Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a marine gas-liquid separator and a ship. Background Technology

[0002] A gas-liquid separator is required in the cooling water circulation system of marine diesel engines to remove air from the high-temperature cooling water and prevent damage to system components due to cavitation. The arrangement of the gas-liquid separator needs to be stable, and the precision requirements for connecting external pipelines to the inlet and outlet water pipes are also relatively high. With the increase in the number of cylinders and cylinder diameter in marine low-speed engines, the required cooling water flow rate increases significantly, and the original gas-liquid separator is no longer sufficient.

[0003] Existing technical solutions typically involve directly welding the gas-liquid separator to the main engine body using a vertical plate. However, this method uses a small gas-liquid separator, which cannot meet the cooling water requirements of marine diesel engines. On the other hand, when using a method that fixes a larger gas-liquid separator to a bracket using a support, the difficulty in welding and installing the large gas-liquid separator, as well as issues with the machining and welding precision of parts, often leads to errors during assembly. This requires adjusting the height by adding shims or grinding flanges when welding the support, which is time-consuming, labor-intensive, and inconvenient due to the need to replace or re-machine parts. Summary of the Invention

[0024] Optionally, the drain pipe includes a second ball valve located at the end of the drain pipe away from the bottom of the tank, for opening when draining liquid accumulated in the tank, so as to allow the drain pipe to drain the accumulated liquid.

[0037] This invention provides a marine gas-liquid separator that can be used for gas-liquid separation in marine diesel engine cooling water circulation systems. Figure 1 This is a schematic diagram of the structure of a marine gas-liquid separator provided in an embodiment of the present invention. See also: Figure 1 The gas-liquid separator includes: tank body 1, inlet pipe 2, outlet pipe 3, vent pipe 4, drain pipe 5, and support assembly 6;

[0038] Tank 1 is used for gas-liquid separation;

[0039] The water inlet pipe 2 is located on the outer wall of the tank 1 and is used to inject liquid containing gas;

[0040] The water outlet pipe 3 is located on the outer wall of the tank body 1, and the water outlet pipe 3 and the water inlet pipe 2 are located on both sides of the tank body 1 to discharge the liquid after the gas separation.

[0041] A vent pipe 4 is located at the top of the tank 1 and is used to discharge the separated gas.

[0042] The drain pipe 5 is located at the bottom of the tank 1 and is used to drain accumulated liquid;

[0043] The support assembly 6 is movably connected to the side wall of the tank 1 and is used to adjust and fix the support tank 1.

[0044] Specifically, the tank body 1 includes a tank top 11 and a tank bottom 12, both of which can be hemispherical structures; the water outlet pipe 3 is higher than the tank bottom. The hemispherical design of the tank top 11 and tank bottom 12 is conducive to the accumulation of gas and liquid, has high strength and is not easily deformed, can reduce welding, and has a simpler process and a more aesthetically pleasing appearance. The height of the inlet pipe 2 and outlet pipe 3 on the outer wall of the tank body 1 can be set according to the piping layout of the entire marine low-speed diesel engine main engine system. Since the gas and liquid need to be separated as much as possible, a certain height difference must be maintained between the inlet pipe 2 and the outlet pipe 3 to allow the fluid to move fully in the tank. Therefore, the positions of the inlet pipe 2 and the outlet pipe 3 should be close to the top 11 and bottom 12 of the gas-liquid separator, respectively, to ensure a sufficient height difference between them. However, if the outlet pipe 3 is too low, it will generate noise and pose a safety hazard. Therefore, the position of the outlet pipe 3 cannot be set too low. In order to ensure the stability of the gas-liquid separator structure, the height of the inlet pipe 2 and the outlet pipe 3 welded to the outer wall of the tank body 1 should be symmetrically set so that the center of gravity of the gas-liquid separator can be kept in the center of the tank body 1, and the structure is stable. For example, the inlet pipe 2 can be located at the upper 1 / 5 of the side wall of the tank 1, arranged tangentially to the tank wall; the outlet pipe 3 is located at the lower 1 / 5 of the side wall of the tank 1, also arranged tangentially to the tank wall. Preferably, the diameter of the inlet pipe 2 is equal to the diameter of the outlet pipe 3, which ensures a relatively stable flow velocity of the fluid entering and exiting the tank 1, allowing for sufficient separation of gas and liquid in the fluid. The diameter of the tank 1 is three times the diameter of the inlet pipe 2, ensuring a sufficiently long travel distance for the fluid within the tank 1, i.e., the rotating liquid flow path formed by the fluid within the tank 1, guaranteeing sufficient fluid movement and thorough separation of gas and liquid in the fluid. However, the diameter of the tank 1 is not limited to three times the diameter of the inlet pipe 2; it can be set according to the fluid flow rate, ensuring sufficient fluid movement within the tank 1.

[0045] When a fluid containing gas enters the tank 1 through the inlet pipe 2, a rotating liquid flow is formed inside the tank 1. After sufficient movement within the tank 1, due to density differences, the gas accumulates at the top 11 of the tank, while a portion of the liquid flows out through the outlet pipe 3. Since the outlet pipe 3 is higher than the bottom 12 of the tank, a portion of the liquid is collected at the bottom 12, i.e., accumulated liquid. During venting, the gas is discharged outside the hull by opening the vent pipe 4. When the marine low-speed diesel engine needs maintenance, the accumulated liquid in the gas-liquid separator needs to be drained, which is done by opening the drain pipe 5. The support assembly 6 is movably connected to the side wall of the tank 1. For example, this movable connection can be achieved using studs and nuts. Fixing parts are welded to the side wall of the tank 1, the studs are fixed to the support assembly 6, and the fixing parts are fixed to the studs using nuts. By turning the nuts, the position of the fixing parts is adjusted, thereby adjusting the position of the tank 1, thus achieving the movable connection between the support assembly 6 and the tank 1. The support assembly 6 is used to adjust and fix the support tank 1. When the tank 1 itself has welding errors or insufficient machining precision of parts, causing the gas-liquid separator tank 1 to tilt, the water inlet pipe 2 and water outlet pipe 3 of the gas-liquid separator tank cannot be well connected to the external pipes. The external pipes include the water inlet pipe and water outlet pipe connected to the gas-liquid separator tank in the marine low-speed diesel engine main engine system. For example, when the gas-liquid separator is fixed to the support assembly 6 due to insufficient welding precision of the fixing parts, the gas-liquid separator tilts slightly to the left, causing the inlet pipe 2 and outlet pipe 3 of the gas-liquid separator to be unable to be aligned and connected with the external pipe. If the connection precision between the inlet pipe 2 and outlet pipe 3 and the external pipe is insufficient, it may cause poor air tightness or leakage. At this time, by adjusting the support assembly 6 on the left side of the gas-liquid separator, the height of the fixing parts on the left side of the gas-liquid separator can be adjusted, so that the tank body 1 remains stable and vertical, and the inlet pipe 2 and outlet pipe 3 of the gas-liquid separator can be aligned with the external pipe, ensuring normal connection and avoiding problems such as insufficient air tightness or leakage.

[0046] The technical solution of this embodiment allows the side wall of the gas-liquid separator to be movably connected to the support assembly. By adjusting the support assembly, the height of the gas-liquid separator can be adjusted, which quickly and effectively achieves the stable arrangement of the tank. This enables the gas-liquid separator to be normally connected to external pipelines, reduces the assembly difficulty of the gas-liquid separator and the requirements for the processing and welding accuracy of the parts of the gas-liquid separator. Moreover, the structure of the gas-liquid separator and the support assembly is simple, easy to produce and assemble, and achieves efficient assembly of the gas-liquid separator.

[0047] See also Figure 1 Optionally, the tank body 1 also includes a fixing ring 13, which is evenly distributed around the outer wall of the tank body 1 and welded to the outer wall of the tank body 1 for movably connecting with the support assembly 6 to fix and support the tank body 1.

[0048] Specifically, the fixing ring 13 is welded to the side wall of the tank 1. The fixing ring 13 can be movably connected to the support assembly 6 via studs and nuts. For example, the studs are fixed to the support assembly 6, and then the fixing ring 13 is fixed to the studs via nuts. The height of the fixing ring 13 can be adjusted by turning the nuts up and down, thereby adjusting the position of the tank 1 and realizing the movable connection between the support assembly 6 and the tank 1. The number of fixing rings 13 can be set according to welding requirements. For example, there can be 3 fixing rings 13, evenly distributed around the outer side wall of the tank 1, which together with the support assembly 6 fix and support the tank 1. Since the triangular structure is relatively stable, the evenly distributed 3 fixing rings 13 can make the gas-liquid separator tank more stable.

[0049] Figure 2 This is a schematic diagram of the structure of a support assembly for a marine gas-liquid separator provided in an embodiment of the present invention. See also: Figure 1 and Figure 2 Optionally, the support assembly 6 includes: a support frame 61, an adjusting stud 62, a fastening nut 63, a first adjusting nut 64, a second adjusting nut 65, a first washer 66, and a second washer 67;

[0050] The support frame 61 and the fixing ring 13 are arranged in a one-to-one correspondence. The first end of the support frame 61 is fixed on the main unit bracket, and the second end is used to fix the tank 1.

[0051] The adjusting stud 62 is fixed to the second end of the support frame 61 by the fastening nut 63;

[0052] The first adjusting nut 64 and the first washer 66 are sequentially installed on the adjusting stud 62;

[0053] The retaining ring 13 is inserted into the adjusting stud 62, and the retaining ring 13 is located above the first washer 66;

[0054] The second washer 67 and the second adjusting nut 65 are screwed into the adjusting stud 62 in sequence, located above the retaining ring 13.

[0055] Specifically, the main engine bracket is the platform on the marine low-speed diesel engine main engine. The first end of the support frame 61 is fixed to the platform on the marine low-speed diesel engine main engine, and the second end is used to fix and support the gas-liquid separator tank. To install the support assembly 6, first install the support frame 61 on the main engine bracket, then screw the adjusting stud 62 into the second end of the support frame 61 and tighten it with the fastening nut 63; screw the first adjusting nut 64 and the first washer 66 into the adjusting stud 62, and then hoist the gas-liquid separator tank body 1 so that the three fixing rings 13 on the side wall of the tank body 1 are respectively inserted into the corresponding adjusting studs 62, and then screw in the second washer 67 and the second adjusting nut 65.

[0056] The first washer 66 and the second washer 67 are located on the upper and lower sides of the fixing ring 13, mainly to increase the contact area between the nut and the fixing ring 13, reduce pressure, prevent the nut from loosening, and protect the parts and the nut. The first adjusting nut 64 and the second adjusting nut 65 are located on the upper and lower sides of the fixing ring 13. By adjusting the first adjusting nut 64 and the second adjusting nut 65, the height of the tank 1 can be adjusted. For example, since there will inevitably be some errors in the welding of the gas-liquid separator, when the three fixing rings are not at the same height due to welding errors, the tank 1 will tilt when fixed on the support frame 61, making it impossible for the inlet pipe 2 and the outlet pipe 3 to be properly connected to the external pipe. At this time, the tank 1 can be made stable and vertical by adjusting the first adjusting nut 64 and the second adjusting nut 65 respectively, for example, by turning the nuts up or down, to ensure proper connection.

[0057] The technical solution of this embodiment allows for the movable connection between the side wall of the gas-liquid separator and the support assembly. When the gas-liquid separator tilts due to welding errors or other reasons, the height of the gas-liquid separator can be adjusted by turning the first and second adjusting nuts upwards or downwards. This quickly and effectively achieves a stable arrangement of the separator, enabling the gas-liquid separator to connect normally with external pipelines. It reduces the assembly difficulty of the gas-liquid separator and the requirements for the processing and welding accuracy of its parts. Furthermore, the structure of the gas-liquid separator and the support assembly is simple, easy to manufacture and assemble, and achieves efficient assembly of the gas-liquid separator.

[0058] Figure 3 This is a schematic diagram of another marine gas-liquid separator provided in an embodiment of the present invention. See also... Figure 3 Optionally, the vent pipe 4 includes: a first ball valve 41, an automatic vent valve 42, and a needle valve 43; the vent pipe 4 includes a main pipe and branch pipes;

[0059] The first ball valve 41 is located at one end of the main pipe near the top of the tank 11 and is used to open when discharging gas from the tank 1 so that the vent pipe 4 can be used to discharge the gas.

[0060] An automatic vent valve 42 is located at the end of the main pipe away from the top of the tank 11 to ensure gas pressure;

[0061] The needle valve 43 is installed on the branch pipe and is used to open when draining accumulated liquid so that the gas pressure inside the tank 1 is equal to that outside.

[0062] Specifically, the first ball valve 41 is located at the end of the main pipe near the top of the tank 11 and is used to control the opening and closing of the vent pipe 4. When the gas-liquid separator is working, the first ball valve 41 is opened, and the vent pipe 4 is connected to the inside of the tank, allowing the gas accumulated at the top of the tank 11 to be discharged through the vent pipe 4. During the gas discharge process, the automatic vent valve 42 automatically switches its state according to the pressure inside the tank 1. For example, when the pressure inside the tank 1 reaches the opening pressure of the automatic vent valve 42, the automatic vent valve 42 automatically opens until the pressure inside the tank 1 drops to the closing pressure of the automatic vent valve 42, at which point the automatic vent valve 42 automatically closes. By automatically opening and closing the automatic vent valve 42 according to the pressure inside the tank 1, the gas pressure inside the tank 1 can be maintained within a certain range, thereby improving drainage efficiency and allowing the liquid to be discharged smoothly. The needle valve 43 is used to open when the main unit is being repaired and the accumulated liquid needs to be discharged. After the needle valve 43 is opened, the gas pressure inside the tank 1 is equal to that outside, and the accumulated liquid at the bottom of the tank 12 is smoothly discharged by relying on atmospheric pressure.

[0063] See also Figure 3 Optionally, the drain pipe 5 includes a second ball valve 51, which is located at the end of the drain pipe 5 away from the bottom of the tank 12 and is used to open when draining the accumulated liquid in the tank body 1 so that the drain pipe 5 can be opened to drain the accumulated liquid.

[0064] Specifically, the second ball valve 51 is used to control the opening and closing of the drain pipe 5. When it is necessary to repair the main unit and drain the accumulated liquid, the second ball valve 51 and the needle valve 43 are opened, and the accumulated liquid at the bottom of the tank 12 is discharged from the tank 1 through the drain pipe 5 by relying on atmospheric pressure.

[0065] This invention also provides a ship, which includes: the marine gas-liquid separator described in any of the above embodiments. The marine gas-liquid separator can be installed in the cooling water circulation system of a marine low-speed diesel engine, fixed to the platform of the marine low-speed diesel engine through a support assembly, and connected to the pipeline in the cooling water circulation system. It is used to discharge air in the high-temperature cooling water to avoid damage to system components due to cavitation. Its technical principle and the resulting effect are similar and will not be described in detail here.

[0066] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.
