Description

Foreliggende oppfinnelse vedrører et avgassfilter for en forbrenningsmotor, hvor filterets hus er forbundet med en forbrenningsmotors avgassrør og inneholder etter hverandre anordnede, dreibare, liggende sylindere, hvis mantelflate er utformet som filterflate og hvis nedre del er dyppet ned i en væske, idet avgassene føres gjennom filteret på en sådan måte at de tvinges til å strømme gjennom filterflåtene. The present invention relates to an exhaust gas filter for an internal combustion engine, where the filter's housing is connected to an internal combustion engine's exhaust pipe and contains successively arranged, rotatable, horizontal cylinders, the outer surface of which is designed as a filter surface and the lower part of which is immersed in a liquid, the exhaust gases being passed through the filter in such a way that they are forced to flow through the filter floats.

For tiden er luftforurensningsproblemet blitt et bren-nende aktuelt spørsmål i den utviklede verden. Hovedårsaken til forurensningene er den stadig tiltagende industrialiseringsgrad i samfundet og trafikken som har antatt store proporsjoner. Currently, the problem of air pollution has become a burning topical issue in the developed world. The main reason for the pollution is the ever-increasing degree of industrialization in society and traffic, which has assumed large proportions.

De stoffer som forurenser luften, er utallige og likeledes kil-dene som produserer disse stoffer. Til de verste luftforuren-sere hører forbrenningsmotorene. Mange typer av anordninger er blitt utviklet for rensing av avgasser, men hittil har denslags anordninger enten vært for kostbare eller ved lav pris hatt temmelig dårlig virkningsgrad. The substances that pollute the air are countless and so are the sources that produce these substances. Combustion engines belong to the worst air polluters. Many types of devices have been developed for cleaning exhaust gases, but until now such devices have either been too expensive or, at a low price, have had a rather poor degree of efficiency.

Formålet med oppfinnelsen er å skaffe et avgassfilter som er bedre enn tidligere kjente anordninger, og dette oppnås ifølge oppfinnelsen ved at hver filtersylinder har et eget, særskilt væskerom. Derved oppnås at der kan anvendes forskjellige væsker i de forskjellige væskerom. I avgassenes strømningsret-ning må f.eks. væsken i det første rom kunne tåle betydelig høy-ere temperatur enn væskene i de etterfølgende rom. Ifølge oppfinnelsen er det mulig å anvende en væske av bedre kvalitet i det første rom enn i de etterfølgende. På den annen side blir væsken i det første rom hurtigere nedsmusset enn i de øv-rige, hvorfor man vil velge å skifte væsken bare i det første rom. Dette betyr en betydelig besparelse, idet det ikke er nødvendig å skifte ut hele væskemengden. The purpose of the invention is to provide an exhaust gas filter that is better than previously known devices, and this is achieved according to the invention by each filter cylinder having its own, separate liquid chamber. Thereby it is achieved that different liquids can be used in the different liquid compartments. In the direction of flow of the exhaust gases, e.g. the liquid in the first chamber could withstand a significantly higher temperature than the liquids in the subsequent chambers. According to the invention, it is possible to use a liquid of better quality in the first chamber than in the subsequent ones. On the other hand, the fluid in the first chamber gets dirty faster than in the other chambers, which is why you will choose to change the fluid only in the first chamber. This means a significant saving, as it is not necessary to replace the entire amount of liquid.

Oppfinnelsen vil fremgå nærmere av den følgende beskri-velse under henvisning til tegningen, hvis fig. 1 viser et fil-ter ifølge oppfinnelsen i lengdesnitt og fig. 2 viser et snitt etter linjen II - II på fig. 1. The invention will appear in more detail from the following description with reference to the drawing, whose fig. 1 shows a filter according to the invention in longitudinal section and fig. 2 shows a section along the line II - II in fig. 1.

På fig. 1 og 2 betegner 1 et filterhus, i hvilket der er anbragt to sylindere 3. Avgassrøret er betegnet med 2 og er forbundet med huset 1. Sylindrene 3 har en felles aksel 4 og på deres perforerte mantler 17 er der festet et filtermateriale 5, "f.eks. mineralull. Sylindrenes 3 respektive væskerom er betegnet med 6 og 7. Ved utførelsen ifølge fig. 1 driver en motor 8 sylindrenes felles aksel 4 over en kobling 9. Et lager 10 er an-ordnet for et rør 18 som omgir en kanal 15 og til hvis ender sylindrenes endevegger 19 er festet. Lageret 10 er på sin side forbundet med endeveggen 21 av en indre kapsel eller hylse 20 Som omgir den bakre sylinder 3. Husets 1 endevegg 11 er ved h-jelp av et bånd 12 og en tetning 13 festet til selve huset 1. Når endeskiven 11 er løsnet etter at båndet 12 er blitt fjernet, kan sylindrene 3 tas ut ved at mutteren 14 løses. De fra av-<g>assrøret 2 kommende gasser passerer gjennom den første roteren-de sylinders 3 perforerte mantel, gjennom filtermaterialet 5 og inn i sylinderen og derfra gjennom kanalen 15 som forbinder sylindrene, inn i den annen sylinder 3 og forlater denne etter å ha passert gjennom filtermaterialet 5, den perforerte sylinder-mantel og videre i renset tilstand ut i atmosfæren gjennom en åpning 16 i husets 1 endeplate 11. In fig. 1 and 2, 1 denotes a filter housing, in which two cylinders 3 are placed. The exhaust pipe is denoted by 2 and is connected to the housing 1. The cylinders 3 have a common shaft 4 and on their perforated mantles 17 a filter material 5 is attached, " e.g. mineral wool. The respective liquid spaces of the cylinders 3 are denoted by 6 and 7. In the embodiment according to Fig. 1, a motor 8 drives the cylinders' common shaft 4 via a coupling 9. A bearing 10 is arranged for a tube 18 which surrounds a channel 15 and to whose ends the end walls 19 of the cylinders are attached. The bearing 10 is in turn connected to the end wall 21 by an inner capsule or sleeve 20 which surrounds the rear cylinder 3. The end wall 11 of the housing 1 is by h-jelp of a band 12 and a seal 13 attached to the housing itself 1. When the end disc 11 has been loosened after the band 12 has been removed, the cylinders 3 can be taken out by loosening the nut 14. The gases coming from the exhaust pipe 2 pass through the first rotor- the cylinder's 3 perforated mantle, through the filter material 5 and into the cyl inside and from there through the channel 15 which connects the cylinders, into the other cylinder 3 and leaves this after passing through the filter material 5, the perforated cylinder jacket and further in a purified state into the atmosphere through an opening 16 in the housing 1 end plate 11.

Utførelsen kan variere innenfor oppfinnelsens ramme. Således kan f.eks. sylindrene 3 være festet til adskilte aksler, særlig hvis man vil gi dem forskjellig omdreiningshastighet. Rotasjonsbevegelsen kan også tilføres sylindrene 3 fra en annen kilde enn motoren 8. Man kan således la avgasstrømmen fra røret 2 drive en særskilt propell, hvis aksel er forbundet med akselen The execution may vary within the scope of the invention. Thus, e.g. the cylinders 3 be attached to separate shafts, especially if you want to give them different rotational speeds. The rotational movement can also be supplied to the cylinders 3 from a source other than the engine 8. One can thus allow the exhaust gas flow from the pipe 2 to drive a separate propeller, the shaft of which is connected to the shaft

4 for sylindrene 3 som derved vil få sin rotasjonsbevegelsé fra "propellen. Videre kan sylindrenes rotasjonsbevegelsé tas fra bevegelige deler i forbrenningsmotoren over overføringsorganer. Som filtermateriale 5 kan der anvendes forskjellige stoffer av-hengig av hvilke forurensninger man ønsker å fjerne fra avgassene. Det samme gjelder når det er tale om varieringsmulighe-tene for væskene som benyttes i væskeromirene 6 og 7. Gassenes strømningsvei kan også varieres. Man kan f.eks. lede gassene inn i den første sylinder 3 gjennom dennes perforerte endeflate og deretter ut gjennom filtermaterialet 5 og den perforerte mantel 17 og videre til den neste sylinder. Det er innlysende at et avgassfilter ifølge oppfinnelsen kan benyttes like godt i for-bindelse med stasjonære som med mobile forbrenningsmotorer. 4 for the cylinders 3, which will thereby get their rotational movement from the propeller. Furthermore, the cylinders' rotational movement can be taken from moving parts in the internal combustion engine via transmission means. Different substances can be used as filter material 5, depending on which pollutants you want to remove from the exhaust gases. The same applies when it comes to the variation possibilities for the liquids used in the liquid chambers 6 and 7. The flow path of the gases can also be varied. You can, for example, lead the gases into the first cylinder 3 through its perforated end surface and then out through the filter material 5 and the perforated mantle 17 and on to the next cylinder.It is obvious that an exhaust gas filter according to the invention can be used just as well in connection with stationary as with mobile internal combustion engines.
