Abstract

The invention discloses an active solar energy and wind energy coupling seawater desalination plant. A solar cell panel and a wind driven generator are connected with a storage battery through a charging controller; the storage battery drives a vacuum pump to work; an original seawater inlet pipe is connected to a solar heat collector through a heat exchanger and enters into a seawater evaporator, which is equipped with a fresh water outlet and a condensed seawater outlet; the fresh water outlet is connected with a fresh water outlet pipe passing through a heat exchanger; and the condensed seawater outlet is connected with a condensed seawater outlet pipe passing through a heat exchanger. The invention can collect electric energy generated by solar energy and wind energy in the storage battery and prolong a vacuum pump working time in breezeless and dark weather; besides condensed seawater, steam and fresh water mixture with large enthalpy respectively pass heat of their own to the original seawater through the heat exchanger, so as to fully utilize waste heat and realize reasonable energy utilization.

Description

technical field [0001] The invention relates to a desalination technology of seawater, in particular to a device for desalination of seawater by utilizing solar energy and wind energy. Background technique [0002] my country is a country lacking in water resources. The per capita water consumption ranks only 108th in the world, which is equivalent to 1 / 4 of the world's average level. Water-deficient cities account for 2 / 3 of the cities in the country. Therefore, water resources have become a factor that affects my country's sustainable development. one of the key factors. Under the circumstances that underground water intake and inter-regional water transfer are subject to more and more conditions, using seawater desalination to obtain new water sources is an important strategic way to solve the shortage of fresh water in our country. [0003] Seawater desalination is the technology and process of using seawater desalination to produce fresh water. The mature technologies f...
