Description
Technical field
The present invention relates to desalinization process field, particularly relate to a kind of efficient sea water desalting equipment.
Background technology
Water resource is basic natural resources and strategic economic resources, and sustainable utilization of water resource is to be related to economic society
The Vital Strategic Problems that can develop, in tellurian gross amount of water resources, fresh water only accounts for 2.5%, and sea water accounts for 97.5%.Seawater utilization
It is human society one of the important measures that solve water resources crisis.
In 16 end of the centurys, the mankind start to carry out preparing fresh with distillator direct evaporation sea water aboard ship, and 19 end of the centurys, along with steaming
The appearance of steamer ship, vaporizer producing distilled water is born the most therewith, to meet the supply of steamer boiler and drinking water.50 years 20th century
Occur for multi-stage flash evaporation technology.The sixties U.S. successfully prepared in the world first equipment with high desalinization, high pass penetration, can be used for sea
The asymmetric cellulose acetate reverse osmosis film of water desalination, and produced First reverse osmosis unit in the world in the seventies, with
The development of the technology such as the raising reverse osmosis membrane performance raising, prices, energy recovery efficiency, hyperfiltration becomes investment
Province, the desalinization potable water mode of low cost.The eighties in 20th century, low-temperature multiple-effect distillation emerged, light with embrane method sea water
Change technology is compared, and it is big etc. that the way of distillation has available low grade heat energy, production capacity low to raw material seawater water quality requirement, device
Advantage, low-temperature multiple-effect seawater desalination technology refers to the highest evaporating temperature of the saline desalination technology less than 70 degree, it is characterized in that by
A series of horizontal tube sprinkling falling-film evaporator is together in series, and enters through evaporation repeatedly and condensation with a certain amount of steam,
The evaporating temperature of an effect next is below an above effect, thus obtains being multiple times than the desalination process of the distilled water of quantity of steam, its stream
Cheng Wei: charging sea water is preheated in heat extraction condenser and deaerates, and is divided into two streams afterwards.One logistics is as condensed fluid
Dumping and flow back to sea, additionally one logistics becomes the feeding liquid of still-process.Feed liquid is drawn after adding dirt dispersion agent
Enter in heat-recovery section respectively imitate that temperature is minimum a group.Spray system sprays feed liquid the overhead coil being distributed in each vaporizer
On, during flowing freely the most in the form of a film along overhead coil, a part of sea water is cold owing to absorbing in vaporizer
Coagulate the latent heat of steam and vaporize.The residue feed liquid pump slightly concentrated is driven in next group of vaporizer, the operation of this group
Temperature than upper one group higher, in new group again be repeated evaporation and spray process.Remaining feed liquid is beaten the most forward, directly
To finally leaving this effect group with the form of concentrated solution in the effect group that temperature is the highest.Raw steam is input to the steaming of the highest effect of temperature
Sending out inside pipe, while condensing in pipe, pipe is outer also creates the evaporation essentially identical with condensation number.The secondary produced steams
Vapour through strong brine liquid drop separator with ensure distilled water purity after, be incorporated into again next effect heat-transfer pipe in, second
The operation temperature and pressure outline of effect is less than the first effect.This evaporation and condensation process weigh along each effect of a string vaporizer always
Multiple, often to imitate and all create a considerable amount of distilled water, the steam imitated to last is condensed by sea water coolant in heat extraction section.First
The condensed fluid of effect is collected, and a part for this distilled water returns to again steam generator, exceedes the raw quantity of steam of input
Part is flowed in the first container of a series of special container, and each container is all connected to the condensation side of next low temperature effect.This
Sample makes a part of distilled water produce flash distillation and make remaining product water cool down, and imparts heat to the main body of recuperation of heat effect simultaneously
In.So stepped flowing of product water by flash cooled step by step.Liberated heat improves the aggregate efficiency of system, cold
But distilled water is finally extracted out with water pump and is input in fluid reservoir.The product water so produced is pure water completely, and it is not
Containing any pollutant, mean salt amount is less than 20ppm.If installing two-stage mist eliminating net, product water salt content is smaller than 5ppm.Picture
Distilled water is the same, and concentrated seawater is from the first effect stepped inflow a series of strong brine flash tank, and flash cooled is to reclaim
Its heat.After supercooling, strong brine squeezes into sea through strong brine pump.Incoagulable gas is extracted out from each condensing tube,
And flow to another effect from an effect.These incoagulable gas are finally enriched with at the coldest end of heat extraction condenser, and use steam jet ejector
Or mechanical vacuum pumped.

(1) low due to operation temperature, it is to avoid or slow down corrosion and the fouling of equipment；
(2) pretreatment of charging sea water is the simplest.System hypothermia operation can simplify the preprocessing process of sea water.Sea water enters
Only need to be through screen filtration and the antisludging agent adding about 5ppm before entering low-temperature multi-effect device, being also not required to multistage flash evaporation must
Acid adding degassing process must be carried out；
(3) power consumption of system is little.Low-temperature multi-effect system is the lowest for the power consumption carrying liquid, it is possible to decrease desalination
The water producing cost of water；
(4) system operation is safe and reliable.In low-temperature multi-effect system, in happens is that pipe, steam condenses and manages outer liquid film and steam
Sending out, even if heat-transfer pipe there occurs that corrosion failure leaks, owing to vapour lateral pressure is more than side of liquid film pressure, strong brine can never flow
In product water.
The condensation of low-temperature multiple-effect distillation and the heat transfer coefficient of evaporation process improve with its operation temperature and improve, simultaneously by
When low-temperature operation, the specific volume of steam is bigger so that the volume tool of equipment is big, virtually adds the input cost of equipment, because of
This, technically need to improve as much as possible the operation temperature of low-temperature multi-effect process, make up to higher water generation ratio, and improve behaviour
Make temperature and add energy resource consumption the most to a certain extent.
To sum up, how to reduce the volume of sea water desalinating unit, reduce energy resource consumption, raising desalinization speed and efficiency,
Seem increasingly important.
