Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a natural gas compressor intake filtration device with an online replaceable filter element. Background Technology

[0002] A natural gas filter is a device used to remove solid particles, liquids, and other impurities from natural gas to ensure the purity of the gas and the normal operation of the pipeline system. The role of the natural gas filter is very important. It not only protects other equipment in the pipeline system, such as pressure reducing valves and pressure relief valves, from damage, but also ensures the quality and safe transportation of natural gas.

[0003] Currently, traditional natural gas compressor filters require shutdown for disassembly and replacement of the filter element, which affects production continuity. The filter element installed in the pipeline is inconvenient to disassemble, and the disassembly and installation time is long. It is not convenient to disassemble and install the filter element, and impurities may fall into the pipeline during the disassembly process, affecting the use of natural gas pipeline. There is an urgent need to design a natural gas compressor intake filtration device with online filter element replacement to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas compressor intake filtration device with an online filter element replacement capability, thereby addressing the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An inlet air filtration device for a natural gas compressor with replaceable filter elements includes an inlet pipe, a three-way valve assembly at one end of the inlet pipe, first connecting pipes on both sides of the three-way valve assembly, a filter pipe at one end of each of the two first connecting pipes, a second connecting pipe between the two filter pipes, an outlet pipe at the bottom of the second connecting pipe, and a one-way valve assembly between the outlet pipe and the second connecting pipe; the two filter pipes are inclined and symmetrically distributed, a filter cartridge is slidably fitted inside each filter pipe, one end of the filter cartridge is snapped into a mounting plate, and a sealing mechanism is provided between the mounting plate and the filter pipe.

[0007] Furthermore, the three-way valve assembly includes a valve body connected to the air intake pipe and the two first connecting pipes, a ball core rotatably fitted inside the valve body, a rotating rod disposed on one side of the ball core, and a rotating wheel installed on the rotating rod passing through one end of the valve body.

[0008] Furthermore, a locking block is provided on one side of the mounting plate, and a locking groove is provided at one end of the filter cartridge, with the locking block engaging with the locking groove.

[0009] Furthermore, a sealing gasket is provided at one end of the filter cartridge, and an inclined block is provided at the bottom of the inner wall of the filter cartridge. The sealing gasket corresponds to one end of the first connecting pipe, and the inclined block corresponds to one end of the second connecting pipe.

[0010] Furthermore, a sealing ring is provided between the periphery of the mounting plate and one end of the filter tube. The sealing mechanism includes two arc-shaped mounting plates disposed between the periphery of the mounting plate and one end of the filter tube. Both ends of the two arc-shaped mounting plates are provided with connecting ears, and a fixing bolt is provided between the two connecting ears.

[0011] Furthermore, the one-way valve assembly includes a solenoid valve body disposed on the second connecting pipe and two one-way valve plates rotatably fitted at the connection between the second connecting pipe and the outlet pipe, wherein the solenoid valve body cooperates with the two one-way valve plates.

[0012] In the above technical solution, the natural gas compressor intake filtration device with online filter element replacement provided by this utility model has the following advantages:

[0013] By using a three-way valve assembly and a one-way valve assembly, the flow direction of natural gas can be controlled, preventing natural gas from passing through one of the filter tubes. This allows the sealing mechanism to be disassembled and the filter cartridge inside the filter tube removed, enabling filter element replacement without shutting down the system. The inclined filter tube facilitates the disassembly and installation of the filter cartridge, which can be directly pulled out or pushed in by moving the filter tube. The inclined filter tube can also be cleaned, reducing the possibility of residual impurities affecting natural gas delivery. Attached Figure Description

[0021] like Figure 1-4 As shown in the figure, this utility model provides an air intake filtration device for a natural gas compressor with an online replaceable filter element.

[0022] The system includes an intake pipe 1, a three-way valve assembly 2 at one end of the intake pipe 1, first connecting pipes 3 on both sides of the three-way valve assembly 2, filter pipes 4 at one end of each of the two first connecting pipes 3, a second connecting pipe 5 between the two filter pipes 4, an exhaust pipe 6 at the bottom of the second connecting pipe 5, and a one-way valve assembly 7 between the exhaust pipe 6 and the second connecting pipe 5. The two filter pipes 4 are inclined and symmetrically distributed. A filter cartridge 8 is slidably fitted inside the filter pipe 4. One end of the filter cartridge 8 is snapped into a mounting plate 9. A sealing mechanism 10 is provided between the mounting plate 9 and the filter pipe 4.

[0023] Reference Figure 2 The three-way valve assembly 2 in this embodiment includes a valve body 11 connected to the inlet pipe 1 and two first connecting pipes 3, a ball core 12 rotatably fitted inside the valve body 11, a rotating rod 13 disposed on one side of the ball core 12, and a rotating wheel 14 mounted on one end of the rotating rod 13 that passes through the valve body 11. The rotating wheel 14 can be rotated to drive the rotating rod 13 to rotate, causing the rotating rod 13 to drive the ball core 12 to rotate, thus changing the direction of the natural gas.

[0024] Reference Figure 3 In this embodiment, a locking block 15 is provided on one side of the mounting plate 9, and a locking groove 16 is provided at one end of the filter cartridge 8. The locking block 15 engages with the locking groove 16. By using the locking block 15, the locking block 15 can enter the locking groove 16 for engagement, pushing the mounting plate 9 to drive the filter cartridge 8 into the filter tube 4, so that the mounting plate 9 supports the filter cartridge 8.

[0025] Reference Figure 3 In this embodiment, a sealing gasket 17 is provided at one end of the filter cartridge 8, and an inclined block 18 is provided at the bottom of the inner wall of the filter cartridge 8. The sealing gasket 17 corresponds to one end of the first connecting pipe 3, and the inclined block 18 corresponds to one end of the second connecting pipe 5. Through the provided sealing gasket 17, when the filter cartridge 8 enters the filter pipe 4, the sealing gasket 17 is made to fit against the inside of the filter pipe 4, so that the natural gas transported by the first connecting pipe 3 can directly flow towards the filter cartridge 8, and the inclined block 18 can guide the natural gas through the filter cartridge 8 to flow to the second connecting pipe 5.

[0026] Reference Figure 3 In this embodiment, a sealing ring 19 is provided between the periphery of the mounting plate 9 and one end of the filter tube 4. The sealing mechanism 10 includes two arc-shaped mounting plates 20 disposed between the periphery of the mounting plate 9 and one end of the filter tube 4. Each end of the two arc-shaped mounting plates 20 is provided with a connecting lug 21, and a fixing bolt 22 is provided between the two connecting lugs 21. After the mounting plate 9 and one end of the filter tube 4 are attached and fixed by the arc-shaped mounting plates 20, the sealing ring 19 is fitted onto the connection between the mounting plate 9 and the filter tube 4. Then, the two arc-shaped mounting plates 20 are spliced ​​together to seal and fix the connection between the mounting plate 9 and the filter tube 4. The fixing bolt 22 is used to pass through the connecting lugs 21 to fix the two arc-shaped mounting plates 20.

[0027] Reference Figure 4 In this embodiment, the one-way valve assembly 7 includes a solenoid valve body 23 mounted on the second connecting pipe 5 and two one-way valve plates 24 rotatably fitted at the connection between the second connecting pipe 5 and the gas outlet pipe 6. The solenoid valve body 23 cooperates with the two one-way valve plates 24. The solenoid valve body 23 controls the two one-way valve plates 24, regulating their opening or closing to prevent natural gas backflow or crossflow in the gas outlet pipe 6.

[0028] Working principle: During use, natural gas is supplied through the intake pipe 1 via the natural gas compressor. The natural gas passes through the three-way valve assembly 2 and is directed to the corresponding first connecting pipe 3 according to the direction of the three-way valve assembly 2. The natural gas then enters the corresponding filter pipe 4 through the first connecting pipe 3, where the filter cartridge 8 filters impurities in the natural gas. The filtered natural gas then enters the second connecting pipe 5 and is discharged through the one-way valve assembly 7 to the outlet pipe 6. When it is necessary to replace the filter cartridge 8 in the filter pipe 4, the three-way valve assembly 2 is adjusted to control the direction of natural gas supply, so that the natural gas is supplied to another first connecting pipe 3 and filtered through another filter pipe 4. Then, the sealing mechanism 10 is disassembled to remove the filter cartridge 8. During this process, the filter cartridge 8 can be tilted and gradually moved out of the filter pipe 4. The removed filter cartridge 8 is then cleaned, and the filter pipe 4 is also cleaned, allowing any remaining impurities in the filter pipe 4 to fall down along the tilted pipe. Finally, the filter cartridge 8 is reinstalled and fixed and sealed using the sealing mechanism 10.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
