Abstract
Description
20 25 30 ' 529 721 Ett optimalt filter skall ha ett högt korrosionsmotstånd och oxidationsmotstånd, ha hög mekanisk styrka samt ha ett högt termochockmotstànd och kunna tillverkas som ett monolitiskt filter. 20 25 30 '529 721 An optimal filter must have a high corrosion resistance and oxidation resistance, have a high mechanical strength and have a high thermal shock resistance and can be manufactured as a monolithic filter.
Ett filter enligt föreliggande uppfinning tillmötesgår dessa krav.A filter according to the present invention meets these requirements.
Föreliggande uppfinning hänför sig således till ett filter för att avskilja partiklar från gaser och vätskor, vilket har en öppen porositet, och utmärkes av, att filtret är tillver- kat av ett pulverformigt material innefattande materialet MWHAQQ, där M är åtminstone ett material valt ur gruppen ti- tan, vanadin, krom, zirkonium, niob och tantal, där A är åt- minstone ett material valt ur gruppen aluminium, kisel, ger- manium och där X är åtminstone ett material valt ur gruppen kol och/eller kväve, av att materialens ingående del i det totala materialet är givet av n och z, där n ligger i inter- vallet 0.8 - 3.2 och där z ligger i intervallet 0.8 - 1.2.The present invention thus relates to a filter for separating particles from gases and liquids, which has an open porosity, and is characterized in that the filter is made of a powdered material comprising the material MWHAQQ, where M is at least one material selected from the group titanium, vanadium, chromium, zirconium, niobium and tantalum, where A is at least one material selected from the group of aluminum, silicon, germanium and where X is at least one material selected from the group of carbon and / or nitrogen, by the constituent part of the materials in the total material is given by n and z, where n is in the range 0.8 - 3.2 and where z is in the range 0.8 - 1.2.
Nedan beskrives föreliggande uppfinning närmare, delvis i samband med olika exemplifierande utföringsexempel av uppfin- ningen.The present invention is described in more detail below, in part in connection with various exemplary embodiments of the invention.
Filtret enligt uppfinningen är särskilt lämpat för avskilj- ning av partiklar från varma rökgaser som är oxiderande och korrosiva.The filter according to the invention is particularly suitable for separating particles from hot flue gases which are oxidizing and corrosive.
Föreliggande filter är anordnat att avskilja partiklar från gaser och vätskor. Filtret har en öppen porositet och är monolitiskt.The present filter is arranged to separate particles from gases and liquids. The filter has an open porosity and is monolithic.
Hmnwpxwnmmmmgmamw, mmßæ44 10 75 25 30 529 721 Enligt uppfinningen är filtret tillverkat av ett pulverfor- migt material innefattande titan och kol samt ett av materia- len kisel och aluminium.According to the invention, the filter is made of a powdered material comprising titanium and carbon as well as one of the materials silicon and aluminum.
Vid tillverkningen formas filtret, varefter det sintras vid lämplig temperatur i beroende av materialets sammansättning.During manufacture, the filter is formed, after which it is sintered at a suitable temperature depending on the composition of the material.
Utav materialet MmHA,Xn är två material mycket föredragna för föreliggande filter, nämligen att filtret innehåller materia- let Ti3SiC2 eller att filtret innehåller materialet Ti2AlC.Out of the material MmHA, Xn, two materials are very preferred for the present filter, namely that the filter contains the material Ti3SiC2 or that the filter contains the material Ti2AlC.
Båda dessa material ger filtret högt termochockmotstând och mekanisk styrka, vilket gör det möjligt att tillverka ett monolitiskt filter och därmed kunna hålla produktionskostna- derna låga, samtidigt som korrosionsmotstàndet visat sig vara mycket gott.Both of these materials give the filter high thermal shock resistance and mechanical strength, which makes it possible to manufacture a monolithic filter and thus be able to keep production costs low, while the corrosion resistance proved to be very good.
Korrosionsmotståndet, d.v.s. motståndet mot nedbrytning av oxider, för materialet Ti3SiC2är gott för temperaturer i var- je fall upp till l000°C, eftersom ett skyddande oxidskikt av SiO2 / TiO2bildas på ytan.The corrosion resistance, i.e. the resistance to decomposition of oxides, for the material Ti3SiC2 is good for temperatures in any case up to 1000 ° C, since a protective oxide layer of SiO2 / TiO2 is formed on the surface.
Korrosionsmotståndet för materialet Ti2AlC vid hög temperatur beror på att Alfib bildas på materialets yta, vilket är en stabil oxid. Aluminiumoxiden är mycket stabil vid höga tempe- raturer. Därför har materialet Ti2AlC ett mycket gott korro- sionsmotstånd i varje fall vid temperaturer upp till l400°C.The corrosion resistance of the material Ti2AlC at high temperature is due to the formation of Al fi b on the surface of the material, which is a stable oxide. The alumina is very stable at high temperatures. Therefore, the material Ti2AlC has a very good corrosion resistance in any case at temperatures up to 140 ° C.
Oxidationsmotståndet vid hög temperatur, såsom l000°C, är bättre hos Ti2AlC än Ti3SiC2. Materialet har gott oxidations- motstånd ända upp till l400°C i oxiderande miljö.The high temperature oxidation resistance, such as 1000 ° C, is better in Ti2AlC than Ti3SiC2. The material has good oxidation resistance all the way up to 140 ° C in an oxidizing environment.
H:\DOCWORK\Ansökningstcxt.doc , 2006-03-14 10 15 20 25 529 721 Materialet Ti3SiC2har ett gott oxidationsmotstánd upp till omkring l0O0°C i oxiderande miljö.H: \ DOCWORK \ Ansökstcxt.doc, 2006-03-14 10 15 20 25 529 721 The material Ti3SiC2 has a good oxidation resistance up to about 10 ° C in an oxidizing environment.
Vid vissa tillämpningar för filter, såsom för filter för re- ning av rökgaser, krävs att filtret kan regenereras. Detta innebär att filtret utsätts för en högre temperatur än vid normal filtrerande drift. Exempelvis kan beroende på tillämp- ning en regenereringstemperatur vara upp till eller något överstigande lO00°C.In certain applications for filters, such as for filters for purification of flue gases, it is required that the filter can be regenerated. This means that the filter is exposed to a higher temperature than during normal filtering operation. For example, depending on the application, a regeneration temperature may be up to or slightly in excess of 100 ° C.
De explicit angivna två materialen klarar denna temperatur, varför de är lämpliga även för filter som regenereras.The explicitly stated two materials can withstand this temperature, which is why they are also suitable for filters that are regenerated.
Detsamma gäller filter som innehåller materialet(TiL*Nbg2AlC.The same applies to filters that contain the material (TiL * Nbg2AlC.
X ligger föredraget i intervallet 0.05 - 0.5.X is preferably in the range 0.05 - 0.5.
Ovan har ett antal utföringsformer av materialet MnuAqXnangi~ vits. Emellertid är det uppfinnarnas uppfattning att även andra material NßHAgXnän de tre ovan explicit nämnda materia- len uppvisar goda egenskaper avseende korrosionsmotstànd, oxidationsmotstànd, termochockmotstànd och mekanisk styrka.Above, a number of embodiments of the material MnuAqXnangi ~ vits. However, it is the opinion of the inventors that other materials, including the three materials explicitly mentioned above, also exhibit good properties with respect to corrosion resistance, oxidation resistance, thermochock resistance and mechanical strength.
Detta gör att även de kan användas för att framställa ett monolitiskt filter avsett att arbeta vid temperaturer upp till åtminstone lO00°C.This means that they too can be used to produce a monolithic filter intended to operate at temperatures up to at least 100 ° C.
Föreliggande uppfinning skall därför inte anses begränsad till de tre ovan angivna materialen, utan kan varieras inom dess av bifogade patentkrav angivna ram.The present invention should therefore not be construed as limited to the three materials set forth above, but may be varied within the scope of the appended claims.
