Abstract

The invention discloses a gasification incinerator and a waste gasification incineration method. The gasification incinerator comprises a first incinerator body and a second incinerator body. The first furnace body comprises a gasification section and a combustion section, and the second furnace body comprises a quenching section. And the tops of the first furnace body and the second furnace body are communicated and share a wall surface. A primary air distribution device is arranged at the bottom of the gasification section, a pre-combustion section and a secondary air distribution device are arranged at the side part of the gasification section, the pre-combustion section comprises a liquid feeding device, a solid feeding device and a combustion device, an outlet of the pre-combustion section is communicated to the upper section of the gasification section, and a steam inlet is formed in the lower section of the gasification section. The bottom of the combustion section is communicated with the top of the gasification section, and a tertiary air distribution device is arranged on the side portion of the combustion section. The top of the quenching section communicates with the top of the combustion section, and the quenching section is provided with a cooling water inlet, a smoke outlet and a fly ash outlet. When the gasification incinerator is used for treating waste materials, the waste material incineration and tail gas treatment effects can be remarkably improved, and the operation energy and labor cost can be remarkably reduced.

Description

technical field [0001] The invention relates to the field of gasification combustion, in particular, the invention relates to a gasification incinerator and a waste gasification incineration method. Background technique [0002] Existing waste incinerators mainly include direct-fired incinerators (such as fixed bed incinerators, fluidized bed incinerators, rotary kiln incinerators, etc.), gasification incinerators (such as fluidized bed gasification incinerators) and moving bed gasification incinerators, etc.) and pyrolysis incinerators (such as vertical rotary furnaces, fixed bed pyrolysis incinerators, etc.) and other furnace types. For direct-fired incinerators, fixed-bed incinerators are suitable for particularly small-scale occasions (such as a daily processing capacity of 1 to 2 tons), and the operation is inconvenient, requiring manual slag removal, which is unsafe. Fluidized bed and rotary kiln are suitable for large-scale incineration equipment, such as a daily pro...
