Vertical short internal heating fine coal dry distillation oil extraction carbonization furnace

The utility model relates to a novel carbonization furnace, in particular to a vertical short internal heating fine coal dry distillation oil extraction carbonization furnace. An upper-layer combustion chamber and a lower-layer combustion chamber are respectively arranged below a blanking port. The blanking port is 3m+/-0.1 in length and 22cm+/-0.1 in width. A negative pressure cavity is 3m+/-0.1 in length, 93cm+/-0.5 in width and 1m-1.1m in height. The combustion chambers are triangular and are 3m+/-0.1 in length, 57cm+/-0.5 in height and 58cm+/-0.5 in width of a bottom side. The carbonization furnace can conduct carbonization dry distillation for fine coal with granule size smaller than 6mm and can fully extract side products such as coal tar from the fine coal. Produced dust coke is good and clean fuel, can be applied to iron making blast furnaces and rotary kiln injection, is good raw materials for making molded coal, and greatly improves use value of the fine coal and economic benefit of enterprises.
