Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the attached drawings. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Example 1

Referring to fig. 1 to 2, the embodiment provides a tubular air preheater with a dust removing function, which includes a housing 2, a smoke tube 1 is vertically disposed in the housing 2, an air inlet pipe 6 is disposed at an upper portion of one side of the housing 2, and an air outlet pipe 7 is disposed at a lower portion of one side of the housing 2. The lower part of the tubular air preheater is provided with a flue gas inlet flue 4, and the upper part is provided with a flue gas outlet flue 5.

A set of ash removal component 3 is installed in each smoke pipe 1, the ash removal component 3 is composed of end connection hinges and serially connected ash scraping metal rings, the upper ends of the ash removal components 3 are respectively fixed on wing plates of a driven shaft 9 and a driving shaft 10 through pin shafts, and the driven shaft 9 and the driving shaft 10 are installed on the outer wall of a smoke outlet flue 5 of the tubular air preheater through a bearing seat 11.
