Novel soot blower sleeve connecting structure

The invention discloses a novel soot blower sleeve connecting structure which comprises a shell and a sleeve assembly. The connecting position of the sleeve and the soot blower shell is completely sealed in a welding mode, so that gas leakage at the connecting position is prevented; the soot blower is internally divided into two sleeve assemblies, the two sleeve assemblies are arranged in a spaced mode, outer pipes of one part of the sleeve assemblies extend, inner pipes of the other part of the sleeve assemblies extend into the extending outer pipes, and the sleeves are prevented from being heated to droop through mutual supporting of the structures of the sleeve assemblies. A certain distance is formed between the extended outer pipe and the other part of the outer pipe and between the extended inner pipe and the other part of the inner pipe, so that the problem of thermal expansion stress of the sleeve is solved; the outer pipes of the two parts are connected through the inner communicating pipe, and the t
