Danger, keeps the content of the carbon monoxide and nitrogen oxides in exhaust gas almost nil, while improving garbage treatment efficiency.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
As shown in Figure 1, a kind of house refuse self-pyrolysis processing unit, includes the furnace body 100 for incineration firing；
Centrifugal blower 200 for sucking flue gas and air；
Flue gas for sucking centrifugal blower 200 and the pipeline 300 in air delivery to furnace body 100；
The furnace body 100 be distributed as from bottom to up stack layer 110, burning zone 120, baking zone 130, into 140 and of the bed of material
Go out smoke stratification 150, the top that the furnace body 100 is located at smoke stratification 150 is equipped with outlet flue, and the furnace body 100 is located at into the bed of material
140 side wall is equipped with feed inlet, and centrifugal blower 200 is arranged at the outlet flue of furnace body 100, and centrifugal blower 200 passes through pipeline 300
It is connected to furnace body 100, for stack layer for accumulating incineration firing, burning zone refers to the heating one end part for incineration firing, dries
Dried layer becomes drying under the action of burning zone burns, and is convenient for flue gas secondary combustion, launches and feeds for rubbish into the bed of material.
The side wall that the furnace body 100 is located at burning zone 120 is equipped with opening, described 300 one end of pipeline and burning zone 120
Open communication.
The furnace body 100 is located at into being equipped with sealing cover (not shown) at the feed inlet of the bed of material 140.
A kind of processing method of house refuse self-pyrolysis, this approach includes the following steps：
Step 1：Rubbish is poured into from the feed inlet of furnace body, closes sealing cover；
