Seawater evaporator for light collecting solar seawater desalination device

Abstract

The invention provides a seawater evaporator for a light collecting solar seawater desalination device. The seawater evaporator comprises a transparent tube, a spill net, ceramic grains, fins and partition baffles; openings are respectively formed in the upper end and the lower end of the transparent tube; grooves are distributed in the inner surface of the transparent tube; the external diameterof each partition baffle is identical to the internal diameter of the transparent tube; a through hole is formed in the center of the partition baffle; a deflector hole is formed in the edge of the partition baffle; the spill net is mounted at the opening at the upper end of the transparent tube; the partition baffle is arranged in the inner chamber of the transparent tube; two adjacent layers ofpartition baffles, the upper layer of partition baffle and the spill net form a chamber; the volume of the chamber is decreased progressively in sequence from the top down; the fin is arranged on theupper end surface of each layer of partition baffle; and the ceramic grain is arranged on the upper end surface of each layer of partition baffle and put between the fins. The seawater evaporator achieves the seawater functionalization, also enhances the seawater light absorption function and the scale removal and inhibition function, can also be applied to the solar seawater desalination device,and improves the efficiency of using heat energy by the solar seawater desalination device.

Description

Problems solved by technology

Existing solar desalination devices have defects such as large one-time investment, small scale, and low efficiency. weakness

This is mainly due to the structural mismatch between the low efficiency of the solar thermal collection system in the high temperature range (≥100°C) and the low efficiency of the seawater desalination components in the low temperature range
