Problems solved by technology

In recent years, many water cleaning technologies for interfacial photothermal conversion materials have been developed. However, impurities in sewage are easy to damage the photothermal conversion interface or directly adhere to its surface, which greatly limits the application of water cleaning technologies based on interfacial photothermal conversion materials. Sustainable development; the evaporation efficiency of sewage is low, which increases the cost of water cleaning technology for interface photothermal conversion materials, and the high impurity content in sewage accelerates the damage to solar photothermal conversion materials, reducing the efficiency of solar photothermal conversion materials. service life

Abstract

The invention relates to a water cleaning system based on rolling droplet surface evaporation, comprising a photothermal superhydrophobic surface; the photothermal superhydrophobic surface is a structure arranged in a spiral downward and its lower end is folded inward, and the photothermal superhydrophobic surface The outer side is provided with a track for sewage droplets to slide down, a light-transmitting condensation cover is arranged on the outer side above the light-thermal super-hydrophobic surface, and the upper side of the light-transmitting condensation cover is a semicircular shell structure, and the light-transmitting condensation cover The lower end of the cover is engaged with a clean water collection container. The invention can solve the existing problems when the interface photothermal conversion material is used to obtain clean water: impurities in the sewage are easy to damage the photothermal conversion interface or directly adhere to its surface, which greatly limits the water cleaning technology based on the interface photothermal conversion material. The sustainable development of sewage; the low efficiency of sewage evaporation, and the increase of the cost of water cleaning technology for interface photothermal conversion materials.

Description

technical field [0001] The invention relates to the technical field of solar water treatment based on photothermal interface, in particular to a water cleaning system based on surface evaporation of rolling droplets. Background technique [0002] Water is the source of life. It is estimated that by 2050, 3.5 to 4.4 billion people in the world will face shortage of fresh water resources. Existing clean water production technologies are facing problems such as power consumption and materials are prone to aging, so the prospect of large-scale and sustainable clean water production is still unclear. Therefore, it is necessary to further develop sustainable clean water resource acquisition technologies. Compared with the scarce clean fresh water resources, most of the water resources on the earth are seawater, domestic industrial wastewater and other sewage that cannot be directly drunk. It is very important to obtain clean fresh water from sewage. [0003] The sun is the oldest...
