Activated carbon preparation raw material activation treatment process

Abstract

The invention provides an activated carbon preparation raw material activation treatment process, which is cooperatively completed by a mounting bottom plate, a [-shaped frame, a feeding mechanism, asweeping mechanism and a collecting mechanism. The problems as follows can be solved, namely in the activated carbon preparation raw material activation treatment process, a powdery adhesive on the surfaces of the activated carbon preparation raw materials needs to be manually cleaned and removed by using a cleaning device, in the period, the number of granular activated carbon raw materials whichusually need to be activated is large, the labor intensity of manual operation is high, it is difficult to completely and manually remove the adhesive powder attached to the periphery of the surfaceof the stacked granular activated carbon raw materials, repeated cleaning treatment needs to be carried out, the working efficiency of activation treatment work is reduced, powder falling in the cleaning process cannot be effectively collected, secondary pollution to the granular activated carbon cannot be avoided, and the cleaned granular activated carbon cannot be conveyed and collected in time.

Description

technical field [0001] The invention relates to the technical field of activated carbon preparation, in particular to an activated carbon preparation raw material activation treatment process. Background technique [0002] Activated carbon, as a porous adsorbent, is a non-crystalline substance composed of fine graphite-like crystallites and hydrocarbons after carbonization and activation of carbonaceous raw materials. The types of activated carbon are diverse because of their appearance, shape, raw materials, manufacturing methods and uses. According to the external shape, it is usually divided into powdered activated carbon and granular activated carbon. Powdered activated carbon is mostly wood activated carbon. Because of the problems of easy blockage of filter surface and difficult separation of powder, it fails to meet the use standards of some industries. Therefore, granular activated carbon has received more and more attention and research. It has a certain shape, hig...

Problems solved by technology

[0003] The main purpose of adding binder is to solve the problems of non-cohesiveness of the raw material itself, difficult molding, unsatisfactory product strength and surface smoothness, etc. In the actual production process, the activated carbon preparation raw materials need to be activated, that is, to adhere The excess binder powder on the surface of granular activated carbon is removed to improve the strength and adsorption performance of activated carbon. However, the following problems often exist in the activation process of raw materials for activated carbon preparation: a. In the process of activation of raw materials for traditional activated carbon preparation, The granular activated carbon raw materials are often placed on the work shelf manually, and then the powdery adhesive on the surface is cleaned and removed by cleaning equipment. During this period, the amount of granular activated carbon raw materials that usually needs to be activated is relatively small. Many, manual work is labor-intensive, and it is difficult to completely remove the adhesive powder attached to the surface of the granular activated carbon raw materials piled up by hand, and multiple cleaning treatments are required, which reduces the work of activation treatment. Efficiency, b. During the activation treatment of raw materials for traditional activated carbon preparation, it is difficult to transport granular activated carbon raw materials in batches to make them fall into the cleaning device one by one, and it is also impossible to effectively collect the powder falling during the cleaning process to avoid particle damage. Granular activated carbon for secondary pollution, and it is impossible to transport and collect the cleaned granular activated carbon in time
