[0002] With the development of the global economy and the increase in energy demand, the extraction, processing, storage and transportation of oil and natural gas are becoming more and more frequent. The emission of volatile organic compounds (VOCs) in oil and gas generated in these activities has become a serious environmental problem. VOCs not only affect the air quality, but also may lead to waste of resources. For this reason, many countries and regions have formulated strict environmental protection laws and regulations requiring effective control of oil and gas volatilization.

[0003] At present, there are many oil and gas recovery technologies on the market, including adsorption, condensation, membrane separation, etc. These technologies can reduce oil and gas emissions to a certain extent, but they generally have problems such as high cost, low efficiency, and complex maintenance.

[0007] Preferably, the sleeve is an externally threaded sleeve, and a spring is embedded in the side wall of the sleeve.

[0008] Preferably, an antistatic layer is provided on the inner wall of the tube sleeve.

[0009] Preferably, a butt joint is provided on the lower side of the top ring.

[0010] Preferably, a sealing ring is provided at the inner ring of the sealing ring.

[0011] Beneficial effects: The utility model proposes an oil and gas recovery dust cover, which is simple, practical and has a wide range of applications; a sealing head is arranged at the upper end thereof, a sealing ring is arranged on the sealing head, the sealing ring can seal the connecting pipe, and a rubber leather cover is arranged inside thereof, the rubber leather cover is tightly matched with the connecting pipe, and can effectively prevent dust from entering. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 Shows a schematic diagram of the structure of the utility model;

[0013] Figure 2 The internal structure diagram of the utility model is shown. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] like Figure 1~Figure 2 The oil and gas recovery dust cover shown in the figure includes: a pipe sleeve 1, a sealing head 5, the pipe sleeve 1 is an externally threaded sleeve, and a spring 12 is embedded in its side wall, an antistatic layer 11 is provided on the inner wall of the pipe sleeve 1, a top ring 3 and a bottom ring 2 are respectively provided at the upper and lower ends of the pipe sleeve 1, the inner diameter of the top ring 3 is smaller than the inner diameter of the pipe sleeve 1, a threaded connector 4 is provided on the top ring 3, the sealing head 5 is provided with an internal thread and is threadedly matched with the threaded connector 4, the sealing head 5 is screwed on the threaded connector 4, and since the connecting pipe is a tubular structure, the sealing head 5 is set as two semicircular clamps 6, side ears 9 are provided at both ends of the clamp 6, and screw holes are opened on the side ears 9, and the two clamps 6 can be docked and locked by bolts and nuts 10, and each sealing head 5 is provided with a semicircular sealing ring 7, and the inner ring diameter of the two sealing rings 7 after merging is smaller than the inner diameter of the top ring 3.

[0016] The connecting pipe is inserted from the top of the pipe sleeve 1 and passes through the pipe sleeve 1 to be installed in conjunction with the butt joint. At this time, the pipe sleeve 1 will cover the outside of the connection. In order to ensure the seal between the pipe sleeve 1 and the sealing head 5 and the butt joint, a sealing ring 8 is provided at the inner ring of the sealing ring 7, and multiple layers of sealing gaskets 14 are provided on the upper side of the top ring 3 and the lower side of the bottom ring 2; and a rubber sheath 13 is also provided in the threaded connector 4, and the diameter of the rubber sheath 13 gradually decreases from the fixed end to the distal end.
