The invention discloses an internal and external dynamic heating
solid organic matter pyrolysis combination device in double-column mixing process. The device comprises a plurality of
pyrolysis chambers and heating chambers, wherein each heating chamber is internally provided with a one-process
flue and a multi-process
flue capable of forming a fold-back heating passage, and heating gas in each two adjacent heating chambers flow reversely; each
pyrolysis chamber is internally provided with two columns of agitators, and each column of
agitator is provided with a single-process heating agitatorand a multi-process heating
agitator which are connected in parallel with each other, the multi-process heating agitators can form a fold-back stirring / heating passage through a communicating pipeline, and heating gas in the two columns of agitators flow reversely; the agitators are driven to rotate through external power; a feeding device and a pyrolysis gas
output device are arranged at the topof each pyrolysis chamber, and a discharging device is arranged at the bottom of each pyrolysis chamber. The internal and external dynamic heating
solid organic matter pyrolysis combination device enlarges the heating area, reduces the
thermal resistance, ensures uniform heating and
high heat transfer efficiency, and increases the gas permeability. The pyrolysis chambers can be copied and combined, and are suitable for large-scale industrial production. The internal and external dynamic heating
solid organic matter pyrolysis combination device provides strong protection for material pyrolysis,is high in operation adaptability and productivity, and has efficacies of
environmental protection,
energy conservation and safety.
