Abstract:
Incinerator fumes processing plant comprising:a first reactor through which the fumes flow longitudinally, provided with an inlet and an outlet;absorbent injection means for injecting an absorbent into the first reactor;a second reactor having an inlet connected to the outlet of the first reactor,wherein the fumes are driven with a rotating motion so as to separate, by centrifugal effect, solid particles from gases circulating in the second reactor;means for recirculation, in the plant, of at least part of the solid particles separated in the second reactor;means for discharge of the fumes which have been dedusted of the solid particles;wherein the second reactor is mainly cylindrical and comprises three zones physically separated from one another along at least a portion of each of the three zones:a peripheral zone to gather and/or to recycle fumes charged with absorbent particles,an intermediate zone where a rotating motion is imparted to the flow, anda central zone for discharge of the scrubbed fumes;wherein the three zones of the second reactor are coaxial and substantially perpendicular to the longitudinal axis of the first reactor, and wherein the first reactor and the second reactor are so laid out in relation to each other that the fumes enter the intermediate zone of the second reactor tangentially.
