Description

Technical Field

[0001] The present invention relates to the technical field of petroleum associated gas, and in particular to a petroleum associated gas processing device and a processing process. Background Art

[0002] Associated gas refers to natural gas that coexists with petroleum. It is the gas that escapes from the oil layer along with crude oil during the oil extraction process. Its main component is methane, and it also contains a certain amount of hydrocarbon gases such as ethane, propane, butane, and a small amount of non-hydrocarbon gases such as carbon dioxide, nitrogen, and hydrogen sulfide. Associated gas can be directly burned as a high-quality fuel for power generation, heating, etc.

[0003] The processing flow of associated petroleum gas mainly includes three steps: first, use a cyclone separator to separate the droplets carried in the associated gas. Since associated petroleum gas often contains a certain amount of liquid hydrocarbons, water and other droplets, the cyclone separator can make the gas-liquid mixture form a high-speed rotating airflow. Due to their large mass, the droplets are thrown to the wall of the separator under the action of centrifugal force and gather into larger droplets, so that the droplets are thrown to the wall of the device and flow down to complete the gas-liquid separation; second, the associated gas after the droplets are separated is filtered for impurities, that is: relying on the filter plate to effectively intercept tiny impurity particles to ensure the passage of pure gas; third, oil and gas separation is carried out to make the associated gas reach the expected quality standards to meet the needs of different application scenarios such as transportation, storage, power generation and as chemical raw materials.

[0004] There are many defects in the existing associated petroleum gas processing equipment. The traditional separation method of mixed droplets in associated petroleum gas lacks efficient centrifugal force, and the separation efficiency between water and associated gas is low, which affects the efficiency and quality of the overall processing process; secondly, the movement mode of the equipment filtering components is single, which leads to uneven local contact of the associated gas, impurities are easily missed, and the filtration efficiency is low. In addition, impurities adhere to the equipment for a long time, which is not convenient for cleaning, thereby increasing the risk of equipment corrosion, shortening its service life, and making the equipment update and maintenance costs high; finally, the oil and gas separation effect in the associated gas processing equipment is not good, which reduces the overall working efficiency of the associated gas processing equipment. Summary of the invention

[0005] The present invention provides a petroleum associated gas processing device and a processing process, which are used to solve the defects of low dehydration efficiency of petroleum associated gas processing in the prior art, single filtering effect on associated gas, inconvenience in cleaning the filter disc, and poor oil-gas separation effect of petroleum associated gas, thereby causing low working efficiency of the associated gas processing equipment.

The first cylindrical gear and the second cylindrical gear are both meshed with gear 3.

[0012] According to a petroleum associated gas processing equipment provided by the present invention, the rotating propulsion mechanism includes two telescopic rods, a "U"-shaped push rod, a filter disc, a support sleeve, a propulsion rod, and a screw. One end of the two telescopic rods is fixedly mounted on the second pulley, and the other end is movably connected to the "U"-shaped push rod. One end of the filter disc is fixedly connected to the "U"-shaped push rod, and the other end is movable inside the filter cylinder. The support sleeve is sleeved on the outer surface of the propulsion rod and fixedly mounted on the second pulley. One end of the propulsion rod is fixedly connected to the "U"-shaped push rod, and the other end is screwed to the screw. The screw passes through the second pulley and is fixedly mounted on the first cylindrical gear.

[0013] According to a petroleum associated gas processing device provided by the present invention, the translation and rotation mechanism includes a translation rod, a sleeve column, a limit stop block, and a limit sleeve rod. One end of the translation rod is fixedly connected to gear three, and the other end is fixedly connected to the sleeve column. The translation rod is movably connected to the fixed plate. The limit stop block is fixedly installed on the top of the device chamber, and the surface of the sleeve column is provided with a groove that movably contacts the limit stop block. The limit sleeve rod is fixedly connected to the sleeve column.

[0014] According to a petroleum associated gas processing equipment provided by the present invention, the oil and gas removal mechanism includes four elastic telescopic parts, two circular ring plates, four "V"-shaped plates, and multiple "L"-shaped plates. The four elastic telescopic parts are respectively fixedly mounted on the surfaces on both sides of the limiting sleeve. The two circular ring plates are respectively fixedly connected to each elastic telescopic part, and the two circular ring plates are both sleeved on the limiting sleeve. Both ends of each "V"-shaped plate are fixedly connected between the two circular ring plates. Each "L"-shaped plate is installed in an array on the surface of each "V"-shaped plate. A card slot movably connected to the limiting column is provided at one end of the limiting sleeve. Four card strips connected to the limiting sleeve for limiting are installed on the surface of the limiting column.

[0015] According to the present invention, a petroleum associated gas processing equipment also includes a separation chamber, which is fixedly mounted on the other side of the upper surface of the supporting base. A connecting pipe is connected through one end of the bottom side of the separation chamber, and the other end of the connecting pipe is fixedly connected to the bottom of the surface of the filter cartridge. An air outlet pipe is connected through the top of the separation chamber, and a liquid outlet pipe is connected through the bottom. The limiting sleeve rod penetrates the surface of the separation chamber and is movably connected to the limiting column.

[0016] According to the petroleum associated gas processing equipment provided by the present invention, an air inlet pipe is connected to one end of the top of the separation box, and a liquid discharge pipe is connected to the bottom of one side of the separation box. A sleeve ring is fixedly installed on the inner wall of the filter cartridge, and an elastic impact block is fixedly connected to one side surface of the sleeve ring.

[0017] On the other hand, the present invention also provides a process for treating associated petroleum gas, comprising the following steps:

[0018] The oil-associated gas is transported to the separation box, and the associated gas is preliminarily dehydrated by a dehydration device composed of a driving mechanism and a rotating mechanism, so that the wind propeller generates centrifugal force on the water particles in the associated gas under the drive, causing the water particles to gather toward the cavity wall, collide and combine into larger water droplets, and then slide down under the action of gravity, thereby achieving preliminary separation from the gas.

[0019] The associated gas after preliminary dehydration is introduced into the filter cylinder, and the filter disc is driven to rotate and move back and forth through the transmission mechanism. The impurities in the associated gas are filtered out by utilizing the characteristics of uniform contact and adsorption between the filter disc and the impurities in the associated gas. At the same time, the self-cleaning of the filter disc is achieved through the collision between the filter disc and the elastic impact block.

[0020] The filtered associated gas enters the separation chamber through the connecting pipe. Under the action of the translation and rotation mechanism and the oil and gas removal mechanism, the oil in the associated gas is effectively attached to the "V"-shaped plate, and the final oil and gas separation is achieved with the help of the shaking of the elastic telescopic parts and the confluence of the "L"-shaped plate.

[0021] The present invention provides a petroleum associated gas processing equipment. When the associated gas enters the separation box, the paddle can generate centrifugal force on the water particles in the associated gas under the coordinated operation of the driving mechanism and the rotating mechanism, so that the water particles continue to gather toward the cavity wall and collide and combine with each other to form larger water droplets, which slide downward under the action of gravity, thereby achieving separation from the gas and greatly improving the separation efficiency of water and gas.

[0022] The present invention provides a petroleum associated gas processing equipment, which can drive the filter disc to rotate and filter impurities in the associated gas entering the filter cylinder by setting a transmission mechanism. The continuously rotating filter disc can evenly adsorb impurities in the associated gas, avoiding the situation where some impurities are missed and not processed due to local uneven contact, thereby significantly improving the filtering efficiency of associated gas impurities.

[0023] The present invention provides a petroleum associated gas processing equipment, which can effectively attach the oil in the associated gas to each "V"-shaped plate through the action of a translational rotation mechanism and an oil and gas removal mechanism after impurities in the associated gas are removed, and the attached oil components are converged on multiple "L"-shaped plates under the shaking of each elastic telescopic part, so as to achieve good oil and gas separation.

[0024] The present invention provides a petroleum associated gas processing equipment, which arranges an elastic impact block inside the filter cartridge, and can hit the surface of the elastic impact block back and forth when the filter disc moves, so that the elastic impact block produces elastic deformation, absorbs the impact energy to provide rebound force, and causes impurities attached to the filter disc to fall off after being hit, so that the filter disc can achieve a self-cleaning effect, thereby increasing the service life of the filter disc.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention provides a petroleum associated gas processing equipment, such as Figure 1-Figure 3As shown, the associated petroleum gas processing equipment includes: a supporting base 1, a separation box 2, a dehydration device 3, a connecting pipe 4, a filter cartridge 5, a device chamber 6, a filter device 7, a separation device 8 and a separation chamber 9. The supporting base 1 is used to support and stabilize the entire device. The separation box 2 is fixedly mounted on one side of the upper surface of the supporting base 1. A support frame plate is provided at the bottom of the separation box 2 for supporting and fixing the separation box 2. The associated petroleum gas can be dehydrated after entering the interior of the separation box 2 through the dehydration device 3. The dehydration device 3 can generate a certain inclined rotating wind direction, which can drive the associated gas to move upward. The associated gas can enter the filter cartridge 5 through the connecting pipe 4 for filtering after preliminary dehydration. The interior of the device chamber 6 is used to set the filter device 7. Under the action of the filter device 7, the impurities mixed in the associated petroleum gas can be blocked and filtered, and then a relatively clean associated gas can be obtained. The separation device 8 can perform secondary oil and gas separation on the filtered associated gas.

[0039] like Figure 1-Figure 3 As shown, one end of the top of the separation box 2 is connected with an air inlet pipe 21, and the bottom of one side of the separation box 2 is connected with a liquid discharge pipe 22, and a device bin 23 is fixedly installed on one side of the separation box 2. By opening the valve on the air inlet pipe 21, the associated gas can be transported to the interior of the separation box 2 for dehydration. After the associated gas is initially dehydrated, some water liquid will be produced. At this time, a certain weight of water will accumulate at the bottom of the inner cavity of the separation box 2. Since the bottom shape of the separation box 2 is semi-cylindrical, it is convenient for liquid to accumulate. By opening the valve on the liquid discharge pipe 22, the liquid accumulated at the bottom can be discharged outward. The device bin 23 is fixed on one side of the separation box 2, which is convenient for the dehydration device 3 to be set in the device bin 23 for protective installation.

[0040] like Figure 3-Figure 4 As shown, the dehydration device 3 includes a driving mechanism 31, a rotating mechanism 32, a conical rotating plate 33 and a paddle 34. The driving mechanism 31 is used to drive the rotating mechanism 32 to rotate, and the conical rotating plate 33 is fixedly sleeved on the driving mechanism 31. The paddle 34 is fixedly connected to the driving mechanism 31.

[0041] The driving mechanism 31 is used to drive the rotating mechanism 32. When the driving mechanism 31 is started, the wind paddle 34 can be driven to generate an inclination angle operation as a whole, and the wind paddle 34 rotates under the driving action of the rotating mechanism 32, so that the wind paddle 34 can be fully rotated at an inclination angle as a whole. The conical rotating plate 33 is in a conical shape and is used to be sleeved on the driving mechanism 31, so that the driving mechanism 31 can be effectively protected from rotation when it passes through the side wall of the separation box 2, thereby avoiding damage to the device. Since the wind paddle 34 is provided with four blades, the wind paddle 34 can generate complex airflow movement, and the centrifugal force generated by the rotation can make it easier for the small water droplets in the associated gas of the petroleum to be separated from the gas phase. At this time, the water droplets will be subjected to the centrifugal force and move to the edge of the wind paddle 34. At this time, the airflow forms a certain axial thrust while rotating, so that the gas and water droplets can achieve better stratification in the process of continuous advancement. In this dynamic environment, the small water droplets are more likely to gather and grow. When they grow to a certain extent, they will settle due to the action of gravity, which is convenient for better discharge, thereby improving the efficiency of dehydration of the associated gas of the petroleum.

[0042] The driving mechanism 31 includes a motor 1 311, a rotating wheel 1 312, a rotating wheel 2 313, a rotating belt 314, a rotating kit 315, and a rotating rod 316. The motor 1 311 is fixedly mounted on the outer wall of the device chamber 23, and the output end of the motor 1 311 is fixedly connected to the rotating wheel 1 312. One end of the rotating wheel 2 313 is rotatably mounted on the inner wall of the device chamber 23, and both the rotating wheel 1 312 and the rotating wheel 2 313 are wound and connected with the rotating belt 314. One end of the rotating kit 315 is fixedly mounted on the rotating wheel 1 312, and the other end is fixedly connected to the rotating rod 316. The rotating rod 316 is fixedly connected to the conical rotating plate 33, and one end of the rotating rod 316 penetrates the inner wall surface of the device chamber 23 and is fixedly connected to the paddle 34.

[0043] The driving mechanism 31 as a whole can generate a driving effect. The motor 1 311 is fixed on the side wall of the device bin 23, so that one end of it is embedded in the surface and the output end is fixedly installed with the rotating wheel 1 312. The size of the rotating wheel 1 312 is the same as that of the rotating wheel 2 313, and both are connected by winding with the rotating belt 314. When the motor 1 311 is started to drive the rotating wheel 1 312 to rotate, since the rotating wheel 2 313 is integrally rotated and installed on the device bin 23, at this time, the rotating wheel 1 312 and the rotating wheel 2 313 can be driven to rotate synchronously under the sliding winding of the rotating belt 314. The rotating kit 315 is fixed on the rotating wheel 1 312 and rotates with the rotating wheel 1 312. And one end of the rotating kit 315 is fixedly connected with the rotating rod 316. When the motor 1 311 drives the rotating wheel 1 312 to rotate, the rotating rod 316 rotates as a whole, and the rotating kit 315 can be fully tilted and rotated in the special limited situation to meet the appropriate operation requirements.

[0044] The rotating mechanism 32 includes a connecting rod 321, a support plate 322, a gear 1 323, and a gear 2 324. One end of the connecting rod 321 is fixedly mounted on the surface of the rotating wheel 2 313, and the other end penetrates the surface of the support plate 322 and is rotatably mounted on the inner wall of the device bin 23. The support plate 322 is fixedly mounted on the top of the inner cavity of the device bin 23, and the surface of the support plate 322 is provided with a through hole that is movably interlaced with the rotating rod 316. The gear 1 323 is fixedly mounted on the connecting rod 321. The gear 2 324 is fixedly mounted on the surface of the rotating rod 316 and meshes with the gear 1 323.

[0045] The connecting rod 321 is fixedly connected to the second wheel 313 through one end, and the other end passes through the support plate 322 and the gear 1 323 and is rotatably installed on the device compartment 23, so that the second wheel 313 drives the whole wheel 1 312 to rotate under the connection drive of the wheel 1 312, and the support plate 322 is used to support and limit the wheel 1 312, and the gear 1 323 is fixedly connected to the wheel 1 312. Therefore, the gear 1 323 can be driven to rotate under the action of the connecting rod 321, and the gear 2 324 meshing with the gear 1 323 can rotate synchronously, and the gear 2 324 is fixedly connected to the rotating rod 316, which will eventually drive the wind paddle 34 fixedly installed on one end of the rotating rod 316 to rotate, so that the entire rotating mechanism 32 can drive the wind paddle 34 to rotate.

[0046] One end of the connecting pipe 4 is connected to the separation box 2, and the other end is fixedly mounted with a filter cartridge 5. A device chamber 6 is fixedly mounted on one side of the filter cartridge 5.

[0047] The connecting pipe 4 is used to connect the separation box 2 and the filter cartridge 5, so that the petroleum associated gas that has been dehydrated inside the separation box 2 can enter the filter cartridge 5. One end of the filter cartridge 5 is cylindrical, and the other end is conical, which is convenient for the associated gas to flow in. The bottom of the filter cartridge 5 is equipped with a discharge pipe for discharging, and the impurities in the petroleum associated gas filtered by the filter cartridge 5 can be discharged through the discharge pipe. A collecting bin is provided at the bottom of the discharge pipe to collect impurities discharged from the discharge pipe. A cleaning door is provided on the collection bin to facilitate entering the collection bin to clean the impurities. The entire filter cartridge 5 is supported and installed by an externally mounted bracket, which can better achieve a connecting installation between the filter cartridge 5 and the device chamber 6. The device chamber 6 is used to protect the device. Door panels are provided on both sides of the outside of the device chamber 6. When the device needs to be maintained later, the door panels can be removed.

[0048] like Figure 3 and Figure 5As shown, the filter device 7 includes a transmission mechanism 71 and a rotary propulsion mechanism 72. The transmission mechanism 71 is arranged inside the device chamber 6 and is used to drive the rotary propulsion mechanism 72 to move forward and backward and rotate. One end of the rotary propulsion mechanism 72 is movably connected in the filter cartridge 5 for filtering the associated gas of petroleum.

[0049] The filter device 7 is used as a whole to filter impurities from the associated gas. The transmission mechanism 71 is used to drive the rotary propulsion mechanism 72. The transmission mechanism 71 cooperates with the rotary propulsion mechanism 72 to absorb and filter the impurities in the associated gas inside the filter cylinder 5. The adsorbed impurities can be knocked off by the operation of the transmission mechanism 71 and the rotary propulsion mechanism 72, so that the associated gas can be continuously and smoothly filtered, avoiding the interruption of filtering or the reduction of filtering effect due to the accumulation of impurities.

[0050] The transmission mechanism 71 includes a motor 2 711, a pulley 1 712, a pulley 2 713, a transmission belt 714, a first cylindrical gear 715, a second cylindrical gear 716 and a gear 3 717. The motor 2 711 is fixedly mounted on the inner wall of the device chamber 6. One end of the pulley 1 712 is fixedly connected to the output end of the motor 2 711, and the other end is fixedly connected to the second cylindrical gear 716. The transmission belt 714 is movably wound around the outer surfaces of the pulley 1 712 and the pulley 2 713. One end of the first cylindrical gear 715 is rotatably connected to a fixed plate, which is mounted on the top of the inner cavity of the device chamber 6. The first cylindrical gear 715 and the second cylindrical gear 716 are both meshed with the gear 3 717.

[0051] By starting the second motor 711, the pulley 1 712 can be driven to rotate, and the pulley 1 712 drives the pulley 2 713 to rotate through the transmission belt 714. At the same time, the pulley 1 712 drives the second cylindrical gear 716 to rotate, and the second cylindrical gear 716 drives the first cylindrical gear 715 to rotate through the gear 3 717.

[0052] The rotary propulsion mechanism 72 includes two telescopic rods 721, a "U"-shaped push rod 722, a filter disc 723, a support sleeve 724, a propulsion rod 725 and a screw 726. One end of the two telescopic rods 721 is fixedly mounted on the second pulley 713, and the other end is movably connected to the "U"-shaped push rod 722. One end of the filter disc 723 is fixedly connected to the "U"-shaped push rod 722, and the other end is movable inside the filter cartridge 5. The support sleeve 724 is sleeved on the outer surface of the propulsion rod 725 and fixedly mounted on the second pulley 713. One end of the propulsion rod 725 is fixedly connected to the "U"-shaped push rod 722, and the other end is screwed to the screw 726. The screw 726 passes through the second pulley 713 and is fixedly mounted on the first cylindrical gear 715.

[0053] Since the two telescopic rods 721 are fixedly mounted on the second pulley 713, and the other ends of the two telescopic rods 721 support and mount the filter disc 723, when the second pulley 713 rotates, the filter disc 723 will be driven to rotate as a whole. One end of the filter disc 723 is located at one end of the inner cavity of the filter cartridge 5 and is limitedly mounted, which can provide space for the filter disc 723 to move as a whole. The support sleeve 724 is used to support the push rod 725, one end of which is mounted on the "U"-shaped push rod 722 and the other end is mounted on the second pulley 713. One end of the screw rod 726 passes through the second pulley 713 and is screwed to the push rod 725, and the other end generates a rotational force under the drive of the first cylindrical gear 715. Therefore, when the motor 2 711 rotates forward, it can drive the filter plate 723 to rotate while allowing the push rod 725 to move, and allow the "U"-shaped push rod 722 to be able to extend and retract through the telescopic rod 721, thereby producing a limiting effect, so that the filter plate 723 can rotate while being able to move inside the filter tube 5. Similarly, when the motor 2 711 rotates reversely, it can drive the filter plate 723 to reset.

[0054] A control electrical box is installed on the upper surface of the mounting base 1. By setting parameters of the control terminal, the control terminal can send a command signal to the motor 2 711, thereby realizing intelligent regulation of the operation mode of the motor 2 711. When the motor 2 711 receives the command, it automatically enters an intermittent forward and reverse state, thereby satisfying the rotation and forward and backward displacement of the filter disc 723 itself, so as to improve the working efficiency of the filter disc 723.

[0055] like Figure 6-Figure 7 As shown, the separation device 8 includes a translation and rotation mechanism 81, an oil and gas removal mechanism 82 and a limiting column 83. The translation and rotation mechanism 81 is used to drive the oil and gas removal mechanism 82 to translate and rotate. The limiting column 83 is movably connected to the translation and rotation mechanism 81. The translation and rotation mechanism 81 can cooperate with the transmission mechanism 71 to produce a state of rotation and self-movement back and forth. At this time, the translation and rotation mechanism 81 will drive the oil and gas removal mechanism 82 to rotate back and forth as a whole, and can separate and process part of the oil in the associated gas. The limiting column 83 is used to limit the driving operation of the translation and rotation mechanism 81.

[0056] The translation and rotation mechanism 81 includes a translation rod 811, a sleeve column 812, a limit stop block 813, and a limit sleeve rod 814. One end of the translation rod 811 is fixedly connected to the gear three 717, and the other end is fixedly connected to the sleeve column 812. The translation rod 811 is movably connected to the fixed plate. The limit stop block 813 is fixedly installed on the top of the inner cavity of the device chamber 6, and the surface of the sleeve column 812 is provided with a groove that movably contacts the limit stop block 813. The limit sleeve rod 814 is fixedly connected to the sleeve column 812.

[0057] The translation rod 811 is fixedly connected to the gear three 717 and supported and installed under the fixed plate, so that after the gear three 717 is driven to rotate by the second cylindrical gear 716, it will synchronously drive the sleeve column 812 to rotate as a whole. Since the limit stop block 813 is fixedly installed and the bottom end of the limit stop block 813 is located in the groove opened on the surface of the sleeve column 812, it can limit the sleeve column 812 as a whole, so that the sleeve column 812 can rotate and move back and forth under the action of the limit stop block 813. At the same time, the gear three 717 can be located between the first cylindrical gear 715 and the second cylindrical gear 716 and move back and forth, thereby synchronously driving the limit sleeve rod 814 to operate.

[0058] The oil and gas removal mechanism 82 includes four elastic telescopic parts 821, two circular plates 822, four "V"-shaped plates 823, and multiple "L"-shaped plates 824. The four elastic telescopic parts 821 are respectively fixedly mounted on the surfaces on both sides of the limiting sleeve 814. The two circular plates 822 are respectively fixedly connected to each elastic telescopic part 821, and the two circular plates 822 are both sleeved on the limiting sleeve 814. Both ends of each "V"-shaped plate 823 are fixedly connected between the two circular plates 822. Each "L"-shaped plate 824 is installed in an array on the surface of each "V"-shaped plate 823. One end of the limiting sleeve 814 is provided with a card slot movably connected to the limiting column 83. The surface of the limiting column 83 is installed with four card strips that are limitedly connected to the limiting sleeve 814.

[0059] After the elastic telescopic member 821 is fixedly connected to the limiting sleeve rod 814 through one end, the two elastic telescopic members 821 are effectively connected by fixing the other end of each elastic telescopic member 821, and the two annular plates 822 can shake under the action of each elastic telescopic member 821. The overall shape of the four "V"-shaped plates 823 is "V"-shaped, so that both ends are connected and fixed between the two annular plates 822, so that each "V"-shaped plate 823 can be driven to shake synchronously when the two annular plates 822 rotate and shake. The multiple "L"-shaped plates 824 located on the "V"-shaped plate 823 will attach the separated oil to the "V"-shaped plate 823 after the "V"-shaped plate 823 contacts the oil, thereby improving the oil and gas separation effect. The multiple "L"-shaped plates 824 cleverly realize the confluence of the separated oil liquid, and combined with the shaking effect under the multiple elastic telescopic members 821, it can ensure that the oil liquid flows out smoothly and quickly downward.

[0060] The outer surface of the limiting column 83 is provided with four clamping strips, and one end of the limiting sleeve rod 814 is provided with a plurality of clamping strips and clamping slots movably connected to the limiting column 83, so that the limiting sleeve rod 814 can achieve a limiting effect when it is sleeved on the surface of the limiting column 83. Since the limiting column 83 is rotatably installed, the overall rotation stability of the limiting sleeve rod 814 can be improved.

[0061] The separation chamber 9 is fixedly mounted on the other side of the upper surface of the mounting base 1. A connecting pipe 91 is connected through one end of the bottom side of the separation chamber 9, and the other end of the connecting pipe 91 is fixedly connected to the bottom of the surface of the filter cartridge 5. An air outlet pipe 92 is connected through the top of the separation chamber 9, and a liquid outlet pipe 93 is connected through the bottom. The limiting sleeve rod 814 penetrates the surface of the separation chamber 9 and is movably connected to the limiting column 83. The other end of the limiting column 83 is rotatably mounted on the inner wall of the separation chamber 9.

[0062] The limiting sleeve rod 814 is supported and installed by penetrating the surface of the separation chamber 9 and the oil and gas removal mechanism 82, and can drive the oil and gas removal mechanism 82 to operate. After the associated gas passes through the internal filtration of the filter cartridge 5, it will be transported to the internal oil and gas separation of the separation chamber 9 through the connecting pipe 91. The separated associated gas will eventually be discharged through the gas outlet pipe 92, and the separated petroleum liquid will flow out through the liquid outlet pipe 93. The two sides of the outside of the separation chamber 9 are installed by frame plates to support its stable operation.

[0063] like Figure 8 As shown, a sleeve ring 10 is fixedly installed on the inner wall of the filter cartridge 5, and an elastic impact block 11 is fixedly connected to one side surface of the sleeve ring 10. The sleeve ring 10 is installed on one side of the inner cavity of the filter cartridge 5. The sleeve ring 10 is in the shape of a circular ring sleeve plate as a whole. A space groove for impurities to fall is provided at the bottom of the sleeve plate, so that the filter disc 723 can be located in the sleeve ring 10 and move back and forth. By installing an elastic impact block 11 on the outer surface of the sleeve ring 10, the elastic impact block 11 has a certain elasticity, and the material can be an elastic material such as rubber, polyurethane, etc. When the filter disc 723 hits the elastic impact block 11, the elastic impact block 11 can produce elastic deformation, absorb the impact energy, and provide rebound force, thereby hitting and bouncing the impurities accumulated on the filter disc 723, so that the filter disc 723 reaches a self-cleaning state.

[0064] This embodiment can efficiently dehydrate the associated gas by using the dehydration device 3, which can improve the separation of water vapor in the associated gas. At the same time, the filter device 7 can achieve automatic rotation of the filter disc 723, thereby evenly contacting the impurities in the associated gas and improving the filtering effect. The filter disc 723 is cleaned by impacting it, which can increase the service life of the device. Finally, the separation device 8 and the filter device 7 are used to cooperate to separate the oil and gas in the associated gas, thereby improving the working efficiency of the associated gas equipment.

[0065] like Fig. 9 As shown, the present invention also discloses a petroleum associated gas processing process, which specifically includes the following steps:

[0066] The petroleum-associated gas enters the interior of the separation box 2 through the air inlet pipe 21 .

[0067] The motor 1 311 is started, and the motor 1 311 drives the wheel 1 312 and the wheel 2 313 to rotate synchronously, so that the rotating kit 315 connected to the wheel 1 312 rotates. When the rotating kit 315 rotates, it drives the rotating rod 316 located inside the support plate 322 to rotate in an inclined direction, thereby rotating the wind blade 34 connected to the rotating rod 316. When the wind blade 34 rotates, a vortex wind with centrifugal force is generated. Under the action of the centrifugal force, the water in the oil-associated gas is gathered to the edge of the separation box 2, so as to separate the water in the oil-associated gas.

[0068] In the above process, the second rotating wheel 313 drives the first gear 323 to rotate through the connecting rod 321. When the first gear 323 rotates, it meshes with the second gear 324 sleeved on the outer wall of the rotating rod 316 to improve the rotation stability of the paddle 34.

[0069] After the initial dehydration treatment, the associated gas enters the filter cartridge 5 through the connecting pipe 4, and the motor 2 711 is started. The motor 2 711 drives the pulley 1 712 to rotate. The pulley 1 712 drives the pulley 2 713 to rotate through the transmission belt 714. The pulley 1 712 and the pulley 2 713 respectively drive the first cylindrical gear 715 and the second cylindrical gear 716 to rotate, which drives the gear 3 717 located between the pulley 1 712 and the pulley 2 713 to rotate. The rotation of the first cylindrical gear 715 drives the screw rod 726 to rotate at the same time. Since the screw rod 726 is screwed to the propulsion rod 7 25, so that the screw rod 726 in the rotating process pushes the push rod 725 to move, and the push rod 725 pushes the "U"-shaped push rod 722 to move, and the "U"-shaped push rod 722 drives the filter plate 723 located inside the filter cylinder 5 to rotate and translate back and forth under the support of the two telescopic rods 721. When moving, the filter plate 723 can hit the elastic impact block 11, so that impurities on the filter plate 723 are hit and fall off, and when the filter plate 723 rotates, the impurities will be evenly contacted on the filter plate 723, so as to achieve a better filtering effect.

[0070] The associated gas after impurities are filtered out will enter the separation chamber 9 through the connecting pipe 91 for the next step of oil and gas separation. Since the translation rod 811 is driven to rotate by the gear three 717, and the sleeve column 812 is limited by the limiting block 813, a self-rotating and forward and backward moving operation mode is formed, which can drive the multiple "V"-shaped plates 823 located between the two circular plates 822 to rotate, and then effectively adhere to the oil in the associated gas. When the limiting sleeve rod 814 moves back and forth, the attached oil can flow downward by shaking under the collection of the "L"-shaped plate 824. Finally, the associated gas after the treatment will be discharged into the conveying pipeline through the outlet pipe 92.

[0071] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, i.e., they may be located in one place, or they may be distributed on multiple network units.
