Patent. No.: 94216744
Title of Invention: Solar seawater desalination and heating combined device
Abstract: A solar seawater desalination and heating combined device is composed of a solar water heater and water vapor separation The seawater first enters the cold water jacket in the heat exchanger and flows upward, and then flows from top to bottom, and is output by the water heater and separated by gravity in the water vapor separator and flows into the condensation tube. The water vapor exchanges heat with the 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. After the water vapor is condensed, it becomes pure water and is discharged. The hot water can be led out from the middle of the heat exchanger for use or discharged. Device. This device is suitable for use as a life support facility in isolated islands, desert areas and motorized fishing boats.
