Abstract

The invention discloses a micro-structure condensation cloth for all-weather water collection, which is characterized in that the micro-structure condensation cloth overcomes gravity to realize continuous directional water transportation on the premise of not consuming extra energy by constructing a microscopic spine structure on the surface of a fiber prepared from a radiation refrigeration composite material, so that all-weather condensed water collection is realized. Compared with the prior art, the micro-structure condensation cloth not only has the functional characteristics of excellent directional water transportation capacity, radiation refrigeration performance and the like, but also has the excellent structural characteristics of softness, light weight, large surface area and the like, and a condensation device with a controllable shape and structure can be constructed; a user can design different structures according to actual requirements so as to adapt to complex application requirements of multiple scenes. The method can be applied to areas where available surface water resources are deficient due to drought, semi-drought, water pollution, water and soil loss and the like, the problem of water shortage can be relieved to a certain extent, and a candidate choice is provided for production and domestic water.

Description

Technical field [0001] The present invention relates to the field of radiation refrigeration, and more particularly to a microstructure condensation collected 244. Background technique [0002] Atmosphere can be considered a huge renewable reservoir, can act as a water source anywhere on the earth. The water in the air is estimated 14000km 3 And the amount of fresh water on the earth is about 1200km 3 . Dew is a water droplets formed by the atmospheric water vapor at a surface condensed below the dew point temperature. Dew can be seen as an unconventional water source, which is a region where climatic conditions are contemplated, lack of water supply and water quality. [0003] Although there are many weather conditions facilitating the formation of dew, potential extraction is large, but the existing dew collect system has a low water-saving efficiency, which indicates that dew collection is a non-developing offer. Alternative to high quality water. [0004] Radiation (also know...
