Abstract
The invention belongs to the technical field of water treatment, and particularly relates to a multi-mode water purification system based on a humidifying and dehumidifying process. The system mainlycomprises a Carnot circulation loop, a porous material, an axial flow fan and a box body. The Carnot circulation loop is composed of a compressor, a radiator, an expansion valve and a condenser. The porous material, the radiator, the axial flow fan and the condenser are placed in the adjustable box body, the porous material is closely attached to the radiator, doors on the two sides of the adjustable box body can be opened, and the system can achieve clean water preparation and waste water concentration in three modes. According to the multi-mode water purification system based on the humidifying and dehumidifying process, the concentrated solution is obtained by heating and evaporating the wastewater, and the clean water is obtained by evaporating the water vapor or condensing the water vapor in the air. The multi-mode water purification system disclosed by the invention has important significance for clean water preparation and application in various environments, is easy to work inseries, and can be applied to clean water preparation in a full-range humidity range.
Description
technical field [0001] The invention belongs to the technical field of water treatment, in particular to a multi-mode water purification system based on a humidification and dehumidification process. Background technique [0002] With the development of social economy and the increase of population, the scarcity of fresh water resources has gradually become the second largest environmental problem in the world after global warming. Studies have shown that it is estimated that by 2025, nearly one-third of the world's population will be short of water. In order to ensure the healthy and sustainable development of human society, in addition to scientific management of water resources such as water conservation, the development of new water treatment technologies such as seawater desalination and sewage treatment and reuse has gradually become a solution. The mainstream technologies such as thermal distillation, reverse osmosis and electrodialysis have gradually formed. The cu...
