Seawater evaporation and desalination system

Abstract

The invention belongs to the technical field of seawater desalination equipment and in particular relates to a seawater evaporation and desalination system. The seawater evaporation and desalination system comprises a bottom plate, a fixed frame, a collection frame, a desalination frame, a solar heat collection plate, a water collection groove and a water storage chamber, wherein the fixed frame is mounted on the bottom plate; the lower end of the fixed frame is embedded into the bottom plate; the lower end of the collection frame is embedded into the bottom plate; the collection frame is located at the left side of the fixed frame; the desalination frame is mounted above the fixed frame; the desalination frame is used for sealing the fixed frame; the desalination frame is provided with aglass cover plate; a through hole is formed in the bottom of the right side of the desalination frame; a No. 1 flow guide pipe is arranged between the collection frame and the desalination frame; thesolar heat collection plate is L-shaped; the solar heat collection plate is mounted in the desalination frame through a spring; the solar heat collection plate is used for sealing the through hole inthe desalination frame; the water collection groove is mounted on an inner wall of the right side of the desalination frame; the water storage chamber is located at the right side of the desalinationframe; a No. 2 flow guide pipe is further arranged between the water storage chamber and the water collection groove.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination equipment, in particular to a seawater evaporation and desalination system. Background technique [0002] The shortage of fresh water resources has always been a problem faced by human beings, especially in remote mountainous areas and islands where electricity is scarce. Solar seawater desalination technology is of great significance to solve the desalination of brackish water in islands with shortage of freshwater resources, remote water-scarce areas and inaccessible power resources. However, the existing seawater desalination device is greatly affected by the intensity of sunlight when utilizing solar energy, cannot obtain enough solar energy to heat seawater, the evaporation rate of seawater is not high, and the output of desalinated seawater is low.

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned Patent Document 1, the raw seawater is heated by using the waste heat in the remaining concentrated seawater after desalination, so as to increase the inlet temperature of the seawater and speed up the evaporation rate. Solve the problem of low solar energy collection efficiency, seawater desalination efficiency is not high, and desalinated seawater output is low
