Abstract
The invention discloses a deep-well gravity reverse osmosis seawater desalting device. A reverse osmosis seawater desalting device body is placed under a deep well with the depth being about 534 meters, and the differential pressure (the pressure of about 60 kg per square centimeter) of seawater is used for conducting reverse osmosis seawater desalting. The process that a high-pressure pump drives the seawater for reverse osmosis in a general reverse osmosis seawater desalting technology is omitted, the water pressure difference formed by the depth of the deep well is used for replacing the water pressure generated by the high-pressure pump, and the specific gravity of the seawater is about 0.89; in other words, only the seawater depth of about 534 meters is needed so that a certain object can generate the water pressure of 60 kg per square centimeter at the depth, and the pressure with the pressure difference is used for conducting reverse osmosis seawater desalting. The technology is characterized in that the deep well of 534 meters needs to be vertically tunnelled downwards through an improved shield tunneling machine so that the technology can be realized, in this way, seawater desalting cost is reduced, produced fresh water is made cheaper, and it is promising that the device can be used for agricultural production.
