USE - Used as biomass pyrolysis carbon gas oil cogeneration system.    ADVANTAGE - The system has good control of process parameters and pyrolysis effect.    DETAILED DESCRIPTION - Biomass pyrolysis carbon gas oil cogeneration system comprises a transporting belt machine (1), a spiral discharging machine (6), a cyclone separator I (7) and a gas storage cabinet (12). The system further comprises a rotary baking furnace (2), a straight pyrolysis furnace, an air cooling tower, a water cooling tower, a washing tower and a purification tower. The straight pyrolysis furnace from top to bottom is sequentially set with a preheating zone, a pyrolysis reaction zone, a buffer zone and a water cooling zone. The outlet of the transporting belt machine is connected with inlet of the rotary baking furnace. The outlet of the rotary baking furnace is connected to the inlet at the top of the straight-pyrolysis furnace. The lower end of the discharge port of the straight-pyrolysis furnace is connected with the inlet of the spiral discharging machine. The upper part pyrolysis gas export of the straight-pyrolysis furnace is connected to inlet of the cyclone separator I. The outlet of the cyclone separator I is connected with lower part inlet port of the air cooling tower. The upper part outlet of the air cooling tower is connected with the lower part inlet port of the water-cooling tower. The upper part outlet of cooling tower is connected with the inlet port of the washing tower. The upper portion air outlet of the washing tower is connected with lower portion air inlet of the purification tower. The upper part air outlet of the purification tower is connected to air inlet of the storage tank. The cyclone separator I, the air cooling tower, the water- cooling tower and the washing tower are provided below the water sealing tank. The cyclone separator I, the air cooling tower, the water cooling tower and the washing tower outlet is respectively connected to the inlet of the water sealing tank.
