DETAILED DESCRIPTION - A biomass gas high-temperature anaerobic dry-distillation pyrolyzing device comprises a feed hopper (1), a raw material conveyor (2), a discharging groove (3), a supporting frame (4), a biomass pyrolyzing converter (5), a charcoal outlet pipe, a thick gas outlet pipe, a first blast pipe, a second blast pipe, a charcoal conveyor (8), a cooling water pipe, a cooling tower (11), a filtering tower (12), a purifying tower (13), a liquid slurry tower, and gas transporting pipes. The feed hopper is installed on upper side end of one end of raw material conveyor. A rotating shaft with spiral piece is installed on axis line of raw material conveyor. The supporting frame is installed between the raw material conveyor and the biomass pyrolyzing converter. The discharging groove is located on end of raw material conveyor and biomass pyrolyzing converter and opposite to discharging hopper of raw material conveyor and feed hopper of biomass pyrolyzing converter. A spiral transporting piece is assembled on rotating axis driven by an electromotor on the biomass pyrolyzing converter. Left heating furnace ports and right heating furnace ports are installed on a heating device installed on lower side of biomass pyrolyzing converter. The first blast pipe is connected with a blast blower and is communicated with the left heating furnace ports. The second blast pipe is connected with the blast blower and is communicated with the right heating furnace ports. Lower side end outlet port of the biomass pyrolyzing converter is opposite to the charcoal outlet pipe. Charcoal inlet port of charcoal conveyor is communicated with charcoal outlet pipe, where a spiral piece is installed on rotating axis driven by electromotor located on the charcoal conveyor. The thick gas outlet pipe is installed on side end of the biomass pyrolyzing converter and is communicated with one end of the thick gas transporting pipe. Another end of the thick gas transporting pipe is communicated with lower end cavity of the cooling tower. The cooling water pipe is spread to inner side of the cooling tower through the upper side wall of the cooling tower. Spraying nozzles are installed on the cooling water pipe of the cavity of the cooling tower. Filtering layers are distributed on the cavity of the cooling tower. A first valve gate is installed on lower end of the cooling tower. Top end cavity of the cooling tower is communicated with lower end cavity of filtering tower by a first gas transporting pipe. A baffle plate is installed on center of cavity of the filtering tower. Upper filtering layer and lower filtering layer are distributed in the cavity of the filtering tower located on upper and lower parts of the baffle plate. A second gate valve is installed on lower end of the filtering tower. A second gas transporting pip for communicating the baffle plate of the cavity of the filtering tower with the lower filtering layer is spread in the cavity of the lower end of the purifying tower. Purifying filtering layers are distributed in the cavity of the purifying tower. A third gate valve is installed on lower end of the purifying tower. A third gas transporting pipe is communicated with top end cavity of the purifying tower and is communicated with lower end cavity of the liquid slurry tower through lower side wall of the purifying tower. Slurry filtering layers are distributed in cavity of the liquid slurry tower. A fourth gate valve is installed on lower end of liquid slurry tower. Two ends of fourth gas transporting pipe are respectively communicated with upper end cavity of liquid slurry tower and third gas transporting pipe. Two ends of a fifth gas transporting pipe with switches are respectively communicated with upper end cavity of liquid slurry tower and middle cavity of the filtering tower. A sixth gas transporting pipe with switches is installed on top end of the filtering tower.
