| Popis: | This research tried resource recovery of the waste wood and effective utilization. In our study, we used walnut as waste wood. We distillated walnut in dry distillation boiler, changed walnut charcoal. Then, we recovered heat energy that is generated in the time, and attempted the effective utilization of energy. And, we utilized the property of the charcoal of the porous body, produced walnut charcoal as an inner-wall breathing material, and tired the improvement in the indoor environment. The conclusion were as follows; 1)If we distilled walnut, we produce walnut charcoal, which is 28% of the walnut's mass in simple distillate experiment. 2)If we distilled walnut, we produce walnut charcoal, which is 15% of the walnut's mass in dry distillation boiler. 3)The heat recovery rate of dry distillation boiler is 17%. The heat recovery of walnut produce 5.26 [MJ/kg], which is 12% of the quantity of heat of walnut. 4)Inner-wall breathing material of walnut charcoal have dehumidification and spout moisture effect. 5)Inner-wall breathing material of walnut char-coal cut indoor overall heat transfer coefficient for 55%. 6)Inner-wall breathing material of walnutcharcoal has aerial purification performance by the residual wood vinegar component in the inside the walnut charcoals. |
