Abstract

The invention discloses an absorption tower and a flue gas desulfurization system. The absorption tower includes a tower body, a spray assembly, a synergistic ring and a connecting piece. The tower body is provided with a flue gas flow channel, and the flue gas flow channel has a smoke inlet The gas side and the flue gas outlet side, in the vertical direction, the flue gas outlet side is located above the flue gas inlet side; the synergistic ring and the spray assembly are sequentially arranged in the flue gas flow channel , and the booster ring is located on the side of the spray assembly closer to the side of the flue gas inlet; the booster ring is connected to the spray assembly through the connecting piece; the inner wall of the tower body An anti-corrosion layer is provided, the synergy ring and the anti-corrosion layer are arranged at intervals, and an annular gap is formed between them. The above solution can solve the problem of destroying the anti-corrosion layer of the inner wall of the current absorption tower when the synergistic ring is installed.

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 process of the power plant, a large amount of sulfur-containing flue gas will be generated, 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, a synergistic ring is usually installed in the absorption tower. [0003] Because sulfur-containing flue gas is highly corrosive, the anti-corrosion performance of the absorption tower is an important factor affecting its service life and operation safety; however, the synergistic ring in the prior art...
