NOVELTY - Biomass spiral pyrolysis reactor with drying function comprises a cylinder, a first speed regulating motor and a spiral feeder. The cylinder is located at the inlet of the spiral feeder. The spiral feeder discharging port is connected to the lower part of a vertical drying upgrade cylinder. The lower part of a vertical drying upgrade cylinder connected to an induced draft fan outlet. The upper part of the vertical drying upgrade cylinder is connected to a cyclone separator inlet. The discharging port of the cyclone separator is connected to the feeding port of the spiral pyrolysis reactor.    USE - The reactor is useful for achieving pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization of biomass.    ADVANTAGE - The reactor can dry the biomass material using the high temperature smoke gas generated by heating it.    DETAILED DESCRIPTION - Biomass spiral pyrolysis reactor with drying function comprises a cylinder, a first speed regulating motor and a spiral feeder. The cylinder is located at the inlet of the spiral feeder. A discharging port of the spiral feeder is connected to one side of the lower part of a vertical drying upgrade cylinder. The lower part of the vertical drying upgrade cylinder is connected to an induced draft fan outlet. The upper part of the vertical drying upgrade cylinder is connected to a cyclone separator inlet. The discharging port of the cyclone separator is connected to the feeding port of the spiral pyrolysis reactor and the cyclone separator is located at the upper part of the spiral pyrolysis reactor. The other end of the spiral pyrolysis reactor is respectively provided with a lower and an upper outlet. The lower outlet is a pyrolytic carbon outlet and the upper outlet is thermal gas outlet. The middle part of the spiral pyrolysis reactor is located in a combustion heating chamber. The spiral pyrolysis reactor input is connected to a second speed regulating motor. The upper end of the combustion heating chamber is provided with a smoke gas outlet and the smoke gas outlet is connected to induce draft fan inlet via pipeline. The vertical drying upgrade cylinder and the cyclone separator forms an air flow type dryer. The spiral pyrolysis reactor has single screw propelling mechanism or double screw propelling mechanism or triple screw propelling mechanism.    DESCRIPTION OF DRAWING(S) - The drawing illustrates a schematic representation of the biomass spiral pyrolysis reactor.
