Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery and treatment technology, and specifically to an oil and gas recovery combined membrane treatment device for an oil and gas recovery and treatment apparatus. Background Technology

[0002] An oil and gas recovery unit is a device used to collect and process oil and gas generated during industrial production. Through technologies such as adsorption, condensation, or membrane separation, it converts the oil and gas into reusable liquid fuels or gases, thereby reducing environmental pollution and energy waste. Membrane separation technology primarily utilizes the selective permeability of polymer membranes to separate oil and gas from air. Membrane separation technology has advantages such as good separation efficiency, low energy consumption, and simple operation.

[0003] A search revealed that application CN221637731U discloses an oil and gas recovery membrane assembly for an oil and gas recovery treatment device. This assembly, when the mixed gas enters the recovery membrane through the main body, drives two pistons, one moving closer to the cylinder and the other moving away from it. The side frame where the piston moving away from the cylinder is located is under negative pressure. Therefore, the oil and gas in the mixed gas can fully pass through the recovery membrane and enter the side frame under the pressure, and then be discharged through the oil drain pipe, thereby improving the oil and gas recovery effect and reducing oil and gas waste.

[0004] However, there are still some defects and shortcomings that need to be optimized. The specific defects and shortcomings are as follows: The pressure supply part of the oil and gas recovery membrane module of the oil and gas recovery treatment device mainly achieves mechanical movement pressure supply through the action of the drive part. Not only is the structure complex and the maintenance is relatively cumbersome when a fault occurs, but it can also only supply pressure on one side, resulting in low utilization of the side frame. Therefore, it is necessary to design an oil and gas recovery combined membrane treatment device to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to provide an oil and gas recovery combined membrane treatment device for an oil and gas recovery treatment device. Through the design of the automatic pressure supply component, the structure is not only more reasonable and simple, but also external to the oil and gas negative pressure chamber, which facilitates fault maintenance. It can also achieve all-round pressure supply, thereby maximizing the utilization rate of the oil and gas negative pressure chamber, thus effectively solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An oil and gas recovery combined membrane treatment device for an oil and gas recovery treatment apparatus includes an oil and gas negative pressure chamber, an oil and gas recovery membrane module, and an automatic pressure supply module. The oil and gas recovery membrane module is installed through the center of the interior of the oil and gas negative pressure chamber. The automatic pressure supply module is provided on the outer surface of the oil and gas negative pressure chamber. The automatic pressure supply module is composed of a gas path system and a negative pressure pump body. The gas path system includes side-mounted negative pressure pipelines symmetrically distributed on both sides of the oil and gas negative pressure chamber. The side-mounted negative pressure pipelines on both sides of the oil and gas negative pressure chamber are connected through a central negative pressure pipeline. The side-mounted negative pressure pipelines and the oil and gas negative pressure chamber are connected through a chamber pipeline. The air inlet on the negative pressure pump body and the central negative pressure pipeline are connected through a pump pipeline.

[0008] As a preferred embodiment of this utility model, the oil and gas recovery membrane assembly includes a main recovery membrane shell located inside the oil and gas negative pressure chamber, an upper membrane shell cover is spirally installed at the top of the main recovery membrane shell, and a lower membrane shell cover is fixedly installed at the bottom of the main recovery membrane shell.

[0009] As a preferred embodiment of this utility model, a number of one-way valves arranged in a ring are fixedly installed on the outer surface of the main recovery membrane shell from top to bottom, the recovery membrane body is fixedly installed on the inner wall of the main recovery membrane shell, and guide plates are fixedly installed on both sides of the inner wall of the main recovery membrane shell.

[0010] As a preferred embodiment of this utility model, an air inlet is fixedly installed at the top of the upper membrane cover, an air outlet is fixedly installed at the bottom of the lower membrane cover, and an exhaust fan is fixedly installed inside the lower membrane cover.

[0011] As a preferred embodiment of this utility model, the bottom four corners of the oil and gas negative pressure chamber are fixedly installed with feet by supporting columns, the outer surface of the oil and gas negative pressure chamber is fixedly installed with a pump base near the bottom of the negative pressure pump body, and the top surface of the oil and gas negative pressure chamber is fixedly installed with a cover by screws.

[0012] As a preferred embodiment of this utility model, the hatch cover has a through hole near the center that is adapted to the upper membrane cover, and a sealing ring is fixedly installed around the inner wall of the through hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the negative pressure pump operates, creating a negative pressure environment around the oil and gas recovery membrane assembly inside the negative pressure chamber. The mixed gas inside the membrane assembly is then fully compressed by the pressure, passing through the membrane body and entering the negative pressure chamber via a one-way valve. It is then discharged through the gas system and finally transported to the next processing unit via the outlet on the negative pressure pump. The automatic pressure supply component design not only makes the structure more rational and simple but also facilitates maintenance by being externally located outside the negative pressure chamber. It also enables omnidirectional pressure supply, maximizing the utilization rate of the negative pressure chamber. This effectively solves the technical problem of existing oil and gas recovery processing devices where the pressure supply section of the membrane assembly primarily relies on a drive unit for mechanical pressure supply, resulting in a complex structure, cumbersome maintenance, and low utilization of the side frame due to the inability to supply pressure from only one side.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] This utility model provides an oil and gas recovery combined membrane treatment device for an oil and gas recovery treatment device. The automatic pressure supply component is designed to be more reasonable and simple in structure. It is also externally placed outside the oil and gas negative pressure chamber, which facilitates fault maintenance. It can also achieve all-round pressure supply, thereby maximizing the utilization rate of the oil and gas negative pressure chamber and effectively solving the problems mentioned in the background art.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An oil and gas recovery combined membrane treatment device for an oil and gas recovery treatment apparatus includes an oil and gas negative pressure chamber 1, an oil and gas recovery membrane module 2, and an automatic pressure supply module 3. The oil and gas recovery membrane module 2 is installed through the center of the interior of the oil and gas negative pressure chamber 1, and the automatic pressure supply module 3 is provided on the outer surface of the oil and gas negative pressure chamber 1.

[0025] The oil and gas recovery membrane assembly 2 includes a main recovery membrane shell 21 located inside the oil and gas negative pressure chamber 1. Several sets of one-way valves 211 arranged in a ring are fixedly installed on the outer surface of the main recovery membrane shell 21 from top to bottom. A recovery membrane body 212 is fixedly installed on the inner wall of the main recovery membrane shell 21. Guide plates 213 are fixedly installed on both sides of the inner wall of the main recovery membrane shell 21. An upper membrane shell cover 22 is spirally installed at the top of the main recovery membrane shell 21. An air inlet 221 is fixedly installed at the top of the upper membrane shell cover 22. A lower membrane shell cover 2 is fixedly installed at the bottom of the main recovery membrane shell 21. 3. An air outlet 231 is fixedly installed at the bottom of the lower membrane cover 23. An exhaust fan 232 is fixedly installed inside the lower membrane cover 23. The one-way valve 211 arranged in a ring from top to bottom on the outer surface of the main recovery membrane cover 21 can achieve efficient oil and gas recovery. The upper membrane cover 22, which is spirally installed at the top of the main recovery membrane cover 21, is easy to disassemble and install, so as to facilitate the replacement of the recovery membrane body 212. At the same time, the exhaust fan 232 fixedly installed inside the lower membrane cover 23 can achieve automatic air intake for oil and gas recovery.

[0026] The automatic pressurization assembly 3 is composed of an air supply system 31 and a negative pressure pump body 32. The air supply system 31 includes side-mounted negative pressure pipelines 311 symmetrically distributed on both sides of the oil and gas negative pressure chamber 1. The side-mounted negative pressure pipelines 311 on both sides of the oil and gas negative pressure chamber 1 are connected through a central negative pressure pipeline 312. The side-mounted negative pressure pipelines 311 and the oil and gas negative pressure chamber 1 are connected through a chamber pipe pipeline 313. The air inlet on the negative pressure pump body 32 and the central negative pressure pipeline 312 are connected through a pump pipe pipeline 321. When the negative pressure pump body 32 is working, under its action, the air supply to the inside of the oil and gas negative pressure chamber 1 is close to the oil. The gas recovery membrane module 2 is under negative pressure. At this time, the mixed gas inside the oil and gas recovery membrane module 2 fully passes through the recovery membrane body 212 under the action of air pressure, and enters the interior of the oil and gas negative pressure chamber 1 through the one-way valve 211. It is then discharged by the gas circuit system 31, and finally the recovered oil and gas is transported to the next processing device through the air outlet on the negative pressure pump body 32. The automatic pressure supply component 3 is designed to be more reasonable and simple in structure. It is also externally placed outside the oil and gas negative pressure chamber 1, which facilitates fault maintenance. It can also achieve all-round pressure supply, so as to maximize the utilization rate of the oil and gas negative pressure chamber 1.

[0027] Furthermore, in this embodiment, please refer to Figure 1 At the four corners of the bottom of the oil and gas negative pressure chamber 1, foot 12 is fixedly installed by support columns 11. A pump base 13 is fixedly installed on the outer surface of the oil and gas negative pressure chamber 1 near the bottom of the negative pressure pump body 32. A cover 15 is fixedly installed on the top surface of the oil and gas negative pressure chamber 1 by screws 14. The design of the pump base 13 facilitates the installation and fixing of the negative pressure pump body 32.

[0028] Furthermore, in this embodiment, please refer to Figure 1 The hatch cover 15 has a membrane shell perforation 151 that is compatible with the upper membrane shell cover 22, which is located near the center. A sealing ring is fixedly installed around the inner wall of the membrane shell perforation 151. The membrane shell perforation 151 and the sealing ring around its inner wall can facilitate the disassembly and assembly of the hatch cover 15, and also help to ensure the sealing between the two after installation, thus ensuring the purity of the recovered oil and gas.

[0029] In this embodiment, the specific implementation scenario is as follows: During oil and gas recovery, the exhaust fan 232 operates, and the mixed gas containing oil and gas from the outside is introduced into the interior of the main recovery membrane shell 21 through the air inlet 221. At the same time, the negative pressure pump 32 operates, and under its action, the interior of the oil and gas negative pressure chamber 1 is in a negative pressure state near the oil and gas recovery membrane assembly 2. At this time, the mixed gas inside the oil and gas recovery membrane assembly 2 fully passes through the recovery membrane body 212 under the action of air pressure, and enters the interior of the oil and gas negative pressure chamber 1 through the one-way valve 211. It is then discharged by the air circuit system 31, and finally the recovered oil and gas is transported to the next processing device through the air outlet on the negative pressure pump 32. At the same time, the air that has completed the oil and gas recovery is discharged through the air outlet 231, continuously circulating. Moreover, the design of the automatic pressure supply component 3 is not only more reasonable and simple in structure, but also external to the oil and gas negative pressure chamber 1, which facilitates fault maintenance and can also achieve all-round pressure supply, thereby maximizing the utilization rate of the oil and gas negative pressure chamber 1.
