Comprehensive utilization system of concentrating solar photovoltaic generation and water purification

Abstract

The invention relates to the technical field of solar utilization and particularly relates to a comprehensive utilization system of concentrating solar photovoltaic generation and water purification. The system consists of a condenser, a dirty water tank, a clean water tank, a combined receiving device for supplying electric energy and treating dirty water to supply clean water, pipelines for connecting the dirty water tank, the combined receiving device and the clean water tank, a water pump for driving the dirty water to enter the combined receiving device to be treated, and an electrode lead for outputting electric energy generated by a condensation solar battery in the combined receiving device. The system provided by the invention utilizes the condensation solar battery to efficiently respond the wave band of sun light to generate power, and simultaneously reuses the ultraviolet wave band of the sun light to treat the dirty water, so that the solar energy can be economically, efficiently and comprehensively used. Furthermore, the problem that generation efficiency is decreased due to temperature rising of the condensation battery, which is caused by radiation in a non-response range or a low-efficiency response wave band, can be avoided; more energy sources can be obtained at the same cost of the condensation system, so that the energy cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a comprehensive utilization system for concentrated solar photovoltaic power generation and water purification. Background technique [0002] In the 21st century, human beings have an increasing demand for clean energy and clean water, but obtaining these resources is facing huge technical challenges, especially for a populous country like China, where electricity and clean water are becoming increasingly scarce. Using solar energy It has become an important subject of research to generate electricity and supply pure water at the same time. [0003] Solar photovoltaic power generation is the fastest-growing and most dynamic research field among the many utilization methods of solar energy in recent years; however, due to the lack of competitive installation costs and on-grid electricity prices, the photovoltaic industry has not achieved rapid development. High e...
