[0018] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0019] like Figures 1 to 6 As shown, a welding exhaust gas recovery pipeline includes a factory ceiling 1, and several support structures 2 are installed on the lower surface of the factory ceiling 1. The support structures 2 are used to support the recovery pipeline 3, which is used to recover welding exhaust gas in the factory.

[0020] The recycling pipe 3 includes a single-connection pipe 301, a two-connection pipe 302, a three-connection pipe 303, a suction hood 304, a transition pipe 305, and a fan 306. An opening is formed on the lower surface of the single-connection pipe 301, and the suction hood 304 is positioned directly below the opening and fixedly connected to the lower surface of the single-connection pipe 301. A two-connection pipe 302 is positioned on one side of the single-connection pipe 301, and two connections are respectively provided at both ends of the three-connection pipe 303. There is a two-way connecting pipe 302. One end of the two-way connecting pipe 302 is fixedly connected to the three-way connecting pipe 303, and the other end of the two-way connecting pipe 302 is fixedly connected to the one-way connecting pipe 301. The transition pipe 305 is square on the left and round on the right. The square side of the transition pipe 305 is fixedly connected to the three-way pipe, and the round side of the transition pipe 305 is fixedly connected to the fan 306. A purification mechanism 4 is provided on the rear side of the fan 306. The fan 306 and the purification mechanism 4 are fixedly connected by a connecting pipe.

[0021] Furthermore, an activated carbon filter 6 is installed inside the three-way connecting pipe 303. The activated carbon filter 6 is used to filter some dust in the exhaust gas, playing a preliminary filtration role.

[0022] The purification unit 4 includes a second connecting pipe 407, a heating copper pipe 401, a heater 402, a heat insulation layer 403, a heat insulation pipe 404, a pipe 405, and a chimney 406. One end of the second connecting pipe 407 is fixedly connected to the first connecting pipe 5, and the other end of the second connecting pipe 407 is fixedly connected to the pipe 405. The other end of the pipe 405 is fixedly connected to the chimney 406. A heat insulation layer 403 is installed inside the pipe 405, and a heating copper pipe 401 is installed inside the heat insulation layer 403. A heater 402 is installed on the outside of the pipe 405 and is mounted on the upper surface of the factory ceiling 1. A heat insulation pipe 404 is fixedly connected to the outside of the pipe 405. Both ends of the heating copper pipe 401 extend from the heat insulation layer 403 and the inside of the pipe into the heat insulation pipe 404, and both ends of the heating copper pipe 401 are fixedly connected to the heater 402. Heater 402 heats copper pipe 401 to the required temperature, keeping the insulation layer 403 at a high temperature. Insulation layer 403 retains most of the heat, keeping the outside temperature of pipe 405 at a safe level. However, when the filtered exhaust gas passes through this high-temperature pipe 405, harmful substances in the exhaust gas are directly decomposed at high temperature and finally discharged through chimney 406 by fan 306. The function of insulation pipe 404 is to prevent workers from accidentally touching the heating copper pipe 401 and getting burned. Connecting pipe 407 is a pipe compensator, which can compensate for the thermal expansion and contraction of pipe 405 caused by temperature changes, absorb the deformation of pipe 405 caused by long-term high temperature, and reduce the possibility of pipe 405 breaking due to insufficient space after thermal expansion.

[0023] Furthermore, a channel is provided on the pipe 405, and a cooling fan 7 is installed in the channel. A cover plate 10 is provided at the top of the channel, and one end of the cover plate 10 is hinged to the channel. A motor 11 is provided on one side of the channel. The output shaft of the motor 11 is fixedly connected to the cover plate 10, and the center of the output shaft of the motor 11 is concentric with the center of the hinge between the cover plate 10 and the channel. The motor 11 is installed on the channel. A signal receiver 8 is installed on the motor 11 and the cooling fan 7 respectively. A temperature detection module 9 is installed in the insulation layer 403. When the temperature in the insulation layer 403 exceeds a certain level, the temperature detector will send a signal. After receiving the signal, the signal receivers 8 on the motor 11 and the cooling fan 7 will start the motor 11 and the cooling fan 7. The motor 11 starts to open the cover plate 10, and the cooling fan 7 exhausts air to reduce the temperature in the insulation layer 403 to a reasonable range.

[0024] Working principle of the utility model: The fan 306 draws air into the pipe 405. Welding exhaust gas and dust in the factory enter the pipe 405 through the suction hood 304. Under the action of the fan 306, the exhaust gas and dust pass through the first connecting pipe 301, the second connecting pipe 302, and the third connecting pipe 303 in sequence. When passing through the third connecting pipe 303, the activated carbon adsorption mesh in the third connecting pipe 303 can perform preliminary filtration of dust and exhaust gas. Then, the fan 306 sends it into the purification mechanism 4 for further purification before it is discharged. This not only absorbs welding exhaust gas, greatly reducing the concentration of exhaust gas in the factory, but also filters and discharges welding exhaust gas, protecting the environment.
