Device for abatement of liquid, gaseous and/or solid pollutant substances of various kind, produced by various sources, which are contained into the exhaust smokes deriving from the combustion processes of pollutant substances of various kind, and in particular but not exclusively in the case of use of civil or industrial thermic plants, and the traffic of vehicles powered by explosion engines. Device comprising at least a heating module (5), for the circulation and the abatement at large extent of the pollutant substances; and at least a module (6) for partial recovering the smokes, communicating with said heating module (5) and contained together with this latter into a flue (7), as well as suitable to let to pass part of the abated smokes to be discharged outside the flue (7) and to recover part of the same smokes, for bringing them again in to the combustion chamber (8) into which the combustion of the pollutant substances occurs, in a manner to improve the combustion of the products into the same. The abatement of the pollutant substances, circulating through some lengthened tubes (25) inserted in to the heating module (5) occurs by employing the microwaves, generated by at least a magnetron (32) and directed toward the tubes (25), in a way that the circulating hot smokes be additionally heated and be also abated by the energy peaks of the microwaves (so-called hot spots) which might attain very high temperatures, even in the range comprised preferably but not necessarily between about 1200° C and about 2600° C. |
