MICROWAVE FLASH EVAPORATION PROCESS, APPARATUS AND APPLICATION

摘要

A microwave flash evaporation process. The steps of the process comprise: liquid spraying, droplet flash evaporation, microwave enhancement, vacuum exhaustion, and multimode resonant cavity optimization simulation. The problems of the corrosion of circulating pump and steam heat exchange system, and fouling of heat exchanger can be avoided, and the heat transfer efficiency is improved. Also provided is an apparatus for realizing the microwave flash evaporation process, comprising a raw material tank (1), a droplet generation apparatus, a microwave evaporation apparatus and an evaporation water recycling apparatus. The apparatus for realizing the microwave flash evaporation process can be applied in wastewater treatment, seawater desalination, evaporation and concentration of Bayer process pregnant mother solution, concentration and crystallization of chemical product, solution sterilization, solution de-oiling, rectification separation of different kinds of organic mixed solutions, solid powder sterilization, de-oiling and drying.
