The invention discloses a
drying, carbonizing and activating integrated method for
activated carbon preparation. The
drying, carbonizing and activating integrated method comprises the steps of water-containing feeding, catalytic decoking,
fuel gas distribution, high-temperature
combustion, activated
combustion, integrated activating, integrated carbonizing and integrated
drying. According to the integrated method, combustible components in dried
tail gas are utilized to form high temperature for activation, then
waste heat of activated
tail gas is utilized for
carbonization, and
waste heat of carbonized
tail gas is further utilized for drying, so that energy self-circulation is formed; meanwhile, according to the integrated method, self-contained
water vapor of the raw materials is utilized, and
water vapor is reversely provided for the activation process through circulation of the self-contained
water vapor; the method can realize integration of drying,
carbonization and activation processes in bamboo
activated carbon production, and has the characteristics of energy self-supply, high production efficiency and low process
energy consumption. The method not only can be applied to preparation of
activated carbon by taking bamboo as a
raw material, but also can be applied to preparation of activated carbon by taking wood, coconut shells, fruit shells and other
biomass raw materials.
