<p>A plant for purifying air polluted with organic industrial products which originates from industrial processes such as painting, printing and shoe manufacture, comprising a catalyst bed consisting of oxides of metals chosen from the group comprising Cr, Mn, Fe, Co, Ni, Cu, Zn, Sn, Ba, La and Ce, through which the air is passed to obtain low-temperature combustion of said pollutants. The polluted gaseous stream can also originate from a pollutant accumulation vessel (in the form for example of a filter comprising ceramic absorbents or activated carbon) from which it is released under programmed conditions, and with automatic regeneration of the accumulation vessel.</p> |
