Seawater desalination treatment system and method

The invention relates to a seawater desalination treatment system and method.The device comprises a waste heat recovery device, the waste heat recovery device absorbs heat of high-temperature gas and generates power steam, and the power steam enters a steam compressor through a first pipeline and drives the steam compressor to generate first-effect heating steam; first-effect heating steam enters a heat exchange pipe arranged in the evaporation system through a second pipeline, the first-effect heating steam releases heat in the heat exchange pipe and heats seawater outside the heat exchange pipe, the seawater enters a spraying pipeline from an original seawater input pipeline through a third pipeline, one end of the spraying pipeline is connected with a sprayer, and the other end of the spraying pipeline is connected with a second pipeline. The sprayer is arranged in the evaporation system, steam generated by seawater outside the heat exchange pipe enters the condenser through a fourth pipeline, and the cond
