Method and device for getting water from dry air

Abstract

The invention relates to a method and a device for getting water from dry air. The method comprises: after air passes through the processing area of a dry runner, moisture in air is held back, and the other puff of air passes through the regeneration area of the dry runner after being heated to take away moisture which is held back; and the moisture is condensed after being cooled. The device comprises the dry runner, a high-temperature refrigerator and a low-temperature refrigerator, wherein after the air passes through the processing area of the dry runner, the moisture in air is held back; the other puff of air is heated after passing through the condenser of the low-temperature refrigerator and the condenser of the high-temperature refrigerator, and the temperature rises; then the air passes through the regeneration area of the dry runner to take away the moisture which is held back; and finally, the moisture is condensed when temperature is lowered after the air through the evaporator of the high-temperature refrigerator and the evaporator of the low-temperature refrigerator. The invention saves cost and lowers energy consumption; two independent refrigeration systems respectively operate to take away the moisture on the dry runner; and then the moisture is fully condensed by passing through the two independent refrigeration systems again. The invention has obvious effect.

Description

technical field [0001] The present invention relates to a method and device for extracting water from dry air. Background technique [0002] China's Xinjiang, Gansu and Ningxia are rich in wind energy resources, but the market demand is small. After the wind power generation installations are put into operation, there are certain problems in electricity sales. In fact, Xinjiang, Gansu, and Ningxia are places where water resources are scarce. The invention of a device that uses electricity to draw water from the air will play a very important role in developing the economy of dry areas such as Xinjiang, Gansu, and Ningxia. [0003] In the southern region, due to the high water content in the air, the dew point of the air is generally above 20°C. As long as the air is cooled, the water in the air can be condensed, thereby obtaining water from the air. [0004] However, in areas with dry air, such as the Gobi Desert in Xinjiang, the lowest relative air humidity in summer is be...

Problems solved by technology

[0004] However, in areas with dry air, such as the Gobi Desert in Xinjiang, the relative humidity of the air in summer is the lowest between 5-15%, and the corresponding dew point temperature is below -4°C. At this time, the energy consumption of moisture in the air can be obtained by cooling the air huge
