In the utility model, a combustion room is followed successively by dry section, pyrolytic gasification area, combustion zone and burnt zone from top to bottom. High temperature pyrolysis of the rubbish first in dry section by the heat radiation of microwave thermal energy and dry section wall, pyrolytic gasification area and combustion zone Gasification smoke convection and the lower realization of pyrolytic gasification heat transduction four directions effect are dry so that the moisture in rubbish quickly volatilizees.

Dried rubbish resolves into the combustibles such as carbon monoxide, gaseous hydrocarbons in pyrolytic gasification area and enters mixed flue gas In.Residue after pyrolytic gasification（The inorganic dirt and inert material that tar liquid, purer carbon and rubbish contain in itself Matter）Fully burn into combustion zone.Combustion zone can be divided into zoneofoxidation and reducing zone in short transverse, and reducing zone is located in zoneofoxidation Violent oxidation reaction occurs for face, interior carbon, tar and the oxygen of occurring of zoneofoxidation, and ignition temperature can reach 850-1000 DEG C, burning The heat of generation is used for providing the heat needed for reducing zone, pyrolytic gasification area and dry section；Interior CO in reducing zone₂And H₂O is red-hot C reduction, produce CO, H₂Deng fuel gas, into mixed flue gas.The utility model can mutually collect with the waste gas system of rear end Into can help mixed flue gas introducing dual firing chamber each area's thorax by the air-introduced machine of rear end waste gas cleaning system.

The residue that combustion zone produces by dump grate mechanical presses, it is broken after row burn away to burnt zone, treat it After completely burned and cooling, discharged out of the furnace by helical slag removing machine.The mixed flue gas that a combustion room produces at the same time enters dual firing chamber and first High-temp combustion is carried out in Hou Ge areas thorax.Part water vapour, low boiling point fuel gas from dry section, pyrolytic gasification area and The First air introduced by burnt zone by First air intake and a main feed pipe（Combustion-supporting oxygen）Combustion zone is sent into carry out Mixed combustion, produces substantial amounts of thermal energy, and the water vapour that dry section produces can be as the partial gasification agent in pyrolytic gasification area.It is vertical The type of furnace and unique air supply mode meet the temperature and reaction air capacity that rubbish needs in the crucial pyrolytic gasification stage（Oxygen deprivation And anaerobic）Condition, and the rubbish that can react participation maintains time enough in this environment.

It can thus be seen that rubbish realizes the two-stage distribution of energy after pyrolysis in pyrolytic gasification area, pyrolysis produces Mixed flue gas burn into dual firing chamber, the residue after pyrolysis burns away in the combustion zone of pyrolysis gasification furnace, the heat of rubbish Decompose, gasify, the dynamic equilibrium formd along direction is moved downward of burning, it is outer with dreg removing system continuous and steady operation feeding intake Under the conditions of portion, the physical and chemical process of each reaction section also continuously and stably carries out in stove, therefore pyrolysis gasification furnace can connect Continuous ground, normally operate.

It is a richness since traditional grate furnace directly burns（By force）Oxidizing process, can produce in burning process substantial amounts of SO₂, HCl and NOx, meanwhile, because fire grate can not bear 1000 DEG C or so of high temperature for a long time, limited the operating temperature of burning System, and less than 1000 DEG C of incineration temperature is difficult to make dioxin fully and completely decompose.The core of thermal decomposition gasification combustion technology is exactly The generation of bioxin is can inhibit, while the harmful substances such as bioxin, major embodiment are catalytically decomposed completely using the high temperature of dual firing chamber At following two aspects：

First, in dual firing chamber, swirl flow air can be provided per area's thorax, the oxygen in flue gas is supplemented, makes to be pyrolyzed The combustible gas that journey produces fully burns under the oxygen-enriched of dual firing chamber, hot conditions, and the temperature of burning reaches 900 ~ 1200 DEG C, flue gas Dual firing chamber residence time more than 2.0s, can decompose the completely burneds such as polychlorinated biphenyl material, carbon residue, remain dioxin Amount is few, thoroughly decomposes the oxious component in flue gas；

Second, decomposed polychlorinated biphenyl material is having CuCl₂, C atoms catalysis under conditions of, in 250-300 DEG C of phase Between can synthesize dioxin once again, but indoor in a combustion, for temperature control at 850 DEG C to 1000 DEG C, it is in reducing atmosphere to control to oxygen amount （Anoxic or combustion with meagre oxygen state）, copper, aluminium, iron will not aoxidize, and the generation such as no CuO there will not be CuCl₂Generation and presence, Also the catalyst for just not making dioxin synthesize again（CuO、CuC1₂Etc. compound）, without CuCl₂With the catalysis of carbon atom, two The synthesis of English is disliked also just without possible.Pyrolytic gasification technology can also reduce NOx and SO at the same time₂Discharge, this is because one combustion Room anoxycausis category reducing atmosphere, N, S are seldom aoxidized and are left in slag.And unique dual firing chamber's design ensures flue gas The oxygen formed in turbulent flow, with air is sufficiently mixed, and required air excess degree is low, correspondingly reduces the N sources from air, So that NOx discharges reduce.In addition, after pyrolytic gasification reaction, the chlorine element overwhelming majority contained in rubbish is transferred to solid phase production Thing（Bottom ash）In so that HCl contents are far below the standard limited value of conventional domestic waste incineration in smoke evacuation.

It is emphasized that to reach above-mentioned both sides environmental-protecting performance and realize the innoxious of rubbish, minimizing processing, One combustion is indoor dry, is pyrolyzed, burning, burn all allow for smoothly realizing treatment process and handle engineering be effectively connected and Continuous operation.And dry section micro-wave drying and furnace body science structure design be its treatment process, processing engineering have Imitate the basis of trouble-free operation.
