Problems solved by technology

Activated carbon is used in the industrial field for decolorization, refining, and purification of liquid phase adsorption. In terms of gas phase adsorption, powdered and granular activated carbon cannot be in close contact with toxic and harmful substances in the air, thus greatly reducing the adsorption effect.
[0004] On the other hand, the current activated carbon application technology lacks the ability to ensure that activated carbon has a good adsorption of dirt, and also enables it to decompose toxic gases such as formaldehyde, ammonia, and benzene adsorbed in activated carbon under the action of ordinary light.

Embodiment 1

[0026] Embodiment 1: The weight ratio of the raw materials used is: 23 parts of chemical activated carbon, 23 parts of coal-based granular activated carbon, 54 parts of coconut shell activated carbon, the activated carbon of three kinds of different proportions that will be selected is put into the ball mill in the ball mill, and ground into The mesh number is 500 mesh activated carbon powder. Then get 100 parts of activated carbon powder, 5 parts of nano-zinc oxide with a purity of 99%, 1.5 parts of methylcellulose, and 1.5 parts of talcum powder. The above-mentioned raw materials are sequentially added to stirring and mixing, stirring evenly to make a mixture. Then put the mixed material in a kneader (a mixer can also be used), add moderate distilled water, knead for 30 minutes, and knead it into a paste in the kneader. Then the mud paste is placed in a vacuum mud mill, and mud is honed into a uniform plasticized mud paste in the vacuum mud mill. Then put the plasticized m...

Embodiment 2

[0028] Embodiment 2: The weight ratio of the raw materials used is: 18 parts of chemical activated carbon, 25 parts of coal-based granular activated carbon, 57 parts of coconut shell activated carbon, three kinds of activated carbons with different proportions are put into a ball mill for ball milling, and ground into The mesh number is 500 mesh activated carbon powder. Then get 100 parts of activated carbon powder, 6 parts of nano-zinc oxide with a purity of 99%, 2 parts of methylcellulose, and 2 parts of talcum powder. The above-mentioned raw materials are sequentially added to stirring and mixing, stirring evenly to make a mixture. 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.

Abstract

The invention belongs to honeycomb type nano zinc oxide purifying activated carbon and a preparation method thereof. The honeycomb type nano zinc oxide purifying activated carbon is prepared from raw materials of, by weight, 17-28 parts of chemical activated carbon, 15-25 parts of coaly granular activated carbon, 50-60 parts of coconut shell activated carbon, 4-6 parts of nano zinc oxide 99% in purity, 1-2 parts of methylcellulose and 1-2 parts of talc powder. The method includes the steps of performing ball milling, raw material mixing and uniform stirring to prepare product materials, and then preparing the honeycomb type nano zinc oxide purifying activated carbon via vacuum pugging, extrusion forming, airing and sintering. By the method, the activated carbon can have an excellent contaminant absorption function, can decompose poisonous gases such as formaldehyde, ammonia and benzene absorbed therein under the action of ordinary light, in other words, has a self-purifying function, and further has the advantages of being formable, firm, durable in use, simple and feasible in method, low in pollution treatment cost, low-carbon, energy saving and good in treatment effect.
