China is the country of a water resources critical shortage, and water resources ownership per capita has only 2200 cubic metres, be merely the world per capita water resources 1/4, be ranked first 10 in the world, classified as one of 13 poor-waters country by United Nations.Over nearly 20 years, along with population increase, rapid economic development, urbanization process are accelerated and the physical environment variation, the shortage of water resources problem is on the rise.According to statistics, in 660 cities, the whole nation, 400 lacks of water are arranged, more than 110 serious water shortage also has more than 2,000 ten thousand people in the countryside dysdipsias in addition.A the whole nation year lack of water total amount is about 30,000,000,000 to 400 billion cubic meters, and the annual financial loss that causes because of lack of water reaches 2,000 hundred million yuan.
The area of earth surface 2/3 is awash, and wherein 97% is seawater and brackish water, and fresh water only accounts for 3%.Although seawater and sea of bitterness water reserve are abundant, they must pass through desalination could be the human use.The desalination technology that uses at present mainly contains two kinds of reverse osmosis method and distillation method, and two kinds of methods all need consume the wide variety of conventional energy, and cost is very high.Consider the problem of the in short supply day by day and energy use efficiency of world today's energy, obviously press for and seek new method for desalting seawater.
The present invention is a kind of two thermal source spray evaporation desalination technologies that utilize solar energy air heat collector and solar water heater; The warm air that solar energy air heat collector is produced sprays into evaporator room; Mix with the water smoke that sprays into from solar water heater to vaporizer; Contact with intensive hot copper pipe, make evaporation of seawater, water vapor feeds the cold fresh water that is liquefied as of condensing surface chance can supply human the use.This process sun power utilising efficiency is higher, and clean environment firendly, and save energy is beneficial to and promotes the use of, and social benefit is better.
Summary of the invention
The objective of the invention is to utilize seawater and solar energy resources abundant on the earth, designed a kind of sea water desaltination treatment unit.This installation cost is low, take up an area of little, the implementation process high-efficiency environment friendly.
The objective of the invention is to utilize following technical scheme to realize: a kind of device that adopts two thermal source spray evaporation desalination technologies, comprise cold water storage cistern 1, solar water heater 2, vaporizer 3, solar energy air heat collector 4, condensing surface 5 is characterized in that; Cold water storage cistern 1, solar water heater 2, vaporizer 3; Condensing surface 5 pipeline successively connects; Vaporizer 3 is connected with solar energy air heat collector 4 pipelines, and vaporizer 3 is gone back pipeline and connected concentrated seawater freight container 6, and condensing surface 5 is connected with airsetting separator 7, fresh water collection box 8 pipeline successively.
Vaporizer 3 also has a pipeline to connect solar water heater 2, makes single loop of forming between solar water heater 2 and the vaporizer 3.
Cooling water tank (1) and condensing surface (5) connect to form the loop through pipeline.
Be provided with a blower fan between solar energy air heat collector (4) and the vaporizer (3), the warm air that is produced in the solar energy collector (4) is blown in the vaporizer (3).
Advantage of the present invention and positively effect:
(1) adopting the two thermals source of warm air and hot sea water is the energy, improves evaporation of seawater efficient, not only save energy, and clean environment firendly.
(2) utilize blower fan to carry air in this device, cancelled traditional required vacuum pump of solar distilling seawater, can practice thrift a large amount of electric energy.
(3) vaporizer of this device design is that warm air and seawater spray into respectively, does not need the seawater solar energy collector of flowing through, and has reduced the corrosive nature of seawater to solar energy air heat collector.
(4) recycle system of cooling water tank in this device and condensing surface composition through the refrigerating unit in the cooling water tank, is that seawater circulates, and guarantees the low temperature of water coolant in the condensing surface, guarantees evaporation efficiency.
