CLASS I NTERNATI ONELLSVENSK B 01 d12 e: 3/01 PATENT AND REGISTRATION AGENCY Ans. The present invention relates to a set and a device for degassing of liquid shoes, especially liquid hydrocarbons such as electric transformers for insulating oils. . The principle of degassing water shoes is usually that the water is allowed to pass through a man, as Mlles under vacuum. To facilitate degassing, the liquid in the vacuum vessel must pass in thin layers over large areas. These aro arranged at intervals arranged plates, rings of various kinds or ph in the vessel fixed springs. The living devices are provided with so-called filter lights arranged in a vacuum vessel for separating liquid mist from gases. However, all hitherto known devices have proved to be unsatisfactory for various reasons. Most of them are very space-consuming and expensive to manufacture, without complete degassing of the water tanks being gained. By means of the present invention, the higher requirements which are now imposed on the purity of insulating oils can be satisfied.
Sattet enligt uppfinningen omfattar atgarden, att vatskan infores i ena anden av ett vertikalt karl, varefter vatskan fhr passera inifran och ut genom i karlet anbragta ringformiga staplar av tunna, plana pappersskivor eller -ringar av filterharaktfir, varpa franskilid gas utpumpas ur karlet och den renade vatskan -Hates avgá vid karlets nedre ande och kannetecknas darav, att ett antal skalforma& platar placeras pa i huvudsak jamnt fordelade avstand Iran varandra mellan pappersskivorna eller -ringarna, varvid platarnas botten vandes uppat. Harigenom begransas ytskiktets tjocklek och ger stapeln full effektivitet. I en avgasare kan staplarnas antal och langd bestammas godtyckligt. The set according to the invention comprises the act of inserting the liquid into one spirit of a vertical vessel, after which the liquid is passed inside and out through annular stacks of thin, flat paper sheets or rings of filter resin, arranged in the vessel, a warp of separated gas being pumped out of the vessel and the purified the water -Hates depart at the lower spirit of the man and may be characterized by the fact that a number of shell-shaped & plates are placed at substantially evenly spaced distances Iran each other between the paper discs or rings, whereby the bottom of the plates is raised upwards. This limits the thickness of the surface layer and gives the stack full efficiency. In an exhaust, the number and length of the stacks can be determined arbitrarily.
Uppfinningen kommer i del foljande att beskrivas narmare med hanvisning till bifogade ritning, vilken som exempel visar en utforingsform av en anordning liimplig for utforande av det nya forfarandet.

Gaserna utsuges genom anslutningen 3. I karlets Ovre del Or infast en med hal forsedd platta 7. Genom varje hal Or med spelrum ford en stay 5, pa vars nedre dude Or fast en andbricka 6.

Staplarnas antal och langd kan givetvis varieras frau fall till fall. Genom lampligt avpassad fjaderkraft pressas papperen i erforderlig grad mot varandra resp. mot platarna titan att forhindra passage av vatskan mellan pappersskivorna eller mellan pappersskivorna och platarna. Nar vatskan strommar genom filterpackarna Or inotstAndet I dessa jfimnt fordelat, varfor vfitskestromningen ock- sOatt bli jamnt fordelad. Genom lampligt val av papper eller liknande material kan vatskeskiktet vid utloppet mellan pappersringarna nedbringas till mindre On 0,001 mm. Genom att vatskeytan utanpa papperen blir vertikal forefinnes inget vatsketryek, som motverkar avgasningen. Nagra vfitskedroppar, som genom hog ytspanning motverkar avgasningen bildas icke. The invention will be described in more detail in the following with reference to the accompanying drawing, which as an example shows an embodiment of a device suitable for carrying out the new method. The figure shows a device comprising a vessel, in which, for example, insulating oils can be degassed. The liquid is fed at the man's upper spirit 1 and out- Dupl. at 12 d: 12/02 is pumped in its lower spirit 2. The gases are sucked out through the connection 3. In the upper part of the vessel a plate provided with a halo is attached. duck washer 6. On the rod Oro thread a large number of thin, flat paper sheets or rings 4 of filter character, which abut against the duck washer 6 and the plate 7. A helical spring 8 Or placed around the rod on the other side of the plate and stands against one on the rod hnde arranged counter. Between the paper sheets Oro arranged a number of shell-shaped plates 9, the bottom of which is validly raised and which Oro placed on substantially evenly spaced distances from each other. The number and length of the bars can of course be varied from case to case. By suitably adapted spring force, the papers are pressed against each other to the required degree resp. against the sheets of titanium to prevent the passage of the liquid between the sheets of paper or between the sheets of paper and the sheets. When the liquid flows through the filter packs or is not evenly distributed in them, the liquid flow also becomes evenly distributed. By suitable choice of paper or similar material, the liquid layer at the outlet between the paper rings can be reduced to less On 0.001 mm. Because the water surface on the outside of the paper becomes vertical, there is no liquid pressure which counteracts the degassing. Some vfit spoon droplets, which by high surface tension counteract the degassing, are not formed.
