[0015] Further description will be given below in conjunction with the examples.
[0016] like figure 1 and figure 2 As shown, an external heating type biomass pyrolysis device 10, its main body is a pyrolysis furnace composed of three concentric steel cylinders, from the inside to the outside are the pyrolysis chamber 4, the combustion chamber 2 and the ash discharge channel 8. The innermost pyrolysis chamber 4 is used for the pyrolysis of biomass A to generate gas E, and includes a cylinder bottom 43 connected to the pyrolysis outer wall 45 and an open cylinder mouth 44. The pyrolysis outer wall 45 is provided with a biomass inlet pipe 12, The biomass inlet pipe protrudes from the outer wall 81 of the ash discharge channel, and the pyrolysis chamber 4 is provided with a spiral elevator 3, so that the biomass A is continuously lifted while pyrolyzing in the pyrolysis chamber. The spiral elevator 3 is arranged on the top of the pyrolysis furnace The motor 5 outside the cov...

The invention relates to an external heating biomass pyrolyzing device, consisting of three layers of concentric steel cylinders. A pyrolyzing chamber, a combustion chamber and an ash discharge channel are sequentially arranged from inside to outside. The pyrolyzing chamber is cylindrical and consists of an outer wall of the pyrolyzing chamber, a cylinder bottom and an opened cylinder opening. A biomass inlet pipe is arranged on the outer wall of the pyrolyzing chamber and extends outside the outer wall of the ash discharge channel. A spiral lifter driven by a motor is arranged in the pyrolyzing chamber for lifting materials. The motor is arranged outside a pyrolyzing furnace. The combustion chamber surrounds the outer wall of the pyrolyzing chamber and is provided with a sealed top part and a sealed bottom part. An igniting device is arranged in the combustion chamber. A combustion smoke outlet is arranged at the upper part of the outer wall of the combustion chamber. A fuel inlet pipe is arranged at the lower part of the outer wall of the combustion chamber. The combustion smoke outlet and the fuel inlet pipe extend out of the outer wall of the ash discharge channel. The outmost layer is provided with the ash discharge channel and consists of a top cover, an outer wall of the ash discharge channel and a funnel-shaped ash discharge chamber at the bottom. The top cover is provided with an outlet of pyrolyzing product smoke. The pyrolyzing ash generated in the pyrolyzing chamber is discharged to the ash discharge channel.
Description
technical field [0001] The invention relates to an external heating biomass pyrolysis device, more precisely, it performs anaerobic or oxygen-poor pyrolysis on biomass under high temperature conditions to generate combustible gas, and realizes the reduction treatment of waste biomass resources and resource utilization. technical background [0002] my country's fossil energy structure is dominated by coal, supplemented by oil and natural gas, which is caused by the different reserves of various fossil energy. During the use of fossil energy, a large amount of carbon dioxide, sulfur dioxide and other gases will be produced, resulting in acid rain and the greenhouse effect, thereby polluting the environment. Therefore, actively utilizing existing waste resources to develop new energy sources, changing my country's current energy consumption structure, making effective use of resources while developing clean energy, realizing effective energy substitution and simultaneously so...
