For realizing the seawater underground factory desalination system of said purpose, be characterized in, comprise geothermal well, underground factory; Reverse osmosis membrane assembly, fresh-water tank, fresh water lift pump, seawater dope pipe; Dope is discharged potential difference relay pump, external or built-in fluid column vertical tube, man-machine passage, ventilator trunk and control gate; Reverse osmosis membrane assembly and fresh-water tank are installed in underground factory, man-machine channel connection ground and underground factory, ventilator trunk is communicated with ground and underground factory; The bottom diffusion that clean seawater gets into geothermal well absorbs the underground heat that the underground heat borehole wall transmits, and gets into external placed type or built-in fluid column vertical tube through pipeline and control gate again; The water outlet of clean warm seawater in external placed type or built-in fluid column vertical tube in external placed type or built-in fluid column vertical tube bottom flows out the reverse osmosis membrane assembly that gets in the underground factory desalinates; Fresh water after the desalination flows into fresh-water tank; See ground by the fresh water lift pump off via the fresh water pipe that is arranged in external placed type or the built-in fluid column vertical tube again; The dope of output is then via discharge tube after the sea water desaltination; Discharge tube is positioned at external placed type or built-in fluid column vertical tube; And constitute communicating vessels with external placed type or built-in fluid column vertical tube, and the dope relief outlet water level of this discharge tube is lower than the gauging line of external placed type or built-in fluid column vertical tube, and dope is discharged the potential difference relay pump dope of discharge tube is discharged.
Described seawater underground factory desalination system, its further characteristics are also to comprise the warmed-up seawater of waste heat of plant or 15 ° of pipelines that directly join external placed type or built-in fluid column vertical tube to the clean warm seawater between the equator of latitude.
Described seawater underground factory desalination system, its further characteristics are that the degree of depth of geothermal well is greater than 600 meters.
Described seawater underground factory desalination system, its further characteristics are that underground factory is located at underground 600 meters.
Described seawater underground factory desalination system, its further characteristics are that ventilator trunk is arranged in the man-machine passage.
The utility model one is underground factory still to be located at about 600 meters (satisfy 60kgf/cm
2Water colunm pressure just can); And the endothermic tube setting of the seawater of will heating and number of patent application " 201110065188.4 " are inequality, but replace " constituting the underground heat endothermic tube of one in the underground natural circulation heat absorption purification system with the fluid column passage " with darker geothermal well.Geotemperature is higher like this, and heat is bigger, is more suitable for 32 ° of seawater heat absorptions with the water-deficient area, upper frigid zone of northern latitude and heats up, and further helps the product fresh water amount of sea water desaltination.
Following table is depths, a ground temperature conditions:
| 500 meters | 600 meters | 1000 meters | 2000 meters | 3000 meters | 4000 meters |
| 13～25℃ | 18～37.5 |
23～50℃ | 40～100℃ | 70～150℃ | 80～200℃ |
Therefore, the utility model can be at northern latitude special cold district more than 32 °, when no waste heat of plant can supply, carries out reverse osmosis seawater desalting, so not only can improve product fresh water amount and can also save more electric power
The 2nd, there are warmed-up seawater of waste heat of plant or latitude directly to get into underground factory to the clean warm seawater between the equator through the fluid column vertical tube for 15 ° and carry out desalination by reverse osmosis, further save the power consumption of sea water desaltination primary device.
