Abstract

The invention discloses a chemical waste gas adsorbent and a preparation method thereof. The adsorbent is prepared from, by weight, 30-35 parts of calcium carbonate fiber, 20-25 parts of tetrabutyl titanate, 5-10 parts of shell activated carbon, 7-10 parts of alginic acid, 7-9 parts of pyrite cinder, 10-15 parts of bamboo charcoal powder, 3-5 parts of silica sol, 20-30 parts of volcanic rock, 5-7 parts of nano carbon dioxide, 2.1-3.5 parts of cellulose ether, 1-3 parts of methyl triethoxysilane, 9-12 parts of jute pulp and a proper amount of water. The chemical waste gas adsorbent is high in adsorption and can efficiently remove main pollutants such as volatile organic substances, inorganic matter, hydrogen sulfide, ammonia and mercaptan and various odors, the deodorizing efficiency can reach 98% or above, and the antibacterial and air purifying effects are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical waste gas treatment, in particular to a chemical waste gas adsorbent and a preparation method thereof. Background technique [0002] Chemical waste gas refers to the poisonous and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health. The composition of chemical waste gas produced by different chemical production industries varies greatly. For example, the waste gas produced by the chlor-alkali industry mainly contains chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene, etc., and the waste gas produced by the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc. At present, the treatment effect of solid pa...
