In a process and equipment for cleaning industrial fumes of the type wherein the fumes are submitted to a first washing stage in a cyclonic-scrubber 1A operating as a saturator, wherein the fumes, flowing along a spiral path, are sprayed by a washing liquid, and to a second stage, wherein the fumes, leaving the saturator, flow through a Venturi-scrubber 9, the cleaning efficiency is considerably improved, both with regard to dusts collection and chiefly to the capture of polluting gases (such as SOx, NOx, Cl2, F , and so forth), by providing, downstream of the Venturi-scrubber, a further washing stage in a second cyclonic-scrubber 1B. Washing liquid in the equipment is recirculated, and tanks 12, 21, 23 may be supplied with an alkaline reagent e.g. lime. <IMAGE> |
