[0024] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0025] Example

[0026] like Figures 1 to 8As shown, the utility model provides an industrial oil and gas recovery and venting device with a multi-stage filtering structure, including a tank body 1, both ends of the tank body 1 are fixedly connected to a cover 2, one side of the cover 2 is fixedly connected to an air inlet pipe 3, the top of the tank body 1 is fixedly connected to an exhaust pipe 4, the top of the exhaust pipe 4 is fixedly connected to an air pump, a multi-stage filtering component 5 is fixedly installed in the tank body 1, and a collecting component 6 is fixedly installed at the bottom of the tank body 1.

[0027] As a further illustration of this embodiment, the existing recovery and venting devices mostly use adsorption method, condensation method and membrane separation method to recover oil and gas. Among them, the pure condensation method needs to reach a very low temperature and consumes a lot of energy. The membrane separation method has a better separation effect, but the cost of the membrane is also high. Therefore, after comprehensive consideration, the adsorption method is a commonly used means in the existing technology. However, the existing adsorption method needs to be cleaned in time due to the adhesion and accumulation of oil and gas during long-term use, otherwise it will have a great impact on the effect of oil and gas separation. The tank body 1 in this embodiment is fixedly connected on both sides by a cover 2. When the internal multi-stage filter assembly 5 needs to be maintained, it is only necessary to remove the cover 2 at one end of the tank body 1 to remove the multi-stage filter assembly 5. The oil is then removed from the tank body 1. Specifically, an air pump is used to extract the gas from the tank, allowing the oil and gas to enter through the intake pipe 3. After passing through the multi-stage filter assembly 5 and reaching the emission standard, it is discharged through the exhaust pipe 4. After a period of operation, the oil and gas attached to the multi-stage filter assembly 5 accumulates to form oil liquid, which is then gathered by gravity in the collection assembly 6 at the bottom of the tank. After the multi-stage filter assembly 5 reaches the upper adsorption limit, the cover 2 is opened to quickly remove the multi-stage filter assembly 5. After cleaning or replacing it, the cleaned or spare multi-stage filter assembly 5 is quickly calibrated and inserted into the tank body 1. The multi-stage filter assembly 5 is adjusted and locked by rotating to complete the entire filtration and cleaning process. The quick-release design of the utility model makes the disassembly and installation of the filter structure very simple and quick. This design can significantly reduce the time and labor costs required to replace or clean the filter screen, thereby improving overall operational efficiency. In addition, the quick disassembly also simplifies the maintenance of the multi-stage filter assembly 5. Workers can more easily access the filter structure for cleaning, inspection, or replacement of filter components without the need for complex tools or specialized skills. The quick-release design allows for replacement or cleaning of the filter structure without requiring production downtime, thereby reducing production line downtime and improving equipment utilization and production efficiency. Frequent and efficient cleaning and maintenance maintain the filter structure in good condition, ensuring that the oil vapor recovery vent maintains high filtration efficiency, thereby improving oil vapor recovery rates and overall production efficiency.

[0028] Based on a preferred solution provided by an industrial oil and gas recovery and venting device with a multi-stage filtering structure, the multi-stage filtering assembly 5 includes a plurality of annular brackets 51 fixedly installed at equal intervals in the tank body 1, a filter plate 52 is fixedly installed in each annular bracket 51, and a plurality of limiting sliders 54 are fixedly installed on the outer periphery of each filter plate 52, the limiting sliders 54 slide along the circumferential direction of the annular bracket, and the plurality of filter plates 52 are penetrated by the same cross bar 53.

[0029] As a further explanation of this embodiment, the use of an annular bracket 51 to clamp the filter plate 52 is to facilitate the replacement of the filter plate 52. When cleaning or replacing the filter plate 52, there is no need to disassemble the frame body. The filter plate 52 in the annular bracket 51 can be directly taken out and replaced, which reduces the labor burden and improves the cleaning efficiency.

[0030] Based on the preferred solution provided by an industrial oil and gas recovery and venting device with a multi-stage filtering structure, multiple annular brackets 51 are provided with avoidance grooves 511 for the sliding of the limit slider 54, the cover 2 and the tank body 1 are fixedly connected by a flange 11, and the outer periphery of each filter plate 52 is provided with multiple mounting holes 521 for installing cross bars 53, and the number of cross bars 53 is multiple.

[0031] As a further explanation of this embodiment, the flange 11 is a common means of connection between pipelines. In addition to maintaining the sealing of the space inside the tank, it can also play a role in quick disassembly and separation, so that the cover 2 can be quickly disassembled and the filter plate 52 can be taken out of the tank body 1 for cleaning. In addition, the purpose of using multiple cross bars 53 to connect multiple filter plates 52 in series is also to be able to simultaneously pull the filter plates 52 out of the annular bracket 51 at one time. At the same time, it can also accurately control the spacing between the multiple filter plates 52 to ensure that the oil and gas have sufficient time to contact the surface of the filter plate 52 when passing through each filter plate 52, so that the oil and gas are more comprehensively adsorbed on the filter plate 52.

[0032] Each avoidance groove 511 is provided with a plurality of card slots 512 for accommodating the limit slider 54. An arch plate 513 for limiting the sliding distance of the limit slider 54 is fixedly installed in the avoidance groove 511, and the arch plate 513 cooperates with the card slot 512 so that the limit slider 54 slides a preset distance in the avoidance groove 511 and then enters the card slot 512 to be locked. A sewage outlet 514 is provided at the bottom of each annular bracket 51.

[0033] As a further explanation of this embodiment, the limit slider 54 slides a preset distance in the avoidance groove 511 and enters the area where the locking groove 512 is located. At this time, the limit slider 54 on the filter plate 52 is driven to fit into the locking groove 512 by pushing and pulling the cross bar 53. When one end of the limit slider 54 enters the locking groove 512, due to the resistance of the arch plate 513 and the locking groove 512, the limit slider 54 cannot slide along the circumferential direction of the filter plate 52, thereby locking the filter plate 52 in the annular bracket 51. By pushing and pulling the cross bar 53 in the opposite direction, the limit slider 54 is driven to disengage from the locking groove 512 and return to the avoidance groove 511, and can slide along the circumferential direction of the filter plate 52 again. In addition, when the oil and dirt gathered in the various slots of the annular bracket 51 form a liquid, it slides to the bottom end of the annular bracket 51 under gravity and can fall out of the collection assembly 6 through the drain outlet 514.

[0034] The annular bracket 51 is provided with a plurality of gaps 515 along the circumferential direction for the limiting slider 54 to pass through. A plurality of annular brackets 51 are installed at equal intervals in the tank body 1. The annular bracket 51 at the front end of the queue is provided with a plurality of baffles 516 corresponding to the gaps 515 one by one.

[0035] As a further explanation of this embodiment, when the filter plate 52 needs to be removed or installed, after aligning the multiple limit sliders 54 with the multiple notches 515 one by one, the cross bar 53 connected in series with the multiple filter plates 52 is pushed into the tank body 1 along the axial direction of the annular bracket 51, and the filter plate 52 is directly rotated after the front end of the cross bar 53 hits the baffle 516, so that the limit slider 54 on the filter plate 52 slides a preset distance in the avoidance groove 511 and hits the arch plate 513, and then the cross bar 53 is pulled in the direction opposite to the entry direction so that the limit slider 54 enters the card slot 512, locking the filter plate 52. Conversely, multiple filter plates 52 can be taken out at the same time.

[0036] The ends of the multiple cross bars 53 away from the air inlet pipe 3 are commonly connected to a common connecting plate 55 , and an extension rod 56 is fixedly mounted on the side wall of the connecting plate 55 .

[0037] As a further illustration of this embodiment, the connecting plate 55 can simultaneously control the movement of multiple crossbars 53. When the multi-stage filter assembly 5 needs to be disassembled or assembled, the position of all filter plates 52 within the annular bracket 51 can be controlled by directly pushing and pulling the extension rod 56, either manually or mechanically. As a further preferred embodiment of this embodiment, a control assembly for controlling the extension rod 56 can be added to the cover 2. When the filter plates 52 are locked, the extension rod 56 is simultaneously locked, further enhancing the stability of the multi-stage filter assembly 5. As a further illustration of this embodiment, activated carbon is the most commonly used adsorbent material in this embodiment. Other adsorbents, such as silica gel or activated fiber, can also adsorb oil and gas, achieving separation between oil, gas, and air. As a further preferred embodiment of this embodiment, the holes in the filter plates 52 are staggered. Specifically, this can create a more complex flow path between the filter plates 52, thereby increasing the residence time of the oil and gas within the tank body 1. This helps to more fully utilize the filter medium and improve filtration efficiency. When the holes are aligned, oil and gas may more easily pass through the direct channels between the filter plates 52, i.e., the channels formed by the aligned holes, causing some oil and gas to escape without being fully filtered. However, misaligned holes can reduce this short-circuiting phenomenon, making the oil and gas more evenly distributed on the filter medium and improving the filtration effect.

[0038] Based on the preferred solution provided by an industrial oil and gas recovery and venting device with a multi-stage filtration structure, the collection component 6 includes an extension frame 61 fixedly installed on the bottom of the tank body 1, and a collection box 62 is fixedly installed on the bottom of the extension frame 61. A collection tank 12 for cooperating with the collection box 62 is provided at the bottom of the tank body 1.

[0039] Based on a preferred solution provided by an industrial oil and gas recovery and venting device with a multi-stage filtering structure, the tank body 1 is externally connected to a constant temperature device for controlling the temperature inside the tank body 1.

[0040] As a further illustration of this embodiment, the viscosity of oil and gas changes with temperature. At low temperatures, the viscosity of oil and gas increases, increasing filtration resistance, affecting filtration speed, and even preventing viscous oil and gas from passing through filter plate 52. Constant temperature control, however, maintains the oil and gas within a suitable temperature range, reducing their viscosity and thereby improving filtration efficiency. Furthermore, under constant temperature conditions, the oil and gas have better fluidity, allowing them to pass more smoothly through the filter medium, reducing clogging and accumulation, and further enhancing filtration effectiveness.
