The invention belongs to field of sea water desalting technology, more particularly, it relates to a kind of that deep seafloor fresh water is defeated
It is sent to the induction system and method on land.
Background technology
Water is lifespring, is also resource for the survival of mankind, and it is the lifeblood of socio-economic development.However, I
Now the problem of be but faced with water resource critical shortage.It data show, be stored in total moisture storage capacity about 1386 × 10^ of the earth
7 billion cubic meters, wherein ocean water are 1338 × 10^7 billion cubic meters, the 96.5% of global total Water are accounted for, in remaining water
Middle surface water accounts for 1.78%, and underground water accounts for 1.69%, the fresh water that the mankind mainly utilize about 35 × 10^7 billion cubic meters, global total
2.53% is only accounted in moisture storage capacity.Therefore, make full use of the problem of desalinization is to alleviate shortage of water resources very urgent.
At present, desalination technology mainly uses the way of distillation and hyperfiltration, and some blue waters are to utilize height
The pressure of nature water column is pressed to carry out desalinization.This technology, which can make full use of, can provide the new energy utilized, can not only save
Electricity consumption and pretreatment expense, but also the expense of film replacing can be saved, water producing cost is relatively low.However, light after desalinating in seabed
Water transport but needs more energy to land.Traditional way is aspirated using pump, and this way is fairly simple, but
That can but pay more costs, so as to increase cost, and equipment loss also than more serious.
The content of the invention
The purpose of the present invention is exactly to solve the problem of above prior art is present, and provides a kind of deep seafloor fresh water for this
Induction system and carrying method.
The technical scheme is that：
A kind of deep seafloor fresh water induction system, including it is arranged at the water tank in seabed, the both sides difference of the water tank upper end

The phase change chamber that distal process thereon goes out the water tank is inside provided with, the side of the phase change chamber upper end is provided with fresh water by check valve and gone out
The mouth of a river, the opposite side of the phase change chamber upper end is provided with the fresh water water inlet of connection fresh water tanks by check valve；Described phase
Become interior and be provided with the piston for being divided into upper and lower two chambers, the bottom chamber of the phase change chamber is filled with CO2With ethane composition
Mixed working fluid.
A kind of method that use system above conveys deep seafloor fresh water, including below scheme：
(1) sea intake valve is opened, Mare Frigoris water is injected into water tank, makes CO2Shunk simultaneously with the mixed working fluid that ethane is constituted
Band piston declines, and the fresh water in fresh water tanks enters the upper chamber of phase change chamber by fresh water water inlet；
(2) concentrated seawater inlet valve is opened, the concentrated seawater after desalination is passed through into described water tank, makes the Mare Frigoris water in water tank
Discharged by outlet valve, make CO2Working medium expanded by heating simultaneously rises with piston, the fresh water of phase change chamber upper chamber is gone out by fresh water
The mouth of a river is transported to bank land；
(3) alternating (1), the process step of (2), pass through the phase change chamber bottom chamber CO2The mixing work constituted with ethane
Contraction, the expansion of matter, drive described piston to decline, rise, so that the fresh water in the phase change chamber upper chamber is constantly defeated
It is sent to bank land.
Compared with prior art, its advantage is the present invention：
(1) pressure of application high-pressure natural water column carries out desalinization, and makes full use of concentrated seawater and seabed after desalination cold
The temperature difference of seawater carries out fresh water transport, reduces the acting consumption of fresh water transport；
(2) temperature difference and CO of concentrated seawater and Mare Frigoris water are taken full advantage of2Working medium specific volume in contraction, expansion process becomes
The characteristics of changing larger, making the carrying method of deep seafloor fresh water tends to be simple, realizes low cost, high efficiency conveying deep seafloor
The purpose of fresh water；
(3) from raw material sources are wide, cheap, environment friendly and pollution-free, can reduce the CO of the advantages such as sealing cost2
Mixed as working medium, and by it with ethane, to improve operating efficiency；
(4) fresh water conveying is carried out by contraction, the expansion of the temperature difference and piston of concentrated seawater and seabed Mare Frigoris water, than it
Traditional pumping absorbing method, both reduces cost, turn avoid serious equipment loss, with good practicality.
