[0021] The present application provides a deep-sea floating platform 200 desalination system 100.

[0022] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the deep-sea floating platform 200 includes a hull 201, a deck 202 arranged on the top of the hull 201, and a cabin 203 arranged on the top of the deck 202, the cabin 203 includes an inner cabin wall and an outer cabin wall; the desalination system 100 includes a collection mechanism 1, a sedimentation cabin 2, a water quality detection device 3, two purification devices 4 and two storage cabins 5; the collection mechanism 1 includes a first collection groove 11, a second collection groove 12 and a third collection groove 13, the first collection groove 11 is arranged at the bottom of the outer cabin wall for collecting rainwater on the outer cabin wall, the second collection groove 12 is arranged on the deck 202 for collecting rainwater on the deck 202, and the third collection groove 13 is arranged at the bottom of the inner cabin wall for collecting condensed water on the inner cabin wall; the sedimentation cabin 2 is arranged in the hull 201, the sedimentation cabin 2 includes two sedimentation zones 21, the first collection groove 11 and the second collection groove 12 are communicated with one of the sedimentation zones 21, and the third collection groove 13 is communicated with the other sedimentation zone 21; the condensed water and the rainwater can enter the corresponding sedimentation zone 21 to be deposited to obtain collected water; the water quality detection device 3 is arranged in the hull 201, the water quality detection device 3 includes a detection cabin 31 and a first detector 32, the two sedimentation zones 21 are communicated with the detection cabin 31, and the collected water can enter the detection cabin 31 and be detected by the first detector 32; the two purification devices 4 are arranged in the hull 201, and the two purification devices 4 are communicated with the detection cabin 31, the detected collected water is selectively introduced into the purification device 4 to be purified to obtain fresh water; the two storage cabins 5 are arranged in the hull 201, and the two storage cabins 5 are respectively communicated with the two purification devices 4. The desalination system 100 of the deep-sea floating platform 200 of the present application can collect rainwater on the outer bulkhead by using the first collecting groove 11, collect rainwater on the deck 202 by using the second collecting groove 12, and collect condensed water on the inner bulkhead by using the third collecting groove 13. It can be understood that the temperature in the deep-sea area is low, the humidity of the marine environment is relatively large, the rainfall is relatively frequent, and there is a large temperature difference between the inside and outside of the cabin 203. The indoor temperature is high and it is easy to form considerable condensed water on the inner bulkhead. Collecting the condensed water also helps to reduce the humidity in the cabin. The condensed water is an automatically formed freshwater resource in the environment, and the rainwater is also a low-salinity and low-impurity freshwater resource compared with seawater. The condensed water and the rainwater are collected in two sedimentation zones 21 of the sedimentation cabin 2 respectively for sedimentation treatment. Most of the particulate impurities in the condensed water and the rainwater are removed by sedimentation. The impurities in the condensed water are relatively small and can be sedimented in a short time. The impurities in the rainwater are relatively large and need to be sedimented for a long time. The two are separated for sedimentation, which improves the overall sedimentation efficiency. The collected water after sedimentation is sent to the detection cabin 31. At this time, the detection cabin 31 is a freshwater with less particulate impurities and can be used for daily use, such as washing clothes. Then, the water quality of the collected water is detected. According to the water quality detection result, the collected water is selectively sent to any purification device 4 for purification to ensure that the purified freshwater meets the expected requirements. The two purification devices 4 are reasonably used to purify the collected water with different water qualities, which reduces the cost required for long-term freshwater preparation. Moreover, heating devices are not needed for distillation treatment, which further reduces the cost required for freshwater preparation.

[0023] It can be understood that there are many cabin rooms 203 on the deck 202. The bottom of the inner bulkhead corresponding to each cabin room 203 is provided with a third collecting groove 13, so that considerable condensed water resources can be collected. The outer bulkhead includes a cabin side wall and a cabin top wall. The bottom of each cabin side wall is provided with a first collecting groove 11, and the cabin top is also provided with a first collecting groove 11. There are a plurality of second collecting grooves 12 on the upper position of the deck 202. In this way, the amount of condensed water and rainwater collected is increased.

[0024] Further, the desalination system 100 further comprises a control device, and the first detection instrument 32 is electrically connected with the control device. It can be understood that the water quality detected by the first detection instrument 32 is uploaded to the control device. The control device makes the collected water enter different purification devices according to the water quality.

[0025] In an embodiment, an air conditioning unit 204 is further arranged on the deck 202. The collecting mechanism 1 further comprises a fourth collecting groove 14 arranged below the air conditioning unit 204. The fourth collecting groove 14 is used to collect condensed water generated when the air conditioning unit 204 is running. The third collecting groove 13 and the fourth collecting groove 14 are both in communication with the same sedimentation zone 21. The condensed water collected by the third collecting groove 13 can enter the corresponding sedimentation zone 21 for sedimentation to obtain collected water.

[0026] It can be understood that the internal heat exchanger of the air conditioning unit 204 will produce a large amount of condensate water during operation due to air cooling. This part of water is essentially the condensate water of water vapor in the air, and the water quality is pure and contains very low salt content, which belongs to high-quality potential fresh water resources. By setting the fourth collecting tank 14, the originally discarded air conditioning condensate water is collected, the utilization rate of fresh water resources on the deep sea floating platform 200 is improved, and the total amount of fresh water obtained is significantly improved. And the air conditioning condensate water and the internal cabin wall condensate water are both low-temperature condensate water, and the impurities are mainly trace dust or microorganisms, and the water quality is better than rainwater, and the pollution load is low, so they can be used in the same sedimentation area 21 for preliminary settlement treatment, and the layout of the system is simplified.

[0027] In an embodiment, the first collecting tank 11 and the second collecting tank 12 are respectively communicated with the corresponding sedimentation area 21 through two first pipes, and the third collecting tank 13 and the fourth collecting tank 14 are respectively communicated with the corresponding sedimentation area 21 through two second pipes; each first pipe and each second pipe is provided with a first valve 15.

For example: when the deck 202 is being cleaned or producing sewage during operation, the first valve 15 of the second collecting tank 12 can be temporarily closed to prevent impurities from mixing in; when the air conditioning unit 204 is not running or is being maintained, the first valve 15 of the fourth collecting tank 14 can be closed to prevent too many impurities from entering the corresponding sedimentation area 21; when the sedimentation area 21 is full, the first valve 15 can be closed to prevent overflow.

[0029] It should be noted that the first valve 15 can be an electromagnetic valve in the prior art, and each electromagnetic valve is electrically connected with each control device to control the opening and closing of each electromagnetic valve. In other embodiments, the electromagnetic valve can also be an on-off valve or a flow valve.

[0033] It can be understood that the collected water in the detection cabin 31 can enter the first branch pipe 91 or the second branch pipe 93 through the main pipe 81, and by providing the second valves on the first branch pipe 91 and the second branch pipe 93, and by controlling the opening and closing of the two second valves, the collected water can be prevented from entering two different purification devices 4 at the same time, so as to realize flexible delivery of the collected water and ensure the operation reliability of the desalination system 100.

[0034] It should be noted that the second valves can also be electromagnetic valves in the prior art, and each second valve is electrically connected with a control terminal to control the opening and closing of each second valve through the control terminal.

[0035] In an embodiment, the two purification devices 4 are a first purification device 4 and a second purification device 4 respectively; the first purification device 4 comprises an ultraviolet disinfection cabin 41 and a second filter 42 communicated in sequence, a water inlet of the ultraviolet disinfection cabin 41 being communicated with a water outlet end of the first branch pipe 91, a water outlet of the ultraviolet disinfection cabin 41 and a water inlet end of the second filter 42 being communicated, and a water outlet end of the second filter 42 and a water inlet of a corresponding storage cabin 5 being communicated; and the second purification device 4 comprises a pressure pump 43 and a reverse osmosis membrane filter 44 communicated in sequence, a water inlet end of the pressure pump 43 being communicated with a water outlet end of the second branch pipe 93, a water outlet end of the pressure pump 43 and a water inlet end of the reverse osmosis membrane filter 44 being communicated, and a water outlet end of the reverse osmosis membrane filter 44 and a water inlet of a corresponding storage cabin 5 being communicated.

[0036] It can be understood that the purification processes of the first purification device 4 and the second purification device 4 are different, wherein the first purification device 4 mainly adopts the ultraviolet disinfection 41 cabin and the second filter 42, which are mainly used for ultraviolet sterilization and filtration of the collected water, mainly removing microorganisms such as bacteria and suspended particulate matters, etc., so that the fresh water is more pure, and mainly suitable for low salinity collected water, such as collected water obtained after condensate water precipitation; and the second purification device mainly adopts the pressure pump 43 and the reverse osmosis membrane filter 44, the reverse osmosis membrane filter 44 is used to treat collected water with higher salinity, such as collected water obtained after rainwater precipitation, the pressure pump 43 is mainly used to provide appropriate pressure for the reverse osmosis membrane filter 44, and the reverse osmosis membrane can efficiently remove dissolved salts, heavy metals, organic matter, micro-pollutants, etc. in the collected water; Specifically, according to the water quality detection result, the collected water is sent into the first purification device 4 or the second purification device 4, the first purification device 4 and the second purification device 4 are used according to the demand, the collected water with good water quality is purified through the first purification device 4, and the collected water with poor water quality is purified through the second purification device 4, which not only ensures the purification effect, but also reduces the cost of fresh water preparation.

[0037] It should be noted that the fresh water is obtained after the second filter 42 filtration and the reverse osmosis membrane filter 44 filtration; the second filter 42 can adopt a quartz sand filter, a security filter, an ultrafiltration membrane filter or an activated carbon adsorption filter in the prior art.

[0038] In yet another embodiment, the two purification devices 4 are completely the same, and are the first purification device or the second purification device 4 described above.

It can be understood that the fresh water filtered by the reverse osmosis filter is collected by setting the water tank 46, and the second detector 45 is set to detect the fresh water in the water tank 46, so as to determine whether the reverse osmosis membrane filter 44 effectively filters the collected water or whether the reverse osmosis membrane filter 44 is damaged and fails, so as to timely detect and repair, improve the safety and reliability of fresh water output, and prevent unqualified fresh water from entering the storage cabin 5.

[0041] In yet another embodiment, the water outlet end of the second filter 42 is also communicated with the water inlet of the water tank 46, and the fresh water obtained after the first purification device 4 is developed is also detected by the second detector 45, so as to ensure that the fresh water obtained by the purification of the first purification device 4 is qualified.
