Description

Technical Field

[0001] This utility model relates to the field of oil and gas field gas production technology, specifically to a device for cleaning accumulated dirt in vent pipes. Background Technology

[0002] In the production process of oil and gas well stations, storage tanks are tank devices used to temporarily store the produced mixed liquids. Since the mixed liquids contain a lot of flammable gases and volatile organic compounds, in order to avoid environmental pollution and safety accidents caused by overpressure in the storage tanks, existing storage tanks are generally connected to vent pipes through pipes equipped with flame arresters, and the gas is centrally discharged and treated through the vent pipes.

[0003] like Figure 1 As shown, the existing vent pipe 2 has a vertical pipe section 21 at its end. An inclined pipe section 22 is connected to the side of the vertical pipe section 21 closest to the ground. The flame arrester 3 is installed on the horizontal pipe section 23 in front of the inclined pipe section 22. During production, it was found that when the liquid level in the storage tank 10 is too high, the gas volume is large when the drain valve is draining, or the outlet temperature is high, the oil and water in the mixture enter the horizontal pipe section 23 with the gas, condense to form oil and water, contaminate the flame arrester 3, and spread to the vent pipe 2 through the flame arrester 3. After a certain period of time, the horizontal pipe section 23 of the vent pipe 2 becomes full of oil. When the oil and gas well station needs to perform gas venting, the oil accumulated in the vent pipe 2 is sprayed out with the gas, causing environmental pollution. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the easy accumulation of dirt in the vent pipes of existing oil and gas well stations, which makes them difficult to clean and causes environmental pollution when gas is released.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0024] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0026] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0027] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0028] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0029] Example 1 like Figures 2-6As shown, a vent pipe sludge cleaning device includes an adapter 1, a sludge collection tank 5, and an air supply mechanism 7. The adapter 1 is provided with a connecting plate 11 that is bolted to the flange on the vent pipe 2 for connecting the flame arrester 3. The adapter 1 is detachably connected to a guide pipe 4, which can communicate with the sludge collection tank 5. The air supply mechanism 7 can communicate with the vent pipe 2 between the liquid storage tank 10 and the flame arrester 3.

[0030] like Figure 2 , Figure 4 As shown, adapter 1 is used to connect the flange at the position of flame arrester 3 on vent pipe 2 to the sludge cleaning device. In use, the flame arrester 3 on the horizontal pipe section 23 of vent pipe 2 is removed and adapter 1 is connected to connect the sludge cleaning device.

[0031] In an optional embodiment, the adapter 1 may include a first connector 12 and a second connector 13. The first connector 12 and the second connector 13 are the two ends of a quick connector that are mated together. The first connector 12 is bolted to the flange after the flame arrester 3 has been removed via the connecting plate 11. The second connector 13 is detachably connected to the guide pipe 4, so that the first connector 12 is bolted to the horizontal pipe section 23 of the vent pipe 2 after the flame arrester 3 has been removed, and the second connector 13 is connected to the guide pipe 4. The first connector 12 and the second connector 13 are quickly assembled when cleaning accumulated dirt.

[0032] In optional implementations, such as Figure 4 As shown, the adapter 1 may also include a bend section 14. One end of the bend section 14 is provided with a connecting plate 11 for bolting to the flange on the vent pipe 2 after the flame arrester 3 has been removed, and the other end is detachably connected to the first connector 12. The bend section 14 serves as a transition structure between the vent pipe 2 and the sludge cleaning device. It can be adapted to use when the length of the quick connector is too long to meet the installation and connection of the first connector 12 and the second connector 13 in the space formed after the flame arrester 3 has been removed, so as to meet the smooth installation of the sludge cleaning device in the space after the flame arrester 3 has been removed on the vent pipe 2 of different specifications and models.

[0033] The guide pipe 4 is a pipe structure that connects the adapter 1 and the sludge collection tank 5. The guide pipe 4 is used to realize the communication between the adapter 1 and the sludge collection tank 5. The sludge collection tank 5 can be a tank structure that is formed by excavating the ground and is treated with anti-corrosion and waterproofing. The sludge collection tank 5 is used to collect the sludge washed out from the discharge pipe 2.

[0034] In an optional embodiment, the guide pipe 4 includes a PVC steel wire hose. The PVC steel wire hose guide pipe 4 has strong corrosion resistance, which can meet the usage environment in the oil and gas production field, and has a certain degree of transparency, which allows operators to easily observe the cleaning status of accumulated dirt and facilitates the control of the dirt cleaning process.

[0035] In optional implementations, such as Figure 3As shown, a lifting ring 42 can be installed on the guide pipe 4. The lifting ring 42 is installed at the end of the guide pipe 4 away from the vent pipe 2 or multiple rings are distributed longitudinally along the guide pipe 4 to facilitate the movement of the guide pipe 4 by pulling it, and to facilitate the adjustment of the position of the guide pipe 4 according to the on-site usage environment. The structure is simple.

[0036] In one or more embodiments, the sludge collection tank 5 can be a tank structure with an open top, and the sludge washed out of the discharge pipe 2 can be collected by extending the guide pipe 4 into the sludge collection tank 5.

[0037] In an optional embodiment, a cover plate 6 can be installed on top of the sludge collection tank 5 to seal the sludge collection tank 5, preventing the sludge from splashing under the action of airflow and ensuring the smooth and safe reception of the sludge. The cover plate 6 can be pressed onto the guide pipe 4, such as... Figure 5 As shown, a limiting hole 61 adapted to the guide pipe 4 can also be provided on the cover plate 6, so that the guide pipe 4 can be extended into the tank body through the limiting hole 61, so as to ensure that the relative position of the guide pipe 4 and the sludge collection tank 5 is stable and facilitates the collection of sludge.

[0038] In an optional embodiment, the side of the cover plate 6 closest to the sludge collection tank 5 can be entirely covered with a plastic sheet to prevent dirt from splashing onto the cover plate 6 and remaining there, so that the dirt can be collected smoothly in the sludge collection tank 5 for subsequent unified treatment.

[0039] In one or more implementations, such as Figure 3 As shown, a limiting member 41 can be provided at the end of the guide pipe 4. The limiting member 41 can be matched with the limiting hole 61 for limiting. The size of the limiting member 41 is larger than that of the limiting hole 61, so that after the guide pipe 4 passes through the limiting hole 61, the relative position of the guide pipe 4 and the cover plate 6 can be limited by the limiting member 41, so as to prevent the guide pipe 4 from falling out of the sludge collection tank 5 under the impact reaction force of airflow and dirt.

[0040] In an optional embodiment, the limiting member 41 may be two wing plates disposed in the radial direction at the end of the guide pipe 4, the two wing plates being connected to the clamp and being clamped and connected to the guide pipe 4 by the clamp.

[0041] In one or more implementations, such as Figure 5 As shown, an isolation element 62 can be installed inside the limiting hole 61. The isolation element 62 has a cut 63. The isolation element 62 is used to temporarily seal the limiting hole 61, reduce the overflow of gas released from the sludge in the sludge collection tank 5, and improve the environmental quality and safety of the oil and gas well station site.

[0042] In an optional embodiment, the isolation member 62 may be a silicone plate-shaped structure connected to the cover plate 6, the limiting hole 61 may be a round hole, and the cut 63 may be a cross-shaped slit set in the center of the isolation member 62, so that the end of the guide tube 4 can push against the isolation member 62 and pass through the limiting hole 61 from the cut 63 position.

[0043] In an optional embodiment, the cover plate 6 is connected to the sludge collection tank 5 by a locking 9 to ensure that the cover plate 6 and the sludge collection tank 5 are connected together, the structure is stable, and the sludge collection tank 5 is kept closed when idle to reduce the escape of gases released from the sludge.

[0044] The air supply mechanism 7 is used to introduce airflow into the vent pipe 2 to blow and push the dirt when the dirt cleaning device is in use, so that the dirt in the vent pipe 2 can be cleaned by the power provided by the airflow.

[0045] In optional implementations, such as Figure 6 As shown, the gas supply mechanism 7 may include a separator 71, which is connected to the gas production mechanism 72. The gas production mechanism 72 is an existing oil and gas well station device used to collect mixed liquids within the formation. The gas production mechanism 72 may be a gas production tree. The separator 71 is an existing oil and gas well station device used to collect the produced mixed liquids and perform three-phase separation. In existing oil and gas well stations, the separator 71 is generally connected to the storage tank 10 and the vent pipe 2 through a pipeline system. The storage tank 10 is then connected to the vent pipe 2 through the pipeline system to ensure the safe production of the oil and gas well station. In this embodiment, the separator 71 is connected to the vent pipe 2 through a connecting pipe 8. A vent valve 81 is installed on the connecting pipe 8. This can be based on the existing oil and gas well station pipeline system or it can be a separately added pipeline structure to provide power for cleaning the accumulated dirt in the vent pipe 2 through gas production from the gas well. No additional power mechanism is needed to adapt to the safe production of the oil and gas well station.

[0046] This embodiment of a vent pipe sludge cleaning device uses an adapter 1 that can be bolted to the flange of the vent pipe 2 used for connecting the flame arrester 3. When sludge cleaning of the vent pipe 2 is required, the flame arrester 3 is removed, the adapter 1 is connected, and gas is supplied into the vent pipe 2 through the gas supply mechanism 7 to purge the sludge in the vent pipe 2. The sludge in the vent pipe 2 is then transported to the sludge collection tank 5 along the guide pipe 4. This effectively reduces the amount of oil sprayed from the vent pipe 2, preventing oil pollution caused by the output of oil from the vent pipe 2. The device has a simple structure and can be easily combined with existing vent pipes 2. It can conveniently clean the sludge in the vent pipe 2, improve the cleaning effect and efficiency, and reduce the cleaning cost.

[0047] The above description is only a preferred embodiment of the present utility model and is 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.
