S-type separable combustion-supporting life refuse incinerator

The utility model relates to an S-shaped separable combustion-supporting type incineration furnace for domestic refuse, which is formed by combining a big refuse combustion chamber, a bottom layer reciprocating grate furnace, a vertical combustion chamber, a refuse combustion chamber, a top layer secondary combustion chamber and a push rod feeding system, wherein the fume passes through each combustion chamber to present an S shape through connecting in series from the big refuse combustion chamber to a fume outlet, a piston push rod below a feed hopper pushes the refuse at the bottom into a pharynx opening of the incineration furnace through piston motion and the refuse is transported in the refuse combustion chamber to burn through a chain grate. The fume generated from the combustion of refuse in the combustion chamber enters the secondary combustion chamber and is mixed with the blowing hot air to burn again so as to ensure the complete oxidation of the organic gas generated during refuse burning, the burnt out slag and the unburnt slag fall in a bottom layer reciprocating grate after the combustion process of the vertical combustion chamber, the unburnt slag continuously burns on the reciprocating grate, and finally, the slag is pushed to a slag hoist through the motion of the reciprocating grate and is discharged with the slag of the big refuse together.
