Description: M A SYSTEM AND A PROCESS FOR THE PURIFICATION TREATMENT OF SMOKES, DUSTS AND EXHAUST GASES AFTER COMBUSTION" The present invention concerns a system t o realizing a 5 process for the purification treatment of smokes, dusts and exhaust cases after combustion, consisting of suction means and water-nebuliring nozzles, for the transformation of said smokes, dusts and gases firstly into smog and then in¬ to sewage. 0 The object of the present invention may be applied to all devices characterized in the emission of smokes, dusts and exhaust gases like: smokestacks, flues of heating systems, industrial exhaust chimneys and the exhaust-pipes for eom- & bustion gases of endothermic motor vehicles. The problem of air pollution, with the following stagnation of the smog and the falling down of acid rsins, actually shows an increase proportional to industrialization, and the essays of elimination of the polluting elements are not sufficient for the protection of health of people and natu¬ re. It is the aim of the present invention to reduce above said damages for the health and for nature by the treatment and the purification of smokes, dusts and exhaust gases before these are led into the atmosphere, by the reduction of the polluting agents into sewage, that in turn may be treated in a well-known manner. The aim set forth may be reached according to the present invention by means of a system comprising a hood or a cone, provided above the smokestacks, the industrial chimneys, the flues and nearby the βxhauβt-pipeβ , for leading smokes, dusts and gases, by means of a suction fan, into a serpen¬ tine duct provided with a series of nozzles for the nebuli- zation of water under pressure co ing from a pump or a com¬ pressor, that will reduce the pollution firstly into smog and then into sewage, while the purified air and/or vapour get out through a fil er-grate. Said sewage will be led, by means of an appropriate con- veyyor and duct, into decantation basins, and filtered for being re-used or discharged into the drains. The object of the present invention will be described more in detail hereinbeloz according to the e closed drawings, lκ which t u preferred embodiments are shown. Figure 1 shows a vertical section and a section along A-A of the system for the realization of the purifi¬ cation process of smokes coming out of smoke¬ stacks, industrial chimneys and flues for dome¬ stic heating systems, placed inside a metal tower. Figure 2 shows vertical sections A-A and B-B and the hori¬ zontal section C-C of a variant of the system for the treatment of the exhaust gases of combustion vehicles, placed in a container provided in the luggage van of the vehicles, and that will aspire the exhaust gases and emit purified air or va¬ pour. The system for the realization of the purification process according to figure 1 comprises the following means: - a wind vane 1 - a cover 2 of the system - a protection and maintenance plane 3 - a suction fan . (variable) - a cap 5 for the collection of the smokes - a movable screen 6 for the protection from the wind - a structure 7 (smokestack) - a duct 8 for the smoke - a metal structure 9 for the support of the system - a plurality of tubes 10 for the treatment of the smokes - a plurality of nozzles or nebulizer injectors 11 - an air duct 12 for performing the nebulization - a duct 13 for the water to be nebulized - an air compressor 14 - a sewage conveyor 15 - an outlet 16 for purified air or vapour - a plurality of basins 17 for the decantation of the se¬ wage - a ladder 20 for allowing the access to the system - a floor-grate 21 for maintenance. For what concerns the variant of the .system for the treat¬ ment of the exhaust gases of combustion-motor vehicles, as shown in figure 2, the following means are comprised: - a replaceable filter 31, - a water-tank 32, - a tank 33 for the storage of the sewage, - an outlet 34 for the discharge of the sewage, - a tube 35 for the discharge of the sewage, - a duct 36 with nozzles for the emission of air from the compressor, - a duet 37 for bringing the water to the nebulizing nozz¬ les , - a serpentine duct 38 for the smoke treatment area, - a compressor 39 for providing the pressure to the nebuli- zers, - an aspiration fan 40 at variable speed, - a tube 41 for connecting the exhaust-pipe to the purifi¬ cation systea - a tube 42 for the re-cycling of the water, - a tap 43 for the discharge of the sewage, - a sewage conveyor 44, - a tube 45 for the outlet of purified air or vapour, - a pplug 46 for the loading of the tank, with bleed 47, - an electrovalve 48 for stopping the water flow to the ne bulizers, - a gasket 49 for the plug of the filters, - a device 50 for blocking the filters, - a filter 51 with metal rings in oil bath, provided at th - a- struetur*.52.-for- -th-e- .ρr.ote t.io.1 -o.f- .th»..co.nnec.t-io.n..b--t^- ween the exhaust-pipe and the cone of the system. In said latter variant of the system according to the pre- sent invention the energy for the working of the fan 40 and of the compressor will be obtained from the accumulator battery or from the current generator of the vehicle, by means of the passage through the accelerator. The advantages obtained by means of the purification system and process according to the present invention, are the followin i - reduction of the air pollution} - lowering of elimination of the smog-effect, that in dβ- termined periods stagnates above urban centres, causing problems to the health of peoples - reduction or elimination of the causes of deterioration of monuments in urban centres.
