Abstract
The invention provides a method for utilizing clean energy to extract freshwater from air. The method comprises the steps of utilizing a drive plunger pump to input seawater with a depth larger than 50 meters to a condensing device, filling air with humidity larger than 50% in the surface of the condensing device, and obtaining the freshwater on the surface of the condensing device. The invention further provides a freshwater extracting device which comprises the drive plunger pump, a humid air input device, the condensing device and a freshwater collecting device. The water outlet of the drive plunger pump is connected with the water inlet of the condensing device. The air output mouth of the humid air input device is communicated with the surface of the condensing device. The freshwater collecting device is in contact connection with the surface of the condensing device. According to the method for utilizing the clean energy to extract the freshwater from the air and the freshwater extracting device, a water pump is used for continuously leading the low-temperature seawater into the condensing device, cold energy enables water vapor in the air to be condensed and separated out, and therefore the freshwater is extracted. Therefore, the drive plunger pump which dose not consume electricity, coal, oil, liquefied gas and other conventional energy resources is adopted, the cold energy is fully utilized, energy resources are saved, and simplicity and practicality are achieved.
Description
technical field [0001] The invention relates to the field of fresh water extraction, in particular to a method and a fresh water extraction device for extracting fresh water from air by using clean energy. Background technique [0002] The atmosphere contains about 13 trillion m 3 The amount of water in China is more than six times that of all rivers and rivers around the world, about 2% of which has become water droplets in clouds, and the remaining 98% is still in the state of water vapor. Especially the air in coastal areas, islands, seas and coasts is very humid, with high moisture content and low salt content. [0003] Humid air is a mixture of dry air and water vapor. When the humid air is cooled, if the humid air is in an unsaturated state, its moisture content will not change, the temperature will drop, and the cooling process of unsaturated humid air will extend to a certain moisture content As the temperature decreases, the relative humidity increases. If the hu...
