Description

Technical Field

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

[0002] Oil and gas recovery treatment devices are designed to recover and treat the oil and gas emitted from refueling oil and gas recovery systems using methods such as adsorption, absorption, condensation, and membrane separation. Among these methods, membrane separation technology requires the use of oil and gas recovery membrane modules. Oil vapor in the mixed gas permeates through the membrane for enrichment and recovery, while air is trapped, thereby achieving the purpose of separating oil and gas from air.

[0003] The polymer membrane is installed inside the equipment. After long-term use, the membrane pores are prone to blockage and aging. At this time, the polymer membrane needs to be replaced. However, the internal structure of the equipment is relatively complex and difficult to disassemble, making it inconvenient to replace the polymer membrane. Summary of the Invention

[0004] The purpose of this invention is to provide an oil and gas recovery membrane module for an oil and gas recovery treatment device, so as to solve the above-mentioned defects caused by the prior art.

[0005] The oil and gas recovery membrane module of the oil and gas recovery treatment device includes a separation tank, a columnar membrane, and a vacuum pump. A tank cover is connected to the top of the separation tank, and a drain pipe is connected through the top of the separation tank. A separation mechanism is installed inside the separation tank. The separation mechanism positions the outer side of the columnar membrane, and after the separation tank is opened, a portion of the columnar membrane is pushed out directly for easy handling and disassembly by the operator. A purification mechanism is installed directly below the columnar membrane to further filter the separated liquid, thereby reducing the impurity content in the separated liquid. A vacuum pump is connected through one side of the separation tank.

[0006] Preferably, the separation mechanism includes a columnar membrane, an outer ring, a slider, a spring column, and a guide groove. The outer ring is connected to the outer side of the columnar membrane, and sliders are distributed in a ring around the outer side of the outer ring. One end of the slider is connected to one side of the spring column, and the tail end of the spring column is connected to the slider. The guide groove is distributed in a ring inside the separation tank.

[0007] Preferably, the columnar membrane is connected to the outer side of multiple sets of sliders via an outer sleeve ring.

[0008] Preferably, the separation tank is connected to the outside of the slider through an internally annularly distributed guide grooves.

[0009] Preferably, the purification mechanism includes an air inlet pipe, a collection tray, fasteners, a fine filter element, and discharge holes. A columnar membrane is connected to the outside of the air inlet pipe, and discharge holes are equally spaced on the outside of the air inlet pipe. The collection tray is connected to the outside of the columnar membrane, and a fine filter element is connected through the bottom of the collection tray. Fasteners are arranged in a ring around the outside of the collection tray.

[0010] Preferably, the collection disc is connected to the bottom of the columnar membrane by fasteners provided on the outside.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. When it is necessary to disassemble the columnar membrane, the spring column is released from the pressure of the tank cover and moves the columnar membrane vertically upward, which is convenient for the operator to disassemble. The operator does not need to go deep into the separation tank to disassemble and replace the membrane, saving time for disassembling and replacing the columnar membrane.

[0013] 2. The fine filter element installed at the bottom of the collection plate recovers the initially separated liquid and further separates the gas after oil-gas separation to remove fine particles and impurities such as dust, metal shavings, oil mist, water droplets and other corrosive substances from the fluid, ensuring the purity of the fluid, thereby improving the oil recovery rate, reducing the content of oil mist in the exhaust gas and reducing air pollution.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, the oil and gas recovery membrane module of the oil and gas recovery treatment device includes a separation tank 1, a columnar membrane 4, and a vacuum pump 13. A tank cover 6 is connected to the top of the separation tank 1, and a drain pipe 2 is connected through the top of the separation tank 1. A separation mechanism 8 is provided inside the separation tank 1. The separation mechanism 8 positions the outer side of the columnar membrane 4, so that after the separation tank 1 is opened, a portion of the columnar membrane 4 can be pushed out directly, making it easy for operators to pick up and disassemble. A purification mechanism 9 is provided directly below the columnar membrane 4. The purification mechanism 9 further filters the separated liquid, thereby reducing the impurity content in the separated liquid. A vacuum pump 13 is connected through one side of the separation tank 1.

[0023] In this embodiment, the separation mechanism 8 includes a columnar membrane 4, an outer ring 5, a slider 7, a spring column 14, and a guide groove 15. The outer ring 5 is connected to the outer side of the columnar membrane 4, and the slider 7 is distributed in a ring on the outer side of the outer ring 5. One end of the slider 7 is connected to one side of the spring column 14, and the tail end of the spring column 14 is connected to the slider 7. The guide groove 15 is distributed in a ring inside the separation tank 1.

[0024] In this embodiment, the columnar membrane 4 is connected to the outside of multiple sets of sliders 7 through an outer sleeve ring 5. The sliders 7 are used to position the columnar membrane 4, which facilitates the assembly and positioning of the columnar membrane 4.

[0025] In this embodiment, the separation tank 1 is connected to the outside of the slider 7 through the internal annularly distributed guide grooves 15, and the outer ring 5 is positioned and guided by the guide grooves 15 inside the separation tank 1.

[0026] In this embodiment, the purification mechanism 9 includes an air inlet pipe 3, a collection tray 10, fasteners 11, a fine filter element 12, and discharge holes 16. A columnar membrane 4 is connected to the outside of the air inlet pipe 3. Discharge holes 16 are evenly spaced on the outside of the air inlet pipe 3. The collection tray 10 is connected to the outside of the columnar membrane 4. The fine filter element 12 is connected through the bottom of the collection tray 10. Fasteners 11 are arranged in a ring on the outside of the collection tray 10. The fine filter element 12 filters the separated gas and liquid to reduce the impurity content of the separated substances.

[0027] In this embodiment, the collection tray 10 is connected to the bottom end of the columnar membrane 4 by fasteners 11 on the outside, and the outside of the collection tray 10 is positioned and disassembled by fasteners 11.

[0028] In practical applications, the oil and gas recovery membrane module of this oil and gas recovery treatment device includes the following operations:

[0029] Step 1: During use, depending on the quantity to be processed and the size and length of the columnar membrane 4, the operator installs the outer ring 5 on the outside of the columnar membrane 4, so that the slider 7 set on the outside of the outer ring 5 is connected to the top of the spring column 14, and installs another set of sliders 7 inside the guide groove 15. The sliders 7 and the guide groove 15 are locked with screws to prevent the sliders 7 set at the top from loosening. The top of the columnar membrane 4 is pressed down by the tank cover plate 6, so that the tank cover plate 6 is connected to the top of the separation tank 1.

[0030] Step 2: Simultaneously align the bottom end of the columnar membrane 4 with the outer side of the collection tray 10, and position the columnar membrane 4 and the outer side of the collection tray 10 using fasteners 11. Then, install the fine filter element 12 directly below the collection tray 10. After the liquid separates from the gas, the fine filter element 12 is used to perform secondary filtration on the oil, and the liquid is discharged through the drain pipe 2 at the bottom.

[0031] Step 3: Gas is injected into the interior of the columnar membrane 4 through multiple sets of discharge holes 16 provided on the outside of the intake pipe 3. When the oil-gas mixture comes into contact with the columnar membrane 4, due to the special properties of the columnar membrane 4, different components will have different permeation rates. For example, hydrocarbon molecules in the oil-gas permeate the membrane more easily, while other components such as air are more difficult to permeate. In this way, oil-gas and air are separated.

[0032] Step 4: When the adsorption tank in the oil and gas recovery device is saturated, the vacuum pump 13 is started to evacuate the adsorption tank to a near-vacuum state. The higher the vacuum level of the vacuum pump 13, the better the resolution. When it is necessary to disassemble the columnar membrane 4, the tank cover plate 6 is loosened, so that the spring column 14 loses the pressure of the tank cover plate 6 and drives the columnar membrane 4 to move vertically upward, making it easier for the operator to disassemble.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
