[0050] As shown in the accompanying drawings for Figures 1-7 The utility model provides a technical scheme:

[0052] As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the recovery mechanism 3 is arranged in the separation tank 1 and the filter tank 2 for recovering oil gas in the oil gas storage tank 6, including a separation cylinder 301 arranged in the separation tank 1 and a first heat exchange pipe 302, the separation cylinder 301 is rotatably arranged in the separation tank 1 for separating oil gas by high-speed rotation of the separation cylinder 301, the first heat exchange pipe 302 is fixedly arranged on the inner side wall of the separation tank 1 and in contact with the outer wall of the separation cylinder 301 for heat exchange and condensation, condensing oil gas in the separation tank 1 and converting gaseous oil gas in the separation tank 1 into liquid; the recovery mechanism 3 further includes a filter assembly 309 arranged in the filter tank 2.

[0053] In the above description, the first heat exchange pipe 302 is arranged in the separation tank 1, and both ends of the first heat exchange pipe 302 extend through to the outside of the separation tank 1 and are in communication with the cooling fins 304 and the second heat exchange pipe 303, forming a closed-loop heat exchange pipe system for conveying heat exchange medium into the first heat exchange pipe 302 to cool the gaseous oil gas in the separation cylinder 301.

[0054] As shown in Figure 3 , Figure 4 and Figure 5 , the separation cylinder 301 is a cylindrical structure rotatably arranged on the side wall of the separation tank 1 and provided with a plurality of gas guide holes 310, the top opening of the separation cylinder 301 is in contact with the inner top wall of the separation tank 1 and is in communication with the conduit 308, the bottom is fixedly connected with the inner ring of the bearing 306, the bearing 306 is arranged on the inner top wall of the separation tank 1 and is connected with the servo motor 307 arranged at the bottom of the separation tank 1.

[0055] In the above description, the gas guide holes 310 are arranged obliquely on the side wall of the separation cylinder 301, during rotation of the separation cylinder 301 driven by the servo motor 307, gaseous oil gas entering the separation tank 1 through the liquid inlet pipe 101 spirally rises along the outer side wall of the separation tank 1 under the guidance and flow blocking of the first heat exchange pipe 302 (the first heat exchange pipe 302 is spirally arranged between the separation tank 1 and the separation cylinder 301), in the process of spirally rising of the gaseous oil gas, the gaseous oil gas is condensed into liquid under the action of the first heat exchange pipe 302 and flows downward along the first heat exchange pipe 302 to the bottom of the separation tank 1; at the same time, in the process of spirally rising of the gaseous oil gas, the gaseous oil gas gradually enters the separation cylinder 301 through the gas guide holes 310, under the high-speed rotation of the separation cylinder 301, centrifugal force is generated, the lighter gas in the oil gas is thrown to the center of the separation cylinder 301 and moves upward through the conduit 308 to be conveyed into the filter tank 2, the heavier liquid is thrown to the edge of the separation cylinder 301 and slides downward and falls through the bottom gas hole 310 to the bottom of the separation tank 1, and a liquid discharge port 102 for timed liquid discharge is arranged at the bottom of the separation tank 1;

When the gas in the separation tank 1 enters the filter tank 2 through the conduit 308, the oil gas is condensed by contacting the second heat exchange pipe 303, and is converted into liquid and recovered. When the oil gas is condensed by the two heat exchange pipes, the heat exchange medium in the first heat exchange pipe 302 and the second heat exchange pipe 303 can be circulated by the water pump 305, and is cooled by the heat sink 304.
