Embodiment 2

[0028] A domestic waste pyrolysis combustion furnace and its operating process, comprising the following steps:

[0029] 1) After the material enters the silo, it enters the pyrolysis gasification furnace evenly through the rotating distributor at a speed of 9-12 tons / h, opens the primary air supply system, and passes through the primary air to control the temperature in the pyrolysis gasification furnace The temperature is 500-700°C. The material is dried sequentially from the top to the bottom of the pyrolysis gasification furnace, pyrolysis gasification, surface combustion, carbon combustion, and finally until it is burnt into slag and cold slag, it is discharged from the body through the ash hopper. Simultaneously produce combustible gas, the pressure sensor P 2 The control is -30~-50Pa, the pressure sensor P 1 1-20Pa, pressure sensor P 1 5-10Pa;

[0030] 2) The air flow of the combustible gas rises to the pyrolysis smoke exhaust port on the upper part of the pyrolysis ...

Abstract

The invention provides a household garbage pyrolysis combustion furnace which is a vertical sleeve furnace. A furnace body is composed of a cylindrical pyrolysis gasification hearth and a secondary combustion chamber surrounding the hearth. Five isolation walls are arranged in the secondary combustion chamber. The secondary combustion chamber is divided into a secondary combustion hearth I, a secondary combustion hearth II, a secondary combustion hearth III, a secondary combustion hearth IV and a secondary combustion hearth V. The secondary combustion hearth III corresponds to a smoke outlet. The secondary combustion hearth I, the secondary combustion hearth II, the secondary combustion hearth IV and the secondary combustion hearth V are each internally provided with a lattice wall. Each lattice wall is provided with a plurality of smoke flowing through holes with unequal diameters. The outer side in the secondary combustion chamber is further provided with three secondary wind supply systems. The inner side wall of the secondary combustion hearth I and the inner side wall of the secondary combustion hearth V are each provided with a pyrolysis smoke outlet. The smoke flowing state is a layer flow state and a turbulent flow state which are implemented many times to participate in and interfere with secondary wind appropriately, a stable platform is provided for energy conversion of smoke discharged by the pyrolysis gasification process stage and decomposition and purification of harmful substance, and thus the quality index of waste treatment of the discharged smoke is increased greatly.

Description

technical field [0001] The invention relates to a large-capacity vertical sleeve garbage incinerator, in particular to a domestic garbage pyrolysis combustion equipment and a domestic garbage pyrolysis combustion operation process. technical background: [0002] The goal of municipal solid waste disposal is "harmless, reduced and resourceful", which has become the basic principle followed by all countries. It is an effective way recognized by all countries in the world to realize the heat treatment process of "harmless, reduction and recycling" of waste. According to different implementation conditions, the heat treatment process of domestic waste can be divided into three different processes: direct incineration, pyrolysis gasification and pyrolysis combustion. With the enhancement of people's awareness of environmental protection, the mechanical grate furnace is a typical direct waste incineration disposal process. In order to improve its flue gas emission indicators, the...
