Abstract

Filter til partikelrensning af urenheder I gasstrømme skal være kompakte og til lige være så effektive som muligt, herunder have et så lille trykfald som muligt. Sådanne filtre er ifølge opfindelsen opbygget af tre ringformede og plisserede filterelementer, omfattende et yderste (4), et mellemste (5) og et inderste filter element (6), hvilke filtre er sammenholdt ved filterets tilgangs- (1,12) og afgangs side (9,10). Herved kan der tilledes gas til såvel filterets ydre (7) og til mellemrummene (8) mellem inderste (6) og mellemste (5) filterelement, hvilken gas vil udledes (14) fra såvel det centrale filterkammer (15) og fra kammeret (17) mellem mellemste (5) og yderste filterelement (4).

Claims (7)

1. Filter til fjernelse af partikler fra gasstrømme, såsom fra luft, røg og restgasser, hvilket filter er udformet som et såkaldt kassettefilter, hvori filterelementer forløber mellem filterets tilgangs- og afgangsside, kendetegnet ved, at filterelementet omfatter et ringformet, inderste filter (6), som danner et centralt filterkammer (15), et uden om dette filter (6) yderligere ringformet, mellemste filter (5) samt et uden om dette filter (5) for-løbende yderste, ringformet filter (4), hvilke filtre (6,5,4) er fastholdt ved hhv. filterets tilgangs- (1,12) og afgangsside (9,10).
2. Filter ifølge krav 1, kendetegnet ved, at det yderste (4) og det inderste filter (6) forløber skråt udefter fra tilgangs- til afgangssiden, medens det mellemste filter (5) forløber skråt indefter fra tilgangs- til afgangssiden.
3. Filter ifølge krav 1 og 2, kendetegnet ved, at det yderste (4) og det mellemste filter (5) er sammenholdt ved tilgangssiden til dannelse af en ringformet ende (1), medens det inderste filter (6) er sammenholdt omkring midten af tilgangssiden i form af et cirkulært lukke (12), og at det yderste filter (4) ved afgangssiden er sammenholdt til dannelse af en ydre kant (9), medens det mellemste (5) og det inderste (6) er sammenholdt i en ringformet part (10), som udgør det centrale filterkammers (15) ende.
4. Filter ifølge krav 1-3, kendetegnet ved, at de enkelte filtre (4,5,6) er plisserede i hele deres udstrækning, længde og omkreds mellem deres tilgangs- og afgangsside.
5. Filter ifølge ethvert af kravene 1-4, kendetegnet ved, at der er udformet åbninger (13) langs det yderste filters (4) underside på afgangssiden, hvilke åbninger er dannet ved fjernelse af eller undladelse af klæbemiddel mellem plisseringerne langs underkanten (9).
6. Filter ifølge ethvert af kravene 1-5, kendetegnet ved, at tilgangssiden har cirkulær udstrækning (1), medens afgangssiden har firkantet udstrækning (9).
7. Anvendelse af det i krav 1-6 omhandlede filter, kendetegnet ved, at gassen (7,8), som skal filtreres, tilledes dels det kileformede kammer (16) mellem mellemste (5) og inderste filter (6), dels kammeret (3) uden for det yderste filter (4), hvorefter luften passerer dels det mellemste (5) og det inderste filter (6) og ledes ud (14,11) hhv. via det centrale filterkammer (15) og via det yderste kammer (17).
