Embodiment 1

[0023] Embodiment 1: Select 25 parts of chemical activated carbon, 16.7 parts of coal-based granular activated carbon, and 58.3 parts of coconut shell activated carbon. Put the selected three different proportions of activated carbon into a ball mill and grind them into activated carbon particles with a mesh size of 400-450 mesh. Then get 70 parts of activated carbon powder, 2 parts of vulcanized oil, 2 parts of carboxymethyl cellulose, and 25.5 parts of clay, and mix and stir the above-mentioned raw materials to make the product material. The product material is placed in a vacuum mud refining machine (or vacuum mud refining machine), and moderate (accounting for about 23-28% of the total weight of the product material) water is added, and the mud is kneaded into a plasticized mud paste in the vacuum mud refining machine. Place the plasticized mud paste in the extrusion molding of a steel mold equipped with honeycomb profiles, and extrude it into a profile of honeycomb-shaped...

Embodiment 2

[0025] Embodiment 2: Select 30 parts of chemical activated carbon, 21.7 parts of coal-based granular activated carbon, and 63.3 parts of coconut shell activated carbon. Put the selected three different proportions of activated carbon into a ball mill and grind them into activated carbon particles with a mesh size of 400 mesh. Then take 65 parts of activated carbon powder, 1.5 parts of linoleic acid, 4 parts of water-soluble phenolic resin, and 30.5 parts of clay, and mix and stir the above-mentioned raw materials to make the product material. Put the product material in a vacuum mud mill (or vacuum mud mill), add moderate water, and knead it into a plasticized mud paste in the vacuum mud mill. The remaining steps are the same as in Example 1, wherein the profile with a moisture content of less than 10% is put into a furnace for sintering at a sintering temperature of 900° C. for 6 hours.

Embodiment 3

[0027] Embodiment 3: Select 20 parts of chemical activated carbon, 11.7 parts of coal-based granular activated carbon, and 55.3 parts of coconut shell activated carbon. Three selected activated carbons with different proportions were put into a ball mill for ball milling, and ground into activated carbon particles with a mesh number of 500 mesh. Then take 75 parts of activated carbon powder, 1.5 parts of glycerin, 3 parts of polyvinyl alcohol, and 20.5 parts of clay, and mix and stir the above-mentioned raw materials to make the product material. Put the product material in a vacuum mud mill (or vacuum mud mill), add moderate water, and knead it into a plasticized mud paste in the vacuum mud mill. All the other steps are the same as in Example 1.

[0028] The performance of the honeycomb type purified activated carbon product: iodine adsorption value 1100~1200mg / g, benzene adsorption value mg / g≥500, specific surface m 2 / g≥1700, pH value 7~8, intensity%≥90.

Abstract

The invention belongs to a manufacturing method of honeycomb type purification activated carbon. The type purification activated carbon is prepared from 20-30 parts by weight of chemical activated carbon, 11.7-21.7 parts by weight of coal-based granular activated carbon and 55.3-63.3 parts by weight of coconut shell activated carbon. The manufacturing method comprises the following steps of: ball-milling, and selecting 65-75 parts by weight of activated carbon powder granules, 1-2 parts by weight of liquidity auxiliary agent, 2-4 parts by weight of adhesive and 20.5-30.5 parts by weight of clay as the raw materials of the honeycomb type purification activated carbon; mixing the raw materials, and uniformly stirring to prepare a product material; pug-milling in vacuum, molding by extrusion, airing and sintering to obtain the honeycomb type purification activated carbon. The interior of the honeycomb type purification activated carbon prepared by using the method can fully absorb air to form low wind resistance cross-ventilation; the activated carbon made of corresponding materials can be selected according to absorbed objects, the good absorption function of the activated carbon is ensured, and the activated carbon has firm shaping and durability. The invention has the advantages of simple and feasible method, low pollution treatment cost, low carbon, energy saving and good treatment effect.
