To achieve the above object, present invention employs following technical scheme：After described waste heat boiler uptake flue wall with
Downward-flow flue front wall junction abrasion-proof structure, after waste heat boiler uptake flue on wall and downward-flow flue front wall junction tube wall between
Every covered with some Λ shapes bending plates, wall is with declining after Λ shapes bending plate is fixed on waste heat boiler uptake flue by bindiny mechanism
On the tube wall of flue front wall junction, on the outer wall of one of Λ shapes bending plate in per adjacent two pieces of Λ shape bending plates respectively
It is provided with a Λ shape bending bar that can cover gap between two pieces of Λ shape bending plates, all Λ shapes bending plate and Λ shape bending bars
It is collectively forming one layer of scuff-resistant coating that wall and downward-flow flue front wall junction tube wall after waste heat boiler uptake flue can be completely covered.
Further, wall and downward-flow flue front wall junction abrasion-proof structure after foregoing waste heat boiler uptake flue, wherein：
The structure of bindiny mechanism is：Some positioning round steel are fixed with wall after uptake flue, are provided with Λ shape bending plates some
The mounting hole corresponding with positioning round steel, Λ shapes bending plate is by the way that mounting hole is buckled on corresponding positioning round steel to hang over waste heat
After boiler uptake flue on wall and downward-flow flue front wall junction tube wall, and corresponding to being buckled in when the mounting hole of Λ shape bending plates
After positioning on round steel, one piece of limiting plate for being more than mounting hole is also welded with respectively in the outer end of each positioning round steel, by spacing
Plate by Λ shape bending plates it is spacing be fixed on after waste heat boiler uptake flue wall with the tube wall of downward-flow flue front wall junction.
Further, wall and downward-flow flue front wall junction abrasion-proof structure after foregoing waste heat boiler uptake flue, wherein：
Gap is 10mm between adjacent two pieces of Λ shape bending plates.
The implementation of Pass through above-mentioned technical proposal, the beneficial effects of the invention are as follows：（1）Pass through all Λ shapes bending plates and Λ shapes
The anti-of wall and downward-flow flue front wall junction tube wall after waste heat boiler uptake flue is completely covered in be collectively forming one layer of bending bar
Layer is ground, high-temperature dust-containing flue gas is avoided and directly washes away wall and downward-flow flue front wall junction tube wall after uptake flue, so as to effectively
With downward-flow flue front wall junction tube wall abrasion and dust stratification accumulated slag occur for wall after preventing uptake flue, ensure that nonferrous smelting waste heat
Boiler it is safe for operation；（2）Λ shape bending bars are welded on one of Λ shapes bending plate in adjacent two pieces of Λ shape bending plates
On outer wall, so that expansion clearance can be left between adjacent Λ shapes bending plate, nonferrous smelting waste heat boiler is further ensured
It is safe for operation.
