Activated carbon diatomite particles capable of rapid purification of flue gas and preparation method thereof

Abstract

The invention discloses activated carbon diatomite particles capable of rapid purification of flue gas, and is characterized in that the activated carbon diatomite particles are prepared from the following raw materials in parts by weight: 105-110 parts of wooden activated carbon, 35-40 parts of diatomite, 1-2 parts of tripotassium citrate, 4-6 parts of expanded perlite, 3-5 parts of ammonium chloride, 2-3 parts of zirconium silicate, 6-9 parts of nano kaolin, 4-6 parts of nano silica, 3-5 parts of copper sulfate, 1-2 parts of rosin-polythylene oxide ester, 3-5 parts of methyldiethanolamine, 4-6 parts of an adsorption auxiliary agent, and a proper amount of water. The formula is reasonable; with addition of nano kaolin and expanded perlite, much surface pores exist, and the porosity is high; with addition of methyldiethanolamine, the activated carbon diatomite particles have a flue gas rapid purifying effect; with addition of the adsorption auxiliary agent, the activated carbon diatomite particles have special porousness, and prolong the contact time with gas; and activated carbon can quickly adsorb various solutes and free gases, and is high in activity, high in desulfurization precision, and suitable for industrial dry desulfurization, automobile tail gas desulfurization, daily air purification and the like.

Description

technical field [0001] The invention relates to a desulfurization activated carbon and a preparation method thereof, in particular to an activated carbon diatomite particle capable of rapidly purifying flue gas and a preparation method thereof. Background technique [0002] Wet FGD technology uses a solution or slurry containing absorbent to desulfurize and treat desulfurized products in a wet state. This method has the advantages of fast desulfurization reaction speed, simple equipment, and high desulfurization efficiency. However, severe corrosion, high operation and maintenance costs and It is easy to cause secondary pollution and other problems. The desulfurization absorption and product treatment of the dry FGD technology are carried out in a dry state. This method has the advantages of no sewage waste acid discharge, less corrosion of equipment, no obvious cooling of the flue gas during the purification process, and high flue temperature after purification, which is be...

[0002] Wet FGD technology uses a solution or slurry containing absorbent to desulfurize and treat desulfurized products in a wet state. This method has the advantages of fast desulfurization reaction speed, simple equipment, and high desulfurization efficiency. However, severe corrosion, high operation and maintenance costs and Easy to cause secondary pollution and other problems

The desulfurization absorption and product treatment of the dry FGD technology are carried out in a dry state. This method has the advantages of no sewage waste acid discharge, less corrosion of equipment, no obvious cooling of the flue gas during the purification process, and high flue temperature after purification, which is beneficial to the chimney. Exhaust diffusion, less secondary pollution, etc., but there are problems such as low desulfurization efficiency, slow reaction speed, and large equipment
