Description
Anordning ved varmeveksler. Device at heat exchanger.
Oppfinnelsen vedrbrer varmeveksler av det slag hvor to medier The invention relates to heat exchangers of the kind where two media
i gass eller væskeformig tilstand er gjenstand for en varmeveksling gjennom termoledende vegger i en varmeveksler utformet som dobbeltrbr med et antall mediefbrende kanaler. in a gas or liquid state is the subject of a heat exchange through thermoconductive walls in a heat exchanger designed as a double tube with a number of medium-conducting channels.
For varmevekslere som oljevarmere eller oljekjblere av "Shell and Tube" - typen kan det varmende mediet være vann eller damp, eller kjolende medium vann eller Tcjblevæske som fordamper innvendig i rorene og at oljen som varmes opp eller kjoles går utvendig på rorene. For heat exchangers such as oil heaters or oil coolers of the "Shell and Tube" type, the heating medium can be water or steam, or cooling medium water or Tcjble liquid that evaporates inside the pipes and that the oil that is heated or cooled goes outside the pipes.
Ved store temperaturdifferanser blir det ulik ekspansjon mellom rorene som er innfestet i endebunnene og det utvendige ror, og det er vanlig å lage varmevekslere slik at hele rbrsatsen innvendig kan ekspandere ved at den ene ende av rbrsatsen glir på en eller to pakninger. Hele rbrsatsen kan i alminnelighet også trekkes ut av det utvendige ror. In the event of large temperature differences, there will be different expansion between the pipes that are attached to the end bases and the external pipe, and it is common to make heat exchangers so that the entire pipe set can expand internally by one end of the pipe set sliding on one or two gaskets. The entire rudder set can generally also be pulled out from the outer rudder.
Slike varmevekslere kan som nevnt være av den såkalte "Shell Such heat exchangers can, as mentioned, be of the so-called "Shell
& Tube"-typen, hvor det ene mediet går i ror festet i ende-bunner i et stål-, metallrbr eller annet materiale. Rorene kan være festet i endebunnene ved innvalsing, sveising, lodding eller annen festemetode. Utvendig på rorene går det andre mediet i motstrbm eller tverrstrbm ved hjelp av ledeplater. Varmeveksleren kan også være av dobbeltrbrtype, hvor det ene mediet går innvendig i et senterrbr og det andre mediet i mellomrommet mellom dette senterrbr og det utvendige roret. & Tube" type, where one medium goes in pipes fixed in end-bottoms in a steel, metal tube or other material. The pipes can be fixed in the end-bottoms by rolling, welding, soldering or another fastening method. On the outside of the pipes, the other goes the medium in counterflow or transverse flow using guide plates. The heat exchanger can also be of the double tube type, where one medium goes inside a central tube and the other medium in the space between this central tube and the outer tube.
Den foreliggende oppfinnelse vedrbrer en varmeveksler som loser problemet når det gjelder ekspansjon og som kjennetegnes ved at de mediefbrende kanaler som er utformet som dobbeltrbr for det ene medium har tillbp og avlbp for mediet på en og samme side, at tillbpet skjer gjennom et senterrbr til et stykke fra bunnen i et utvendig ror og at mediet på kjent måte returnerer fra et vendekammer og gjennom mellomrommet mellom senterrbret og det utvendige ror samt at det ytre rors tilpluggede ende er glidbart festet, f. eks. i en styreplate for å tillate fri ekspansjon. The present invention relates to a heat exchanger which solves the problem in terms of expansion and which is characterized by the fact that the medium-carrying channels, which are designed as double tubes for one medium, have inlet and outlet for the medium on one and the same side, that the inlet takes place through a central tube to a piece from the bottom in an outer rudder and that the medium returns in a known manner from a turning chamber and through the space between the center rib and the outer rudder and that the plugged end of the outer rudder is slidably fixed, e.g. in a guide plate to allow free expansion.
Fig. 1 viser et snitt av en varmeveksler ifblge oppfinnelsen. Fig. 1 shows a section of a heat exchanger according to the invention.
De enkelte ror i rbrsatsen er festet i en endebunn på vanlig måte ved valsing, sveising, lodding eller annen festemetode. The individual rudders in the rbr set are attached to an end base in the usual way by rolling, welding, soldering or another attachment method.
I andre enden blir rorene tettet med en lbsbar eller innloddet plugg. Det kjblende eller varmende medium fores inn gjennom et senterrbr i de enkelte ror i rbrsatsen til et stykke fra rorets pluggede ende, hvor mediet slippes ut for å returnere fra vende-kammeret j og gjennom mellomrommet c mellom senterrbret og det utvendige ror b. Mediets tillbp og avlbp skjer fra to adskilte rom, hvor senterrbrene a er festet i veggen f mellom rom d og e og hovedrbrene i veggen g. Tillbp og avlbp skjer således på samme side, og rbrsatsen kan bevege seg fritt. At the other end, the rudders are sealed with a lbsbar or soldered plug. The cooling or heating medium is fed through a center tube into the individual tubes in the tube set to a distance from the plugged end of the tube, where the medium is released to return from the turning chamber j and through the space c between the center tube and the outer tube b. Addition of the medium and avlbp takes place from two separate rooms, where the center beams a are fixed in the wall f between rooms d and e and the main beams in the wall g. Tillbp and ablbp thus take place on the same side, and the rib set can move freely.
I mellomrommet mellom senterrbr og utvendig ror kan det even-tuelt legges en skruevikling med en bestemt stigning for å oke effekten ved at hastigheten kan tilpasses det som gir det beste varmeovergangstallet for det gjeldende mediet. Et utvendig mantelrbr h er festet til veggen g for hovedrbrene, og kan tas av, slik at rbrsatsen kan rengjbres og besiktiges. In the space between the center rib and the outer rudder, a screw winding with a specific pitch can possibly be placed to increase the effect by allowing the speed to be adapted to that which gives the best heat transfer figure for the current medium. An external casing pipe h is attached to the wall g for the main pipes, and can be removed, so that the pipe set can be cleaned and inspected.
