Abstract:
A cyclone separator for use between an upper and a lower tube sheet, the cyclone comprising:a) a substantially vertical cyclone body having a closed bottom end and a top end fixed with respect to the upper tube sheet, the cyclone body defining a feed gas inlet at its top end, the feed gas inlet extending above the upper tube sheet for receiving a particle-contaminated gas stream therefrom, the cyclone body further defining a sidewall of the cyclone body, the sidewall defining a plurality of discharge openings located between the upper and the lower tube sheets for discharging particles and a minor amount of an underflow gas stream; b) one or more swirl vanes located proximate the gas inlet to induce centripetal acceleration of the particle-contaminated gas stream; c) a gas outlet tube defining a clean gas inlet in a top end of said gas outlet tube, said clean gas inlet located centrally within the cyclone body for receiving a purified gas stream and said gas outlet tube further defining a clean gas outlet located below the lower tube sheet for discharging the purified gas stream, the gas outlet tube extending through the closed bottom end of the cyclone body and further extending through the lower tube sheet.
