Description

Technical Field

[0001] The present application relates to the technical field of oil and gas detection, and in particular to a detection device for oil and gas recovery at a gas station. Background Art

[0002] During normal operations, gas stations must install and use a gas station vapor recovery system to ensure that any overflowing gas generated during the sales process is recovered in the gas station's buried storage tanks, thereby achieving resource reuse and reducing the adverse impact of gas emissions on the atmospheric environment. However, with the increasing popularity of light vehicles equipped with ORVR systems, the ORVR system can automatically capture and store the gas released from the fuel tank during refueling, reducing the amount of gas directly discharged from the fuel tank into the gas station's vapor recovery system, significantly reducing gas emissions during refueling. When facing light vehicles equipped with ORVR systems, gas stations must install and use gasoline pumps with ORVR functions.

[0003] The existing oil and gas recovery volume detection equipment is mainly based on the operating logic of traditional fuel pumps to monitor the oil and gas flow overflowing from the fuel tank when refueling non-ORVR vehicles, but it cannot be adapted to gasoline fuel pumps with ORVR function. As a result, the existing oil and gas recovery volume monitoring equipment cannot accurately detect the oil and gas flow discharged from the fuel tank through the exhaust pipe when refueling with gasoline fuel pumps with ORVR function.

[0004] Therefore, developing a device for detecting the oil and gas flow discharged from the fuel tank through the exhaust pipe when filling gasoline is suitable for both fuel nozzles without ORVR function and fuel nozzles with ORVR function has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In view of this, the present application proposes a gas station oil and gas recovery detection device, comprising: an oil barrel, an oil and gas discharge pipe, a first fuel pipe, a second fuel pipe and a gas flow meter;

[0006] The oil barrel is provided with a pipeline chamber and an oil storage chamber from top to bottom, and the inner cavity of the oil storage chamber is separated from the inner cavity of the pipeline chamber by an isolation plate;

[0007] The top of the fuel drum is provided with a first fuel inlet and a second fuel inlet, which are respectively adapted to be adapted to fueling guns without ORVR function and fueling guns with ORVR function;

[0008] The first refueling port is connected to the oil storage chamber of the oil barrel through a first refueling pipe; the second refueling port is connected to the oil storage chamber of the oil barrel through a second refueling pipe; and the diameter of the first refueling pipe is larger than the diameter of the second refueling pipe;

[0009] One end of the oil and gas discharge pipe is connected to the oil storage chamber, and the other end of the oil and gas discharge pipe protrudes from the oil barrel; a gas flow meter is arranged at the end of the oil and gas discharge pipe protruding from the oil barrel, and is suitable for detecting the oil and gas flow discharged through the oil and gas discharge pipe.

[0010] In one possible implementation, the first refueling pipe is provided with a first air return pipe; one end of the first air return pipe is connected to the first refueling pipe, and the other end of the first air return pipe is fixedly arranged on the side of the isolation plate away from the oil storage chamber and is connected to the cavity of the oil storage chamber.

[0011] In one possible implementation, the main bodies of the first refueling pipe and the first air return pipe are both stepped tubular structures.

[0012] In one possible implementation, the second refueling pipe is provided with a second air return pipe; one end of the second air return pipe is connected to the second refueling pipe, and the other end of the second air return pipe is fixedly arranged on the side of the isolation plate away from the oil storage chamber and is connected to the cavity of the oil storage chamber.

[0013] In one possible implementation, the main body of the second refueling pipe is a stepped tubular structure, and the main body of the second air return pipe is an L-shaped tubular structure.

[0014] In a possible implementation, it further includes a pressure gauge and a pressure tube; one end of the pressure tube passes through the oil tank and is connected to the cavity of the oil storage chamber; and the other end of the pressure tube is provided with a pressure gauge.

[0015] In one possible implementation, an oil unloading pipe is provided on the outer side wall of the oil storage chamber, the oil unloading pipe is communicated with the cavity of the oil storage chamber, and the oil unloading pipe is provided with a valve.

[0016] In one possible implementation, a grounding device is provided at the bottom of the oil drum.

[0017] Beneficial effects of this application

[0018] By combining the simulation of the original light vehicle fuel filling system (i.e. the refueling line and fuel tank of the National V vehicle) and the simulation of the light vehicle using the ORVR fuel filling system (i.e. the refueling line and fuel tank of the National VI vehicle) into one detection device, it is possible to use the same detection device to simultaneously detect the oil and gas flow discharged through the oil and gas exhaust pipe when the National V and National VI standard vehicles are refueled with gasoline, avoiding the tedious process of replacing the detection equipment, thereby significantly improving the detection efficiency.

[0019] The main bodies of the first fuel filler pipe and the first air return pipe both have a stepped tubular structure, so that the first fuel filler pipe and the first air return pipe are connected to the oil storage chamber in a non-vertical state, thereby ensuring that a liquid seal is formed at the bottom of the first fuel filler pipe during refueling, and preventing oil and gas from being discharged from the first fuel filler pipe, which would cause the fuel gun without the ORVR function to trip due to excessive pressure and stop refueling.

[0029] A detection device for oil and gas recovery at a gas station, such as Figure 1 、 Figure 2 As shown, it includes: an oil barrel 100, an oil and gas discharge pipe 300, a first refueling pipe 212, a second refueling pipe 222, and a gas flow meter 310; the oil barrel 100 is provided with a pipeline chamber 110 and an oil storage chamber 120 from top to bottom, and the internal cavity of the oil storage chamber 120 is separated from the internal cavity of the pipeline chamber 110 by an isolation plate 130; the top of the oil barrel 100 is provided with a first refueling port 211 and a second refueling port 221, which are respectively adapted to adapt to a refueling gun without an ORVR function and a refueling gun with an ORVR function; The first refueling port 211 is connected to the oil storage chamber 120 of the oil barrel 100 through the first refueling pipe 212; the second refueling port 221 is connected to the oil storage chamber 120 of the oil barrel 100 through the second refueling pipe 222; and the diameter of the first refueling pipe 212 is larger than the diameter of the second refueling pipe 222; one end of the oil and gas discharge pipe 300 is connected to the oil storage chamber 120, and the other end of the oil and gas discharge pipe 300 protrudes from the oil barrel 100; the gas flow meter 310 is arranged at the end of the oil and gas discharge pipe 300 protruding from the oil barrel 100, and is suitable for detecting the oil and gas flow discharged through the oil and gas discharge pipe 300.

[0030] It should be noted here that the gas station oil and gas recovery detection device of the present application is suitable for detecting the oil and gas flow discharged through the oil and gas discharge pipe 300 when the gas station's gas gun without ORVR function is filling gasoline, and is also suitable for detecting the oil and gas flow discharged through the oil and gas discharge pipe 300 when the gas station's gas gun with ORVR function is filling gasoline; the gas station's gas gun without ORVR function is suitable for inserting into the first gas filling port 211, and the gas station's gas gun with ORVR function is suitable for inserting into the second gas filling port 221, and the pipeline chamber 110 provides installation space for the first gas filling pipe 212 and the second gas filling pipe 222, so that the first gas filling pipe 212 and the second gas filling pipe 222 are connected to the cavity of the oil storage chamber 120 in a non-vertical state, thereby ensuring that when refueling, the first gas filling pipe 212 or the second gas filling pipe 222 is connected to the cavity of the oil storage chamber 120 in a non-vertical state, thereby ensuring that when refueling, the first gas filling pipe 212 or the second gas filling pipe 222 is connected to the cavity of the oil storage chamber 120 A liquid seal is formed at the bottom of the second refueling pipe 222 to prevent oil and gas from being discharged from the first refueling pipe 212 or the second refueling pipe 222, which may cause the refueling gun without ORVR function or the refueling gun with ORVR function to jump and stop refueling due to excessive pressure. The pipeline chamber 110 is placed above the oil storage chamber 120 to facilitate the recovery of oil and gas. The oil storage chamber 120 is suitable for storing gasoline and oil and gas to ensure that the gasoline or oil and gas remain stable during the storage process and reduce evaporation and leakage. The isolation plate 130 is suitable for separating the pipeline chamber 110 and the oil storage chamber 120 to ensure that the functionality and safety of the two cavities do not interfere with each other, effectively preventing corrosion caused by direct contact between gasoline or oil and the first refueling pipe 212 and the second refueling pipe 222, and also reducing the risk of gasoline or oil and gas leakage due to failure of the first refueling pipe 212 or the second refueling pipe 222. This application integrates the simulation of the original light vehicle fuel filling system (i.e., the refueling line and fuel tank of the National V vehicle) and the simulation of the light vehicle using the ORVR fuel filling system (i.e., the refueling line and fuel tank of the National VI vehicle) into one detection device, so that the same detection device can detect the oil and gas flow discharged through the oil and gas exhaust pipe 300 when the National V standard vehicle is filled with gasoline, and can also detect the oil and gas flow discharged through the oil and gas exhaust pipe 300 when the National VI standard vehicle is filled with gasoline, avoiding the tedious process of replacing the detection equipment, thereby significantly improving the detection efficiency.

[0031] Furthermore, the oil and gas discharge pipe 300 is provided with a cavity with openings at both ends. One end of the oil and gas discharge pipe 300 is fixedly arranged on the isolation plate 130 and is connected to the cavity of the oil storage chamber 120. The other end of the oil and gas discharge pipe 300 extends out of the oil barrel 100 and is connected to the inlet of the gas flow meter 310. The outlet of the gas flow meter 310 is connected to the oil and gas recovery system of the gas station.

[0032] In one possible implementation, the first refueling port 211 is suitable for simulating the fuel refueling port of an original light vehicle, and the second refueling port 221 is suitable for simulating the fuel refueling port of a light vehicle using an ORVR fuel refueling system. The first refueling port 211 and the second refueling port 221 are both fixedly arranged on the top of the oil barrel 100 by welding.

[0033] Furthermore, the first refueling pipe 212 is suitable for simulating the refueling line of an original light vehicle. The two ends of the first refueling pipe 212 are respectively connected to the first refueling port 211 and the oil storage chamber 120 by welding, and the first refueling pipe 212 is located in the cavity of the pipeline chamber 110.

[0034] Furthermore, the second refueling pipe 222 is suitable for simulating the refueling line of a light vehicle using an ORVR fuel filling system. The two ends of the second refueling pipe 222 are respectively connected to the second refueling port 221 and the oil storage chamber 120 by welding, and the second refueling pipe 222 is located in the cavity of the pipeline chamber 110, and the oil and gas discharge pipe is located in the cavity of the pipeline chamber 110.

[0035] Furthermore, one end of the oil and gas discharge pipe 300 is fixedly mounted on the isolation plate 130 by welding and communicates with the cavity of the oil storage chamber 120, and the other end of the oil and gas discharge pipe 300 extends out of the oil barrel 100. Preferably, the inner diameter of the oil and gas discharge pipe 300 is in the range of 20-25 mm.

[0036] Furthermore, isolation plate 130 is placed horizontally within the cavity of oil drum 100, with its perimeter welded to the inner wall of oil drum 100. This welding reduces the joint gap between pipeline chamber 110, isolation plate 130, and oil chamber 120, thereby reducing the risk of oil and gas leakage, improving the sealing of the entire device, and ensuring the accuracy of oil and gas detection. Preferably, the thickness of isolation plate 130 ranges from 1 to 2 mm.

[0037] In one possible implementation, the volume ratio of the pipeline chamber 110 to the oil chamber 120 is 1:2. Preferably, the volume of the pipeline chamber 110 is 40L-50L, and the volume of the oil chamber 120 is 80L-100L.

[0038] In one possible implementation, the first refueling pipe 212 is provided with a first return air pipe 213; one end of the first return air pipe 213 is connected to the first refueling pipe 212, and the other end of the first return air pipe 213 is fixedly arranged on the side of the isolation plate 130 away from the oil storage chamber 120 and is connected to the cavity of the oil storage chamber 120.

[0039] It should be noted here that one end of the first return air pipe 213 is connected to the first refueling pipe 212 by welding, and the other end of the first return air pipe 213 is fixedly connected to the side of the isolation plate 130 away from the oil storage chamber 120 by welding and is connected to the cavity of the oil storage chamber 120. The first return air pipe 213 is suitable for recovering the oil and gas generated in the oil storage chamber 120 into the first refueling pipe 212. When refueling with gasoline, due to the rapid flow rate of gasoline, a negative pressure will be generated in the first refueling pipe 212. The siphon phenomenon caused by the negative pressure will adsorb the oil and gas in the first return air pipe 213 into the first refueling pipe 212, and then the refueling gun without ORVR function will recover the oil and gas into the oil storage tank of the gas station, thereby reducing the direct discharge of oil and gas from the first refueling port 211 into the atmosphere. The welding method design can provide a good sealing effect, so that the connection between the first refueling pipe 212 and the first return air pipe 213 is very stable, ensuring that gasoline will not leak from the connection during transmission.

[0040] Furthermore, the inner diameter of the first refueling pipe 212 is 32 mm, and the overall length of the first refueling pipe 212 is greater than 0.5 m. The inner diameter of the first return air pipe 213 is 12 mm, and the overall length of the first return air pipe 213 is greater than 0.5 m.

[0041] In one possible implementation, the main bodies of first filler pipe 212 and first return air pipe 213 each have a stepped tubular structure. It should be noted that this stepped tubular structure allows first filler pipe 212 and first return air pipe 213 to connect to oil chamber 120 in a non-perpendicular position. This ensures a liquid seal at the bottom of first filler pipe 212 during refueling, preventing oil and gas from escaping from first filler pipe 212 and causing a non-ORVR fuel gun to trip due to excessive pressure.

[0042] The connection method of the first fuel port 211, the first fuel pipe 212, and the oil storage chamber 120 of the present application simulates the original light vehicle fuel filling system (i.e., the fuel pipe and fuel tank of the National V vehicle). The gasoline from the corresponding first fuel port 211 is selected according to the fuel gun that does not have the ORVR function. The gasoline flows into the cavity of the oil storage chamber 120 through the first fuel pipe 212. The gas flow meter 310 detects the oil and gas flow discharged through the oil and gas exhaust pipe. The flow value is obtained by reading the detection data of the gas flow meter 310. This flow value not only reflects the degree of oil and gas emission during refueling, but also can detect the quality of the fuel gun that does not have the ORVR function by calculating the flow value.

[0043] Specifically, a fueling gun without an ORVR function is inserted into the first fueling port 211, and gasoline is filled into the oil barrel 100 with the fueling gun without an ORVR function. The fueling amount on the electronic display screen of the fueling pump and the oil and gas flow value detected by the gas flow meter 310 are read respectively. The gas-liquid ratio value of the fueling gun without an ORVR function is calculated by dividing the oil and gas flow value detected by the gas flow meter 310 by the fueling amount on the electronic display screen of the fueling pump. The calculated gas-liquid ratio value is compared with the gas-liquid ratio range specified in the standard. If the calculated gas-liquid ratio value is within the limit range specified in the standard, the fueling gun without an ORVR function meets the national usage standards. If the calculated gas-liquid ratio value is not within the limit range specified in the standard, it indicates that the fueling gun without an ORVR function may have a leakage or malfunction problem.

[0044] In one possible implementation, the second refueling pipe 222 is provided with a second return air pipe 223; one end of the second return air pipe 223 is connected to the second refueling pipe 222, and the other end of the second return air pipe 223 is fixedly arranged on the side of the isolation plate 130 away from the oil storage chamber 120 and is connected to the cavity of the oil storage chamber 120.

[0045] It should be noted here that one end of the second return air pipe 223 is connected to the second refueling pipe 222 by welding, and the other end of the second return air pipe 223 is fixedly connected to the side of the isolation plate 130 away from the oil storage chamber 120 by welding and is connected to the cavity of the oil storage chamber 120. The second return air pipe 223 is suitable for recycling the oil and gas generated in the oil storage chamber 120 to the second refueling pipe 222. When refueling with gasoline, due to the fast flow rate of gasoline, negative pressure will be generated in the second refueling pipe 222. The siphon phenomenon caused by the negative pressure will siphon the oil in the second return air pipe 223. The oil and gas are absorbed into the second refueling pipe 222, and then the refueling gun with ORVR function recovers the oil and gas into the oil storage tank of the gas station. Since the diameter of the second refueling pipe 222 is smaller than that of the first refueling pipe 212, the suction force of the second refueling pipe 222 is enhanced, thereby preventing the oil and gas from being directly discharged into the atmosphere from the second refueling port 221. The welding method design can provide a good sealing effect, so that the connection between the second refueling pipe 222 and the second return air pipe 223 is very stable, ensuring that gasoline will not leak from the connection during the transmission process.

[0046] Furthermore, the inner diameter of the second refueling pipe 222 is 24 mm, and the overall length of the second refueling pipe 222 is greater than 0.5 m. The inner diameter of the second return air pipe 223 is 5 mm, and the overall length of the second return air pipe 223 is greater than 0.5 m.

[0047] In one possible implementation, the main body of the second fuel filler pipe 222 is a stepped tubular structure, while the main body of the second air return pipe 223 is an L-shaped tubular structure. It should be noted that the second fuel filler pipe 222 and the second air return pipe 223 are connected to the oil storage chamber 120 in a non-perpendicular position. This ensures a liquid seal at the bottom of the second fuel filler pipe 222 during refueling, preventing fuel vapor from escaping from the second fuel filler pipe 222 and causing the ORVR fuel gun to trip due to excessive pressure.

[0048] The connection method of the second fuel inlet 221, the second fuel pipe 222, and the oil storage chamber 120 of the present application simulates the fuel pipe and fuel tank of a light-duty vehicle using an ORVR fuel filling system (i.e., a National VI vehicle). The corresponding second fuel inlet 221 is selected based on the fuel gun with ORVR function being tested. Gasoline flows into the cavity of the fuel storage chamber 120 through the second fuel pipe 222. The gas flow meter 310 detects the flow rate of oil and gas discharged through the oil and gas discharge pipe 300. The flow value is obtained by reading the detection data of the gas flow meter 310. The obtained flow value not only reflects the degree of oil and gas emission of the fuel gun with ORVR function during gasoline filling, but also can be used to test the quality of the fuel gun with ORVR function based on the calculation of the obtained flow value.

[0049] Specifically, the refueling gun with the ORVR function is inserted into the second refueling port 221, and the refueling gun with the ORVR function fills gasoline into the oil barrel 100, and reads the refueling amount on the electronic display screen of the refueling machine and the oil and gas flow value detected by the gas flow meter 310 respectively. The gas-liquid ratio value of the refueling gun with the ORVR function is calculated by dividing the oil and gas flow value detected by the gas flow meter 310 by the refueling amount on the electronic display screen of the refueling machine, and the calculated gas-liquid ratio value is compared with the gas-liquid ratio range specified in the standard. If the calculated gas-liquid ratio value is within the limit range specified in the standard, the refueling gun with the ORVR function meets the national usage standards. If the calculated gas-liquid ratio value is not within the limit range specified in the standard, it indicates that the refueling gun with the ORVR function may have leakage or malfunction problems.

[0050] In one possible implementation, a pressure gauge 420 and a pressure pipe 410 are further included; one end of the pressure pipe 410 passes through the oil tank and communicates with the cavity of the oil storage chamber 120 ; and the other end of the pressure pipe 410 is provided with a pressure gauge 420 .

[0051] It should be noted here that the pressure tube 410 is located in the cavity of the pipeline chamber 110. The pressure tube 410 is provided with a cavity with openings at both ends. One end of the pressure tube 410 is fixed on the isolation plate 130 by welding and is connected to the cavity of the oil storage chamber 120. The other end of the pressure tube 410 is connected to the pressure gauge 420 after protruding from the oil barrel 100. The pressure gauge 420 is suitable for detecting the pressure value of the oil and gas in the oil storage chamber 120. By setting the pressure gauge 420, a refueling gun without an ORVR function or a refueling gun with an ORVR function can judge whether there is a leak in the gas station oil and gas recovery detection device of this application by the change in the pressure value detected by the pressure gauge 420 during the process of refueling gasoline.

[0052] Furthermore, the pressure gauge 420 adopts a diaphragm pressure gauge of the prior art model YE100.

[0053] In one possible implementation, an oil unloading pipe 510 is provided on the outer wall of the oil holding chamber 120 . The oil unloading pipe 510 is communicated with the cavity of the oil holding chamber 120 . The oil unloading pipe 510 is provided with a valve 520 .

[0054] It should be noted here that the oil unloading pipe 510 is fixedly connected to the outer wall of the oil holding chamber 120 by welding and is communicated with the cavity of the oil holding chamber 120. A valve 520 is provided at one end of the oil unloading pipe 510 away from the oil holding chamber 120. The valve 520 is suitable for controlling the opening or closing of the oil unloading pipe 510. By setting the valve 520 on the oil unloading pipe 510, the flow rate of gasoline can be accurately adjusted and controlled to ensure the smooth progress of the oil unloading process.

[0055] In one possible implementation, a grounding device 600 is provided at the bottom of the oil drum 100. It should be noted that one end of the grounding device 600 is welded to the bottom of the oil drum 100, and the other end of the grounding device 600 is connected to an anti-static device. This grounding device 600 can significantly improve the safety of the oil drum 100 and the oil stored therein, reduce the risk of accidents caused by lightning and static electricity, and ensure the safety of personnel and property.

[0056] Furthermore, grounding device 600 includes a clamp and an anti-static wire. One end of the anti-static wire is welded to the bottom of oil drum 100, and the other end of the anti-static wire is fixedly connected to the clamp. The end of the clamp away from the anti-static wire is clamped to the anti-static device, thereby avoiding the risk of accidents caused by static electricity generated during use of the gas station oil vapor recovery detection device of the present application. Preferably, the clamp and anti-static wire are both made of copper.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
