Embodiment 1
[0044] First, by adjusting the temperature of the hot flue gas generated by the combustion device and the air distribution plate in the flue 5, the temperature of the reaction chambers at all levels is maintained at 500°C; The rotating speed of each is maintained at 7.5 r / min, and the included angle between the rotating stirring blade 43 and the tangential direction of the circumference of the stirring frame 42 is maintained at 15°. Using a belt conveyor as the feeding device, the municipal solid waste is continuously fed into the reactor at a feeding rate of 1 t / h, and is continuously thermally decomposed in the reaction chambers of each level until it is completely pyrolyzed in the fourth reaction chamber The generated pyrolysis gas is sent to the combustion device for combustion after a certain amount of dehydration, and is used for the heating of the reactor itself; finally, the remaining waste residue and residual carbon are discharged through the discharge port 6 and coll...
Embodiment 2
[0046] First, by adjusting the temperature of the hot flue gas generated by the combustion device and the air distribution plate in the flue 5, the temperature of the first two-stage reaction chamber is maintained at 430°C, and the temperature of the latter two-stage reaction chamber is maintained at 460°C; then the drive motor is adjusted , the rotating speed of the cage stirrer 4 in the reaction chambers at all levels is maintained at 10 r / min, and the angle between the rotating stirring blade 43 and the tangential direction of the stirring frame 42 is maintained at 20°; The waste plastic is continuously fed into the reactor at a feed rate of 0.6 t / h, and is continuously decomposed by heat in the reaction chambers of each level until the pyrolysis is complete in the fourth-level reaction chamber; the generated pyrolysis gas is condensed After the liquid phase product is separated, the non-condensable gas is connected to another 600°C catalytic reactor for the production of hy...
Embodiment 3
[0048] First, by adjusting the temperature of the hot flue gas generated by the combustion device and the air distribution plate in the flue 5, the temperature of the first three reaction chambers is maintained at 600 ° C, while the temperature of the fourth reaction chamber is maintained at 300 ° C; Drive the motor so that the rotating speed of the cage stirrer 4 in the reaction chambers at all levels is maintained at 15 r / min, and the angle between the rotating stirring blade 43 and the tangential direction of the stirring frame 42 is maintained at 15°; use a screw feeder As a feeding device, the straw raw material is simply crushed at a feeding rate of 0.2 t / h, and then continuously fed into the reactor, where it is continuously thermally decomposed in the reaction chambers of each level until it is completely pyrolyzed in the fourth reaction chamber; After the pyrolysis gas is condensed, the gas phase and liquid phase products are separated, and the remaining coke is discha...
