liquid reuse, concentrate committee are evaporated after evaporation Outside.
