Description
Technical field
A kind of seawater desalination system is the utility model is related to, specifically.It is a kind of deep-sea suspended sea of no breather pipe
Water desalination system, belong to Naval Architecture and Ocean Engineering technical field.
Background technology
Counter-infiltration membrane type desalinization is a kind of currently used desalinization mode, has been largely used to land and ship
Oceangoing ship.Reverse osmosis membrane requires the pressure differential for reaching 5MPa even more highs on film, and hydrone could be allowed to produce fresh water through reverse osmosis membrane.
Therefore on the land or on the vessel, it is necessary to the supply-water pump for setting pressure to exceed 5MPa, seawater is provided for reverse osmosis membrane, and flow through reverse osmosis
In the seawater of permeable membrane, only about 30% turns into fresh water, and others flow away as strong brine, makes high-pressure water supply pump power consumption larger.
In order to save the energy expenditure of desalinization, people come up with a variety of methods, including light using deep sea water
Change method, i.e., be arranged in deep-sea by sea water desalinating unit, using the hydrostatic pressure of seawater, produces the High Pressure Difference inside and outside permeable membrane,
So as to produce fresh water, then with water pump will fresh water transportation by lighter to more than sea level, thus only need to expend the energy of conveying fresh water, and
Most seawater without being pumped again.In the deep-sea of 500-700 rice or so, seawater is compared with the seawater on sea level, and water quality is more
Add cleaning, marine growth is difficult to survive, and water temperature is more constant, be adapted to directly to allow seawater into reverse osmosis membrane make it is light.
In current existing desalinating sea water in deep sea method, problems with is primarily present：
1st, manufacture fresh water enters water tank, and its inner air, which is extruded, to be needed to discharge；, again need to be to water storage when fresh water is sucked
Supplement air in tank, breather pipe is mainly drawn to more than the water surface using deep-sea desalting plant at present.Breather pipe up to 500 meters or
More, it is atmospheric pressure in pipe, it is high hydraulic pressure that pipe is outer, and the pressure difference born is very big.Pipe connects deep-sea desalting plant and the water surface
Platform, mutually motion easily cause breather pipe bending, deformation etc. so that and pipe technical requirements are high, difficulty is big, system complex, and
And the potential safety hazard that whole system fails after leakage being present or blocking；
2nd, equipment is numerous on the desalting plant of deep-sea, and center of gravity, centre of buoyancy are difficult to determine, prestowage is difficult.When water tank is slack tank,
Centre of buoyancy is on the lower side, easily causes inclination so that the system failure；
3rd, in deep sea waters, without wave, and may also there is no ocean current, wave energy can not be used to provide energy for device
Source promotes current flowing, when strong brine flows not smooth in reverse osmosis membrane, can cause to make light efficiency decline.

When fresh water flows downwardly to water tank by gravity, it is upward that it extrudes air automatically, because air is compressible, including air
Air pressure including tank, desalinization component etc. rises, and it is limited that sufficiently large air tank, which ensures that air pressure rises,
's.Because desalinization module is placed at least 500 meters of the depth of water, the operation principle of desalinization is inside and outside reverse osmosis membrane
Produce about 5MPa pressure difference, you can produce fresh water.Therefore when internal because air compression build-up of pressure rises, reverse osmosis membrane it is interior
External differential reduces, and due to the presence of air tank, internal pressure rises to more 0.1MPa, and inside and outside differential pressure is had little to no effect,
Therefore the breather pipe towards more than the water surface need not specially be set；Internal system also need to only set a fresh water collecting pipe, simplify system,
Add reliability.
2) top of underwater deep-sea suspended desalinization module sets air tank, and lower section sets water tank.So
Upper, center of gravity is under, it can be ensured that the also marine holding correct body position of module, prevents from toppling, improves device for the centre of buoyancy of module
Reliability.
