Technical Field

[0001] The invention relates to the technical field of pipeline hydrate cleaning, in particular to a hydrate pipeline cleaner. Background Art

[0002] Pipeline hydrates, also known as natural gas hydrates, are ice-like crystalline substances formed by some components in natural gas and water under certain pressure and temperature conditions. It is a cage-shaped lattice inclusion complex that looks like loose ice or dense snow, with a density of about 0.88 to 0.90 g / cubic centimeter. Hydrate pipeline cleaning is a key link in maintaining the smooth flow of pipeline systems, especially in oil and gas pipeline transportation. The formation of hydrates may cause serious blockage problems.

[0003] Ordinary cleaning devices require the pipeline to be disassembled before the internal hydrates can be cleaned. For example, the existing patent document "CN219933255U A natural gas hydrate prevention and automatic cleaning device" discloses a cleaning device. The cleaning device in the above technical solution adopts a mechanical cleaning method. When cleaning, the pipeline needs to be disassembled before the internal hydrates can be cleaned, which is cumbersome to operate and inconvenient to use.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figures 1 to 6 As shown, the hydrate pipeline cleaner includes a casing structure 2, which is sleeved on the outside of the pipeline 1; a circulating heating structure 4, which is connected to the casing structure 2 and heats the pipeline 1 to remove hydrates; and an auxiliary sealing component 3, which seals and compensates the gap between the pipeline 1 and the casing structure 2.

[0027] The device can be detachably installed on the pipeline 1, and the device is fixedly arranged at the place where the long-distance pipeline is prone to compound blockage;

[0028] The sleeve structure 2 includes a connecting sleeve 201 and a sealing ring 202. The connecting sleeve 201 is sleeved outside the pipeline 1, and the sealing rings 202 are installed at both ends of the connecting sleeve 201.

[0029] In this embodiment, the auxiliary sealing assembly 3 includes a rubber sealing ring 301 and a fixed tube 302. The rubber sealing ring 301 is provided with an inner cavity and is fixedly arranged on the arc wall of the sealing ring 202. The auxiliary sealing assembly 3 further seals the gap between the pipeline 1 and the sleeve structure 2 to avoid leakage.

[0030] In this embodiment, the fixed cylinder 302 is fixedly installed on the outer wall of the connecting sleeve 201, and a movable piston 303 is slidably connected in the inner cavity of the fixed cylinder 302. One end of the fixed cylinder 302 is fixedly connected to a connecting hose 307, and the other end of the connecting hose 307 extends into the inner cavity of the rubber sealing ring 301 and is fixedly connected to the rubber sealing ring 301. One end of the movable piston 303 is connected to a rotating table 304, and the other end of the rotating table 304 is connected to a threaded rod 305. The threaded rod 305 penetrates the fixed cylinder 302, extends to the outside of the wall and is fixedly connected to the operating panel 306, and the threaded rod 305 is threadedly matched with the fixed cylinder 302.

[0031] The threaded rod 305 can be driven to rotate by manually rotating the operating disk 306, so that the movement of the threaded rod 305 can push the movable piston 303 to move, and then the gas in the inner cavity of the fixed cylinder 302 can be transported to the inner cavity of the rubber sealing ring 301 through the connecting hose 307, so that the rubber sealing ring 301 can expand. The expansion of the rubber sealing ring 301 can fully seal and compensate for the gap between the sealing ring 202 and the pipeline 1, thereby avoiding the problem of leakage of the heating medium.

[0032] In this embodiment, the circulating heating structure 4 includes a fixed bin 401, the inner cavity of the fixed bin 401 is filled with a heating medium and is equipped with a submersible pump 403 and a heater 405, the output end of the submersible pump 403 is fixedly connected to an output pipe 404, a return pipe 402 is fixedly connected to the upper wall of the inner cavity of the fixed bin 401, and the output pipe 404 and the return pipe 402 are both connected to the connecting sleeve 201. The heating medium is water or oil, and the liquid level in the fixed bin 401 does not exceed the bottom of the impurity collection tank 502. Through the operation of the heater 405, the heating medium stored in the inner cavity of the fixed bin 401 can be heated, so that through the operation of the submersible pump 403, the heating medium can be transported to the inner cavity of the connecting sleeve 201, and then refluxed to the inner cavity of the fixed bin 401 through the reflux pipe 402, thereby realizing the function of circulating flow. Through the heating function of the heating medium, the pipeline 1 at the connecting sleeve 201 can be heated, and the hydrate dissociates into water and natural gas as the temperature rises, thereby achieving the purpose of removing the hydrate.

[0033] In this embodiment, a self-filtering structure 5 is provided in the fixed bin 401, and the self-filtering structure 5 automatically filters and cleans impurities in the heating medium. The self-filtering structure 5 includes a filter mesh plate 501 installed in the fixed bin 401, an impurity collection tank 502 and a driving component. The filter mesh plate 501 is located below the reflux pipe 402, and the driving component drives the impurities on the filter mesh plate 501 to enter the impurity collection tank 502.

[0034] When the heating medium flows back into the inner cavity of the fixed bin 401 through the reflux pipe 402, the heating medium can be filtered by setting the filter screen 501, thereby avoiding the contamination of the heating medium by impurities inside the heating medium.

[0035] The driving assembly includes a first rotating shaft 506 and a second rotating shaft 509 which are rotatably connected to the inner wall of the fixed bin 401, the second rotating shaft 509 is sleeved with a water wheel 510 and is extended to the outer wall end of the fixed bin 401 and is equipped with a connecting wheel A511, the first rotating shaft 506 is sleeved with a disc 507 and is extended to the outer wall end of the fixed bin 401 and is equipped with a connecting wheel B512, and a connecting belt 513 is provided between the connecting wheel A511 and the connecting wheel B512.

[0036] In this embodiment, a connecting frame B508 is provided on the disc 507, and the other end of the connecting frame B508 is hinged to the connecting frame A505. The other end of the connecting frame A505 is connected to a movable scraper 504. The upper end of the movable scraper 504 is slidably sleeved on the outside of the guide rod 503, and the lower end is placed above the filter screen plate 501. The guide rod 503 is installed in the fixed bin 401 and is arranged parallel to the filter screen plate 501 up and down.

[0037] When the heating medium flows back to the inner cavity of the fixed bin 401 through the reflux pipe 402, the flow of the heating medium can also drive the water wheel 510 to rotate, thereby driving the second rotating shaft 509 to rotate. The rotation of the second rotating shaft 509 can drive the connecting wheel A511 to rotate. A connecting belt 513 is provided between the connecting wheel A511 and the connecting wheel B512, thereby driving the connecting wheel B512 to rotate, thereby driving the first rotating shaft 506 to rotate. The rotation of the first rotating shaft 506 can drive the disc 507 to rotate, thereby driving one end of the connecting frame B508 to move in a circular shape through the rotation of the disc 507, thereby driving the connecting frame A505 to reciprocate left and right, thereby driving the movable scraper 504 to reciprocate back and forth, thereby scraping the impurities remaining on the filter screen 501, so that the impurities fall to the impurity collection tank 502 after being scraped, thereby avoiding the phenomenon that impurities accumulate at the filter screen 501 due to long-term use and cause blockage.

[0038] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
