[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please refer to Figure 1-Figure 6 The embodiment of the utility model provides a coke oven gas combustion device, including a combustion shell 1, a hollow cylinder 4 is rotatably arranged in the combustion shell 1, convex pipes 5 are arranged on the upper and lower sides of the hollow cylinder 4, the convex pipe 5 is connected to the hollow cylinder 4, a plurality of nozzles 6 are arranged on the outer side of the convex pipe 5, the nozzles 6 spray out the gas, an igniter 21 is installed on the lower side of the convex pipe 5, the igniter 21 ignites the gas to make the gas burn.

[0030] Among them, the lower end of the hollow cylinder 4 passes through the lower end of the combustion shell 1 and is rotatably connected to the upper end of the connecting pipe 13. The lower end of the connecting pipe 13 is fixedly connected to the bottom of the combustion shell 1. The connecting pipe 13 is connected to an air intake pipe 14. The gas enters the hollow cylinder 4 through the air intake pipe 14. When the nozzle 6 sprays the gas, the hollow cylinder 4 can be rotated to spray, so that the gas is distributed more evenly.

[0031] At the same time, a shunt pipe 15 is connected to the air intake pipe 14, and one end of the shunt pipe 15 is connected to a compressor 19 through a pipeline. The compressor 19 can transport air to the inside of the combustion shell 1. A second valve 18 is installed on the pipeline connecting the compressor 19 and the shunt pipe 15. The second valve 18 controls the entry of air.

[0032] An exhaust pipe 16 is connected to the upper end of the combustion shell 1, and the air outlet of the exhaust pipe 16 is connected to the high-temperature fan 20. The air outlet of the high-temperature fan 20 is connected to the other end of the diversion pipe 15 through a pipeline. The exhaust gas generated inside the combustion shell 1 is sucked out by the high-temperature fan 20 and transported to the inside of the combustion shell 1 again through the pipeline, so that the exhaust gas is recycled and the utilization rate of resources is improved. In addition, a first valve 17 is installed on the pipeline connecting the high-temperature fan 20 and the diversion pipe 15, and the entry of the exhaust gas is controlled by the first valve 17.

[0033] In order to make the hollow cylinder 4 rotate, a gear plate 7 is arranged on the outside of the hollow cylinder 4 located outside the combustion shell 1, and a symmetrical gear 8 is rotatably arranged at the lower end of the combustion shell 1. The two sides of the gear plate 7 are respectively engaged with two gears 8. By rotating one of the gears 8, the gear plate 7 is rotated, thereby realizing the rotation of the hollow cylinder 4.

When the gear 3 12 rotates, the gear 2 11 and the gear 3 12 are meshed, and at this time, the gear 2 11 rotates with the gear 1 8.

[0035] Since a rotating fan 9 is rotatably arranged inside the combustion shell 1, and the lower end of the rotating fan 9 is connected to the upper end rotating shaft of the gear 8, when the gear 8 rotates, the rotating fan 9 is driven to rotate.
