Abstract

Reaction tower or continuous and counter-current bleaching, mainly applicable in the cellulose industry, which is characterized by comprising a container formed by two tubes or communicating vessels, located vertically side by side or one inside the other according to coaxial arrangement, and communicated by its lower part, one of whose vessels receives at its upper end the material to be treated that leaves the upper end of the other vessel already treated, by this exit end of the material, and in other areas of the path of the matter to be treated, suitable liquids are introduced for the treatment and washing, so that these circulate countercurrent with respect to the direction of advance of the matter to be treated and exit through the entrance mouth of the latter, the matter or mass is periodically driven by means impellers arranged in various sections of the interior of said cups.
