摘要： A particulate filtering apparatus for dry filtering exhaust gases of a diesel engine includes at least two compartments independently arranged in parallel with respect to a flow of the exhaust gases. Each of the compartments is equipped with at least one shut-off valve for regulating the flow of gas passing through the compartment and further includes one or more filters adapted to hold the particulate and an emission device to generate a countercurrent gas pulse flow at the one or more filters. A central control unit operates and controls the at least one shut-off valve and of said emission device. Each of the at least two compartments further includes an injector operably controlled by the central control unit for the inlet of hot gases into the at least two compartments.

摘要： A granule reactor (10), an apparatus comprising said reactor and a method implemented by said apparatus are described for treating polluting agents present in industrial gases, particularly but not only, when such gases comprise NOx, volatile organic compounds (VOCs), carbon monoxide (CO), hydrocarbons and similar pollutants. The pellet reactor is adapted to be used in the treatment of industrial gases, capable of treating industrial gases and removing particulate from said gases while maintaining a constant efficiency. Moreover, a method of treating the polluting agents present in industrial gases by means of said pellet reactor, and a pellet reactor adapted to implement said method of treatment are described.

摘要： The present invention relates to a “dry” particulate filtering apparatus for diesel engines, in particular for marine diesel engines, as well as a method of operation and regeneration of said apparatus. The apparatus according to the present invention is characterised in that it comprises a plurality of independent compartments which are arranged in parallel with respect to the flow of the exhaust gases to be treated, and in that it comprises, on each of said compartments, shut-off means that allow a single compartment to be excluded from the filtering during the regeneration operations of the filtering means, which primarily takes place by means of a countercurrent pulse of compressed air flowing into the filtering means.
