Uniform internal heating stirring type activation kiln

Abstract

The invention discloses a uniform internal heating stirring type activation kiln, and belongs to the field of activated carbon. The uniform internal heating stirring type activation kiln comprises a kiln body, a feeding mechanism, a flow guide stirring mechanism, a water seal mechanism, a discharging mechanism and a hot blast stove, and the feeding mechanism is arranged on the side wall of the kiln body; the kiln main body mainly comprises a kiln upper cover and a kiln lower body, the kiln lower body mainly comprises a hot-blast stove body, a hot-blast stove shell and a lower body shell fixedly connected with the hot-blast stove shell, and the flow guide stirring mechanism is connected in the lower body shell; the kiln has a stirring effect and also has the effect of transporting activators; when the flow guide stirring paddles rotate to any place, the activators is conveyed to any place; the flow guide stirring paddles are uniformly distributed in the material layer; the activated material layer with the thickness of two meters is simultaneously stirred from inside to outside, is simultaneously heated and is in contact with the activators so that the activation is uniform, the specific surface area of the activated carbon is large, the activation time is shortened, and the single-machine productivity is high.

Description

technical field [0001] The invention relates to the technical field of activated carbon, in particular to an activation kiln with uniform internal heat stirring. Background technique [0002] The existing activated carbon production equipment currently on the market includes physical method and chemical method equipment. The physical method equipment includes: ①Sleep activated kiln, the product quality is good, the iodine value is 1050, and the output is 4 tons in 24 hours, but the investment is large per day. The table kiln needs more than 4 million yuan, and it is difficult and expensive to start and stop the furnace, and has strict requirements on the volatile content of the carbonized material; ②Integrated furnace, the quality of the product produced is poor, and the actual iodine value is around 700-800; ③Rake type furnace investment Less, the product quality is good, but the production capacity is low, 200 kg in 5 hours for a single machine, even a mechanical rake can ...
