Sea island power supply system with combination of sea island microgrid peak regulation and seawater desalination

Abstract

The invention discloses a sea island power supply system with combination of sea island microgrid peak regulation and seawater desalination. The system comprises a heat pump system, an air system, a water system and a microgrid system, wherein the water system is used for taking seawater in a water storage tank for preheating and spraying so as to guide water circulation in a precooler; the air system is used for conveying air and ensuring set parameters of the inlet air; the heat pump system is used for treating heat and humidity of the air flowing through the heat pump system and reducing temperature and humidity of an evaporator to obtain fresh water; the microgrid system is used for supplying power to a compressor, a water pump and a fan. An evaporative condenser is used as a heat source for desalinating the seawater; on the one hand, an external heating source is not needed, so that the system can be independently used, and the devices are simple and are easy to operate and manage; on the other hand, the system is capable of producing fresh water at low condensation temperature of 30-40 DEG C; the condensation temperature is lower than the condensation temperature of the conventional steam compression type refrigerator, so that COP of the whole machine is greatly improved; after the desalinated seawater and the collected rainwater are treated, the supply of drinking water and domestic water can be completed.

Description

technical field [0001] The invention relates to an island water supply system, in particular to an island water supply system combining peak regulation of an island microgrid and seawater desalination. Background technique [0002] There are many uninhabited islands in my country's territorial waters. These islands are located in special locations. They are surrounded by rich marine resources such as organisms, ports, oil and gas, minerals, and ocean energy. They have high development and utilization values ​​in military affairs, scientific research, and tourism. . Working and living in the extreme environment of isolated islands, the three most important aspects are power supply, thermal and humid environment control, drinking fresh water and domestic water supply. The resources of the island are characterized by abundant solar and wind energy resources, so the wind-solar-diesel-storage hybrid power generation system can be used to solve the power supply; and the island has...
