Description

Technical Field

[0001] This utility model relates to the field of online detection technology for oil and gas recovery, and specifically to an online detection mechanism for oil and gas recovery in an oil depot oil and gas recovery treatment device. Background Technology

[0002] Oil and gas recovery and treatment devices can effectively collect and treat volatile organic compounds (VOCs) generated during the loading, unloading, and storage of oil depots, significantly reducing the emissions of these harmful substances. This improves air quality and reduces the formation of secondary pollutants such as photochemical smog and ozone. VOCs are important precursors to urban haze and photochemical smog, participating in the formation of ozone and secondary aerosols in the atmosphere, and have a significant impact on regional atmospheric ozone pollution and PM2.5 pollution.

[0003] A search revealed that CN212008506U discloses an online automatic detection device for oil and gas recovery. This device, with its disassembly and assembly mechanism, utilizes sensors to automatically detect oil and gas in the air, reducing the workload for operators. Rotating the sensor moves a locking block from a slide groove into its recess, allowing the sensor to be removed for cleaning or replacement, effectively extending its lifespan and preventing a decrease in detection efficiency. A support mechanism, via a movable shaft, allows the support plate to fold with the base, reducing the space occupied by the support mechanism. Rotating the support plate until fully open and turning the handle allows the fixed base to align with the ground, ensuring stability in various ground conditions. A servo motor drives a gear to rotate a connecting plate, which in turn causes the oil extraction port to rotate, improving both the sensor's detection performance and the overall oil and gas recovery efficiency of the oil and gas recovery unit.

The specific defects and shortcomings are as follows: The online automatic detection device for oil and gas recovery mainly places the sensor directly in the external environment, and the air flow direction cannot be controlled, which leads to certain limitations in the detection results, resulting in a low oil and gas recovery rate in the oil depot. Therefore, it is necessary to design an online detection mechanism for oil and gas recovery in the oil depot to solve the problems mentioned in the background technology. Utility Model Content
