Abstract
The invention relates to a seawater desalting method, belonging to the field of seawater desalinization. The method comprises a standing procedure, a filtering procedure, an evaporating procedure and a condensing procedure, wherein sweater subjected to the standing procedure is subjected to the filtering procedure; the filtering procedure is used for filtering solid suspension particles or impurities in seawater and feeding into the evaporator procedure; in the evaporator procedure, an enclosed evaporating chamber to which electric heating films are attached to the four walls and the bottom is used; evaporated seawater vapor is fed into a vapor compressor for compressing; compressed vapor is condensed into water drops which fall off in a condensing chamber, and the water drops are conveyed into a water storage tank through a conveying pipe; and all energy used in the entire procedure process is supplied by energy storing equipment. The method has simple and convenient procedures, relatively low energy consumption, low cost and a good desalting effect, is easy to popularize, and is particularly suitable for supplying small amount of fresh water to small households on coastal household users, small sea islands, and the like.
Description
Technical field
The present invention relates to a kind of sea water desalinization desalination method, belong to the sea water desaltination field.
Background technology
Along with the development of science society and the continuous growth of population; The crisis of resource problem has become the very urgent matter of utmost importance that needs to be resolved hurrily; Water resources is human Source of life; Human Activities all be unable to do without water resources, how to realize that the recycle of water resources and sustainable development are that each scientific and technical personnel research and develop one of important topic of test.People are in the recycle of research water resources, and anti-harnessing the river when polluting also is converted into fresh water at 97% the seawater how research will take up an area of Total Water on the ball, further satisfies the demand of human development.
Utilizing sea water desalinization to produce fresh water, is the increment technique of increasing income that realizes the water resources utilization, can increase the fresh water total amount, and not receive space-time and weather effect, and water quality is good, price is gradually reasonable, can ensure stable water supplies such as coastal resident's tap water and Industrial Boiler moisturizing.
At present; Used method for desalting seawater has several different methods such as seawater freezing method, electroosmose process, distillation method, reverse osmosis method, but existing desalination technology exists equipment various, complex procedures; Cost drops into higher; Improper small user, like coastal resident, use in order to a small amount of fresh water supply on little island etc.
Summary of the invention
Defective in view of prior art exists the objective of the invention is to provide a kind of sea water desalinization desalination method, and this method has that equipment cost is cheap, operation is simple, low power consumption and other advantages.
For realizing above-mentioned purpose, the technical solution that the present invention adopted is:
The sea water desalinization desalination method comprises and leaves standstill operation, filtration operation, evaporization process and four operations of condensation operation that it is characterized in that: the described operation that leaves standstill left standstill in the pond 2-5 hours for seawater is extracted to leave standstill, and leaving standstill the pond is cement pit or water tank; Seawater through leaving standstill carries out the filtration treatment operation, and described filtration operation selects for use two ends to have the hydraulic pipe of filtering net, and the feed-water end of hydraulic pipe is provided with the removable filter coarse net; Seawater is carried out coarse filtration; Bigger solid suspended particle or impurity in the filtering seawater, the water side of hydraulic pipe is provided with the removable filter fine-structure mesh, and seawater is further filtered; Less solid suspended particle or impurity in the filtering seawater, seawater to be evaporated after filtering gets into next process; Described evaporization process is the enclosed evaporator room that Electric radiant Heating Film is posted in wall and bottom; The upper end of evaporator room is provided with a withdrawal device; Evaporate the seawater steam that in order to extraction; Seawater steam is sent to and carries out processed compressed in the vapour compressor, and the steam after the processing is admitted to and carries out the condensation operation in the condensing chamber; Vapor condenses becomes water droplet to fall in condensing chamber, condenses into current, is delivered in the water tank in order to using by transfer lime; The energy that in whole operation process, uses is all provided by energy storage device; Described energy storage device comprises solar panel; Sun power/energy converter and store battery are formed, and solar panel is harvest energy under daylight, converts thereof into electric energy through sun power/energy converter; Be stored in the store battery, with thinking that desalting process provides energy.
Adopt such scheme to have the following advantages with comparing with class methods: equipment required for the present invention is simple, and operation is simple and direct, and energy consumption is lower; With low cost, the desalination effect is preferable, is easy to popularize; Be particularly suitable for coastal resident, use in order to the small user of a small amount of fresh water supply on little island etc.
