Abstract

The invention discloses an absorbing tower slurry oxidation device. The device comprises an absorbing tower, an oxidation air pipeline, a first flushing system and a second flushing system. The absorbing tower is internally equipped with a group consisting of a stirrer, a flushing nozzle and an oxidation spray gun, which are in adjacent arrangement; the two ends of the oxidation air pipeline are connected to an oxidation blower fan and the oxidation spray gun; the first flushing system and the oxidation air pipeline are connected via a water injector; and one end of the second flushing system is connected to the flushing nozzle towards the absorbing tower. The absorbing tower slurry oxidation device can improve the oxidation effect of absorbing tower slurry to further improve SO2 removal efficiency, improve the quality of gypsum, reduce the content of calcium sulfate in gypsum and facilitate neutralization and utilization of gypsum.

Description

technical field [0001] The invention relates to the technical field of limestone-gypsum wet desulfurization, in particular to an oxidation device for absorbing tower slurry. Background technique [0002] At present, for the field of limestone-gypsum wet desulfurization, the oxidation trend of the absorption tower slurry is mainly forced oxidation, which means that excessive air is introduced into the absorption tower slurry, and the sulfur in the slurry is oxidized by a large amount of oxygen to finally generate gypsum slurry. In practical engineering applications, forced oxidation can be divided into two types: one is the oxidation pipe network type; the other is: the oxidation spray gun type. The layout of the oxidation pipe network tower is complicated, the oxidation air pipe is easy to break due to vibration and other reasons, and the fixed parts in the tower are easy to break after wear. Moreover, the oxidation effect of the above two oxidation methods will be affected...
