System device for preparation of fresh water and salt by all-weather seawater self-pumping power generation for heating and condensation

Abstract

The invention discloses a system device for preparation of fresh water and salt by all-weather seawater self-pumping power generation for heating and condensation; according to the system device, a dual-use waterwheel pulse pump can improve the water level to more than one hundred meters by use of single set or multiple sets of flowing water-pushed series-connected pumps, the dual-use waterwheel pulse pump is actually an unpowered water pump for providing water used for farmland of a no-power region, or for a shaft-type hydroelectric generator for all-weather power generation and for all-weather seawater desalting for preparation of the fresh water and the salt; When seawater flows past a gravity evaporation condensation vacuum pump, the seawater can be instantaneously evaporated or condensed, salt particles in seawater desalination steam can be collected by self-gravity descending, high temperature steam and a low temperature vapor phase collide to condense into the fresh water to flow out, and the fresh water flows past a connected water purifier and an ozone sterilizer to produce safe drinking water, the seawater can be instantaneously evaporated or condensed into the fresh water without any electric energy, seawater desalination equipment is simple in manufacturing, low in cost, high in seawater desalination efficiency and low in seawater desalination cost, can be widely popularized and applied, is a most effective and green economic approach and strategic guideline for thorough seawater desalination of water resources of the whole world, and for attracting foreign capital investment and solving domestic water resources.

Description

[0001] Technical field: water resources; seawater desalination. Background technique: [0002] The fresh water content on the earth only accounts for 2.53% of the total global water volume, 68.7% of which belong to solid glaciers, which are distributed in difficult-to-use alpine and polar regions, and part of the fresh water is buried deep underground and difficult to extract. [0003] At present, the fresh water that humans can directly use comes from groundwater, lake fresh water and river bed water. With the deteriorating environment, these fresh water resources are becoming more and more scarce, especially in desert and island areas. [0004] There are 70% ocean areas on the earth's surface, and more people lack fresh water on islands and coastal areas. [0005] However, human survival and social development require sufficient freshwater resources. At present, only the huge and inexhaustible seawater possessed by the natural ecology of the earth can be exploited to produce...
