Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas recovery, in particular to an atmospheric pressure type membrane separation oil and gas recovery device. Background Technique

[0002] With the improvement and implementation of environmental protection regulations, higher requirements are put forward for oil and gas recovery and volatile organic compound recovery technologies. Compared with traditional thermal oxidation methods, condensation methods, absorption methods, and adsorption methods, the membrane separation method has continuous processes, no heat release, mild conditions, and advantages such as low energy consumption, high safety, and strong processing capacity. Atmospheric pressure type membrane separation means that oil and gas directly enter the membrane module and are separated by atmospheric pressure gas, without the need for compression by a compressor. Therefore, this oil and gas separation method is called atmospheric pressure type membrane separation.

[0003] When the existing atmospheric pressure type membrane separation discharges excess gas, it usually needs to use oil-absorbing cotton and a filter component to filter the gas twice to reduce air pollution caused by gas discharge. The existing oil-absorbing cotton and filter structure are usually set as single units. When the filtering effect of the oil-absorbing cotton and filter structure decreases, it is necessary to stop the oil and gas recovery device first, and then disassemble and replace the oil-absorbing cotton and filter structure. Shutting down the oil and gas recovery device will cause the oil and gas to not be continuously separated and recovered, and frequent replacement of the oil-absorbing cotton and filter structure will lead to a decrease in the separation and recovery efficiency of the oil and gas, which is rather inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide an atmospheric pressure type membrane separation oil and gas recovery device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An atmospheric pressure type membrane separation oil and gas recovery device, including an oil and gas recovery device, an adsorption component is fixedly connected inside the oil and gas recovery device. The adsorption component includes an adsorption chamber communicated with the air delivery pipe of the oil and gas recovery device. A grid plate is fixedly installed on the inner surface of the adsorption chamber. An oil-absorbing cotton is movably arranged on the upper surface of the grid plate. Driven rollers are symmetrically and rotatably connected inside the adsorption chamber. A driving roller penetrating the adsorption chamber is rotatably arranged on one side of the driven roller. A filter component is fixedly installed inside the adsorption chamber. The filter component includes an air-gathering hood fixedly installed on the inner side surface of the adsorption chamber. A filter chamber is fixedly installed on the lower surface of the air-gathering hood. A first filter cylinder is fixedly installed on the upper surface of the inner side of the filter chamber. A second filter cylinder is movably arranged inside the first filter cylinder. A third filter cylinder is movably arranged inside the second filter cylinder.

[0007] Furthermore, partition plates are symmetrically and fixedly installed on the inner surface of the adsorption bin. The oil-absorbing cotton movably penetrates through the two partition plates. The oil-absorbing cotton passes between the driven roller and the driving roller. Railings are symmetrically and fixedly installed on the upper surface of the grille plate on both sides of the oil-absorbing cotton.

[0008] Furthermore, a first motor is fixedly installed on one surface of the adsorption bin. The output end of the first motor is fixedly connected to a driving roller. Belt wheel assemblies are fixedly connected to one ends of the two driving rollers.

[0009] Furthermore, a blocking assembly is fixedly arranged on the upper surface inside the adsorption bin. The blocking assembly includes an electric push rod fixedly embedded in the upper surface of the adsorption bin. A connecting frame is fixedly installed at the output end of the electric push rod. Flap plates are symmetrically and fixedly installed on the lower surface of the connecting frame.

[0010] Furthermore, second limit rings are fixedly installed at the lower ends of the inner surfaces of the first filter cartridge and the second filter cartridge. First limit rings are fixedly installed at the upper ends of the outer surfaces of the second filter cartridge and the third filter cartridge.

[0011] Furthermore, an exhaust pipe penetrating through the lower surface of the adsorption bin is fixedly installed at the lower end of the filtration bin. A baffle slides through the outer surface of the exhaust pipe. A rack is fixedly installed on the lower surface of the baffle. A second motor is fixedly installed on the outer surface of the exhaust pipe. A gear is fixedly installed at the output end of the second motor. The gear is movably meshed with the rack.

[0012] Furthermore, an oil drain pipe is fixedly installed on the lower surface of the adsorption bin.

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

[0014] 1. By operating the first motor, the two driving rollers rotate synchronously, pushing the oil-absorbing cotton to move. The oil-absorbing cotton that has adsorbed oil enters between the driving roller and the driven roller, and the oil-absorbing cotton that has not adsorbed oil moves above the grille plate for adsorption. By adjusting the forward and reverse rotation of the first motor, the position of the oil-absorbing cotton is repeatedly adjusted, so that different positions of the oil-absorbing cotton are filtered. When the oil-absorbing cotton is pushed to move, the oil adsorbed by the oil-absorbing cotton is squeezed out, enabling the oil-absorbing cotton to be continuously used and enabling the gas discharged by the oil and gas recovery device to be continuously filtered.

[0015] 2. The second motor operates to move the baffle plate and remove it from below the first filter cartridge. At this time, the filtering effect of the first filter cartridge decreases. When the gas flows, it pushes the first filter cartridge downward to expose the second filter cartridge, enabling the second filter cartridge to be put into use for filtering. Similarly, after the filtering effect of the second filter cartridge decreases, the third filter cartridge is exposed. Thus, by moving the baffle plate, multiple filter cartridges are continuously moved downward and put into use, increasing the service life of the filter cartridges, reducing the frequency of replacing the filter cartridges, and increasing the service life of the filter cartridges to prevent the separation and recovery efficiency of oil and gas from decreasing due to frequent replacement of the oil-absorbing cotton and the filtering structure.

[0016] 3. The electric push rod extends to push the connecting frame downward, pressing the retaining piece against the oil-absorbing cotton to block the oil-absorbing cotton from both sides, preventing gas from discharging from the oil-absorbing cotton through the partition plate and restricting the gas flow direction.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, an atmospheric pressure membrane separation oil and gas recovery device includes an oil and gas recovery device 1. An adsorption assembly 2 is fixedly connected inside the oil and gas recovery device 1. The adsorption assembly 2 includes an adsorption chamber 201 communicated with the air inlet pipe of the oil and gas recovery device 1. A grid plate 203 is fixedly installed on the inner surface of the adsorption chamber 201. An oil absorption cotton 206 is movably arranged on the upper surface of the grid plate 203. Driven rollers 204 are symmetrically and rotatably connected inside the adsorption chamber 201. One side of the driven roller 204 is rotatably provided with a driving roller 205 penetrating through the adsorption chamber 201. A filtering assembly 3 is fixedly installed inside the adsorption chamber 201. The filtering assembly 3 includes a gas collecting hood 301 fixedly installed on the inner side surface of the adsorption chamber 201. A filtering chamber 302 is fixedly installed on the lower surface of the gas collecting hood 301. A first filter cartridge 304 is fixedly installed on the upper surface of the inner side of the filtering chamber 302. A second filter cartridge 305 is movably arranged inside the first filter cartridge 304. A third filter cartridge 306 is movably arranged inside the second filter cartridge 305.

[0025] Specifically, the adsorption cotton 206 can be adsorbed at different positions through the adsorption assembly 2, and then the gas is filtered through the filtering assembly 3. By moving down multiple filter cartridges, multiple filter cartridges are continuously put into use in sequence. Embodiment 1

[0026] As Figure 4 shown, in this embodiment, partition plates 202 are symmetrically and fixedly installed on the inner side surface of the adsorption chamber 201. The oil absorption cotton 206 movably penetrates through the two partition plates 202. The oil absorption cotton 206 passes through between the driven roller 204 and the driving roller 205. Railings 207 are symmetrically and fixedly installed on the upper surface of the grid plate 203 on both sides of the oil absorption cotton 206. A first motor 208 is fixedly installed on one side surface of the adsorption chamber 201. The output end of the first motor 208 is fixedly connected to a driving roller 205. Belt wheel assemblies 209 are fixedly connected to one ends of the two driving rollers 205. An oil drain pipe 6 is fixedly installed on the lower surface of the adsorption chamber 201.

[0027] In this embodiment, the first motor 208 operates. Through the transmission of the pulley assembly 209, the two driving rollers 205 rotate synchronously. With the assistance of the driven roller 204, the oil-absorbing cotton 206 is pushed to move. The oil-absorbing cotton 206 that has adsorbed oil enters between the driving roller 205 and the driven roller 204, and the oil is extruded from the inside of the oil-absorbing cotton 206. The oil-absorbing cotton 206 that has not adsorbed oil moves above the grid plate 203 for adsorption. By adjusting the forward and reverse rotation of the first motor 208, the position of the oil-absorbing cotton 206 is repeatedly adjusted, so that different positions of the oil-absorbing cotton 206 are filtered. When the oil-absorbing cotton 206 is pushed to move, the oil adsorbed by the oil-absorbing cotton 206 is extruded, enabling the continuous use of the oil-absorbing cotton 206 and enabling the gas discharged from the oil and gas recovery device to be continuously filtered.

[0028] As Figure 5 shown, second limit rings 308 are fixedly installed at the lower ends of the inner surfaces of the first filter cartridge 304 and the second filter cartridge 305. First limit rings 307 are fixedly installed at the upper ends of the outer surfaces of the second filter cartridge 305 and the third filter cartridge 306. A exhaust pipe 303 is fixedly installed at the lower end of the filtration chamber 302, passing through the lower surface of the adsorption chamber 201. A baffle 5 slidably penetrates the outer surface of the exhaust pipe 303. A rack 501 is fixedly installed on the lower surface of the baffle 5. A second motor 502 is fixedly installed on the outer surface of the exhaust pipe 303. The output end of the second motor 502 is fixedly installed with a gear 503, and the gear 503 is movably meshed with the rack 501.

[0029] During specific implementation, the second motor 502 operates, driving the gear 503 to rotate. Through the meshing transmission of the gear 503 and the rack 501, the rack 501 drives the baffle 5 to move, so that it moves out from below the first filter cartridge 304. At this time, the filtering effect of the first filter cartridge 304 decreases. When the gas flows, it pushes the first filter cartridge 304 downward, exposing the second filter cartridge 305. The first limit ring 307 is supported by the second limit ring 308 for positioning, enabling the second filter cartridge 305 to be put into use for filtering. Similarly, after the filtering effect of the second filter cartridge 305 decreases, the third filter cartridge 306 is exposed. Thus, through the movement of the baffle 5, multiple filter cartridges are continuously lowered and put into use, increasing the service life of the filter cartridges, reducing the number of filter cartridge replacements, increasing the service life of the filter cartridges, so as to avoid the decrease in the separation and recovery efficiency of oil and gas caused by frequent replacement of the oil-absorbing cotton 206 and the filtering structure. Embodiment Two

[0030] On the basis of Embodiment One, in order to make up for the problem that gas easily flows out through the partition plate 202 of the oil-absorbing cotton 206 in Embodiment One.

[0031] As Figure 2 and Figure 4As shown, in this embodiment, a baffle assembly 4 is fixedly provided on the inner upper surface of the adsorption bin 201. The baffle assembly 4 includes an electric push rod 401 fixedly embedded and installed on the upper surface of the adsorption bin 201. The output end of the electric push rod 401 is fixedly installed with a connecting frame 402, and baffle plates 403 are symmetrically and fixedly installed on the lower surface of the connecting frame 402.

[0032] During specific implementation, the electric push rod 401 extends, pushing the connecting frame 402 downward, causing the baffle plates 403 to press down on the oil-absorbing cotton 206, blocking the oil-absorbing cotton 206 from both sides, preventing gas from discharging from the oil-absorbing cotton 206 through the partition plate 202, and restricting the flow direction of the gas.
