Description
Denne oppfinnelse vedrører en varmeveksler for strømmende medier. This invention relates to a heat exchanger for flowing media.
Varmevekslere er tidligere kjent i forskjellige utførelser. Rørvarmeveksler omfatter vanligvis en eller flere bunter med Heat exchangers are previously known in various designs. Tube heat exchangers usually comprise one or more bundles of
rør som ved endene er innvalset eller innsveiset i rørveksle-rens endeplater. Slike varmevekslere er forholdsvis kostbare i fremstilling og de er også vanskelige å vedlikeholde og reparere. Varmeplateveksler er også tidligere kjent i forskjellige utfor-minger. Felles for de fleste av dem er at de krever mange tet-ninger og er lett utsatt for lekkasjer. pipes whose ends are rolled or welded into the end plates of the pipe exchanger. Such heat exchangers are relatively expensive to manufacture and they are also difficult to maintain and repair. Heat plate exchangers are also previously known in various designs. What most of them have in common is that they require many seals and are easily exposed to leaks.
Hensikten med oppfinnelsen er å tilveiebringe en varmeveksler som består av få robuste deler som er lett å montere og lett å ta fra hverandre, og hvor de enkelte deler er lett å skifte ut om nødvendig. En annen hensikt med oppfinnelsen er å tilveiebringe en varmeveksler med liten bredde og lengde j forhold til varmeutvekslingsflatens størrelse og den oppnådde virkningsgrad. Disse hensikter er oppnåes ved at det er tilveiebragt en varmeveksler som utmerker seg ved de i patentkravene angitte trekk. The purpose of the invention is to provide a heat exchanger which consists of a few robust parts which are easy to assemble and easy to take apart, and where the individual parts are easy to replace if necessary. Another purpose of the invention is to provide a heat exchanger with a small width and length in relation to the size of the heat exchange surface and the achieved efficiency. These purposes are achieved by providing a heat exchanger which is distinguished by the features stated in the patent claims.
I en varmeveksler ifølge oppfinnelsen føres mediet som skal oppvarmes, frem og tilbake langs en dobbeltskrue i mellomrommet mellom varmevekslerens heteflaterør og de utfører bare en 180° ven-ding under passeringen av varmeveksleren, slik at trykkfallet blir forholdsvis lite og dermed den energi som kreves til pum-ping tilsvarende mindre. Det er også en fordel ved utførelsen ifølge oppfinnelsen at konstruksjonen krever forholdsvis liten grad av presisjon og derved kan produseres rimeligere. In a heat exchanger according to the invention, the medium to be heated is fed back and forth along a double screw in the space between the heat exchanger's hot surface tubes and they only perform a 180° turn during the passage of the heat exchanger, so that the pressure drop is relatively small and thus the energy required to pum-ping correspondingly less. It is also an advantage of the embodiment according to the invention that the construction requires a relatively small degree of precision and can thereby be produced more cheaply.
Oppfinnelsen skal forklares nærmere nedenfor ved hjelp av et eksempel og under henvisning til tegningen som viser et leng-desnitt gjennom en varmeveksler ifølge oppfinnelsen. Varmeveksleren kan brukes til oppvarming/kjøling av forskjellige medier, men i eksempeltilfellet antas at den tjener til oppvarming av vann ved hjelp av damp. Tegningen viser en horisontal utførelse av varmeveksleren, men den kan like godt være utført vertikal. The invention will be explained in more detail below by means of an example and with reference to the drawing which shows a longitudinal section through a heat exchanger according to the invention. The heat exchanger can be used for heating/cooling different media, but in the example case it is assumed that it serves to heat water using steam. The drawing shows a horizontal design of the heat exchanger, but it could just as easily be designed vertically.
Varmeveksleren omfatter et sylindrisk hus 1 med en vegg 2 The heat exchanger comprises a cylindrical housing 1 with a wall 2
og en bunn 3. Husets ene ende 4 er åpent og avsluttet med en ytre flensring 5. Huset 1 er fortrinnsvis anbragt i en isola-sjonskappe 6 med isolasjonsmateriale 7. Husets vegg 2 er forsynt med en utløpsstuss 8, i dette tilfelle for dampkondensat. and a bottom 3. One end 4 of the housing is open and finished with an outer flange ring 5. The housing 1 is preferably placed in an insulation jacket 6 with insulating material 7. The wall 2 of the housing is provided with an outlet connection 8, in this case for steam condensate.
Videre er huset forsynt met et støtteben eller braketter 9. Furthermore, the housing is provided with a support leg or brackets 9.
Koaksialt i huset 1 er det anordnet en rørinnsats 10 omfattende to i hverandre anordnede rør hvorav det ytre rør er betegnet med 11 og ved sin ene ende er forsynt med en ytre flensring 12 like stor som husets flensring 5 og ved sin andre ende med en indre flensring 13 med en åpning 14. Ytterrørets 11 diameter er vesentlig mindre enn husets 1. Det er også betydelig avstand mellom rørets flens 13 og husets bunn 3. Coaxially in the housing 1, there is arranged a pipe insert 10 comprising two nested pipes, of which the outer pipe is denoted by 11 and is provided at one end with an outer flange ring 12 the same size as the housing's flange ring 5 and at its other end with an inner flange ring 13 with an opening 14. The diameter of the outer pipe 11 is significantly smaller than that of the housing 1. There is also a considerable distance between the pipe's flange 13 and the bottom 3 of the housing.
Koaksialt med ytterrøret 11 er det i dette anordnet et nes-ten like langt innerrør 15 med vesentlig mindre diameter enn yt-terrørets. Ved sin ene ende bærer innerrøret 15 en blindflens 16 med like stor ytterdiameter som av husets 1 flensring 5. Ved sin andre ende bærer innerrøret 15 en ytre flensring 17 med noe mindre ytterdiameter enn ytterrørets 11 innerdiameter. Denne ende av røret er åpen og i flukt med flensåpningen 14 i ytterrø-ret. Rørenes 11,15 lengde er avpasset slik at flensringene 13, 17 ligger an mot hverandre når rørenes flenser 12,16 er i anlegg med hverandre. På innerrøret 15 er det festet to skrueformede platevegger eller vinger 18 hhv. 19 som mellom seg danner to kontinuerlige, skrueformede passasjer 20 hhv. 21. Plateveggene 18,19 er fast forbundet med innerrøret 15 og har en ytterdiameter som passer til ytterrørets 11 innerdiameter. Ved den ene ende av innerrøret er skrueplatenes 18,19 ender festet på to omtrent diametralt motsatt liggende steder til endeflensen 16, mens skrueplatenes motsatte ender er avsluttet i avstand fra flensringen 17, slik at passasjene 20,21 møter hverandre i mellomrommets endeparti 22. Mellomrommet selv er betegnet med 23. Når varmeveksleren er i montert tilstand, er rørenes flensringer 13 og 17 skrudd sammen ved hjelp av bolter 24 og muttere 25 og lukker tett mellomrommets 23 endeparti 22. Coaxially with the outer tube 11, there is an inner tube 15 of almost equal length with a substantially smaller diameter than that of the outer tube. At one end, the inner pipe 15 carries a blind flange 16 with the same outer diameter as the flange ring 5 of the housing 1. At its other end, the inner pipe 15 carries an outer flange ring 17 with a slightly smaller outer diameter than the outer pipe 11's inner diameter. This end of the pipe is open and flush with the flange opening 14 in the outer pipe. The length of the pipes 11, 15 is adapted so that the flange rings 13, 17 lie against each other when the flanges 12, 16 of the pipes are in contact with each other. On the inner tube 15 are attached two screw-shaped plate walls or wings 18 respectively. 19 which between them form two continuous, helical passages 20 respectively. 21. The plate walls 18,19 are firmly connected to the inner tube 15 and have an outer diameter that matches the inner diameter of the outer tube 11. At one end of the inner tube, the ends of the screw plates 18,19 are fixed in two approximately diametrically opposite locations to the end flange 16, while the opposite ends of the screw plates are terminated at a distance from the flange ring 17, so that the passages 20,21 meet each other in the end part 22 of the intermediate space. is itself denoted by 23. When the heat exchanger is in the assembled state, the flange rings 13 and 17 of the pipes are screwed together by means of bolts 24 and nuts 25 and tightly closes the end part 22 of the space 23.
Innerrørets 15 endeflens 16 er utstyrt med en sentral inn-løpsstuss 27 - i dette tilfelle for innføring av opp-hetningsdamp. Videre er endeflensen 16 forsynt med to diametralt motsatt beliggende stusser, nemlig innløpsstuss 28 for vann som skal oppvarmes og utløpsstuss 29 for det oppvarmede vann. Inn- >' løpsstussen 28 er i direkte forbindelse med passasjen 20, og ut-løpsstussen 29 i direkte forbindelse med passasjen 21. Ved den nå omtalte ende av varmeveksleren er flensene 5,12 og 16 forsynt med hull som er i flukt med hverandre for sammenskruing ved hjelp av bolter 30 med muttere 31. Det ytre mellomrom er merket 32. The end flange 16 of the inner pipe 15 is equipped with a central inlet nozzle 27 - in this case for the introduction of heating steam. Furthermore, the end flange 16 is provided with two diametrically opposite nozzles, namely inlet nozzle 28 for water to be heated and outlet nozzle 29 for the heated water. The inlet nozzle 28 is in direct connection with the passage 20, and the outlet nozzle 29 in direct connection with the passage 21. At the now mentioned end of the heat exchanger, the flanges 5, 12 and 16 are provided with holes which are flush with each other for screwing together using bolts 30 with nuts 31. The outer space is marked 32.
Når varmeveksleren er i drift, føres medium som skal oppvarmes, i dette tilfelle vann, gjennom stussen 28 og vil strømme langs den ene skrueformede passasje 20 mot mellomrommets 2 3 endeparti 22, hvor det vil utsettes for en retningsforandring på 180° og vil fortsette å strømme tilbake gjennom passasjen 21 for i opphetet tilstand å forlate varmeveksleren gjennom utløpsstus-sen 29. Overhetet damp føres inn gjennom den sentrale stuss 27 og vil passere innerrøret 15 og deretter mellomrommet mellom yt-terrøret og huset ved bunnen 3 og langs veggen 2 for å forlate huset som nedkjølt damp eller kondensat gjennom utløpsstussen 8. Varme fra dampen overføres til vannet både gjennom innerrøret 15 og ytterrøret 11. En viss varmeoverføring finner også sted gjennom skilleveggene 18,19. Forskjellige strømmende/flytende medier kan oppvarmes hhv. kjøles. Som eksempel kan nevnes olje, salt-lake, maling, luft og diverse gasser osv. When the heat exchanger is in operation, the medium to be heated, in this case water, is passed through the spigot 28 and will flow along the one helical passage 20 towards the end part 22 of the space 2 3, where it will undergo a change of direction of 180° and will continue to flow back through the passage 21 to leave the heat exchanger in a heated state through the outlet nozzle 29. Superheated steam is introduced through the central nozzle 27 and will pass the inner tube 15 and then the space between the outer tube and the housing at the bottom 3 and along the wall 2 to leave the house as cooled steam or condensate through the outlet nozzle 8. Heat from the steam is transferred to the water both through the inner pipe 15 and the outer pipe 11. Some heat transfer also takes place through the partitions 18,19. Different flowing/liquid media can be heated or cooled. Examples include oil, brine, paint, air and various gases, etc.
Når varmeveksleren skal tas fra hverandre, løsnes først boltene 30 og rørinnsatsen 10 trekkes ut. Deretter løsnes bolt-forbindelsen 24,25 og innerrøret trekkes ut av ytterrøret. When the heat exchanger is to be taken apart, the bolts 30 are first loosened and the tube insert 10 is pulled out. The bolt connection 24,25 is then loosened and the inner tube is pulled out of the outer tube.
Varmevekslerens kapasitet kan tilpasses de forskjellige formål ved endring av varmevekslerens totale lengde, endring av skruestigningen for skilleveggene og endring av skilleveggenes radiale høyde. Konstruksjonen er fortrinnsvis utført som en sveiset konstruksjon av stål, men andre materialer og forbindel-sesmåter kan benyttes. The heat exchanger's capacity can be adapted to the different purposes by changing the heat exchanger's total length, changing the screw pitch for the partitions and changing the radial height of the partitions. The construction is preferably made as a welded construction of steel, but other materials and connection methods can be used.
Modifikasjoner kan forekomme. Husets bunn 3 kan f.eks. erstattes med lokk. "Skruen" kan da vendes 180° i mellomrommet 23 og stussene 28,29 føres gjennom lokket. Den viste konstruksjon er imidlertid -den enkleste. Ved vertikal utførelse"*vil av-løpet 8 være i bunnen 3. Modifications may occur. The bottom of the house 3 can e.g. replaced with a lid. The "screw" can then be turned 180° in the space 23 and the spigots 28,29 passed through the lid. The construction shown is, however, the simplest. In the case of a vertical design"*, the outlet 8 will be at the bottom 3.
