Abstract

The invention relates to a three-dimensional hierarchical air supply combined waste incinerator, in particular to a waste incinerator. The waste incinerator provided by the invention solves the problems of single function and narrow application range of the traditional waste incinerator. In the waste incinerator provided by the invention, the lower end of a feeding device is communicated with one end of a rotary drying pyrolysis device; the other end of the rotary drying pyrolysis device is communicated with a grate type incinerator; the feeding device and the rotary drying pyrolysis device are fixedly installed on a first bracket; two groups of secondary air spray pipes are both communicated with a secondary air main pipe; one group of the two groups of secondary air spray pipes is positioned above a rear arch and arranged on the outer side wall of a rear wall, and the other group of secondary air spray pipes are arranged at the lower end of a front wall; each group of secondary air spray pipes is communicated with a hearth; a high-temperature smoke interface is communicated with a horizontal flue through a pipeline; an intermediate-temperature smoke interface is communicated with a tail flue through a pipeline; and an air interface is communicated with the air outlet of an air preheater through a pipeline. The waste incinerator provided by the invention is used for incinerating waste.

Description

technical field [0001] The invention relates to a waste incineration device. Background technique [0002] With the development of the national economy and the improvement of people's living standards, human beings generate more and more waste in production, consumption, life and other activities. Waste has become an important factor of environmental pollution in our country, and it needs to be dealt with in a standardized manner. Waste treatment includes resource utilization, minimization of production and discharge, harmless treatment, etc. Among them, harmless treatment is the main waste treatment method adopted in my country at this stage. Among the harmless treatment methods, the incineration method is a technology that can simultaneously realize waste treatment reduction, harmlessness and resource utilization, and has been widely valued. [0003] Existing incinerators mainly include grate incinerators, fluidized bed furnaces, rotary kiln incinerators and liquid injec...
