Embodiment example 1
[0030] Such as Figure 2-3 As shown, a pyrolysis carbonization equipment for processing agricultural waste and household waste, including a feed hopper 1, a drying chamber 4, a carbonization chamber 11, a central combustion chamber 34, a dispersed combustion chamber 14, a steam boiler 29, and a coke storage bin 22 , Intake pipeline 16, discharge device 17, discharge auger 18, agitator 31, ventilation furnace wall 35, flue gas pipeline 36, and reservoir 42.
[0031]The combustion chamber comprises a dispersed combustion chamber 14 and a central combustion chamber 34. A carbonization chamber 11 is arranged between the inner wall of the dispersion combustion chamber 14 and the outer wall of the central combustion chamber 34. The side wall of the carbonization chamber 11 is a ventilation furnace wall 35. The walls are vent walls.
[0032] The top of the drying chamber 4 is connected to the feeding funnel 1 through the feed valve 2, the top of the drying chamber 4 is provided with...
Embodiment example 2
[0100] The raw material for pyrolysis is crop straw, and the natural bulk density is 80kg / m 3 , carbonized coke density is 0.4g / cm 3 , the water content is 5%, the drying chamber can accommodate 176kg straw, the drying time is 5min, the carbonization chamber can accommodate 176kg straw, the coke yield is 35%, the pyrolysis cycle is 1.5h, the char yield rate is 41.1kg / h, and the output Every time the auger rotates once, the mass of coke conveyed is 314g, and the discharge time is about 5 minutes.
