The new method of water desalination of the Chinese Academy of Sciences was patented
A new method of water desalination developed by researchers from Xinjiang Institute of Physics and Chemical Technology, Chinese Academy of Sciences, has recently obtained a national invention patent
.
At present, the common desalination methods mainly include distillation, freezing, ion exchange and membrane methods
.
The new method of water desalination invented by researchers of the Institute of Physics and Chemistry organically combines the distillation method and the membrane method, and uses the high pressure of the concentrated brine side of the membrane method to drive the negative pressure of the venturi jet pump to reduce the subsequent evaporation pressure, so that the evaporation process is carried out under 1 standard atmosphere, which reduces the evaporation temperature, reduces the evaporation energy consumption, and makes the concentration of evaporation residue higher; At the same time, the method can also use the heat of the evaporation residual concentrated liquid for the subsequent crystallization process, and the latent heat of the evaporated steam is used to heat the brine to be evaporated, which further recovers the heat energy and reduces energy consumption
