Description

Uppfinnare: S K Jenssen Foreliggande uppfinning hänför sig till plattvarmevaxlare med till i horisontell led losbart paket sammanhallna i huvudsak vertikalt stallda varmeoverforingsplattor och speciellt till dylika varmevaxlare dar tva sadana paket i en apparatenhet (dubbelapparat) bilda var sin av tvâ fran varandra skilda varmeutvaxlingssektioner, anordnade att arbeta oberoende av varandra. Huvudandamalet med en sadan dubbelapparat är att skapa mojlighet att driva tva fran varandra skilda varmeutvaxlingsprocesser med mindre apparatkostnad och platsbehov for apparatur an vid anvandning av separata enheter (enkelapparater) ; en for vardera processen. Genoni hittills framstallda dubbelapparater har man emellertid endast i begransad utstrackning kunnat tillgodose detta huvudandamal och delta dartill pa bekostnad av majligheten att avstalla de bhda sektionerna oberoende av varandra far t. ex. inspektion, rengaring och utbyte av varmeoverforingsplattor, varom skall redogoras mer i detalj nedan, och vilket fir en avsevard olagenhet. Inventor: SK Jenssen The present invention relates to plate heat exchangers with heat transfer plates held together in horizontally detachable packages and especially to such heat exchangers where two such packages in an apparatus unit (double apparatus) each form a heat exchange separated by two different axes. work independently. The main purpose of such a dual device is to create the possibility of operating two separate heat exchange processes with less device cost and space requirements for equipment than when using separate units (single devices); one for each process. However, duplicate devices produced so far have only been able to meet this main objective to a limited extent and participate in it at the expense of the possibility of storing the two sections independently of each other, e.g. inspection, cleaning and replacement of heat transfer plates, which will be explained in more detail below, and which leads to a significant malfunction.

Uppfinningen avser bade att forbattra effekten med avseende pa huvudandamalet och att undanroja namnda olagenhet. Den baserar sig pa den kanda anordningen att vardera varmeutvaxlingssektionen bestar air ett plattpaket som fir sammanhallet mellan i paketets ena ande en gavel, som ar forsedd med varmeutvaxlingssektionens in- och avlopp for varmeutvaxlande media, och i paketets andra ande en tackplatta och kannetecknas darav, att tva dylika gavlar, en for vardera plattpaketet, aro anordnade att utgtira stod for ett barorgan, pa vilket, mellan dessa gavlar, de tva plattpaketen samt Ira desamma atskiljande tackplattor, en for vardera plattpaket, aro anordnade, att mellan vardera gaveln och narliggande tackplatta fines ett 16shart forband for sammanhallning av det mellanliggande plattpaketet samt att avstandet mel lan de hada sammanhallna plattpaketens respektive tackplattor är stort nog att tilltta vilket som heist av plattpaketen att Indian sin gavel och det andra sammanhallna plattpaketet upplasas far inspektion, rengoring och uttagning av de enskilda varm:eiiverforingsplattorna. The invention intends both to improve the effect with respect to the main object and to eliminate said illegality. It is based on the known device that each heat exchange section consists of a plate package which carries the joint between in one end of the package a gable, which is provided with the heat exchange section inlet and drain for heat exchanging media, and in the other end of the package a roof plate and can be marked therefrom. two such ends, one for each plate package, are arranged to extend to a bar member, on which, between these ends, the two plate packages and the same separating roof plates, one for each plate package, are arranged so that between each end plate and adjacent roof plate there is a 16shart connection for cohesion of the intermediate tile package and that the distance between the hada cohesive tile packages and roof tiles is large enough to increase whichever of the tile packages that Indian's gable and the other cohesive tile package are loaded for inspection, cleaning and removal of the individual heat : eiiverforingsplattorna.

Uppfinningen skall nedan narmare beskrivas med hanvisning till bifogade ritning dar fig. 1 illustrerar fran sidan en enkelapparat med varmeutvaxlingsektion air det slag pa vilket uppfinningen baserar sig, fig. 2 illustrerar samma enkelapparart Iran vanster i fig. 1, fig. 3 illustrerar fran sidan en kand utfiiringsform av dubbelapparat med tva varmeutvaxlingssektioner enligt fig. 1 och fig. 4 illustrerar fran sidan en dubbelapparat enligt uppfinningen likash med tvâ varmeutvaxlingssektioner enligt fig. 1. The invention will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 illustrates from the side a single apparatus with a heat exchange section in the manner on which the invention is based, Fig. 2 illustrates the same single apparatus Iran in Fig. 1, Fig. 3 illustrates from the side a The known embodiment of a dual apparatus with two heat exchange sections according to Fig. 1 and Fig. 4 illustrates from the side a dual apparatus according to the invention similar to two heat exchange sections according to Fig. 1.

Figurerna aro schematiska och endast avsedda att tjana som exempel. Identiska detaljer aro i de olika figurerna forsedda med samma hanvisningsbeteckningar. The figures are schematic and only intended to serve as examples. Identical details are in the different figures provided with the same male designation designations.

Darmed kan en fackman av fig. 1 och 2 latt igenkanna en enkelapparat dar plattpaketet 1 och detsammas tackplatta 2 aro glidbart i horisontell led upphangda pa en barstang 3 mellan en gavel 4 och en pelare 5 som tillsammans utgora stod for barstangen 3, varvid plattpaketet sammanhalles mellan gaveln och tackplattan medelst losbara bultforband 6 och gaveln fir forsedd med fyra studsar 7, 8, 9 och 10 som tjanstgora som in- respektive avlopp for tvâ varmeutvaxlande media sâ att det ena mediet kan ledas t. ex. in genom stud- Dupl. kl. 53 e: 2 2— — sen 7 passera genom vartannat plattmellanrum och ut genom studsen 8 medan det andra mediet passerar genom de ovriga plattmellanrummen t. ex. i motstrom in genom studsen 9 och ut genom studsen 10. Avstandet s mellan tackplattan 2 och pelaren 5 kan aven av fackmannen forstas vara avpassat att da forbanden & losas tillata tackplattan och de enskilda plattorna i paketet att skjutas isar pd barstangen i tillracklig grad for inspeklion, rengoring och eventuell uttagning av enskilda plattor. For uppfinningens beskrivning onOdiga men for dylika apparater brukliga ytterligare detaljer sasom ytterligare styrningar for plattorna, storre antal bultforband o. d. aro utelamnade av tydlighetsskal, vilket aven galler ovriga figurer. Gaveln 4, plattpaketet 1 och tackplattan 2 utgora tillsammans en enda varmeutvaxlingssektion. The plate packages have in the various figures only been indicated by tata vertical lines, but are assumed to consist of ph edge salt to packages with as passage channels for heat-exchanging media serving elastic edge packs dulled spaces between interconnected heat transfer plates. Thus, a person skilled in the art of Figs. 1 and 2 can easily recognize a single apparatus in which the plate package 1 and its roofing plate 2 are slidably suspended in horizontal direction on a bar rod 3 between a gable 4 and a pillar 5 which together formed the bar rod 3, the plate package being held together between the end wall and the roof plate by means of detachable bolt joints 6 and the end wall provided with four bounces 7, 8, 9 and 10 which serve as inlet and outlet for two heat-exchanging media, respectively, so that one medium can be led e.g. in through stud- Dupl. at 53 e: 2 2— - then 7 pass through every other plate gap and out through the bounce 8 while the other medium passes through the other plate gaps e.g. in countercurrent in through the bounce 9 and out through the bounce 10. The distance s between the roof plate 2 and the pillar 5 can also be understood by those skilled in the art to be adapted so that when the joints & loosened allow the roof plate and the individual plates in the package to slide on the bar bar sufficiently for inspection. , cleaning and possible removal of individual tiles. For the description of the invention unnecessary but usual for such devices additional details such as additional guides for the plates, larger number of bolted joints, etc. are omitted from clarity shells, which also applies to other figures. The end plate 4, the plate package 1 and the roof plate 2 together form a single heat exchange section.

Fran denna enkelapparat har det kanda slaget av dubbelapparat enligt fig. 3, utvecklats pa foljande satt: Pa den forlangda barstangen 3a har pa den i fig. 1 fria sidan orn tackplattan 2 upphangts ett ytterligare platt-paket 1 med gavel 4a av i princip samma slag som gaveln 4, varvid bada plattpaketen och 'den for dessa gemensamma tackplattan 2 sammanhallas av ett forlangt bultforband 6a mellan gaveln 4 och gaveln la som är forsedd 'Tried in- och avloppsstudsar 7a, 8a, 9a, och "10a for detta ytterligare plattpaket motsvarande studsarna 7, 8, 9, och la for det forsta plattpaketet. Avstandet 2s mellan gaveln 4a och pelaren , erfordras for att tillata hada plattpaketen tillsammans att saras pa barstangen 3a for inspektion, rengoring och even- luelitav enskilda plattor. From this single device the known type of double device according to Fig. 3 has been developed in the following way: On the required bar rod 3a, on the free side in Fig. 1 the roof plate 2 has been hung a further plate package 1 with end 4a of basically the same such as the gable 4, both the plate packages and the roof plate 2 common to them being held together by a required bolt connection 6a between the gable 4 and the gable 1a provided with threaded inlet and drain spouts 7a, 8a, 9a, and 10a for this further plate package. corresponding to the bounces 7, 8, 9, and 1a for the first plate package.The distance 2s between the gable 4a and the pillar, is required to allow the plate packages together to be wound on the bar rod 3a for inspection, cleaning and possibly of individual plates.

En jamforelse mellan denna dubbelapparat .och tva enkelapparater uppstallda i rad efter varandra med pelarna 5 vanda mot varandra (tvaapparatsystem) gem foljande resultat: Vinsten i platsbehov kan ej bli sarskilt stor da langden av dubbelapparaten blir ungefar densamma som den sammanlagda langden air de tva enkelapparaterna. Vinsten genom reduktion av erforderliga konstruktionselement blir i huvudsak den all en pelare 5 samt en tackplatta 2 bortfaller. En konstruktiv olägenhiet bestar dari att olika gavlar (med och utan fotplatta) maste tillverkas och lagerhallas. Den va.sentligaste olagenheten ligger emellertid dari att man icke kan: upplosa de bada plattpaketen var for sig utan maste alta bada varmeutvaxlingssektionerna ur drift sa snart nagot av plattpaketen behtiver giros alkomligt fOr t. ex. inspektion, ring och utbyte av plattor. Darvid maste dessutom gavelns 4a forbindelser med yttre rOrledningar losas och dessa ledningar vara anslutna till gaveht fran densammas sida sa att de ej hindra gavelns rorelse pO. barstangen. Gaveln. 4a kan darfor ej vara forsedd med raka studsar for in- och avloppen som gaveln 4 utan maste forses med i rat vinkel krOkta studsar ena sidans studsar 7a och 8a at ena sidan och andra sidans at ritningen bakomliggande studsarna 9a och 10a at andra sidan. A.ven i detta avseende am alltsa gaveln 4a olik gaveln 1. A comparison between this dual device and two single devices arranged in a row with the columns 5 facing each other (two-device system) with the following results: . The gain by reducing the required structural elements is essentially that all a pillar 5 and a roof plate 2 are omitted. A constructive inconvenience consists in the fact that different ends (with and without foot plate) must be manufactured and stored. The most important disadvantage, however, is that it is not possible to: dissolve the two plate packages separately, but all the heat exchange sections must be taken out of operation as soon as some of the plate packages need to be switched on, e.g. inspection, ringing and replacement of plates. In addition, the connections of the gable 4a with external pipelines must be loosened and these lines must be connected to the gate from the same side so that they do not impede the movement of the gable. bar rod. The gable. 4a can therefore not be provided with straight bounces for the inlets and drains such as the end wall 4, but must be provided with at right angles. A.alv in this respect, therefore, the end 4a differs from the end 1.

Den dubbelapparat enligt uppfinningen, som illustreras i fig. 1 bestar av en barstang 3b pa -silken tva plattpaket 1 med desamma atskiljande tvO tackplattor 2, en for vardera plattpaketet, aro upphangda mellan tva gay-tar 4, en for vardera plattpaketet, vilka gavlar utgara stod fiir barstangen. Vardera plattpaketet am sammanhallet mellan sin gavel och sin tackplatta medelst bultforband 6, varvid fOrefinnes ett avstand mellan tackplattorna som Or minst s dvs. sit stort att vilket som heist av plattpaketen under utnyttjande av detta utrymme kan saras pa barstangen i tillra.cklig grad for inspektion, rengoring och uttagning av de enskilda plattorna. The double apparatus according to the invention, illustrated in Fig. 1, consists of a bar rod 3b on the silk two plate packages 1 with the same separating two roof plates 2, one for each plate package, suspended between two gay bars 4, one for each plate package, which ends utgara stood for the bar. Each plate package is the joint between its end wall and its roof plate by means of bolted joints 6, whereby there is a distance between the roof plates which is at least s, i.e. It is important that any lift of the plate packages during the use of this space can be wound on the bar to a sufficient degree for inspection, cleaning and removal of the individual plates.

Om man i stallet jainfOr denna dubbelapparat enligt uppfinningen med samma tvaapparatsystem som i foregaende jamforelse firmer man att den lona kan tankas vara framstalld ur det senare genom att tvaapparatsystemets hada barstanger 3 ersatts med en sammanhangande barstang 3b, varvid hada pelarna 5 borttagits, vilket representerar en vinst genom reduktion air erforderliga konstruktionselement som kan anses vara ungefar likvardig med samma vinst genom borttagning av en pelare och en tackplatta i den foregaende jamforelsen. Daremot behava utom den langre barstangen inga for dubbelapparaten speciella element tillverkas och lagerhallas emedan den i ovrigt bestar av med., enkelapparatens element identiska element. If instead of this double apparatus according to the invention with the same two-apparatus system as in the previous comparison, it is found that the lona can be thought to have been produced from the latter by replacing the two apparatus system bar bars 3b with a continuous bar bar 3b, whereby the pillars 5 have been removed. gain by reduction air required structural elements that can be considered to be approximately equivalent to the same gain by removing a pillar and a roof tile in the previous comparison. On the other hand, apart from the longer bar, no special elements for the dual device are manufactured and stored because it otherwise consists of identical elements of the single device.

Den vasentligaste fordelen ligger emellertid dari att man kan upplosa var varmeutvaxlingssektion for sig utan att samtidigt behOva satta den andra ur drift och utan att behova losa nagra av varmevaxlarens forbindelser med yttre rorledningar for varmeutvaxlande media. Om man begransar avstandet mellan thekplattorna sa att det atminstone inte airsevitrt overstiger minimimattet s far man dam-till en tydlig minskning air utrymmesbehovet. The most important advantage, however, is that one can dissolve each heat exchange section separately without having to put the other out of operation at the same time and without having to loosen any of the heat exchanger's connections to external pipes for heat exchanging media. If you limit the distance between the teak plates so that it at least does not airsevitrt exceed the minimum mat then you get dam- to a clear reduction in air space requirements.

En begransning an avstandet 2s i fig. 3 i sadan grad kan ej genomfOras Even om man skulle avse att enbart sara ett paket i taget for inspektion och rengoring av plattorna. St snart forbanden 6a loses kommer namligen hada plattpaketen att, genom det upphorande trycket mot de mellanliggande randpackningarna, fjadra isar till en 30 a 40 % Rad langd med mellanrummen mellan plattorna fortfarande slutna utat, vilket betyder lika stor for-lust av del for sarningen av plattorna effektiva avst'ndet. Vid apparaten enligt uppfinningen begransar sig denna fOrlust till endast det ena paketets isarfjadring. A limitation of the distance 2s in Fig. 3 to such an extent cannot be carried out even if one were to mean only one package at a time for inspection and cleaning of the plates. Namely, as soon as the joints 6a are loosened, the plate packages will, due to the ceasing pressure against the intermediate edge packings, spring ice to a 30 to 40% line length with the spaces between the plates still closed outwards, which means an equal loss of part for the separation of the plates effective distance. In the apparatus according to the invention, this loss is limited to the ice suspension of only one package.
