[0002] The demister is mainly composed of corrugated blades, plates, strips and other fixing devices. During the operation of wet flue gas desulfurization and absorption tower, "fog" with a particle size of 10-60 microns is easily generated. The "fog" not only contains water, but also dissolves sulfuric acid, sulfates, sulfur dioxide, etc. It also causes contamination and serious corrosion of fans, heat exchangers and flues. Therefore, the wet flue gas desulfurization process puts forward the requirement of demisting for absorption equipment. The function of the demister is to capture the particles and slurry droplets in the mist for treatment. The demister is generally required to work in an environment of 80°C.
[0003] The Z-shaped demister captures particulate matter in the exhaust gas during the defog process. The number of demisters will affect the storage effect. Different numbers of demisters are required for different exhaust gases. Secondly, the surface of the Z-shaped PVC plate in the demister is smooth, and the single-stage treatment effect on the exhaust gas is poor. Finally, the defogged exhaust gas may contain polluting acidic gases before it is discharged from the defogger and cannot be discharged directly. Therefore, a high-efficiency demister is proposed to address the above problems. Utility Model Content
