In addition to the wind power sector, the use of seawater cooling technology for cooling in the shipbuilding and power plant sectors is also becoming increasingly common.

[0003] When using seawater for cooling, it must be filtered to prevent clogging of the seawater heat exchange system. However, filtered seawater can still contain marine organisms such as microorganisms and fish eggs, which can cause serious contamination of the heat exchange system pipes. Therefore, disinfection of these marine organisms is necessary. Summary of the Invention

DETAILED DESCRIPTION

[0014] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art. The terms used in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0016] The use of seawater cooling technology, replacing air cooling, is becoming increasingly common in wind power, shipbuilding, power plants, and other sectors. This involves exchanging heat between hot coolant and seawater in a seawater heat exchange system. The coolant, after cooling, is returned to the heat source to continue cooling it, while the heated seawater is discharged directly into the sea.

[0017] When using seawater for cooling, it must be filtered to prevent it from clogging the seawater heat exchange system. However, filtered seawater can still contain marine organisms such as microorganisms and fish eggs. If these enter the seawater heat exchange system, they can cause serious contamination of the pipes, affecting the power generation efficiency of wind turbines, for example. Therefore, marine organisms must be eliminated.

[0018] The present disclosure provides a marine organism suppression system that can utilize waste heat from a seawater heat exchange system to disinfect organisms in seawater used in the seawater heat exchange system.

[0019] Hereinafter, a marine life suppression system according to an embodiment of the present disclosure will be described with reference to FIG. 1 to FIG. 3 .

[0020] FIG1 illustrates a marine growth suppression system according to a first embodiment of the present disclosure. As shown in FIG1 , the marine growth suppression system according to the present disclosure may include: a seawater heat exchange system 10, in which seawater and a hot coolant are exchanged; a seawater holding tank 20 for holding seawater; a hot water bypass 30 connecting a seawater outlet 12 of the seawater heat exchange system 10 and the seawater holding tank 20; a main seawater channel 40 connecting the seawater holding tank 20 and the seawater inlet of the seawater heat exchange system 10; and a water pump 50 for supplying seawater to the seawater holding tank 20 and supplying seawater from the seawater holding tank 20 to the seawater inlet 11 of the seawater heat exchange system 10 through the main seawater channel 40.

[0021] As shown in Figure 1, a water pump 50 is used to supply seawater from the seawater holding tank 20 through the main seawater channel 40 to the seawater inlet 11 of the seawater heat exchange system 10. The seawater enters the seawater heat exchange system 10 and exchanges heat with hot coolant (e.g., from the nacelle of a wind turbine generator set) in the seawater heat exchange system 10. After the heat exchange, the cold coolant returns to the heat source to continue cooling the heat source (e.g., the nacelle of a wind turbine generator set). According to an embodiment of the present disclosure, the heated seawater after heat exchange is not discharged directly into the sea, but enters the seawater holding tank 20 through the seawater outlet 12 of the seawater heat exchange system 10 and the hot water bypass 30 connecting the seawater heat exchange system 10 and the seawater holding tank 20.

[0022] According to an embodiment of the present disclosure, the seawater heat exchange system 10, the hot water bypass 30, the seawater holding tank 20 and the seawater main channel 40 form a closed loop, and the temperature of the seawater after one or several heat exchanges will reach 40 to 60°C. When the temperature of the seawater is higher than 30°C, it will cause the embryonic development of marine organisms to stagnate or cause deformities and death, and very few marine organisms can tolerate water temperatures exceeding 35 to 40°C. Therefore, when the seawater after heat exchange enters the seawater holding tank 20 through the hot water bypass 30, the marine organisms in the seawater in the seawater holding tank 20 will be disinfected. Specifically, after the seawater after heat exchange enters the seawater holding tank 20, the marine organisms in the seawater holding tank 20 will be instantly disinfected. In addition, the temperature of the seawater after heat exchange may still exceed 35°C after mixing with the seawater in the seawater holding tank 20, so the marine organisms in the seawater holding tank 20 will be continuously disinfected.

[0023] According to the embodiments of the present disclosure, by utilizing the waste heat of the seawater heat exchange system to bypass hot water and eliminate marine life in the seawater used in the seawater heat exchange system, the system is simple, stable, reliable, and virtually maintenance-free, resulting in excellent economic efficiency. Furthermore, utilizing the waste heat of the seawater heat exchange system to eliminate marine life in the seawater used in the seawater heat exchange system reduces the amount of hot water discharged into the seawater, improves water recycling efficiency, and minimizes the impact on the seawater environment.

[0024] According to an embodiment of the present disclosure, the seawater heat exchange system 10 may be, for example, a tubular heat exchanger, but the present disclosure is not limited thereto; any system capable of achieving heat exchange between seawater and a coolant is sufficient. According to an embodiment of the present disclosure, a water pump 50 may be disposed within the seawater holding tank 20 to supply seawater to the seawater holding tank 20 and to supply the seawater in the seawater holding tank 20 to the seawater inlet 11 of the seawater heat exchange system 10 via the seawater main channel 40. The specific structures of the seawater holding tank 20 and the water pump 50 are not limited. As an example, the water pump 50 may supply preliminarily filtered seawater to the seawater holding tank 20.

[0025] According to an embodiment of the present disclosure, as shown in FIG1 , the marine life suppression system may further include a filter 70, which is disposed upstream of the water pump 50. The water pump supplies seawater filtered by the filter 70 to the seawater holding tank 20. The specific location and structure of the filter 70 are not limited, as long as the filter 70 can filter the seawater entering the seawater holding tank 20.

[0026] According to an embodiment of the present disclosure, as shown in FIG1 , a temperature sensor 31 may be provided on the hot water bypass 30 to sense the water temperature in the hot water bypass 30. According to an embodiment of the present disclosure, as shown in FIG1 , a hot water bypass control valve 32 may also be provided on the hot water bypass 30 to open or close the hot water bypass 30 or to adjust the seawater flow in the hot water bypass 30.

[0027] According to an embodiment of the present disclosure, as shown in FIG1 , the marine life suppression system may further include a main circuit channel 60 connected to the seawater outlet 12. A main circuit control valve 61 is provided on the main circuit channel 60 for opening or closing the main circuit channel 60 or adjusting the seawater flow in the main circuit channel 60.

[0028] According to an embodiment of the present disclosure, to prevent the temperature of the seawater in the seawater holding tank 20 from being too high, which would result in a poor cooling effect, the temperature of the seawater in the seawater holding tank 20 can be appropriately controlled. When the temperature sensed by the temperature sensor 31 is greater than a predetermined value (the predetermined value may be 60°C or higher), the main circuit control valve 61 can be opened and its flow rate adjusted to discharge a portion of the seawater discharged from the seawater outlet 12 into the sea through the main circuit channel 60, thereby reducing the amount of hot seawater flowing into the seawater holding tank 20.

[0029] According to an embodiment of the present disclosure, the technology of using the waste heat of the seawater heat exchange system 10 to inhibit marine life can also be used in conjunction with other traditional marine life inhibition technologies known in the art (for example, electrolytic seawater system, electrolytic copper and aluminum system and direct dosing system).

[0030] The electrolytic seawater system uses an electrolytic cell to electrolyze seawater, producing hypochlorous acid, which can effectively disinfect marine life at a residual chlorine level of 2 to 5 ppm. The electrolytic copper and aluminum system electrolyzes copper and aluminum anodes to produce Cu2O and Al(OH)3. This highly viscous flocculent material is distributed in areas where marine larvae may inhabit, forming a very thin protective layer that inhibits marine life. The direct dosing system can store chemicals and directly add sodium hypochlorite or other non-oxidizing drugs (primarily quaternary ammonium salts, isothiazolinones, quaternary phosphine salts, organic guanidines, etc.) to the system.

[0031] FIG2 illustrates a marine biofilm suppression system according to a second embodiment of the present disclosure. In this system, the technology for suppressing marine biofilm using waste heat from a seawater heat exchange system 10 is combined with an existing seawater electrolysis system. To avoid redundancy, only the components that differ from those of the first embodiment will be described.

[0032] As shown in FIG2 , the marine organism suppression system according to an embodiment of the present disclosure may further include an electrolytic seawater bypass 81 and an electrolytic seawater system 82. Electrolytic seawater bypass 81 connects the seawater outlet 12 to a first connection point 82a of the electrolytic seawater system 82. The electrolytic seawater system 82 is configured to generate hypochlorous acid from the seawater supplied from the seawater outlet 12 and to use the generated hypochlorous acid to disinfect marine organisms in the seawater supplied to the seawater inlet 11. The specific structure of the electrolytic seawater system is not limited, as long as it can generate hypochlorous acid from seawater.

[0033] According to an embodiment of the present disclosure, the electrolytic seawater system 82 is connected to the seawater outlet 12 via the electrolytic seawater bypass 81, and uses the seawater discharged from the seawater outlet 12 to produce hypochlorous acid. Compared to using a separate water pump to extract seawater from the ocean to produce hypochlorous acid, one water pump can be eliminated. Furthermore, the electrolytic seawater system 82 utilizes the seawater discharged from the seawater outlet 12, eliminating the need for further filtration and improving water quality, which helps reduce maintenance costs.

[0034] According to an embodiment of the present disclosure, the technology of using the waste heat of the seawater heat exchange system 10 to suppress marine life can be used interchangeably with the technology of using the seawater electrolysis system to suppress marine life.

[0035] In addition, for the electrolysis seawater system, since the seawater contains calcium and magnesium ions, they will react with OH at the cathode. - Due to reaction fouling, the electrolytic seawater system requires regular acid cleaning and maintenance, with short maintenance cycles. Traditional marine biocontrol technologies require the entire system to be shut down for maintenance (for example, in the wind power sector, the wind turbine generator set must be shut down for maintenance), which impacts the overall system's efficiency.

[0036] According to the embodiments of the present disclosure, the technology for suppressing marine life using the waste heat of the seawater heat exchange system 10 can be used interchangeably with the technology for suppressing marine life using the electrolysis of seawater system. This can avoid the economic losses caused by the need to shut down the traditional marine life suppression system for maintenance, thereby improving the heat exchange efficiency and the overall operating efficiency of the system. In addition, the technology for suppressing marine life using waste heat can effectively disinfect the vast majority of marine life, while the hypochlorous acid produced by the electrolysis of seawater system is mainly effective against larvae and eggs. Alternating the two can improve the disinfecting efficiency and prevent marine life from developing tolerance and causing harm to the system.

[0037] Specifically, the electrolytic seawater bypass 81 may be provided with an electrolytic seawater bypass control valve 81a for opening or closing the electrolytic seawater bypass 81 or adjusting the seawater flow in the electrolytic seawater bypass 81. When the electrolytic seawater bypass control valve 81a is opened, the hot water bypass control valve 32 is closed; when the electrolytic seawater bypass control valve 81a is closed, the hot water bypass control valve 32 is opened.

[0038] According to an embodiment of the present disclosure, when the electrolysis seawater bypass control valve 81a is opened and the hot water bypass control valve 32 is closed, the main circuit control valve 61 can be opened or closed according to the amount of seawater required by the electrolysis seawater system 82. In other words, when the amount of seawater discharged from the seawater discharge port 12 exceeds the amount of seawater required by the electrolysis seawater system 82, the main circuit control valve 61 can be opened to discharge a portion of the heat-exchanged seawater through the main circuit channel 60.

[0039] According to an embodiment of the present disclosure, the seawater electrolysis system 82 may include a primary chloric acid supply port 82b, which is connected to the seawater holding tank 20. Specifically, the hypochlorous acid generated by the seawater electrolysis system 82 may be supplied from the primary chloric acid supply port 82b through the primary chloric acid channel L1 into the seawater holding tank 20 to perform a primary disinfection of marine organisms in the seawater within the seawater holding tank 20. A first residual chlorine detector P1 may be provided within the seawater holding tank 20 for detecting residual chlorine. When the residual chlorine detected by the first residual chlorine detector P1 is between 2 and 5 ppm, effective disinfection of marine organisms can be achieved.

[0040] According to an embodiment of the present disclosure, the seawater electrolysis system 82 may further include a secondary chloric acid supply port 82c, which can be connected to the upstream side of the water pump 50 via a secondary chloric acid channel L2 to perform a secondary disinfection of marine organisms in the seawater before the seawater enters the main seawater channel 40. Similarly, a second residual chlorine detector P2 can be installed at the connection point between the second chloric acid channel L2 and the upstream side of the water pump 50 to detect residual chlorine. When the residual chlorine detected by the second residual chlorine detector P2 is between 2 and 5 ppm, effective disinfection of marine organisms can be achieved.

[0041] According to an embodiment of the present disclosure, the electrolysis seawater system 82 may further include a tertiary chloric acid supply port 82d, which is connected to the downstream side of the seawater main channel 40, specifically, to a position close to the seawater inlet 11 of the seawater heat exchange system 10. The hypochlorous acid generated by the electrolysis seawater system 82 can be supplied from the tertiary chloric acid supply port 82d to the downstream of the seawater main channel 40 through the tertiary chloric acid channel L3 to perform a third disinfection on marine organisms in the seawater downstream of the seawater main channel 40. A third residual chlorine detector P3 can be provided at the connection point between the tertiary chloric acid channel L3 and the seawater main channel 40 for detecting residual chlorine. When the residual chlorine amount detected by the third residual chlorine detector P3 is 2 to 5 ppm, effective disinfection of marine organisms can be achieved.

[0042] FIG3 illustrates a marine growth suppression system according to a third embodiment of the present disclosure. In this system, the technology for suppressing marine growth by utilizing waste heat from a seawater heat exchange system 10 is combined with an existing electrolytic copper and aluminum system. To avoid redundancy, only the components that differ from those of the first embodiment will be described.

[0043] As shown in FIG3 , the marine life suppression system according to an embodiment of the present disclosure may further include an electrolytic copper-aluminum system 90, which is used to produce Cu2O and Al(OH)3 that can form a protective layer. The electrolytic copper-aluminum system 90 is connected to the seawater holding tank 20 and / or the seawater main channel 40 to supply Cu2O and Al(OH)3. As described above, the Cu2O and Al(OH)3 produced by the electrolytic copper-aluminum system 90 are highly viscous flocs, which will be distributed in areas where marine life larvae may inhabit, forming a very thin protective layer, thereby inhibiting marine life. The specific structure of the electrolytic copper-aluminum system 90 is not limited, as long as it can produce Cu2O and Al(OH)3 that can form a protective layer. The position where the electrolytic copper-aluminum system 90 supplies Cu2O and Al(OH)3 is basically the same as the position where the electrolytic seawater system 82 supplies hypochlorous acid. Specifically, the electrolytic copper-aluminum system 90 may include a first supply port 91 connected to the seawater holding tank 20 via a first supply channel M1 to supply Cu2O and Al(OH)3 to the seawater holding tank 20. The electrolytic copper-aluminum system 90 may also include a second supply port 92 connected to the upstream side of the water pump 50 via a second supply channel M2 to supply Cu2O and Al(OH)3 to the upstream side of the filter 70 of the seawater main channel 40. The electrolytic copper-aluminum system 90 may also include a third supply port 93 connected to the downstream side of the seawater main channel 40 via a third supply channel M3, specifically, to a location near the seawater inlet 11 of the seawater heat exchange system 10. According to an embodiment of the present disclosure, seawater discharged from the seawater discharge port 12 can be supplied to the electrolytic copper-aluminum system 90 via a pipeline, and the Cu2O and Al(OH)3 can be dissolved in water before being supplied to the corresponding location. In addition, unused seawater can be discharged to the sea through the main loop channel 60.

[0044] According to the embodiments of the present disclosure, the technology of using the waste heat of the seawater heat exchange system 10 to suppress marine life can be used alternately with the technology of using the electrolytic copper-aluminum system to suppress marine life, thereby avoiding the economic losses caused by the need to shut down the system for maintenance of a traditional marine life suppression system, and improving the heat exchange efficiency and the working efficiency of the entire system.

[0045] In addition, although not shown, in the marine life suppression system according to the embodiment of the present disclosure, the technology of using the waste heat of the seawater heat exchange system 10 to suppress marine life can also be used in combination with the existing direct dosing system.

[0046] That is, according to an embodiment of the present disclosure, the marine life inhibition system may further include a direct dosing system, which stores agents capable of disinfecting marine life, and the direct dosing system is connected to the seawater holding tank 20 and / or the seawater main channel 40 to supply agents.

[0047] As mentioned above, the direct dosing system can store drugs and directly add sodium hypochlorite or other non-oxidizing drugs (mainly quaternary ammonium salts, isothiazolinones, quaternary phosphine salts, organic guanidines, etc.) to the system. For the direct dosing system, regular maintenance is required. According to the embodiment of the present disclosure, the technology of using the waste heat of the seawater heat exchange system 10 to inhibit marine life can be used alternately with the technology of using the direct dosing system to inhibit marine life, thereby avoiding the economic losses caused by the need to shut down the system for maintenance of a traditional marine life inhibition system, and improving the heat exchange efficiency and the working efficiency of the entire system.

[0048] As an example, the first dosing point of the direct dosing system can be connected to the seawater holding tank 20, the second dosing point of the direct dosing system can be connected to the upstream of the water pump 50, and the third dosing point of the direct dosing system can be connected to the downstream side of the seawater main channel 40 (specifically, connected to a position close to the seawater inlet 11 of the seawater heat exchange system 10).

[0049] According to another embodiment of the present disclosure, a wind turbine generator set including the above-mentioned marine life suppression system may also be provided.

[0050] According to the present disclosure, by utilizing the waste heat of a seawater heat exchange system to bypass hot water and eliminate marine life in the seawater used in the seawater heat exchange system, the system is simple, stable, reliable, and virtually maintenance-free, resulting in excellent economic efficiency. Furthermore, utilizing the waste heat of the seawater heat exchange system to eliminate marine life in the seawater used in the seawater heat exchange system reduces the amount of hot water discharged into the seawater, improves water recycling efficiency, and minimizes the impact on the seawater environment.

[0051] In addition, according to the present disclosure, the technology of using the waste heat of the seawater heat exchange system to inhibit marine life can be used alternately with the traditional technology of inhibiting marine life, which can avoid the economic losses caused by the need to shut down the system for maintenance of a traditional marine life inhibition system, improve the heat exchange efficiency and the working efficiency of the entire system, and at the same time improve the disinfection efficiency.
