Description

Technical Field

[0001] This invention relates to the field of petroleum descaling technology, specifically to a detachable oil and gas impurity pre-filtration treatment device. Background Technology

[0002] In the petroleum, chemical, and energy industries, oil and gas-containing fluids often carry colloids, particulate matter, and organic impurities. If these untreated fluids directly enter the fine filtration system, they can easily cause membrane module clogging and damage. Therefore, pre-filtration, as a critical upstream step, directly determines the stable operation of subsequent processes and the service life of the equipment.

[0003] However, existing technologies mainly rely on the principle of static permeation, which makes it easy for contaminants (especially colloids) to accumulate on the membrane surface and form a dense boundary layer. This boundary layer not only leads to a continuous decline in permeation efficiency, but also makes it difficult for conventional backwashing operations to completely remove firmly attached colloidal deposits.

[0004] Furthermore, existing mechanical vibration cleaning mechanisms typically employ a fixed amplitude design, failing to dynamically adjust according to the actual degree of oil contamination. This results in insufficient cleaning intensity and incomplete removal of contaminants under high contamination conditions, while excessive vibration under low contamination conditions accelerates physical damage to the membrane material. Additionally, the current filter element design makes disassembly complex and cumbersome, significantly extending downtime for maintenance. To compensate for insufficient cleaning, frequent chemical cleaning is often required, but this strong chemical action further shortens the filter membrane's lifespan.

[0005] Therefore, a detachable oil and gas impurity pre-filtration treatment device is proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a detachable oil and gas impurity pre-filtration treatment device to solve the problems in the prior art where impurities are easily attached to the membrane surface during ultrafiltration of oil and gas and are difficult to clean, and the static permeation of ultrafiltration oil membrane increases the risk of membrane pore blockage.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a detachable oil and gas impurity pre-filtration treatment device, including a mounting frame, a control cabinet mounted on the mounting frame, an oil inlet device and an oil outlet device mounted on both sides of the mounting frame respectively, an oil and gas impurity filter cover evenly mounted in the middle of the mounting frame, and the oil inlet device and the oil outlet device respectively connected to both ends of the oil and gas impurity filter cover. The oil and gas impurity filter cover is equipped with a self-cleaning mechanism and a linkage adjustable braking mechanism. The self-cleaning mechanism is used for the initial filtration and cleaning of oil and gas, and the linkage adjustable braking mechanism is used for the purification and anti-clogging adjustment of oil and gas.

[0008] Preferably, the self-cleaning mechanism includes an oil collection chamber, which is located at one end of the oil and gas impurity filter cover. A first sludge collection trough is provided in the oil collection chamber for the sedimentation and collection of impurities. A first filter disc is fixedly installed on the inner wall of the oil and gas impurity filter cover near the inner wall of the oil collection chamber. An arc-shaped guide plate is fixedly installed on the inner wall of the oil and gas impurity filter cover on the side away from the oil collection chamber from the first filter disc.

[0009] Preferably, a second filter disc is provided on the side of the arc-shaped guide plate away from the first filter disc. The outer surface of the second filter disc is fixedly installed on the inner wall of the oil and gas impurity filter cover. A turbine blade scraper is rotatably installed in the middle of the side of the second filter disc near the arc-shaped guide plate. A drive shaft is fixedly connected to the middle of the turbine blade scraper. The outer surface of the drive shaft is rotatably connected in the second filter disc.

[0010] Preferably, the linkage adjustable braking mechanism includes a drive plate, one end of which is fixedly mounted on a transmission shaft, and the other end of the drive plate away from the transmission shaft is provided with a spherical shaft. Spherical bushings are installed at both ends of the spherical shaft, and a slide is provided at the end of the spherical shaft away from the drive plate. The spherical bushings are respectively mounted on the drive plate and the slide.

[0011] Preferably, a guide groove is slidably installed at the bottom of the slide block, a linkage rod is installed in the middle of the guide groove, a third filter disc is fixedly installed at the bottom of the guide groove, the outer surface of the third filter disc is fixedly installed on the inner wall of the oil and gas impurity filter cover, a filter scraper is fixedly installed on the lower side of the third filter disc, and a second sludge collection groove is opened on the side of the oil and gas impurity filter cover near the third filter disc, and the filter scraper is slidably installed in the second sludge collection groove.

[0012] Preferably, an ultrafiltration oil membrane is installed on the side of the third filter disc away from the guide groove, and the end of the ultrafiltration oil membrane away from the third filter disc is fixedly connected to a filtration chamber. The ultrafiltration oil membrane is fixedly installed on the inner wall of the oil and gas impurity filter cover, and the ultrafiltration oil membrane is evenly distributed on the third filter disc. The ultrafiltration oil membrane and the third filter disc are fixed to each other and not connected.

[0013] Preferably, the quick-release adjustment mechanism includes a guide bracket, which is mounted on a mounting frame. The guide bracket has symmetrical guide grooves in the middle, and a bearing is slidably installed in the guide groove. The inner surface of the bearing is rotatably mounted on the oil and gas impurity filter cover. Flanges are provided at both ends of the oil and gas impurity filter cover, and an auxiliary pull plate is installed in the middle of the oil and gas impurity filter cover. The auxiliary pull plate is used for quick pulling of the oil and gas impurity filter cover.

[0014] Compared with the prior art, the detachable oil and gas impurity pre-filtration treatment device provided by the present invention has the following beneficial effects: 1. This solution allows the ultrafiltration oil membrane to move during oil and gas permeation. The vibration generated by the movement of the ultrafiltration oil membrane can break the stagnant boundary layer on the membrane surface, accelerate the diffusion of solute from the membrane surface to the main fluid, thereby reducing the local osmotic pressure, increasing the water flux, i.e. the permeation rate, and improving the water production efficiency.

[0015] 2. This solution prevents particles, colloidal organic matter, and other contaminants from depositing on the surface of the ultrafiltration oil membrane due to prolonged permeation during the external permeation process. Furthermore, existing backwashing techniques often fail to remove this contaminant. This solution, however, utilizes the continuous movement of the ultrafiltration oil membrane within the oil and gas impurity filter hood to generate friction and vibration between the membrane surfaces. This vibration and friction removes the adhering particles and colloids, reducing the frequency of membrane cleaning and increasing the membrane's lifespan.

[0016] 3. This solution utilizes an adjustable braking mechanism to regulate the amplitude of the ultrafiltration oil membrane's cleaning action against uneven oil and gas, enabling dynamic adaptation to changes in oil stains. For highly contaminated oil stains, adjusting the slide distance increases the amplitude of the ultrafiltration oil membrane, enhancing the removal of deposits from its surface. Conversely, for low-contamination oil stains, adjusting the slide distance reduces the amplitude of the ultrafiltration oil membrane, preventing excessive disturbance and membrane damage. This solution improves cleaning efficiency by 40% for contaminants containing colloids and other pollutants.

[0017] 4. With the self-cleaning mechanism, this solution utilizes the flushing action of oil and gas, guided by the arc-shaped baffle, to directly flush the surface of the turbine blade scraper, driving the turbine blade scraper to move. The movement of the turbine blade scraper provides power support for the linkage adjustable braking mechanism, while the rotation of the turbine blade scraper also reduces the clogging of the second filter disc surface. Furthermore, this solution achieves layered cleaning of different impurities through multi-layer filtration, avoiding direct clogging of the ultrafiltration oil film surface by large particles.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] Example 1, please refer to Figures 1 to 8 As shown: To address the problems mentioned in the technical solutions, this application provides a detachable oil and gas impurity pre-filtration treatment device, including a mounting frame 1, a control cabinet 11 mounted on the mounting frame 1, an oil inlet device 12 and an oil outlet device 13 mounted on both sides of the mounting frame 1, and an oil and gas impurity filter cover 14 evenly mounted in the middle of the mounting frame 1. The oil inlet device 12 and the oil outlet device 13 are respectively installed and connected to both ends of the oil and gas impurity filter cover 14. The oil and gas impurity filter cover 14 is equipped with a self-cleaning mechanism 2 and a linkage adjustable braking mechanism 3. The self-cleaning mechanism 2 is used for the initial filtration and cleaning of oil and gas, and the linkage adjustable braking mechanism 3 is used for the purification and anti-clogging adjustment of oil and gas.

[0023] Specifically, such as Figure 5As shown, an oil collection chamber 21 is located at one end of an oil and gas impurity filter cover 14. A first sludge collection trough 22 is provided in the oil collection chamber 21 for the sedimentation and collection of impurities. A first filter disc 23 is fixedly installed on the inner wall of the oil and gas impurity filter cover 14 near the inner wall of the oil collection chamber 21. An arc-shaped guide plate 24 is fixedly installed on the inner wall of the oil and gas impurity filter cover 14 on the side away from the oil collection chamber 21, near the first filter disc 23. A second filter disc 26 is provided on the side of the arc-shaped guide plate 24 away from the first filter disc 23. The outer surface of the second filter disc 26 is fixedly installed on the inner wall of the oil and gas impurity filter cover 14. A turbine blade scraper 25 is rotatably installed in the middle of the side of the second filter disc 26 near the arc-shaped guide plate 24. A drive shaft 31 is fixedly connected to the middle of the turbine blade scraper 25. The outer surface of the drive shaft 31 is rotatably connected to the second filter disc 26.

[0024] In this scheme, the pressure of the water pump drives the oil and gas to flow in the oil and gas impurity filter cover 14. The oil and gas can be flushed onto the turbine blade scraper 25 by the guide of the turbine blade scraper 25, thereby driving the turbine blade scraper 25 to rotate on the second filter plate 26. The kinetic energy of the water flow is converted into the mechanical energy of the turbine blade scraper 25 rotation, which can not only reduce the blockage of large particles of impurities on the surface of the second filter plate 26, but also drive the linkage adjustable braking mechanism 3 to move by the rotation of the turbine blade scraper 25, thereby increasing the green treatment process of wastewater utilization.

[0025] Specifically, such as Figure 6 and Figure 8 As shown, one end of the drive plate 32 is fixedly mounted on the transmission shaft 31, and the other end of the drive plate 32 away from the transmission shaft 31 is provided with a spherical shaft 34. Spherical bushings 33 are installed at both ends of the spherical shaft 34, and a slide block 35 is provided at the end of the spherical shaft 34 away from the drive plate 32. The spherical bushings 33 are respectively mounted on the drive plate 32 and the slide block 35.

[0026] The spherical shaft 34 is connected to the spherical bushing 33 by spherical connecting blocks at both ends, which allows the spherical shaft 34 to slide in the spherical bushing 33 and achieve multi-angle rotation of the spherical shaft 34.

[0027] A guide groove 36 is slidably installed at the bottom of the slide block 35. A linkage rod 37 is installed in the middle of the guide groove 36. A third filter disc 301 is fixedly installed at the bottom of the guide groove 36. The outer surface of the third filter disc 301 is fixedly installed on the inner wall of the oil and gas impurity filter cover 14. A filter scraper 302 is fixedly installed on the lower side of the third filter disc 301. A second sludge collection tank 303 is opened on the side of the oil and gas impurity filter cover 14 near the third filter disc 301. The filter scraper 302 is slidably installed in the second sludge collection tank 303.

[0028] The linkage 37 can be a fixed support rod or a lead screw, and the motion limit value of the ultrafiltration oil membrane 38 material in this application is greater than the amplitude motion generated by the motion of the ultrafiltration oil membrane 38.

[0029] When the linkage rod 37 is a fixed support rod, the slide 35 can be fixedly installed in the guide groove 36 through the linkage rod 37, and the position of the slide 35 in the guide groove 36 can be fixed by controlling the length of the linkage rod 37.

[0030] When the linkage rod 37 is a lead screw, one end of the lead screw is rotatably installed in the slide block 35, and the other end is threaded on the outer surface and installed in the guide groove 36. At the same time, a waterproof servo motor is installed on the other end. The servo motor can drive the linkage rod 37 to rotate through the controller. The rotation of the linkage rod 37 can make the slide block 35 slide in the guide groove 36. Thus, the sliding distance of the third filter disc 301 inside the oil and gas impurity filter cover 14 can be controlled by the rotation of the ball shaft 34 at different positions of the slide block 35. Thus, the third filter disc 301 can drive the ultrafiltration oil membrane 38 to vibrate in the oil and gas impurity filter cover 14. In this solution, the length of the ultrafiltration oil membrane 38 is greater than the distance between the filter chamber 39 and the third filter disc 301 to prevent the ultrafiltration oil membrane 38 from being pulled and damaged when the third filter disc 301 slides. The distance of the ultrafiltration oil membrane 38 is greater than the maximum sliding distance of the third filter disc 301 plus the distance between the filter chamber 39 and the third filter disc 301.

[0031] An ultrafiltration oil membrane 38 is installed on the side of the third filter disc 301 away from the guide groove 36. The end of the ultrafiltration oil membrane 38 away from the third filter disc 301 is fixedly connected to the filter chamber 39. The ultrafiltration oil membrane 38 is fixedly installed on the inner wall of the oil and gas impurity filter cover 14. The ultrafiltration oil membrane 38 is evenly distributed on the third filter disc 301, and the ultrafiltration oil membrane 38 and the third filter disc 301 are fixed to each other but not connected.

[0032] The quick-release adjustment mechanism 4 includes a guide bracket 41, which is mounted on the mounting bracket 1. The guide bracket 41 has symmetrical guide grooves 42 in the middle. A bearing 43 is slidably installed in the guide groove 42. The inner surface of the bearing 43 is rotatably mounted on the oil and gas impurity filter cover 14. Flanges 44 are provided at both ends of the oil and gas impurity filter cover 14. An auxiliary pull plate 45 is installed in the middle of the oil and gas impurity filter cover 14. The auxiliary pull plate 45 is used for quick pulling of the oil and gas impurity filter cover 14.

[0033] Example 2 illustrates a heavy crude oil pretreatment line in an oil refinery. When processing heavy crude oil with high colloidal and particulate matter content, the traditional pre-filtration system frequently clogs, requiring daily shutdowns for chemical cleaning, resulting in a 30% decrease in production efficiency. Three sets of oil and gas impurity filter hoods 14 are installed in parallel between the inlet pump 12 and the fine filtration system via a quick-release adjustment mechanism 4. The control cabinet 11 is connected to the plant's DCS system.

[0034] At this time, the terminal system controls the control cabinet 11, which then starts the equipment via electrical signal transmission. Under the pressure of the inlet pump installed on the mounting frame 1, the oil and gas from vanadium extraction from the coal begins to enter the oil and gas impurity filter hood 14. Figure 4 and Figure 5 As shown, when the oil and gas first enter the oil collecting chamber 21 through the oil inlet device 12, the oil and gas begin to flow into the side of the first filter disc 23 away from the oil collecting chamber 21 under the initial filtration effect of the first filter disc 23. At this time, the oil and gas begin to flow along the arc surface of the arc-shaped guide plate 24 under the pressure of the water inlet pump. Under the guidance of the arc-shaped guide plate 24, the oil and gas begin to wash onto the arc surface of the turbine blade scraper 25. At this time, under the washing action of water, the turbine blade scraper 25 will drive the second filter disc 26 to rotate. 6. Membrane technology is used to filter large particles of impurities. The filtered impurities are scraped by the rotating turbine blade scraper 25 to prevent large particles of impurities from clogging the gaps of the turbine blade scraper 25. This application uses the pressurized flow rate of oil and gas to drive the turbine blade scraper 25 to achieve mechanical rotation. The scraping between the bottom of the turbine blade scraper 25 and the second filter plate 26 can reduce the accumulation and clogging of impurities on the surface of the second filter plate 26, and prevent the clogging caused by oil and gas filtration from causing low equipment purification efficiency and reduced equipment service life.

[0035] Furthermore, when the turbine blade scraper 25 rotates, since the middle part of the turbine blade scraper 25 is fixed to the drive shaft 31, the rotation of the turbine blade scraper 25 will drive the drive shaft 31 to rotate synchronously. When the drive shaft 31 rotates, it will drive the drive plate 32 to start rotating on the surface of the second filter disc 26. The contact between the second filter disc 26 and the drive plate 32 can prevent the filter holes inside the second filter disc 26 from being blocked due to long-term adhesion of oil and gas. At the same time, since both ends of the spherical shaft 34 are installed in the spherical bushing 33, when the drive plate 32 rotates around the middle part of the drive shaft 31, the spherical bushing 33 will drive the spherical shaft 34 to drive the slide block 35 to move. Since the spherical shaft 34 is installed on the guide groove 36 and fixed in the guide groove 36 by the linkage rod 37, this scheme is designed in two ways: The first method uses a lead screw for the linkage rod 37 and a sealed, waterproof micro servo motor installed on the third filter disc 301 to drive the linkage rod 37 to rotate. The rotation of the linkage rod 37 causes the slide block 35 to slide in the guide groove 36. When the slide block 35 is fixed in different positions in the guide groove 36, the ball joint 34 drives the slide block 35 to pull the third filter disc 301 to slide different distances on the inner wall of the oil and gas impurity filter cover 14. This causes the ultrafiltration oil membrane 38 to vibrate at different frequencies within the oil and gas impurity filter cover 14. Therefore, in specific application scenarios, the amplitude of the ultrafiltration oil membrane 38 can be controlled by automatically controlling the servo motor. This allows for control of the amplitude of the ultrafiltration oil membrane 38 in different scenarios, reducing the likelihood of impurities in the oil and gas adhering to the outer surface of the ultrafiltration oil membrane 38 for extended periods, thus preventing low permeability and external blockage. Figure 6 As shown, the oil and gas located on the left side of the third filter disc 301 flow into the outer surface of the ultrafiltration oil membrane 38 under the filtration of the third filter disc 301. At this time, the impurities can be filtered onto the outer surface of the ultrafiltration oil membrane 38 through the permeation effect of the ultrafiltration oil membrane 38. At this time, the ultrafiltration oil membrane 38 is shaken at different frequencies by the third filter disc 301 in the oil and gas impurity filter cover 14, which can cause the impurities on the outer surface of the ultrafiltration oil membrane 38 to fall into the oil and gas impurity filter cover 14. When the equipment is not in use, the equipment backwashing technology is used to inject cleaning water into the filter chamber 39 through the cleaning port on the oil outlet device 13. At this time, the water will enter the ultrafiltration oil membrane 38, backwashing some of the impurities blocked in the filter pores of the ultrafiltration oil membrane 38 into the second collection tank 303. The discharge and collection of impurities in the oil and gas can be achieved by disassembling the second collection tank 303. In this solution, the second collection tank 303 adopts a quick-release interface, and the interface and the second collection tank 303 have good sealing performance.

[0036] The second method is to fix the slide block 35 in the guide groove 36 by means of the linkage rod 37. By fixing the slide block 35 in the guide groove 36 in the initial state, the amplitude can be stabilized, so that the third filter disc 301 can always drive the ultrafiltration oil film 38 to be in the same amplitude.

[0037] This solution disrupts the stagnant boundary layer on the surface of the ultrafiltration oil membrane 38 through vibration, accelerating the diffusion of solutes from the membrane surface to the main fluid. This not only reduces local osmotic pressure, increases water flux permeation rate, and improves water production efficiency, but also effectively mitigates membrane fouling. The shear force generated by vibration prevents the deposition of particles, colloids, and organic matter on the membrane surface, reducing the need for chemical cleaning, extending cleaning cycles, and lowering maintenance costs such as cleaning agents and downtime. Under the same operating pressure, vibration can increase flux by 20%–50%. To achieve the same flux, operating pressure can be reduced, decreasing high-pressure pump energy consumption. This solution, through vibration, can replace the traditional high-flow-rate, high-energy-consumption turbulent antifouling mode, achieving overall energy reduction while minimizing the impact of high-flow oil scouring on the lifespan of the ultrafiltration oil membrane 38.

[0038] In summary, this solution has the following advantages over existing technologies: (1) Dynamic vibration anti-clogging design: The active vibration of the ultrafiltration oil membrane 38 breaks the stagnant boundary layer on the membrane surface, accelerates the diffusion of pollutants, and significantly reduces the osmotic pressure. Compared with traditional static filtration, it can increase water flux by 20% to 50%, while using vibration friction to remove colloidal deposits, reducing the frequency of chemical cleaning and extending membrane life.

[0039] (2) Adaptive amplitude adjustment technology: The linkage adjustable braking mechanism 3 dynamically controls the amplitude of the ultrafiltration oil membrane 38 through the position of the slide 35: the amplitude is increased to enhance the removal of dirt when the pollution is high, and the amplitude is reduced to avoid membrane damage when the pollution is low. In particular, the cleaning efficiency of wastewater containing colloidal substances is improved by 40%, realizing intelligent optimized operation under oil stain fluctuations.

[0040] (3) Turbine-driven self-cleaning system: The turbine blade scraper 25 is driven to rotate by the kinetic energy of oil and gas, and simultaneously achieves three functions: scraping off impurities on the surface of the second filter plate 26 to prevent clogging; providing power to the vibration mechanism through the transmission shaft 31; converting fluid energy into mechanical energy, reducing additional energy consumption and improving the level of greening.

[0041] (4) Graded filtration and stratified collection of dirt: The three-stage filter discs 23 / 26 / 301 and the ultrafiltration oil membrane 38 form a gradient filtration: the first filter disc 23 intercepts large particles, the second filter disc 26 filters medium impurities, and the ultrafiltration oil membrane 38 finely filters colloids. The first and second dirt collection tanks 22 / 303 collect sediment in layers to avoid cross-accumulation of pollutants and reduce the risk of membrane clogging.

[0042] (5) Quick-release maintenance structure reduces costs and increases efficiency: The guide bracket 41 and the bearing 43 form a sliding track, and the auxiliary pull plate 45 realizes the quick pull-out and disassembly of the filter cover 14. The maintenance time is shortened by more than 50%, reducing downtime losses; combined with the vibration self-cleaning mechanism, the frequency of chemical cleaning is reduced, and the overall operation and maintenance cost is reduced by 30%.

[0043] (6) Dual optimization of energy consumption and lifespan: Vibration anti-clogging replaces the traditional high-flow-rate flushing mode, reducing the energy consumption of high-pressure pumps; the amplitude adaptive mechanism avoids excessive membrane damage and extends the service life of ultrafiltration oil membrane by 38; the overall water production rate is increased by 40% compared with the background technology attenuation value, which is suitable for high-pollution wastewater scenarios such as vanadium extraction from coal.
