NOVELTY - Inner and outer combined heating-type biomass pyrolysis device comprises a pyrolysis system (1), a primary separation system (2), a condensing separation system (3), a non-condensable gas collecting and measuring system (4), a gas recycling system (5), a carrier gas supply system and a control system. A reaction tube is installed outside the pyrolysis furnace. The inner part of the reacting pipe is installed with a thermoelectric couple. The lower end of the reaction tube is connected to carrier gas supply system, while the upper end is connected to primary separating system.    USE - Used as an inner and outer combined heating-type biomass pyrolysis device.    DETAILED DESCRIPTION - Inner and outer combined heating-type biomass pyrolysis device comprises a pyrolysis system (1), a primary separation system (2), a condensing separation system (3), a non-condensable gas collecting and measuring system (4), a gas recycling system (5), a carrier gas supply system and a control system. A reaction tube is installed outside the pyrolysis furnace. The inner part of the reacting pipe is installed with a thermoelectric couple. The lower end of the reaction tube is connected to carrier gas supply system, while the upper end is connected to primary separating system. The condensing separation system is connected to the back end of primary separating system. The non-condensable gas collecting and measuring system is connected on the condensing separation system. The non-condensable gas collecting and measuring system is connected to a fuel gas collecting recycling system. The pyrolysis system is used for provide heat while heating. The control system controls heat in a carbonization device.
