Description

Technical Field

[0001] The utility model relates to the technical field of waste gas and waste liquid treatment, in particular to a device for treating waste gas and waste liquid from petroleum well fracturing. Background Art

[0002] Fracturing is one of the important ways to improve the underground flow environment of oil. During the oil or gas extraction process, hydraulic force is used to form cracks in the oil and gas layers, thereby increasing the output of the oil well. Since waste gas and waste liquid will be generated during the fracturing process of oil wells, if they are directly discharged, they will cause pollution to the surrounding environment. Therefore, the waste gas and waste liquid need to be treated before discharge.

[0003] The existing waste gas and waste liquid treatment devices are not ideal for waste gas treatment. They only filter the particles in the waste gas through the filter layer. There are still a large number of harmful gases in the filtered waste gas. The harmful gases will be emitted into the air, which will not only cause the greenhouse effect and cause air pollution, but also pose a threat to the health of workers.

[0004] Therefore, we propose a device for treating waste gas and waste liquid from oil well fracturing. Utility Model Content
