Příklady provedení vvnálezuDETAILED DESCRIPTION OF THE INVENTION

Zařízení na čištění plynu .podle obrázku 1 přichází v podstatě v úvahu pro použití, u kterých je tlak na straně znečištěného plynu menší než na straně čistého plynu (naor. skládkové plyny). Zařízeni podle obrázku 3 je nasazeno přednostně při tlacích, které jsou na straně znečištěného plynu větší než na straně čistého plynu (např. dieselového vozidla). Pro těžké čisticí problémy muže být účelné zapojit za sebcu více filtračních modulů 9 (obrázek 4).The gas scrubber according to Figure 1 is suitable for applications in which the pressure on the polluted gas side is less than on the clean gas side (or landfill gases). The device of Figure 3 is preferably used at pressures that are larger on the polluted gas side than on the clean gas side (eg a diesel vehicle). For severe cleaning problems, it may be expedient to connect more filter modules 9 (Figure 4).

V tělese se vstupem 1_ čistého plynu je uspořádán z nosíce 2 izolujícího vyhř i vatě 1 né z porézního, materiálu.. Na kovové oletivo hosicového materiálu a/nebo opatřen katalyticky účinnou Katalyticky účinná vrstva může sestávat □ šlecht i 1ých kovů .In the body with a clean gas inlet 7, it is arranged from a wearer 2 insulating heater 1 made of porous material. On a metal lining of the hosepipe material and / or provided with a catalytically active catalytically active layer may consist of noble metals.

znečištěného plynu a výstupem 1_0 filtrační modul 9, který sestává tepelně odolného a elektricky nosiči’ 2 je uspořádané 3. Vnitřní povrch porézního kovového pletiva 3 může být (není znázorněna ) . z oxidů kovů nebo z vrstvouand the outlet 10 of the filter module 9, which consists of a heat resistant and electrically supported carrier 2, is arranged 3. The inner surface of the porous metal mesh 3 may be (not shown). of metal oxides or of a layer

Znečištěný plyn, který obsahuje znečištěné a αχ idovatelné látky, dorazí pres vstup I znečištěného plynu do pouzdra Ί1 lobrázek 3), nebo přímo do dutého prostoru porézního nosiče 2 (obrázek 1). Z pouzdra 11 proudí znečištěný plyn skrz po .případě vyhřívatelné kovové pletivo 3 a nosič 2 do dutého prostoru nosiče 2. a odtud k výstuDu 10 čistého plynu. Oospěje-li znečištěný plyn od vstuou 1 znečištěného plynu přímo do dutého prostoru nosiče 2., proudí odtud skrz nosič 2 a kovové pletivo 3 do pouzdra i i a k výstuou 10. čistého plynu. Při průchodu skrz porézní nosič 2 a kovové pletivo 3 je dosaženo mezi oxi dováté 1nými látkami znečištěného plynu a po případe katalyticky naneseným vnitřním povrchem porézního nosiče 2 a/nebo kovového pletiva 3 vzájemného půšďbení. Jsou-li 'navrženy katalytické vrstvy, je dosaženo samoudržite1 né nízkoteplotní oxidace při * 300’ vnitřním povrchem porézního nosiče 2 a/nebo kovového pletiva 3 vzájemného působeni, Jsou-li navrženy katalytické vrstvy, je dosaženo samo udržitelné nízkoteolotni oxidace při a 3 0 0 : (bezplamenné spalování). Při sazemi zatíženém .znečistěném plynu je možné e/otermické spalováni sazí . Energie, vzniklá oxidací škodlivých látek v znečištěném plynu,· může být tep 1ctechnicky využita. Tato provozní teplota (požadovaná teplota) zařízeni na čištěni plynu může být zjištěna teplotním čidlem 7. Hodnota, naměřená teplotním čidlem 7_, může být využita pro regulaci energetického přívodu 5 pro v vyhřívání kovového pletiva 3. Regulací jsou vyloučeny teplotní skoky nebo lokální teplotní zvýšení. Rozdílným složením znečistěného plynu způsobený- teplotní přebytek nebo nedostatek, (deficit) tím může býi vyregulován. Přídavně ionizační zařízení 8 s elektrodami 4, 5. .umožňuje dopravu např. těžko odbouráte 1ných polymerů ve znečištěném plynu k teplým kovovým pletivům 3 a nosiči 2. nebo vytvoření ozonu.The polluted gas containing contaminated and αχ identifiable substances arrives via the polluted gas inlet I into the housing do1 of the Figures 3) or directly into the hollow space of the porous support 2 (Figure 1). From the housing 11, the contaminated gas flows through the possibly heatable metal mesh 3 and the carrier 2 into the cavity of the carrier 2 and from there to the clean gas outlet 10. If the polluted gas enters from the polluted gas inlet 1 directly into the hollow space of the carrier 2, it flows from there through the carrier 2 and the metal mesh 3 into the housing and through the clean gas outlet 10. As it passes through the porous support 2 and the metal mesh 3, contaminated gas is achieved between the oxidized substances and, if necessary, the catalytically deposited inner surface of the porous support 2 and / or the metal mesh 3 with each other. When catalytic layers are designed, a self-sustaining low temperature oxidation is achieved at 300 ° by the inner surface of the porous support 2 and / or metal mesh 3 interacting. : (flameless combustion). With soot loaded contaminated gas, it is possible to burn the soot. The energy generated by the oxidation of harmful substances in the polluted gas can be used technically. The operating temperature (set temperature) a gas cleaning device can be detected by the seventh temperature sensor value measured by the temperature sensor 7, it can be used for controlling power supply 5 for heating the metal mesh 3. Regulation of temperature jumps are eliminated or the local temperature increase. The temperature surplus or deficiency caused by the different composition of the polluted gas (deficit) can thus be regulated. In addition, the ionisation device 8 with the electrodes 4, 5 allows the transport of e.g. hardly degraded polymers in the polluted gas to the hot metal tissues 3 and carrier 2 or the formation of ozone.

Radiální uspořádání zařízení na čištění, plynu umožňuje homogenní oblast působení kovových pletiv 3 a porézního nosiče 2. Kaskádovité uspořádání (obrázek 4) více filtračních modulů 9 po případě s rozdílně působícím j katalytickým povlakem je možné bez významné ztráty tlaku, takže se tímto způsobem, nechají škodlivé látky selektivně v optimálně vyfiltrovat. 12 naznačuje uvolňovací . prostor pro plyn.The radial arrangement of the gas scrubber allows a homogeneous area of action of the metal tissues 3 and the porous support 2. A cascade arrangement (Figure 4) of multiple filter modules 9 after a case with a differently acting catalytic coating is possible without significant pressure loss, so selectively filter out harmful substances. 12 indicates a release. space for gas.

Na základě modulového uspořádání se hodí zařízení na čištění plynu k vybaveni stávajících zařízeni. Odbourání i .Due to the modular arrangement, the gas scrubber is suitable for retrofitting existing plants. Degradation i.
