  • Mist Eliminator an overview | ScienceDirect Topics

    Dynamic scrubbers (Fig. ) have separation efficiency higher than that of spray towers. In the dynamic scrubber, the particulate matter is at first separated by the cyclonic effect of gas that enters tangentially. The gas stream with submicron particles then flows through wetted fan rotors, where additional liquid scrubber is supplied.

  • Quenching (scrubber) Wikipedia

    Quenching, in the context of pollution scrubbers, refers to the cooling of hot exhaust gas by water sprays before it enters the scrubber proper. Hot gases (those above ambient temperature) are often cooled to near the saturation level. If not cooled, the hot gas stream can evaporate a large portion of the scrubbing liquor, adversely affecting collection efficiency and damaging scrubber ...
