Gasen mottas infedningsvis filterenheternas 18 invandiga utrymmen 20. Da gasen leds radiellt utat i de invandiga utrymmen 20 leder de lutande vaggele- menten 21 gasen nedat mot filterutrymmet 22 med filtermateri- alet 23. Gasen leds darvid genom filtermateriaiet 23 sa att den kommer i kontakt med zeoliternas silverdopning. Darmed sker en kemisk reaktion vid vilken jod, t.ex. i form av metyljodid fangas upp renas. In the event of a filtered pressure relief, gas flows through the pressure relief line 4. The gas in the reactor containment 5 is thus led, via line 4, to the ordinary filter the arrangement 2. After the gas has passed through the ordinary filter arrangement 2, it is led to the supplementary filter arrangement 1. The gas flowing into the supplementary filter arrangement is led, via the distribution pipe 12, in a vertical direction In the container 10. The gas is led substantially fig-shaped from the distribution tube 12, via the radial outlet openings 16, to the respective filter units 18. The gas is received in an inhaled manner from the inner spaces 20 of the filter units 18. the gas 21 downwards towards the filter space 22 with the filter material alet 23. The gas is thereby passed through the filter material 23 so that it comes into contact with the silver doping of the zeolites. Thereby a chemical reaction takes place in which iodine, e.g. in the form of methyl iodide is captured purified.
Efter att gasen strOmmat igenom filtermaterialet 23 mottas den i det utvandiga utrymmet 25 som är belaget mellan tva filterenheter 18. Gasen leds radiellt utat i det utvandiga utrymme 25 tills den kommer i kontakt med en invandig yta hos behallaren 10. Gasen leds darefter uppat via en av utloppspassagerna 26 dar den successivt blandas med gas fran de vertikalt ovanfor belagna filterenhetema 18. Gasen leds vidare upp langs behallarens invandiga yta och darefter radiellt inat till en position vasentligen rakt ovanfOr fordelningsroret 12 forsiutna ande. Gasen leds darefter ut via utloppsroret 14 och utloppsoppningen 13. After the gas has flowed through the filter material 23, it is received in the outer space 25 which is occupied between two filter units 18. The gas is led radially outwards in the outer space 25 until it comes into contact with an inner surface of the container. 10. The gas is then led upwards via one of the outlet passages 26 where it is successively mixed with gas from the filter units 18 located vertically above. The gas is passed further up along the inner surface of the container and then radially inwards to a position substantially directly above the distribution pipe 12. The gas is then led out via the outlet pipe 14 and the outlet opening 13.
Gasen som lamnar det kompletterande filterarrangemanget 1 är saledes renad. The gas leaving the complementary filter arrangement 1 is thus purified.

Under drift leds gas in i filterarrangemanget 1, via inloppsoppningen 11. Gasen leds vertikalt nedat i fordelningsroret 12. Oppningarna 16 leder ut gasen vasentligen likformig fran fordel- ningsroret 12 till filterenheterna 18. Darmed mottar alla filteren- heter 18, via sina inloppsoppningar 19, en vasentligen lika stor mangd gas. Gasen leds in i de filterenhetemas 18 invandiga utrymmen 20. Det nedat lutande vaggelementet 21 avlankar gasen nedat mot det nedre filterutrymmet 22 cla gasen leds radiellt utat 25 1 det invandiga utrymmet 20. Gasen leds darefter nedat genom filtermaterialet 23. Darmed sker en kemisk reaktion vid vilken jod sasom metyljodid fangas upp ur gasen. Gasen som laminar filtermaterialet 23 är darmed renad. During operation, gas is led into the filter arrangement 1, via the inlet opening 11. The gas is led vertically downwards into the distribution pipe 12. The openings 16 discharge the gas substantially uniformly from the distribution pipe. 12 to the filter units 18. Thus, all the filter units receive 18, via its inlet openings 19, a substantially equal amount of gas. The gas is led into the inner spaces 20 of the filter units 18. The downwardly sloping rocker element 21 elongates the gas downwards towards the lower filter space 22. The gas is led radially outwards into the inner space 20. The gas is then led downwards through the filter material 23. which iodine as methyl iodide is captured from the gas. The gas laminating the filter material 23 is thus purified.
Efter att gasen fleidat igenom filtermaterialet 23 mottas den i ett utvandigt utrymme 25 som är beiaget under filterenheten 18. Det utvandiga utrymmet 25 definieras nedat av en vaggyta 21 hos en nedanfor belagen filterenhet 18. For den fangs ner anordnade filterenheten 18 definieras det utvandiga utrymmet 25 dock av en invandig nedre yta hos behallaren 10. Gasen leds radiellt utat i det utvandiga utrymmet 25 tills den vasentligen kommer 12 kontakt med en invandig yta has behallaren 10. Gasen leds därefter nedat genom flodespassagen 26 dar den successivt blandas med gas frail de vertikalt nedanfOr belagna filterenhetema 18. DA den nedat flodande gasen narmar sig behallarens nedre niva leds den radiellt mat till en position som är belagen nedan- for stoppelementet 15 fdr fordelningsrorets 12 invandiga ande. Gasen leds darefter ut via utloppsroret 14 och utloppsoppningen 13. After the gas has flowed through the filter material 23, it is received in one external space 25 which is occupied under the filter unit 18. The external space 25 is defined at the bottom by a cradle surface 21 of a filter unit 18 located below. For the filter unit 18 arranged below the catch space, however, the external space 25 is defined. of an inner lower surface of the container 10. The gas is guided radially out in the outer space 25 until it essentially arrives 12 contact with an internal surface has the container 10. The gas is then led down through the river passage 26 where it is successively mixed with gas frail the vertically below the coated filter units 18. When the downward flowing gas approaches the lower of the container level, the radial food is guided to a position covered below for the stop element 15 before the inner spirit of the distribution tube 12. The gas is then discharged via the outlet pipe 14 and the outlet opening 13.
