Abstract

The invention discloses a reinforced convection heat transfer type solar distillation sea water desalting device which comprises a light-transmitting plate, a side plate and a bottom plate, wherein the upper part of the side plate is provided with a condensation water collection tank and a condensation water outlet; the inner surface of the side plate is provided with a heat storage chamber top plate and a heat storage chamber bottom plate; a heat storage material is arranged between the heat storage chamber top plate and the heat storage chamber bottom plate; an evaporation chamber is arranged above the heat storage chamber top plate; a condensation chamber is arranged below the heat storage chamber bottom plate; a baffle plate is arranged in the condensation chamber; the lower part of the side plate is provided with a fresh water outlet; the upper end opening of a noncondensable gas pipeline is arranged in the evaporation chamber, and the lower end opening is positioned in the condensation chamber above the fresh water outlet; an induced draft fan is arranged at the upper part of the evaporation chamber and positioned in one end opening of a steam pipeline; the other end opening of the steam pipeline is arranged at the upper part of the side plate positioned in the condensation chamber; and the side plate positioned in the evaporation chamber is respectively provided with a sea water inlet and a strong brine outlet. According to the invention, convection heat transfer is reinforced by the induced draft fan, the evaporation / condensation rate is high, and the steam condensation latent heat recovery / solar heat utilization efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of solar seawater desalination, and relates to an enhanced convection heat exchange solar distillation seawater desalination device. technical background [0002] my country's water shortage situation is severe. With the growth of population and the continuous development of economy and society, the shortage of water resources has become an urgent problem to be solved in the current society. Desalination of seawater is a method of producing fresh water by desalination of seawater. Commonly used desalination methods include distillation, reverse osmosis, etc. These methods consume high energy consumption, and energy supply in these remote areas is usually difficult, but solar resources are abundant. Therefore, using solar energy to desalinate seawater or brackish water is an important way to solve the shortage of freshwater resources in these areas. [0003] The unfavorable factors such as low water product...
