The invention discloses a garbage incinerator with a built-in
chimney. The garbage incinerator comprises an incinerator body, a
combustion chamber, a feed hopper, a bracket and a
chimney, wherein the feed hopper is arranged above the incinerator body; the bracket is arranged in the middle of the incinerator body; the incinerator body and the bracket form the
combustion chamber; the
chimney is arranged at the top part of the bracket; the lower end of the chimney is arranged inside the feed hopper and the upper end is higher than the feed hopper; the incinerator body further comprises an automatic
water supply tank, an external
water pipe and a main
water pipe; the automatic
water supply tank is arranged on the external side of the incinerator body; the main
water pipe is arranged in the middle of each of the bracket and the chimney; the bottom end of the main water
pipe is communicated with the automatic
water supply tank through the external water
pipe; the top end of the main water
pipe is communicated with an exhaust annular pipe. The garbage incinerator is provided with the main water pipe and an internal water pipe, which are communicated with the automatic water supply tank outside; and in the
combustion process of garbage, a large amount of steam is formed and mist is formed above the incinerator body to settle the dust discharged from the chimney into the incinerator body, so that the
pollution from the dust to the environment is reduced; moreover, the garbage incinerator gains a better economic benefit and social benefit.
