Description

Technical Field

[0001] The invention relates to the field of ship ballast water treatment, in particular to a ship ballast water treatment device with pretreatment and a treatment method thereof. Background Art

[0002] In short, ship ballast water refers to the water specially added to the ballast tanks on board to maintain the stability and safety of the ship under various working conditions. The water can be either fresh water or sea water, and even include some suspended matter. The main function of ballast water is to adjust or control the key parameters of the ship such as heel, trim, draft, stability, vibration and strength to ensure that the ship can maintain the best operating state under various complex sea conditions and loading conditions. The ship's ballast water needs to be processed by treatment equipment to remove debris, suspended particles, bacteria and microorganisms, etc., to avoid affecting the environment of the next driving area.

[0003] For example, a Chinese patent with announcement number CN110902900A discloses a ship ballast water treatment equipment, including a pretreatment box, a sterilization box 1 and a sterilization box 2, the pretreatment box having a water inlet and a pre-discharge port, and a partition is arranged inside the pretreatment box; the partition is transversely installed in the pretreatment box and divides the inner cavity of the pretreatment box into a driving cavity and a pretreatment cavity, the pretreatment cavity is connected with the pre-discharge port and the water inlet, and a filter plate is obliquely arranged in the pretreatment cavity; a driving cylinder is installed in the driving cavity, and the output shaft of the driving cylinder passes through the partition and extends into the pretreatment cavity, and the end of the output shaft is connected to the filter plate; the sterilization box 1 is located outside the pretreatment box and is connected with the pretreatment cavity through a water conduit 1, and a sterilization component is arranged in the cavity of the sterilization box 1.

[0004] Although the above-mentioned patent has solved the problem that the disinfection and sterilization method is too single and cannot fully kill bacteria and microorganisms in ballast water, resulting in poor sterilization effect, the existing ballast water treatment equipment still has some defects. When large organisms enter the pretreatment tank, in order to prevent them from clogging the inside of the tank, the traditional method is to use a flushing pipe to flush them out. However, in this process, some organisms are often unable to escape and are trapped in the pretreatment tank, which not only affects the treatment efficiency of the equipment, but also may pose a potential threat to the subsequent treatment process. More importantly, the use of a large amount of water for flushing is undoubtedly a huge waste of resources and does not conform to the current environment of energy conservation and emission reduction. In addition, although drug combination sterilization can show good sterilization effect in some cases, long-term use of the same drug combination may lead to enhanced drug resistance of microorganisms, which will not only reduce the sterilization effect, but also may have potential negative impact on the ecological environment. At the same time, the problem of drug residues cannot be ignored. Once these chemical residues enter the water body, they may cause harm to aquatic organisms and the entire ecosystem, and even affect human health through the food chain. Furthermore, from an economic point of view, long-term reliance on drug combination sterilization will undoubtedly increase the procurement cost of the agent and increase the overall processing cost, which is not conducive to the sustainable development of the enterprise. Therefore, improvements are made to the above problems. Summary of the invention

[0015] A treatment method for a ship ballast water treatment device with pretreatment, comprising the following steps:

[0016] S1. The ship's ballast water is introduced through the liquid inlet pipe. Small organisms in the ballast water enter the treatment tank through the pusher baffle net, and large organisms in the ballast water are blocked by the pusher baffle net so that they cannot enter the treatment tank;

[0017] S2, next, the first driving mechanism drives the mounting assembly, so that the mounting assembly drives the pushing material blocking net to move in the liquid inlet pipe, and pushes the large organisms staying in the liquid inlet pipe out of the liquid inlet pipe;

[0018] S3, driving the cleaning brush to move on the material pushing retaining net through the second driving mechanism, and the bristles of the brush extend into the material pushing retaining net to clean the filter net, so that the filter net is kept clean;

[0019] S4. After the ballast water is pre-treated, it passes through a high-precision filter to effectively remove large particles of impurities and suspended solids, providing a purer water quality foundation for subsequent disinfection treatment;

[0020] S5. After the ballast water enters the bottom of the treatment box, the ozone generated by the ozone generator is injected into the treatment box through the jet hole on the assembly plate to disinfect the ballast water. At the same time, the ultraviolet lamp on the assembly plate irradiates the ballast water with ultraviolet light to further enhance the disinfection effect.

[0021] S6. During the disinfection process, the assembly plate is moved back and forth through the reciprocating mechanism to evenly distribute the ozone and ultraviolet rays, thereby improving the disinfection effect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Firstly, in the present invention, a pushing material blocking net is installed in the liquid inlet pipe to prevent large organisms from entering the interior of the treatment box from the liquid inlet pipe. When the large organisms in the liquid inlet pipe need to be taken out, the first driving mechanism is used to drive the installation component to move, and the installation component drives the pushing material blocking net to move, so that the pushing material blocking net moves in the liquid inlet pipe to bring out the large organisms that have stayed there, ensuring that all large organisms can escape smoothly, avoiding clogging of the liquid inlet pipe and affecting the operation of the treatment box, and the use cost is lower than that of the water flushing method, thereby providing a strong guarantee for the subsequent ballast water treatment work and reducing the danger of the subsequent treatment process.

[0024] Secondly, in the present invention, a connecting frame is installed on the pushing baffle net, and a second driving mechanism is installed on the connecting frame. The second driving mechanism is used to drive the cleaning brush to move on the pushing baffle net, so as to achieve comprehensive and effective cleaning of impurities inside the pushing baffle net and prevent blockage of the liquid inlet pipe. This not only extends the service life of the pushing baffle net, but also ensures its continuous and efficient operation in the long-term working process, thereby further improving the reliability of the entire ballast water treatment system.

[0025] Thirdly, in the present invention, by installing an assembly plate in the treatment box, and installing a jet hole connected to an ultraviolet lamp and an ozone generator on the assembly plate, the ballast water in the treatment box can be sterilized. Ozone sterilization can destroy the biological structure of bacteria, viruses and other microorganisms in a relatively short time, making them inactive, thereby achieving the purpose of sterilization. Ozone sterilization is not limited to surface sterilization, but can also penetrate into tiny gaps for sterilization, and will not produce drug resistance. Ozone will decompose into oxygen in water by itself, and will not leave harmful chemical residues. Therefore, it is considered to be a pollution-free disinfectant. No harmful substances are produced during the ozone treatment process, which is environmentally friendly. No additional chemicals need to be added during the ozone treatment process, so the cost of medicines can be saved.

[0026] Fourthly, in the present invention, a reciprocating mechanism is installed in the treatment box, and the reciprocating mechanism is used to drive the jet holes connected to the ultraviolet lamp and the ozone generator to move back and forth, which greatly improves the uniformity and comprehensiveness of sterilization and disinfection. The jet holes connected to the ultraviolet lamp and the ozone generator are driven by the reciprocating mechanism to ensure that most microorganisms are effectively killed and inhibited, thereby avoiding the problem of sterilization dead corners that may exist in traditional fixed sterilization equipment. As the ultraviolet lamp and the ozone generator move back and forth in the treatment box, they can contact and act with the microorganisms more quickly, thereby shortening the sterilization cycle and improving the overall treatment efficiency.

[0044] A treatment method for a ship ballast water treatment device with pretreatment, comprising the following steps:

[0045] S1. The ship's ballast water is introduced through the liquid inlet pipe 2. Small organisms in the ballast water enter the treatment tank 1 through the pusher block net 4. Large organisms in the ballast water are blocked by the pusher block net 4 so that they cannot enter the treatment tank 1.

[0046] S2, next, the first driving mechanism 6 drives the mounting assembly 5, so that the mounting assembly 5 drives the pushing material blocking net 4 to move in the liquid inlet pipe 2, and pushes the large organisms staying in the liquid inlet pipe 2 out of the liquid inlet pipe 2;

[0047] S3, the cleaning brush 10 is driven by the second driving mechanism 9 to move on the material pushing baffle 4, and the bristles of the brush extend into the material pushing baffle 4 to clean the filter 13, so that the filter 13 is kept clean;

[0048] S4. After the ballast water is pre-treated, it passes through a high-precision filter 13, so that large particles of impurities and suspended solids are effectively removed, providing a purer water quality foundation for subsequent disinfection treatment;

[0049] S5. After the ballast water enters the bottom of the treatment box 1, the ozone generated by the ozone generator 17 is injected into the treatment box 1 through the jet hole 15 on the assembly plate 14 to disinfect the ballast water. At the same time, the ultraviolet lamp 16 on the assembly plate 14 irradiates the ballast water with ultraviolet light to further enhance the disinfection effect.

[0050] S6. During the disinfection process, the assembly plate 14 is moved back and forth by the reciprocating mechanism 18 to evenly distribute the ozone and ultraviolet rays, thereby improving the disinfection effect.

[0051] The working principle of the present invention is as follows: ballast water enters through the liquid inlet pipe 2, and the pusher blocking net 4 can prevent large organisms from entering the treatment box 1. When it is necessary to take out the large organisms that may stay in the liquid inlet pipe 2, the first motor 62 is used to drive the first sprocket 63 to rotate, and the first sprocket 63 drives the second sprocket 65 to rotate through the transmission chain 64. The first sprocket 63 and the second sprocket 65 drive the transmission rod 66 to rotate. When the transmission rod 66 rotates, the first bevel gear 671 rotates, the first bevel gear 671 drives the second bevel gear 672 to rotate, and the second bevel gear 672 drives the first screw rod 673 to rotate, which can drive the push rod 54 to move, the push rod 54 drives the connecting block 53 to move, and the connecting block 53 drives the connecting rod 52 to move , so that the connecting rod 52 drives the pushing material blocking net 4 to move in the liquid inlet pipe 2, and the pushing material blocking net 4 moves in the liquid inlet pipe 2 to bring out the large organisms that have stayed there, ensuring that all large organisms can escape smoothly, avoiding blocking the liquid inlet pipe 2 and affecting the operation of the treatment box 1, and the use cost is lower than that of the water flushing method, thereby providing a strong guarantee for the subsequent ballast water treatment work and reducing the danger of the subsequent treatment process. When it is necessary to move the cleaning brush 10, the second motor 91 is used to drive the second screw rod 92 to rotate, so that the moving plate 93 on its surface moves on the inner side of the connecting frame 8, so that the moving plate 93 drives the brush holder 94 to move, and the brush holder 94 drives the cleaning brush 10 to move, and the third motor 95 controls the cleaning brush 10 to rotate to clean the pushing material blocking net 4, preventing the pushing material blocking net 4 from being blocked. The material retaining net 4 is blocked, and the first spring 96 is provided to make the cleaning brush 10 maintain elastic contact with the material pushing retaining net 4, which is beneficial to the work of the cleaning brush 10. The elasticity of the spring can also help the cleaning brush 10 overcome a certain resistance during the movement and maintain a continuous cleaning action. After the ballast water enters the treatment box 1, the ozone generated by the ozone generator 17 enters the assembly plate 14 through the hose and then is ejected through the jet hole 15. When the ozone gas is ejected through the jet hole 15, it will form tiny bubbles. These bubbles will release ozone molecules during the process of rising in the water, react with microorganisms and pollutants in the water, and cooperate with the ultraviolet lamp 16. The ultraviolet lamp 16 can emit ultraviolet radiation of a specific wavelength, which can destroy microorganisms. DNA structures, thereby killing or inactivating them. When it is necessary to move the ultraviolet lamp 16 and the jet hole 15 in the processing box 1, the fourth motor 187 is used to drive the driving gear 186 to rotate, drive the rack 184 to move, and the rack 184 drives the moving block 183 to move. The moving block 183 moves stably under the action of the second slide bar 182, thereby driving the assembly plate 14 to move. After the rack 184 moves, it drives the driven gear 185 to rotate forward. As the driving gear 186 rotates, the driving gear 186 also drives the driven gear 185 to rotate in the opposite direction, so that the rack 184 drives the moving block 183 to control the assembly plate 14 to reset, so that the assembly plate 14 moves back and forth, avoiding the sterilization dead angle problem that may exist in traditional fixed sterilization equipment.As the ultraviolet lamp 16 and the ozone generator 17 move back and forth in the treatment box 1, they can contact and act on the microorganisms more quickly, thereby shortening the sterilization cycle and improving the overall treatment efficiency.
