| description | The utility model discloses an anti-abrasion device which comprises an air preheater pipe, an air preheater pipe plate, a fixing pipe and an anti-abrasion sleeve. The air preheater is characterized inthat a fixed pipe is welded on a pipe plate of the air preheater; then, the wear-resistant sleeve is directly inserted into the fixed pipe in the mounting process; Such a structure is simpler to install, Mainly, the wear-resistant sleeve is more convenient to replace; Due to the fact that the number of the anti-abrasion casing pipes is very large, the anti-abrasion casing pipes need to be replaced after the boiler runs for a period of time, the anti-abrasion casing pipes can be rapidly pulled out of the fixing pipe in the replacement process of the anti-abrasion device, refractory castable does not need to be removed, and only the replaced anti-abrasion casing pipes need to be inserted. Due to the structure of the anti-abrasion device, the problem of replacing the anti-abrasion sleeve isgreatly solved, the labor |
