Abstract

The invention discloses a radiation refrigeration water resource obtaining device. The radiation refrigeration water resource obtaining device comprises an evaporation chamber, a condensation chamber and a communicating device, wherein the evaporation chamber communicates with the condensation chamber through the communicating device, a radiation refrigeration coating is arranged in the condensation chamber to accelerate water vapor condensation, the radiation refrigeration coating comprises at least one kind of inorganic particles with high reflectivity and at least one kind of high-molecular polymer, the surface of the radiation refrigeration coating comprises hydrophilic areas and hydrophobic areas, and the hydrophilic areas and the hydrophobic areas are arranged in a staggered mode. According to the radiation refrigeration water resource obtaining device provided by the invention, the specific radiation refrigeration coating is arranged in the condensation chamber, so that the surface temperature of the radiation refrigeration coating is far lower than the air temperature, the temperature difference required for condensing water vapor is provided enough, and the condensation efficiency is further improved.

Description

technical field [0001] The invention relates to a radiation refrigeration water resource acquisition device, which belongs to the technical field of fresh water resource acquisition. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources, which can increase the total amount of fresh water without being affected by time, space and climate, and can guarantee stable water supply such as drinking water for coastal residents and replenishment water for industrial boilers. The process of obtaining fresh water from sea water is called desalination. Currently used seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. At present, the application of reverse osmosis membrane method and distillation method is the mainstr...
