Internal heating type reduction activated carbon production converter

Abstract

The invention relates to an internal heating type reduction activated carbon production converter which comprises a combustion room, a first retaining ring, an activation chamber, heat-insulating / energy-storing refractory bricks, a second retaining ring, a carbonization chamber, a multi-inclination-angle raising plate, a push type multi-inclination-angle raising plate, a drying and plasticization chamber and a feeding spiral conveyer, wherein the drying and plasticization chamber, the carbonization chamber, the activation chamber and the combustion room are sequentially communicated and connected; the inner diameters of the drying and plasticization chamber, the carbonization chamber and the activation chamber are sequentially reduced; the feeding spiral conveyer is arranged at the inlet of the drying and plasticization chamber; the push type multi-inclination-angle raising plate is arranged in the drying and plasticization chamber; the multi-inclination-angle raising plate is arranged in the carbonization chamber; the inner walls of the carbonization chamber and the activation chamber are respectively provided with a layer of heat-insulating / energy-storing refractory bricks; and the retaining rings are respectively arranged at discharge ports of the carbonization chamber and the activation chamber. The internal heating type reduction activated carbon production converter can prevent the material from falling at the tail part of the converter, realizes uniform carbonization, achieves favorable activation effect, can maximize the activated carbon yield and fully utilize heat in the converter, and is stable in product quality, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a converter for producing activated carbon, in particular to a converter for producing internal heating variable-diameter activated carbon. Background technique [0002] At present, wood-based activated carbon is basically produced using converters. The production quality of converters is easy to control, and the tail gas can be recycled, which is more environmentally friendly. However, most of the current converters are equal-diameter converters. The disadvantage is that once the diameter of the converter is determined, the amount of feed is basically determined. The output is also determined. When there is too much feed, the material will fall from the furnace tail or block the furnace body, resulting in poor exhaust and affecting the quality; The volume gradually decreases. In the final stage of carbonization and the activation stage, the volume shrinks to 1 / 6~1 / 9 of the raw material. The effective use of space in the furnac...

[0002] At present, wood-based activated carbon is basically produced by converters. The production quality of converters is easy to control, and the tail gas can be recycled, which is more environmentally friendly. However, most of the current converters are equal-diameter converters. The disadvantage is that once the diameter of the converter is determined, the amount of feed is basically determined. The output is also determined. When there is too much feed, the material will fall from the furnace tail or block the furnace body, resulting in poor exhaust and affecting the quality; The volume gradually decreases. In the final stage of carbonization and the activation stage, the volume shrinks to 1 / 6~1 / 9 of the raw material. The effective use of space in the furnace body is very small, and most of the heat runs away from the upper part, resulting in a lot of waste of heat sources. The temperature is above 220 degrees, which also causes the activation material to be heated unevenly and over-burned, resulting in unstable quality
