A garbage pyrolysis gasifier

Abstract

The invention discloses a garbage pyrolysis gasification furnace. A base of a furnace body is arranged in an ash pan. An air and steam inlet channel is formed in the center of the ash pan. An air and steam inlet of the air and steam inlet channel communicates with the interior of the garbage pyrolysis gasification furnace. An air and steam outlet is formed in the top end of the air and steam inlet channel, and the lower end of the air and steam inlet channel is connected with an air blower. A pyrolysis gasification chamber in the garbage pyrolysis gasification furnace is provided with an ash layer, a combustion gasification chamber, a destructive distillation layer and a drying layer from bottom to top. The combustion gasification chamber is provided with an ignition opening. A pyrolysis gasification gas outlet is formed in the drying layer and is connected with a secondary combustion chamber. A feeding opening is formed in the top of the garbage pyrolysis gasification furnace. A scraper is welded to the ash pan, the ash pan is driven by a motor to rotate, ash entering the ash pan is brought out by the scraper, and two rows of small gas holes are formed in the two sides of the scraper. According to the garbage pyrolysis gasification furnace, the optimal efficiency of garbage pyrolysis gasification can be achieved, and the garbage pyrolysis gasification furnace is more economical and environment-friendly.

Description

technical field [0001] The invention belongs to the field of solid waste treatment and resource utilization, and in particular relates to a garbage pyrolysis gasifier. Background technique [0002] At present, there are four main ways to deal with urban waste in various countries in the world: landfill, composting and incineration, and pyrolysis and gasification. Landfill treatment covers a large area, and the leachate and odorous gas produced by it will cause serious secondary pollution to the soil, groundwater and surrounding air environment, and damage the ecological environment; composting technology requires pre-treatment of garbage, requiring high organic matter The composting process needs to occupy a large area of ​​land, and at the same time, polluting gases and leachate will be produced. Improper treatment will cause serious environmental pollution; the essence of incineration is to oxidize organic waste into inert waste under high temperature and sufficient oxygen...

AI Technical Summary

Problems solved by technology

Landfill treatment covers a large area, and the leachate and odorous gas produced by it will cause serious secondary pollution to the soil, groundwater and surrounding air environment, and damage the ecological environment; composting technology requires pre-treatment of garbage, requiring high organic matter The composting process needs to occupy a large area of ​​land, and at the same time, polluting gases and leachate will be produced. Improper treatment will cause serious environmental pollution; the essence of incineration is to oxidize organic waste into inert waste under high temperature and sufficient oxygen supply conditions. Gaseous substances and inorganic non-combustible substances form stable solid residues. During incineration, a large amount of odorous, sulfur-containing and other toxic gases will be released. Dust and fine particles will fly with the wind, causing sulfur dioxide suspended particles in the air to exceed the standard, and frequent dust pollution caused by acid rain. Occurrence, and will produce a large amount of strong carcinogen dioxin, which is currently the main restrictive factor restricting combustion treatment
