The blocks (12) are located upon at least one essentially horizontal grating (11) between an inlet to the reactor chamber and an outlet from said chamber. The grating (11) is vertically displaceable between the walls (10) of the chamber. The displaceability is damped by means of resilient means (14). <IMAGE>

Description

502 474 10 15 20 25 30 35 2 block som står längst bort fràn fjäderanordningen bara pàverkas av ett ringa tryck. Det kan vidare vara mycket svårt att komma àt anordningarna frán utsidan, eftersom reaktorerna ofta monteras tätt intill tvá eller tre väggar. 502 474 10 15 20 25 30 35 2 blocks which are furthest from the spring device are only affected by a small pressure. Furthermore, it can be very difficult to access the devices from the outside, as the reactors are often mounted close to two or three walls.

Detta innebär att de keramiska block som befinner sig närmast de sidoytor som bildar stödytor för blocken kommer att utsättas för' betydligt: mer slitage än de block som befinner sig närmast fjäderorganen.This means that the ceramic blocks which are closest to the side surfaces which form support surfaces for the blocks will be exposed to 'significantly more wear than the blocks which are closest to the spring means.

Hittills har man varit tvungen att vidtaga kostnadskrävande åtgärder för att isolera katalysatorreaktorkammaren fràn de stomvibrationer som normalt förekommer vid stora Diesel- motorer pà fartyg. i TEKNISKA PROBLEMET Ändamålet med föreliggande uppfinning är att åstadkomma ett förbättrat upplag för monolitblock inuti en katalysator- reaktorkammare, så att det mekaniska slitaget pá monolit- blocken reduceras, utan att komplicerade vibrationsdämpande anordningar fordras vid reaktorkammaren.Until now, costly measures have had to be taken to isolate the catalyst reactor chamber from the body vibrations that normally occur with large diesel engines on ships. IN THE TECHNICAL PROBLEM The object of the present invention is to provide an improved support for monolith blocks inside a catalyst reactor chamber, so that the mechanical wear on the monolith blocks is reduced, without requiring complicated vibration damping devices at the reactor chamber.

LÖSNINGEN För detta ändamål kännetecknas uppfinningen av att galler- planet är förskjutbart i vertikalled mellan kammarens väggar, och att förskjutbarheten är dämpad medelst fjäder- organ.THE SOLUTION For this purpose, the invention is characterized in that the grid plane is displaceable in the vertical direction between the walls of the chamber, and that the displaceability is damped by means of spring means.

Enligt en fördelaktig variant av uppfinningen är flera monolitblock monterade i en gemensam stödram av metall, som distanserar den sköra blockytan från direkt anliggning mot gallerplanet.According to an advantageous variant of the invention, several monolith blocks are mounted in a common support frame of metal, which distances the fragile block surface from direct abutment against the grid plane.

BESKRIVNING AV RITNINGARNA Uppfinningen kommer nedan att beskrivas med hänvisning till utföringsexempel som visas pà de bifogade ritningarna, pà vilka lO 15 20 25 30 35 '502 474 3 .DESCRIPTION OF THE DRAWINGS The invention will be described below with reference to exemplary embodiments shown in the accompanying drawings, in which 10 15 20 25 30 35 '502 474 3.

Fig. 1 är ett schematiskt vertikalsnitt genom en reaktorkammare' med ett upplag enligt ett första utföringsexempel av uppfinningen, Fig. 2 är ett motsvarande snitt genom ett upplag enligt ett andra utförande av uppfinningen, och Fig. 3 visar pà motsvarande sätt som Fig. 1 och 2 ett tredje utförande av uppfinningen.Fig. 1 is a schematic vertical section through a reactor chamber with a support according to a first embodiment of the invention, Fig. 2 is a corresponding section through a support according to a second embodiment of the invention, and Fig. 3 shows in a corresponding manner as Fig. 1 and 2 a third embodiment of the invention.

BESKRIVNING AV UTFÖRINGSEXEMPEL En katalysatorreaktorkammare har normalt en avlàng form med ett fyrkantigt tvärsnitt, och monteras vertikalt, t.ex. i ett fartyg för rening av avgaser frán en eller flera Dieselmotorer.DESCRIPTION OF EMBODIMENTS A catalyst reactor chamber normally has an elongated shape with a square cross-section, and is mounted vertically, e.g. in a ship for the purification of exhaust gases from one or more Diesel engines.

Kammarens inre är avskärmat gentemot omgivningen medelst sidoväggar 10. Invändigt är kammaren försedd med gallerplan ll i bildar stöd för hàlkroppsmonoliter 12 av keramiskt material, vilka medverkar flera våningar. Gallerplanen till att reducera exempelvis kväveoxidhalterna i avgaserna.The interior of the chamber is shielded from the surroundings by means of side walls 10. Inside, the chamber is provided with grid planes 11 in the form of support for hollow body monoliths 12 of ceramic material, which have several floors. The grid plan to reduce, for example, the nitrogen oxide contents in the exhaust gases.

Varje hàlkroppsmonolit är försedd med en strumpa 13 som sträcker sig längs de vertikala sidorna och bildar tätning mot de intill befintliga blocken samt sidoväggarna 10.Each hollow body monolith is provided with a sock 13 which extends along the vertical sides and forms a seal against the adjacent blocks and the side walls 10.

Varje gallerplan ll är monterat så att det är förskjutbart i vertikalled mellan kammarens väggar ll, och förskjutbar- heten är dämpad medelst fjäderorgan 14. Detta àstadkommes enligt medelst en upplagskudde 14 av fjädrande material, som gör det möjligt för gallerplanen med monolitblocken 12 att vertikalled i förhållande till röra sig 'något i reaktorväggarna.Each grid plane 11 is mounted so that it is displaceable vertically between the walls 11 of the chamber, and the displaceability is damped by means of spring means 14. This is achieved by means of a support cushion 14 of resilient material, which enables the grid plane with monolith blocks 12 to relation to move 'slightly in the reactor walls.

Genom denna rörlighet i vertikalled kan reaktorkammaren vibrera eller svänga i vertikalled, utan att dessa rörelser förmedlas direkt till monolitblocken, vilka i. princip är lagrade "flytande" via gallerplanens upplagskuddar 14. 10 15 20 25 30 35 E02 474 4 I utföringsexemplet enligt Fig. 1 är upplaget 14 utfört, så att det fixeras inuti ett nischparti 15 av kammarväggen 10, och skjuter in ett stycke i kammaren med upplagsytor för gallerplanet ll. Dessutom har gallerplanet stöd i sidled av den fjädrande upplagskudden 14.Due to this vertical movement, the reactor chamber can vibrate or pivot vertically, without these movements being transmitted directly to the monolith blocks, which are in principle stored "floating" via the grid planes' support pads 14. In the exemplary embodiment according to FIG. 1, the support 14 is designed so that it is fixed inside a niche portion 15 of the chamber wall 10, and projects a piece into the chamber with support surfaces for the grid plane 11. In addition, the grid plane has lateral support of the resilient support cushion 14.

Fig. 2 visar ett alternativt utföringsexempel, vid vilket gallerplanet 11 inte, såsom i det i Fig. 1 visade utförings- exemplet, bara vilar pà upplagskudden 14, utan via en list 16 är inklämt mellan två kuddar 14 som tar upp rörelser både i horisontal- och vertikalled.Fig. 2 shows an alternative embodiment, in which the grid plane 11 does not, as in the exemplary embodiment shown in Fig. 1, only rest on the support cushion 14, but via a strip 16 is sandwiched between two cushions 14 which take up movements both horizontally and vertical joint.

Fig. 3 visar ytterligare ett alternativt utföringsexempel, vid vilket monolitblocken 12 är monterade i en eller flera grupper, t.ex. fyra och fyra, och avtätade medelst en formstabil stödram 17 som i sin tur vilar pà gallerplanet 11. Stödramen 17 är utformad som en làdkonstruktion i tunn rostfri plåt med fyra sidor som är öppen uppåt och nedåt.Fig. 3 shows a further alternative embodiment, in which the monolith blocks 12 are mounted in one or more groups, e.g. four and four, and sealed by means of a dimensionally stable support frame 17 which in turn rests on the grid plane 11. The support frame 17 is designed as a drawer construction in thin stainless steel sheet with four sides which are open upwards and downwards.

Ett smalt kantparti 18 är vikt 90° in mot blockens undersida och utgör enda anliggningsytan mot gallerplanet. Stödramen 17 är elastiskt tätande monterad medelst tunna packningar 19 av värmeexpanderande material, dels mellan stödramen och stödramen och reaktorväggen 10, och dels mellan monolitblocken.A narrow edge portion 18 is folded 90 ° towards the underside of the blocks and constitutes the only abutment surface against the grid plane. The support frame 17 is elastically sealingly mounted by means of thin gaskets 19 of heat-expanding material, partly between the support frame and the support frame and the reactor wall 10, and partly between the monolith blocks.

Gallerplanet är försett med ett längs ytterkanten löpande, i tvärsnitt som en stympad kon utåt divergerande kantparti 20, vilket griper in i ett utàt V-format parti 21 av reaktorväggen 10. Ett utrymme mellan kantpartiet 20 och väggpartiet 21 upptar den fjädrande upplagskudden 14.The grid plane is provided with a diverging edge portion 20 running along the outer edge, in cross section as a truncated cone, which engages in an outwardly V-shaped portion 21 of the reactor wall 10. A space between the edge portion 20 and the wall portion 21 receives the resilient support cushion 14.

Upplagskudden 14 är lämpligen framställd av rostfri stáltråd som formats genom "filtning“ och pressning till en elastisk kudde, vilken uppvisar en progressiv fjäderkonstant. Kudden bildar en isolator som tål mycket höga temperaturer och är àldringsbeständig. '502 474 5 V Uppfinningen är ej begränsad till det ovan beskrivna utföringsexemplet, utan flera* varianter är tänkbara inom ramen för efterföljande krav. Exempelvis kan gallerplanens ll infästning gentemot kammarväggarna via upplag ske pá många olika sätt.The support cushion 14 is suitably made of stainless steel wire formed by "felting" and pressing into an elastic cushion which has a progressive spring constant. The cushion forms an insulator which can withstand very high temperatures and is age-resistant. The invention is not limited to the embodiment described above, without several * variants are conceivable within the scope of the following claims, for example the attachment of the grid plane 11 to the chamber walls via storage can take place in many different ways.
