A kind of activated carbon preparation process

Abstract

The invention relates to an activated carbon preparation process, which uses an activated carbon preparation equipment. The activated carbon preparation equipment includes a base, a driving unit and a preparation device. The upper surface of the base is provided with the drive unit and the preparation device. The drive unit is located directly above the preparation device. The present invention can solve the existing problems in the preparation of activated carbon particles by using molds: from the activated carbon raw material entering the mold to the forming and drying stage, there is no process of cleaning the surface of the mold, so that more and more activated carbon raw materials on the surface of the mold are bonded , not only will cause the waste of activated carbon raw materials, but also cause the surface of the mold to corrode due to some chemical substances contained in the activated carbon raw materials; for the removal of activated carbon particles formed by die-casting in the mold, there are problems such as damaged and loose activated carbon particles, deformation, etc. These destroyed activated carbon particles need to be re-cast, resulting in a decrease in the production efficiency of activated carbon particles and an increase in labor.

Description

technical field [0001] The invention relates to the field of environmental protection material processing, in particular to an activated carbon preparation process. Background technique [0002] Activated carbon is a black porous solid carbon. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements; it has strong adsorption performance and is an industrial adsorbent with a wide range of uses. Activated carbon is made of carbon-containing substances as raw materials. Hydrophobic adsorbent made by high-temperature carbonization and activation; activated carbon contains a large number of micropores and has a huge specific surface area, which can effectively remove color and odor, and can remove most organic pollutants and some inorganic substances in the secondary effluent , including some toxic heavy metals; factors affecting activated carbon adsorption are: the characteristics of activated carbon; the chara...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many molds for making the appearance shape of activated carbon particles. When using molds to prepare activated carbon particles, there are the following problems: a. From the activated carbon raw material entering the mold to the molding and drying stage, there is no process of cleaning the surface of the mold, making the mold The activated carbon raw materials on the surface are more and more bonded, which will not only cause the waste of activated carbon raw materials, but also cause the surface of the mold to corrode due to some chemical substances contained in the activated carbon raw materials, shortening the service life of the mold; b. For the mold The removal of activated carbon particles formed by internal die-casting has problems such as damaged and loose activated carbon particles, deformation, etc., which makes these destroyed activated carbon particles need to be re-cast, resulting in a decrease in the production efficiency of activated carbon particles and increasing the workload.
