Embodiment Construction

[0023] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Such as Figure 1~3 As shown, a flue gas desulfurization absorption tower includes a tower body 1 and a flue gas outlet 2 arranged on the upper part of the tower body 1. The middle part of the tower body 1 is provided with a flue gas inlet 3, and the tower body 1 is sequentially arranged from bottom to top. The spray layer 4 and the demister layer 5, the bottom of the tower body 1 is provided with a slurry pool 6, the slurry pool 6 is provided with a stirring device, the slurry in the slurry pool 6 communicates with the spray...

Abstract

The invention belongs to the technical field of flue gas desulfurization and in particular relates to a flue gas desulfurization absorption tower which comprises a tower body and a flue gas outlet, wherein the flue gas outlet is formed in the upper part of the tower body; a flue gas inlet is formed in the middle of the tower body; a spraying layer and a demisting layer are sequentially arranged from bottom to top inside the tower body; a slurry tank is arranged at the bottom inside the tower body; a stirring device is arranged inside the slurry tank; an air flow distribution device is arrangedbetween the flue gas inlet and the spraying layer; the air flow distribution device comprises upper-layer grids and lower-layer grids; the upper-layer grids and the lower-layer grids are arranged ina staggered manner; intervals are arranged between the upper-layer grids and the lower-layer grids. Due to adoption of two layers of grids, the flue gas distribution effect can be improved; in addition, since the two layers of the grids are arranged in the staggered manner, the flue gas distribution uniformity degree can be further increased; due to adoption of the stirring device, axial reciprocation movement can be achieved while stirring is achieved, stirring can be carried out through a moveable device, dynamic stirring can be achieved, and thus the stirring effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of flue gas desulfurization, and in particular relates to a flue gas desulfurization absorption tower. Background technique [0002] The desulfurization tower is a tower equipment for desulfurization of industrial waste gas. The desulfurization tower is mainly used to remove sulfur oxides in the waste gas. The desulfurization tower continues to develop, forming various types such as Venturi type, swirl plate type, swirl column type, floating ball type, sieve plate type, and pneumatic emulsification type. However, the existing desulfurization tower has the problems of poor flue gas distribution uniformity and unsatisfactory mass transfer effect in the tower. For this reason, my country's utility model patent application number 200820100630.6 discloses a flue gas wet desulfurization absorption tower, which is equipped with a rectification device, so that the flue gas in the tower is evenly distributed, the ga...
