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 skid-mounted exhaust gas treatment device. Background Technology

[0002] Gas stations use vapor recovery systems. The process begins with adsorbing the vapors using an adsorbent. After separation and adsorption in a tower, harmful substances are removed, leaving only carbon dioxide, nitrogen, and water vapor. The vapors are then filtered to remove impurities and dust from the air. Finally, the vapors are released into the atmosphere through exhaust pipes.

[0003] Most oil and gas recovery systems use physical methods. In the early stages of installation, these systems show significant results in oil and gas recovery and treatment, and exhaust emissions meet standards. However, over time, the processing devices within the oil and gas recovery system are prone to blockage by oil and gas, leading to increasingly poor treatment performance and eventual failure. The concentration of oil and gas in the exhaust gas emitted into the air becomes higher and higher. Furthermore, due to differences in the processing capacity of the equipment and the size of the filter elements, it is difficult to assemble and position filter elements of different sizes according to usage requirements. Summary of the Invention

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

[0005] A skid-mounted exhaust gas treatment device for oil and gas recovery includes an adsorption chamber, a gas detection module, and air filters. An instrument support plate is positioned directly above the adsorption chamber, with fasteners extending through its outer side. A positioning mechanism is positioned directly below the instrument support plate. This positioning mechanism positions the outer side of air filters of different sizes according to the purification process, thereby improving the efficiency of disassembling and installing air filters of different sizes. A control mechanism is located on the outer side of the adsorption chamber. Based on the quality of exhaust gas treatment by the adsorption chamber, the control mechanism determines whether secondary treatment of the exhaust gas is required, thereby controlling the quality of exhaust gas emissions.

[0006] Preferably, the positioning mechanism includes an isolation pad, an instrument tray, an air filter, a material support plate, side positioning arms, positioning holes, and guide grooves. The isolation pad is located directly below the material support plate, the air filter is connected directly above the material support plate, the instrument tray is located directly above the air filter, the side positioning arms are evenly spaced at the bottom of the instrument tray, the guide grooves are formed on the outer side of the side positioning arms, and the instrument tray is connected to the outer side of the guide grooves.

[0007] Preferably, the side positioning arm is connected to both sides of the material support plate through a guide groove opened on the outer side.

[0008] Preferably, the control mechanism includes a gas detection module, a manual exhaust valve, a second adsorption chamber, an electromagnetic exhaust valve, and an exhaust pipe. The gas detection module is installed on one side of the first adsorption chamber. The tail end of the first adsorption chamber is connected to the manual exhaust valve. The top end of the first adsorption chamber is connected to the input end of the electromagnetic exhaust valve. The output end of the electromagnetic exhaust valve is connected to the bottom end of the second adsorption chamber. The top end of the second adsorption chamber is connected through an exhaust pipe.

[0009] Preferably, the second adsorption chamber is connected to the top of the first adsorption chamber via a manual exhaust valve connected to its bottom.

[0010] Preferably, the side positioning arm is connected to both sides of the air filter element through positioning holes that are equally spaced on the outer side.

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

[0012] 1. During use, the guide grooves on the side are used to position the two sides of the material support plate. During use, the air filter is quickly assembled and positioned according to the positioning process of the air filter, which improves the flexibility of assembling air filters of different lengths or numbers. The isolation pads set at the bottom of the material support plate are used to block the gaps in the adsorption box, and the conveying size is controlled according to the processing requirements.

[0013] 2. The exhaust gas detection device and unit can replace manual periodic sampling and inspection of exhaust gas, reducing labor costs and improving work efficiency. It can also monitor the concentration of oil and gas in the exhaust gas in real time. When the exhaust gas exceeds the standard, the second adsorption box set at the top is used to perform secondary adsorption treatment on the exhaust gas, thereby controlling the quality of exhaust gas treatment.

A positioning mechanism 6 is positioned directly below the instrument support plate 5. The positioning mechanism 6 positions the outer side of air filters 11 of different sizes according to the purification process, thereby improving the efficiency of disassembly and installation of air filters 11 of different sizes. A control mechanism 9 is positioned on the outer side of the adsorption chamber 1. The control mechanism 9 determines whether to perform secondary treatment of the exhaust gas based on the quality of exhaust gas treatment by the adsorption chamber 1, thereby controlling the quality of exhaust gas emissions.

[0022] In this embodiment, the positioning mechanism 6 includes an isolation pad 4, an instrument tray 5, an air filter 11, a material support plate 12, side positioning arms 13, positioning holes 14, and guide grooves 15. The isolation pad 4 is located directly below the material support plate 12. The air filter 11 is connected directly above the material support plate 12. The instrument tray 5 is located directly above the air filter 11. The side positioning arms 13 are evenly spaced at the bottom of the instrument tray 5. The guide grooves 15 are opened on the outer side of the side positioning arms 13. The instrument tray 5 is connected to the outer side of the guide grooves 15. The isolation pad 4 is used to block the gaps in the air, preventing exhaust gas from being transported through the gaps.

[0023] In this embodiment, the side positioning arm 13 is connected to both sides of the material support plate 12 through the guide groove 15 opened on the outside. The guide groove 15 positions both sides of the material support plate 12, which facilitates dynamic adjustment of the height of the material support plate 12.

[0024] In this embodiment, the control mechanism 9 includes a gas detection module 2, a manual exhaust valve 3, an adsorption box 7, an electromagnetic exhaust valve 8, and an exhaust pipe 10. The gas detection module 2 is installed on one side of the adsorption box 1. The tail end of the adsorption box 1 is connected to the manual exhaust valve 3. The top end of the adsorption box 1 is connected to the input end of the electromagnetic exhaust valve 8. The output end of the electromagnetic exhaust valve 8 is connected to the bottom end of the adsorption box 7. The top end of the adsorption box 7 is connected through the exhaust pipe 10.

[0025] In this embodiment, the second adsorption box 7 is connected to the top of the first adsorption box 1 via a manual exhaust valve 3 connected to its bottom end, and the internal filtered gas of the second adsorption box 7 is directly discharged using the manual exhaust valve 3.

[0026] In this embodiment, the side positioning arm 13 is connected to both sides of the air filter 11 through positioning holes 14 that are equally spaced on the outside, and the positioning holes 14 are used to position the outside of the air filter 11.

[0027] In practical applications, this skid-mounted exhaust gas treatment device for oil and gas recovery includes the following tasks:

[0028] Step 1: During use, the operator slides the outer side of the support plate 12 and the outer side of the guide groove 15 opened on the outer side of the side positioning arm 13 according to the width of the air filter 11, adjusts the height of the support plate 12, inserts screws into the positioning hole 14, positions the side positioning arm 13 and the two sides of the support plate 12, and then installs the air filter 11 of the corresponding size on the outside, and connects the top of the isolation pad 4 to the bottom of the support plate 12.

[0029] Step 2: The operator installs the instrument tray 5 and air filter 11 inside the adsorption chamber 1, and symmetrically installs the fasteners 16 on the top of the instrument tray 5 and the adsorption chamber 1 to complete the positioning of the instrument tray 5. After the treated exhaust gas is directly injected into the adsorption chamber 1, the air filter 11 is used to adsorb and filter the gas, and the purified gas is tested by the gas detection module 2.

[0030] Step 3: The operator observes the data from the gas detection module 2. When the gas test meets the emission requirements, the operator can open the manual exhaust valve 3 to directly discharge the purified exhaust gas inside the adsorption box 1.

[0031] Step 4: When the gas detection module 2 detects that the data does not meet the emission requirements, the operator opens the electromagnetic exhaust valve 8 and introduces the gas treated inside the adsorption chamber 1 into the adsorption chamber 2 7 through the electromagnetic exhaust valve 8. The gas is then purified again by the air filter element 11 inside the adsorption chamber 2 7, and then the purified gas is directly discharged through the exhaust pipe 10.
