Abstract

The invention provides a high activated carbon powder waste gas treatment material. The high activated carbon powder waste gas treatment material comprises the following materials in parts by weight:51-55 parts of graphene, 30-32 parts of coconut shell activated carbon powder, 7-10 parts of nano silicon dioxide, 15-20 parts of polyvinylpyrrolidone, 5-10 parts of diatomite, 10-13 parts of polyvinyl alcohol, 20-22 parts of calcined kaolin, 4-7 parts of hydroxymethyl celluloses and 5-9 parts of cordierite. According to the invention, the graphene, the coconut shell activated carbon powder and the calcined kaolin are used as raw materials, and pollutants in waste gas are coordinately absorbed by the materials, so that the absorption rate can be increased, and toxic and harmful substances canbe effectively adsorbed; and a preparation method provided by the invention is simple, the cost is low, the powdery materials are mixed and roasted at high temperature to prepare carbon powder with high activity, and the carbon powder is suitable for adsorbing various waste gases.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a high-activated carbon powder waste gas treatment material and a preparation method thereof. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc., and the production of domestic waste gas from human life, the exhaust gas has a strong smell, which seriously pollutes the environment and affects human health. There are many types of pollutants in exhaust gas, their physical and chemical properties are very complex, and their toxicity is also different. The exhaust gas discharged from fuel combustion contains sulfur dioxide, nitrogen oxides, hydrocarbons, etc.; due to the different raw materials and processes used in industrial production, various harmful gases and solid wastes are discharg...
