Abstract
This paper designs a bubbling type of desulfurization reactor, which simulates flue gas nitrogen and sulfur dioxide according to a certain flow ratio, equipped with absorber through into the bubbling type desulfurization absorb and reactor by iodine volume method, measures import and export of SO2 concentration and pH value of absorber. The desulfurization rate of fly ash slurry is measured in the small drum bubble desulfurization reactor device. Results show that increasing the concentration of fly ash and entrance SO2 concentration, and decreasing particle size of fly ash will increase the desulfurization rate of fly ash slurry. The main mechanisms of fly ash desulfurization are physical adsorption and chemical adsorption.
