The temperature of the circulating gas passing through the primary dust remover is between 800 and 980 ℃, and the pressure is between-100 and-800 Pa, so that the refractory fiber cotton is filled between the refractory material of the high-temperature expansion joint and the expansion joint expansion body and in the expansion joint. Therefore, the coke dust is prevented from being deposited in the expansion joint, the high-temperature gas is prevented from directly contacting with the expansion joint telescopic body, and the service life of the expansion joint telescopic body is prolonged. Because the existing dry quenching engineering adopts a mode of directly filling the refractory cellucotton, although the refractory cellucotton is compacted during installation, the refractory cellucotton can be gradually pumped out in a negative-pressure high-temperature gas environment for a long time, and finally high-temperature gas burns through a telescopic body of a high-temperature expansion joint to cause equipment damage.
