Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in detail：
Example is as shown in figure 1, a kind of pyrolytic reaction device, including pyrolytic reaction device case 6, is arranged on pyrolytic reaction dress
Material inlet pipe 1 and the oil gas vent 3 at 6 top of housing is put, the semicoke discharge nozzle 7 of 6 bottom of pyrolytic reaction device case is arranged on, if
The distribution device 2 in 1 bottom of material inlet pipe is put, one or more accumulation of heat radiant tube being arranged in pyrolytic reaction device case 6
4, accumulation of heat radiant tube 4 passes vertically through pyrolytic reaction device case 6, and 4 border of accumulation of heat radiant tube is provided with multiple heat transfer fins 5, increases
Plus swept area, simultaneously work as disperseing the effect of falling material.
Used as preferred embodiment of the present utility model, there is necking cone section the pyrolytic reaction device case lower end.
Operation principle of the present utility model is：Coal feeds pyrolytic reaction device from material inlet pipe 1, enters through being arranged in material
Coal is disperseed by the distribution device 2 of 1 lower section of pipe so that in cavity of the coal between pyrolytic reaction device case 6 and accumulation of heat radiant tube 4
Fall.Heat carrier is passed through from accumulation of heat radiant tube 4, and heat transfer heats, to tube wall, then through radiant heat transfer, the coal of whereabouts.Coal is received
Heat pyrolysis, the oil gas adverse current of generation discharge pyrolytic reaction device by oil gas vent 3 upwards, fall pyrolytic reaction under the semicoke of generation
Section is bored in device bottom, then discharges pyrolytic reaction device from semicoke discharge nozzle 7 after being slowly pyrolyzed.
