Vertical pyrolysis gasifier

Abstract

A vertical pyrolysis gasifier comprises a feeding mechanism, a flow guiding tube of a slag extractor, a sealing mechanism, a working region and a stirring mechanism, wherein the flow guiding tube communicates with a water jacket to form backflow; the sealing mechanism comprises a first sealing door and a second sealing door; the second sealing door is arranged at a V-shaped projection of the upper end of a gasifier body; the first sealing door and the second sealing door cannot be opened simultaneously; the working region comprises a drying region, a pyrolysis gasification region and a burning region; a smoke outlet is formed in the gasifier body and positioned in the upper end of the drying region; the stirring mechanism comprises a slag discharging plate and a stirring plate; the slag discharging plate and the stirring plate are arranged on the same rotating shaft; and a hollow structure which communicates with the outside is arranged in the rotating shaft. The vertical pyrolysis gasifier not only is good in sealing performance and high in work efficiency, but also improves a security environment of operators of a workshop, and avoids hidden danger of gasifier explosion caused by blockage of pyrolysis gas flow.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a vertical pyrolysis gasifier. technical background [0002] Resources and environment are the two major themes in the 21st century, and municipal solid waste disposal is an important subject in these two themes. With the enhancement of people's awareness of environmental resources, the governments of various countries have improved the technical standards of waste disposal, and the traditional main methods of waste disposal, landfill, composting, and incineration have increasingly shown their defects. The treatment capacity is small, the efficiency is low, and the incineration method is prone to secondary pollution, especially the pollution of Dioxins, which hinders its industrial application. Garbage pyrolysis technology has the characteristics of less secondary pollution, complete harmlessness, and high degree of resource utilization. It is one of the...
