Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile refueling pipes, in particular to an oil and gas recoverable automobile refueling pipe assembly. Background Art
[0002] During the storage, transportation and refueling process, gasoline will naturally evaporate and produce a large amount of oil and gas due to factors such as temperature changes and pressure fluctuations. If not controlled, a gas station may lose about 3% of gasoline due to evaporation each year, which not only causes energy waste but also increases operating costs. The oil and gas recovery system collects the oil and gas generated during the refueling process back to the oil storage tank or reuses it through a specially designed refueling pipe assembly, effectively reducing the unnecessary loss of gasoline, helping to reduce the operating costs of gas stations and improve economic benefits. It also meets the development requirements of a resource-saving society. Gasoline vapor is flammable and explosive, and its escape into the air increases the safety risks in the gas station area. With the advancement of technology, modern refueling pipe assemblies not only need to have good oil and gas sealing performance and physical properties such as oil resistance, aging resistance, and wear resistance, but also need to be able to seamlessly integrate with other system components such as refueling guns, oil and gas recovery pumps, and online monitoring equipment to achieve intelligent control and remote monitoring to meet increasingly stringent environmental regulations and continuously improving operational efficiency standards. In summary, oil and gas recovery is an innovative solution that came into being against the backdrop of resource protection, environmental protection regulations and technological progress. It has become an indispensable environmental protection equipment for modern gas stations by reducing gasoline evaporation losses, reducing environmental pollution, and improving gas station safety and operational efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0012] like Figure 1As shown, an oil and gas recoverable automobile refueling pipe assembly, the oil and gas recoverable automobile refueling pipe assembly specifically includes an oil and gas recovery chamber 1, an oil and gas recovery hose 2, an adsorption separation device, and a vacuum pump 3. The top end of the oil and gas recovery hose 2 is connected to the oil transportation equipment through an air pipe connecting part 4. The oil and gas recovery hose 2 is provided with an oil and gas recovery chamber 1 inside, and a recovery air pipe sealing groove 5 is provided at the bottom of the oil and gas recovery chamber 1. The recovery air pipe sealing groove 5 is connected to the adsorption separation device, and the rear end of the adsorption separation device is connected to an oil and gas temporary storage box 6. The adsorption separation device includes an adsorption material unit 7, a filter 8, and a desorber. 9 and control valve 10, the control valve 10 is connected to the end of the oil and gas recovery hose 2, the filter 8 is arranged below the control valve 10, the adsorption material unit 7 is arranged on the filter 8, the desorber 9 is connected and communicated with the vacuum pump 3 to desorb the oil and gas on the desorber 9 and transport it to the oil and gas temporary storage box 6 through the negative pressure provided, the oil and gas recovery hose 2 is provided with an anti-backflow valve 11 inside, the anti-backflow valve 11 is located on the inner wall of the oil and gas recovery chamber 1, and a quick oil outlet pipe 12 is arranged on one side of the oil and gas temporary storage box 6. During the implementation, the oil and gas recovery chamber is located inside the oil and gas recovery hose 2, which is the key part of oil and gas recovery. It is responsible for collecting the oil and gas mixture generated during the refueling process, and through reasonable structural design, these oil and gas mixtures can be effectively guided and recovered; the oil and gas recovery hose 2 is the core part of the entire recovery system, which not only connects the oil transportation equipment, but also carries important components such as the oil and gas recovery chamber and the recovery gas pipe sealing groove. The flexibility and durability of the hose ensure the stability and safety of the recovery process. The adsorption separation device is a key part of the recovery system, including an adsorption material unit 7, a filter 8, a desorber 9 and a control valve 10. The adsorption material unit 7 uses high-performance activated carbon or other materials with selective adsorption capacity, which can effectively adsorb volatile gasoline vapor in the oil-gas mixture. The filter 8 further filters out impurities to ensure the quality of the recovered oil and gas. The desorber 9 desorbs the adsorbed oil and gas under the action of the vacuum pump 3 and transports it to the oil and gas temporary storage box 6. The control valve 10 is used to adjust and control the recovery process. The vacuum pump 3 provides negative pressure for the desorber, so that the oil and gas adsorbed on the adsorption material can be effectively desorbed and transported to the oil and gas temporary storage box. The use of the vacuum pump 3 not only improves the recovery efficiency, but also ensures the stability and continuity of the recovery process; the recovery gas pipe sealing groove 5 is connected to the adsorption separation device, ensuring the sealing between the oil and gas recovery chamber 1 and the adsorption separation device to prevent oil and gas leakage. The oil and gas temporary storage box 6 is used to store the recovered oil and gas for subsequent reuse. Considering the safe storage and convenient use of oil and gas, the recovered oil and gas can be effectively managed. The anti-backflow valve 11 is located on the inner wall of the oil and gas recovery chamber 1. Its function is to prevent the oil and gas from backflowing during the recovery process, ensuring the unidirectionality and high efficiency of the recovery process. The quick oil outlet pipe 12 is connected to the oil and gas temporary storage box 6, which is convenient for the recovered oil and gas to be discharged for reuse.
[0013] like Figure 1As shown, on the basis of the above method, the adsorption material unit 7 and the filter 8 are further detachably connected to the oil and gas recovery hose. In practice, since they are detachable, when they fail due to long-term use or need to be replaced, the operator can easily remove them from the oil and gas recovery hose and replace them with new parts. This greatly simplifies the maintenance process and reduces maintenance costs. It also reduces the downtime required for replacing parts and improves the overall operating efficiency of the equipment. As the use time increases, the performance of the adsorption material and the filter will gradually decline, affecting the effect of oil and gas recovery. The detachable design allows operators to regularly check and replace these parts to ensure that they are always in the best working condition, thereby optimizing the effect of oil and gas recovery.
[0014] like Figure 1 As shown, on the basis of the above method, an oil outlet meter 13 is further provided on the quick oil outlet pipe 12. During implementation, the amount of oil and gas exported from the oil and gas temporary storage box 6 can be accurately measured, which is convenient for quantitative management of the reuse of recovered oil and gas, and can also reflect the operating efficiency and effect of the oil and gas recovery system. The oil and gas recovery hose 2 ensures the normal operation of the oil and gas recovery system and the effective recovery of oil and gas, enhances the fine control ability of the oil and gas recovery process, and is conducive to achieving more efficient recovery and utilization of oil and gas resources.
[0015] like Figure 1 As shown, on the basis of the above method, a pressure sensor 14 is further arranged on the side of the oil and gas recovery hose 2 to monitor the temperature and pressure changes in the oil and gas recovery process in real time. During implementation, the pressure sensor 14 arranged on the side of the oil and gas recovery hose 2 can monitor the temperature and pressure changes in the oil and gas recovery process in real time, provide important reference data for operators, and ensure the safety and stability of the recovery process.
[0016] In the specific working process of the novel oil and gas recoverable automobile refueling pipe assembly, first, when the automobile starts to refuel, the refueling equipment delivers gasoline to the automobile's fuel tank through the oil pipeline. At the same time, the oil and gas mixture generated during the refueling process is collected through the oil and gas recovery chamber 1 of the oil and gas recovery hose 2. This oil and gas recovery chamber is located inside the oil and gas recovery hose, is a key part of oil and gas recovery, and is responsible for effectively guiding and recovering the oil and gas mixture. As refueling proceeds, the oil and gas mixture in the oil and gas recovery hose 2 enters the adsorption separation device through the recovery gas pipe sealing groove 5. In this device, the adsorption material unit 7 composed of high-performance activated carbon or other materials with selective adsorption capacity will adsorb volatile gasoline vapor in the oil and gas mixture. At the same time, the filter 8 will further filter out impurities to ensure the quality of the recovered oil and gas. When the adsorption material unit 7 is saturated with adsorption, the vacuum pump 3 starts to work. It provides negative pressure to the desorber 9 so that the oil and gas adsorbed on the adsorbent material can be effectively desorbed. The desorbed oil and gas are transported to the oil and gas temporary storage box 6 for storage through the desorber 9. This process is achieved by adjusting and controlling the control valve 10. During the entire recovery process, the pressure sensor 14 on the side of the oil and gas recovery hose 2 will monitor the temperature and pressure changes during the oil and gas recovery process in real time, provide important reference data for the operator, and ensure the safety and stability of the recovery process. After refueling, the operator can export the recovered oil and gas in the oil and gas temporary storage box 6 through the quick oil outlet pipe 12 for reuse. The oil outlet meter 13 set on the oil outlet pipe can accurately measure the amount of exported oil and gas, which is convenient for quantitative management of the reuse of recovered oil and gas. In general, the new oil and gas recyclable automobile refueling pipe assembly realizes the effective recovery and reuse of the oil and gas mixture generated during the refueling process through the coordinated work of the oil and gas recovery chamber, the oil and gas recovery hose, the adsorption separation device, the vacuum pump and other components, thereby improving the utilization rate of resources and reducing environmental pollution.
