Demister (mist eliminator) is mainly composed of fixtures waveform blades, sheet, strip cards, etc., in the wet desulfurization absorber during operation, easy to produce a particle size of 10 - 60 microns, "fog" "Fog" is not only contains water, it dissolved sulfate, sulfate, sulfur dioxide, etc., but also resulted in fans, heat exchangers and flue tarnished and severe corrosion, so the wet FGD technology absorption equipment made defogging request, before the purified gas leaving the absorption column to the demister. Demister system consists demister body and flushing system. Specifically two demister body wash water pipes, nozzles, cage, support beams and associated connections, fixed, seals and other components.
