Then, the gaseous cooling medium flows into the first baffle chamber 141 of the next stage, and is reflected by the first baffle chamber 141.

In this manner, the plurality of first and second refractive cavities 141 and 151 sequentially reflect the gas cooling medium. The multistage heat exchange between the gas cooling medium and the active coke is realized, the cooling rate and the cooling effect of the active coke are greatly improved, and the utilization rate of the gas cooling medium is improved.

In some embodiments, as shown in fig. 1, the active coke cooling device further includes a first pipe 3, a second pipe 4, a heat exchanger 5, and a third pipe 6, wherein a first end of the first pipe 3 is connected to the first joint, a first end of the second pipe 4 is connected to the second joint, and the driving device is mounted on the first pipe 3.
