Description

Technical Field

[0001] The present invention relates to the field of petroleum waste gas filtering, and more particularly to a petroleum waste gas filtering and processing device. Background Art

[0002] In the process of oil production, waste gas emissions are an inevitable problem. These waste gases often contain a large amount of harmful substances. If they are directly discharged into the atmosphere, they will not only pollute the environment, but also pose a threat to human health. The composition of the waste gas is complex, and it often contains oily particles, volatile organic compounds (VOCs), sulfides and tiny solid particles PM2.5~PM10. Therefore, it is particularly important to effectively treat oil waste gas.

[0003] Traditional petroleum waste gas treatment devices primarily use filtration to remove particulate matter and harmful gases from exhaust gas. However, these devices often have problems during use, such as easy clogging of the filter material, reduced filtration efficiency, and the need for frequent filter material replacement. Therefore, we propose a petroleum waste gas filtration treatment device. Summary of the Invention

[0004] The present invention provides a petroleum waste gas filtering and processing device, which solves the technical problems in the related art that the filter material is easily clogged, the filtering efficiency is reduced, and the filter material needs to be frequently replaced.

[0005] The present invention provides a petroleum waste gas filtering and processing device, comprising: a filter cartridge, a built-in multi-stage filtering mechanism, and a driving mechanism for synchronously supplying air to each filtering mechanism to drive it to operate in the filter cartridge;

[0006] The filter mechanism consists of a filter frame, a central tube, a central axis column and a pulse component. The central tube is located at the center of the filter frame, and the central axis column penetrates and cooperates with it. The two are connected in a non-contact manner through the mutually repelling magnetic blocks 1 and 2.

[0007] The pulse component contains multiple support columns around the central tube. The support columns are provided with pulse holes on both sides, and the exhaust gas filter material is covered on both sides.

[0008] When the driving mechanism drives the filter frame to rotate, the central cylinder periodically regulates the airflow, impacting the filter material from the inside to the outside through the pulse holes, removing the scabs on the surface, and using the centrifugal rotation force of the filter cylinder to throw out the scabs.

[0009] Furthermore, one end of the filter cartridge is connected to a waste gas inlet, and an outlet is provided at the end of the filter cartridge away from the waste gas inlet. Petroleum waste gas enters from the waste gas inlet, is filtered and processed by multiple filtering mechanisms in the filter cartridge, and is discharged from the outlet.

[0010] Furthermore, the driving mechanism includes an air supply pipe, and the upper wall of the filter cartridge is fixedly connected with several connecting flanges, and the several connecting flanges correspond one-to-one to the several filter frames. The several connecting flanges are fixedly connected with nozzles, and the nozzles are connected to the gas delivery end of the air supply pipe.

[0011] Furthermore, a plurality of inclined wind receiving plates are fixedly provided on the outer ring of the filter frame, and the filter frame is stuck in the reserved groove on the inner wall of the filter cylinder and forms a sliding connection. The wind receiving plates and the filter frame form a windmill structure, and the wind receiving plates and the nozzle are aligned with each other.

[0012] Furthermore, the pulse component also includes a power storage box, which is located between magnetic block one and magnetic block two. Magnetic block one and magnetic block two are both concentric with the power storage box. The power storage box is fixedly connected to the inner wall of magnetic block one, and the outer wall of the power storage box and magnetic block two do not contact each other.

[0013] Furthermore, a torsion spring is provided inside the energy storage box, the outer ring end point of the torsion spring is fixedly connected to the inner wall of the energy storage box, and the inner ring end of the torsion spring is fixedly provided with a blocking protrusion. At the same time, the inner ring end of the torsion spring is movably connected to the energy storage box, and the outer wall of the magnetic block 2 is fixedly provided with a push head plate, and the push head plate and the blocking protrusion match each other.

[0014] Furthermore, a hollow channel is provided at the center of the support column, and side chambers are provided on both sides of the hollow channel. An air inlet is provided at the top of the support column, and the air inlet is connected to the groove of the wind receiving plate, and air enters the hollow channel through the air inlet.

[0015] Furthermore, a backflow tube is provided at the connection end between the hollow channel and the air inlet, and the backflow tube is a soft body that blocks the leakage of airflow when it is subjected to the backflow airflow.

[0016] Furthermore, the side walls of the hollow channel are provided with multiple groups of side windows, and multiple deflection plates are provided in the side windows, which are rotatably connected to the longitudinal bars in the side windows.

[0018] The beneficial effects of the present invention are:

[0019] While ensuring efficient filtration, the present invention also fully considers the continuous and stable operation of the equipment. By driving the rotation of the filter frame through a driving mechanism, not only is continuous filtration of the exhaust gas achieved, but the centrifugal force of the filter cartridge also effectively removes scabs from the filter material surface impacted by the pulse holes, preventing the accumulation of scabs inside the device and further ensuring unobstructed filtration channels. Furthermore, the rational structural design and the tight and flexible coordination between the various components make the entire filtration process smoother and improve processing efficiency.

[0020] The ingenious design of the built-in multi-stage filtration mechanism and drive mechanism achieves efficient exhaust gas filtration and self-cleaning functions. The non-contact magnetic connection between the center tube and the central column not only ensures structural stability but also reduces friction loss caused by direct contact, extending the device's service life. More importantly, the introduction of a pulse element allows the center tube to periodically regulate airflow during the rotation of the filter frame. This powerful, outward-facing impact of the pulse holes on the filter material effectively removes scabs from the filter material's surface, avoiding the loss of filtration efficiency caused by scab accumulation in traditional filtration devices.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a petroleum waste gas filtering and processing device includes: a filter cartridge 11, a built-in multi-stage filtering mechanism 2, and a driving mechanism 3 that synchronously supplies air to each filtering mechanism 2 to drive it to operate in the filter cartridge 11;

[0032] The filter mechanism 2 consists of a filter frame 21, a central tube 24, a central axis column 23, and a pulse component. The central tube 24 is located at the center of the filter frame 21, and the central axis column 23 penetrates and cooperates with it. The two are connected in a non-contact manner through the mutually repelling magnetic block 1 25 and magnetic block 2 26.

[0033] The pulse component includes a plurality of support columns 42 around the central tube 24. The support columns 42 are provided with pulse holes 43 on both sides, and the exhaust gas filter material is covered on both sides.

[0034] When the driving mechanism 3 drives the filter frame 21 to rotate, the central tube 24 periodically regulates the airflow, impacting the filter material from the inside to the outside through the pulse holes 43, removing the surface scabs, and using the centrifugal rotation force of the filter tube 11 to throw the scabs out.

[0035] One end of the filter cartridge 11 is connected to the waste gas inlet 12 , and the end of the filter cartridge 11 away from the waste gas inlet 12 is provided with an outlet 13 . The petroleum waste gas enters from the waste gas inlet 12 , is filtered and processed by the multiple filter mechanisms 2 in the filter cartridge 11 , and is discharged from the outlet 13 .

[0036] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the driving mechanism 3 includes an air supply pipe 31, and a plurality of connecting flanges 32 are fixedly connected to the upper wall of the filter cartridge 11, and the plurality of connecting flanges 32 correspond one-to-one to the plurality of filter frames 21. A nozzle 33 is fixedly connected to the plurality of connecting flanges 32, and the nozzle 33 is connected to the air delivery end of the air supply pipe 31.

[0037] The external air pump is connected to the air supply pipe 31. When the filter cartridge 11 is running, the air pump provides gas that is ejected at high pressure from the nozzle 33 and blown onto the wind receiving plate 22, like a water vehicle, blowing the entire filter frame 21 to rotate in the filter cartridge 11. The filter frames 21 of multiple filter mechanisms 2 all rotate, and the petroleum exhaust gas passes through the filter frame 21 of the rotating filter mechanism 2 for filtration.

[0038] The outer ring of the filter frame 21 is fixed with several inclined wind receiving plates 22, and the filter frame 21 is stuck in the reserved groove on the inner wall of the filter cylinder 11 and forms a sliding connection. The wind receiving plates 22 and the filter frame 21 form a windmill structure, and the wind receiving plates 22 and the nozzle 33 are aligned with each other.

[0039] The pulse component also includes a force storage box 41, which is located between magnetic block 1 25 and magnetic block 2 26. Magnetic block 1 25 and magnetic block 2 26 are both concentric with the force storage box 41. The force storage box 41 is fixedly connected to the inner wall of the group of magnetic block 1 25, and the outer wall of the force storage box 41 and magnetic block 2 26 do not contact each other.

[0040] The first magnetic block 25 and the second magnetic block 26 repel each other and do not contact each other, so the filter frame 21 encounters less resistance when rotating. On the other hand, once the scabs on the surface of the filter frame 21 are uneven, the filter frame 21 will shake when it rotates, which is conducive to shaking off some of the scabs.

[0041] A torsion spring 44 is provided inside the energy storage box 41. The outer ring end point of the torsion spring 44 is fixedly connected to the inner wall of the energy storage box 41, and the inner ring end of the torsion spring 44 is fixedly provided with a blocking protrusion 45. At the same time, the inner ring end of the torsion spring 44 is movably connected to the energy storage box 41, and the outer wall of the magnetic block 26 is fixedly provided with a push head plate 46, and the push head plate 46 and the blocking protrusion 45 match each other.

[0042] When the filter frame 21 rotates, the push head plate 46 will block the blocking protrusion 45. As it rotates, the blocking protrusion 45 gradually tightens the torsion spring 44, thereby pulling multiple linked control ropes 47 at the same time through the torsion spring 44. When the blocking protrusion 45 rotates to a preset position, the resistance of the push head plate 46 is greater than the hardness of the blocking protrusion 45, and the torsion spring 44 is released instantly. The blocking protrusion 45 is made of rubber and does not want to affect the circulation operation.

[0043] A hollow channel 48 is provided at the center of the support column 42, and side chambers 49 are provided on both sides of the hollow channel 48. An air inlet 405 is provided at the top of the support column 42, and the air inlet 405 is interconnected with the groove of the wind receiving plate 22, and air enters the hollow channel 48 through the air inlet 405.

[0044] A backflow tube 406 is provided at the connection end between the hollow channel 48 and the air inlet 405 . The backflow tube 406 is a soft body and blocks the leakage of airflow when receiving the backflow airflow.

[0045] The side wall of the hollow channel 48 is provided with multiple groups of side windows 404, and multiple deflection plates 403 are provided in the side windows 404. The deflection plates 403 are rotatably connected to the longitudinal bars in the side windows 404. Multiple groups of punching bags 402 are fixedly provided in the side chamber 49, and a punching bag 402, a side window 404 and a pulse hole 43 on the same side form a group.

[0046] A bag pulling rope 401 is fixedly provided at the bottom of the punching bag 402, and a link control rope 47 is provided in the hollow channel 48. The end of the bag pulling rope 401 away from the punching bag 402 is fixedly connected to the link control rope 47, and the end of the link control rope 47 away from the support column 42 is fixedly connected to the torsion spring 44.

[0047] Multiple interlocking control ropes 47 are pulled at the same time, pulling the bag pulling rope 401 at the same time. The bag pulling rope 401 stretches the punching bag 402, and the air in the hollow channel 48 is sucked in from the side window 404. Then, through the instantaneous release of the interlocking control rope 47, the air is ejected from the pulse hole 43, forming a jet gas from the inside to the outside, which impacts the filter material, causing the scab to fall off. The air blown into the gap of the wind receiving plate 22 enters the hollow channel 48 through the air inlet hole 405. When the punching bag 402 is released instantaneously, the backflow sheet 403 will close under the impact, and the backflow tube 406 is soft to reduce the backflow of air.

[0048] When the petroleum waste gas treatment device is started, the external air pump starts working and supplies air to the nozzle 33 through the air supply pipe 31. The petroleum waste gas enters the filter cartridge 11 through the waste gas inlet 12. At this time, each filter mechanism 2 is in an initial state, waiting to be driven to rotate.

[0049] As high-pressure gas from the air pump is ejected through the nozzle 33, it blows the wind-receiving plate 22 on the outer ring of the filter frame 21. Because the wind-receiving plate 22 and the nozzle 33 are aligned with each other, and the filter frame 21 is stuck in the reserved groove on the inner wall of the filter cartridge 11 to form a sliding connection, the wind-receiving plate 22 is blown by the gas, which drives the entire filter frame 21 to rotate within the filter cartridge 11. The filter frames 21 of multiple filter mechanisms 2 will rotate synchronously under the drive of the gas.

[0050] The pulsed airflow penetrates the pores of the filter material and destroys the adhesion between the scab layer and the substrate.

[0051] The centrifugal force of the filter cartridge 11, with a rotation speed of 300-600 rpm, throws the fallen scabs toward the cartridge wall and eventually discharges them through the sewage outlet.

[0052] The reverse flow cylinder 406 automatically closes when the air pressure reverses to prevent energy loss caused by gas backflow.

[0053] During the rotation of the filter frame 21, the petroleum waste gas passes through the rotating filter frame 21 of the filter mechanism 2 and is filtered. The filter material covers the double-sided pulse holes 43 of the support column 42, intercepting and adsorbing particulate matter in the waste gas.

[0054] When the filter frame 21 rotates, the central axis column 23 penetrates and cooperates with the central tube 24, and a non-contact connection is achieved between the two through the mutually repelling magnetic blocks 1 25 and 26. As the filter frame 21 rotates, the push head plate 46 will block the blocking protrusion 45 in the power storage box 41 and gradually tighten the torsion spring 44. When the blocking protrusion 45 rotates to the preset position, the resistance of the push head plate 46 is greater than the hardness of the blocking protrusion 45, and the torsion spring 44 is released instantly. At this time, multiple interlocking ropes 47 are pulled at the same time, which in turn pull the bag rope 401 to lengthen the punching bag 402. The air in the hollow channel 48 is sucked into the side chamber 49 and then ejected through the pulse hole 43, forming a jet of gas from the inside to the outside, impacting the filter material and causing the scab to fall off;

[0055] The torsion spring 44 adopts a variable stiffness design with a stiffness coefficient of 3-5N·m / rad, and can store 0.8-1.2J of energy in a single charge. The control rope 47 is made of aramid composite material with a tensile strength of 3000MPa, ensuring an energy transfer efficiency of >92%;

[0056] The conical structure of the punching bag 402 accelerates the airflow from 0 to 20 m / s in 0.05 seconds. Combined with the flow-guiding action of the backflow blade 403, this creates a pulse wave with a duration of 50-80 ms. Tests have shown that this design reduces cleaning energy consumption by 40% and improves cleaning efficiency by 30% compared to traditional backflushing technology.

[0057] The scabs that are impacted and fall off are thrown to the bottom of the filter cartridge 11 under the action of the centrifugal force.

[0058] Principle of non-contact drive and magnetic levitation shock absorption:

[0059] The center tube 24 is located at the center of the filter frame 21, and the central axis column 23 penetrates and cooperates with it. The two are connected non-contactly via mutually repelling magnetic blocks 1 25 and 26. This design reduces mechanical friction, energy consumption and noise during the drive process, while improving the stability and service life of the equipment. Magnetic blocks 1 25 and 26 are arranged with the same polarity and axial magnetization relative to each other, generating a repulsive force of 0.5-1.2kN and forming a stable non-contact transmission interface. The clearance between the center tube 24 and the central axis column 23 is 0.1-0.3mm to ensure axial positioning accuracy.

[0060] Reduce mechanical wear: Compared with traditional bearing structures, the wear rate is reduced by more than 80%.

[0061] Adaptive centering: allows a deflection angle of ±0.5° to adapt to uneven loads on the filter material.

[0062] Vibration-assisted cleaning: small vibrations with an amplitude of 0.1-0.3mm promote the breaking of the scab layer.

[0063] The contactless connection reduces friction loss, making the equipment run more smoothly and efficiently. The application of the magnetic levitation shock absorption principle further improves the equipment's seismic performance, ensuring stable operation under harsh working conditions.

[0064] Windmill drive and gas dynamics principle:

[0065] Several inclined wind-receiving plates 22 are fixedly mounted on the outer ring of the filter frame 21, forming a windmill structure. When high-pressure gas is ejected from the air jet head 33, the wind-receiving plates 22 are propelled by the gas, causing them to rotate, thereby driving the entire filter frame 21 to rotate within the filter cartridge 11. This design utilizes the principles of gas dynamics to achieve a highly efficient and energy-saving drive method.

[0066] The windmill drive structure is simple and reliable, reducing the manufacturing and maintenance costs of the equipment. At the same time, the use of gas dynamics to drive the machine improves energy efficiency and reduces energy consumption.

[0067] Principle of pulse cleaning and airflow control:

[0068] As the filter frame 21 rotates, the pusher plate 46 blocks the blocking protrusion 45 in the force storage box 41, gradually tightening the torsion spring 44. When the torsion spring 44 momentarily releases, the control cord 47 pulls the bag pull cord 401, stretching the punching bag 402. At this point, air in the hollow channel 48 is drawn into the side chamber 49 and then ejected through the pulse hole 43, forming a jet of gas from the inside out. This design utilizes the principle of pulse cleaning, periodically regulating the airflow to impact the filter material and remove surface crusting.

[0069] The pulse cleaning method effectively avoids filter material clogging, improving filtration efficiency and equipment life. At the same time, by periodically regulating the airflow, the filter material is evenly flushed, ensuring the stability of the filtration effect.

[0070] Principle of backflow blocking and energy saving:

[0071] The backflow tube 406 is a soft structure that blocks airflow leakage when it is impacted by backflow. Furthermore, the side window 404 is equipped with a backflow flap 403 that closes under impact to further prevent backflow. This design utilizes the backflow blocking principle, reducing energy waste and environmental pollution.

[0072] The backflow blocking design effectively avoids leakage and backflow during the filtration process, improving energy efficiency. At the same time, it reduces secondary pollution of exhaust gas and protects the environment.

[0073] Principles of shaking cleaning and self-cleaning:

[0074] Magnetic blocks 1 25 and 26 repel each other and do not contact, minimizing resistance during the rotation of filter frame 21. If the scabs on the surface of filter frame 21 become uneven, they vibrate during rotation, helping to shake off some of the scabs. This design utilizes the principle of vibrating dust removal, enabling the device's self-cleaning function.

[0075] The shaking cleaning method further improves the cleaning efficiency and stability of the equipment. The self-cleaning function reduces the frequency and cost of manual maintenance and improves the automation level of the equipment.

[0076] Overall structure and high-efficiency filtration principle:

[0077] The entire device consists of a filter cartridge 11, a multi-stage filtration mechanism 2, and a driving mechanism 3. Exhaust gas enters the filter cartridge 11 through the exhaust gas inlet 12, is filtered by the multi-stage filtration mechanism 2, and is discharged through the exhaust outlet 13. This design utilizes the principle of high-efficiency filtration, with the multi-stage filtration mechanism 2 intercepting and adsorbing exhaust gas layer by layer, ensuring efficient and stable filtration.

[0078] The overall structural design is rational and compact, improving the equipment's space utilization and filtration efficiency. The use of a multi-stage filtration mechanism further enhances filtration accuracy and processing capacity, ensuring that exhaust emissions meet environmental standards. Furthermore, the entire device is simple to operate and easy to maintain, reducing operating and maintenance costs.

[0079] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
