DETAILED DESCRIPTION - Agriculture and forest biomass continuous pyrolysis and product segment collecting and purifying device comprises a hopper, a pyrolytic pipe, a carbon box, a one-level condensation collector and a two-level condensation collector. A discharge port of a lifter is located on the upper part of the hopper. A discharger is located on the lower part of the hopper. A storage bin is located on the lower part of the discharger. The pyrolytic pipe is located on the lower part of a material storage bin. A spiral feeder and a spring conveyor are located in the pyrolytic pipe. The spiral feeder is located on the lower part of the material storage bin. One end of the spiral feeder is connected to a driving motor set on the outer side of the pyrolytic pipe, while the other end is connected to one end of the spring conveyor. The other end of the spring conveyor is a free end. The pyrolytic pipe passes through a combustion furnace, and is connected to the carbon box. A pyrolysis gas outlet is located on the upper part of the carbon box. The pyrolysis gas outlet comprises the one-level and two-level condensation collectors, a spraying purifier, a partition board dehydrator, a filler purifier and a roots blower which are orderly connected by a pipeline. An outlet of the roots blower is connected to the combustion furnace and a gas collector by a two-way valve. A smoke discharge port is located on the upper part of the combustion furnace, and is connected to a drier. An INDEPENDENT CLAIM is also included for agriculture and forest biomass continuous pyrolysis and product segment collecting and purifying method, comprising (i) placing the biomass raw material in the hopper by the lifter, discharging, and orderly conveying to the spiral feeder and the spring conveyor by the pyrolytic pipe having the same opening to the storage bin, finishing pyrolysis, and carrying out carbonization in a continuous moving process to obtain the pyrolysis product; and (ii) placing the pyrolysis product in the carbon box by the pyrolytic pipe, depositing the pyrolytic semi coke in the pyrolysis product placed at the bottom of the carbon box, discharging the pyrolytic volatile matter in the pyrolysis product from the pyrolysis gas outlet set on the upper part of the carbon box with the roots blower, orderly passing through the one-level condensation collector and the two-level condensation collector which are having the same opening, and collecting to obtain a separated tar and pyroligneous liquor product, processing the non condensed gas product by the spraying purifier, partition board dehydrator and filler purifier to obtain a clean pyrolysis gas, then extracting the pyrolysis gas by the roots blower, passing one part of the pyrolysis gas to the combustion furnace for burn-back to provide the heat source for pyrolysis reaction, and collecting the remaining pyrolysis gas, and discharging the gas from the combustion furnace to the drier from the smoke discharge port set on the upper part of the combustion furnace.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the continuous pyrolysis and product collecting purifying device.
