The fly ash in the dust collecting bottom plate 205 gradually increases, and when it reaches the maximum gravity set by the induction controller 206, the dust exhaust pipe 208 is opened to discharge the fly ash; the flue gas flows into the flue gas separation inner body 10 through the connecting pipe 3, and is impacted in the cross setting of the central baffle 9 and the outer ring baffle structure 11, thereby realizing solid-gas separation, part of the fly ash falls above the central baffle 9 and the outer ring baffle structure 11, and the other part is discharged from the fly ash discharge structure 5; the cleaning block 1209 slides back and forth between the central baffle 9 and the outer ring baffle structure 11 to clean the fly ash, and finally falls onto the first conveyor belt 1201 from the cleaning leak hole 14.
