Urban garbage incinerating boiler

Abstract

The invention provides a closed type urban garbage incinerating boiler for incinerating urban garbage, which comprises a boiler body, a water tank, a combustion chamber and a fly ash outlet, wherein the combustion chamber is provided with an incinerating plate, the width of the incinerating plate is consistent with the width of the combustion chamber, the groove type incinerating plate divides the combustion chamber into a combustion cavity and a combustion-supporting cavity and is provided with through holes, and introduced mixed oxygen passes through the combustion-supporting cavity and enters into the combustion cavity through the through holes on the incinerating plate to support the combustion of the garbage dried by a drier. The combustion temperature of the incinerating boiler can reach above 850 DEG C; the incineration of the garbage can be controlled over 2 seconds; the production of dioxins and furans can be effectively inhibited; and produced fly ash (smoke) can only be discharged out of the fly ash outlet, so that convenience is provided for the treatment of the fly ash.

Description

technical field [0001] The invention relates to an incineration boiler used for incinerating urban garbage, in particular to an incineration boiler capable of fully burning urban garbage in a closed environment. Background technique [0002] Municipal waste includes domestic waste and medical waste. The existing municipal waste (hereinafter referred to as garbage) is mostly incinerated by a waste incinerator with a grate. After incineration, slag and fly ash are produced. The fly ash contains dust particles and harmful substances. The gas is discharged after being treated by the flue. The existing waste treatment equipment has the following disadvantages: due to the mechanical design of the grate, the incinerator cannot be closed, and the harmful gas in the fly ash will inevitably be discharged during incineration; secondly, the incineration temperature is low, the waste is not fully burned, and dioxins Harmful substances cannot be effectively suppressed; thirdly, the grate...

AI Technical Summary

Problems solved by technology

The existing waste treatment equipment has the following disadvantages: due to the mechanical design of the grate, the incinerator cannot be closed, and the harmful gas in the fly ash will inevitably be discharged during incineration; secondly, the incineration temperature is low, the waste is not fully burned, and dioxins Harmful substances cannot be effectively suppressed; third, the grate with mechanical transmission is used for a long time and the maintenance work is heavy

Fourth, because the incinerated garbage contains a lot of organic matter and high water content, the incineration is not sufficient, the amount of harmful gas produced is large, and the environment is polluted.
