Esillä olevan keksinnön kohteena on kosketuskappale nestettä ja kaasua varten, joka kosketuskappale muodostuu useista pystysuorista ja yhdensuuntaisesti sovitetuista, toisiinsa tukeutuvista kosketuslevyistä, joissa on hienot poimut eli aallot, jotka muodostavat ns. hienorakenteen, ja päällekkäiset karkeammat poimut eli aallot, jotka muodostavat ns. karkearakenteen ja joita on kahta laatua ja sovitettuina vuorotellen, jolloin joka toisessa levyssä on pystysuora hienorakenne ja vaakasuora karkearakenne, ja joka toisessa levyssä on pystysuora karkearakenne, niin että levyjen väliin muodostuu läpikulkevia kanavia, joiden kautta samanaikaisesti kaasun, jonka virtaussuunta on pääasiassa vaakasuora, ja nesteen, jonka virtaussuunta on pääasiassa pystysuora, on tarkoitus kulkea. Nesteenä ja kaasuna voi olla vesi ja vastaavasti ilma. Keksinnön tärkeänä käyttöalueena ovat ilmankostuttimet, mutta keksintö ei kuitenkaan rajoitu vain niihin.The present invention relates to a contact piece for a liquid and a gas, which contact piece consists of a plurality of vertical and parallel-arranged, mutually supporting contact plates with fine corrugations, i.e. waves, which form a so-called fine structure, and overlapping coarser folds, i.e. waves, which form the so-called. of two qualities and arranged alternately, each plate having a vertical fine structure and a horizontal coarse structure, and the other plate having a vertical coarse structure so as to form through-passage channels between the plates through which a gas with a substantially horizontal flow direction , whose flow direction is mainly vertical, is intended to pass. The liquid and gas may be water and air, respectively. Humidifiers are an important field of application of the invention, but the invention is not limited to them.
2 621822 62182
Ilman kostutuksessa tuuletuslaltoksissa käytetään tavallisesti ns. panostyyppisiä ilman kostuttimia. Sisääntuleva ilma kostutetaan tällöin antamalla sen kulkea kosketuskappaleen läpi, jonka pinnat pidetään märkinä valelemalla niitä jatkuvasti tai jaksottain vedellä. Tavallisesti ilma virtaa vaakasuoraan kosketuskappaleen läpi, kun taas vettä johdetaan kosketuskappaleen yläosaan, josta se sitten virtaa alaspäin sen kosketuspintoja pitkin. Vettä voidaan tällöin johtaa esim. rei'illä varustetun putkiston avulla. Hyvän ilman kosketuksen kannalta on tärkeää, että vesi jaetaan mahdollisimman tasaisesti kosketuskappaleen pintojen yli.In air humidification, the so-called batch type without humidifiers. The incoming air is then moistened by passing it through a contact piece, the surfaces of which are kept wet by pouring them continuously or intermittently with water. Usually, air flows horizontally through the contact piece, while water is led to the top of the contact piece, from where it then flows downward along its contact surfaces. The water can then be led, for example, by means of piping with holes. It is important for good air contact that the water is distributed as evenly as possible over the surfaces of the contact piece.
Kosketuskappale muodostuu usein suuresta määrästä yhdensuuntaisesti sovitettuja, poimutettuja kosketuslevyjä, jotka tukeutuvat toisiinsa tai on varustettu välike-elimillä, niin että muodostuu sopivan suuria kanavia, jotta vesi- ja ilmavirrat voivat kulkea kosketuskappaleen läpi. Eräs tällaisen kosketuskappaleen esimerkki käy ilmi ruotsalaisesta kuulutusjulkaisusta nso 391 576. Eräänä vaikeutena tämäntyyppisissä kosketuskappaleissa, joissa on pystysuuntainen poimutus, on tasaisen veden jakautumisen aikaansaaminen levyjen yli, kun vesivirrat ovat hyvin pienet, erityisesti silloin kun käytetään levyjä, jotka on valmistettu ei-hygroskooppi-sesta tai myös heikosti hygroskooppisesta aineesta. Tarvitaan varsin monimutkaiset vedensyöttölaitteet.The contact piece often consists of a large number of parallel-arranged, corrugated contact plates which rest on each other or are provided with spacers so as to form suitably large channels so that water and air flows can pass through the contact piece. An example of such a contact piece is given in Swedish Patent Publication No. 391 576. One difficulty with this type of contact piece with vertical corrugation is to obtain an even distribution of water over the plates when the water flows are very small, especially when using plates made of non-hygr. or also from a weakly hygroscopic substance. Quite complex water supply equipment is required.
Ruotsalaisissa kuulutusjulkaisuissa n:o 305 457 ja n:o 307 964 taas on esitetty kosketuskappaleitä, joissa joka toinen kosketuslevy on varustettu virtaussuunnassa alaspäin kaltevalla karkeapoimutuksella ja joka toinen kosketuslevy on varustettu virtaussuunnassa ylöspäin kaltevalla karkeapoimutuksella. Kosketus-levyt, on lisäksi varustettu pystysuoralla hienopoimutuksella.Swedish Offenlegungsschrift Nos. 305,457 and 307,964, on the other hand, disclose contact pieces in which every second contact plate is provided with a downwardly inclined coarse corrugation in the flow direction and every other contact plate is provided with an upwardly inclined coarse corrugation in the flow direction. The touch plates, in addition, are equipped with vertical fine folding.
Näillä kosketuskappaleilla on kuitenkin sama veden tasainen jakautumiseen liittyvä epäkohta.However, these contacts have the same disadvantage of even water distribution.
Esillä oleva keksintö, jonka tarkoituksena on saada aikaan entistä tasaisempi veden jakautuminen ja veden parempi pysyminen kosketuskappaleen pinnalla, kun vesivirrat ovat pieniä, on tunnettu siitä, että pystysuoralla karkearakenteella varustettujen levyjen hienorakenne on sovitettu vaakasuoraan.The present invention, which is intended to provide a more even distribution of water and better retention of water on the surface of the contact body when the water flows are small, is characterized in that the fine structure of the plates with a vertical coarse structure is arranged horizontally.
3 621823 62182
Keksintö perustuu siihen oivallukseen, että pääasiassa pystysuoralla karkearakenteella sekä sen päälle sijoitetulla pääasiassa vaakasuoralla hienorakenteella varustettuun kosketuslevyyn syötetyn veden jakaa hienorakenne levyn yli, kun taas karkearakenne pidättää vettä, niin ettei ilmavirta voi temmata vesipisaroita mukanaan.The invention is based on the realization that the water fed to a contact plate with a substantially vertical coarse structure and a substantially horizontal fine structure placed on it is distributed by the fine structure over the plate, while the coarse structure retains water so that the air flow cannot entrain water droplets.
Keksinnön mukaisessa kosketuskappaleessa voidaan käyttää niinkin suuria ilmanvirtausnopeuksia kuin n. 5m/s ennenkuin tapahtuu vesipisaroiden mainittavaa mukaantempautumista. Vastaava ilmiö esiintyy tunnetuissa rakenteissa arvossa n. 3m/s. Tämä parannus on varsin merkittävä, kun otetaan huomioon, että ilmankostuttimet yleensä määräävät ilmanvaihtolaitteiden muun mitoituksen. Pienikokoinen ilmankostutin tekee mahdolliseksi sen, että myös laitteen muut osat voidaan valita pienemmiksi. Verrattuna tunnettuihin ratkaisuihin on kosketuskappaleen tehokkuus saatu suurin piirtein kaksinkertaiseksi, ja tämä on voitu toteuttaa vesikuormituksella, joka on noin puolet entisestä. Keksinnön kannalta on siis oleellista, että hieno- ja karkearakenteiden poimun korkeus, poimun pituus ja muoto sovitetaan toistensa mukaan, niin että veden jakautumisen ja pidätyksen välille saadaan haluttu suhde.In the contact piece according to the invention, air flow velocities as high as about 5 m / s can be used before a significant entrainment of water droplets occurs. A similar phenomenon occurs in known structures at a value of about 3 m / s. This improvement is quite significant, given that humidifiers generally dictate the other dimensions of ventilation equipment. The compact humidifier makes it possible to select other parts of the appliance as smaller. Compared to the known solutions, the efficiency of the contact piece has been roughly doubled, and this has been possible with a water load of about half of the former. It is therefore essential for the invention that the corrugation height, corrugation length and shape of the fine and coarse structures are adapted to each other so that the desired relationship between water distribution and retention is obtained.
Keksintöä selitetään seuraavassa lähemmin viitaten oheisiin piirustuksiin, joissa kuvio 1 esittää perspektiivikuvaa kosketuskappaleesta, kuvio 2a ja 2b esittävät perspektiivikuvia kosketuslevyistä, kuvio 3 esittää poikkileikkausta kosketuslevystä suorakulmaisesta karkearakennetta vastaan, ja kuvio 4 esittää poikkileikkausta kosketuslevystä suorakulmaisesta hienorakennetta vastaan.The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a perspective view of a contact body, Figures 2a and 2b show perspective views of contact plates, Figure 3 shows a cross-section of a contact plate against a rectangular rough structure, and Figure 4 shows a cross-section against a contact plate rectangle.
Kuten kuviosta 1 käy ilmi, kosketuskappale on sijoitettu ilmavirtaan 1. Veden syöttö kappaleen kosketusta varten tapahtuu putkistolla 8. Kosketuskappale muodostuu useista pystysuorista ja yhdensuuntaisesti sovitetuista, toisiinsa tukeutuvista kosketus-levyistä, jotka voidaan liittää yhteen kosketuspisteissä sopivalla sideaineella (liimalla).As can be seen in Figure 1, the contact piece is placed in the air stream 1. The water supply for contacting the piece takes place via a piping 8. The contact piece consists of several vertical and parallel, interlocking contact plates which can be joined together at the contact points by a suitable binder (adhesive).
Poimut 3, jotka muodostavat karkearakenteen joka toiseen levyyn 1, ovat pääasiassa pystysuoria ja ne on sijoitettu poimujen 5 päälle, jotka muodostavat hienorakenteen ja ovat pääasiassa vaakasuoria. Kääntäen poimut 4, jotka muodostavat karkearakenteen vie- 4 62182 reisissä levyissä 2, ovat pääasiassa vaakasuoria ja ne on sijoitettu poimujen 6 päälle, jotka muodostavat hienorakenteen ja ovat pääasiassa pystysuoria. Levyjen tarkempi rakenne käy ilmi kuvioista 2a, 2b, 3 ja 4. Levyjen 1 karkearakenteessa 3, jossa on pääasiassa pystysuoria poimuja, voi sopivasti olla poimun korkeus (a^) 2-6 mm ja aallon pituus (Λ^) 5-15 mm, kun taas levyjen 2 karkearakenteessa 4, jossa on pääasiassa vaakasuoria poimuja, voi olla poimun korkeus (a^) 5-15 mm ja aallon pituus (Λ^) 10-30 mm. Hienorakenteessa 5 ja 6 voi sopivasti olla poimun korkeus (aj) 0,3-2 mm ja aallon pituus (A g) 1-6 n®· Poimun korkeudella (a) tarkoitetaan aallon pohjan ja aallon harjan välistä etäisyyttä, ts. levyn paksuus ei sisälly tähän etäisyyteen. Karkearakenteen ja hienorakenteen muodostavat poimut voidaan valita sinimuotoisiksi, kolmiomaisiksi (enemmän tai vähemmän pehmeästi pyöristetyin kär-jin ja pohjin) tai puolisuunnikkaan muotoisiksi.The corrugations 3, which form a coarse structure on every other plate 1, are substantially vertical and are placed on top of the corrugations 5, which form a fine structure and are substantially horizontal. Conversely, the corrugations 4, which form a coarse structure in the flaps 4 62182 in the thighs 2, are substantially horizontal and are placed on top of the corrugations 6, which form a fine structure and are substantially vertical. The more detailed structure of the plates can be seen in Figures 2a, 2b, 3 and 4. The coarse structure 3 of the plates 1, which has mainly vertical corrugations, may suitably have a corrugation height (α) of 2-6 mm and a wavelength (α) of 5-15 mm, while the coarse structure 4 of the plates 2, which has mainly horizontal corrugations, may have a corrugation height (a ^) of 5-15 mm and a wavelength (^ ^) of 10-30 mm. The fine structure 5 and 6 may suitably have a corrugation height (aj) of 0.3-2 mm and a wavelength (A g) of 1-6 n® · The corrugation height (a) means the distance between the bottom of the wave and the crest of the wave, i.e. the thickness of the plate is not included in this distance. The corrugations forming the coarse structure and the fine structure can be chosen to be sinusoidal, triangular (more or less softly rounded with a tip-and-bottom) or trapezoidal.
Keksinnön mukaisten kosteuskappaleiden eräänä käyttöalueena ovat jäähdytystornit, joissa karkearakenteessa 3 voi sopivasti olla poimun korkeus 5-15 mm ja aallon pituus 10-40 mm, karkearakenteessa 4 poimun korkeus 10-30 mm ja aallon pituus 210-40 mm, karkearakenteessa 4 poimun korkeus 10-30 mm ja aallon pituus 25-75 mm sekä hienorakenteissa 5 ja 6 poimun korkeus 1-5 mm ja aallon pituus 3-15 mm. Vielä muita sovellutusalueita ovat esim. hukkalämmön talteenotto kaasusta sekä kaasun absorptio.One area of application for the moisture bodies according to the invention is cooling towers, in which the coarse structure 3 can suitably have a corrugation height of 5-15 mm and a wavelength of 10-40 mm, the coarse structure 4 has a corrugation height of 10-30 mm and a wavelength of 210-40 mm, the coarse structure 4 has a corrugation height of 10- 30 mm and wavelength 25-75 mm, and in fine structures 5 and 6 the height of the corrugation is 1-5 mm and the wavelength is 3-15 mm. Still other areas of application are, for example, the recovery of waste heat from gas and the absorption of gas.
Kosketuslevyjen aine voi edullisesti olla hygroskooppista tai varustettu hygroskooppisella pintakerroksella, mutta aine voi myös olla ei-hygroskooppista. Levyjen aineen paksuus vaihtelee tavallisesti välillä 0,05-0,5 mm.The material of the contact plates may preferably be hygroscopic or provided with a hygroscopic surface layer, but the material may also be non-hygroscopic. The thickness of the material of the sheets usually varies between 0.05 and 0.5 mm.
