Abstract

The invention discloses a solar concentrating distillation seawater desalination device comprising a light-transmitting plate, a side plate and a base plate, wherein a heat storage chamber top plate and a heat storage chamber base plate are arranged on the inner surface of the side plate, and a heat storage material is arranged between the heat storage chamber top plate and the heat storage chamber base plate; an evaporation chamber is arranged above the heat storage chamber top plate; a condensation chamber is arranged below the heat storage chamber base plate; a baffle plate is arranged in the condensation chamber; a fresh water outlet is formed in the lower part of the side plate; an upper opening of a non-condensable gas pipeline is formed in the evaporation chamber, and a lower opening of the non-condensable gas pipeline is positioned in the condensation chamber; an air draft fan is arranged at the upper part of the evaporation chamber and is positioned in an opening of a steam pipeline, and the other opening of the steam pipeline is positioned in the condensation chamber; a seawater inlet and a strong brine outlet are formed in the side plate; the lower end of a solar concentrating plate is connected with the top of the side plate; a rainwater collecting opening is formed in the bottom of the solar concentrating plate; a solar cell panel is connected with a charging controller, a storage battery and the air draft fan respectively through a lead. The solar concentrating distillation seawater desalination device is high in solar thermal utilization efficiency and long in water production time, and can realize stable water production by completely depending on solar energy.

Description

Technical field [0001] The invention belongs to the technical field of solar seawater desalination, and relates to a solar concentrating type distillation seawater desalination device. technical background [0002] my country's water shortage situation is severe. With population growth and economic and social development, the shortage of water resources has become an urgent problem to be solved in the current society, such as water for residents in remote areas such as deserts and islands, emergency fresh water for field work, and fresh water intake by wild animals. Seawater desalination is a method of using seawater desalination to produce fresh water. Commonly used seawater desalination methods include distillation, reverse osmosis, etc. These methods have high energy consumption, and energy supply in these remote areas is usually difficult, but solar energy resources are abundant. Therefore, the use of solar energy for desalination of seawater or brackish water is an importan...
