Opfindelsen angår en indretning ved et kontaktlegeme for væske og gas som angivet i indledningen til krav 1.The invention relates to a device at a liquid and gas contact body as defined in the preamble of claim 1.

Kontaktlegemet er sammensat af flere ovenpå hinanden 5 stående kontaktblokke, som kan bestå af et antal parallelle bølgede eller korrugerede kontaktplader, der er adskilt ved hjælp af afstandsorganer, f.eks. ifølge britisk patentskrift 1.496.127 eller mod hinanden stødende og således bølgede, at der dannes gennemgående kanaler 10 mellem pladerne, f.eks. ifølge britisk patentskrift nr. 1.532.170. Herved muliggøres samtidig passage af gas med i det væsentlige vandret og væsken med i det væsentlige lodret strømningsretning. Væsken og gassen kan udgøres af vand henholdsvis luft, og vigtige anvendelsesområder for 15 opfindelsen er luftbefugtningsaggregater og køletårne. Opfindelsen vil i det følgende blive beskrevet i forbindelse med luftbefugtningsaggregater, selv om den ikke er begrænset hertil.The contact body is composed of several superposed contact blocks, which may consist of a plurality of parallel corrugated or corrugated contact plates separated by spacers, e.g. according to British Patent Specification 1,496,127 or against one another and thus corrugated so as to create through-going channels 10 between the plates, e.g. according to British Patent Specification No. 1,532,170. This allows simultaneous passage of gas with substantially horizontal and liquid with substantially vertical flow direction. The liquid and gas can be water or air, respectively, and important areas of application of the invention are humidifiers and cooling towers. The invention will be described in the following in connection with humidifiers, although not limited thereto.

Ved befugtning af luft i et ventilationsanlæg er det sæd-20 vanligt at anvende befugtningsaggregater af den såkaldte indsatstype. Den indkommende luft befugtes heri ved, at den passerer et kontaktlegeme, hvis flader holdes våde gennem kontinuerlig eller diskontinuerlig vandoverrisling. Sædvanligvis strømmer luften vandret gennem kontakt-25 legemet, medens vandet tilføres ved kontaktlegemets øvre del og derefter strømmer nedad langs dets kontaktflader. Vandet kan her tilføres f.eks. ved hjælp af et med huller forsynet rørsystem. En ofte forekommende udførelse for kontaktlegemerne i et befugtningsaggregat indebærer, at 30 disse udgøres af flere blokke anbragt oven på hinanden, således at der dannes mellemrum ved sammenføjningerne mellem blokkene.In humidifying air in a ventilation system, it is customary to use humidifiers of the so-called insert type. The incoming air is wetted herein by passing a contact body whose surfaces are kept wet through continuous or discontinuous water spraying. Usually, the air flows horizontally through the contact body while the water is supplied at the upper part of the contact body and then flows downward along its contact surfaces. Here, the water can be supplied e.g. by means of a hollow tube system. A frequently encountered embodiment for the contact bodies of a wetting assembly involves 30 being constituted by a plurality of blocks arranged one on top of the other so that spaces are formed at the joints between the blocks.

Et problem med hensyn til kontaktlegemer af denne art er, at vanddråber fra mellemrummene mellem blokkene rives med 35 i luftstrømmen, hvilket senere kan medføre ulemper iOne problem with contact bodies of this kind is that water droplets from the spaces between the blocks are teared by 35 in the air flow, which can later cause drawbacks in the

2 ventilationsanlægget. Vandmedrivningen fra mellemrummene optræder, så snart lufthastigheden overstiger en vis værdi, som er afhængig af væskestrømmen. Risikoen for 5 vandmedrivning fra blokkene kan mindskes ved at anbringe kontaktpladerne f.eks. ifølge det britiske patentskrift nr. 1.532.170. Således optræder der som oftest først vandmedrivning af blokkene ved en lufhastighed, som er større end den hastighed, ved hvilken vandmedrivning 10 optræder ved sammenføjningerne. Dette medfører, at lufthastigheden gennem befugtningsaggregatet ofte begrænses opad af risikoen for vandmedrivning fra sammenføjningerne.2 the ventilation system. The water entrainment from the interstices occurs as soon as the air velocity exceeds a certain value which is dependent on the fluid flow. The risk of 5 water entrainment from the blocks can be reduced by placing the contact plates e.g. according to British Patent Specification No. 1,532,170. Thus, most often, water entrainment of the blocks first occurs at an air velocity greater than the velocity at which water entrainment 10 occurs at the joints. This means that the air velocity through the wetting unit is often limited upwards by the risk of water entrainment from the joints.

En kendt måde til at forsøge at afhjælpe denne ulempe er at anbringe en liste i sammenføjningen mellem to blokke på 15 nedstrømssiden set i luftstrømmens retning, der er således udformet, at den opsamler vandet fra den øvre bloks ned-strømsbegrænsningsflade og fører det over til den nedre blok, hvorved vandet samtidig føres lidt imod luftstrømmen. Imidlertid har dette ikke ført til tilfredsstillende 20 resultater, eftersom lufthastigheden stadigvæk begrænses opad af risikoen for vandmedrivning fra sammenføjningerne (ca. 4 m/s).A known way to try to remedy this disadvantage is to place a list in the junction of two blocks on the downstream side seen in the direction of the airflow, which is designed to collect the water from the downstream limiting surface of the upper block and transfer it to the lower block, which at the same time leads the water slightly towards the air flow. However, this has not led to satisfactory results, since the air velocity is still limited upwards by the risk of water entrainment from the joints (about 4 m / s).

Ganske vist kendes fra US-patentskrift nr. 3.947.532 en indretning af den i krav l's indledning nævnte art, dvs.Certainly, from US Patent No. 3,947,532 there is known a device of the kind mentioned in the preamble of claim 1, ie.

25 med en "luftstrømningsbremse" ved sammenføjningens bageste begrænsningslinie, men denne "luftbremse" er anbragt uden for selve kontaktlegemet og tjener faktisk til opsamling af væske, som luftstrømmen har revet løs fra netop denne bageste begrænsningslinie, hvor lufthastigheden 30 åbenbart alligevel er for stor til at væskemedrivning kan undgås.25 with an "air flow brake" at the rear boundary line of the joint, but this "air brake" is disposed outside the contact body itself and actually serves to collect liquid which the air flow has released from just this rear boundary line, where the air velocity 30 is obviously too large for that fluid drift can be avoided.

Opfindelsen har til formål at tilvejebringe en indretning til at mindske risikoen for vandmedrivning i en sammenføjning mellem blokkene i et kontaktlegeme for væske og gas, 35 således at der kan opnås højere lufthastigheder gennem kontaktlegemet. Dette formål opnås ved en indretning, derThe invention has for its object to provide a device for reducing the risk of water entrainment in a joint between the blocks of a liquid and gas contact body, so that higher air velocities can be obtained through the contact body. This object is achieved by a device which

3 er udformet som angivet i den kendetegnende del af krav 1. Hensigtsmæssige udførelsesformer fremgår af de efterfølgende underkrav.3 is designed as defined in the characterizing part of claim 1. Appropriate embodiments are set forth in the following subclaims.

5 Opfindelsen bygger på den erkendelse, at en vanddråbe, som slipper den øvre blok i sammenføjningen mellem en øvre og en nedre blok, fortrinsvis i nærheden af sammenføjningens nedstrøms eller bageste begrænsningslinie, rives med den i det væsentlige vandrette luftstrøm gennem kontaktlegemer-10 ne, så snart lufthastigheden overskrider en vis værdi af størrelsesordenen 2 m/s, og at en effektiv måde til at forhindre vandmedrivning fra sammenføjningerne ved højere lufthastighed gennem kontaktlegemerne er kraftigt at reducere lufthastigheden i og omkring sammenføjningens 15 nedstrøms begrænsningslinie ved at anbringe den som "luftbremse" fungerende hindring opstrøms for denne linie, dvs. inden i selve sammenføjningsområdet, hvor den har vist sig betydeligt mere effektiv til at nedsætte lufthastigheden ved det kritiske sted, nemlig sammenføjningens 20 nedstrøms begrænsningslinie, end den fra ovennævnte US-patentskrift nr. 3.947.532 kendte "luftbremse".The invention is based on the recognition that a drop of water which releases the upper block in the joint between an upper and a lower block, preferably in the vicinity of the downstream or rear boundary line of the joint, is teared by the substantially horizontal air flow through the contact bodies. as soon as the air velocity exceeds a certain value of the order of 2 m / s, and that an effective way of preventing water entrainment from the joints at higher air velocity through the contact bodies is to greatly reduce the air velocity in and around the downstream limiting line of the joint by placing it as "air brake" functioning obstacle upstream of this line, i.e. within the joint area itself, where it has been found to be significantly more effective in reducing the airspeed at the critical location, namely the downstream boundary line of the joint 20, than the "air brake" known from the aforementioned U.S. Patent No. 3,947,532.

Opfindelsen forklares nærmere i det følgende ved et eksempel på en udførelsesform for opfindelsen anvendt på et kontaktlegeme af kendt art under henvisning til tegnin-25 gen, hvor fig. 1 viser et kontaktlegeme med flere kontaktblokke, set i perspektiv, fig. 2 en indretning ifølge opfindelsen og omgivende dele af en øvre og en nedre kontaktblok, set i perspektiv, og 30 fig. 3 tværsnit af alternative udførelsesformer for indretningen.The invention is further explained in the following by an example of an embodiment of the invention applied to a contact body of the prior art with reference to the drawing, in which fig. 1 is a perspective view of a contact body with several contact blocks; FIG. 2 is a perspective view of a device according to the invention and surrounding parts of an upper and a lower contact block; and FIG. 3 cross-section of alternative embodiments of the device.

4 I fig. 1 er et kontaktlegeme 1 placeret i en luftstrøm S og sammensat af flere på hinanden stående kontaktblokke 2, hvorved der i sammenføjningerne mellem blokkene dannes 5 mellemrum 3. Vandet tilføres ved kontaktlegemets øvre del ved hjælp af et med huller forsynet rørsystem 4 og strømmer nedad langs lodret anbragte, bølgede og mod hinanden stødende kontaktplader 5 og 6, som beskrevet i det britiske patentskrift nr. 1.532.170. Ifølge opfindelsen er 10 en hindring 8 anbragt foran den bageste begrænsningslinie 7b af mellemrummet 3 og bag dets forreste begrænsningslinie 7a. Gennem hindringen 8 skabes et område med kraftigt reduceret lufthastighed i og omkring den bageste begrænsningslinie 7b.4 In FIG. 1, a contact body 1 is located in an air stream S and is composed of several contiguous contact blocks 2, whereby 5 spaces are formed in the joints between the blocks. vertically arranged, corrugated and abutting contact plates 5 and 6, as described in British Patent Specification No. 1,532,170. According to the invention, an obstruction 8 is placed in front of the rear boundary line 7b of the gap 3 and behind its front boundary line 7a. Through the barrier 8, an area of greatly reduced air velocity is created in and around the rear boundary line 7b.

15 I fig. 2 er vist i detaljer en hindring 8 anbragt mellem to kontaktblokke 2, en øvre blok 21 og en nedre blok 22. Hindringen 8 er udformet som en plan plade og er anbragt i spor 9 og 10 i kontaktblokkene henholdsvis 21 og 22. Ved anvendelse af opfindelsen i befugtningsaggregater kan hin-20 dringens højde a være mellem 10 og 50 mm, medens dens afstand b til den bageste begrænsnings linie 7b kan være mellem 0,2 a og 3 a, fortrinsvis mellem 0,5 a og a. Hindringen 8 er hermed anbragt langs hele længden af blokkene 21 og 22 eller begrænsningslinien 7b. Med en hin-25 dring ifølge denne udførelsesform med højden a = 30 mm og afstanden b = 0,67 x a = 20 mm anvendt på den type kontaktlegeme, som er beskrevet i det britiske patentskrift nr. 1.532.170, hvis totale dybde går op til omkring 200 mm, har prøver vist, at vandmedrivning fra mellem-30 rummene først optræder ved lufthastigheder op til 6 m/s, hvilket overstiger den hastighed, ved hvilken der sker vandmedrivning fra kontaktblokkene. Selv om hindringen her er udformet som en lodret anbragt plade, er opfindelsen ikke begrænset hertil, men hindringen kan udformes på 35 mange alternative måder.'Andre eksempler på hindringer er vist i fig. 3, hvor fig. 3a viser en udformning, hvor hindringen 8 er anbragt med en hældning i luftstrømmensIn FIG. 2, an obstacle 8 is shown in detail between two contact blocks 2, an upper block 21 and a lower block 22. The obstacle 8 is designed as a flat plate and is placed in tracks 9 and 10 in the contact blocks 21 and 22. respectively. the invention in wetting assemblies, the height a of the obstacle 20 may be between 10 and 50 mm, while its distance b to the rear restriction line 7b may be between 0.2 a and 3 a, preferably between 0.5 a and a. The obstacle 8 is being disposed along the entire length of blocks 21 and 22 or the constraint line 7b. With an obstruction according to this embodiment having the height a = 30 mm and the distance b = 0.67 xa = 20 mm applied to the type of contact body described in British Patent Specification No. 1,532,170, the total depth of which increases to about 200 mm, tests have shown that water entrainment from the interstitial compartments first occurs at air velocities up to 6 m / s, exceeding the velocity at which water entrainment occurs from the contact blocks. Although the barrier here is designed as a vertically arranged plate, the invention is not limited thereto, but the obstacle can be designed in many alternative ways. Other examples of obstacles are shown in FIG. 3, wherein FIG. 3a shows a configuration in which the obstruction 8 is arranged with a slope in the air flow

5 retning. Ifølge fig. 3b er hindringen udformet med to grene 8a og 8b hældende mod retningen af luftstrømmen S, og i fig. 3c er grenene hældende med luftstrømmens 5 retning.5 direction. According to FIG. 3b, the barrier is formed with two branches 8a and 8b inclined towards the direction of the air flow S, and in FIG. 3c, the branches are inclined with the direction of air flow 5.

Hindringen kan ifølge det ovenstående udformes som plader, men også ved at luftkanalerne blokeres på anden måde.According to the above, the obstruction can be designed as plates, but also by blocking the air ducts in another way.

Dette kan f.eks. gennemføres ved at deformere kontaktpladerne inden for det område, som er bestemt til at danne 10 hindringen.This can be done, for example. is accomplished by deforming the contact plates within the region intended to form the obstruction.
