Description
technical field [0001] The invention belongs to the field of seawater desalination, relates to a seawater desalination treatment system, in particular to an enhanced heat transfer mechanical compression type seawater desalination system. Background technique [0002] At present, fresh water resources are becoming increasingly scarce, and there is no fresh water in many islands in the South China Sea, which seriously affects people's daily life. China is rich in seawater resources, but due to the very high salinity in seawater, it cannot be used directly and needs to be desalinated for use. Currently, the mainstream methods of seawater desalination include distillation and reverse osmosis. The reverse osmosis membrane method has the advantages of low investment and low energy consumption, but requires high seawater pretreatment. The distillation method has the advantages of mature technology, reliable operation, and large output of the device, but the energy consumption is ...
