However, in this process, with the resistance loss of the pyrolysis gas in the furnace, when the pyrolysis gas used for cyclic heating reaches the bottom of the furnace at the end far away from the gas outlet, the gas flow rate and air pressure will drop to varying degrees, resulting in The power of the gas passing through the material plate is reduced, and the heat supplied to the material on the bottom of the furnace is inconsistent, so that the pyrolysis of the raw material on the bottom of the furnace is uneven

The present invention discloses a rotation bed dry distillation furnace, which comprises: a furnace body , wherein a hearth is limited in the furnace body, and the furnace body is provided with a material inlet and a material outlet; a material filling plate, wherein the material filling plate is horizontally arranged inside the hearth so as to separate the hearth into the hearth space and the overhead space positioned below the hearth space; a circulation device, wherein the circulation device and the furnace body are adjacently arranged so as to make pyrolysis gas in the hearth circularly flow between the hearth space and the overhead space; and at least a gas distribution structure, wherein the gas distribution structure is obliquely arranged below the material filling plate, the gas distribution structure and the horizontal plane of the material filling plate form an included angle of 30-60 DEG, and the gas distribution structure is provided for uniformly pyrolyzing the material on the material filling plate. According to the rotation bed dry distillation furnace, the gas distribution structure is arranged to make the pyrolysis gas uniformly pass through the material layer in the hearth under the effect of the circulation device, such that the material distributed on the material filling plate is uniformly pyrolyzed so as to obtain the product with the uniform quality.
Description
technical field [0001] The invention relates to the field of industrial technology, in particular to a rotary bed carbonization furnace. Background technique [0002] The rotary bed is used as the pyrolysis technology of the dry distillation furnace, and the pyrolysis gas is forced to circulate in the furnace to improve the heat transfer of the materials in the furnace, so as to increase the output of the pyrolysis material in the rotary bed. The bottom of the traditional rotary bed furnace is a flat structure. The forced circulation of pyrolysis gas enters the furnace from the inlet passage on one side of the furnace bottom, and is led out by the circulation fan from the gas outlet on the upper part of the material, thus realizing the forced convection of pyrolysis gas. However, in this process, with the resistance loss of the pyrolysis gas in the furnace, when the pyrolysis gas used for cyclic heating reaches the bottom of the furnace at the end far away from the gas outle...
