Patent number: 942 16744
Name of invention: solar seawater desalination and heating combined device
Abstract: The solar seawater desalination and heating combined device consists of a solar water heater, a steam separator and a three-stream heat exchanger. Seawater first enters the cold water jacket in the heat exchanger and flows upstream, and exchanges heat with the steam flowing from top to bottom, output by the water heater and separated by gravity in the water vapor separator, and hot water flowing into the hot water pipe, and then flows into the solar water heater to be heated until the water vapor mixture is output. Water vapor is condensed and discharged as pure water, and hot water can be taken out of the heat exchanger or discharged from the device. The device is suitable for isolated islands, desert areas and motorized fishing boats as life support facilities.
