Self-adaptive solar seawater desalination device

Abstract

The invention relates to a self-adaptive solar seawater desalination device, comprising a case and a seawater tank arranged in the case, wherein a transparent cover is arranged above the case, and anevaporation tank is formed between the transparent cover and the case. The seawater desalination device further comprises a plurality of circulating evaporation assemblies, wherein each circulating evaporation assembly comprises an upper rotating wheel, a lower rotating wheel and a non-woven fabric surrounding the upper rotating wheel and the lower rotating wheel. Seawater is contained in the lower part of the seawater tank; the lower rotating wheels are partially or completely immersed in the seawater; the upper shell of the seawater tank is provided with evaporation windows corresponding tothe mounting positions of the upper rotating wheels; the upper parts of the upper rotating wheels extend out of the evaporation windows and are positioned in the evaporation tank; and the non-woven fabric serves as a carrier of an evaporation medium and surrounds the two corresponding rotating wheels to rotate at a constant speed or in a stepping mode according to design requirements. According tothe invention, seawater desalination circulation reciprocating process is achieved through the circulating evaporation assemblies, working efficiency is further improved through forced condensation circulation design, and the device does not need external energy input or external operation mode adjustment.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to an adaptive solar seawater desalination device. Background technique [0002] The depletion of drinking water resources and the deterioration of sanitation conditions are one of the serious challenges facing human beings around the world. It is predicted that by 2025, half of the countries in the world will face the severe situation of fresh water shortage, and by 2050, 75% of the world's population will face the plight of water shortage. Therefore, it is very important to improve the water supply capacity and develop disinfection and purification technology. At present, in the fields of water resource purification and seawater desalination, reverse osmosis membrane separation technology occupies a dominant position. However, this method is not only costly, but also has a relatively large impact on the environment. Therefore, it is necessary to develop a water pu...
