An integrated device for solar temperature difference power generation and air water intake applied to small islands and reefs

Abstract

The invention provides a solar thermoelectric power generation and air water taking integration device applied to small islands and reefs, which comprises a trough solar energy heat collection unit, an integrated main unit, an automatic water supplementing unit, a humidifying and pre-cooling unit and a power storage and supply unit, wherein the trough solar energy heat collection unit is used forheating a heat transfer medium to enable the heat transfer medium to rise in temperature and keeping a preset temperature; the integrated main unit is used for thermoelectric power generation and airwater taking; the automatic water supplementing unit is used for supplementing seawater evaporation in an open water tank; the humidifying and pre-cooling unit is used for enabling wet air coming froma humidifying chamber and non-condensable air coming from a condensation chamber to carry out heat exchange and pre-cooling in a pre-cooler; and the power storage and supply unit stores electric energy generated by thermoelectric power generation in a power storage device and is used for supplying power to electrical equipment on the small islands and reefs and serving as an electric energy source of condensation water taking at night. The solar thermoelectric power generation and air water taking integration device carries out solar energy thermoelectric power generation by using a Seebeck effect during the day and stores the generated electric energy into the power storage device; and the air humidity turns high at night, the wet air is condensed by using a Peltier effect to provide fresh water. The solar thermoelectric power generation and air water taking integration device is clean and pollution-free, and has important significance for marine ecology and environment protection.

Description

technical field [0001] The invention relates to the technical fields of multi-energy complementarity and renewable energy utilization, thermoelectric power generation, and thermoelectric refrigeration. Specifically, it relates to an integrated device for solar thermoelectric power generation and air water intake applied to small islands and reefs. Background technique [0002] my country is a large oceanic country with a vast ocean area. With the improvement of marine awareness in various countries in the world today, the development of the ocean and the protection of marine rights and interests have attracted increasing attention. The islands and reefs in the ocean are the frontiers for safeguarding marine rights and interests. At present, there are many small islands and reefs in my country. The land area is small and remote, which can only accommodate few people or are not suitable for human habitation. For example, rocks and reefs in the ocean cannot sustain human habitat...

Problems solved by technology

However, the general functions of existing devices are mostly power generation or fresh water production, and the function is too single to solve the problem of shortage of power and fresh water at the same time.

At the same time, the amount of installation work is large, the cost is high, and it has a certain impact on the marine environment around the islands and reefs
