Seawater desalination device and system with wind-solar complementary coupling

Abstract

The invention provides a wind and light complementary coupling sea water desalting device and a wind and light complementary coupling sea water desalting system. The wind and light complementary coupling sea water desalting device and the wind and light complementary coupling sea water desalting system can adapt to fluctuant solar energy and wind energy to carry out variable load operation and remarkably improve the sea water desalting efficiency. The sea water desalting device provided by the invention is characterized by comprising a solar capillary driving evaporator, a gas compressor and a fresh water collector, wherein the solar capillary driving evaporator comprises a shell, a solar capillary evaporation core positioned in the shell and a heat exchange tube; the solar capillary evaporation core is arranged in the middle of the shell; the heat exchange tube is embedded in the solar capillary evaporation core; the shell is divided into an upper cavity and a lower cavity by the solar capillary evaporation core; the lower cavity serves as a sea water compensation chamber to store the supplemented to-be-evaporated sea water, and the evaporated concentrated salt water is discharged by a salt water discharge pipeline; the upper cavity serves as a vapor chamber to collect primary vapor; the gas compressor is connected with a wind machine through a connecting rod and is connected with the vapor chamber through a primary vapor pipeline; an exhaust port is connected with the gas inlet end of the heat exchange tube through a secondary vapor pipeline; and the fresh water collector is connected with a water discharge port of the heat exchange tube.

Description

technical field [0001] The invention belongs to the field of seawater desalination and clean energy utilization, and in particular relates to a seawater desalination device and system based on complementary coupling of wind energy and solar energy. Background technique [0002] my country's territory is adjacent to the Pacific Ocean, with a coastline of more than 18,000 kilometers and nearly 10,000 islands in the sea area under its jurisdiction. Restricted by factors such as nature, climate and transportation, the utilization rate of these islands is very low. Among them, the islands are small in size and low in evaporation, and most of them cannot be inhabited and developed due to lack of fresh water. Some developed islands can only be resupplied with fresh water by means of water diversion from mainland pipelines and drinking water delivered by boats. Making full use of seawater desalination for fresh water recharge is one of the effective ways to solve the fresh water r...
