Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic purification, in particular to a glass fiber reinforced plastic acid mist purification tower. Background Art

[0002] With the increasing degree of industrialization, the waste gas pollution caused by it has also attracted more and more attention. In the chemical, electroplating, mechanical processing and pickling production processes, a large amount of acid mist gas is generated. These acid mist gases are very harmful to the human body and the environment. Usually, these harmful gases must be strictly treated to meet the comprehensive emission standards of atmospheric pollution before they can be discharged into the atmosphere. Generally, an acid mist purification tower with a spray device is used to purify the acid mist. The main working principle is to introduce the acid mist waste gas into the purification tower and pass through the packing layer upward. In this process, the upward waste gas and the downward sprayed chemical reagents are fully contacted, absorbed and neutralized by gas-liquid two-phase. After purification, the acid mist waste gas is dehydrated and defogged by the demister plate and then discharged into the atmosphere by the fan.

[0003] However, the glass fiber reinforced plastic acid mist purification tower in the prior art can only spray within a fixed range in the horizontal direction because the spray angle is usually set to be fixed. When the spray range needs to be expanded according to the increased exhaust gas range, the spray range is limited, thereby reducing the purification efficiency. Utility Model Content
