Abstract

The invention provides a solar water desalination system based on a carbon composite material hollow fiber membrane, and a method thereof. The desalinated water system comprises: a membrane assembly,which is provided with a water inlet, a water outlet and a steam outlet, wherein the water inlet and the water outlet are connected with a to-be-treated working medium and form a circulating system with the to-be-treated working medium, the membrane assembly is used for absorbing solar energy to heat the working medium in the membrane assembly into steam, and the steam flows out through the steamoutlet; a condensed water tank connected with the steam outlet, wherein an S-shaped coil pipe is arranged in the condensed water tank, and the condensed water tank is used for cooling steam into condensed water; and a condensed water collecting bottle connected with the condensed water tank and used for collecting the condensed water cooled by the condensed water tank. The system has the advantages of low cost, simple structure and high efficiency, and is suitable for daily desalination requirements of coastal residents or fishermen.

Description

technical field [0001] The present invention mainly relates to the technical field of desalinated water, specifically a solar desalination water system based on carbon composite hollow fiber membranes, and also relates to a seawater desalination method, specifically a method for preparing fresh water by using solar membrane distillation to desalinate seawater , belongs to water desalination technology. Background technique [0002] Under the background of economic globalization and the vigorous development of low-carbon economy in various countries, clean energy has been paid more and more attention. Although China is a big energy-consuming country, it has abundant solar energy resources. It is estimated that the annual solar radiation received by the land surface of our country is about 50×10 18 kJ, the total annual solar radiation across the country reaches 335-837kJ / cm 2 a, the median value is 586kJ / cm 2 a. Looking at the distribution of total annual solar radiation ...
