Solar photovoltaic salt production comprehensive utilization system

Abstract

The invention discloses a solar photovoltaic salt production comprehensive utilization system. The invention aims at providing a system which not only can produce salt, but also can generate electricpower, and can increase the utilization rate of energy. A salt pan is provided with a chimney and a photovoltaic heat collector, and the top of the chimney is provided with a condensation heat exchanging apparatus; the photovoltaic heat collector comprises a roof formed by closely connecting a plurality of photovoltaic modules and a support, the roof is supported by the support, a heat collector entrance is formed between the edge of the roof and the salt pan, one side of the condensation heat exchanging apparatus is provided with an air guide port, an air outlet of the air guide port is separately connected with inlets of an exhaust pipeline and a regenerative pipeline by virtue of a three-way valve, and an outlet of the regenerative pipeline is communicated with the interior of the photovoltaic heat collector; and the lower end of the condensation heat exchanging apparatus is provided with a water collection disc, and the water collection disc is connected with a hydraulic turbine generator. The solar photovoltaic salt production comprehensive utilization system can utilize the photovoltaic modules to generate electric power at daytime; and meanwhile, the waste heat generated bythe photovoltaic power generation can heat the air in the photovoltaic heat collector and the salt pan, so that the salt production effect of the salt pan can be improved, and the utilization rate ofthe energy is greatly increased.

Description

technical field [0001] The invention relates to the technical field of salt production, and more specifically relates to a comprehensive utilization system for solar photovoltaic 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 which the brine temperat...

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
