Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a device for detecting the corrosion resistance of demister materials. Background Art

[0002] The demister is mainly composed of corrugated blades, plates, strips and other fixing devices. During 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 dissolves sulfuric acid, sulfate, SO2, etc., and 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 the absorption equipment. The purified gas must be demisted before leaving the absorption tower. Therefore, the material of the demister needs to be corrosion-resistant, but the material of the demister needs to be tested using a corrosion resistance detection device.
