Description

TECHNICAL FIELD

[0001] The utility model belongs to air water technology field, especially relate to a system of taking pure water from natural air. BACKGROUND

[0002] With the development of industry and the prosperity of commerce, the drinking water sources of most cities in the world and in China are damaged to varying degrees, and the tap water system can only guarantee basic supply, and it is difficult to guarantee drinking water safety through a single source. Due to water pollution, including heavy metal pollution, organic matter pollution, pesticide pollution, chemical fertilizer pollution, agricultural breeding pollution, urban liquid waste discharge, etc., the water body deteriorates, the self-purification capacity of the water body is lost, and drinking water safety is difficult to guarantee.

[0003] Drinking water safety is one of the most important guarantees for human health, and is equally important as air quality safety. Distributed water supply is one of the effective means to solve the drinking water safety of residents. Developing air water resources is the main direction of distributed water production. Air water has been proposed for a long time to ensure the drinking water safety of residents in water shortage areas and water pollution areas.

[0004] There are five common ways of air water production, including compressor refrigeration condensation water production, compressed air supersaturation water production, adsorption water production, radiation refrigeration condensation water production, and adsorption refrigeration condensation water production. Under high temperature and high humidity conditions, compressor refrigeration has a comparative advantage, and the water production is fast and efficient. When the relative humidity is lower than 65%, the efficiency of compressor refrigeration is lower than that of adsorption water production. At the same time, the power consumption of compressor refrigeration is relatively large, one degree of electricity can produce 2 liters of water, and 20 liters of water need 10 degrees of electricity, which is relatively high for household electricity consumption.

[0005] Adsorption refrigeration uses lithium chloride, calcium chloride, magnesium chloride, silica gel, zeolite molecular sieve, activated carbon, etc. as water adsorbent to adsorb water in the air, and uses electric heating to dehydrate and condense water. The energy consumption mainly includes heating energy consumption and cooling energy consumption. At the same time, the chlorides have strong corrosion, which leads to a short service life. The silica gel, zeolite, and activated carbon adsorption water production will increase the health risks in air water production due to the adsorption of indoor harmful gases such as formaldehyde, benzene, hydrogen sulfide, ammonia, and radon, and cannot guarantee the safety of drinking water.

[0006] The radiation refrigeration refrigeration power is 100 watts per square meter, which meets the needs of 15-20 square meters of water production for a family, and the cost is relatively high, and the use is not convenient. At present, it is not mature. Compressed air water production is to increase the temperature of compressed air by air compressor, so that the water content exceeds the saturation water content, and the water is condensed. Due to the high energy consumption of air compressor and the loud noise, it is difficult to realize the large-area application of household water production. UTILITY MODEL CONTENT
