The working principle of the mist eliminator is similar to the demister. The flue gas passes through the curved passage of the demister, and the droplets entrained in the air flow are separated by the inertial force and the gravity. The defogger system is composed of a defogger. The body and the flushing system are composed. The rinsing system consists of flushing pipes, nozzles, support frames, support beams and related links, fixing, and seals, which are widely used in desulfurization systems.
