Description

Technical Field

[0001] This utility model relates to the field of oil and gas treatment technology, and more specifically, to an oil and gas separator. Background Technology

[0002] An oil-gas separator is a device used to separate oil from gas and is widely used in the petroleum, natural gas, chemical, and other industrial fields. Its main function is to effectively separate oil mist, liquid oil droplets, or other impurities from gas, thereby ensuring gas quality, protecting the normal operation of downstream equipment, and improving gas processing efficiency.

[0003] In existing technologies, impurities or large particles that may exist in oil and gas cannot be effectively removed, which can easily affect the efficiency of subsequent oil and gas separation. If solid impurities or large particles that may exist in oil and gas are not effectively filtered, they will enter the interior of the separation tank components, causing wear or blockage of the equipment and reducing its service life. Since impurities cannot be removed, pollutants in the oil and gas separation process may interfere with the separation effect, resulting in impure oil and gas after separation, which will affect subsequent use or treatment.

[0004] Backflow may occur during the oil-gas separation process, which can reduce the efficiency of the system and may lead to oil-gas mixing or contamination. Leaks may also occur during the oil-gas separation process, affecting separation efficiency or posing safety hazards, especially when dealing with flammable and explosive gases, where leaks may cause danger. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides an oil-gas separator to solve the technical problems mentioned in the background art, such as the inability to effectively remove impurities or large particles and the possible backflow phenomenon of oil and gas during the separation process.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an oil-gas separator, comprising a separator tank assembly, an additive filtration mechanism, a one-way sealing mechanism, and a sealing auxiliary mechanism. The additive filtration mechanism includes an additive pipe, a filter plate, a filter tube, an extension pipe, and a connecting plate. One end of the extension pipe is fixedly installed at the top end of the separator tank assembly. The connecting plate is installed at the outer end of the additive pipe and the extension pipe. The filter tube is installed between the additive pipe and the extension pipe. The filter plate is installed inside the filter tube. The one-way sealing mechanism includes a one-way pipe, a guide rod, a movable frame, a guide frame, a tension spring, a mating plate, and a one-way plate. The guide frame is fixedly installed on the inner wall of the one-way pipe. The guide rod is slidably installed on the guide frame. The movable frame is directionally slidably installed on the inner wall of the one-way pipe. The tension spring is installed between the movable frame and the guide frame. The mating plate is fixedly installed on the inner wall of the one-way pipe. The one-way plate is fixedly installed at one end of the guide rod, and the one-way plate and the mating plate are configured for one-way sealing.

[0009] The present invention is further configured such that the sealing auxiliary mechanism includes a dredging plate, a dredging rod, a top rod, and a one-way spiral blade. The dredging plate is fixedly installed inside the one-way pipe. Multiple sets of dredging rods are installed on the bottom end face of the one-way plate, the top rod is installed on the top end of the one-way plate, and the one-way spiral blade is installed on the inner wall of the one-way pipe. The top rod can push against one end of the one-way spiral blade to open the one-way spiral blade.

[0010] The present invention is further configured such that a fixing plate is installed at the top end of the separation tank assembly, and multiple sets of fixing plates are provided. An exhaust pipe is installed through the fixing plate. The exhaust pipe can effectively remove the separated gas, improve the efficiency of the separation process, and ensure that the gas does not remain in the system.

[0011] The present invention is further configured such that one end of the gas outlet pipe is fixedly connected to one end of the one-way pipe, and the insertion pipe extends through and into the fixed plate. The one-way pipe, the guide rod, and the moving frame ensure the unidirectionality of the oil and gas flow direction and prevent fluid backflow.

[0012] The present invention is further provided that connecting plates are installed at both ends of the filter tube, and the connecting plates are fixedly connected to the connecting plate. The setting of the connecting plates facilitates the stable connection of the filter tube.

[0013] The present invention is further configured such that there are two sets of gas outlet pipes, and the two sets of gas outlet pipes are symmetrically installed on both sides of the top end of the separator assembly. By designing multiple sets of gas outlet pipes, the gas emission channels after oil-gas separation can be effectively increased, the gas emission resistance can be reduced, the exhaust efficiency can be improved, and the possible risk of blockage can be reduced.

[0014] The present invention is further configured such that an external plate is installed at one end of the one-way pipe, and the external plate is connected in conjunction with an external gas processing device. The design of the external plate enables the oil-gas separator to cooperate with the external gas processing device to achieve further processing or emission of gas, thereby improving the overall processing capacity of the system.

[0015] The present invention is further configured such that a base is symmetrically installed at the bottom end of the separation tank assembly, and the bottom end of the base contacts the ground for support. The base provides stable support for the entire device, preventing displacement or damage caused by vibration or external impact.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an oil-gas separator with the following advantages:

[0018] This utility model is equipped with an additive filtration mechanism. The additive filtration mechanism effectively removes impurities, solid particles, or contaminants from oil and gas through filter pipes and filter plates, ensuring that the oil and gas fluid entering the separator is purer and preventing these impurities from interfering with the oil and gas separation process. The design of the filter plates and filter pipes ensures that the oil and gas undergo sufficient filtration before entering the separator, reducing the wear or blockage of other components after solid particles enter the system, and ensuring the long-term stable operation of the separation system.

[0019] This invention features a one-way sealing mechanism. The one-way sealing mechanism utilizes the design of a one-way plate and a mating plate to ensure the one-way flow direction of oil and gas, preventing backflow during the separation process. If backflow occurs, it may lead to unstable separation effect or even contaminate the unseparated oil and gas. Therefore, the one-way seal can effectively ensure the normal operation of the system. Through the combination of guide rod, tension spring and one-way plate, it can ensure that the gas flow inside the separator is in the expected direction, prevent gas leakage or poor flow, improve the sealing effect and ensure the stability of the internal pressure of the system.

[0020] This utility model is equipped with a sealing auxiliary mechanism. The unblocking plate and unblocking rod in the sealing auxiliary mechanism can automatically unblock when the one-way sealing mechanism is blocked or the sealing effect is poor, so as to maintain the smoothness of the system. In particular, the design of the one-way spiral blade can be opened by the action of the top rod when it encounters a blockage, clearing obstacles that may hinder the flow of oil and gas, and reducing maintenance difficulty.

[0030] Please see Figures 1-5An oil-gas separator includes a separator tank assembly 1, an additive filtration mechanism, a one-way sealing mechanism, and a sealing auxiliary mechanism. The additive filtration mechanism includes an additive pipe 2, a filter plate 3, a filter pipe 4, an extension pipe 5, and a connecting plate 6. One end of the extension pipe 5 is fixedly installed through and at the top of the separator tank assembly 1. The connecting plate 6 is installed at the outer end of the additive pipe 2 and the extension pipe 5. The filter pipe 4 is installed between the additive pipe 2 and the extension pipe 5. The filter plate 3 is installed inside the filter pipe 4. The one-way sealing mechanism includes a one-way pipe 7 and a guide pipe... The guide rod 8, the movable frame 9, the guide frame 10, the tension spring 11, the mating plate 12, and the one-way plate 13 are provided. The guide frame 10 is fixedly installed on the inner wall of the one-way pipe 7. The guide rod 8 is slidably installed on the guide frame 10. The movable frame 9 is directionally slidably installed on the inner wall of the one-way pipe 7. The tension spring 11 is installed between the movable frame 9 and the guide frame 10. The mating plate 12 is fixedly installed on the inner wall of the one-way pipe 7. The one-way plate 13 is fixedly installed on one end of the guide rod 8, and the one-way plate 13 and the mating plate 12 are configured for one-way sealing.

[0031] In this embodiment, when the oil-gas mixture enters the separator, it first enters the interior of the separator tank assembly 1 through the insertion pipe 5. One end of the insertion pipe 5 is fixed to the top of the separator tank assembly 1 and passes through it. The oil-gas mixture flows into the addition pipe 2. At this time, the oil and gas in the oil-gas mixture begin to be separated through a filtration process. The filter pipe 4 is installed between the addition pipe 2 and the insertion pipe 5. The oil-gas mixture needs to pass through the pores of the filter pipe 4. The filter plate 3 is installed inside the filter pipe 4. The gas enters the gas separation channel through the one-way pipe 7. The guide frame 10 is fixed to the inner wall of the one-way pipe 7 and plays a role in guiding the gas flow. The guide rod 8 slides within the guide frame 10, providing a smooth path for gas flow. The movable frame 9 is directionally slidably installed on the inner wall of the one-way tube 7. It adjusts the flow direction of the airflow by sliding. The tension spring 11 is installed between the movable frame 9 and the guide frame 10, providing elasticity to help the movable frame 9 return to its original position and ensure sealing performance. The one-way plate 13 is installed at one end of the guide rod 8. When the gas flows, the one-way plate 13 can perform one-way sealing by cooperating with the mating plate 12, so that the gas can only flow in one direction and prevent backflow. The mating plate 12 is fixedly installed on the inner wall of the one-way tube 7 and forms a sealing fit with the one-way plate 13.

[0032] The sealing auxiliary mechanism includes a dredging plate 14, a dredging rod 15, a push rod 16, and a one-way spiral blade 17. The dredging mechanism is fixedly installed inside the one-way pipe 7. Multiple sets of dredging rods 15 are installed on the bottom end face of the one-way plate 13, the push rod 16 is installed on the top end of the one-way plate 13, and the one-way spiral blade 17 is installed on the inner wall of the one-way pipe 7. The push rod 16 can push against one end of the one-way spiral blade 17 to open the one-way spiral blade 17.

[0033] When the sealing auxiliary mechanism is required to operate, the unblocking plate 14 is fixedly installed inside the one-way pipe 7 to unblock the airflow and prevent impurities from accumulating and affecting the normal operation of the sealing mechanism. Multiple sets of unblocking rods 15 are installed on the bottom end face of the one-way plate 13. The function of the unblocking rods 15 is to clean the area below the one-way plate 13 that may be blocked, ensuring that the sealing part is unobstructed. The push rod 16 is installed at the top end of the one-way plate 13. Through the action of the push rod 16, it can push against the one-way spiral blade 17, causing the spiral blade to extend or relax, helping to maintain the smooth flow of airflow. The one-way spiral blade 17 is installed on the inner wall of the one-way pipe 7. Through the design of the spiral blade, it can guide the airflow and reduce the airflow turbulence. The push rod 16 adjusts the airflow direction by contacting the spiral blade, ensuring that the sealing effect of the oil-gas separator is not affected.

[0034] Please see Figures 1-5 As a supplementary embodiment of an oil-gas separator with added filtration mechanism, one-way sealing mechanism and sealing auxiliary mechanism: A fixing plate 18 is installed at the top end of the separator tank assembly 1. Multiple sets of fixing plates 18 are provided, and an outlet pipe 19 is installed through the fixing plate 18. One end of the outlet pipe 19 is fixedly connected to one end of the one-way pipe 7. An extension pipe 5 extends through the fixing plate 18. Connecting plates 20 are installed at both ends of the filter pipe 4, and the connecting plates 20 are fixedly connected to the connecting plate 6. Two sets of outlet pipes 19 are provided, and the two sets of outlet pipes 19 are symmetrically installed on both sides of the top end of the separator tank assembly 1. An external connecting plate 21 is installed at one end of the one-way pipe 7, and the external connecting plate 21 is connected to the external gas treatment equipment. A base 22 is symmetrically installed at the bottom end of the separator tank assembly 1, and the bottom end of the base 22 is in contact with the ground for support.

[0035] More specifically, the oil-gas mixture enters the separation tank assembly 1 of the oil-gas separator through the inlet pipe 5. The design of the inlet pipe 5 ensures the smooth entry of the oil-gas mixture. The mixture flows into the oil-gas separator through the addition pipe 2 and undergoes preliminary impurity removal through the filter pipe 4 and filter plate 3, ensuring that the gas is cleaner when it enters the downstream stage. After filtration, the separation of oil and gas begins. The gas part enters the one-way pipe 7 through the one-way sealing mechanism, while the oil part is separated through the oil discharge system. The gas enters the gas outlet through the one-way pipe 7. The one-way sealing mechanism ensures that the gas can only flow in one direction, avoiding reverse flow. The cooperation of the guide rod 8, the moving frame 9, and the one-way plate 13 ensures precise control of the gas flow direction. The sealing auxiliary mechanism, through the action of the unblocking plate 14, the unblocking rod 15, and the top rod 16, keeps the sealing area unobstructed and maintains the smooth flow of air inside the oil-gas separator, avoiding any impurities from affecting the sealing mechanism.

[0036] In summary, during the use or operation of the overall equipment: when a filtration mechanism is required, impurities in the oil-gas mixture are removed through filtration to improve the oil-gas separation effect. When the oil-gas mixture enters the separator, it first enters the interior of the separation tank assembly 1 through the insertion pipe 5. One end of the insertion pipe 5 is fixed to the top of the separation tank assembly 1 and passes through it. The oil-gas mixture flows into the addition pipe 2. At this time, the oil and gas in the oil-gas mixture begin to be separated through the filtration process. The filter pipe 4 is installed between the addition pipe 2 and the insertion pipe 5. The oil-gas mixture needs to pass through the pores of the filter pipe 4. The filter plate 3 is installed inside the filter pipe 4. The function of these two is to block larger particulate impurities and ensure that only a relatively clean oil-gas mixture can pass through to enter the subsequent processing stage.

[0037] When the one-way sealing mechanism is required, it ensures the one-way flow of gas during the oil-gas separation process and guarantees the sealing effect. After the oil-gas mixture undergoes preliminary separation, the gas enters the gas separation channel through the one-way pipe 7. The guide frame 10 is fixed to the inner wall of the one-way pipe 7 and guides the gas flow. The guide rod 8 slides inside the guide frame 10 to provide a smooth path for the gas flow. The movable frame 9 is directionally slidably installed on the inner wall of the one-way pipe 7. It adjusts the flow direction of the airflow by sliding. The tension spring 11 is installed between the movable frame 9 and the guide frame 10 to provide elasticity and help the movable frame 9 return to its original position to ensure sealing performance. The one-way plate 13 is installed at one end of the guide rod 8. When the gas flows, the one-way plate 13 can perform one-way sealing by cooperating with the mating plate 12, so that the gas can only flow in one direction and prevent backflow. The mating plate 12 is fixedly installed on the inner wall of the one-way pipe 7 and forms a sealing fit with the one-way plate 13.

[0038] When the sealing auxiliary mechanism is required to operate, the unblocking plate 14 is fixedly installed inside the one-way pipe 7 to unblock the airflow and prevent impurities from accumulating and affecting the normal operation of the sealing mechanism. Multiple sets of unblocking rods 15 are installed on the bottom end face of the one-way plate 13. The function of the unblocking rods 15 is to clean the area below the one-way plate 13 that may be blocked, ensuring that the sealing part is unobstructed. The push rod 16 is installed at the top end of the one-way plate 13. Through the action of the push rod 16, it can push against the one-way spiral blade 17, causing the spiral blade to extend or relax, helping to maintain the smooth flow of airflow. The one-way spiral blade 17 is installed on the inner wall of the one-way pipe 7. Through the design of the spiral blade, it can guide the airflow and reduce the airflow turbulence. The push rod 16 adjusts the airflow direction by contacting the spiral blade, ensuring that the sealing effect of the oil-gas separator is not affected.

[0039] The oil-gas mixture enters the separation tank assembly 1 of the oil-gas separator through the inlet pipe 5. The design of the inlet pipe 5 ensures the smooth entry of the oil-gas mixture. The mixture flows into the oil-gas separator through the addition pipe 2 and undergoes preliminary impurity removal through the filter pipe 4 and filter plate 3, ensuring that the gas is cleaner when it enters the downstream stage. After filtration, the separation of oil and gas begins. The gas part enters the one-way pipe 7 through the one-way sealing mechanism, while the oil part is separated through the oil discharge system. The gas enters the gas outlet through the one-way pipe 7. The one-way sealing mechanism ensures that the gas can only flow in one direction, avoiding reverse flow. The cooperation of the guide rod 8, the moving frame 9, and the one-way plate 13 ensures precise control of the gas flow direction. The sealing auxiliary mechanism, through the action of the unblocking plate 14, the unblocking rod 15, and the top rod 16, keeps the sealing area unobstructed and maintains the smooth flow of air inside the oil-gas separator, avoiding any impurities from affecting the sealing mechanism.
