The present disclosure relates to a degradation device and degradation method, in particular to, a degradation device for processing an organic matter and an organic matter degradation method.
For the current marketed degradation device, such as, a volume reduction device disclosed in TW Patent TWI698292, a reaction chamber is mainly stacked with an organic matter therein, and it slowly and simultaneously performs a drying, carbonization and ashing steps on the organic matter. Since the reaction chamber does not have a chimney that diffuses exhaust gas into the atmosphere, to achieve the drying, carbonization and ashing of the organic matter, an exhaust pipe for removing exhaust gas from a top space of the reaction chamber is disposed, and a post process for processing the exhaust gas is required. In order to keep the steps of drying, carbonization and ashing at the lower end of the organic matter for a long time, a low-oxygen gas supply method is adopted. The gas supply method is for example illustrated by CN Patent CN104456574B, an air supply mechanism is equipped for supplying air to the reaction chamber, wherein the air supply mechanism has a blower to blow air to the main pipe and multiple branch pipes that branch from the main pipe in its length direction and blow air into the reaction chamber.
Regarding the drying, carbonization and ashing at the lower end of the organic matter, TW Patent Application TW200602134 discloses a powdery ceramic layer, a charcoal layer, a sawdust layer and an organic waste layer are stacked on the bottom plate of the reaction chamber in sequence, the charcoal layer is used to pre-heat the powdery ceramic layer to make the powdery ceramic layer store heat and achieve thermal radiation effect. However, the powdery ceramic layer merely stores the heat, and the powdery ceramic layer achieves the thermal radiation effect after storing the heat. As stated by the above TW Patent Application, when the residue is discharged, the powdery ceramic layer must be scraped out, and the thickness of the remaining powdery ceramic layer must be controlled. In other words, when using the reaction chamber next time, it is necessary to consider the layer thickness of the powdery ceramic layer left before, and then re-lay the powdery ceramic layer. Obviously, this causes trouble and inconvenience in operation. For example, it may be time-consuming and wasteful to measure the thickness of the powdery ceramic layer at different positions with a ruler every time, and then the powdery ceramic layer is smoothed back and forth several times with a scraper, and then the powdery ceramic to be added is calculated. After adding the powdery ceramic, the powdery ceramic layer is scraped back and forth repeatedly with a scraper several times to make the heat radiation present a uniform thermal effect on the organic waste layer.
TW Patent Application TW200602134 discloses a heat source that merely from the powdery ceramic layer and the charcoal layer on bottom of the reaction chamber. However, in an actual operation, the thickness of the organic waste layer is much larger than the thicknesses of the ceramic layer and the charcoal layer. The thermal energy for degrading organic waste can only be gradually transferred from the powdery ceramic layer and charcoal layer at the bottom of the reaction chamber to the upper organic waste layer. The person with the ordinary skill in the art knows that the heat transfer effect of organic waste is very poor, so this makes it take a very long time for the technology of TW200602134 to transform the entire organic waste layer into a carbonized layer. Further, in the process, the heat energy transferred from the powdery ceramic layer and charcoal layer to the upper layer will also escape from the wall of the reaction chamber to the outside of the reaction chamber, which in turn makes the heat energy generated by the powdery ceramic layer and the charcoal layer unable to be effectively used and wasted.
