Description
Foreliggende oppfinnelse vedrører et absorpsjonsmateriale for en filteranordning av den type som er angitt;i patentkravets ingress. Sugeanordninger brukes i alminnelighet i anlegg hvor problemgasser dannes, og disse anordninger inneholder et filter for å oppsamle brestanddeler som ikke skal slippes ut i omgivelsene utenfor disse anlegg. The present invention relates to an absorption material for a filter device of the type indicated in the preamble of the patent claim. Suction devices are generally used in facilities where problem gases are formed, and these devices contain a filter to collect glacial constituents that are not to be released into the environment outside these facilities.
Filtere for å oppsamle problematiske bestanddeler i gassene er også anordnet foran utløpsåpningene for materialer som avgir problematiske gasser. Karbonpartikler er hittil brukt for å tilveiebringe slikt absorpsjonsmateriale. Det er i praksis funnet at slike filtere med karbonpartikler ikke er effektive nok til å fjerne væskepartikler fra strømmende gassmedier. Filters to collect problematic components in the gases are also arranged in front of the outlet openings for materials that emit problematic gases. Carbon particles have hitherto been used to provide such absorption material. It has been found in practice that such filters with carbon particles are not effective enough to remove liquid particles from flowing gas media.
Formålet med foreliggenede oppfinnlse er å effektivt ta vare på væskepartikler i strømmende gassmedier. Dette oppnås ved å bruke ett eller flere legemer av den art som er angitt i patentkravets karakteriserende del. ' The purpose of the present invention is to effectively take care of liquid particles in flowing gas media. This is achieved by using one or more bodies of the type specified in the characterizing part of the patent claim. '
Et filter kan dannes av en eller flere paralleliepipediske blokker eller det kan bestå av et hus inneholdende flere små legemer med forskjellig form som er blitt komprimert. A filter can be formed by one or more parallelepiped blocks or it can consist of a housing containing several small bodies of different shapes that have been compressed.
Et filter kan også fremstilles av et legeme formet som en matte eller strimmel som rulles til formålstjenelig form og plasseres i et hylster. A filter can also be made from a body shaped like a mat or strip which is rolled into a useful shape and placed in a sleeve.
Absorpsjonsmaterialet i filteret er hensiktsmessig elastisk. I slike tilfeller kan filtermaterialet i filteret komprimeres slik at bestanddelen som absorberes fra gassmediet som strømmer gjennom filteret, kan gjenvinnes. The absorption material in the filter is suitably elastic. In such cases, the filter material in the filter can be compressed so that the component absorbed from the gas medium flowing through the filter can be recovered.
Absorpsjonsmaterialet i filteret består hensiktsmessig av polyetylen, polypropylen eller en kopolymer av polyetylen og metakrylsyre. The absorption material in the filter suitably consists of polyethylene, polypropylene or a copolymer of polyethylene and methacrylic acid.
Absorpsjonsmaterialet ifølge oppfinnelsen fremstilles for-trinnsvis av et polyetylengranulat som blandes med små mengder pulveriserte tilsetningsmidler for å danne bobler. Blandingen tilføres det første trinn av en to-trinns ekstruder av skrutypen og oppvarmes til ca. 200°C. Den erholdte smelte føres til det andre ekstrudertrinn hvor temperaturen senkes til 100-150°C og ekstruderes gjennom en ringformet dyse. Et porøst rør oppnås, og røret kjøles innvendig og utvendig med luft og skjæres så i langsgående retning under dannelse av en skumplaststrimmel. Parallellepipediske legemer kan selvfølgelig dannes i stedet for strimler. The absorption material according to the invention is preferably produced from a polyethylene granulate which is mixed with small amounts of powdered additives to form bubbles. The mixture is fed to the first stage of a two-stage screw-type extruder and heated to approx. 200°C. The resulting melt is fed to the second extruder stage where the temperature is lowered to 100-150°C and extruded through an annular die. A porous tube is obtained, and the tube is cooled internally and externally with air and then cut longitudinally to form a foam plastic strip. Parallelepiped bodies can of course be formed instead of strips.
Hvis parallellepipediske legemer fremstilles, plasseres de hensiktsmessig i rammen av en filteranordning. Hvis imid-lertid en matte brukes, må den rulles opp, formes hensiktsmessig og innsettes i et hylster som så plasseres i en filteranordning. If parallelepiped bodies are produced, they are conveniently placed in the frame of a filter device. If, however, a mat is used, it must be rolled up, shaped appropriately and inserted into a sleeve which is then placed in a filter device.
Man kan også dele odd den erholdte matte, henholdsvis det paralellepipediske legeme i mindre partikler. Et hylster fylles med nevnte mindre partikler og plasseres i en filteranordning. One can also oddly divide the obtained mat, or the parallelepiped body into smaller particles. A sleeve is filled with said smaller particles and placed in a filter device.
En filteranordning av den ovenfor beskrevne type funksjo-nerer på følgende måte. Gassholdige væskedråper får passere gjennom filteranordningen, hvorpå væskedråpene fanges av absorpsjonsmaterialet og, hvis gassen inneholder bestanddeler som overføres til en væske ved et temperaturfall, vil også væsken som dannes på denne måten absorberes. Når filteranordningen er mettet, fjernes absorpsjonsmaterialet og erstattes med nytt materiale. Absorpsjonsmaterialet i det mettede filter komprimeres så, hvorpå A filter device of the type described above functions in the following way. Gaseous liquid droplets are allowed to pass through the filter device, whereupon the liquid droplets are captured by the absorption material and, if the gas contains constituents which are transferred to a liquid upon a drop in temperature, the liquid thus formed will also be absorbed. When the filter device is saturated, the absorption material is removed and replaced with new material. The absorbent material in the saturated filter is then compressed, whereupon
det absorberte materialet kan gjenvinnes for ny bruk. Etter komprimering er absorpsjonsmaterialene igjen an-vendelige. Et absorpsjonsmateriale er således produsert som ikke bare absorberer væskepartikler, men også mulig-gjør gjenvinning av disse partikler slik at materialet igjen kan anvendes som et filter. the absorbed material can be recovered for new use. After compression, the absorption materials are usable again. An absorption material has thus been produced which not only absorbs liquid particles, but also enables recycling of these particles so that the material can again be used as a filter.
En endeløs strimmel kan fremstilles fra matten av absorpsjonsmaterialet nevnt ovenfor. Strimmelen får da løpe over to ruller hvorav en drives. En strimmel anordnet på ruller plasseres i en filteranordning slik at en gass får strømme gjennom en del av strimmelen og derpå gjennom en annen del av strijrnielen. Strimmelen vil således absorbere væskepartikler som kan gjenvinnes hvis en ytterligere rulle er anordnet ved en av rullene som presser mot strimmelen. Hver del av strimmelen vil derfor tilføres gass inneholdende væskepartikler ved to forskjellige anledninger < °9 den absorberte væske presses så ut mellom de to samvirkende ruller. An endless strip can be made from the mat of the absorbent material mentioned above. The strip is then allowed to run over two rollers, one of which is driven. A strip arranged on rollers is placed in a filter device so that a gas is allowed to flow through part of the strip and then through another part of the strip. The strip will thus absorb liquid particles which can be recovered if a further roll is arranged at one of the rolls which presses against the strip. Each part of the strip will therefore be supplied with gas containing liquid particles on two different occasions < °9 the absorbed liquid is then pressed out between the two cooperating rollers.
