Embodiment 1

[0072] figure 1 Schematically provides a schematic structural diagram of the waste pyrolysis incineration device of the embodiment of the present invention, as figure 1 As shown, the pyrolysis incineration device includes:

[0073] Feed bin 1, feeding channel 2, furnace body 3, fire grate 4 and secondary combustion chamber 6, the furnace body adopts a vertical converter; these parts and connection methods are all prior art in the art, and will not be repeated here;

[0074] At least two cavities 8, the at least two cavities 8 are arranged on the outlet side of the second combustion chamber; heat storage materials (such as ceramic pellets) are arranged inside or on the sides of the at least two cavities 8 , so that the heat carried by the gas discharged from the second combustion chamber 6 is partially retained in the material;

[0075] A pipeline 7, the input end of the pipeline 7 is connected to any one of the at least two cavities 8, and the output end is connected to the ...

Embodiment 2

[0118] An application example of the pyrolysis incineration device and working method according to Embodiment 1 in the pyrolysis gasification incineration of domestic waste.

[0119] In this application example, the furnace body adopts a conventional vertical converter.

[0120] image 3 Schematically provides the structural diagram of the fire grate and the pipeline of the present embodiment, as shown in 3, on the conical fire grate 4, four air distribution ducts 9 vertically upward are symmetrically arranged, and each air distribution duct The top of 9 is inclined downwards and is used to prevent slag from entering the exhaust port. Each air distribution duct 9 is provided with two exhaust ports, and the exhaust ports of the same height are symmetrically distributed, and the gas discharged from the exhaust ports flows to the area near the furnace wall in the furnace body. The height of the highest exhaust port is lower than the top of the grate. A slender channel is arran...

Embodiment 3

[0127] Application example of pyrolysis incineration device and working method according to embodiment 1 in domestic waste pyrolysis incineration.

[0128] In this application example, the furnace body adopts a conventional vertical converter.

[0129] Figure 4 A schematic structural diagram of the grate and pipes of this embodiment is given schematically. As shown in FIG. The top and middle sections of the 6 air distribution ducts are connected to form annular ducts at the same height, and there are three annular ducts with different heights. Each annular duct is provided with 8 exhaust ports symmetrically distributed, such as Figure 5 shown. The gas discharged from the exhaust port flows to the area near the furnace wall in the furnace body, which avoids the appearance of blank areas in the air distribution. The height of the highest exhaust port is lower than the top of the grate.

[0130] A slender channel is arranged under the grate, and the channel is used to pass ...

Abstract

The invention provides a garbage pyrolysis and incineration device and a working method thereof. The pyrolysis and incineration device comprises a stock bin, a feeding channel, a vertical furnace body, a fire grate and two combustion chambers, and further comprises at least two cavities, a heat storage material, a pipeline, a driving device and a channel, wherein the cavities are formed on the outlet sides of the two combustion chambers; the heat storage material is arranged inside the device or on the side part of the device; the input end of the pipeline is communicated with any one of the at least two cavities, and the output end of the pipeline is communicated with the furnace body; the driving device is used for driving the at least two cavities to move horizontally or rotate, so that when any one of the at least two cavities is communicated with the two combustion chambers, the other cavity is communicated with the input end of the pipeline; the channel is formed below the fire grate; and ash leaking from the fire grate passes downwards through the channel, and air passes upwards through the channel. The garbage pyrolysis and incineration device has the advantages of high garbage treatment capacity, low tar content of pyrolysis gas, high degradability of dioxin due to high incineration temperatures in the two combustion chambers, low running cost, high heat supply and power generation amounts of low-tonnage garbage and the like, and can be widely applied to garbage treatment.

Description

technical field [0001] The invention relates to a pyrolysis incineration device. Background technique [0002] At present, my country's municipal solid waste generally has the characteristics of high moisture content (above 50%) and high ash content (up to about 30%). The pyrolysis incineration device can better adapt to this kind of working condition, and has received more and more attention and popularization and application. [0003] In the traditional vertical converter pyrolysis gasification incineration device, the furnace body is a cylindrical vertical structure installed on a rotary platform. There is a rotating conical grate in the furnace body, and the air passes through the conical grate and enters the Furnace body. This type of vertical converter pyrolysis gasification incinerator has many deficiencies, such as: [0004] 1. The pyrolysis reaction temperature in the pyrolysis furnace is relatively low, and garbage below a certain calorific value will not be sui...
