Problems solved by technology

[0004] The present invention provides a kind of porous activated carbon preparation process, the purpose is to solve the following problems when the porous cylindrical activated carbon is formed and opened: (1) during the extrusion molding process of the carbon powder, the distribution density of the carbon powder is uneven, As a result, the strength of each part of the formed cylindrical activated carbon is different, which reduces the molding quality of the cylindrical activated carbon; (2) The internal cohesion of the cylindrical activated carbon after extrusion is not strong, and the cylindrical activated carbon is easy to be formed during the opening process. Internal cracks will also reduce the molding quality of cylindrical activated carbon

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 porous activated carbon preparation process, comprising the following steps:

[0035] Step 1. Drying and milling: After the sawdust is dried, it is carbonized and pulverized to obtain dry charcoal powder.

[0036] Step 2, processing and forming: the carbon powder is mixed with additives and then extruded into a cylindrical carbon block.

[0037] Step 3, opening pores: opening pores on the surface of the formed cylindrical carbon block.

[0038] Among them, step 2 and step 3 adopt such as Figure 2 to Figure 6 A kind of porous activated carbon preparation machinery as shown is cooperated and completed, and described porous activated carbon preparation machinery comprises horizonta...

Abstract

The invention belongs to the technical field of activated carbon, and specifically relates to a preparation process of porous activated carbon, which includes the following steps: step 1, drying and grinding: carbonizing and grinding the sawdust after drying, to obtain dry carbon powder; step 2, processing and molding: Extrude the carbon powder, and then use a mold to process the carbon powder into a cylindrical carbon block; step 3, open pores: open pores on the surface of the formed cylindrical carbon block; wherein, steps 2 and 3 use a porous Activated carbon preparation is mechanically coordinated. The invention reduces the strength difference of each part of the cylindrical activated carbon after molding, and improves the molding quality; the invention reduces the extrusion force of the plunger on the activated carbon during the process of opening the cylindrical activated carbon, and avoids the need for cylindrical activated carbon. There are cracks inside.

Description

technical field [0001] The invention belongs to the technical field of activated carbon, and in particular relates to a preparation process of porous activated carbon. 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. Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbonization 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 ...
