Abstract

The invention discloses a self-gravity water inlet heat regeneration type liquid film evaporation type solar seawater distillation device. The device comprises a flat-plate solar collector A, a concentrated seawater collection tank, a fresh water collection tank, a water distributor, a flow control valve, a seawater feeding pipe, a glass cover plate, an overflow pipe, a preheated seawater cylinder, a hot water inlet pipe A, a heating water tank, a condensation sleeve A, a water absorption material, a water baffle, a concentrated seawater collection pipe, a water return pipe, a hot water inletpipe B, a bottom plate and a fresh water collection pipe. According to the invention, the preheated seawater cylinder and a saline water separation part are combined into one, self-gravity water feeding of seawater can be realized by utilizing potential energy of the seawater to save the power driving energy consumption, the solar energy absorbed by the preheating seawater cylinder is absorbed byseawater, the water inlet temperature is increased, latent heat of condensation released by water vapor in the seawater feeding pipe during condensation is also absorbed by seawater in the seawater feeding pipe, condensation of the water vapor is promoted, and the water production rate of the seawater distillation device is increased.

Description

technical field [0001] The invention relates to the technical field of solar seawater desalination and water treatment, in particular to a liquid film evaporation solar seawater distillation device of self-gravity water inlet and heat recovery type. Background technique [0002] Safe and sufficient drinking fresh water is an important guarantee for human health. The World Health Organization recommends that adults drink 2.0L of fresh water per day. It is difficult for active personnel to obtain fresh water anytime and anywhere. In addition, the basic support conditions such as transportation, electricity, and technology in water-scarce areas are lacking. Large-scale seawater or brackish water desalination systems cannot meet the above-mentioned freshwater preparation requirements. Given that freshwater-scarce areas often have abundant solar energy resources, it is entirely possible to use solar energy to drive small seawater desalination devices to achieve local water intake...
