Comprehensive solar photovoltaic power generation and salt preparation system

Abstract

The invention discloses a comprehensive solar photovoltaic power generation and salt preparation system and aims at providing a salt preparation system which can utilize solar concentrating for powergeneration, prepare salt, achieves comprehensive utilization of solar energy and increase an energy utilization rate. A chimney and a transparent heat collection shed are arranged on a salt pan; a condensation heat exchange device is arranged on the chimney; a light condensation photovoltaic system is arranged below the transparent heat collection shed and comprises a plurality of light condensation modules, light condensation photovoltaic batteries, battery cooling pipelines and brackets; the back surfaces of the light condensation photovoltaic batteries are clung to the battery cooling pipelines; the front surfaces of the light condensation photovoltaic batteries are in contact with air; the battery cooling pipelines, overground heat exchange pipes, underground heat exchange pipes and circulating pumps are sequentially connected to form enclosed cooling and heat exchange circulation pipelines; and a heat collection shed inlet is formed between the edge of the transparent heat collection shed and the salt pan. The photovoltaic power generation efficiency of the system is greatly improved; at the same time, the evaporation of water in the salt pan is intensified; and a salt preparation effect of the salt pan is improved.

Description

technical field [0001] The invention relates to the technical field of salt production, and more specifically relates to a comprehensive utilization system of solar photovoltaic power generation and salt production. Background technique [0002] With the continuous development of global urbanization and industrialization, the shortage of energy and water resources in my country and some countries has become more and more prominent, which has seriously affected the development of national economy. Salt is indispensable in human life. my country has a long coastline, and the use of seawater to make salt has a long history in my country. However, at present, the salt production technology is mainly to produce salt by sun-dried salt. In recent years, the method and process of salt production through solar greenhouses have gradually received attention and development. The solar greenhouse salt production method is mainly to establish a qualified closed greenhouse, through whic...

AI Technical Summary

Problems solved by technology

The method of solar greenhouse salt production is mainly to establish a qualified closed greenhouse, through which the temperature of brine in the greenhouse is increased, and the evaporation of water is accelerated to increase the speed of salt production. However, there are also some utilization problems in solar greenhouse salt production, such as The overall low utilization rate of solar energy and the inability to produce salt at night lead to low overall economic benefits of engineering application of solar salt production technology, which limits the further development of this technology
