Preparation method of filtering adsorption material

Abstract

The invention relates to a preparation method of a filtering adsorption material. Drying treatment equipment is used and comprises a box, a sealing door is movably mounted on the front surface of thebox, air supply devices are correspondingly and fixedly mounted on the left side and the right side of the box, and a mounting plate is fixedly mounted on the back surface of the interior of the box.According to the preparation method of the filtering adsorption material, each layer of blocky activated carbon is divided into single isolation cabins, dry hot air is directly introduced from the bottom of each isolation bin, so that hot air in each isolation bin dries the blocky activated carbon in the single isolation bins, the dried air in each isolation bin can directly hit the space betweenthe adjacent isolation bins and rises to the top, it is guaranteed that moisture evaporated out of each isolation bin cannot influence the activated carbon in any other isolation bin, the mode that the hot air is intensively introduced and then uniformly flows into each isolation bin is adopted, and it is guaranteed that the hot air in each isolation bin is dry and uniform.

Description

technical field [0001] The invention relates to the technical field of activated carbon preparation, in particular to a method for preparing a filter adsorption material. Background technique [0002] Activated carbon is the most used filter and adsorption material, among which activated carbon is a kind of specially treated carbon, and block Martian is a carbon block structure material with high density and high porosity. Block activated carbon can be used as needed The shapes are different from those designed, mainly including cylindrical, elliptical cylindrical and cube. The preparation process of activated carbon needs to go through a series of processes such as carbonization, activation, etc., and finally it is dried to prepare activated carbon. However, the existing ones for There are some problems in the use of block activated carbon drying equipment: [0003] Most of the existing drying equipment uses a large box to dry the bulk activated carbon that needs to be dri...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing drying equipment uses a large box to dry the bulk activated carbon that needs to be dried in the box through the heating wire arranged on the inner wall of the box or the way of hot air. The box is larger, and the heat generated on the inner wall for drying spreads from the edge to the center, so the temperature of the center of the box is lower than the temperature at the edge of the inner wall, so for the block located in the center The activated carbon has low drying effect and drying efficiency, and because the heat is spread, the moisture evaporated from the block activated carbon at the edge will shuttle in the activated carbon with the flow of hot air. Therefore, some of the water will be absorbed by the activated carbon during its shuttle process, and the traditional drying equipment is to place the activated carbon layer by layer and then put it into it for drying, so that the water evaporated from the activated carbon in the lower layer will be absorbed by the upper layer. The heat is absorbed, and the heat is rising, so although the upper activated carbon has more heat, the heat with moisture in the traditional drying box will be affected by the temperature difference between the inside and outside when it is discharged from the top, resulting in the moisture in it. Condensate down and fall on the upper activated carbon again, resulting in repeated drying process and unsatisfactory effect, and the drying time is too long
