Description
Technical field
The utility model relates to water treatment field, and a kind of embrane method sea water desalting equipment is provided especially.
Background technology
China is a country that drought and water shortage is serious.The Freshwater resources total amount is 28000 billion cubic meters, account for 6% of water globe resource, be only second to Brazil, Russia and Canadian, occupy the 4th in the world, but have only 2200 cubic metres per capita, only be world average level 1/4, the U.S. 1/5, rank 121 in the world, be the whole world one of 13 countries that water resources is the poorest per capita.After deducting the flood river rising in Ningxia and flowing into central Shaanxi stream that is difficult to utilize and being dispersed in the groundwater resource of remote districts, the available Freshwater resources amount of reality of China then still less, only be about 11000 billion cubic meters, can utilize water resources quantity to be about 900 cubic metres per capita, and its distributed pole be unbalanced.To 20 end of the centurys, in more than 600 city, the whole nation, there is the insufficient water problem in existing more than 400 city, and wherein more serious lack of water city reaches 110, and National urban lack of water total amount is 60 billion cubic meters.
China's Urban water supply is based on surface water or underground water, and perhaps two kinds of water sources mix and use, groundwater table decreasing is caused because of the underground water overexploitation in some city, and the city that has has formed the big funnel of hundreds of square kilometre, makes the tens of kilometers of inwelling.Because the discharging wantonly of trade effluent causes surface water, underground water more than 80% contaminated.And the trend that increases the weight of is year by year arranged.The water that is on the rise pollutes the functions of use that has not only reduced water body, the contradiction of further having aggravated shortage of water resources.
Brainstrust warning: " China will can not find drinkable water resources after 20 years ".The U.S. influential think-tank among the people---claim in the portion report that World Watch Institute delivers: " because Chinese city area and industrial area increase rapidly water demand, China will be absorbed in water shortage status for a long time." Chinese the Yellow River cutout every year in more than 10 year in the past, wherein cutout in 1997 is 226 days.Flow through China some geographic Huaihe River of population dense set also stopped 90 days last year.According to the photo that satellite is taken, hundreds of lakes are dry, and some endemic rivers are also disappearing.
Face so serious water crisis, we have to find a new Water resources development approach, adopt reverse osmosis technology to carry out sea water desaltination, as the increment technique of increasing income of water resources, have become the important channel that solves the water globe crisis of resource." want fresh water to the ocean " and formed industry in the ascendant, several main light methods of seawater have the MSF(multistage flash evaporation), the ME(multi-effect distilling), the RO(reverse osmosis).
Wherein, sea water desaltination is one of reverse osmosis technology main application fields.Compare with traditional distillation method, the variation of phase does not take place in the reverse osmosis seawater desalting process.According to calculation of thermodynamics, normal temperature only is about 0.7 kWh/m3 with the lowest energy consumption of desalination by reverse osmosis process seawater down.So theoretically, it is the most energy-conservation method for desalting seawater.
Yet also there are some problems in the embrane method sea water desaltination, and wherein the required osmotic pressure height that overcomes of high-pressure pump most importantly so just derives another problem, and promptly the energy of high-pressure thick water utilizes again.
Therefore, we are badly in need of seeking a kind of novel sea water desalting equipment, utilize problem with the energy that solves high-pressure thick water.
The utility model content
The purpose of this utility model is to provide a kind of embrane method sea water desalting equipment, utilizes problem with the energy that solves high-pressure thick water.
The utility model provides a kind of embrane method sea water desalting equipment, it is characterized in that: described equipment is made up of security personnel's strainer 1, energy recycle device 2, topping-up pump 3, high-pressure pump 4 and the filtration unit 5 that has a sea water desaltination RO film;
---wherein, described security personnel's strainer 1 is provided with water inlet 11 and two water outlets, and one of them water outlet is connected in order successively with energy recycle device 2, topping-up pump 3, filtration unit 5; Another water outlet is connected in order successively with high-pressure pump 4, filtration unit 5;
---filtration unit 5 is connected with energy recycle device 2, and filtration unit 5 is provided with water outlet 51, and energy recycle device 2 is provided with dense water out 21.
The principle of work of the embrane method sea water desalting equipment that the utility model provides, specific as follows: seawater enters security personnel's strainer by water inlet, seawater after the filtration is divided into two tributaries, and a tributary is carried out feeding the filtration unit that has sea water desaltination RO film again after high pressure pressurizes via high-pressure pump and filtered; And energy recycle device is passed through in another tributary, carry out supercharging through topping-up pump then, feeding the filtration unit that has sea water desaltination RO film after meeting the requirements of pressure values filters, the final fresh water that obtains that filters is directly discharged by water outlet, and being back to again in the energy recycle device of the high-pressure thick water after handling, energy recycle device makes it discharge from dense water out with after its energy recovery.
In the utility model, setting by energy recycle device and topping-up pump, effectively utilized the energy of high-pressure thick water, the energy that is reclaimed can be directly used in the pressure that improves the seawater feedwater, thereby part has replaced the effect of high-pressure pump, thereby reduce the investment of high-pressure pump, and then reduce the energy consumption of embrane method seawater desalination system, save energy.
