[0002] Oil and gas recovery refers to the process of collecting and treating oil and gas generated during the loading and unloading of gasoline in the storage, transportation and sales links. Specifically, oil and gas recovery includes oil and gas recovery at gas stations and oil depots. At gas stations, oil and gas recovery devices can effectively capture VOCs oil and gas emitted during refueling, and convert gaseous oil and gas into liquid gasoline through absorption, adsorption or condensation processes, thereby realizing resource reuse and reducing environmental pollution. Oil and gas recovery not only contributes to environmental protection and energy conservation, but also has important significance for public safety and resource conservation. In order to reduce environmental pollution and save energy at the same time, an oil and gas recovery device is needed. However, existing oil and gas recovery devices still have the following shortcomings:

[0003] When existing oil and gas recovery devices are used, most of them use liquid level detectors to avoid oil spills. However, if the liquid level detector fails or is not properly monitored, the oil tank is prone to oil spills, which not only causes waste of oil products, but also easily leads to secondary accidents such as fire, oil and gas poisoning and environmental pollution, resulting in reduced practicality and efficiency of the oil and gas recovery device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an oil and gas recovery device with an anti-overflow structure is proposed. Utility Model Content
