Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, and more specifically, to an oil and gas evaporation emission collection device. Background Art

[0002] During the extraction, transportation, and processing of oil and gas, especially during the refueling process, a large amount of hydrocarbon gas emissions often occur. These gases not only pollute the environment but also represent a huge waste of energy. Therefore, oil and gas recovery technology has become an important part of the oil and gas industry, aiming to reduce environmental pollution and improve resource utilization efficiency.

[0003] Traditional methods are unable to effectively collect and process these emitted oil and gas, and most fuel hoses or fuel nozzles do not have oil and gas collection devices. Therefore, developing a simple and efficient oil and gas evaporation emission collection device is of great significance for reducing environmental pollution. Summary of the Utility Model

[0004] Based on the above technical problems, the utility model proposes an oil and gas evaporation emission collection device.

[0005] An oil and gas evaporation emission collection device includes: a gas collection hood and a recovery tank. The gas collection hood is sleeved on the oil pipe joint, and its rear end is sealed with the oil pipe joint, and its front end covers the outer wall of the inlet oil pipe. A connection seat is provided on the outer wall of the gas collection hood, and a connection head is provided on the connection seat, and the connection head is connected to the docking head at the front end of the oil and gas pipe. The rear end of the oil and gas pipe is connected to the oil and gas pump in the recovery tank. A recovery pipe is provided in the recovery tank. The oil and gas outlet pipe of the oil and gas pump communicates with the lower part of the front end of the recovery pipe. An oil and gas recovery device is provided at the upper part of the oil and gas rising section of the recovery pipe, and an oil molecule diaphragm is provided in the oil and gas recovery device. The end of the recovery pipe is an exhaust pipe, and the upper section of the exhaust pipe is located outside the recovery tank. A sealed oil collection tank is provided at the lower part of the recovery tank. Drain pipes are provided at the lowest point of each section of the recovery pipe, and the lower ends of the drain pipes communicate with the oil collection tank. An oil discharge pipe is provided on one side of the oil collection tank.

[0006] Preferably, the gas collection hood is a corrugated sleeve. A connecting pipe is rotatably connected to the lower end of the gas collection hood. The connecting pipe is in sealing cooperation with the gas collection hood. Internal threads are provided in the connecting pipe, and external threads are provided on the outer wall of the inlet oil pipe. The connecting pipe is in sealing cooperation with the inlet oil pipe.

[0007] Preferably, the recovery pipe is a vertically bent serpentine pipe, and the recovery pipe is arranged annularly along the inner wall of the recovery tank.

[0008] Advantageous Effects

[0009] 1. By putting the gas collecting cover on the oil pipe joint and ensuring that it is sealed with the oil pipe joint, the oil and gas evaporated between the oil pipe joint and the oil inlet pipe can be effectively collected to prevent the oil and gas from leaking into the environment;

[0010] 2. By connecting the rear end of the oil and gas pipe to the oil and gas pump in the recovery tank, rapid oil and gas transportation is achieved, reducing the residence time of oil and gas in the pipeline and reducing the risk of oil and gas leakage again;

[0011] 3. The vertically curved serpentine recovery pipe is arranged in a ring along the inner wall of the recovery tank, which increases the flow path length of the oil and gas in the recovery pipe and increases the number of times the oil and gas passes through the oil and gas recovery device, thereby improving the oil and gas processing efficiency;

[0012] 4. The oil drain pipe at the lowest point of each section of the recovery pipe is connected to the oil collecting tank, ensuring that the separated oil can be smoothly collected in the oil collecting tank and discharged through the oil unloading pipe, realizing efficient oil recovery and utilization.
