Description

Technical Field

[0001] This invention belongs to the field of diesel engine technology, and particularly relates to an installation mechanism suitable for a marine diesel engine water treatment system and a marine diesel engine. Background Technology

[0002] The Intelligent Controlled Exhaust Gas Recirculation (iCER) system is an environmentally friendly and efficiency-enhancing technology applicable to dual-fuel low-speed engines. Its basic design principle involves washing and cooling a portion of the main engine's exhaust gas before introducing it into the compressor inlet of the main engine's turbocharger, where it mixes with fresh air. This controls the oxygen concentration in the scavenging gas, optimizing the combustion process and improving the thermal efficiency of dual-fuel engines in gas combustion mode. The water treatment system is a crucial component of the iCER system, used to treat condensate from the air cooler and circulating overflow wastewater, ensuring it meets emission standards before discharge.

[0003] The existing water treatment system has low integration of its components, which are usually scattered throughout the workshop, making transportation and disassembly difficult and resulting in low overall efficiency. This can affect the commissioning cycle of subsequent dual-fuel generators. Furthermore, the commissioning of dual-fuel generators requires the coordinated operation of the iCER train, leading to a high overall space occupancy rate for related equipment and reducing the utilization rate of the workshop's internal space.

[0004] Therefore, there is an urgent need to propose an installation mechanism and a marine diesel engine suitable for marine diesel engine water treatment systems in order to solve the above problems. Summary of the Invention

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-9As shown, this embodiment provides an installation mechanism suitable for a marine diesel engine water treatment system. The marine diesel engine water treatment system includes a venting tank 100, a neutralization tank 200, an alkali tank 300, a PAC dosing module 400, and an air flotation water treatment module 500, arranged at intervals. The installation mechanism suitable for the marine diesel engine water treatment system includes a mounting bracket 1, a neutralization tank mounting frame 2, and a water treatment module mounting frame 3. The mounting bracket 1 is provided with a first preset installation area, a second preset installation area, and a third preset installation area. The first and second preset installation areas are spaced apart along a first direction and are both... The third preset installation area is set at intervals along the second direction, and the first direction is set at an angle to the second direction. The alkali tank 300 and the PAC dosing module 400 are installed at intervals along the second direction in the second preset installation area. The third preset installation area is used to install the discharge tank 100. The neutralization cabinet mounting frame 2 protrudes vertically in the second preset installation area and is used to install the neutralization cabinet 200. The water treatment module mounting frame 3 protrudes vertically in the first preset installation area and is used to install the air flotation water treatment module 500. The height of the water treatment module mounting frame 3 is higher than the height of the neutralization cabinet mounting frame 2.

[0025] In this embodiment, the mounting bracket 1 is divided into a first preset installation area, a second preset installation area, and a third preset installation area. The air flotation water treatment module 500 is installed in the water treatment module mounting frame 3 in the first preset installation area. The neutralization cabinet 200 is installed in the neutralization cabinet mounting frame 2 in the second preset installation area. The alkali cabinet 300 and the PAC dosing module 400 are installed at intervals along the second direction in the second preset installation area of ​​the mounting bracket 1. The venting cabinet 100 is installed in the third preset installation area. Through the above structural settings, the marine diesel engine water treatment system is integrated into the installation mechanism for marine diesel engine water treatment system proposed in this embodiment, which improves the integration of the various components of the marine diesel engine water treatment system, reduces the area occupied by the marine diesel engine water treatment system, facilitates the planning of the workshop site, and optimizes the utilization rate of the internal space of the workshop. The first, second, and third pre-designated installation areas on the mounting bracket 1, together with the neutralization cabinet mounting frame 2 and the water treatment module mounting frame 3, provide installation benchmarks for the various components of the marine diesel engine water treatment system. This improves the efficiency and convenience of disassembly and assembly of the marine diesel engine water treatment system, reduces the overall difficulty of disassembly and assembly, and enhances the ease of transport and subsequent water treatment process efficiency. Furthermore, the height of the water treatment module mounting frame 3 is higher than that of the neutralization cabinet mounting frame 2, reducing the difficulty of the neutralized wastewater flowing from the neutralization cabinet 200 to the coagulation tank of the flotation water treatment module 500, thus ensuring the treatment efficiency and effectiveness of the subsequent flotation water treatment module 500.

[0026] Optionally, such as Figure 1 and Figure 2 As shown, the water treatment module mounting frame 3 includes multiple first legs 31 and a mounting bracket 32. The multiple first legs 31 are all located in a first preset installation area and connected to the mounting support 1. The mounting bracket 32 ​​is located on the upper part of the multiple first legs 31 and connected to them. The mounting bracket 32 ​​is used to mount the air-flotation water treatment module 500. This structural design improves the overall structural integrity of the water treatment module mounting frame 3 and the mounting support 1, ensuring the stability of the water treatment module mounting frame 3 in supporting the air-flotation water treatment module 500. In this embodiment, the multiple first legs 31 are all H-beams, and both the mounting support 1 and the mounting bracket 32 ​​are assembled from H-beams. The multiple first legs 31 are welded to the mounting support 1 and the mounting bracket 32 ​​respectively, improving the structural integrity and strength of the water treatment module mounting frame 3. The air-flotation water treatment module 500 is bolted to the mounting bracket 32 ​​to ensure the convenience of disassembly, assembly, and maintenance of the air-flotation water treatment module 500.

[0027] Specifically, a connecting and reinforcing diagonal brace 33 is provided between the first leg 31 and the mounting support 1. The addition of the connecting and reinforcing diagonal brace 33 increases the contact area between the water treatment module mounting frame 3 and the mounting support 1, improves the connection strength and stability between the two, and extends the service life of the water treatment module mounting frame 3.

[0028] Optionally, such as Figure 1 and Figure 7 As shown, the neutralization cabinet mounting frame 2 includes at least two second legs 21 and a mounting platform 22. The at least two second legs 21 are both located in the second preset mounting area and connected to the mounting support 1. The mounting platform 22 is located on top of the second legs 21, and the at least two second legs 21 are connected to the mounting platform 22. The mounting platform 22 is used to mount the neutralization cabinet 200. This configuration improves the structural integrity of the neutralization cabinet mounting frame 2 and the mounting support 1, ensuring the stability of the neutralization cabinet mounting frame 2's subsequent support for the neutralization cabinet 200. A connecting reinforcement plate 23 can be provided between adjacent second legs 21 to enhance the connection strength between adjacent second legs 21, thereby ensuring the reliability of the second legs 21's support for the mounting platform 22. In this embodiment, the second leg 21 is an H-beam, the mounting bracket 1 is assembled from H-beams, the second leg 21 is welded to the mounting bracket 1, the mounting platform 22 and the connecting reinforcement plate 23 are both steel plates, both of which are welded to the second leg 21, and the neutralization cabinet 200 is mounted on the mounting platform 22 with bolts to ensure the convenience of disassembly, assembly and maintenance of the neutralization cabinet 200.

[0029] In this embodiment, the first, second, and third preset installation areas are all provided with multiple collection tanks 11 spaced apart. The installation mechanism for the marine diesel engine water treatment system also includes multiple water collection trays 12 corresponding one-to-one with the collection tanks 11. The water collection trays 12 are detachably installed in the collection tanks 11 and are used to collect leaked liquid from the marine diesel engine water treatment system. The multiple water collection trays 12 are installed one-to-one with the multiple collection tanks 11 in the first, second, and third preset installation areas. The installation of the water collection trays 12 effectively collects leaked liquid during water treatment operations of the marine diesel engine water treatment system, improves the cleanliness of the surrounding environment of the installation mechanism for the marine diesel engine water treatment system, and reduces safety hazards for personnel passing through. The detachable installation of the water collection trays 12 in the collection tanks 11 improves the convenience and efficiency of disassembly and assembly, and reduces the difficulty of disassembling and assembling the water collection trays 12.

[0030] Specifically, such as Figure 5 and Figure 8 As shown, at least one side wall of the water collection tray 12 is provided with a threaded connector 13, which is threadedly connected to the wall of the collection tank 11. The water collection tray 12 is threadedly connected to the wall of the collection tank 11 by means of the threaded connector 13, which not only ensures the stability of the connection between the water collection tray 12 and the wall of the collection tank 11 and the convenience of disassembling and assembling the water collection tray 12, but also allows for flexible adjustment of the height of the water collection tray 12 on the side with the threaded connector 13 relative to the mounting support 1, which facilitates the adjustment of the tilt angle of the water collection tray 12 and improves the discharge efficiency of the liquid in the water collection tray 12.

[0031] More specifically, the threaded connector 13 has a vertically extending liquid channel. A detachable plug is installed at the upper part of the liquid channel, and the lower part connects to a drainage pipe. The plug at the upper part of the liquid channel effectively utilizes the water collection space of the collection tray 12, while the connection to the drainage pipe at the lower part reduces the size requirement of the water collection space of the collection tray 12, thus reducing the area occupied by the collection tray 12. This reduces the overall space occupancy of the installation mechanism suitable for marine diesel engine water treatment systems and the risk of structural interference with the marine diesel engine water treatment system. The detachable plug at the upper part of the liquid channel improves the flexibility and convenience of installation and removal, allowing for flexible switching between the water collection space and the liquid channel connection state. Understandably, when the water collection space of the collection tray 12 is not completely filled with liquid, the plug can be placed at the upper part of the liquid channel to isolate the water collection space and the liquid channel, facilitating full utilization of the water collection space of the collection tray 12. When the liquid is about to fill the water collection space, the sealing piece can be removed to connect the water collection space and the liquid channel, preventing excessive leakage and overflow of the water collection pan 12, which could cause safety hazards. A liquid level sensor can be installed in the water collection space of the water collection pan 12. The liquid level sensor is electrically connected to a control unit that can acquire its liquid level detection data, which facilitates construction personnel to remotely monitor the liquid level height in the water collection pan 12.

[0032] Optionally, such as Figure 1 and Figure 3 As shown, the second preset installation area has an installation groove 14. The installation mechanism suitable for marine diesel engine water treatment systems also includes a first support member 15 and a second support member 16, both extending along a second direction. The first support member 15 and the second support member 16 are spaced apart along a first direction in the installation groove 14 and are used to jointly support the PAC dosing module 400. The first support member 15 and the second support member 16 provide an installation positioning reference for the PAC dosing module 400, reducing the installation difficulty of the PAC dosing module 400 and improving the installation efficiency of the PAC dosing module 400. The PAC dosing module 400 is jointly supported by the first support member 15 and the second support member 16, which enhances the reliability and safety of the support for the PAC dosing module 400 compared to using a single support rod.

[0033] Specifically, at least one of the first support member 15 and the second support member 16 slides in the mounting groove 14 along the first direction, thereby enabling flexible adjustment of the distance between the first support member 15 and the second support member 16 along the first direction. This satisfies the stable installation requirements of the first support member 15 and the second support member 16 for PAC dosing modules 400 with different dimensions along the first direction, and enhances the versatility of the first support member 15 and the second support member 16 in supporting PAC dosing modules 400 of different sizes. Understandably, after the spacing between the first support member 15 and the second support member 16 is adjusted, the components that slide in the mounting groove 14 can be locked with fasteners such as bolts or fastening pins. Alternatively, the components that slide in the mounting groove 14 can be welded to the mounting bracket 1 to improve the overall structural integrity of the first support member 15, the second support member 16, and the mounting bracket 1. Then, the PAC dosing module 400 can be fastened to the first support member 15 and the second support member 16 with fasteners such as bolts or fastening pins to further improve the support stability of the first support member 15 and the second support member 16 for the PAC dosing module 400, ensuring the safety of the PAC dosing module 400 during transport and the stable operation of subsequent dosing operations.

[0034] In this embodiment, the installation mechanism for the marine diesel engine water treatment system further includes a lifting auxiliary unit 4. The lifting auxiliary unit 4 includes first lifting lugs 41 and second lifting lugs 42, both used for connecting to lifting equipment. At least two first lifting lugs 41 are spaced apart on the top surface of the mounting support 1, and at least two second lifting lugs 42 are spaced apart on the top surface of the water treatment module mounting frame 3. The presence of first lifting lugs 41 on the mounting support 1 and second lifting lugs 42 on the water treatment module mounting frame 3, along with the placement of first lifting lugs 41 and second lifting lugs 42 at different heights of the installation mechanism for the marine diesel engine water treatment system, all capable of connecting to lifting equipment, improves the convenience and reliability of subsequent transportation of the marine diesel engine water treatment system using lifting equipment. It also reduces the swaying amplitude of the installation mechanism during transportation, thereby enhancing the transportation safety of the marine diesel engine water treatment system integrated into the installation mechanism. The first lifting lug 41 and the second lifting lug 42 are each provided with at least two, which increases the contact area with the lifting equipment, reduces the safety risks of lifting, and improves the safety and stability of lifting.

[0035] Specifically, the installation mechanism for the marine diesel engine water treatment system also includes a lifting and reinforcement unit 5. The lifting and reinforcement unit 5 includes a first lifting reinforcement component 51 fixedly connected to the first lifting lug 41 and a second lifting reinforcement component 52 fixedly connected to the second lifting lug 42. At least a portion of the first lifting reinforcement component 51 is embedded in the mounting support 1, and at least a portion of the second lifting reinforcement component 52 is embedded in the water treatment module mounting frame 3. The addition of the first lifting reinforcement component 51 improves the connection strength between the first lifting lug 41 and the mounting support 1, and the addition of the second lifting reinforcement component 52 improves the connection strength between the second lifting lug 42 and the mounting support 1. The combination of the first lifting reinforcement component 51 and the second lifting reinforcement component 52 enables the first lifting lug 41, the second lifting lug 42, and the mounting support 1 to work together during the subsequent lifting of the installation mechanism for the marine diesel engine water treatment system, further improving the lifting reliability of the installation mechanism and reducing the operational risks caused by connection failures at the lifting points.

[0036] In other embodiments, the bottom of the mounting bracket 1 is rotatably equipped with at least two lockable wheels. The addition of wheels improves the ease and flexibility of transporting the marine diesel engine water treatment system installed on the mounting mechanism, thereby increasing the transport efficiency. The lockable wheels ensure the positional accuracy of the mounting mechanism after it is in place, improving the transport reliability of the marine diesel engine water treatment system.

[0037] Optionally, such as Figure 4 and Figure 5 As shown, the bottom of the mounting bracket 1 is equipped with multiple elastic support pads 17 to absorb external vibration loads during transportation or vibration energy generated during the operation of various components of the marine diesel engine water treatment system. This reduces rigid collisions between the components of the marine diesel engine water treatment system and the installation mechanism suitable for the system, extends the service life of both components and the installation mechanism, and lowers maintenance costs. The multiple elastic support pads 17 at the bottom of the mounting bracket 1 also ensure that the mounting bracket 1 maintains a certain distance from the workshop floor, improving the heat dissipation of the components of the marine diesel engine water treatment system.

[0038] For example, the installation mechanism for a marine diesel engine water treatment system also includes a maintenance ladder 6, which is located on the side facing the control box of the air flotation water treatment module 500. The maintenance ladder 6 is mounted on the mounting support 1 and connected to the water treatment module mounting frame 3. This configuration achieves structural integrity of the maintenance ladder 6, the water treatment module mounting frame 3, and the mounting support 1, reducing manual labor intensity and improving maintenance convenience compared to requiring workers to carry the ladder during maintenance.

[0039] Specifically, such as Figure 1 , Figure 2 and Figure 9 As shown, the maintenance ladder 6 includes a handrail bend 61, a footrest 62, a maintenance platform 63, and a reinforcing pipe section 64. The handrail bend 61 extends vertically and connects to the water treatment module mounting frame 3, providing a gripping position for workers to perform maintenance at height. The footrest 62 is spaced vertically at intervals along the handrail bend 61, facilitating workers' access for work at height. The maintenance platform 63 is located above the footrest 62 and connects to the water treatment module mounting frame 3, allowing workers to stand here to perform maintenance on the control box of the air flotation water treatment module 500. The reinforcing pipe section 64 extends in a first direction, connecting at both ends to the handrail bend 61 and the water treatment module mounting frame 3, increasing the connection strength and reliability between the handrail bend 61 and the water treatment module mounting frame 3, and improving the safety of workers during maintenance. A reinforcing support leg 65 can be added at the connection between the reinforced pipe section 64 and the water treatment module mounting frame 3 to further enhance the reliability of the connection. The maintenance platform 63 can be made of patterned steel plate, which is aesthetically pleasing and has good anti-slip performance.

[0040] Optionally, the footboard 62 can be a square steel pipe with its edges welded upwards. The square steel pipe has a regular cross-section, strong bending and torsional resistance, strong deformation resistance, and high load-bearing stability. Welding the square steel pipe with its edges facing upwards can reduce the risk of slipping for construction workers during the climbing process, further improving the safety of construction workers climbing at heights.

[0041] This embodiment also proposes a marine diesel engine, including a marine diesel engine water treatment system and an installation mechanism as described above suitable for the marine diesel engine water treatment system. An alkali tank 300 and a PAC dosing module 400 are installed at intervals along a second direction in a second preset installation area. A venting tank 100 is installed in a third preset installation area. A neutralization tank 200 is installed in a neutralization tank mounting frame 2, and an air flotation water treatment module 500 is installed in a water treatment module mounting frame 3. This structural arrangement allows the various parts of the marine diesel engine water treatment system to be arranged in an orderly and partitioned manner within the installation mechanism suitable for the marine diesel engine water treatment system. This improves the integration of the marine diesel engine water treatment system, optimizes its space utilization, reduces the difficulty of disassembly and assembly, reduces interference between its components, lowers the difficulty of connecting pipelines between cooperating components, and ensures the safety and reliability of the collaborative operation of the various components of the marine diesel engine water treatment system. It is understood that the water treatment operation principle of the marine diesel engine water treatment system in this embodiment is prior art and will not be elaborated further here.

[0042] Specifically, the marine diesel engine water treatment system also includes a water pump 600, which is installed on the connecting pipeline between the vent tank 100 and the neutralization tank 200. The water pump 600 is used to pump the liquid from the vent tank 100 to the neutralization tank 200, improving the efficiency of water treatment operations. The water pump 600 is located in a second pre-designated installation area and is bolted to the mounting support 1, improving the ease of installation and removal of the water pump 600 and the structural integrity of the water pump 600 and the mounting support 1.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
