Description
Den foreliggende oppfinnelse vedrører en varmeveksler. The present invention relates to a heat exchanger.
Mere spesielt vedrører den foreliggende oppfinnelse en varmeveksler for hurtig avkjøling av høytemperaturgass. More particularly, the present invention relates to a heat exchanger for rapid cooling of high-temperature gas.
Mere spesielt vedrører den foreliggende oppfinnelse en varmeveksler for avkjøling av syntesegass (syn-gass) som kommer fra den katalytiske delvise oksydasjon av lette hydrokar-boner, f.eks. metan, kjent som "Catalytic Partial Oxidation" More particularly, the present invention relates to a heat exchanger for cooling synthesis gas (syn gas) which comes from the catalytic partial oxidation of light hydrocarbons, e.g. methane, known as "Catalytic Partial Oxidation"
(CPO). (CPO).
Det er kjent at fremstillingen av syn-gass, en gassholdig blanding som inneholder H2og CO i forskjellige mengdean-deler, kan gjennomføres ved den katalytiske delvise oksydasjon av naturgass, metan eller gassholdige/flytende hydrokar-bonblandinger fra raffinerier eller petrokjemiske fasili-teter, i tubulasre reaktorer med stasjonært sjikt som kan virke, avhengig av den anvendte katalysatoren, ved et trykk som varierer fra 1 til 150 atm og temperaturer som er høyere enn 500°C som, i noen tilfeller, kan nå og overskride 1000°C. It is known that the production of syn gas, a gaseous mixture containing H2 and CO in different proportions, can be carried out by the catalytic partial oxidation of natural gas, methane or gaseous/liquid hydrocarbon mixtures from refineries or petrochemical facilities, in tubular fixed bed reactors that can operate, depending on the catalyst used, at pressures varying from 1 to 150 atm and temperatures higher than 500°C which, in some cases, can reach and exceed 1000°C.
Den raske avkjølingen av syn-gass i utløpet av reaksjonsenheten er en nødvendighet som ikke må glemmes da, dersom denne gassen holdes ved disse temperaturer, selv for kortere tidsperioder, kan den gi uønskede biprodukter slik som alko-holer eller olefiner (i alt vesentlig etylen og propylen) eller kan til og med regenerere utgangsmetanet. Systemer for hurtig avkjøling av en gass som har en høy temperatur er nevnt i litteraturen, i f.eks. patentene US 2 896 927 og US 4 377 132 eller i "Syngas Cooler Systems for Gasification Plants", en ALSTOM brosjyre. Enkelte metoder og relevant utstyr inkluderer den direkte avkjøling av gass ved hjelp av vann (bråkjøling). Denne løsning har imidlertid den ulempen at den avkjølte syn-gassen må separeres fra den dannede vann-holdige dampen. The rapid cooling of syn-gas at the outlet of the reaction unit is a necessity that must not be forgotten because, if this gas is kept at these temperatures, even for shorter periods of time, it can give unwanted by-products such as alcohols or olefins (mainly ethylene and propylene) or can even regenerate the starting methane. Systems for rapid cooling of a gas that has a high temperature are mentioned in the literature, in e.g. patents US 2,896,927 and US 4,377,132 or in "Syngas Cooler Systems for Gasification Plants", an ALSTOM brochure. Certain methods and relevant equipment include the direct cooling of gas using water (quenching). However, this solution has the disadvantage that the cooled syn-gas must be separated from the formed water-containing steam.
Andre industrielle systemer består av utstyr for indirekte avkjøling som tillater utvinning av varme inneholdt i syn- gass for produksjon av høytrykksdamp, se for eksempel US 3788281 A. Other industrial systems consist of equipment for indirect cooling which allows the extraction of heat contained in syngas for the production of high-pressure steam, see for example US 3788281 A.
Formålet med den foreliggende oppfinnelse er en innretning for den effektive og hurtige indirekte avkjøling av syn-gass i anvendelser hvori den termiske utvinning av den frie varmen i gassen ikke er nødvendig for teknisk forenkling eller av økonomiske årsaker, f.eks. ved produksjon av hydrogen i medium skala eller små-skala systemer. The purpose of the present invention is a device for the efficient and rapid indirect cooling of syn gas in applications in which the thermal extraction of the free heat in the gas is not necessary for technical simplification or for economic reasons, e.g. in the production of hydrogen in medium-scale or small-scale systems.
Man har derfor funnet en varmeveksler som er særlig egnet for den hurtige avkjøling av gasser som er ved en temperatur som er høyere enn 500°C, f.eks. mellom 750 og 1100°C, og som gjør det mulig å unngå enhver kontakt mellom den varme gassen og kjølevæsken, normalt vann. A heat exchanger has therefore been found which is particularly suitable for the rapid cooling of gases which are at a temperature higher than 500°C, e.g. between 750 and 1100°C, and which makes it possible to avoid any contact between the hot gas and the coolant, normally water.
Formålet med den foreliggende oppfinnelse vedrører derfor en varmeveksler ifølge krav 1 for hurtig avkjøling av en gass ved høy temperatur som forlater en reaktorenhet/innretning, som omfatter et koblingselement til The purpose of the present invention therefore relates to a heat exchanger according to claim 1 for rapid cooling of a gas at a high temperature leaving a reactor unit/device, which comprises a connecting element to
reaksjonsenheten/innretningen, en gassavkjølingsrørledning og gasstransportrørledning og en dekkmantel, hvori: the reaction unit/facility, a gas cooling pipeline and gas transport pipeline and a cover jacket, in which:
a) koblingselementet som er i alt vesentlig sylindrisk er plassert mellom reaksjonsenheten og varmevekslermantelen, det avkjøles internt ved hjelp av et kjølefluid, normalt vann, og er aksialt forbundet ved hjelp av en gjennomløpskanal til tilførselsledningen for den varme gassen som kommer fra reaksjonsenheten; b) transportrørledningen og avkjølingsrørledningen for den varme gassen er festet til basisen av koblingselementet a) the coupling element which is essentially cylindrical is located between the reaction unit and the heat exchanger jacket, it is cooled internally by means of a cooling fluid, normally water, and is axially connected by means of a through channel to the supply line for the hot gas coming from the reaction unit; b) the transport pipeline and the cooling pipeline for the hot gas are attached to the base of the coupling element
som er forbundet med reaksjonsenheten ved gjennomløps-kanalen, idet nevnte transportrørledning og avkjøl-ingsrørledning for den varme gassen består av to which is connected to the reaction unit by the flow channel, as said transport pipeline and cooling pipeline for the hot gas consist of two
seksjoner: sections:
-den første seksjon som er i alt vesentlig lineær er innført i en koaksial posisjon i en andre rørledning som har en større diameter som mantler den for å danne et ringformet hulrom hvori kjølefluidet, normalt vann, strømmer, idet en ende av nevnte første seksjon danner - the first section which is substantially linear is inserted in a coaxial position in a second pipeline having a larger diameter which sheaths it to form an annular cavity in which the cooling fluid, normally water, flows, one end of said first section forming
gjennomløpskanalen i koblingselementet; the through channel in the coupling element;
-den andre seksjon som er festet på en kontinuerlig måte til den første seksjon i den andre enden og er i alt vesentlig krummet i en halvsirkel, omslutter spiralt, uten berøring derav, i det minste noe av nevnte første -the second section which is attached in a continuous manner to the first section at the other end and is substantially curved in a semicircle, spirally enclosing, without touching thereof, at least some of said first
mantlede seksjon; mantled section;
c)dekkmantelen som er i alt vesentlig sylindrisk og er lukket i en ende og åpen i den andre enden, er forbundet til c) the cover, which is essentially cylindrical and is closed at one end and open at the other end, is connected to
nevnte koblingselement og omfatter i det minste åpninger for å avgi kjølevassken og den avkjølte gassen. said connecting element and comprises at least openings to discharge the cooling liquid and the cooled gas.
Særlige utførelsesformer av oppfinnelsen en angitt i kravene 2-8. Particular embodiments of the invention are set out in claims 2-8.
I følge den foreliggende oppfinnelse er koblingselementet aksialt krysset ved gjennomløpskanalen, forbundet med reak-sjonsinnretningen, f.eks. en CPO reaktor for fremstilling av syn-gass ved en temperatur fra 500 til 1100°C. According to the present invention, the coupling element is axially crossed at the through channel, connected to the reaction device, e.g. a CPO reactor for the production of syn gas at a temperature from 500 to 1100°C.
Den eksterne rørledning som dekker den første seksjon av transportrørledningen for den varme gassen er forbundet, i en ende, med en eller flere spesifikke tilførselskanaler av kjølevæsken, som passerer gjennom koblingselementet. Koblingselementet blir dessuten uavhengig avkjølt ved hjelp av en kanal som tilfører kjølevæsken i overensstemmelse med dets akse. Nevnte fluid fjernes fra elementet etter å ha fulgt en spiralvei fra innsiden og utover, ved hjelp av en åpning som er forbundet med sideoverflaten til selve elementet. The external pipeline covering the first section of the transport pipeline for the hot gas is connected, at one end, with one or more specific supply channels of the cooling liquid, which pass through the coupling element. The coupling element is also independently cooled by means of a channel which supplies the coolant in accordance with its axis. Said fluid is removed from the element after following a spiral path from the inside outwards, by means of an opening which is connected to the side surface of the element itself.
I en alternativ utførelsesform av den foreliggende oppfinnelse kan kjølefluid som sirkulerer inne i koblingselementet for uavhengig avkjøling fjernes inne i volumet inneholdt i mantelen til varmeveksleren. In an alternative embodiment of the present invention, cooling fluid circulating inside the coupling element for independent cooling can be removed inside the volume contained in the jacket of the heat exchanger.
Den andre enden av den andre rørledningen som dekker den første seksjonen er fri og ender i den krummede seksjonen, i alt vesentlig i en halvsirkel, slik at kjølevæsken fritt kan munne ut, men i den motsatte retningen, i det lukkede rommet av mantelen, etter strømning i kappen mellom de to rørled-ninger . The other end of the second pipeline covering the first section is free and terminates in the curved section, essentially in a semi-circle, so that the coolant can freely exit, but in the opposite direction, in the closed space of the jacket, after flow in the jacket between the two pipelines.
Væskens vei inne i mantelvolumet ledes ved hjelp av ledeplater som er ortogonale på aksen, som også virker som en bærer for begge seksjoner av gasstransportrørledningen. The path of the fluid inside the mantle volume is guided by means of guide plates orthogonal to the axis, which also act as a carrier for both sections of the gas transport pipeline.
Den andre seksjonen av transportrørledningene og kjøle-rørledningen er i alt vesentlig kontinuerlig med den første seksjonen, uten avbrudd, og utvikler seg i en spiral. For å spare plass vil spiralene foretrukket omslutte, uten berøring derav, den første delen av den dekkede rørledning. Det er imidlertid mulig at spiralene kan utvikle seg nedstrøms av den første seksjon. The second section of the transport pipelines and the cooling pipeline is substantially continuous with the first section, without interruption, and develops in a spiral. In order to save space, the spirals will preferably enclose, without touching it, the first part of the covered pipeline. However, it is possible that the spirals may develop downstream of the first section.
Den andre enden av transportrørledningen, dvs. enden av spiralseksjonen, er forbundet med en åpning som er tilstede på mantelen for fjerning av den avkjølte gassen utenfor varmeveksleren, som er formålet med den foreliggende oppfinnelse. The other end of the transport pipeline, i.e. the end of the spiral section, is connected to an opening present on the jacket for the removal of the cooled gas outside the heat exchanger, which is the object of the present invention.
Mantelen har en i alt vesentlig sylindrisk form hvor diameteren til basisen i alt vesentlig er identisk med den til koblingselementet og større enn diameteren til spiralene. På denne måten inkluderer mantelen i sitt indre rom, rørled-ningssystemet for første og andre seksjon. Rommet i mantelen fylles med kjølefluidet, som fjernes ved hjelp av varmeveksleren gjennom en passende tømme-åpning. I en alternativ ut-førelsesf orm av den foreliggende oppfinnelse vil den sirku-lerende væsken som også er bestemt for avkjølingen av koblingselementet også samle seg i mantelrommet. Den totale væsken fjernes fra varmeveksleren, som er formålet med den foreliggende oppfinnelse, gjennom den korrekte åpning som er plassert på mantelen. Uansett, enten man opererer med den første eller andre alternative utførelsesform, er rørled-ningssystemet i første og andre seksjon fullstendig nedsenket i kjølevæsken. The mantle has an essentially cylindrical shape where the diameter of the base is essentially identical to that of the connecting element and larger than the diameter of the spirals. In this way, the mantle includes in its inner space the piping system for the first and second sections. The space in the jacket is filled with the cooling fluid, which is removed by means of the heat exchanger through a suitable drain opening. In an alternative embodiment of the present invention, the circulating liquid which is also intended for the cooling of the coupling element will also collect in the jacket space. The total liquid is removed from the heat exchanger, which is the object of the present invention, through the correct opening placed on the jacket. In any case, whether one operates with the first or second alternative embodiment, the piping system in the first and second sections is completely immersed in the coolant.

fig. 2 representerer et plant frontsnitt av den skjematiske fremstillingen i fig. 1, dannet i henhold til seksjonen ZZ. fig. 2 represents a planar front section of the schematic representation in fig. 1, formed according to section ZZ.
Under henvisning til figurene omfatter varmeveksleren som er formålet med den foreliggende oppfinnelse, koblingselementet A, rørledningssystemet for gasstransporten og gassavkjølingen B og mantelen C. With reference to the figures, the heat exchanger which is the object of the present invention comprises the coupling element A, the pipeline system for gas transport and gas cooling B and the jacket C.
Koblingselementet A inkluderer også kanalene 1 og 2 for til-førsel av kjølefluidet (vann), som samler seg i den koaksiale kanalen 7, og kjølekanalen 4, for den uavhengige avkjøling av koblingselementet, som tilfører vannet til sentrum av spiral-en 4' hvorfra det strømmer ut igjennom 5. The coupling element A also includes the channels 1 and 2 for the supply of the cooling fluid (water), which collects in the coaxial channel 7, and the cooling channel 4, for the independent cooling of the coupling element, which supplies the water to the center of the spiral 4' from which it flows out through 5.
Rørledningssystemet B for gasstransport og gassavkjøling omfatter den første rørledningsseksjon 6, den koaksiale rørledningen som mantler den 7 og den andre seksjonen av spiralrørledningen 8. Den første seksjon av rørledningen 6 inkluderer i sin tur den første enden 3, som sammenfaller med den aksiale gjennomløpskanalen til elementet A, og den andre krumlinjede enden 3'. Den koaksiale rørledningen 7 mantler den første seksjonen som starter fra enden 3 inntil den krumme enden 3'. I denne enden (3') er den koaksiale rørledning ikke lukket slik at vannet kan fjernes inne i mantelen, som vil bli beskrevet senere. The pipeline system B for gas transport and gas cooling comprises the first pipeline section 6, the coaxial pipeline that sheaths it 7 and the second section of the spiral pipeline 8. The first section of the pipeline 6 in turn includes the first end 3, which coincides with the axial passage channel of the element A, and the other curved end 3'. The coaxial pipeline 7 sheaths the first section starting from the end 3 until the curved end 3'. At this end (3'), the coaxial pipeline is not closed so that the water can be removed inside the jacket, which will be described later.
Mantelen C inkluderer utløpsåpningen 9 for den avkjølte gassen, utløpsåpningen 10 for vannet og de bærende ledeplater 11 i de to seksjonene til gasstransportrørledningen. The mantle C includes the outlet opening 9 for the cooled gas, the outlet opening 10 for the water and the supporting guide plates 11 in the two sections of the gas transport pipeline.

Spesielt blir den varme gassen 12 som forlater reaksjonsenheten (ikke vist) innført i varmeveksleren ved hjelp av gjennomløpskanalen 3 i koblingselement A. Gassen strømmer inn i den første seksjonen 6 av avkjølings- og transportrørledningen B og deretter inn i den andre seksjonen 8, for deretter å bli fjernet ved lav temperatur gjennom utløpsåpningene for gassen 9. Når gassen strømmer gjennom den første seksjonen 6 gjennomgår den en første hurtige avkjøling ved hjelp av vannet, tilført gjennom 1 og 2, som sirkulerer inne i det ringformede hulrommet mellom rørledningene 6 og 7, opp til enden 3'. Her strømmer vannet fritt i det lukkede rommet til mantelen, fyller det, det avkjøler gassen ytterligere som strømmer gjennom seksjonen 8 av kjølerøret og fjernes fra åpningen 10. The operation of the heat exchanger which is the purpose of the present invention will appear on the basis of the drawings and what is described above. In particular, the hot gas 12 leaving the reaction unit (not shown) is introduced into the heat exchanger by means of the flow channel 3 in the coupling element A. The gas flows into the first section 6 of the cooling and transport pipeline B and then into the second section 8, and then to be removed at low temperature through the outlet openings for the gas 9. When the gas flows through the first section 6, it undergoes a first rapid cooling by means of the water, supplied through 1 and 2, which circulates inside the annular cavity between the pipelines 6 and 7, up to the end 3'. Here the water flows freely in the closed space of the mantle, filling it, it further cools the gas which flows through the section 8 of the cooling pipe and is removed from the opening 10.
Ved drift, for å forhindre overoppheting av During operation, to prevent overheating of
koblingselementet, avkjøles det sistnevnte ved hjelp av det spesifikke systemet som består av kanalen 4 som tilfører vann til systemet 4' som utvikler seg i en spiral, og av tømmekanalen 5. the coupling element, the latter is cooled by means of the specific system consisting of the channel 4 that supplies water to the system 4' which develops in a spiral, and of the discharge channel 5.
