Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with specific examples.

[0033] Such as figure 1 As shown, the solar seawater desalination device includes a container 5 , a water-absorbing material 2 , an insulating block 3 , an alcohol wick 4 and a black light-absorbing material 1 . The container 5 is a cylinder with an open top, and the bottom is filled with seawater or artificial seawater to wait for the evaporated liquid 6, and the container 5 can be a cylindrical transparent glass.

[0034] Such as figure 2 As shown, the black light-absorbing material 1 can be adsorbed on the water-absorbing material 2 by spin coating, spray coating or suction filtration, etc. The water-absorbing material 2 can be dust-free paper, and the black light-absorbing material 1 is formed into a certain shape, preferably a circle. Black light-absorbing material 1 is selected from carbon black powder, black TiO x powder or black MoS 2 powder. One end of...

Abstract

The invention relates to a solar-powered seawater desalination device based on gas-liquid interface heating and its application. The device includes: a container for storing seawater; a heat-insulating block clamped on the inner wall of the container; and a water-absorbing material arranged on the heat-insulating block ; a black light-absorbing material adsorbed on the water-absorbing material; and a water-absorbing mechanism for delivering seawater to the water-absorbing material. The device could increase the rate of solar desalination.

Description

technical field [0001] The invention belongs to the field of solar seawater desalination, in particular to a solar seawater desalination device based on gas-liquid interface heating and its application. Background technique [0002] With the rapid development of industry and agriculture in society and the rapid increase of population, people's demand for water resources is increasing day by day. At the same time, the problem of water pollution has become more serious, which makes the already scarce clean and safe fresh water resources even more scarce. [0003] At present, effective methods to solve the shortage of fresh water resources are seawater desalination, long-distance water transportation, and recycling of water resources (sewage and wastewater). Compared with the other two methods, seawater desalination can provide sufficient water volume and high-quality water quality, and has been adopted by more and more countries in recent years. [0004] The traditional seaw...
