Abstract
The utility model provides pipeline solid waste cleaning equipment which comprises an air preheater, and the air preheater comprises a shell and a double-layer heat exchange tube bundle. Two soot blowing assemblies of the same structure are arranged on the side portion of the shell and used for removing soot of the double-layer heat exchange tube bundle. The soot blowing assembly comprises a communicating pipe, a valve, a transverse pipe and a blowing nozzle; one end of the communicating pipe is communicated to the steam output end, and the other end of the communicating pipe is connected with the transverse pipe; the end part of the transverse pipe is connected with a plurality of blowing nozzles, and each blowing nozzle is matched with the heat exchange pipe bundle; the communicating pipe is inserted into and slidably connected with the shell, and a valve is installed in the communicating pipe. The pipeline solid waste cleaning equipment is mainly used for cleaning a heat exchange tube bundle of a boiler air preheater, and dust or solid waste generated after dust caking can be removed by introducing steam into the heat exchange tube bundle; the heat exchange tube bundle can be effectively prevented from being blocked, and the operation efficiency of the boiler is improved. In addition, the boiler can be cleaned even if the boiler is not shut down, and meanwhile the cleaning efficiency is high.
