Description

Technical Field

[0001] This utility model relates to the field of connecting pipe structure technology, and in particular to a connecting pipe for a ship carbon capture device with a leak-proof sealing mechanism. Background Technology

[0002] Ship carbon capture systems are one of the key technologies for achieving green emission reduction in the shipping industry. These systems capture carbon dioxide (CO2) from the exhaust gases emitted by the ship's main engine and auxiliary engines through methods such as chemical adsorption, membrane separation, or cryogenic liquefaction. The connecting pipes, acting as the "blood vessels" of the system connecting various core units (such as absorption towers, regeneration towers, compression modules, and storage tanks), are responsible for transporting media such as high-temperature, high-pressure flue gas, corrosive absorbent solutions, and liquid CO2. Their sealing reliability directly affects the system's operational safety, carbon capture efficiency, and marine environmental safety.

[0003] Currently, the most common pipe connection method in marine carbon capture systems is still the flange, bolt, and gasket sealing structure. This structure has the following inherent defects: During ship navigation, continuous rolling, trimming, and vibration impacts cause the bolt preload to loosen to a certain extent, and the inner end face of the flange to undergo slight displacement, causing the traditional flat gasket or rubber O-ring seal to fail, thus affecting the pipe connection seal. Therefore, a marine carbon capture system connection pipe with a leak-proof sealing mechanism is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connecting pipe for a ship carbon capture device with a leak-proof sealing mechanism includes a pipe fitting connected between two flange interfaces. The pipe fitting includes a guide pipe, both ends of which are connected to flanges. The flanges are fixed to the flange interfaces by a number of bolts. An annular groove is formed between the flanges and the flange interfaces, and a sealing gasket is embedded in the annular groove. An anti-detachment component is fitted on the outside of the flanges and the flange interfaces.

[0007] Preferably, the flange interface and the inner wall of the flange annular groove are provided with multiple annular protrusions of different inner diameters, and the annular protrusions are embedded in the surface of the sealing gasket through the annular groove. The annular protrusions in the annular groove can support the sealing gasket, effectively preventing the sealing gasket from easily loosening and shifting, and to a certain extent preventing the sealing gasket from deforming.

[0008] Preferably, both ends of the inner wall of the guide tube are connected to an inner liner tube, and the inner liner tube is inserted into the flange interface. The surface of the inner liner tube is fitted with a sealing ring through an annular groove. The sealing ring design on the outer side of the inner liner tube can fill the gap between the inner liner tube and the inner wall of the flange interface, thereby ensuring the sealing performance of the flange and the flange interface.

[0009] Preferably, the sealing ring has an arc structure on both sides, and the inner wall of the inner liner tube has inclined surfaces at both ends. The arc structure design on both sides of the sealing ring can facilitate the movement of the inner liner tube when it is under pressure.

[0010] Preferably, a T-shaped ring is provided at the center of the inner wall of the inner liner tube annular groove, and the T-shaped ring is embedded inside the sealing ring. When the sealing ring is installed in the annular groove of the inner liner tube, the T-shaped ring can be embedded in the inner wall of the sealing ring, thereby fixing the sealing ring.

[0011] Preferably, the anti-detachment component includes two opposing anti-detachment covers, which are fastened to the flange interface and the outside of the flange. One side of each anti-detachment cover has a slot that matches the end of the bolt shaft. A handle is connected to the outside of each anti-detachment cover. The slot on the side of the anti-detachment cover can be snapped onto the surface of the bolt shaft, so that the inner end of the anti-detachment cover abuts against the side end face of the nut, thereby locking and positioning the nut.

[0012] Preferably, the two opposing anti-slip caps are connected and fixed together by a number of elastic rubber strips. The inner wall of the anti-slip cap is provided with an inner gasket, and the inner gasket abuts against the surface of the bolt nut. The two anti-slip caps can be joined together by the elastic rubber strips. The elastic rubber strips have an elastic telescopic structure, which makes it convenient for the staff to hold and pull outwards, control the movement of the two handles, and facilitate the adjustment of the anti-slip caps.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting anti-detachment components, the flange interface and flange plate mating bolts are matched and limited. Compared with the traditional structure, this device uses two opposing anti-detachment covers to be installed on the outside of the flange interface and flange plate, so that one side of the anti-detachment cover abuts against the nut. The anti-detachment cover end is slotted and snaps onto the bolt shaft end surface, thereby reducing the probability of the nut loosening. This reduces the probability of the nut preload loosening to a certain extent due to continuous rolling, pitching, and vibration impacts during ship navigation, and thus prevents the occurrence of micro-displacement of the inner end face of the flange plate.

[0015] 2. By setting up pipe fittings, the sealing performance of the flange and flange interface is ensured. Compared with the traditional structure, this device sets an inner liner at the port of the guide pipe, inserts the inner liner into the flange interface, and sets a sealing ring on the surface of the inner liner to increase the sealing performance. At the same time, annular grooves are opened on the flange interface and the inner side of the flange, and multiple annular protrusions with internal strength are set in the annular grooves to limit and support the sealing gasket, effectively reducing the probability of deformation of the sealing gasket, thereby ensuring the sealing effect.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4A connecting pipe for a ship carbon capture device with a leak-proof sealing mechanism includes a pipe fitting 2 connected between two flange interfaces 1. The pipe fitting 2 includes a guide pipe 21, and flanges 22 are connected to both ends of the guide pipe 21. The flanges 22 are fixed to the flange interfaces 1 by several bolts. An annular groove is provided between the flanges 22 and the flange interfaces 1, and a sealing gasket 25 is embedded in the annular groove. Anti-detachment components 3 are sleeved on the outside of the flanges 22 and the flange interfaces 1.

[0024] The flange interface 1 and the inner wall of the flange 22 are provided with multiple annular protrusions of different inner diameters, and the annular protrusions are embedded in the surface of the sealing gasket 25 through the annular groove.

[0025] Both ends of the inner wall of the guide tube 21 are connected to the inner liner tube 23, and the inner liner tube 23 is inserted into the flange interface 1. The surface of the inner liner tube 23 is fitted with a sealing ring 24 through an annular groove.

[0026] The sealing ring 24 has a rounded structure on both sides, and the inner wall of the inner liner tube 23 has inclined surfaces at both ends.

[0027] A T-shaped ring is provided at the center of the inner wall of the lining tube 23, and the T-shaped ring is embedded inside the sealing ring 24.

[0028] The anti-detachment component 3 includes two opposing anti-detachment covers 31. The two anti-detachment covers 31 are fastened to the outside of the flange interface 1 and the flange 22. A slot adapted to the end of the bolt shaft is opened on one side of the anti-detachment cover 31. A handle 33 is connected to the outside of the anti-detachment cover 31.

[0029] The two opposing anti-detachment covers 31 are connected and fixed together by several elastic rubber strips 32. An inner gasket 34 is provided on the inner wall of the anti-detachment cover 31, and the inner gasket 34 abuts against and adheres to the surface of the bolt nut.

[0030] When the sealing gasket 25 is embedded in the annular groove of the flange interface 1 and the flange 22, the annular protrusion in the annular groove can support the sealing gasket 25, effectively preventing the sealing gasket 25 from easily loosening and shifting, and to a certain extent preventing the sealing gasket 25 from deforming, thus ensuring the sealing effect between the flange interface 1 and the flange 22. When the flange 22 is mated with the flange interface 1, the inner liner tube 23 on the left side of the flange 22 can be inserted into the flange interface 1. The sealing ring 24 on the outside of the inner liner tube 23 is designed to fill the gap between the inner liner tube 23 and the inner wall of the flange interface 1, thereby ensuring the sealing performance of the flange 22 and the flange interface 1.

[0031] The arc-shaped structure design on both sides of the sealing ring 24 allows the inner liner tube 23 to move easily under pressure. At the same time, the inclined design on both ends of the inner liner tube 23 reduces the chance of carbon capture leakage. When the sealing ring 24 is installed in the annular groove of the inner liner tube 23, the T-shaped ring can be embedded in the inner wall of the sealing ring 24, thereby fixing the sealing ring 24 and effectively preventing the sealing ring 24 from loosening or shifting during the insertion of the inner liner tube 23.

[0032] When the anti-disengagement cover 31 is fastened to the flange interface 1 and the flange 22, the slot on the side of the anti-disengagement cover 31 can be snapped onto the bolt shaft end surface, so that the inner end of the anti-disengagement cover 31 abuts against the side end face of the nut, thereby locking and positioning the nut. The two anti-disengagement covers 31 can be connected by the elastic rubber strip 32. The elastic rubber strip 32 has an elastic telescopic structure, which makes it convenient for the operator to hold the handle 33 and pull it outward, control the movement of the two handles 33, and facilitate the adjustment of the anti-disengagement cover 31. Through the design of the inner gasket 34 on the inner wall of the anti-disengagement cover 31, the inner gasket 34 can fit against the nut surface of the bolt, effectively preventing the nut from rotating and loosening.

[0033] Working principle: According to the appendix Figure 2 With appendix Figure 3 As shown, during the docking process between flange interface 1 and flange 22, guide tube 21 approaches flange interface 1, allowing inner liner tube 23 to be inserted into flange interface 1. During the insertion process, sealing ring 24 can be compressed and adhered to the inner wall of flange interface 1. Before inserting inner liner tube 23, sealing gasket 25 is placed in the annular groove of flange 22 or flange interface 1. When flange 22 and flange interface 1 are docked, sealing gasket 25 can be fitted between the annular groove of flange 22 and flange interface 1. The skirt side of sealing gasket 25 is extended and can be placed on the inner wall of flange 22 and flange interface 1 to expand the sealing area.

[0034] Secondly, before flange interface 1 is connected to pipe fitting 2, anti-detachment component 3 is fitted onto the surface of guide pipe 21. After flange interface 1 and flange 22 are fixed by several sets of bolts, according to the attached... Figure 3 As shown, pull the handles 33 on both sides outward to move the anti-detachment cover 31, thereby stretching the two elastic rubber strips 32. When the handles 33 move to the surface of the flange interface 1 and the flange 22, the anti-detachment cover 31 is pushed manually by the rebound force of the elastic rubber strips 32 to control the anti-detachment cover 31 to cover the surface of the flange interface 1 and the flange 22 and cover the bolt. The side groove of the anti-detachment cover 31 is fitted to the bolt shaft end, so that the inner side of the anti-detachment cover 31 is fitted to the nut surface, thereby limiting the tightened nut. The size of the anti-detachment cover 31 is customized, and the internal spacing of the anti-detachment cover 31 is adapted to the length of the bolt fixing position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
