Small gasifying incinerator

Abstract

The invention discloses a small gasifying incinerator. The small gasifying incinerator comprises a gasifying zone, a burning zone, a burning-out zone and a feeding device. The burning zone comprises afirst burning zone portion and a second burning zone portion which are arranged in an n shape. The first burning zone portion is disposed above the gasifying zone, and a uniformly-contracted throat is formed at the connecting position of the gasifying zone and the first burning zone portion. The burning-out zone communicates with the bottom of the second burning zone portion, and then a turn-backtype material flow channel is formed. A fire grate which is obliquely downward is disposed at the bottom of the gasifying zone, and air or water cooling is applied to the interior of the fire grate.A first air chamber is disposed at the bottom of the fire grate, and baffles are disposed in the first air chamber. A material falling channel is disposed at the tail end of the fire grate, and a water seal trough is disposed at the bottom of the material falling channel. A second air chamber is disposed outside the throat in an encircling mode, and communicates with the throat through secondary air openings and tertiary air openings. The secondary air openings are formed in the downward oblique surfaces of the throat, the tertiary air openings are formed in the upward oblique surfaces of thethroat, and the rotation direction formed by outflowing air of the secondary air openings is opposite to the rotation direction formed by outflowing air of the tertiary air openings. Materials are dried and gasified on the oblique fire grate of the small incinerator, so that the materials are reacted uniformly and stably, and the gasification rate and the burning-out rate are improved through reasonable air distribution.

Description

technical field [0001] The invention relates to a small-sized gasification incinerator, which is used for gasification and combustion of household garbage and other wastes, and belongs to the field of solid waste gasification and combustion. Background technique [0002] The resource utilization of household garbage and other wastes has been widely concerned. Pyrolysis or gasification, combustion has always been an important way of resource utilization of domestic waste. Due to the complex composition of domestic waste in my country and the high content of moisture and ash, there are often certain problems in the applicability of separate pyrolysis gasification or combustion. There is a combined waste incineration technology that uses grate feed drying and circulating bed combustion to enhance the adaptability of waste and obtain better waste treatment effects, but it is often suitable for large-scale waste incinerators. Contents of the invention [0003] The purpose of ...
