Abstract

The invention discloses an absorption tower and a flue gas desulfurization system. The absorption tower comprises a tower body, a spraying assembly, a synergistic ring and a connecting piece. The tower body is provided with a flue gas flow channel, the flue gas flow channel is provided with a flue gas inlet side and a flue gas outlet side, and the flue gas outlet side is located above the flue gasinlet side in the vertical direction. The synergistic ring and the spraying assembly are sequentially arranged in the flue gas flow channel, and the synergistic ring is located on the side, closer tothe flue gas inlet side, of the spraying assembly. The synergistic ring is connected with the spraying assembly through the connecting piece. An anti-corrosion layer is arranged on the inner wall ofthe tower body, the synergistic ring and the anti-corrosion layer are arranged at intervals, and an annular gap is formed between the synergistic ring and the anti-corrosion layer. According to the scheme, the problem that an anti-corrosion layer on the inner wall of an existing absorption tower can be damaged when a synergistic ring is installed can be solved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an absorption tower and a flue gas desulfurization system. Background technique [0002] During the production activities of the power plant, a large amount of sulfur-containing flue gas will be produced, and the sulfur dioxide in the flue gas will cause damage to the environment, so it is necessary to desulfurize the flue gas in the power plant. At present, power plants usually have a flue gas desulfurization system. The core equipment of the flue gas desulfurization system is the absorption tower. In order to improve the desulfurization efficiency and reduce the cost, the absorption tower is usually equipped with a synergistic ring. [0003] Due to the strong corrosiveness of sulfur-containing flue gas, the anti-corrosion performance of the absorption tower is an important factor affecting its service life and operational safety; however, the synergistic rings in ...
