Activated carbon preparation process

The invention belongs to the technical field of activated carbon preparation, and particularly relates to an activated carbon preparation process which comprises the following steps: step 1, drying and grinding: carbonizing and grinding sawdust after drying to obtain dried carbon powder; step 2, processing and forming: processing the carbon powder into a cylindrical carbon block by using a mold, and forming a plurality of honeycomb-shaped through holes; step 3, cleaning of the carbon block: washing the formed carbon block with water to remove impurities on the surface of the carbon block; step4, drying of the carbon block: drying the cleaned carbon block to remove moisture in honeycomb-shaped through holes of the carbon block, wherein the drying process of the cleaned carbon block in thestep 4 is completed by adopting an activated carbon preparation machine in a matching manner. The invention solves the problems that at present, when the interiors of cylindrical activated carbon honeycomb holes are dried, part of moisture on the inner walls of the honeycomb holes permeates into the surface layers of activated carbon, sufficient drying is difficult, and moisture residues are likely to be caused, and conveying and drying cannot be conducted synchronously, and the machining efficiency is low.
