Embodiment Construction
[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0034] Such as figure 1 As shown, the present embodiment provides a kind of activated carbon preparation process, comprises the following steps:
[0035] Step 1. Drying and milling: carbonize and grind the sawdust after drying to obtain dry carbon powder.
[0036] Step 2, processing and molding: use a mold to process the carbon powder into a cylindrical carbon block, and open a number of honeycomb through holes.
[0037] Step 3. Clean the carbon block: wash the formed carbon block with water to remove impurities on the surface of the carbon block.
[0038] Step 4, drying the carbon block: drying the cleaned carbon block to remove moisture in the honeycomb through-holes of the carbon block.
[0039] Wherein, described in step 4, in the process of ...

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.
Description
technical field [0001] The invention belongs to the technical field of activated carbon preparation, and in particular relates to an activated carbon preparation process. Background technique [0002] Activated carbon is a specially treated carbon. The organic raw material is heated under the condition of isolating the air, and then reacts with the gas, and the surface is eroded to produce a microporous structure. Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, so countless small pores will be formed on the surface of activated carbon, so that activated carbon has a huge surface area and strong adsorption capacity. According to the shape of activated carbon, it is usually divided into two categories: powder and granular; granular activated carbon is also cylindrical, spherical, hollow cylindrical and hollow spherical, and irregularly shaped crushed carbon, among which cylindrical ...
