Description

Technical Field

[0001] The invention belongs to the technical field of oil mist emission and separation, and in particular relates to an oil mist emission and separation device. Background Art

[0002] In industrial production, many industries such as petrochemicals and mechanical processing have oil and gas production links. Based on environmental protection requirements and the safety of equipment operation, it is necessary to effectively discharge and separate the generated oil mist. At present, there are many oil mist emission and separation devices on the market, which can initially treat oil mist to a certain extent.

[0003] However, there are still many problems to be solved in the existing oil mist discharge and separation devices. In terms of oil collection, during the oil and gas separation operation, oil is often stored at the bottom of the oil receiving tank. Due to the flow of the oil body, this part of the stored oil generally does not cause the oil to adhere to the bottom of the tank, but the oil remaining at the high position at the bottom of the oil receiving tank is difficult to remove. Due to the limitations of the design and actual operation of the oil receiving funnel tank, conventional means are difficult to reach the high-level area for treatment, causing this part of the oil to adhere and accumulate for a long time and be difficult to clean.

[0004] From the perspective of equipment maintenance, the existing oil mist discharge tank cannot be cleaned regularly. As the service time increases, impurities in the oil mist continue to accumulate in the tank, which may clog the pipes in the tank, affect the normal operation of the equipment, and reduce the oil mist discharge separation efficiency.

[0005] For the core component of the oil mist discharge separation device, the filter packing, it is difficult to ensure the ventilation state during long-term filtering operation. In actual operation, oil droplets are easy to adhere to the surface of the filter packing. If not handled in time, the oil will gradually accumulate on the filter packing plate, hindering the passage of gas, reducing the filtering effect, and thus affecting the equipment's ability to continuously handle the oil-gas mixture.

[0006] More importantly, when unstable oil and gas enter the oil mist discharge tank, the existing device cannot effectively deal with it. When the oil and gas pressure is unstable, the excessive pressure will continuously and unevenly impact the tank wall of the oil mist discharge tank. Under such harsh working conditions for a long time, the tank wall is prone to fatigue damage, deformation and even rupture, which greatly shortens the service life of the oil mist discharge tank.

[0007] In summary, it is of great practical significance and urgent need to develop an oil mist discharge separation device that can effectively remove residual oil at high positions in the oil receiving funnel tank, achieve regular impurity removal in the oil mist discharge tank, ensure long-term ventilation of the filter packing, and adapt to unstable oil and gas pressure. Summary of the invention

[0008] Objective of the Invention: In view of the deficiencies of the prior art, the present invention provides an oil mist emission separation device, which solves the problems that it is difficult to remove the high-level oil in the bottom of the oil collecting funnel tank during oil collection in the existing oil mist emission separation device, the oil mist emission tank cannot be regularly cleaned of impurities, it is difficult to ensure the long-term ventilation state of the filter packing, and the tank wall is easily damaged due to the inability to effectively cope with the impact of unstable oil and gas pressure.

[0009] An oil mist emission separation device, comprising a climbing platform and an oil mist emission tank. There is a notch on the climbing platform, an exhaust pipe is arranged at the top of the oil mist emission tank, an intake pipe is arranged on the side of the oil mist emission tank, and legs are arranged at the bottom of the oil mist emission tank. It is characterized in that: an oil collecting funnel tank is arranged inside the oil mist emission tank, a rubber ring is sleeved on the oil collecting funnel tank, a telescopic pipe is arranged inside the oil collecting funnel tank, a rubber sleeve is arranged on the telescopic pipe, and friction lines are arranged on the rubber sleeve. A porous oil outlet plate is arranged between the bottom of the telescopic pipe and the oil collecting funnel tank. The oil collecting funnel tank is attached to the inner wall of the oil mist emission tank, and the oil collecting funnel tank and the telescopic pipe move together. A first spring is sleeved on the telescopic pipe extending outside the oil collecting funnel tank. A limiting plate is arranged at the top of the telescopic pipe. The first spring is limited by the limiting plate. A spring groove is arranged at the top of the oil mist emission tank. The bottom of the first spring is limited by the spring groove. A rotating disk is arranged at the top of the limiting plate. A filter packing disk mechanism is arranged inside the oil mist emission tank. The filter packing disk mechanism vibrates when the telescopic pipe moves, ensuring that oil droplets can quickly drip from the filter packing disk mechanism and ensuring that gas can be discharged from the filter packing disk mechanism. The intake pipe is arranged between the filter packing disk mechanism and the oil collecting funnel tank.

[0010] The filter packing disk mechanism includes a packing ring, a second spring and a strip-shaped elastic sheet. The packing ring is connected to the inner top of the oil mist emission tank through a group of second springs. The telescopic pipe passes through the packing ring and slides in the packing ring. A group of strip-shaped elastic sheets are symmetrically arranged at the bottom of the packing ring. The strip-shaped elastic sheets are in contact with and abut against the rubber sleeve. Rubber foot sleeves are arranged at the ends of the strip-shaped elastic sheets abutting against the rubber sleeve to facilitate increasing the friction force.

[0011] Further, the diameter of the packing ring is 6 cm - 10 cm smaller than the diameter of the top of the oil mist emission tank to ensure the vibration space.

[0012] Further, the strip-shaped elastic sheet is made of stainless steel.

[0013] Further, the strip-shaped elastic sheet is arranged at the bottom of the packing ring through bolts.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] Dynamic vibration oil cleaning: During the intake process, due to the unstable rate of oil and gas discharge, the oil receiving funnel tank and the telescopic pipe move simultaneously. Through the linkage of the telescopic pipe and spring 1, the strip-shaped elastic piece on the packing ring contacts the rubber sleeve on the telescopic pipe, causing the packing ring to vibrate, promoting the rapid detachment of oil droplets from the packing surface, actively removing the accumulated oil on the packing ring through the vibration mechanism, and ensuring the gas flow efficiency.

[0016] Self-cleaning oil receiving structure: When the oil mist discharge tank stops intake and spring 1 is fully extended, the oil receiving funnel tank will rise and fit against the inner wall of the oil mist discharge tank, scraping the oil on the tank wall of the oil mist discharge tank. During this process, the upward movement of the oil receiving funnel tank drives the strip-shaped elastic piece to rub and vibrate with the rubber sleeve, thereby removing the excess oil droplets on the packing ring. These oil droplets then flow out from the porous oil outlet plate. After spring 1 is fully extended and plays a supporting role for the telescopic pipe and the oil receiving funnel tank, it is convenient for the operator to rotate the rotating disk to make the oil receiving funnel tank rotate. The strip-shaped elastic piece can remove the oil remaining at the high position of the oil receiving funnel tank, and finally discharge the oil from the porous oil outlet plate. The oil receiving funnel tank fits against the inner wall of the tank body, directly collecting the oil droplets on the tank wall and avoiding oil stain residue. Brief Description of the Drawings

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In one embodiment, Figures 1 to 8 As shown, an oil mist discharge separation device comprises a climbing platform 1 and an oil mist discharge tank 2. A notch 11 is arranged on the climbing platform 1 to facilitate manual operation of the climbing platform 1 to rotate the rotating disk 61. An exhaust pipe 21 is arranged on the top of the oil mist discharge tank 2 to discharge the filtered exhaust gas. An intake pipe 22 is arranged on the side of the oil mist discharge tank 2 to allow the oil and gas mixture to enter. A support leg 23 is arranged at the bottom of the oil mist discharge tank 2. The characteristics are as follows: an oil receiving funnel tank 3 is arranged inside the oil mist discharge tank 2, and a rubber ring 31 is sleeved on the oil receiving funnel tank 3 to receive the oil. The funnel tank 3 is used to receive the dripping oil drops, which flow out from the porous oil outlet plate 9. A telescopic tube 4 is arranged inside the oil receiving funnel tank 3, and a rubber sleeve 5 is arranged on the telescopic tube 4. The rubber sleeve 5 is provided with friction lines, and the rubber sleeve 5 has a certain friction ability. A porous oil outlet plate 9 is arranged between the bottom of the telescopic tube 4 and the oil receiving funnel tank 3 for discharging oil and slag. The oil receiving funnel tank 3 is fitted with the inner wall of the oil mist discharge tank 2, and the oil receiving funnel tank 3 moves with the telescopic tube 4. When no oil or gas enters, the spring 51 is fully extended to support the telescopic tube 4 and the oil receiving funnel tank 3, and the extension A spring 51 is sleeved on the telescopic tube 4 outside the oil receiving funnel tank 3, a limit plate 6 is set on the top of the telescopic tube 4, and the spring 51 is limited by the limit plate 6. A spring groove 7 is set on the top of the oil mist discharge tank 2, and the bottom of the spring 51 is limited by the spring groove 7. A rotating disk 61 is set on the top of the limit plate 6. The spring 51 is fully extended to support the telescopic tube 4 and the oil receiving funnel tank 3, which is convenient for the rotation of the rotating disk 61. A filter packing disk mechanism 8 is set inside the oil mist discharge tank 2. The filter packing disk mechanism has the function of oil and gas separation. The structure 8 vibrates when the telescopic tube 4 moves. Through the linkage between the telescopic tube 4 and the spring 51, the strip spring piece 83 on the packing ring contacts the rubber sleeve 5 on the telescopic tube 4, causing the packing ring 81 to vibrate, prompting the oil droplets to quickly break away from the packing surface, ensuring that the oil droplets can quickly drip from the filter packing plate mechanism 8 and that the gas can be discharged from the filter packing plate mechanism 8. The air inlet pipe 22 is arranged between the filter packing plate mechanism 8 and the oil receiving funnel tank 3, and can be located between the filter packing plate mechanism 8 and the oil receiving funnel tank 3 when the oil and gas are rushed in.

[0028] In one embodiment, referring to Figure 4 , the filter packing disc mechanism 8 includes a packing ring 81, a second spring 82, and a strip-shaped elastic piece 83. The packing ring 81 is connected to the top inside the oil mist discharge tank 2 through a set of second springs 82. The telescopic pipe 4 passes through the packing ring 81 and the telescopic pipe 4 slides in the packing ring 81. A set of strip-shaped elastic pieces 83 are symmetrically arranged at the bottom of the packing ring 81. The strip-shaped elastic pieces 83 are in contact with and abutted against the rubber sleeve 5. A rubber foot sleeve 89 is provided at one end of the strip-shaped elastic piece 83 that abuts against the rubber sleeve 5.

[0029] In one embodiment, referring to Figure 4 , the diameter of the packing ring 81 is 6 - 10 cm smaller than the diameter of the top of the oil mist discharge tank 2.

[0030] In one embodiment, referring to Figure 4 , the material of the strip-shaped elastic piece 83 is stainless steel.

[0031] In one embodiment, referring to Figure 4 , the strip-shaped elastic piece 83 is arranged at the bottom of the packing ring 81 through bolts 84.

[0032] In one embodiment, as Figures 1 to 8 shown, the production inlet oil and gas state: The porous oil outlet plate 9 is connected to an external hose. The oil and gas enter the oil mist discharge tank 2 from the inlet pipe 22. Since the oil and gas enter the oil mist discharge tank 2 and the oil receiving funnel tank 3 moves downward to make room for the oil and gas, this movable setting enables the oil receiving funnel tank 3 to be used in scenarios where the oil and gas pressure is unstable, effectively reducing the pressure exerted by the oil and gas on the oil mist discharge tank 2. The surface of the rubber sleeve 5 is provided with friction lines and has friction ability. When the inlet oil and gas is unstable, the telescopic pipe 4 will make telescopic movements inside the oil mist discharge tank 2. At this time, the strip-shaped elastic piece 83 on the packing ring 81 comes into contact with the rubber sleeve 5 on the telescopic pipe 4, causing the packing ring 81 to vibrate. This vibration prompts the oil droplets to quickly detach from the packing surface, ensuring that the oil droplets can quickly drip from the packing ring 81, and at the same time, the gas can be discharged from the packing ring 81, thereby ensuring that the packing ring 81 has the ability to conduct air for a long time.

[0033] In one embodiment, as Figures 1 to 8As shown in the figure, the process of accumulated oil cleaning: when the oil mist discharge tank 2 stops admitting air, the first spring 51 will fully extend, providing support for the telescopic pipe 4 and the oil receiving funnel tank 3. At the same time, the oil receiving funnel tank 3 will rise in contact with the inner wall of the oil mist discharge tank 2, scraping the oil on the tank wall of the oil mist discharge tank 2. During this process, the upward movement of the oil receiving funnel tank 3 drives the strip-shaped elastic piece 83 to frictionally vibrate with the rubber sleeve 5, thereby removing the excess oil droplets on the packing ring 81. These oil droplets then flow out from the porous oil outlet plate 9. After that, the operator climbs onto the elevated platform 1 and rotates the rotating disk 61 to make the oil receiving funnel tank 3 rotate. The strip-shaped elastic piece 83 can remove the oil remaining at the high position of the oil receiving funnel tank 3, and finally discharge it from the porous oil outlet plate 9.
