Abstract

The invention discloses mixed desulfurization dedusting particles having a bactericidal effect, and is characterized in that the mixed desulfurization dedusting particles are prepared from the following raw materials in parts by weight: 95-110 parts of activated carbon, 30-40 parts of diatomite, 2-3 parts of alum, 2-3 parts of sodium silicate, 3-4.5 parts of sodium carbonate, 3-5 parts of cellulose acetate, 9-12 parts of nano titanium dioxide, 1-2 parts of an adhesive chitin fiber, 1-2 parts of tetradecyl dimethyl benzyl ammonium chloride, 8-12 parts of hargil, 3-5 parts of wood charcoal, 4-6 parts of an adsorption auxiliary agent, and a proper amount of water. The formula is reasonable; with addition of sodium carbonate, sodium silicate, nano titanium dioxide and the like, the desulfurization effect is increased; activated carbon and diatomite are made into particles, the specific surface area is large, and a pore structure is reasonable; with addition of tetradecyl dimethyl benzyl ammonium chloride, the mixed desulfurization dedusting particles have the good bactericidal effect; and the mixed desulfurization dedusting particles can absorb various solutes and free gases, can effectively remove acidic or volatile harmful gases, and are suitable for industrial dry desulfurization, automobile tail gas desulfurization and the like.

Description

technical field [0001] The invention relates to a desulfurization activated carbon and a preparation method thereof, in particular to a mixed desulfurization and dust removal granule with bactericidal effect and a preparation method thereof. Background technique [0002] At present, the pollutants in the air are mainly gases produced by industrial fuel combustion, vehicle exhaust, and toxic and harmful gases produced in production, such as hydrogen sulfide or sulfur dioxide gas. Among the many desulfurization methods, one is activated carbon adsorption. Although activated carbon can adsorb a variety of acid gases, the price of activated carbon is relatively high, and the desulfurization efficiency is low, which increases the cost. In the present invention, activated carbon is combined with diatomite with special pores, and various functional substances are added to make granular substances, so that the desulfurizer is easy to fix, safe and non-toxic, has strong adsorption pe...
