Description

Oppfinnelsen angår et kontaktlegeme for væske og gass ifølge innledningen til patentkrav 1. Væsken og gassen kan ut-gjøres av vann henholdsvis luft, og et viktig anvendelsesområde for oppfinnelsen er luftfuktere, men oppfinnelsen er ikke be-grenset til sådanne. The invention relates to a contact body for liquid and gas according to the introduction to patent claim 1. The liquid and gas can be water or air, respectively, and an important area of application for the invention is air humidifiers, but the invention is not limited to such.

Ved oppfukting av luft i ventilasjonsanlegg er det vanlig å benytte luftfuktere av såkalt innsatstype. Den inn-kommende luft fuktes da ved at den får passere et kontaktlegeme hvis overflater holdes våte ved kontinuerlig eller diskontinuer-lig vannoverrisling. Vanligvis strømmer luften horisontalt gjennom kpntaktlegemet mens vannet tilføres ved kontaktlegemets topp og siden strømmer nedover langs dettes kontaktflater. Vannet kan herved eksempelvis tilføres ved hjelp av et hullfor-synt rørsystem. For å tilveiebringe god oppfukting av luften, er det viktig at vannet fordeles så jevnt som mulig.over kontaktlegemets flater. When humidifying air in ventilation systems, it is common to use humidifiers of the so-called insert type. The incoming air is then moistened by allowing it to pass a contact body whose surfaces are kept wet by continuous or discontinuous water sprinkling. Usually the air flows horizontally through the contact body while the water is supplied at the top of the contact body and then flows downwards along its contact surfaces. In this way, the water can, for example, be supplied by means of a pipe system equipped with holes. In order to provide good humidification of the air, it is important that the water is distributed as evenly as possible over the surfaces of the contact body.

Kontaktlegemet utgjøres ofte av et stort antall parallelt anbragte, korrugerte kontaktplater som støtter seg mot hverandre eller er forsynt med avstandsorganer slik at det dannes passende store kanaler for at vann- og luftstrømmene skal kunne passere gjennom kontaktlegemet. Et eksempel på et The contact body is often made up of a large number of parallel arranged, corrugated contact plates that support each other or are provided with spacers so that suitably large channels are formed for the water and air flows to be able to pass through the contact body. An example of a

slikt kontaktlegeme er angitt i norsk patentsøknad nr. 76 0823. En vanskelighet i forbindelse med kontaktlegemer av denne type er å oppnå jevn vannfordeling over platene ved meget små vann-strømmer, særlig når det velges plater av ikke-hygroskopisk such a contact body is specified in Norwegian patent application no. 76 0823. A difficulty in connection with contact bodies of this type is to achieve uniform water distribution over the plates with very small water flows, especially when plates of non-hygroscopic

materiale, men også svakt'hygroskopisk materiale. material, but also weakly hygroscopic material.

Den foreliggende, oppfinnelse, som har som formål å tilveiebringe en bedre vannfordeling og en bedre vannfasthol-delse over kontaktlegemet ved små -vannstrømmer, er kjennetegnet ved at de folder som danner finstruktur på platene med i hovedsaken vertikale folder i grovstrukturen, er i hovedsaken horisontale, mens de folder som danner finstruktur på platene med i hovedsaken horisontale folder i grovstrukturen, er i hovedsaken vertikale for oppnåelse av god vedheftning og gunstig fordeling av væsken på platene. The present invention, which aims to provide a better water distribution and a better water retention over the contact body with small water flows, is characterized by the fact that the folds that form a fine structure on the plates with mainly vertical folds in the coarse structure are mainly horizontal , while the folds that form a fine structure on the plates with mainly horizontal folds in the coarse structure are mainly vertical to achieve good adhesion and favorable distribution of the liquid on the plates.

Fordelaktige utførelsesformer er angitt i de etter-følgende underkrav. Advantageous embodiments are specified in the subsequent subclaims.

Til grunn for oppfinnelsen ligger den erkjennelse at det vann som tilføres til en kontaktplate som er forsynt med en i hovedsaken vertikal grovstruktur overlagret på en i hovedsaken horisontal finstruktur, av finstrukturen fordeles over platen, mens det av grovstruktux_en holdes tilbake slik at med-rivning av vanndråper i luftstrømmen elimineres. Omvendt for-søker grovstrukturen på en kontaktplate, som er forsynt med en i hovedsaken horisontal grovstruktur overlagret på en i hovedsaken vertikal finstruktur, å fordele vannet mens finstrukturen forsøker å holde vannet tilbake. Det er således vesentlig for oppfinnelsen at fin- og grovstrukturenes foldehøyde, bølgeleng-de og form tilpasses til hverandre slik at ønsket avveining mellom fordeling og tilbakeholdelse av vannet oppnås.. The invention is based on the recognition that the water supplied to a contact plate which is provided with a mainly vertical coarse structure superimposed on a mainly horizontal fine structure is distributed over the plate by the fine structure, while it is held back by the coarse structure so that tearing of water droplets in the air stream are eliminated. Conversely, the coarse structure on a contact plate, which is provided with a mainly horizontal coarse structure superimposed on a mainly vertical fine structure, tries to distribute the water while the fine structure tries to hold the water back. It is thus essential for the invention that the folding height, wavelength and shape of the fine and coarse structures are adapted to each other so that the desired balance between distribution and retention of the water is achieved.

Oppfinnelsen skal beskrives nærmere i det følgende under henvisning til tegningene, der fig. 1 viser et perspektivriss av kontaktlegemet, fig. 2a og 2b viser perspektivriss av kontaktplatene, fig. 3 viser et tverrsnitt av en kontaktplate vinkelrett.på grovstrukturen, og fig. 4 viser ét tverrsnitt av en kontaktplate vinkelrett på finstrukturen. The invention will be described in more detail below with reference to the drawings, where fig. 1 shows a perspective view of the contact body, fig. 2a and 2b show perspective views of the contact plates, fig. 3 shows a cross-section of a contact plate perpendicular to the rough structure, and fig. 4 shows a cross-section of a contact plate perpendicular to the fine structure.

Slik det fremgår av fig. 1, er kontaktlegemet anbragt i en luftstrøm 7. Vanntilførselen for legemets fukting skjer med et rørsystem 8. Kontaktlegemet består av et antall vertikalt stående og parallelt anordnede, mot hverandre anliggende kontaktplater som i kontaktpunktene kan være sammenføyd med et passende bindemiddel (lim). De folder 3 som danner grovstruktur på annenhver plate 1, er i hovedsaken vertikale og" overlagret på de folder 5 som danner finstruktur og som er i hovedsaken horisontale. Omvendt er de folder 4 som danner grovstruktur på tilgrensende plater 2, i hovedsaken horisontale og over lagret på de folder 6 som danner finstruktur og som er i hovedsaken vertikale. Av fig. 2a, 2b, 3 og 4 fremgår den nærmere utforming av platene. Grovstrukturen 3 på platene 1 med i hovedsaken vertikale folder i grovstrukturen kan hensiktsmessig ha en foldehøyde a-^ mellom 2 og 6 mm og en bølgelengde X-^mellom 5 og 15 mm, mens grovstrukturen 4 på' platene 2 med i hovedsaken horisontale folder-i.grovstrukturen kan ha en foldehøyde a-^mellom. 5 og 15 mm og en bølgelengde X^mellom 10 og 30 mm. Finstrukturene 5 og 6 kan hensiktsmessig ha en foldehøyde & 2 mellom 0,3 og 2 mm og en bølgelengde X2mellom 1 og 6 mm. Med foldehøyde (a) menes avstanden mellom bølgedal og bølgetopp, dvs. platens tykkelse er ikke innbefattet i denne avstand. Foldene som danner grovstruktur henholdsvis finstruktur, kan velges sinusformede, trekantede (med mer eller mindre mykt avrundede topper og daler) eller trapes-formede. As can be seen from fig. 1, the contact body is placed in an air stream 7. The water supply for wetting the body takes place with a pipe system 8. The contact body consists of a number of vertically standing and parallel arranged contact plates that abut one another at the contact points can be joined with a suitable binder (glue). The folds 3 which form a coarse structure on every other plate 1 are mainly vertical and are superimposed on the folds 5 which form a fine structure and which are mainly horizontal. Conversely, the folds 4 which form a coarse structure on adjacent plates 2 are mainly horizontal and above stored on the folds 6 which form a fine structure and which are mainly vertical. From Fig. 2a, 2b, 3 and 4 the more detailed design of the plates can be seen. The coarse structure 3 on the plates 1 with mainly vertical folds in the coarse structure can conveniently have a folding height a between 2 and 6 mm and a wavelength X between 5 and 15 mm, while the rough structure 4 on the plates 2 with mainly horizontal folds in the rough structure can have a fold height between 5 and 15 mm and a wavelength X^ between 10 and 30 mm. The fine structures 5 and 6 can conveniently have a fold height &2 between 0.3 and 2 mm and a wavelength X2 between 1 and 6 mm. Fold height (a) means the distance between wave trough and wave crest, i.e. the plate's thickness is not included in this distance. The folds that form the coarse structure or the fine structure can be chosen sinusoidal, triangular (with more or less softly rounded peaks and valleys) or trapezoidal.

Et annet område for anvendelse av kontaktlegemer ifølge oppfinnelsen er kjøletårn der grovstrukturen 3 hensiktsmessig kan ha en foldehøyde mellom 5 og 15 mm og en bølgelengde mellom 10 og 40 mm, der grovstrukturen 4 kan ha en foldehøyde mellom 10 og 30 mm og en bølgelengde mellom 25 og 75 mm, og der finstrukturene 5 og 6 kan ha en foldehøyde mellom 1 og 5 mm og en bølgelengde mellom 3 og 15 mm. Ytterligere andre anven-delsesområder er f.eks. utnyttelse eller gjenvinning av spill-varme fra en gass, samt gassabsorpsjon. Another area for the use of contact bodies according to the invention is cooling towers where the rough structure 3 can suitably have a folding height between 5 and 15 mm and a wavelength between 10 and 40 mm, where the rough structure 4 can have a folding height between 10 and 30 mm and a wavelength between 25 and 75 mm, and where the fine structures 5 and 6 can have a folding height between 1 and 5 mm and a wavelength between 3 and 15 mm. Further other areas of application are e.g. utilization or recovery of waste heat from a gas, as well as gas absorption.

Materialet i kontaktplatene kan med fordel være hygroskopisk eller være forsynt med et hygroskopisk overflatesjikt, men materialet kan også være ikke-hygroskopisk. Plate-nes materialtykkelse varierer vanligvis mellom 0,05 og 0,5 mm. The material in the contact plates can advantageously be hygroscopic or be provided with a hygroscopic surface layer, but the material can also be non-hygroscopic. The plates' material thickness usually varies between 0.05 and 0.5 mm.
