Description

Technical Field

[0001] This utility model relates to the field of natural gas distribution technology, and in particular to a gas pipeline connection device. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas from extraction sites or processing plants to urban gas distribution centers or industrial users; they are also called gas transmission pipelines. Natural gas is primarily used as fuel and can be used to manufacture carbon black, chemicals, and liquefied petroleum gas (LPG). Natural gas connection devices are an indispensable part of pipelines used to connect the transported gas, monitor the natural gas flow rate, and remove impurities from the gas to prevent it from mixing with impurities in the pipeline during transport, which could affect the purity of the natural gas and cause blockages in the pipeline and at the outlet. Currently, most connection devices simply use a filter plate, which has unsatisfactory filtration effects. Furthermore, impurities tend to accumulate at the inlet of the filter plate, leading to a significant pressure difference and increasing the frequency of filter plate replacement, thus increasing filtration costs. Utility Model Content

[0003] Therefore, it is necessary to provide a gas pipeline connection device to address the above problems.

[0004] A gas pipeline connection device includes a main body, an inlet pipe, an outlet pipe, an impurity recovery component, and a filter cartridge. The main body is hollow. The inlet pipe is installed on one side of the main body, and the outlet pipe is installed on the upper end of the main body, communicating with the inlet pipe through the main body. A positioning ring is provided on the inner wall of the upper end of the main body around the outlet of the outlet pipe. The impurity recovery component is detachably installed on the lower end of the main body and communicates with the main body. A boss is provided inside the impurity recovery component. The filter cartridge is vertically installed inside the main body. The upper end of the filter cartridge is movably connected to the positioning ring, and the lower end of the filter cartridge is movably connected to the boss. The intake air from the inlet pipe causes the filter cartridge to rotate within the main body.

[0005] Preferably, the outer circumferential surface of the filter cylinder is provided with spiral blades.

[0006] Preferably, the air outlet pipe is a corrugated pipe.

[0007] Preferably, the central axis of the filter cartridge is offset from the central axis of the air inlet pipe.

[0008] Preferably, an intake valve is installed on the intake pipe.

[0009] The lower end of the impurity recovery component is conical, and a drain valve is provided at the lower end of the impurity recovery component.

[0010] The advantages of this invention are: it integrates a rotatable filter cartridge to filter impurities in natural gas. The rotation of the filter cartridge ensures that the impurities are evenly distributed on the surface of the filter cartridge, preventing the accumulation of impurities on the side facing the air inlet pipe, which would cause a sudden increase in pressure difference. This dynamically slows down the clogging rate of the filter element, extends the service life of the filter element, and reduces its operating costs. Attached Figure Description

[0015] like Figures 1-2As shown, a gas pipeline connection device includes a main body 1, an inlet pipe 2, an outlet pipe 3, an impurity recovery component 4, and a filter cylinder 5. The main body 1 is hollow. The inlet pipe 2 is installed on one side of the main body 1, and the outlet pipe 3 is installed on the upper end of the main body 1. The outlet pipe 3 is connected to the inlet pipe 2 through the main body 1. A positioning ring 11 is provided on the inner wall of the upper end of the main body 1 around the outlet pipe 3. The impurity recovery component 4 is detachably installed on the lower end of the main body 1 and is connected to the main body 1. A boss 41 is provided inside the impurity recovery component 4. The filter cylinder 5 is vertically installed inside the main body 1. The upper end of the filter cylinder 5 is movably connected to the positioning ring 11, and the lower end of the filter cylinder 5 is movably connected to the boss 41. A rotating vane 51 is provided on the outer circumferential surface of the filter cylinder 5. The air intake of the inlet pipe 2 drives the filter cylinder 5 to rotate inside the main body 1. Specifically, in this embodiment, the main body 1 is a hollow, cylindrical tube connected to the inlet pipe 2 and the outlet pipe 3. The inlet pipe 2 is installed on the side of the main body 1, allowing air to enter horizontally. The outlet pipe 3 is installed at the upper end of the main body 1, offset from the inlet direction of the inlet pipe 2, to facilitate the natural gas passing through the filter cartridge 5 within the main body 1 before being completely filtered. The filter cartridge 5 is installed vertically within the main body 1. After the natural gas enters the main body 1 through the inlet pipe 2, it passes through the filter cartridge 5, thus achieving filtration. Under pressure, the filtered natural gas flows upward along the filter cartridge 5 and enters the outlet pipe 3 for discharge. To install the filter cartridge 5, a positioning ring 11 is provided on the upper inner wall of the main body 1. The diameter of the positioning ring 11 is slightly larger than the diameter of the outlet pipe 3. At the lower end of the main body 1, it is detachably connected to the impurity recovery component 4 via a threaded structure. A rubber sealing ring is provided at the connection to enhance the sealing performance of the connection. The main body 1 is connected to the impurity recovery component 4. A boss 41 is provided inside the impurity recovery component 4, located directly below the positioning ring 11. The filter cartridge 5 is installed in conjunction with the positioning ring 11. To allow the filter cartridge 5 to rotate, sealed bearings are integrally installed on the inner walls of both the upper and lower ends of the filter cartridge 5, facilitating simultaneous disassembly and cleaning during replacement. The sealed bearings are fitted onto the outer sides of the positioning ring 11 and the boss 41, allowing the filter cartridge 5 to rotate freely. The filter cartridge 5 in this design is made of glass fiber, capable of intercepting micron-sized particles (e.g., 5~100μm), suitable for high purity requirements, and resistant to acids and alkalis, preventing any reaction with components in natural gas. The high porosity of the entire filter cartridge reduces the pressure difference between the inner and outer sides of the filter cartridge 5 and the resistance to natural gas flow.The filter cartridge 5 is installed vertically, with a gap between its outer circumference and the inner wall of the main body 1. After the air inlet pipe 2 is connected, natural gas enters the main body 1 and passes through the filter cartridge 5. Impurities carried in the natural gas are filtered out by the filter cartridge 5. To prevent impurities from accumulating on the side of the filter cartridge 5 facing the air inlet pipe 2, which could lead to an unbalanced pressure difference, the filter cartridge 5 is designed to be rotatable. When the filter cartridge 5 rotates, impurities on its surface are easily flung off by centrifugal force, dynamically slowing down the clogging rate of the filter cartridge 5, reducing the frequency of cleaning, and lowering its operating costs. The flung-off impurities fall and collect in the impurity recovery unit 4 for easy collection and centralized processing at a specific time. When the filter cartridge 5 rotates, the side of the filter cartridge 5 facing the air inlet pipe 2 is always dynamic, making the impurities covering the outer circumference of the filter cartridge 5 more uniform and preventing impurities on the filter cartridge 5 from accumulating on the side facing the air inlet pipe 2.

[0016] like Figure 2 As shown, the outer circumferential surface of the filter cylinder 5 is provided with spiral blades 51. The spiral structure of the spiral blades 51 can decompose the airflow along the axial direction to form a continuous thrust component, reduce turbulence and separation phenomena, thereby reducing the rotational resistance of the filter cylinder.

[0017] Specifically, the gas outlet pipe 3 is a corrugated pipe, which makes the gas outlet pipe 3 expandable within a certain range, facilitating the connection between the gas outlet pipe 3 and the gas outlet pipeline, overcoming a certain degree of angular offset, and reducing the impact of the vibration of the gas inlet pipe 2 and the natural gas compressor on the downstream gas outlet pipeline.

[0018] Specifically, the central axis 5 of the filter cartridge is offset from the central axis of the air inlet pipe 2, so that the natural gas entering the main body 1 from the air inlet pipe 2 does not directly face the front of the filter cartridge 5, but faces the side of the circumferential surface of the filter cartridge 5. The filter cartridge 5 is subjected to uneven thrust from the natural gas, making it easier to rotate in the main body 1, shaking off the impurities filtered on the surface and reducing the clogging rate of the filter cartridge 5.

[0019] like Figures 1-2 As shown, an intake valve 21 is installed on the intake pipe 2. Users can control and adjust the downstream gas volume and gas flow rate through the intake valve 21. At the same time, when the intake valve 21 is fully closed, it is convenient to maintain the natural gas pipeline in sections.

[0020] like Figures 1-2 As shown, the lower end of the impurity recovery component 4 is cone-shaped. Impurities gather to the lowest point of the cone under their own gravity. A drain valve 42 is provided at the lower end of the impurity recovery component 4. When maintenance personnel open the drain valve 42, the impurities accumulated in the impurity recovery component 4 can be discharged without disassembling the impurity recovery component 4, making sewage discharge more convenient.

[0021] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
