Embodiment Construction

[0054] figure 1 For the schematic diagram of implementing the wavy water vapor condensation surface, the hydrophilic raised parts 1 and the hydrophobic lowered parts 2 are alternately arranged. The hydrophilic protruding part is covered with a hydrophilic material layer to capture water vapor in the air; the hydrophobic low concave part is used to transfer the water vapor captured by the hydrophilic protruding part because of its hydrophobicity.

[0055] figure 2 It is a preferred version of the present invention, wherein the shape of the water vapor condensation surface is a wavy hemispherical surface, and polytetrafluoroethylene is used as the water vapor condensation surface substrate, and polytetrafluoroethylene is both a hydrophobic material and a radiation refrigeration material; the hydrophilicity of the water vapor condensation surface The protruding portion is covered with a hydrophilic material layer, and the hydrophilic coating used in this specific implementation...

Abstract

The invention discloses a moisture capture device. The moisture capture device comprises a wave-shaped moisture condensation surface and a water storage device, wherein a radiation refrigeration material serves as a base plate of the moisture condensation surface, protruding portions of the wave-shaped moisture condensation surface are hydrophilic protruding portions, concave portions of the wave-shaped moisture condensation surface are hydrophobic concave portions, the water storage device is arranged at the bottom end of the moisture condensation surface, and droplets are formed by moisture captured by hydrophilic protruding portions, then transferred to hydrophobic concave portions after growing up and transferred to the water storage device along hydrophobic concave portions. The temperature of the condensation surface can be reduced quickly due to the radiation refrigeration material, the moisture in the air is captured by hydrophilic protruding portions and is condensed into droplets, and droplets are transferred to hydrophobic concave portions after growing up and are quickly transferred to the water storage device along hydrophobic concave portions. The device is simple in structure and environment-friendly, can be used in arid areas and semi-arid areas to mitigate the problem of water shortage to a certain extent and can be used in non-arid areas to provide domestic water and production water.

Description

technical field [0001] The invention relates to a water vapor capture device, which can convert water vapor in the air into liquid fresh water. Background technique [0002] Water is the source of life. It nourishes all things in the world. Without water, there would be no life, and there would be no human beings. Although the earth is called a "water polo", the proportion of liquid fresh water that can be directly used by human beings is very small, and with the rapid development of human society, the available liquid fresh water resources are increasingly unable to meet human needs. [0003] Faced with the severe water shortage problem, human beings have proposed many solutions: seawater desalination, artificial rainfall, multiple recycling of water, etc. These technologies have different constraints, such as: desalination of seawater can only be carried out in some coastal areas, in addition, the technology is not mature enough and the cost is high; artificial rainfall m...
