[0002] The key to seawater freezing and desalination technology lies in the ice-making desalination method. The commonly used ice-making methods include scraping, direct contact, vacuum, fluidized bed, and supercooled water ice-making, among which the scraping ice-making needs additional power for the scraper. The energy efficiency of the device is uneconomical; the direct contact ice-making refrigerant and seawater contact heat exchange, which requires additional refrigerant phase separation steps, and the process is complicated; the process parameters of the vacuum type and supercooled water type ice-making are strictly controlled, and the system stability is poor; while the fluidized bed The ice making method relies on the continuous collision of small particles in a fluidized state in the ice maker to the heat transfer wall to remove the tiny ice crystals formed on the wall and form a fluid ice slurry.
