Description

Technical Field

[0001] This application relates to the technical field of oil and gas recovery and treatment devices, specifically a high-efficiency tertiary oil and gas recovery and treatment device. Background Technology

[0002] Oil and gas recovery devices are equipment that collect and process volatile oil and gas during the loading and unloading of gasoline and refueling of vehicles. Tertiary oil and gas recovery devices typically extract volatile oil and gas from underground oil tanks, then use compressors or condensers to extract the gasoline contained in the oil and gas and reinject it into the oil tanks to reduce gasoline loss and waste. The remaining gas is then processed through a filter to remove pollutants and harmful substances, and finally the clean gas is released into the atmosphere.

[0003] Chinese patent CN202320681496.8 discloses a three-stage oil and gas recovery treatment device, comprising: at least one first condensing component, a second condensing component, and a membrane filter component. The first condensing component includes at least two nested primary and secondary condensers. The inlet of the primary condenser is connected to an underground oil tank, and the oil and gas from the underground oil tank flow sequentially through the primary and secondary condensers. The inlet of the second condensing component is connected to the outlet of the secondary condenser, and the liquid outlets of both the second and first condensing components are connected to the underground oil tank. The membrane filter component is connected to the gas outlet of the second condensing component. The first gas outlet of the membrane filter component is connected to an exhaust pipe, and the second gas outlet of the membrane filter component is connected to the inlet of the second condensing component via a vacuum pump. This device is used to solve the problems of unsatisfactory oil and gas recovery effect, secondary hazardous waste generated by carbon adsorption, and short replacement cycle.

[0004] In the aforementioned prior art, a concentration detector is used to detect the concentration of oil and gas in the discharged gas. However, when the concentration of oil and gas in the gas exceeds the standard, it cannot immediately stop the discharge of the gas, resulting in the discharge of gas with excessive concentration causing an impact on the surrounding environment.

[0005] Therefore, it is necessary to provide a high-efficiency tertiary oil and gas recovery treatment device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a high-efficiency tertiary oil and gas recovery treatment device to achieve the effect of re-treating gases with excessive concentrations.

[0008] The technical solution adopted by this application to solve its technical problem is: a high-efficiency three-stage oil and gas recovery treatment device, including a three-stage oil and gas recovery treatment box and a first exhaust pipe and a concentration detector located on the first exhaust pipe. The end of the first exhaust pipe is connected to a second exhaust pipe, and a gas treatment component for treating gas with excessive oil and gas concentration is provided on one side of the second exhaust pipe.

[0009] The gas treatment assembly includes a solenoid valve installed on a second exhaust pipe and a first connecting pipe connected to the second exhaust pipe. The end of the first connecting pipe is connected to a filter box, and the filter box is equipped with a filter plate. One side of the filter box is connected to a second connecting pipe, and a fan for generating negative pressure inside the filter box is installed on the second connecting pipe. The end of the second connecting pipe is connected to the first exhaust pipe.

[0010] Furthermore, the filter box is provided with a limiting block inside, and the filter plate is provided with a fixing frame on the outside, and the limiting block is adapted to the fixing frame.

[0011] Furthermore, the filter box has a through hole at its lower end, an oil storage tank at its lower end, an oil drain pipe at its lower end, and a valve installed on the outside of the oil drain pipe.

[0012] Furthermore, a baffle is provided on the rear side of the filter box, a sealing block is provided on one side of the baffle, and a snap-fit ​​component is provided on the baffle for connecting the baffle and the filter box.

[0013] Furthermore, a groove and a slot are provided on one side of the filter box for connecting the card connector, and the groove and the slot are connected.

[0014] Furthermore, the snap-fit ​​component includes a fixing block that is fixedly connected to the baffle. The fixing block is adapted to the groove. An internal cavity is provided on one side of the fixing block. A wedge block is slidably connected inside the internal cavity. The wedge block is adapted to the snap-fit ​​groove. A first spring is provided inside the internal cavity.

[0015] Furthermore, the filter box is provided with a through groove, which is connected to the card slot.

[0016] Furthermore, the interior of the through groove is provided with an extrusion member for extruding the wedge-shaped block.

[0017] Furthermore, the extrusion member includes an extrusion rod slidably connected inside the through groove, the top of the extrusion rod is provided with a pressing plate, and the outer side of the extrusion rod is provided with a second spring.

[0018] Furthermore, the filter plate is a component made of activated carbon, and the sealing block is a component made of rubber.

[0019] The beneficial effects of this application are: the high-efficiency three-stage oil and gas recovery treatment device provided by this application detects whether the gas concentration exceeds the standard by using a concentration detector. When the concentration exceeds the standard, the solenoid valve is closed and the fan is started to allow the gas in the second exhaust pipe to enter the filter box for filtration. Then the gas enters the first exhaust pipe again and is detected by the concentration detector. When the gas no longer exceeds the standard, the solenoid valve can be opened to allow the gas to be discharged from the end of the second exhaust pipe, preventing the gas with excessive concentration from affecting the environment.

[0020] Secondly, this application enables the baffle to be quickly installed and removed through the cooperation of grooves, slots, snap-fit ​​parts and extrusion parts, thereby facilitating the disassembly and replacement of the filter plates inside the filter box and further improving work efficiency.

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] like Figures 1 to 6 As shown, this application provides a high-efficiency three-stage oil and gas recovery treatment device, including a three-stage oil and gas recovery treatment box 1, a first exhaust pipe 2, and a concentration detector 21 on the first exhaust pipe 2. The end of the first exhaust pipe 2 is connected to a second exhaust pipe 3, and a gas treatment component 4 for treating gases with excessive concentration is provided on one side of the second exhaust pipe 3.

[0036] The gas treatment component 4 is equipped with a solenoid valve 41 on the second exhaust pipe 3 and a first connecting pipe 42 connected to the second exhaust pipe 3. The solenoid valve 41 is used to control the opening and closing of the end of the second exhaust pipe 3. The end of the first connecting pipe 42 is connected to a filter box 43. The filter box 43 is equipped with a limiting block 432 inside. Multiple sets of limiting blocks 432 are provided. Filter plates 431 are provided between the multiple sets of limiting blocks 432. A fixing frame 4311 is provided on the outside of the filter plate 431. The fixing frame 4311 is adapted to the gap between the two sets of limiting blocks 432. The filter plate 431 is made of activated carbon material. The filter plate 431 is used to filter the gas exceeding the standard again. A second connecting pipe 44 is connected to one side of the filter box 43. A fan 441 is installed on the second connecting pipe 44. The fan 441 is used to generate negative pressure in the filter box 43, so that the gas in the second exhaust pipe 3 can enter the filter box 43. The end of the second connecting pipe 44 is connected to the first exhaust pipe 2.

[0037] In this embodiment, after the oil and gas are processed by the three-stage oil and gas recovery treatment box 1, the gas enters the second exhaust pipe 3 through the first exhaust pipe 2. When the concentration detector 21 located on the first exhaust pipe 2 detects that the concentration of oil and gas in the gas exceeds the standard, the controller (which is prior art and is not shown in the figure, and will not be described in detail) controls the solenoid valve 41 to close, thereby closing the end of the second exhaust pipe 3. At this time, the control fan 441 is started, and the fan 441 creates a negative pressure inside the filter box 43. The gas located inside the second exhaust pipe 3 enters the filter box 43 through the first connecting pipe 42, and then enters the second connecting pipe 44 after being filtered by multiple sets of filter plates 431. Then it returns to the first exhaust pipe 2. Then the control solenoid valve 41 is opened, so that the filtered gas is discharged through the second exhaust pipe 3, thereby preventing the discharge of gas when the concentration of oil and gas in the gas exceeds the standard, and avoiding the impact of the excessive gas discharge on the surrounding environment.

[0038] like Figure 4 and Figure 6 As shown, the filter box 43 has a through hole 433 at its lower end, and an oil storage tank 434 is provided at the bottom of the filter box 43. The lower end of the oil storage tank 434 is connected to an oil drain pipe 435, and a valve 4351 is installed on the oil drain pipe 435.

[0039] In this embodiment, after the filter plate 431 filters the oil and gas, some of the gasoline in the oil and gas adheres to the filter plate 431 and gradually moves down under the action of gravity and enters the oil storage tank 434 through the through hole 433. When it has been used for a long time and reaches a certain amount, the oil located inside the oil storage tank 434 can be discharged through the drain pipe 435 by opening the valve 4351.

[0040] like Figures 5 to 8As shown, a baffle 45 is provided on one side of the filter box 43, and a sealing block 451 is provided on one side of the baffle 45. The sealing block 451 is made of rubber. A snap-fit ​​part 452 for connecting the baffle 45 and the filter box 43 is provided on the baffle 45. A groove 436 and a slot 437 for connecting the snap-fit ​​part 452 are provided on one side of the filter box 43. The groove 436 and the slot 437 are connected. The snap-fit ​​part 452 includes a fixing block 4521. The fixing block 4521 is connected to the baffle 45 and is adapted to the groove 436. An internal cavity 4522 is provided on one side of the fixing block 4521. A wedge block 4523 is slidably connected inside the internal cavity 4522. The wedge block 4523 is adapted to the slot 437. A first spring 4524 is provided inside the internal cavity 4522. The first spring 4524 is connected to the wedge block 4523.

[0041] In this embodiment, when installing the filter plate 431, the fixing frame 4311 on the outside of the filter plate 431 is aligned with the limiting block 432 and inserted. Then, the fixing block 4521 on the baffle 45 is aligned with the groove 436 and inserted. Under the contact inside the groove 436, the wedge block 4523 moves into the inner cavity 4522 and the first spring 4524 is squeezed. When the wedge block 4523 is in the slot 437, the first spring 4524 rebounds and inserts the wedge block 4523 into the slot 437, completing the snap-fit. At this time, the baffle 45 is fixed to one side of the filter box 43 and sealed by the sealing block 451, thereby quickly and conveniently completing the installation of the filter plate 431.

[0042] like Figure 7 As shown, a through groove 4371 is provided on the filter box 43. The through groove 4371 is connected to the slot 437. Inside the through groove 4371, there is an extrusion member 453 for extruding the wedge block 4523. The extrusion member 453 includes an extrusion rod 4531 that is slidably connected inside the through groove 4371. The top of the extrusion rod 4531 is provided with a pressing plate 4532. The outside of the extrusion rod 4531 is provided with a second spring 4533. The two ends of the second spring 4533 are respectively connected to the pressing plate 4532 and the outside of the filter box 43.

[0043] In this embodiment, when the filter plate 431 needs to be disassembled and replaced, the pressing plate 4532 is pressed, which drives the pressing rod 4531 to move into the slot 437. This allows the end of the pressing rod 4531 to press the wedge block 4523 located inside the slot 437, separating the wedge block 4523 from the slot 437. Then, the baffle 45 can be pulled outward to separate it from the filter box 43, allowing the filter plate 431 to be pulled out from between the limiting blocks 432 for easy replacement or cleaning. When the pressing plate 4532 is pressed, it compresses the second spring 4533. After the fixing block 4521 separates from the groove 436, the pressing plate 4532 and the pressing rod 4531 are reset under the elastic force of the second spring 4533, so that the baffle 45 can be reinstalled.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
