AI Technical Summary
In existing wet desulfurization absorption towers, the spray nozzles are located on the inner wall of the absorption tower, which makes it difficult for sulfur-containing waste gas to fully contact the sprayed slurry, resulting in insignificant desulfurization effect.
A baffle plate and a multi-layer nozzle structure are installed inside the absorption tower to increase the flow path of the exhaust gas and the spraying time. Multiple sprays increase the contact area, and secondary spraying is carried out through a diversion plate to improve the desulfurization effect.
By using multiple sprays and extending the flow path, the desulfurization effect of sulfur-containing waste gas is significantly improved, while saving slurry usage and avoiding backflow of flue gas.

Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of environmental protection equipment, and specifically relates to a novel wet desulphurization absorption tower. BACKGROUND
[0002] The desulfurization tower is a tower type equipment for desulfurization treatment of industrial waste gas, and is most widely applied in the initial granite masonry, which is also named granite water film desulfurization dust remover or stone water film desulfurization dust remover according to the water film desulfurization dust removal principle. Generally, sulfur is contained in working waste gas, and direct emission into the air will cause certain influence on the surrounding working environment, therefore, workers need to treat the sulfur-containing waste gas, and the desulfurization absorption tower is generally used for treating the sulfur-containing waste gas, although the sulfur in the sulfur-containing waste gas can be separated in the prior art, but there are still certain deficiencies in the specific use, and therefore, the desulfurization absorption tower needs to be improved.

The spray nozzle has a wear-resistant ring inclined downward away from the inner side wall of the absorption tower body. The wear-resistant ring is fixedly connected to the inner side wall of the absorption tower body. The wet desulfurization absorption tower provided in the application can increase the desulfurization efficiency, extend the operation cycle and reduce the corrosion of the desulfurization slurry to the inner side wall.

When the sulfur-containing waste gas flows to the center of the absorption tower through the covering protection ring and the wear-resistant ring, the spray head sprays slurry downward. At this time, the sulfur-containing waste gas located at the center position is difficult to fully contact with the slurry sprayed by the spray head, so that the desulfurization effect of the sulfur-containing waste gas is not significant enough, and there is certain limitation in use.

[0025] Example two:
[0026] Please refer to Fig. 1 and Fig. 2 As shown, the inner bottom wall of the absorption tower body 1 is fixedly connected with a collection box 15, the bottom end of one side of the collection box 15 is fixedly connected with a liquid discharge pipe 16, and the surface of the liquid discharge pipe 16 is fixedly connected with the inside of the absorption tower body 1, and the surface of the liquid discharge pipe 16 is provided with a control valve.
