Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, the solar desalination device of the present invention is composed of an air circulation system, a seawater treatment system, a solar heating system and a fresh water collection system.

[0020] Air circulation system: the outlet end of the fan 5 is connected to one end of the seawater condensation box 6, the other end of the seawater condensation box 6 is connected to one end of the air duct 7, the other end of the air duct 7 is connected to one end of the adsorber 3, and the other end of the adsorber 3 is connected to the seawater evaporation box 4 are connected at one end, and the other end of the seawater evaporation box 4 is connected with the inlet end of the fan 5 . The low-temperature saturated air sent from the seawater condensing tank 6 passes through the air pipe 7, and then is sent to the...

Abstract

The invention discloses a solar seawater desalination plant and an operation method thereof, belonging to the technical field of seawater desalination. The plant mainly consists of an air circulation system, a seawater treatment system, a solar heating system, a fresh water collecting system and the like. According to the invention, saturated air generates fresh water in a large temperature difference range through humidifying air with hot seawater and then dehumidifying the air with cold seawater by virtue of an adsorption type air water taking device and a saturated air humidifying and dehumidifying type solar distillation device, and simultaneously, cold air generates fresh water in a small temperature difference range through adsorption and desorption processes, thereby utilizing the moisture content of the air to the greatest extent, realizing the generation of fresh water by using air in the full temperature difference range and a full humidity range, effectively improving the fresh water yield of air flow per unit and improving the property index of the whole system.

Description

technical field [0001] The invention relates to a solar-powered seawater desalination device and an operating method thereof, belonging to the technical field of seawater desalination and air-conditioning refrigeration. Background technique [0002] Water is of great significance to the survival and development of human beings, but the fresh water resources that can be used by human beings only account for 0.77% of the total global water reserves. Ocean water accounts for 96.5% of the world's total water reserves, and nearly 70% of humans live less than 120 kilometers from the sea. Due to the shortage of terrestrial freshwater resources, desalination of seawater has been paid more and more attention to by coastal countries in the world. [0003] Commonly used seawater desalination methods such as distillation, ion exchange, electrodialysis, reverse osmosis membrane, etc., consume a lot of electricity and fuel. Solar seawater desalination technology has gradually attracted ...
