Problems solved by technology
The use of ocean energy, such as tidal energy or wave energy, can raise the height of seawater, and then use the pressure difference of seawater to generate electricity and work, etc., but because the pressure difference is not large, its efficiency is often relatively low, and it is not easy to use

Embodiment 1
[0018] Such as figure 1 As shown, the seawater well water surface 2 is higher than the ground 1 by a certain height, such as about 8 meters. The seawater outlet 48 is flush with the ground 1, and the depth of the seawater well 3 is about 38 meters. Using ocean energy, such as tidal energy and wave energy, the seawater in the sea 50 is sent into the seawater well 3 through the seawater ascending channel 49 and filled. After the system was in normal operation, the seawater discharge pipe 47 was also filled with seawater. The device of the present invention is fixedly installed at the bottom of the equipment well 51. The device introduces seawater from the seawater inlet 4 at the bottom of the seawater well 3. Part of the introduced seawater is used as raw seawater for making fresh water, and the other part is used to drive the booster equipment. And drainage equipment, and the working seawater in the device is discharged into the seawater discharge pipe 47 through the seawater...

The invention discloses a reverse osmosis seawater desalting method and a reverse osmosis seawater desalting device by utilizing ocean energy. A well is dug on the seaside, and is divided into two sides, one side serves as a seawater well, and the other side serves as an equipment well; seawater is delivered into the seawater well by utilizing the ocean energy and the water level of the seawater well is higher than the sea level; and devices are fixedly arranged on the bottom of the equipment well, and comprise a seawater inlet and outlet system, a conveyor system for the seawater to be boosted, a booster device, a seawater drainage device, a reverse osmosis membrane module, a fresh water lifting system and a concentrated seawater drainage system. The seawater on the bottom of the seawater well is introduced into the device through the seawater inlet system of the device, and drives the booster device and the drainage device; the booster device produces high pressure seawater; the high pressure seawater generates fresh water and residual concentrated seawater through the reverse osmosis membrane module; the fresh water is lifted to the ground by a common pump; the concentrated seawater is discharged out of the ground through excess pressure; and the drainage device is mainly used for discharging the seawater in the booster device and the drainage device per se so as to maintain the continuous operation of the device.
Description
technical field [0001] The invention relates to a reverse osmosis seawater desalination method and device which utilizes the pressure difference between the high water level formed by ocean energy and the low water level at the bottom of a well to pressurize. Background technique [0002] There are many methods that can be used for seawater desalination, but currently the large-scale seawater desalination methods that can be applied to commercial use mainly include distillation and reverse osmosis, among which reverse osmosis is the most energy-efficient of all seawater desalination methods. Nevertheless, the cost of fresh water produced by reverse osmosis seawater desalination is still relatively high. One of the main reasons is that most of the current reverse osmosis seawater desalination uses high-pressure pumps to produce high-pressure seawater, which consumes a lot of electricity. Therefore, some researchers are studying reverse osmosis seawater desalination methods th...
