The big footpath section bore of antipriming pipe is φ 5 ~ φ 10mm, wall thickness 1 ~ 5mm, and length overall 50 ~ 100mm, path section bore are φ 3 ~ φ 7mm.
The circular flat board that strongback is made for the heating resisting metal material, thickness of slab 8 ~ 20mm, the plate periphery welds with the awl tube.
Pilot hole on the strongback is corresponding with antipriming pipe; This pilot hole is concentric(al) circles and arranges.
On the strongback also the gap location at each pilot hole evenly arrange several perforates, aperture φ 10 ~ φ 30mm.
The quantity of antipriming pipe is 500 ~ 2000.
The circular flat board that grid distributor is made for the heating resisting metal material, thickness of slab 10 ~ 30mm, the plate periphery welds with the awl tube.
It is corresponding with antipriming pipe that grid distributor is provided with pilot hole; Pilot hole is concentric(al) circles and arranges.
The sieve aperture tringle is set in antipriming pipe, and the big footpath section of sieve aperture tringle and path section are corresponding with big footpath section and the path section of antipriming pipe; The big footpath section of sieve aperture tringle and antipriming pipe is transition fit, and the path section of sieve aperture tringle and antipriming pipe is running fit.
The path section of sieve aperture tringle and antipriming pipe is that the class of precision of running fit is IT9 ~ IT12.
Chlorine enters from the grid distributor below during fluidizing furnace operation, is evenly distributed to antipriming pipe, and evenly sprays into burner hearth from the sieve aperture back segment, with the furnace charge fluidization.
Compared with prior art, the present invention makes simply, low price, and use properties is stable, high life, quality product and production capacity are guaranteed, operational safety, operation and maintenance cost are low.
