s2: the sludge in the drying container (4) is crushed by the primary crushing mechanism (5) and the secondary crushing mechanism (7), moisture in the crushed sludge is evaporated by high-temperature gas, the moisture content of the sludge is reduced, meanwhile, water vapor is discharged to the outside of the drying container through the waste gas port (10), and the discharged waste gas is returned to the incineration tower through the waste gas recovery assembly (31);
s3: after the first-stage crushing mechanism crushes the sludge, the contact area and the sufficiency of the sludge and the high-temperature gas are increased, filter pressing concentration and mud cake forming are carried out through the mud cake forming mechanism after drying, and crushing and high-temperature gas drying treatment are carried out through the second-stage crushing mechanism (7).
