Integrated dust removal and desulfurization tower

Abstract

The invention relates to the technical field of desulfurization towers, in particular to an integrated dust removal and desulfurization tower which comprises a tower body, a slurry pond, a spraying layer and a demisting layer, and the slurry pond, the spraying layer and the demisting layer are arranged in the tower body and sequentially distributed from bottom to top. A synergistic tray is arranged in the integrated dust removal and desulfurization tower. The synergistic tray is arranged between the slurry pond and the spraying layer. The synergistic tray is provided with a plurality of partition plates. The synergistic tray is divided into a plurality of blocks by the partition plates. A plurality of elliptical through holes are formed in the bottom of the synergistic tray. The synergistic tray is positioned above an air inlet of the tower body. The synergistic tray is divided into the plurality of small blocks by the partition plates, so that foam can be better deposited in the small blocks of the synergistic tray, a foam layer is thicker, and the contact area is better increased. The through holes of the synergistic tray are elliptical, so that the strength of the formed foam is lower than that of the foam formed by the circular holes. Foam is easy to break, and more slurry mist is splashed to be in contact with smoke. The dust removal and desulfurization effects are better.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to an integrated dust removal and desulfurization tower. Background technique [0002] The lime-gypsum wet flue gas desulfurization process uses lime as the desulfurization absorbent. The powdered quicklime is mixed with water to make an absorption slurry. In the absorption tower, the absorption slurry is mixed with the flue gas. The sulfur dioxide in the flue gas is mixed with the slurry. The alkaline substances and the blown oxidizing air carry out a chemical reaction to absorb and remove sulfur dioxide, and the final product is gypsum. The clean flue gas after desulfurization is discharged through the chimney through the demister to remove the mist. The effect of the dedusting and desulfurization tower of the prior art is not good. Contents of the invention [0003] The purpose of the present invention is to provide an integrated dust removal and desulfurizatio...
