Description
Innretning til utskillelse i fast form bestanddeler fra en gassblanding ved avkjøling. Device for separating in solid form components from a gas mixture during cooling.
Oppfinnelsen vedrører en innretning til utskillelse av bestanddeler i fast form fra en gassblanding ved avkjøling. The invention relates to a device for separating components in solid form from a gas mixture during cooling.
Det er ofte ønskelig, f. eks. ved luft-renseanlegg og ved koldgassavkjølingsma-skiner som på sitt kolde hode kan kon-densere gass å befri den tilførte gassblanding før den atskilles eller kondense-res for bestanddeler som vanndamp og kullsyre, som utskiller seg ved avkjølingen ved meget høyere temperaturer enn den som finner sted ved utskillelsen eller kon-densasjonen i form av is eller sne, og kan være forstyrrende fordi de tilstopper ka-naler f. eks. i varmeutvekslere, eller kan forurense kondensatene som f. eks. ved fly-tendegjort luft viser seg ved en uønsket uklarhet. It is often desirable, e.g. at air purification plants and at cold gas cooling machines that can condense gas on its cold head to free the supplied gas mixture before it is separated or condensed from components such as water vapor and carbon dioxide, which are separated during cooling at much higher temperatures than that which takes place during the secretion or condensation in the form of ice or snow, and can be disruptive because they clog channels, e.g. in heat exchangers, or can contaminate the condensates such as in the case of fly-tended air manifests itself by an undesirable cloudiness.
For dett formål er det allerede kjent flere innretninger. Several devices are already known for this purpose.
Det er f. eks. kjent en innretning til It is e.g. known a device to
utskillelse i fast form bestanddeler fra en gasblanding ved avkjøling, idet det er anordnet en gassgjennomtrengelig støtte som en vegg av gas i gassblandingsstrømmen, hvilken støtte er forbundet med en av-kjølingsinnretning, således at bestanddelen kan avleire seg i form av sne på støtten. separation in solid form of components from a gas mixture during cooling, as a gas-permeable support is arranged as a wall of gas in the gas mixture flow, which support is connected to a cooling device, so that the component can deposit in the form of snow on the support.
Det har overraskende vist seg at det It has surprisingly turned out that
med en slik innretning er mulig på gasen å oppbygge et snelag kontinuerlig mot til-strømningsretningen av den gass som skal renses, og som forblir sprø i en slik grad at sogar ved temmelig store styrker forblir strømningsmotstanden av gassen i snelaget under en egnet verdi. De bestanddeler with such a device, it is possible to build up a snow layer on the gas continuously against the direction of flow of the gas to be purified, and which remains brittle to such an extent that even at fairly large forces, the flow resistance of the gas in the snow layer remains below a suitable value. The constituents
som skal utskilles lagrer seg da bare ikke på snelaget, men også i snelaget, uten imidlertid at dette tilstoppes med en gang. which is to be secreted is then stored not just on the snow layer, but also in the snow layer, without, however, this being blocked immediately.
Det viste seg imidlertid at den nevnte egenskap bare består når den gassgjen-nomtrengelige vegg, i det følgende kalt gasen, avkjøles godt. Det må følgelig fore-gå en kontinuerlig kuldetransport mellom en annen kuldekilde enn gassen selv og gasen, således at det også i snelaget over dettes tykkelse kontinuerlig opprettholdes en temperaturgradient. It turned out, however, that the aforementioned property only persists when the gas-permeable wall, hereafter called the gas, cools well. Consequently, there must be a continuous transport of cold between a cold source other than the gas itself and the gas, so that a temperature gradient is also continuously maintained in the snow layer over its thickness.
Ved en slik utskillelsesinnretning opptrer nu følgende foreteelse. Når allerede et snelag er blitt dannet lagrer den samlede kullsyre seg i sneen i den umiddelbare nær-het av gasen. Da bestemmes motstanden av dette kullsyrelag som bare er noen mm tykt, gasens belastbarhet. With such a separation device, the following phenomenon now occurs. When a layer of snow has already formed, the total carbon dioxide is stored in the snow in the immediate vicinity of the gas. Then the resistance of this carbonic acid layer, which is only a few mm thick, determines the load capacity of the gas.
Oppfinnelsens formål er å skaffe en The object of the invention is to provide a
løsning for disse vanskeligheter. solution for these difficulties.
Ifølge oppfinnelsen er det på støtten anbragt et lag som har egenskaper tilsvarende egenskapene av en på gasen av-lagret grov sne, og at støtten selv består av et slikt lag. According to the invention, a layer is placed on the support which has properties corresponding to the properties of coarse snow deposited on the gas, and that the support itself consists of such a layer.
Laget kan f. eks. bestå av: The team can e.g. consist of:
1. Et antall gaslag som er oppviklet løst 1. A number of layers of gas that are wound loosely
rundt den egentlige sneoppfangende gas. around the actual snow collecting gas.
2. En grovere gas enn den egentlige sneoppfangende gas som holdes i en viss avstand fra sistnevnte. 3. Et filtlag, f. eks. av glassull eller 2. A coarser gas than the actual snow-trapping gas which is kept at a certain distance from the latter. 3. A layer of felt, e.g. of glass wool or
regeneratormasse som består av tråd. regenerator mass consisting of wire.
4. Et skikt av tynne metalltråder som ligger uorientert (Metallull). 4. A layer of thin metal wires that are unoriented (Metalwool).
5. En metallplysj (polvevnad). 5. A metal plush (pole weave).
6. En vevnad som glassduk. 6. A fabric like glass cloth.

Ved anvendelsen av oppfinnelsen får By applying the invention,
man en dybdevirkning før gasen, dvs. før den tilstrømmende gass har passert gasen. one has a depth effect before the gas, i.e. before the inflowing gas has passed the gas.
Den tilstrømmende gass foravkjøles før The inflowing gas is pre-cooled before
den egentlige gas nåes. Det viste seg da at det til å begynne med på den egentlige gas danner seg temmelig grove snekrystaller, the actual gas is reached. It then turned out that initially rather coarse snow crystals form on the actual gas,

Det er en fordel at det ikke opptrer noen grov tåke-dannelse i tilstrømmende gass fordi gas- which have a larger space between them to collect further snow. It is an advantage that no coarse fog formation occurs in the inflowing gas because gas-

The coldness of these parts is evenly balanced due to the presence of the layer according to the invention. Snow formation also starts faster due to the presence of this layer.
