Description

Technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a distillation seawater desalination system and a desalination method. Background technique [0002] At present, the seawater desalination process by distillation mainly includes vapor compression distillation, multi-stage flash distillation, and low-temperature multi-effect distillation. Steam compression seawater desalination is to send the preheated seawater into the evaporator and partially evaporate in the evaporator. The generated steam is compressed by the compressor to increase the pressure and then introduced to the heating side of the evaporator, and the steam is condensed and led out as product water . Multi-stage flash seawater desalination is to evaporate heated seawater in multiple flash chambers with gradually decreasing pressure, and condense the steam to obtain fresh water. Multi-effect evaporative seawater desalination is to evaporate the heated sea...
