[0028] A first discharge pipe 13 is provided with a first discharge cavity 14, in which a wind pressure assembly is fixedly arranged, an inlet pipe 19 is fixedly connected to the outer circumferential surface of the main body 11, and a plurality of heating wires 23 are fixedly connected to the upper arc surfaces of the first filter 21 and the second filter 22 with equal arcs with the axis of the first filter 21 as the axis core. Both the first filter 21 and the heating wires 23 are made of high temperature resistant metal filters. The heating temperature of the second filter 22 by the heating wire 23 exceeds 230 degrees Celsius, and the heating temperature of the first filter 21 by the heating wire 23 exceeds 120 degrees Celsius.

[0029] The rotating assembly includes a first rotating shaft 24 and a first limit block 25. One end of the first rotating shaft 24 is fixedly connected to the first filter 21, and the other end of the first rotating shaft 24 is rotatably connected to the first limit block 25. A plurality of first limit rods 26 are fixedly connected to the first limit block 25. The first limit rods 26 are fixedly connected to the outer circumferential surface of the exhaust gas treatment chamber 12. A motor 27 is arranged on the first limit block 25, and the output shaft of the motor 27 is fixedly connected to the first rotating shaft 24.

[0030] A plurality of first limit rods 26 are fixedly connected to the side surface of the first limit block 25 with the axis of the first rotating shaft 24 as the axis and an arc of equal arc. An opening is opened in the first limit block 25, and the output shaft of the motor 27 is rotatably connected to the opening of the first limit block 25. The wind pressure assembly includes a second limit block 30 and a second limit rod 31. The second limit rod 31 is fixedly connected to the outer cylindrical surface of the second limit block 30. The second limit block 30 is rotatably connected to the second rotating shaft 32. A plurality of fan blades 33 are fixedly connected to the outer cylindrical surface of the second rotating shaft 32. A condensation plate and an activated carbon adsorption plate are further provided on the first limit rod 26 to achieve cooling and comprehensive adsorption of the exhaust gas.

[0031] The condensation component includes a second discharge pipe 15 and an asphalt collecting box 16, one end of the second discharge pipe 15 is fixedly connected to the bottom end surface of the main body 11, and the other end of the second discharge pipe 15 is fixedly connected to the asphalt collecting box 16. A second discharge chamber 17 is opened in the second discharge pipe 15, and a condensation pipe 18 is fixedly arranged in the second discharge chamber 17. The first filter screen 21 and the second filter screen 22 are provided with guide grooves on the side surfaces close to the outer cylindrical surface of the exhaust gas treatment chamber 12, and a guide groove is provided on the outer cylindrical surface of the exhaust gas treatment chamber 12.

[0032] When the present scheme is used to treat asphalt waste gas, the asphalt waste gas to be treated is first charged into the waste gas treatment chamber 12 from the feed chamber 20. After the asphalt waste gas to be treated enters the waste gas treatment chamber 12, it rises in the waste gas treatment chamber 12. Then, when the asphalt waste gas to be treated passes through the second filter screen 22, the heating wire 23 on the second filter screen 22 heats the asphalt waste gas to be treated to more than two hundred and thirty degrees Celsius, so that the asphalt crystals in the asphalt waste gas melt and mix into the asphalt waste gas and rise. Since the motor 27 drives the first rotating shaft 24 to rotate, the first rotating shaft 24 drives the second filter screen 22 to rotate, and part of the asphalt liquid flows along the inclined surface and the guide groove of the second filter screen 22 along the guide groove on the outer cylindrical surface of the waste gas treatment chamber 12 to the bottom of the waste gas treatment chamber 12.

[0033] When the melted asphalt and asphalt waste gas rise to the first filter 21, the motor 27 drives the first rotating shaft 24 to rotate, and the first rotating shaft 24 drives the first filter 21 to rotate. Since the temperature of the first filter 21 is lower than that of the second filter 22, the asphalt liquid adheres to the first filter 21 and flows along the inclined surface and guide groove of the first filter 21 along the guide groove on the outer cylindrical surface of the waste gas treatment chamber 12 to the bottom of the waste gas treatment chamber 12. Finally, the asphalt liquid enters the asphalt collection box 16 after the condensation effect of the condenser 18. After the asphalt waste gas is cooled and adsorbed by the filter plate, most of the organic matter and harmful gases, especially the difficult-to-treat substances such as polycyclic aromatic hydrocarbons, have been adsorbed. The waste gas is subsequently discharged from the first discharge chamber 14, and then the discharged waste gas is catalytically oxidized to desorb the saturated activated carbon. The desorbed organic waste gas is decomposed into carbon dioxide and water through catalytic oxidation technology, and finally, it is sent to the smelting furnace by advanced oxidation processes such as plasma technology and photocatalytic oxidation.
