Description

Technical Field

[0001] The utility model relates to the technical field of charcoal preparation, in particular to a charcoal dry distillation device. Background Art

[0002] Charcoal is a product with a relatively large consumption in people's daily life and industrial production. At present, the main carbonization methods for producing charcoal are earth kilns, self-ignition methods, and dry distillation methods. Although earth kilns can ensure the quality of charcoal, the carbonization time is relatively long, the production efficiency is low, generally about 40 days, and a large amount of smoke is generated during carbonization. The harmful gases contained in the tail gas are directly discharged into the atmosphere, seriously polluting the environment and not meeting the environmental protection requirements. Most manufacturers produce kilns using the self-ignition carbonization kiln; the self-ignition method relies on the material itself to generate heat to carbonize itself, which is essentially oxygen-deficient combustion. The disadvantage is that there are dead corners during carbonization and the finished product rate is low. The dry distillation method has a short carbonization time, is smokeless and dust-free, is easy to operate, and the product quality is guaranteed. The carbonization rate is 100%. The carbonized product is not crushed and has a high appearance quality. Therefore, the dry distillation carbonization technology is currently the most suitable carbonization technology for popularization and application. However, the current dry distillation carbonization kiln also has certain deficiencies, mainly including low cooling time and efficiency, direct discharge of combustible gas and wood vinegar liquid without separation, affecting the environment and causing waste of resources, etc. Content of the Utility Model
