Description
Foreliggende oppfinnelse vedrører en anordning for tettning av en reaktor ved tilslutning av brennere til en sjaktovh, fortrinnsvis ved tilslutning av en plasmagenerator til inn-blåsningsrøret for en sjaktovn, eksempelvis for metall-oksydreduksjon. The present invention relates to a device for sealing a reactor by connecting burners to a shaft furnace, preferably by connecting a plasma generator to the inlet pipe for a shaft furnace, for example for metal oxide reduction.
I svensk søknad nr. 83.04722-5 beskrives en fremgangsmåteA procedure is described in Swedish application no. 83.04722-5
og en anordriing for å bytte ut plasmageneratorer ved uav-brutt drift av en sjaktovnreaktor. and an arrangement for replacing plasma generators during continuous operation of a shaft furnace reactor.
Dette oppnås ved hjelp av en ventil anordnet i reaktor-veggen i tilslutning til dens innblåsningsåpning, hvilken ventil fullstendig avtetter reaktoren mot en omliggende atmosfære når plasmageneratoren er fjernet og som deretter kan åpnes først når plasmageneratoren befinner seg i sin 'tettningstilstand, dvs. med nesen innført i reaktorformens This is achieved by means of a valve arranged in the reactor wall adjacent to its inlet opening, which valve completely seals the reactor against a surrounding atmosphere when the plasma generator is removed and which can then only be opened when the plasma generator is in its 'sealing' state, i.e. with the nose introduced in the reactor form
innblåsningsåpnings tilslutningsdel.inlet connection part.
Ulempen med den ovenfor nevnte teknikk er at under den tid som medgår fra ventilens åpning og til når plasmageneratoren føres fra sin tettningstilstand inn i sin driftstilstand, oppstår det lekkasje i spalten mellom reaktorinnblåsnings-rørets vegg og plasmageneratorens nese. Denne lekkasje kan minimaliseres ved at åpningen i reaktorinnblåsningsrørets tilslutningsdel tilpasses med snever passning i forhold til omkretsen av plasmageneratorens nese. Dette nedsetter lekkasjen noe, men i stedet fører dette til forøkede frém-stillingsomkostninger, samtidig med at innføringen av plasmageneratoren vanskeliggjøres. The disadvantage of the above-mentioned technique is that during the time that elapses from the opening of the valve to when the plasma generator is brought from its sealing state into its operating state, leakage occurs in the gap between the wall of the reactor inlet pipe and the nose of the plasma generator. This leakage can be minimized by fitting the opening in the reactor inlet pipe's connection part with a tight fit in relation to the circumference of the plasma generator's nose. This reduces the leakage somewhat, but instead leads to increased frém position costs, while at the same time making the introduction of the plasma generator more difficult.
Hensikten med foreliggende oppfinnelse er å tilveiebringeThe purpose of the present invention is to provide
en tettningsanordning som helt eliminerer lekkasje under innføring av en brenner i en reaktor under drift, og sær-skildt ved innføring av en plasmagenerator fra dens tettningstilstand når en ventil, som normalt avtetter reaktoren fullstendig fra den omgivende atmosfære, åpnes inntil plasmareaktoren er innført i sin driftstilstand, når denne a sealing device which completely eliminates leakage during the introduction of a burner into a reactor during operation, and in particular when introducing a plasma generator from its sealed state when a valve, which normally seals the reactor completely from the surrounding atmosphere, is opened until the plasma reactor is introduced into its operating condition, when this
! o .11-tetter mot den på reaktoren anordnede tettningsf late.. ! o .11 seals against the sealing surface arranged on the reactor..
iDette oppnås ved tettningsanordningen i henhold til foreliggende oppfinnelse som er særpreget av en i et sete i tilslutning til reaktorinnblåsningsåpningens tilslutningsdel anordnet tettningsring, innbefattende rundt omkretsen for-delte åpninger for tilslutning til én beskyttelsesgasskilde. Ved å anvende en beskyttelsesgass ved et trykk som i det vesentlige er tilnærmet eller overstiger trykket inne i reaktoren, oppnås' at ingen gass fra reaktorens indre kan lekke ut og delvis at reaktorinnblåsningsrørets avslutnings-del kan utføres med generøs tilpasning, hvilket vesentlig letter innføringen og gjør denne raskere. This is achieved by the sealing device according to the present invention, which is characterized by a sealing ring arranged in a seat in connection with the connection part of the reactor inlet opening, including openings distributed around the circumference for connection to one shielding gas source. By using a shielding gas at a pressure which essentially approximates or exceeds the pressure inside the reactor, it is achieved that no gas from the inside of the reactor can leak out and partly that the closing part of the reactor inlet pipe can be made with generous adaptation, which significantly facilitates the introduction and make this one faster.
Ytterligere særpreg og fordeler ved foreliggende oppfinnelse vil fremgå av den etterfølgende beskrivelse i tilslutning til de vedlagte tegninger, hvor Further distinctive features and advantages of the present invention will be apparent from the subsequent description accompanying the attached drawings, where
fig. 1 viser et delsnitt av en tilslutningsdel av et reak-torinnblåsningsrør med en plasmagenerator innført i driftstilstand, og fig. 1 shows a partial section of a connecting part of a reactor inlet pipe with a plasma generator introduced in operating condition, and
fig. 2 viser et forstørret bilde av tetteanordningen i henhold til oppfinnelsen. fig. 2 shows an enlarged image of the sealing device according to the invention.
I fig. 1 vises en plasmagenerator 1 med sin nese 2 innført i driftsstilling i tilslutningsdelen 3 til et reaktorinnblås-ningsrør 4, som er anordnet i en ikke nærmere vist sjaktovn-vegg. Plasmageneratoren føres inn til en tettningstilstand hvor ventilens 5 ventilskive 6 åpner, hvoretter generatoren innføres i den i figuren viste driftstilstand. Herved tetter en fremre flate 7 på plasmageneratoren mot en tetthingsflate 8 på tilslutningsdelens 3 utad vendende side. Fortrinnsvis er det også anordnet en form for tettningsanordning mellom de to flater. In fig. 1 shows a plasma generator 1 with its nozzle 2 inserted into the operating position in the connection part 3 of a reactor blow-in pipe 4, which is arranged in a shaft furnace wall, not shown in detail. The plasma generator is brought into a sealing state where the valve disc 6 of the valve 5 opens, after which the generator is brought into the operating state shown in the figure. Hereby, a front surface 7 of the plasma generator seals against a sealing surface 8 on the outward facing side of the connection part 3. Preferably, some form of sealing device is also arranged between the two surfaces.
Tettningsanordnirigen i henhold til oppfinnelsen, som er vist i større skala i fig. 2, innbefatter en flens 9 med en kanal 10 for tilførsel av en eller annen beskyttelsesgass. I flen-sen 9 er anordnet et sete 12 for en indre tettningsring 13.' Tettningsringen 13 holdes på plass av en låsering 14 som' The sealing device according to the invention, which is shown on a larger scale in fig. 2, includes a flange 9 with a channel 10 for the supply of some protective gas. A seat 12 for an inner sealing ring 13 is arranged in the flange 9. The sealing ring 13 is held in place by a locking ring 14 which
I IN
holdes på plass ved hjelp av bolter, slik som antydet med stiplede linjer ved 15. På denne måte lettes byttet av tettningsringen 13. I fig. 2 vises også en O-ringtettning 16 som tilveiebringer tettning mellom plasmageneratoren og tetteflaten. is held in place by means of bolts, as indicated by dashed lines at 15. In this way, the replacement of the sealing ring 13 is facilitated. In fig. 2 also shows an O-ring seal 16 which provides a seal between the plasma generator and the sealing surface.
Tettningsringen 13 utviser et innad vendende spor 17 med åpninger 18 som kommuniserer med det innenfor tettningsringen 13 liggende ringformede rom 19, som tilføres beskyttelsesgass gjennom den ovenfor nevnte kanal 10. The sealing ring 13 exhibits an inwardly facing groove 17 with openings 18 which communicate with the annular space 19 lying within the sealing ring 13, which is supplied with shielding gas through the aforementioned channel 10.
Ved den konstruktive utformning i henhold til foreliggende By the constructive design according to the present
oppfinnelse kan passningen mellom reaktorinnblåsningsrørets tilslutningsdel 3 og plasmageneratoren gjøres generøs, idet selve tetteringen 13 kan utformes med en diameter som er i nær overensstemmelse med omkretsen for plasmageneratorens hese. Tettningsringen 13 kan utføres i metall (rødmetall) slik at den ikke skades av sot- og slaggavsetninger på generatornesen ved uttrekkning av generatoren. invention, the fit between the reactor inlet pipe's connection part 3 and the plasma generator can be made generous, as the sealing ring 13 itself can be designed with a diameter that is in close agreement with the circumference of the plasma generator's throat. The sealing ring 13 can be made of metal (red metal) so that it is not damaged by soot and slag deposits on the generator nose when the generator is pulled out.
I henhold til en foretrukken utførelsesform av oppfinnelsen er tettningsringen 13 utformet i det minste i en viss ut-strekning av et ettergivende materiale med lav friksjons-koeffisient, eksempelvis "teflon". Ved å utforme tettningsringen med en utvidet innløpsende 20 lettes tilslutningen av plasmageneratoren ytterligere. According to a preferred embodiment of the invention, the sealing ring 13 is formed, at least to a certain extent, of a yielding material with a low coefficient of friction, for example "teflon". By designing the sealing ring with an extended inlet end 20, the connection of the plasma generator is further facilitated.
Eksempler på egnede beskyttelsesgasser er i denne forbind-else nitrogengass og argon. Examples of suitable protective gases in this connection are nitrogen gas and argon.
Med tetteanordningen i henhold til oppfinnelsen oppnås så-ledes at en utlekkning fra reaktoren under plasmageneratorens tilslutning i det vesentlige fullstendig forhindres. I stedet vil beskyttelsesgassen strømme ut og også i en viss grad inn i reaktoren. Innstrømningen i reaktoren kan imidlertid minimaliseres ved nøye å tilpasse beskyttelsesgassens trykk, slik at den kun i liten grad overstiger det trykk som hersker i reaktoren. With the sealing device according to the invention, it is thus achieved that leakage from the reactor during the connection of the plasma generator is essentially completely prevented. Instead, the shielding gas will flow out and also to some extent into the reactor. However, the inflow into the reactor can be minimized by carefully adjusting the pressure of the shielding gas, so that it only slightly exceeds the pressure prevailing in the reactor.
