Device for preventing sullage pipe from spraying residue

The utility model discloses a device for preventing sullage pipe from spraying residue, which comprises a boiler sullage pipe (1), a residue cooler water pocket inlet (2) and fireproof materials (5), wherein the joint of the boiler sullage pipe (1) and the residue cooler water pocket inlet (2) is connected with a water pocket gland (3), and is sealed by the fireproof materials (5). Materials of the water pocket gland (3) are the same as that of the boiler sullage pipe (1), and the materials have the same expansion coefficient. And therefore, when the inner diameter of the water pocket gland is basically the same as the outer diameter of the boiler sullage pipe, high-temperature waste residue can not be leaked out from the water pocket gland and the boiler sullage pipe. Compared with the prior art, with the technical proposal, the boiler sullage pipe and the residue cooler water pocket inlet are effectively sealed, which avoids the phenomenon that high-temperature residues of boilers are outwards ejected, and
