Solar photovoltaic chimney salt-making system

Abstract

The invention discloses a solar photovoltaic chimney salt-making system, aiming at providing a salt-making system which can comprehensively utilize solar energy so as to increase energy utilization rate. A chimney and a photovoltaic heat collecting shed are arranged on a salt field, and a condensing heat exchanger is arranged on the chimney; the photovoltaic heat collecting shed comprises a shed roof formed by a plurality of photovoltaic modules which are closely connected together, and a support; the shed roof is supported by the support; an entrance of the heat collecting shed is formed between the edge of the shed roof and the salt field; an air guide hole is formed at one side of the condensing heat exchanger, and an air outlet of the air guide hole is separately connected with an exhaust duct and an inlet of a heat return pipeline by means of a three-way valve; an outlet of the heat return pipeline is communicated with the interior of the photovoltaic heat collecting shed. The system provided by the invention can utilize the photovoltaic modules for photovoltaic power generation during the daytime, and the waste heat generated by the photovoltaic power generation can be used for heating the air in the photovoltaic heat collecting shed and the salt field, so that the salt production effect of the salt field is improved. Furthermore, the condensing heat exchanger at the bottom of the chimney can produce a large amount of fresh water for industrial and domestic use, so that the energy utilization rate 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...

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
