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

technical field [0001] The invention relates to a device for promoting the large-scale and low-cost application of a solar seawater desalination device, which belongs to the technical fields of solar heat utilization, seawater desalination and water treatment. Specifically, it relates to a seawater evaporator which improves the freshwater production capacity of a solar seawater desalination device and reduces the cost of freshwater. Background technique [0002] The shortage of fresh water resources is one of the severe challenges facing the world at present. The best solution is to develop and utilize the existing earth's water cycle system. Considering energy saving, environmental protection, construction cost and operating cost, the use of solar energy for seawater desalination is becoming more and more popular. attention. Existing solar desalination devices have defects such as large one-time investment, small scale, and low efficiency. weakness. This is mainly due to...
