The hydrophilic packing 312 resembles the trays in a fractionation column according to the tray theory of the column, and the height and nature of the packing determines the number of theoretical trays and the tray height. In each tower plate, according to the similar compatibility principle, nonpolar molecules such as nitrogen, carbon dioxide and oxygen with larger content in the air have small acting force with the hydrophilic packing 312, are separated from the tower plate firstly, and polar water molecules with large acting force are separated later (the outer side of the hydrophilic packing 312 is polar). After multiple separation through multiple trays, nonpolar molecules such as nitrogen, carbon dioxide, oxygen and the like with high content in the air are separated from the hydrophilic filler 312 and escape from the top end of the device, while water molecules are enriched outside the hydrophilic filler 312 to form water drops which fall into the cylindrical water collecting tank 42.

The air speed of an air inlet of the air water collecting device is 0.4-0.8 m/s, the average air speed is 0.56m/s, the air speed of an air outlet is 0.5-0.9 m/s, the average air speed is 0.64m/s, and due to the influence of factors such as environment, the air speeds of the air inlet and the air outlet of the air water collecting device are slightly different, but the difference is not large. The wind speed of the wind outlet is large and is mainly influenced by the wind wheel of the power mechanism. The air flow of the air collection unit can be calculated here as the average air speed of the air inlet opening of 0.56m/s, which is calculated to be about 8.88m3/h。
2. Water intake of air water collector
Three modified hydrophilic fillers are respectively filled in the air water collecting device, the water collecting amount is tested under the same environmental condition, and fig. 8 shows the actual water collecting condition of the three different modified hydrophilic fillers in the air water collecting device.
It can be seen from fig. 8 that three different hydrophilic fillers, namely the modified polyester mesh, the modified stainless steel mesh and the modified polypropylene mesh, respectively collect 35.7ml, 56.4ml and 47.1ml of water in the same environment on average each day, which can basically solve the problem of low drought survival rate of local plants, and can play a role in protecting plant breeding and growth, thereby achieving the purpose of improving the local ecological environment.
