Vertical daily garbage incinerator

Abstract

This invention provides a standing type domestic garbage incinerator which is fit for automatic control and can work steady for long time in gasifying condition. It includes first and second combustion furnaces communicated by smoke pipe. Charging opening is arranged at the center of the furnace body coping of first combustion furnace. Ring shaped smoke collecting channel is arranged at the top end of the furnace body lateral wall. The channel and the charging opening have the same axle. Several smoke outlet channels communicating the hearth and smoke collecting channel are arranged evenly along circumference direction on the coping of furnace body. The horizontal ring shaped smoke channel of first combustion furnace has several smoke outlet openings. They are evenly distributed along thecircumference of furnace coping. It increases the section and reduces the speed of smoke. The floater and dust inside of the hearth are not easy to be absorbed into the smoke channel. The ring shapedsmoke channel is convenient to repair and clean. This invention also has electric signal input required by self control. The automatic combusting control is fulfilled by adding electric control charging, slag discharging, first air supplying, second air supplying and air guiding.

Description

technical field [0001] The invention relates to the technical field of environmental protection, more specifically, it relates to a domestic garbage gasification incinerator with a primary combustion furnace and a secondary combustion furnace. Background technique [0002] At present, domestic waste incinerators are divided into mechanical grate incinerators, fluidized bed incinerators and gasification incinerators. The incineration principle of the garbage gasification incinerator is: first thermally decompose the garbage into combustible gas and solid residue mainly composed of charcoal in a reducing atmosphere of 450-600 °C, and then burn it. In order to suppress harmful substances such as dioxins, gasification treatment of domestic waste technology was first developed in Europe, and almost all European gasification technologies were introduced to Japan and improved and put into Japanese and European markets. At present, the domestic use of gasification incinerators to t...

AI Technical Summary

Problems solved by technology

Due to the complex characteristics and high real-time requirements of the gasification process, it is difficult to stabilize the gasification condition for a long time only by manual operation

Also due to the lack of necessary instrument detection, the gasification incineration process control under automation cannot be realized
