High-temperature flue gas is passed through the bed of pyrolysis gasifying device (1) and catalytic reforming unit (3) by S2, heats the solid-state in bed
Bed material；First regulating valve (7) and the second regulating valve (8) adjust enter pyrolysis gasifying device respectively according to the difference of preset temperature
(1) and the flue gas flow of catalytic reforming unit (3) bed；
Organic solid fuel is passed through by S3 after pyrolysis gasifying device (1) and catalytic reforming unit (3) reach preset temperature
To pyrolysis gasifying device (1), gasifying agent is passed through pyrolysis gasifying device (1)；Pyrolysis or gasification reaction occur for organic solid fuel,
Evolution pyrolysis gas simultaneously generates coke；
The step S3 coke generated is passed through in incinerator (2), the gasification reaction of coke is carried out, for generating High Temperature Gas by S4
Body；The gas mixing that the pyrolysis gas and incinerator (2) coke gasification that step S3 is generated generate forms mixed gas, described mixed
Catalytic reforming unit (3) are passed through after closing gas；
S5, catalytic reforming unit (3) are provided with catalyst (9)；The mixed gas is contacted with catalyst (9), and catalysis weight occurs
Whole reaction generates high-temperature gas；
S6, the high-temperature gas are passed through condensing unit (4), and pyrolysis oil after cooling is collected by collection device (5), can not
Condensing gas is discharged by product exit.
