An
active carbon-based
flue gas desulfurizer is prepared by the following raw materials by weight: 100-120 parts of
active carbon, 7-9 parts of
polyvinyl alcohol, 22-24 parts of quicklime, 4-6 parts of
sodium carbonate, 26-28 parts of
chitosan, 3-4 parts of Arabic gum, 1-2 parts of
sodium alginate, 30-34 parts of meerschaum, 10-12 parts of wormwood, 20-24 parts of licorice, 20-24 parts of herba andrographitis, 2-3 parts of coconut
fatty acid monoethanolamide, 4-5 parts of auxiliary agents, and a proper amount of water. By using Chinese herbal medicines such as wormwood, licorice, and herba andrographitis to process
active carbon, the desulfurizer of the invention not only has good
adsorption effect, but also has
antibacterial effect; by using meerschaum and
chitosan, the desulfurizer of the invention has good adsorptivity, good
ion exchange performance, and high
temperature resistance, can save active carbon, and causes no secondary
pollution; the desulfurizer of the invention is not liable to disintegration, is rapid and thorough for
flue gas desulfurization, is also applicable to water desulfurization, is simple in preparation and easy to regenerate, and has good
economic benefits.
