Description

[0002] The demister is mainly composed of corrugated blades, plates, strips and other fixing devices. In the wet flue gas desulfurization, the absorption tower is prone to produce "fog" with a particle size of 10-60 microns during operation. The "fog" not only contains water, but also contains sulfuric acid, sulfate, SO 2 At the same time, it also causes contamination and serious corrosion of fans, heat exchangers and flues. At the same time, the solid particles contained in the droplets on the demister baffles will form a scale layer on the blade surface. Once the demister is scaled, the scale will develop very rapidly, reducing the flow area of the channel and increasing the risk of secondary carryover.
[0003] The traditional method is to flush with water. Since the dirt adheres to the baffles, it cannot be completely removed, causing the scale layer to gradually thicken, affecting the purification efficiency.
