Menetelmä pakokaasujen puhdistamiseen käytettävän katalyytti-kennoston valmistamiseksi ja lujittamiseksi Tämä keksintö kohdistuu menetelmään pakokaasujen puhdistamiseen käytettävän katalyyttikennoston valmistamiseksi ja lujittamiseksi, jossa menetelmässä päällekkäin asetetuista poimutetusta ja suorasta folionauhasta muodostetaan pyörittämällä kierteinen kennosto.The present invention relates to a method for manufacturing and reinforcing a catalyst cell for exhaust gas purification, in which a helical cell is formed by rotating a superimposed corrugated and straight foil strip.

Tällainen kennosto tunnetaan ennestään mm. GB-patentista 2 069 364. Kyseisessä patentissa esitetyn menetelmän mukaisesti päällystämättömistä foiionauhoista valmistetaan ensin kennosto ja kennoston molempiin tai toiseen päähän hitsataan yksi tai useampia saumoja, joiden tarkoituksena on estää kierteisten folionauhojen aksiaalinen liikkuminen toistensa suhteen. Tässä menetelmässä kennosto voidaan pinnoittaa tu-kiainekerroksella ja katalyyttlaineella vasta hitsaamisen jälkeen, koska tukiaine alentaa sähkönjohtokykyä ja estää virran kulkua hitsaamisen aikana. Kun tukiaine levitetään valmiiseen kennostoon, se ei leviä tasaisesti, vaan kerääntyy folioiden yhtymäkohtien muodostamiin koloihin ja kerää itseensä varsinaista katalyyttisesti aktiivista ainetta, joten katalyyttisina ei tule tehokkaasti käytettyä, mikä puolestaan lisää kustannuksia ja heikentää tehoa.Such a honeycomb is already known e.g. GB Patent 2,069,364. According to the method disclosed in that patent, uncoated foil strips are first made into a honeycomb and one or more seams are welded to both or one end of the honeycomb to prevent axial movement of the helical foil strips relative to each other. In this method, the honeycomb can be coated with a support layer and a catalyst wave only after welding, because the support material lowers the electrical conductivity and prevents the flow of current during welding. When the support is applied to the finished honeycomb, it does not spread evenly, but accumulates in the cavities formed by the junctions of the foils and collects the actual catalytically active substance, so that it cannot be used effectively as a catalyst, which in turn increases costs and reduces efficiency.

DE-patentissa 2 924 592 on esitetty menetelmä katalyyttiken-noston valmistamiseksi, jossa päällystämätön poimutettu ja suora folionauha kiinnitetään toisiinsa juottamalla. Tämän menetelmän haittana on se, että juottamisen yhteydessä joudutaan käyttämään korkeita lämpötiloja, mikä saa aikaan rakenteen heikkenemistä ja pinnan huonontumista. Menetelmänä juottaminen on kallis toimenpide ja juottaminen rajoittaa kennos-tomateriaalien valintaa vain sellaisiin metalleihin, joita voidaan juottaa. Tuollaiset materiaalit eivät välttämättä ole 2 78161 parhaita katalyyttikennostojen materiaaleja. Tässäkin menetelmässä kennosto voidaan pinnoittaa tukiaineksrroksslla ja katalysoivilla aineilla vasta sen jälkeen, kun foliot on kiinnitetty toisiinsa.DE patent 2,924,592 discloses a process for the preparation of a catalyst composition in which an uncoated corrugated and a straight foil strip are attached to each other by soldering. The disadvantage of this method is that high temperatures have to be used during soldering, which causes deterioration of the structure and deterioration of the surface. As a method, soldering is an expensive operation and soldering limits the choice of honeycomb materials to only metals that can be soldered. Such materials may not be the 2 78161 best catalyst cell materials. Also in this method, the honeycomb can be coated with a support excipient and catalytic agents only after the foils have been attached to each other.

Suomalaisessa patenttihakemuksessa 861 801 on esitetty menetelmä katalyyttikennoston valmistamiseksi ja lujittamiseksi. Menetelmässä sekä tukiainekerroksella että katalyyttikerrok-sella etukäteen päällystetyt poimutettu ja suora folionauha kiinnitetään keskiakaeliin, joka on ohut tanko, ja jonka ympärille halutun kokoinen kennosto muodostetaan, minkä jälkeen akselin päihin kiinnitetään päätytuet siten, että ne painuvat hieman kennoston sisään estäen folioiden aksiaalisen liikkumisen. Tässä menetelmässä kennoston sisään jäävä keskiakseli tai -levy aiheuttaa lisäpainoa kennostoon ja lisäksi keskiak-seli päätytukineen pienentää hieman katalyyttikennoston poikkileikkauksen avointa alaa.Finnish patent application 861 801 discloses a method for manufacturing and strengthening a catalyst cell. In the process, a corrugated and straight foil strip pre-coated with both a support layer and a catalyst layer is attached to a central neck, which is a thin rod, around which a honeycomb of the desired size is formed, after which end supports are attached to the shaft ends. In this method, the central shaft or plate inside the cell causes additional weight to the cell and, in addition, the central shaft with its end supports slightly reduces the open area of the cross section of the catalyst cell.

Esillä olevan keksinnön tarkoituksena on saada aikaan menetelmä katalyyttikennoston valmistamiseksi ja lujittamiseksi, jolla menetelmällä ei ole ennestään tunnettujen menetelmien haittapuolia. Tämä aikaansaadaan keksinnön mukaisesti siten, että kierretään tukiainekerroksella ja katalyyttikerroksella etukäteen pinnoitettuja suoraa ja poimutettua folionauhaa tietyn kokoisen akselin ympärille siten, että akselin poistamisen jälkeen kennoston keskelle jää halutun kokoinen pitkittäinen aukko. Tämän jälkeen kennosto painetaan ovaaliksi, eli kennoston poikkileikkaus on ns. “race track" eli ajoradan muotoinen ja kennoston keskellä ollut aukko umpeutuu. Tämän jälkeen kennoston läpi painetaan tai ammutaan tuki, joka estää kennoston purkautumisen ja folionauhojen keskinäisen hankautumisen toisiaan vastaan ja näin syntyy muotonsa säilyttävä jäykkä kappale.The object of the present invention is to provide a method for manufacturing and reinforcing a catalyst cell, which method does not have the disadvantages of the previously known methods. This is achieved according to the invention by winding a straight and corrugated foil strip pre-coated with a support layer and a catalyst layer around a shaft of a certain size, so that after removing the shaft, a longitudinal opening of the desired size remains in the middle of the honeycomb. After this, the honeycomb is pressed oval, ie the cross section of the honeycomb is the so-called The "race track", which is shaped like a carriageway and is in the middle of the honeycomb, closes. A support is then pressed or fired through the honeycomb to prevent the honeycomb from unraveling and the foil strips from rubbing against each other.

Keksinnön oleelliset tunnusmerkit on esitetty oheisissa patenttivaatimuksissa .The essential features of the invention are set out in the appended claims.

Keksinnön erään suoritusmuodon mukaisesti on mahdollista aikaansaada katalyyttikennosto siten, että kierretään etukäteen pinnoitetut suora ja poimutettu folionauha suoraan pyöreäksi kennostoksi siten, että kennon keskiosaan ei jää pitkittäistä aukkoa. Tämän jälkeen kennoston läpi painetaan tai ammutaan tuki, joka estää kennoston purkautumisen tai folionauhojen keskinäisen hankautumisen toisiaan vasten ja näin syntyy muotonsa säilyttävä jäykkä kappale.According to an embodiment of the invention, it is possible to provide a catalyst cell by twisting the pre-coated straight and corrugated foil strips directly into a round cell so that no longitudinal opening remains in the central part of the cell. A support is then pressed or fired through the honeycomb, which prevents the honeycomb from discharging or the foil strips from rubbing against each other, thus creating a rigid body that retains its shape.

Keksinnön erään suoritusmuodon mukaisesti kennon lävitse painetaan kaksi tai useampia tukia siten, että tuet ovat joko rinnakkain tai peräkkäin toisiinsa nähden.According to an embodiment of the invention, two or more supports are pressed through the cell so that the supports are either parallel or successive to each other.

Tukien läpivienti kennoston lävitse voidaan suorittaa joko painamalla tai ampumalla. Keksinnön erään suoritusmuodon mukaisesti on mahdollista, että tukia varten tehdään kennostoon tuen mittainen reikä etukäteen esimerkiksi poraamalla ja reiän tekemisen jälkeen siihen painetaan reiän täyttävä tuki.The passage of the supports through the honeycomb can be done either by pressing or by shooting. According to an embodiment of the invention, it is possible for the supports to be provided with a hole the length of the support in the honeycomb in advance, for example by drilling, and after making the hole, a support filling the hole is pressed into it.

Kennoston läpi painettava tuki on edullisesti poikkileikkaukseltaan pyöreä, soikea, neliö tai suorakaiteen muotoinen. Keksinnön mukaisesti kennoston läpi viety tuki on pituudeltaan kennoston halkaisijan (pyöreä kenno) tai kennoston korkeuden (race track) mittainen ja edullisesti 1-10 mm kennos-ton halkaisijaa tai korkeutta pidempi.The support to be pressed through the honeycomb is preferably round, oval, square or rectangular in cross section. According to the invention, the support passed through the honeycomb has a length equal to the diameter of the honeycomb (round cell) or the height of the honeycomb (race track) and preferably 1 to 10 mm longer than the diameter or height of the honeycomb.

Kennoston läpi viety tuki tai tuet on edullisesti valmistettu tulenkestävästä teräksestä.The support or supports passed through the honeycomb are preferably made of refractory steel.

Mikäli pyöreä kennosto muodostetaan siten, että etukäteen tu-kiainekerroksella ja katalyyttikerroksella pinnoitetut suora ja poimutettu metallifolio kiinnitetään keskiakseliin, joka on 4 78161 ohut tanko tai levystä U-muotoon taivutettu aihio, ja jonka ympärille halutun kokoinen pyöreä kennoeto muodostetaan, pyö-rityaakaelina käytetty keskiakeeli jätetään kennoeton sisään. Keskiakseliin on ennen kennoeton pyörittämistä tehty yksi tai useampia aukkoja siten, että kennoeton pyörittämisen jälkeen kennoeton lävitse painetaan tai ammutaan tuki siten, että se kulkee keskiakselissa olevan aukon tai aukkojen lävitse. Näin syntyy muotonsa säilyttävä jäykkä katalyyttikennosto.If the circular honeycomb is formed by attaching a straight and corrugated metal foil pre-coated with a support layer and a catalyst layer to a central shaft which is a 4 78161 thin rod or a blank bent from a sheet into a U-shape, around which a round cell support of the desired size is formed, inside the cell. One or more openings are made in the central shaft before the cell support is rotated, so that after the cell support is rotated, a support is pressed or fired through the cell support so that it passes through the opening or openings in the central shaft. This creates a rigid catalyst cell that retains its shape.
