Description

Technical Field

[0001] The utility model relates to the technical field of natural gas filtering equipment, in particular to a filtering equipment for removing tiny particles in natural gas. Background Technique

[0002] As a clean energy source, natural gas is increasingly widely used in people's production and life. After being mined, natural gas needs to be processed through procedures such as filtration and compression before it can be used. Among them, the filtration step removes impurities such as moisture and dust particles carried in natural gas to avoid damage to subsequent equipment such as compressors; Patent No. CN201920787932.3 discloses a natural gas filtering equipment. By setting a spiral filtering cylinder and a diversion cylinder, it is convenient to install an extended filter screen in the filter, and combined with the first filtering layer, the filter element and the extended filtering layer, it can be applicable to natural gas with different filtering requirements; However, when using the filter element to filter particulate matter in natural gas, and when the impurities in the filter element accumulate to a certain extent, only the whole filter can be disassembled to disassemble and replace the filter element, and the operation is not convenient enough. For this reason, we propose a filtering equipment for removing tiny particles in natural gas. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a filtering equipment for removing tiny particles in natural gas.

[0004] The technical solution adopted by the utility model to solve its technical problems is a filtering equipment for removing tiny particles in natural gas, including a filter main body. An air inlet hole and an air outlet hole are arranged on the outer wall surface of the filter main body, and a conical hole communicating with the air inlet hole is opened in the filter main body. A spiral groove is opened on the inner wall surface of the conical hole;

[0005] A ring hole is opened on the inner wall surface of the filter main body, and a disc cover for sealing is screwed and installed on the outer wall surface of the filter main body. A ring frame that fits with the ring hole is assembled at one end of the disc cover located inside the filter main body, and a filter element layer for filtering tiny particles of natural gas is assembled in the ring frame. A hexagon is integrally formed on the side of the disc cover away from the filter main body.

[0006] By adopting the above technical solution, when using the filtering equipment to filter tiny particles in natural gas, natural gas can conveniently pass through the air inlet hole and enter the conical hole. It is convenient for natural gas to generate a rotational centrifugal force between the conical hole and the spiral groove on its surface, so that the tiny particles in natural gas can be thrown flying on the inner wall of the conical hole under the action of the centrifugal force, and conveniently fall to the surface of the disc cover along the inner wall of the conical hole. At the same time, the filter element layer on the surface of the ring frame can continue to filter natural gas, and the two cooperate with each other to facilitate improving the filtering effect on tiny particles in natural gas. Subsequently, the natural gas after double filtration can conveniently be discharged from the air outlet hole;

[0007] When the tiny particles intercepted and filtered inside the filter body accumulate to a certain extent, the natural gas pipeline valve at the position connecting the air outlet and the air inlet of the filter body can be closed, and then the hexagonal body at the bottom of the disc cover is directly rotated by a wrench, so that the disc cover and the filter body are screwed and separated from each other. Subsequently, the disc cover is directly pulled, so that the disc cover drives the ring frame to be separated from the ring hole between the ring frame and the filter body. Subsequently, the filter element layer inside the ring frame can be replaced, and the impurities accumulated on the surface of the disc cover can be cleaned. Moreover, when disassembling, installing and replacing, it is not necessary to disassemble the filter body, and the operation is more convenient.

[0008] Specifically, a cross ring is installed inside the disc cover in a screwed manner, and a vertical pipe is assembled on the side of the cross ring away from the disc cover. A shock-absorbing cylinder is assembled inside the vertical pipe, and an oval body corresponding to the conical hole is assembled at one end of the shock-absorbing cylinder away from the vertical pipe. A sliding pipe that fits with the vertical pipe is assembled on the side of the oval body close to the disc cover.

[0009] By adopting the above technical solution, when natural gas impacts the disc cover through the conical hole, the shock-absorbing cylinder in the vertical hole on the surface of the cross ring at the top of the disc cover facilitates elastic support for the oval body, so that the oval body can buffer and split the air flow. At the same time, the sliding pipe at the bottom of the oval body is slidably connected with the vertical pipe, so that the oval body can operate more stably.

[0010] Specifically, a spring located on the outer periphery of the shock-absorbing cylinder is assembled between the sliding pipe and the vertical pipe.

[0011] By adopting the above technical solution, the spring facilitates cooperation with the shock-absorbing cylinder to work, so that the buffering performance of the oval body is improved.

[0012] Specifically, a vertical hole for sewage discharge is opened between the disc cover and the hexagonal body, and a plug for blocking is installed inside the vertical hole in a screwed manner.

[0013] By adopting the above technical solution, when the filter element layer does not need to be replaced, the plug in the vertical hole can be directly unscrewed, so that the impurities accumulated on the surface of the disc cover can be discharged.

[0014] Specifically, a circular groove that fits with the disc cover is opened on the side of the filter body close to the disc cover, and rubber gaskets are bonded to both the inner side of the circular groove and the ring hole.

[0015] By adopting the above technical solution, the circular groove on the outer wall surface of the filter body facilitates mutual fit with the protrusions on the surface of the disc cover, which is convenient for improving the tightness when the disc cover is screwed and installed on the outer wall surface of the filter body, and is convenient for reducing the occurrence of leakage. At the same time, the rubber gaskets are respectively located in the circular groove and the ring hole, which is convenient for improving the tightness after the connection between the disc cover and the filter body and between the ring frame and the ring hole.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. Through the design of the air inlet hole, air outlet hole, conical hole and spiral groove, when the filtering device is used to filter the tiny particles in natural gas, the natural gas can conveniently pass through the air inlet hole and enter the conical hole. The natural gas can conveniently generate a rotational centrifugal force between the conical hole and the spiral groove on its surface, so that the tiny particles in the natural gas can be thrown and fly onto the inner wall of the conical hole under the action of the centrifugal force, and conveniently fall along the inner wall of the conical hole to the surface of the disc cover. At the same time, the filter element layer on the surface of the ring frame can continue to filter the natural gas. The two cooperate with each other to facilitate improving the filtering effect of the tiny particles in the natural gas. Subsequently, the natural gas after double filtration can conveniently be discharged from the air outlet hole.

[0018] 2. Through the design of the ring hole, ring frame, disc cover, filter element layer and hexagon body, when the tiny particles intercepted and filtered inside the filter body accumulate to a certain extent, the natural gas pipeline valve at the position connecting the air outlet hole and the air inlet hole of the filter body can be closed, and then the hexagon body at the bottom of the disc cover can be directly rotated by using a wrench, so that the disc cover and the filter body are screwed and separated from each other. Subsequently, the disc cover is directly pulled, so that the disc cover drives the ring frame to be separated from the ring hole between the disc cover and the filter body. Subsequently, the filter element layer inside the ring frame can be replaced, and the impurities accumulated on the surface of the disc cover can be cleaned. Moreover, when disassembling, assembling and replacing, the filter body does not need to be disassembled, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figures 1-3 , an embodiment of the present utility model provides a technical solution: a filtering device for removing fine particles in natural gas, including a filter body 1. An air inlet hole 2 and an air outlet hole 3 are provided on the outer wall surface of the filter body 1, and a conical hole 4 communicating with the air inlet hole 2 is opened in the filter body 1. A spiral groove 5 is provided on the inner wall surface of the conical hole 4; a ring hole 6 is provided on the inner wall surface of the filter body 1, and a disk cover 7 for plugging is screwed and installed on the outer wall surface of the filter body 1. A ring frame 8 fitted with the ring hole 6 is assembled at one end of the disk cover 7 located inside the filter body 1, and a filter element layer 9 for filtering fine particles in natural gas is assembled in the ring frame 8. A hexagonal body 10 is integrally formed on the side of the disk cover 7 away from the filter body 1.

[0026] During use, when using the filtering device to filter fine particles in natural gas, natural gas can conveniently pass through the air inlet hole 2 and enter the conical hole 4. Natural gas can conveniently generate a rotational centrifugal force between the conical hole 4 and the spiral groove 5 on its surface, so that the fine particles in the natural gas can be thrown flying onto the inner wall of the conical hole 4 under the action of the centrifugal force and conveniently fall along the inner wall of the conical hole 4 to the surface of the disk cover 7. At the same time, the filter element layer 9 on the surface of the ring frame 8 can continue to filter the natural gas. The two cooperate with each other to facilitate improving the filtering effect of fine particles in natural gas. Subsequently, the natural gas after double filtration can conveniently be discharged from the air outlet hole 3;

[0027] When the fine particles filtered and intercepted inside the filter body 1 accumulate to a certain extent, the natural gas pipeline valve at the position connecting the air outlet hole 3 and the air inlet hole 2 of the filter body 1 can be closed, and then the hexagonal body 10 at the bottom of the disk cover 7 can be directly rotated by using a wrench, so that the disk cover 7 and the filter body 1 are screwed and separated from each other. Subsequently, the disk cover 7 is directly pulled, so that the disk cover 7 drives the ring frame 8 to be separated from the ring hole 6 of the filter body 1. Subsequently, the filter element layer 9 inside the ring frame 8 can be replaced, and the impurities accumulated on the surface of the disk cover 7 can be cleaned. Moreover, when disassembling, installing and replacing, it is not necessary to disassemble the filter body 1, and the operation is more convenient.

[0028] As Figure 2 and Figure 3 shown, a cross ring 11 is screwed and installed in the disk cover 7, and a vertical pipe 12 is assembled on the side of the cross ring 11 away from the disk cover 7. A shock-absorbing cylinder 13 is assembled in the vertical pipe 12, and an oval body 14 corresponding to the conical hole 4 is assembled at one end of the shock-absorbing cylinder 13 away from the vertical pipe 12. A sliding pipe 15 fitted with the vertical pipe 12 is assembled on the side of the oval body 14 close to the disk cover 7.

[0029] During use, when natural gas passes through the conical hole 4 and impacts the disc cover 7, the shock absorber cylinder 13 in the vertical hole 17 on the surface of the cross ring 11 at the top of the disc cover 7 facilitates elastic support for the oblate body 14, enabling the oblate body 14 to buffer and divert the airflow. At the same time, the sliding tube 15 at the bottom of the oblate body 14 is slidably connected to the vertical tube 12, allowing the oblate body 14 to operate more stably.

[0030] As Figure 2 and Figure 3 shown, a spring 16 is assembled between the sliding tube 15 and the vertical tube 12 and is located outside the shock absorber cylinder 13.

[0031] During use, the spring 16 facilitates cooperation with the shock absorber cylinder 13 to work, improving the buffering performance of the oblate body 14.

[0032] As Figure 2 and Figure 3 shown, a vertical hole 17 for sewage discharge is provided between the disc cover 7 and the hexagonal body 10, and a plug 18 for blocking is screwed and installed in the vertical hole 17.

[0033] During use, when the filter element layer 9 does not need to be replaced, the plug 18 in the vertical hole 17 can be directly unscrewed, and then the impurities accumulated on the surface of the disc cover 7 can be discharged.

[0034] As Figure 2 shown, a circular groove 19 that fits the disc cover 7 is provided on one side of the filter body 1 close to the disc cover 7, and rubber pads 20 are bonded to both the inner side of the circular groove 19 and the ring hole 6.

[0035] During use, the circular groove 19 on the outer wall surface of the filter body 1 facilitates mutual fitting with the protrusions on the surface of the disc cover 7, improving the tightness when the disc cover 7 is screwed and installed on the outer wall surface of the filter body 1, reducing the occurrence of leakage. At the same time, the rubber pads 20 are respectively located in the circular groove 19 and the ring hole 6, improving the tightness after connection between the disc cover 7 and the filter body 1 and between the ring frame 8 and the ring hole 6.

[0036] Working principle and usage process of the utility model: During use, first install the corresponding structural components in appropriate positions. When using the filtering device to filter the tiny particles in natural gas, the natural gas conveniently passes through the air inlet hole 2 and enters the conical hole 4. The natural gas conveniently generates a rotational centrifugal force between the conical hole 4 and the spiral groove 5 on its surface, enabling the tiny particles in the natural gas to be thrown away onto the inner wall of the conical hole 4 under the action of the centrifugal force and conveniently falling along the inner wall of the conical hole 4 to the surface of the disc cover 7. At the same time, the filter element layer 9 on the surface of the ring frame 8 can continue to filter the natural gas. The two cooperate with each other to facilitate improving the filtering effect of the tiny particles in the natural gas. Subsequently, the natural gas after double filtration conveniently discharges from the air outlet hole 3. And when the tiny particles intercepted and filtered inside the filter body 1 accumulate to a certain extent, the natural gas pipeline valve at the position connecting the air outlet hole 3 and the air inlet hole 2 of the filter body 1 can be closed. Then directly rotate the hexagonal body 10 at the bottom of the disc cover 7 with a wrench, so that the disc cover 7 and the filter body 1 are screwed and separated from each other. Subsequently, directly pull the disc cover 7, so that the disc cover 7 drives the ring frame 8 to be separated from the annular hole 6 between the disc cover 7 and the filter body 1. Subsequently, the filter element layer 9 inside the ring frame 8 can be replaced, and the impurities accumulated on the surface of the disc cover 7 can be cleaned. And when disassembling, installing and replacing, it is not necessary to disassemble the filter body 1, and the operation is more convenient.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above-described embodiments and descriptions in the specification are only illustrative of the principles of the utility model.
