Embodiment 1

[0015] A method for manufacturing columnar activated carbon includes crushing and pulverizing raw coal into pulverized coal, and then adding a binder for coal blending, kneading, and molding. The molding equipment used during molding is Japan Fuji Equipment Manufacturing Co., and the model is F-150 feed pelletizing equipment, the pelletizing pressure is 6.0-8.0MPa; when blending coal, the pulverized coal is 72%, the pitch is 12%, the water is 16%, the temperature of the pulverized coal is 18℃, and the temperature of the water is 50°C; the pulverized coal used is composed of 30% bituminous coal, 35% coke powder and 35% coking coal. The raw coal and pitch are mixed according to the above ratio and then ground to 150 mesh, and then added with the corresponding weight of water, mixed evenly and kneaded for a certain period of time, and then sent to the F-150 feed manufacturing company produced by Japan Fuji Equipment Manufacturing Co. In the pelletizing equipment, under the condition ...

Abstract

The invention relates to the activated carbon manufacturing field, in particular to a method of manufacturing columnar activated carbon, and solves the problems of high production cost, environmental pollution, low productivity, etc. caused by the addition of coal tar and hydraulic shaping devices required by the prior columnar activated carbon. A shaping device adopted by the invention when shaping is a feed granulation device manufactured by Fuji Seiki Equipment Manufacture Company, and the type of the shaping device is F-150. When coal is proportioned, coal powder is 72-78 percent, asphalt is 8-12 percent, water is 12-18 percent, the temperature of the coal powder is 18-20 DEG C, the temperature of water is 50-80DEG C, and the coal powder consists of 30-45 percent of soft coal, 25-35 percent of coke powder and 30-45 percent of coking coal. With the adoption of the shaping device, the method has the advantages of low shaping pressure, moderate operation conditions, improved productivity, simple process, reduced environmental pollution, saved heat energy, reduced production cost, and significantly improved the yield of products. The technical data of the prepared finished columnar activated carbon granules can be completely in accordance with the requirements. Furthermore, the method overcomes the technical prejudice of the technical field that only coal tar and the hydraulic shaping device can ensure the shaping of coal quality and the strength of activated carbon.

Description

Technical field [0001] The invention relates to the field of activated carbon manufacturing, in particular to a method for manufacturing columnar activated carbon. Background technique [0002] Activated carbon is a kind of carbon material with developed pores.
