Carbonization-activation integrated activated carbon production apparatus

Abstract

The purpose of the invention is to provide a carbonization-activation integrated activated carbon production apparatus. The structure of a conventional activated carbon furnace is improved, so that the two-step method in which first carbonization and then activation are carried out on the activated carbon is changed into a manner that carbonization and activation are completed in one system, two-in-one furnace for short. The carbonization-activation integrated activated carbon production apparatus is characterized in that a movably connected steam jacket is added outside a rotary kiln, the bottom of the jacket is a firebox, the top of the jacket is an insulating water tank, steam pockets are arranged on the water tank, an automatic feeder is designed on one end of the rotary kiln, a discharge screw conveyer is designed on the other end of the rotary kiln, dried and weighed material is carbonized and activated and is fed from one end of the rotary kiln in a clockwise rotating manner, the activated material is discharged out from the other end of the rotary kiln in a counterclockwise rotating manner, the production is intermittent, the material is dried by residual heat after heat exchange, and intermediate steps are reduced. The process is suitable for the production of activated carbon with various activity requirements, and the stability of product quality is favorably enhanced, heat energy is effectively recycled, the production process is shortened, energy consumption is reduced, the heat efficiency is increased, and novel production process equipment is provided for the production of various specifications of activated carbon.

Description

technical field [0001] The patent of the invention relates to a carbonization and activation integrated activated carbon production device, which belongs to the field of activated carbon energy-saving equipment manufacturing. Background technique [0002] The existing activated carbon production methods are summarized into two types, one is a two-step process, such as reverberatory furnace, direct-heating rotary kiln, carbonization is first performed to form a semi-finished product with a certain porosity and strength, that is, carbonized material, and then transferred to refractory bricks The masonry multi-layer furnace is fed with dry steam and reacted for several hours in an environment of 900-1000°C to form activated carbon products; the other is a one-step process, using an externally fired rotary kiln to input the formed carbon strips into the kiln and heat them first Carbonization, the hot flue gas produced by carbonization supplies heat to the peripheral boiler and g...

[0002] The existing activated carbon production methods are summarized into two types, one is a two-step process, such as reverberatory furnace, direct-heating rotary kiln, carbonization is first performed to form a semi-finished product with a certain porosity and strength, that is, carbonized material, and then transferred to refractory bricks The masonry multi-layer furnace is fed with dry steam and reacted for several hours in an environment of 900-1000°C to form activated carbon products; the other is a one-step process, using an externally fired rotary kiln to input the formed carbon strips into the kiln and heat them first Carbonization, the hot flue gas produced by carbonization supplies heat to the peripheral boiler and generates steam. When the requirements are met, the steam is directly passed into the interior of the outer kiln through the pipeline. Under the joint action of the bottom combustion chamber heat and the internal steam heat After a few hours, the activated carbon index is reached. Although the dry steam participates in dry distillation and pyrolysis in the rotary kiln, the steam heating method is on the upper part of the material, the product has poor absorption, long reaction time, high coal consumption, and serious pollution.
