NOVELTY - Continuous rotary biomass pyrolyzing carbonizing and boiler heating integrated device comprises raw material transmitting device, rotary drying furnace, and rotary carbonizing furnace. The rotary drying furnace comprises a drying furnace cylinder body and shoveling plates provided on the drying furnace cylinder, where breathing holes are formed on the shoveling plates. A baffle is provided between two adjacent shoveling plates and connected with the cylinder body. The rotary carbonizing furnace comprises furnace hearth and rotary furnace.    USE - Continuous rotary biomass pyrolyzing carbonizing and boiler heating integrated device.    ADVANTAGE - The device improves the efficiency of rotary carbonizing furnace.    DETAILED DESCRIPTION - Continuous rotary biomass pyrolyzing carbonizing and boiler heating integrated device comprises raw material transmitting device, rotary drying furnace, and rotary carbonizing furnace. The raw material transmitting device is connected with the rotary drying furnace, which is connected with the rotary carbonizing furnace via a star-shaped blanking device. The carbonizing material formed in the pyrolyzing and carbonizing process in the rotary carbonizing furnace is discharged via a carbonizing material discharging hole. The rotary drying furnace comprises a drying furnace cylinder body and shoveling plates provided on the drying furnace cylinder, where breathing holes are formed on the shoveling plates. A baffle is provided between two adjacent shoveling plates and connected with the cylinder body. The rotary carbonizing furnace comprises furnace hearth and a rotary furnace, in which one path of high-temperature hot gas generated by the combustion in oxygen configuring combustion chamber is fed in the carbonizing section in the furnace hearth of the rotary carbonizing furnace. The rotary furnace comprises a cylinder body, an internal heat pipe, and a stopping ring, where one end of the internal heat pipe is fixed on one side wall of the cylinder body and fixed on the wall of cylinder at another side via the stopping ring. Parts of high-temperature hot gas generated in the oxygen configuring combustion chamber enter through one end of the internal heat pipe via the furnace hearth, an afterheat transmitting pipe from another end of the internal heat pipe, and finally the rotary drying furnace via a draught fan. Another path of the high-temperature hot gas from the oxygen configuring combustion chamber is fed in the biomass boiler from another one smoke channel.
