Description

Technical Field

[0001] The utility model relates to the technical field of charcoal production, and more specifically to dry distillation carbonization equipment. Background Art

[0002] The dry distillation carbonization furnace is a common equipment in the charcoal production process. The dry distillation carbonization furnace includes a furnace body and a furnace arranged inside the furnace body. The gas generated during the carbonization of charcoal contains three main categories: wood vinegar, wood tar, and combustible gas. The existing dry distillation carbonization furnace is generally an upper exhaust structure. When the combustible gas generated by the internal firewood is needed during the carbonization process of the upper exhaust dry distillation carbonization furnace, the combustible gas generated in the furnace must be transported to the bottom of the furnace body of the dry distillation carbonization furnace through a pipeline for combustion. During the transportation process, the wood vinegar and wood tar in the gas will be deposited in the pipeline, which is easy to cause pipeline blockage, which will cause the internal pressure of the furnace to increase, explode, and cause safety accidents. At the same time, according to the principle of physics that hot air goes up, the upper exhaust leads to a large temperature difference between the upper and lower parts of the furnace of the dry distillation carbonization furnace, and the high-temperature gas inside the furnace of the dry distillation carbonization furnace has a short residence time, low thermal efficiency, and different carbon contents in the carbonized charcoal, resulting in a low carbonization rate. In addition, because a lot of gas delivery pipelines and sealing valves are required, the upper exhaust gas dry distillation carbonization furnace has high manufacturing cost, high use cost, complex operation, and is prone to safety accidents caused by operating errors.

[0003] Therefore, how to provide a dry distillation carbonization equipment that can solve the pipeline blockage problem and ensure production safety is one of the technical problems that urgently need to be solved in this field. Utility Model Content
