Problems solved by technology

[0002] Industrial flue gas desulfurization adopts sulfur dioxide into water to form sulfurous acid, and then sulfurous acid reacts with calcium carbonate in lime water slurry to form calcium sulfite, and then injects oxygen to oxidize calcium sulfite into calcium sulfate to form gypsum by-product; Absorption of sulfur dioxide in the flue gas; the existing method often uses a pressurized nozzle to spray lime water slurry into the flue gas, and then realizes the leaching and absorption of the flue gas. This method often has the disadvantage of insufficient absorption

Abstract

The invention discloses a flue gas desulfurization apparatus, comprising a desulfurization tank which is of inclined rectangular tank structure. A desulfurization inclined passage as inclined as the desulfurization tank is arranged in a tank body of the desulfurization tank; the inclined lower end of the desulfurization inclined passage is provided with a low liquid-storing trough; all desulfurizing stirring blades above liquid levels in a first desulfurizing blade-wheel rotation chamber, a second desulfurizing blade-wheel rotation chamber and a third desulfurizing blade-wheel rotation chamber, and a plurality of hollow desulfurizing holes are continuously wetted by a slurry; flue gas is continuously wetted by the lime slurry at the hollow desulfurizing holes when passing through the hollow desulfurizing holes; sulfur dioxide is mixed in water to form sulfurous acid; the sulfurous acid reacts with calcium carbonate in the lime slurry to generate calcium sulfite; therefore, sulfur dioxide in the flue gas is absorbed.

Description

technical field [0001] The invention belongs to the field of flue gas purification, in particular to a flue gas desulfurization device and a desulfurization method thereof. Background technique [0002] Industrial flue gas desulfurization adopts sulfur dioxide into water to form sulfurous acid, and then sulfurous acid reacts with calcium carbonate in lime water slurry to form calcium sulfite, and then injects oxygen to oxidize calcium sulfite into calcium sulfate to form gypsum by-product; Absorption of sulfur dioxide in the flue gas; the existing method often uses a pressurized nozzle to spray lime water slurry into the flue gas, thereby realizing the leaching and absorption of the flue gas. This method often has the disadvantage of insufficient absorption. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a flue gas desulfurization device with sufficient absorption.
