NOVELTY - A biomass continuous pyrolysis device comprises drive motor (1), heat pipe (3), feeder (4), feed cooler (5), electric furnace (6), spring feeder (7), speed reducing air outlet (8), carbon box (9) and condensation collecting system. The output shaft of drive motor is connected with spring feeder. The spring feeder is mounted in heat pipe, where spring feeder is divided into front closed spring, medium wide spring and rear reversed spring connected with output shaft of drive motor. The feeder (4) and feed cooler (5) are sequentially arranged on heat pipe corresponding to closed spring.    USE - Biomass continuous pyrolysis device.    ADVANTAGE - The reaction temperature is mesotherm. The reaction pressured is close to normal pressure, where reaction time is short, and quality of product is stable.    DETAILED DESCRIPTION - Biomass continuous pyrolysis device comprises drive motor, heat pipe (3), feeder, feed cooler, electric furnace (6), spring feeder (7), speed reducing air outlet (8), carbon box (9) and condensation collecting system. The output shaft of drive motor is connected with spring feeder. The spring feeder is mounted in heat pipe, where spring feeder is divided into 3 parts, sequentially comprising front closed spring, medium wide spring and rear reversed spring from one end connected with output shaft of drive motor. The feeder and feed cooler are sequentially arranged on heat pipe corresponding to closed spring. The electric furnace is arranged on heat pipe corresponding to wide spring. The carbon box is arranged on heat pipe corresponding to connecting part of wide and reversed springs. The speed reducing air outlet is arranged on heat pipe corresponding to reversed spring. The speed reducing air outlet is communicated with condensation collecting system.
