Description

Technical Field

[0001] This utility model relates to the field of inert gas cleaning technology, and in particular to an inert gas scrubbing tower for oil tankers. Background Technology

[0002] As is well known, in tanker operations, inert gas scrubbing towers are crucial safety equipment. They are primarily used to treat inert gases generated, such as those derived from boiler flue gas through a specific process. During operation, seawater flows counter-currently with the gas to be treated. Through spraying and adsorption, the heat in the gas is carried away, lowering its temperature. At the same time, impurities in the gas are removed, and acidic harmful gases such as sulfur dioxide are also absorbed. Only inert gases treated by the scrubbing tower meet the safety standards for transporting to areas such as cargo oil tankers on tankers.

[0003] Existing scrubbing towers do not have pre-wash functions and are made of stainless steel without an internal coating, so the cooling effect cannot be guaranteed, and high temperature alarms often occur. In addition, the scrubbing towers are easily corroded, and their service life cannot be guaranteed.

[0004] An existing patent (publication number: CN201500493U) discloses a marine inert gas system scrubbing tower, including a tower body, a central conduit connected to an external flue gas pipe in the tower body, a polypropylene demister installed on the upper outer periphery of the central conduit in the tower body, a polypropylene dehumidifier installed on the lower outer periphery of the central conduit in the tower body, and the lower end of the central conduit located below the polypropylene dehumidifier; a pre-washing device with a conical seawater nozzle at the end is installed at the point where the central conduit enters the tower body. This utility model has a reasonable structure and good working performance. By adding a pre-washing pipe inside the scrubbing tower and changing the material of the scrubbing tower by adding a coating to its inner wall, the service life of the scrubbing tower is guaranteed.

[0005] Existing patents offer solutions to the above problems, but impurities remaining in the gas can cause blockages when the gas is discharged. Due to the lack of an automatic cleaning mechanism for the internal structure, it is impossible to automatically clean and prevent blockages, which reduces the stability during gas discharge.

[0006] Therefore, an inert gas scrubbing tower for oil tankers is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an inert gas scrubbing tower for oil tankers, which can solve the problem that existing gas discharge systems suffer from blockages caused by residual impurities in the gas structure. Furthermore, the lack of an automatic cleaning mechanism for the internal structure prevents automatic cleaning and blockage prevention, thus reducing the stability of the discharged gas.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an inert gas scrubbing tower for oil tankers, comprising a transmission mechanism and a cleaning mechanism, wherein the cleaning mechanism is located inside the transmission mechanism;

[0009] The transmission mechanism includes a washing tower body, a positioning plate, guide vanes, and a guide rod. The positioning plate is fixedly connected to the top of the inner side of the washing tower body, the guide vanes are rotatably connected to the bottom of the positioning plate, and the guide rod is fixedly connected to the top of the guide vanes.

[0010] Preferably, the cleaning mechanism includes a wall cleaning component and a screen cleaning component, wherein the wall cleaning component is located on top of the washing tower body, and the screen cleaning component is located on top of the wall cleaning component.

[0011] Preferably, the wall cleaning assembly includes a flow guide hood, a transmission frame, a transverse gas spring rod, and a cleaning plate. The flow guide hood is connected to the top of the washing tower body, the transmission frame is rotatably connected to the bottom of the inner side of the flow guide hood, two transverse gas spring rods are respectively fixedly connected to both sides of the transmission frame, and the cleaning plate is fixedly connected to the output end of the transverse gas spring rod away from the transmission frame.

[0012] Preferably, the cleaning assembly includes a longitudinal gas spring rod, a cleaning scraper, and a net. The longitudinal gas spring rod is fixedly connected to the inner side of the transmission frame, the cleaning scraper is fixedly connected to the output end at the top of the longitudinal gas spring rod, and the net is fixedly connected to the top of the inner side of the diversion hood. The bottom of the net contacts the top of the cleaning scraper.

[0013] Preferably, an auxiliary bearing is engaged on the inner side of the positioning plate, and the inner side of the auxiliary bearing is rotatably connected to the surface of the guide rod.

[0014] Preferably, a protective blade is fixedly connected to the bottom of the guide blade, and the surface of the protective blade is provided with drainage patterns.

[0015] Preferably, a flow guide plate is fixedly connected to the side of the cleaning plate away from the transmission frame, and the side of the flow guide plate away from the transmission frame is in contact with the inner side of the flow hood.

[0016] Preferably, an auxiliary brush plate is fixedly connected to the top of the cleaning scraper, and the top of the auxiliary brush plate is in contact with the bottom of the interception net.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a transmission mechanism. The main body of the scrubbing tower is an existing inert gas scrubbing tower equipment. The positioning plate can support and limit the guide blades, so that the guide blades can rotate along the positioning plate with the flowing gas. When the guide blades rotate, they can drive the guide rod to rotate together, thereby providing the cleaning mechanism with the power required for self-cleaning through the guide rod. Since the power source of the guide blades is the flowing gas, there is no need to rely on power supply equipment such as electricity, which improves the flexibility of the cleaning mechanism during cleaning.

[0019] 2. This application, by setting up a cleaning mechanism, allows the wall cleaning component to cooperate with the net cleaning component. Through the transmission frame, driven by the transmission mechanism, the horizontal gas spring rod can move the cleaning plate on the inner wall of the diversion hood, which can scrape away the impurities remaining on the inner wall of the diversion hood, achieving a self-cleaning effect on the inner wall of the diversion hood. The vertical gas spring rod can rotate with the rotation of the transmission frame, driving the cleaning scraper to rotate together, thereby removing the impurities remaining at the bottom of the interception net. This achieves the effect of automatically cleaning the interception net and diversion hood when the gas flows through, improving the stability of cleaning impurities inside the interception net and diversion hood.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] An inert gas scrubbing tower for oil tankers includes a transmission mechanism 1 and a cleaning mechanism 2, wherein the cleaning mechanism 2 is located inside the transmission mechanism 1.

[0030] The transmission mechanism 1 includes a washing tower body 11, a positioning plate 12, a guide vane 13, and a guide rod 14. The positioning plate 12 is fixedly connected to the top of the inner side of the washing tower body 11, the guide vane 13 is rotatably connected to the bottom of the positioning plate 12, and the guide rod 14 is fixedly connected to the top of the guide vane 13.

[0031] In this embodiment: by setting the transmission mechanism 1, the scrubbing tower body 11 is an existing inert gas scrubbing tower device, the positioning plate 12 can support and limit the guide blade 13, so that the guide blade 13 can rotate along the positioning plate 12 with the flowing gas. When the guide blade 13 rotates, it can drive the guide rod 14 to rotate together, so that the guide rod 14 provides the power required for self-cleaning to the cleaning mechanism 2. Since the power source of the guide blade 13 is the flowing gas, there is no need to rely on power supply equipment such as power supply, which improves the flexibility of the cleaning mechanism 2 during cleaning.

[0032] Specifically, such as Figure 4 As shown, the cleaning mechanism 2 includes a wall cleaning component 21 and a screen cleaning component 22. The wall cleaning component 21 is located on the top of the washing tower body 11, and the screen cleaning component 22 is located on the top of the wall cleaning component 21.

[0033] Specifically, such as Figure 5 As shown, the wall cleaning assembly 21 includes a flow guide hood 211, a transmission frame 212, a transverse gas spring rod 213, and a cleaning plate 214. The flow guide hood 211 is connected to the top of the washing tower body 11. The transmission frame 212 is rotatably connected to the bottom of the inner side of the flow guide hood 211. Two transverse gas spring rods 213 are respectively fixedly connected to both sides of the transmission frame 212. The cleaning plate 214 is fixedly connected to the output end of the transverse gas spring rod 213 on the side away from the transmission frame 212.

[0034] Specifically, such as Figure 6As shown, the cleaning assembly 22 includes a longitudinal gas spring rod 221, a cleaning scraper 222, and an intercepting net 223. The longitudinal gas spring rod 221 is fixedly connected to the inner side of the transmission frame 212. The cleaning scraper 222 is fixedly connected to the output end of the top of the longitudinal gas spring rod 221. The intercepting net 223 is fixedly connected to the top of the inner side of the diversion hood 211. The bottom of the intercepting net 223 contacts the top of the cleaning scraper 222.

[0035] In this embodiment: by setting the cleaning mechanism 2, the wall cleaning component 21 can cooperate with the net cleaning component 22. With the transmission mechanism 1, the transmission frame 212 can drive the transverse gas spring rod 213 to move the cleaning plate 214 on the inner wall of the diversion hood 211, which can scrape off the impurities remaining on the inner wall of the diversion hood 211, achieving the effect of self-cleaning the inner wall of the diversion hood 211. The longitudinal gas spring rod 221 can drive the cleaning scraper 222 to rotate together with the rotation of the transmission frame 212, thereby removing the impurities remaining at the bottom of the interception net 223. Thus, the interception net 223 and the diversion hood 211 are automatically cleaned when the gas flows through, improving the stability of cleaning impurities in the interception net 223 and the diversion hood 211.

[0036] Specifically, such as Figure 3 As shown, an auxiliary bearing 15 is snapped into the inner side of the positioning plate 12, and the inner side of the auxiliary bearing 15 is rotatably connected to the surface of the guide rod 14.

[0037] Specifically, such as Figure 3 As shown, a protective blade 16 is fixedly connected to the bottom of the guide blade 13, and the surface of the protective blade 16 is provided with drainage patterns.

[0038] In this embodiment: by setting an auxiliary bearing 15 and a protective blade 16, the auxiliary bearing 15 provides auxiliary guidance between the guide rod 14 and the positioning plate 12, which can further increase the stability of the guide rod 14 when rotating within the positioning plate 12 and improve the efficiency of the guide rod 14 in providing kinetic energy to the cleaning mechanism 2. The protective blade 16 can protect the bottom of the guide blade 13 and block impurities in the gas from bottom to top, avoiding damage to the guide blade 13 and extending the service life of the guide blade 13.

[0039] Specifically, such as Figure 5 As shown, a flow guide plate 215 is fixedly connected to the side of the cleaning plate 214 away from the transmission frame 212, and the side of the flow guide plate 215 away from the transmission frame 212 contacts the inner side of the flow hood 211.

[0040] Specifically, such as Figure 6 As shown, an auxiliary brush plate 224 is fixedly connected to the top of the cleaning scraper 222, and the top of the auxiliary brush plate 224 is in contact with the bottom of the interception net 223.

[0041] In this embodiment: by setting a flow guide plate 215 and an auxiliary brush plate 224, the flow guide plate 215 cleans the inner wall of the flow hood 211 along with the cleaning plate 214. The flow guide plate 215 can further increase the contact range between the cleaning plate 214 and the inner wall of the flow hood 211, thereby improving the stability of cleaning the inner wall of the flow hood 211. The auxiliary brush plate 224 contacts the bottom of the interception net 223 along with the cleaning scraper 222, thereby further increasing the contact range with the bottom of the interception net 223, thereby improving the stability and efficiency of cleaning the bottom of the interception net 223.

[0042] Working principle: First, an inert gas conveying device is connected to the scrubbing tower body 11. When the inert gas is conveyed from bottom to top through the bottom of the scrubbing tower body 11, impurities in the inert gas will gradually remain in the scrubbing tower body 11 over time. At this time, the guide vane 13 will rotate on the positioning plate 12 along with the guide rotating rod 14 as the gas flows. The guide rotating rod 14 will drive the transmission frame 212 to rotate together. When the transmission frame 212 rotates, it will drive the horizontal gas spring rod 213 and the vertical gas spring rod 221 to rotate respectively. When the horizontal gas spring rod 213 rotates, it will drive the cleaning plate 214 to move in a circle along the inner wall of the diversion hood 211, and scrape off the impurities on the inner wall of the diversion hood 211 while moving. When the vertical gas spring rod 221 rotates, it will drive the cleaning scraper 222 to move in a circle along the bottom of the interception net 223, and scrape off the impurities at the bottom of the interception net 223 while moving.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
