A slag guide hole 18 is obliquely opened at the outer wall abutting the outer wall, and the residue cleaned by the cleaning brush 16 is introduced into the slag storage box 13. The bottom side of the cleaning brush 16 is close to the top of the filter plate 19, and the slag guide hole 18 is close to the outer side of the cleaning brush 16. The bottom end of the steam inlet pipe 2 is connected with the top of the filter box 7 through penetration, one end of the serpentine heat exchange metal pipe 6 is connected with the bottom of the filter box 7 through penetration, and the other end of the serpentine heat exchange metal pipe 6 penetrates the bottom right side of the box body 1 and is connected to the exhaust pipe 5.
