Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation technology, specifically to a filter used for oil-gas separation. Background Technology

[0002] In various fields such as petrochemicals, natural gas extraction, and industrial manufacturing, the separation and treatment of oil-gas mixtures is a crucial step in ensuring production safety and improving resource utilization. Direct emission of oil-containing gases into downstream equipment not only wastes oil resources but may also cause equipment corrosion and pipeline blockages. Therefore, specialized oil-gas separation equipment is needed to purify the mixture and achieve efficient separation and recovery of gas and oil. The oil-gas separators commonly used in the industry mainly intercept oil droplets through internal filter elements, and complete the separation process by combining gravity sedimentation and fiber adsorption principles. When it is working, oily gas enters the filter housing and flows through the filter elements. The oil droplets are intercepted and collected by the filter media and then drip to the bottom of the housing under the action of gravity. The separated pure gas is discharged through the outlet, thus achieving the initial separation of oil and gas. Existing oil-gas separator filters have certain limitations in practical applications: the compatibility between the filter element and the equipment installation structure is poor, and they can often only be matched with a single specification of filter element, making it impossible to use different models of filter elements, resulting in insufficient flexibility. To address this, we propose a filter for oil-gas separation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a filter for oil-gas separation. By using the elastic fit between the conical surface of the conical ring and the rubber sleeve, it can flexibly adapt to filter barrels of various diameters while ensuring the sealing between the filter barrel and the installation structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a filter for oil-gas separation, comprising a filter housing, wherein a top cover is threadedly connected to the upper end of the filter housing, and an adapter component; The adapter component includes a round opening, a rubber sleeve, a conical ring, and a mounting cavity. The mounting cavities are respectively opened at the left and right ends of the top cover. The upper and lower inner walls of the mounting cavity are provided with round openings. The rubber sleeve is fixedly connected between two adjacent round openings. The interior of each mounting cavity is provided with a conical ring. The conical ring is fitted onto the middle of the outer arc surface of the rubber sleeve located inside the same mounting cavity. The upper ends of the two round openings on the upper side are fixedly connected to pipes. The system also includes filter barrels, which are respectively disposed inside the filter housing. The upper end of the filter housing is located inside the adjacent rubber sleeve on the upper side. Through the elastic fit between the conical surface of the conical ring and the rubber sleeve, flexible adaptation to filter barrels of various diameters can be achieved while ensuring the sealing between the filter barrel and the installation structure.

[0005] Furthermore, the adapter component also includes guide rods and guide slides. The guide rods are respectively disposed between the upper and lower inner walls of the two mounting cavities, and the guide slides are all opened at the rear end of the conical ring. The guide slides are all slidably connected to the guide rods located inside the same mounting cavity, providing stable sliding guidance for the conical ring.

[0006] Furthermore, the adapter component also includes a screw and a threaded hole. The screw is threadedly connected to the front side between the upper and lower inner walls of the two mounting cavities, and the threaded hole is opened at the front end of the tapered ring. The threaded hole is threadedly connected to the screw located inside the same mounting cavity to drive the tapered ring to move.

[0007] Furthermore, the adapter component also includes tightening screws, which are threaded to the left and right ends of the top cover respectively. The ends of the two tightening screws near the center of the top cover are used to engage with the lower end of the adjacent inner rubber sleeve to tighten the filter barrel.

[0008] Furthermore, a conical funnel is installed at the lower end of the interior of the filter housing, with the lower end of the conical funnel penetrating the lower side wall of the filter housing to facilitate the discharge of oil.

[0009] Furthermore, a manual valve is connected in series at the lower end of the conical funnel to discharge oil.

[0010] Furthermore, an observation window is provided at the front end of the outer arc of the filter housing to facilitate observation of whether the filter canister is clogged and needs to be replaced.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This filter for oil-gas separation has the following advantages: The adapter component uses the conical surface of the conical ring and the elastic fit of the rubber sleeve to both allow the conical ring to move and compress the rubber sleeve to cause elastic deformation, thus tightly fitting the upper end of filter barrels of different diameters and achieving flexible adaptation to filter barrels of various specifications. At the same time, it can also enhance the sealing performance between the filter barrel and the installation structure by utilizing the sealing properties of the rubber sleeve and the compressive force of the conical ring, effectively preventing oil and gas leakage at the connection and ensuring the stability and efficiency of the oil and gas separation process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a filter for oil-gas separation, including a filter housing 1, with mounting brackets on both the left and right sides of the outer arc surface of the filter housing 1, a top cover 3 threadedly connected to the upper end of the filter housing 1, a rubber sealing gasket on the upper end surface of the filter housing 1, and the top wall of the top cover 3 in contact with the rubber sealing gasket, and also includes an adapter component 2. Adapter component 2: It includes a round opening 21, a rubber sleeve 22, a conical ring 24 and a mounting cavity 27. The mounting cavities 27 are respectively opened at the left and right ends of the top cover 3. The upper and lower inner walls of the mounting cavity 27 are provided with round openings 21. The rubber sleeve 22 is fixedly connected between two adjacent round openings 21. The interior of the mounting cavity 27 is provided with a conical ring 24. The conical ring 24 is fitted onto the middle of the outer arc surface of the rubber sleeve 22 located inside the same mounting cavity 27. The upper ends of the two round openings 21 on the upper side are fixedly connected with pipes 6. The adapter component 2 also includes a tightening screw 26, which is threaded to the left and right ends of the top cover 3 respectively. The ends of the two tightening screws 26 near the center of the top cover 3 are used to cooperate with the lower end of the adjacent inner rubber sleeve 22. The adapter component 2 also includes a guide rod 23 and a guide slide 28. The guide rod 23 is respectively disposed between the upper and lower inner walls of the two mounting cavities 27. The guide slide 28 is opened at the rear end of the conical ring 24. The guide slide 28 is slidably connected to the guide rod 23 located inside the same mounting cavity 27. The adapter component 2 also includes screws 25 and threaded holes 29. The screws 25 are threadedly connected to the front sides of the upper and lower inner walls of the two mounting cavities 27, respectively. The threaded holes 29 are all opened at the front end of the conical rings 24 and are threadedly connected to the screws 25 located inside the same mounting cavity 27. Corrugated tubes are provided between the upper and lower sides of the front end of the two conical rings 24 and the upper and lower inner walls of the same mounting cavity 27. The screws 25 are all located inside the adjacent corrugated tubes. The corrugated tubes provide external support for the screws 25 and ensure the sealing and lubrication of the screws 25. The upper side of the top cover 3 is rotatably connected to a knob. The central axis of the knob is fixedly connected to the center of the upper end face of the adjacent screw 25. First, unscrew the top cover 3. The worker, wearing gloves, holds the filter bucket 8 and loosens the tightening screw 2. 6. Remove the filter canister 8 and replace it with a new one. Insert the new filter canister 8 back into the rubber sleeve 22, and then tighten the tightening screw 26. The tightening screw 26 contacts the adjacent rubber sleeve 22 and tightens the upper end of the filter canister 8. At this time, the filter canister 8 is tightened by the tightening screw 26 into the lower round opening 21. Then rotate the knob on the upper side of the top cover 3 to drive the screw 25 to rotate. The screw 25 drives the conical ring 24 to move downward along the guide rod 23 through the threaded engagement with the threaded hole 29 at the front end of the conical ring 24. When the conical ring 24 moves, its conical surface presses the middle part of the outer arc surface of the rubber sleeve 22, causing the rubber sleeve 22 to undergo elastic deformation and tightly fit the upper end of the filter canister 8. Then screw the top cover back onto the filter housing 1, and it can participate in the oil-gas separation work again. The system also includes filter barrels 8, which are respectively installed inside the filter housing 1. The upper end of the filter housing 1 is located inside the adjacent rubber sleeve 22 on the upper side. The filter housing 1 is installed on the frame of the place of use through two mounting brackets. After that, the external gas supply pipe is connected to the left pipe 6 through the flange, and the right pipe 6 serves as the exhaust pipe. The oily gas is transported to the left round opening 21 of the top cover 3 through the left pipe 6, passes through the rubber sleeve 22 and enters the filter housing 1 through the left filter barrel 8. When the oily gas flows through the filter barrel 8, it passes through the filter material inside the filter barrel 8, such as glass fiber, to achieve oil-gas separation. Large-diameter oil droplets are directly intercepted by the filter material and detach from the surface of the filter material under the action of gravity. When small-diameter oil droplets pass through the gaps between the filter material fibers, they collide with the fibers due to the diffusion effect and gradually aggregate to form large oil droplets. Then, they flow downward along the surface of the filter material. The pure gas after separation passes through the right filter barrel 8, flows upward to the round opening 21 on the right side of the top cover 3, and is discharged through the right rubber sleeve 22 and the right pipe 6, and enters the subsequent gas use system. A conical funnel 4 is installed at the lower end of the filter housing 1. The lower end of the conical funnel 4 penetrates the lower side wall of the filter housing 1. A manual valve 5 is connected in series at the lower end of the conical funnel 4. The operating handwheel of the manual valve 5 penetrates the front end of the filter housing 1. The filtered oil flows down the inner wall of the filter housing 1 and eventually flows into the conical funnel 4 at the lower end of the filter housing 1. The conical structure of the conical funnel 4 uses gravity to guide the oil to concentrate towards the center, avoiding oil residue at the bottom of the filter housing 1. After a period of time, the operating handwheel of the manual valve 5 is manually rotated to open the manual valve 5. The oil in the conical funnel 4 is discharged through the lower outlet, realizing oil recovery or centralized treatment. An observation window 7 is provided at the front end of the outer arc of the filter housing 1, through which the two filter canisters 8 can be observed. If the filter canister 8 is found to be clogged, the filter should be stopped and the filter canister 8 should be replaced.

[0016] The working principle of the oil-gas separation filter provided by this utility model is as follows: The filter housing 1 is installed on the frame at the place of use through two mounting brackets. Then, the external gas supply pipe is connected to the left pipe 6 through a flange, and the right pipe 6 serves as the exhaust pipe. Oily gas is transported through the left pipe 6 to the left round opening 21 of the top cover 3, passes through the rubber sleeve 22 and enters the filter housing 1 through the left filter barrel 8. When the oily gas flows through the filter barrel 8, it passes through the filter material inside the filter barrel 8, such as glass fiber, to achieve oil-gas separation. Large-diameter oil droplets are directly intercepted by the filter material and desorbed under the action of gravity. As small-diameter oil droplets pass through the gaps between the filter media fibers, they gradually coalesce into larger droplets due to diffusion and collision with the fibers. These droplets then flow downwards along the filter media surface. The purified gas, after separation, passes through the right-side filter barrel 8 and flows upwards to the round opening 21 on the right side of the top cover 3. It then exits through the right-side rubber sleeve 22 and the right-side pipe 6, entering the subsequent gas consumption system. The filtered oil flows downwards along the inner wall of the filter housing 1, eventually converging into the conical funnel 4 at the lower end of the filter housing 1. The conical structure of the funnel 4 utilizes gravity to guide the oil towards the center, preventing oil residue at the bottom of the filter housing 1. After a period of time, manually rotate the operating handwheel of manual valve 5 to open it. The oil in the conical funnel 4 will be discharged through the lower outlet, achieving oil recovery or centralized treatment. During this process, observe the two filter canisters 8 through the observation window 7. If filter canister 8 is found to be clogged, the filter needs to be stopped and the filter canister 8 replaced. First, unscrew the top cover 3. The worker, wearing gloves, holds the filter canister 8 and loosens the tightening screw 26 to remove the filter canister 8. Replace it with a new filter canister 8, reinsert the new filter canister 8 into the rubber sleeve 22, and then tighten the tightening screw 26. The tightening screw 26 contacts the adjacent rubber sleeve 22 and tightens the upper end of the filter barrel 8. At this time, the filter barrel 8 is tightened by the tightening screw 26 inside the lower round opening 21. Then, rotate the knob on the upper side of the top cover 3 to drive the screw 25 to rotate. The screw 25 drives the conical ring 24 to move downward along the guide rod 23 through the threaded engagement with the threaded hole 29 at the front end of the conical ring 24. When the conical ring 24 moves, its conical surface presses the middle part of the outer arc surface of the rubber sleeve 22, causing the rubber sleeve 22 to undergo elastic deformation and tightly fit the upper end of the filter barrel 8. Then, screw the top cover back onto the filter shell 1, and it can participate in the oil-gas separation work again.
