Instead, the layout angle by adjusting 3021 blade of scraper plate can be realized, as shown in Figure 3 and Figure 4.) flammable solid is pushed to discard
Composition granule 4 is moved to the center of big disk 303, and big disk 303 is hollow disc structure, flammable solid discard composition granule 4 from
Fall, fallen on the roundel 304 of its lower end in the hollow round hole of big disk 303, flammable solid discard composition granule 4 from
It is moved under the action of mental and physical efforts to the direction far from roundel 304, reaches the edge of roundel 304, flammable solid discards composition granule 4
It falls, is fallen on the big disk 303 of the lower section of roundel 304 from roundel 304, flammable solid discards composition granule 4 from upper
Become during falling down by the effect of big disk 303 and roundel 304, running orbit of the mud granule 4 in cracking zone
It is long, the pyrolysis time that flammable solid discards composition granule 4 is increased, makes the cracking that flammable solid discards composition granule more thorough.It can
Combustion solid waste 4 heat source in cracking zone of composition granule comes from the high-temperature gasification combustible gas of gasification zone generation, what gasification zone generated
There are many act on for combustible gas：1) pyrolysis zone is transported to from gasification zone, the heat source as pyrolysis zone uses；2) side take-off of flue gas
Heat source of the branch also as preheater 307 to heat cold wind, becomes hot wind into the cold wind of gasification section in this way, and hot wind enters
Gasification section, the heat loss than directly cold wind being used to enter gasification section is few, because the temperature difference of hot wind and gasification section is small, cold wind and gasification
The temperature difference of section is big, if directly entering gasification section using cold wind, entropy loss when cold wind meets with gas in gasification section is big, uses
Hot wind enters gasification section, and entropy loss when hot wind meets with gas in gasification section is big；Still further aspect is directly entered using hot wind
Gasification section, range of temperature is smaller in gasification section, control gasification section easy to operation.
