Heat exchange pipeline cleaning shovel

Abstract

The invention discloses a heat exchange pipeline cleaning shovel. The heat exchange pipeline cleaning shovel comprises a shovel body and a handle. The shovel body is wholly in a tubular shape, an opening is formed in the tube wall of the shovel body, the length direction of the opening is consistent with the length direction of the shovel body, and a tip part is arranged on the end face of the shovel body. The shovel body is arranged to be of the tubular structure, the shovel body can conveniently enter the inner walls of multiple heat exchange pipelines to carry out cleaning, the opening is formed in the tube wall of the shovel body, cleared-way dirt can be conveniently discharged, dirt is prevented from being stacked in a tube cavity of the shovel body to cause blockage, and the tip partis arranged on the end face of the shovel body, and can be used for cleaning the hard attachment.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a cleaning shovel for heat exchange pipes of hot blast stoves. Background technique [0002] During the working process of the hot blast stove, high-temperature flue gas is generated by burning coal, biomass fuel, etc., and the high-temperature flue gas is passed into the heat exchange pipe to heat the heat exchange pipe. Lower the heat to form hot air. Among them, the heat exchange pipe realizes the heat exchange process between the high temperature flue gas and the cold air. [0003] Because during the fuel combustion process, the flue gas produced will contain ash and dust. When the flue gas passes through the heat exchange pipe, some dust will adhere to the pipe wall of the heat exchange pipe. After working for a long time, the heat exchange pipe will There will be more and more dust attached to the pipe wall, and the accumulation will make the cross-sectional area...

AI Technical Summary

Problems solved by technology

[0003] Because during the fuel combustion process, the flue gas produced will contain ash and dust. When the flue gas passes through the heat exchange pipe, some dust will adhere to the pipe wall of the heat exchange pipe. After working for a long time, the heat exchange pipe will There will be more and more dust attached to the pipe wall, and the accumulation will make the cross-sectional area of ​​the heat exchange pipe smaller, which will affect the passage of flue gas, resulting in low heat exchange efficiency

This requires cleaning the heat exchange pipes from time to time. In the current high-energy hot blast stove, the heat exchange pipes can be as long as six meters. The existing cleaning device obviously cannot clean the heat exchange pipes.
