Technology Study Of Seawater Desalination With Thermal Vapor Compression(TVC)

The research of the evaporation technique of the seawater desalination with thermal vapor compression (TVC) was focused on in the paper. The design model of seawater desalination with the TVC falling-film evaporation process was deduced. The transfer coefficient of falling-film evaporation process was analyzed in detail. And the effect of the parameter change of process steam to the operation of the device was calculated and discussed.Multi-function experiment device of the seawater desalination with the TVC spraying falling-film evaporation process was designed by means of AutoCAD. Now, the device has been manufactured. Many testing can be studied by this device, such as spraying falling-film,falling-film evaporation and performance of steam ejector.It was taken into account that the experiment device can also be rebuilt as little scale device with the mechanical vapor compression (MVC) evaporation, And the frame require of the MVC device was given attention to in the design of the experiment device. In an appropriate time, this experiment device will be equipped with centrifugal compressor and be rebuilt as the MVC product that is the advanced technology of seawater desalination in the world.
