Dampfverflüssigungsgefäß. Patentiert im Deutschen Reiche vom 21. November 1913 ab. Vapor condensing vessel. Patented in the German Empire on November 21, 1913.
Bei den bekannt gewordenen Oberflächenkondensatoren ist der Wärmeaustausch um so größer, je rascher das Kühlwasser die Röhren durchströmt, und er wird noch gesteigert, wenn das Durchlaufen des Kühlwassers in Wirbelungen erfolgt. Das Kühlwasser läuft zur Beschleunigung in dem Röhrenbündel hin und her, wobei der im Gefäß zu verflüssigende Dampf die Röhrenbündel vorteilhaftThe heat exchange is the same with the surface capacitors that have become known bigger, the faster the cooling water flows through the tubes, and it is still increased, when the cooling water passes through in eddies. The cooling water is running for acceleration back and forth in the tube bundle, the one to be liquefied in the vessel Steam the tube bundle advantageously
ίο im Gegenstrom zum Kühlwasserlauf umspült
in einem dem letzteren entsprechenden, mittels Leitbleche vorgeschriebenen, mitunter zweigeteilten
Strome.
Besondere Dampfbeschleunigungsmittel haben in derartig betriebenen Kondensatoren den
Wärmeaustausch merklich zu erhöhen nicht vermocht, weil bei einem zusammengeballten,
rasch laufenden Dampfstrom nur die die Röhren bestreichenden Moleküle ihre Wärme verlierenίο in countercurrent to the cooling water flow flows around in a flow corresponding to the latter, prescribed by means of guide plates, sometimes divided into two.
Special steam accelerators have not been able to noticeably increase the heat exchange in condensers operated in this way, because only the molecules brushing the tubes lose their heat in a concentrated, rapidly flowing steam stream
ao und die im Strominnern schwingenden Moleküle in Entwärmungsverzug kommen, das verflüssigte Wasser aber in schnellen Dampfströmen erst recht die Röhren entlang mitläuft, auch auf den Leitblechen wieder nach verdampft.ao and the molecules oscillating inside the stream are delayed in cooling, the liquefied But water also runs along the tubes in rapid steam streams, too evaporated again after the baffles.
Diese Hemmungen des Wärmeaustausches lassen sich nur beheben, wenn der Dampfstrom aufgelöst wird in viele, .spiralartige Strömungen mit erzwungenen, heftigen Wirbelungen, die auch das verflüssigte Wasser rasch abschleudern. Das kann nicht zweifelhaft sein; denn, da es feststeht, daß der Wärmeaustausch bei mittels Wirbelstreifen in den Röhren diese wirbelnd durchlaufenem Kühlwasser sich ungemein erhöht gegenüber auf gewöhnliche Art durchfließendem Wasser, so müssen auch vielfache Dampfströme mit erzwungenen, heftigen Wirbelungen an und um die Röhren eine molekulare Erneuerung ihrer Entwärmung erbringen.These inhibitions of heat exchange can only be removed if the steam flow it is resolved into many, spiral-like currents with forced, violent eddies, which also quickly throw off the liquefied water. That cannot be doubtful; because, since it is certain that the heat exchange by means of vortex strips in the tubes these whirling through cooling water increases immensely compared to the usual way water flowing through, so must also multiple streams of steam with forced, violent Eddies on and around the tubes bring about a molecular renewal of their cooling.
Diese Vorgänge begründen die neue Wirkung des Erfindungsgegenstandes, der in dem gezeichneten, stehenden oder liegenden Rundgefäß die neuen Vorrichtungen im Schnitt, parallel dem Röhrenbündel, veranschaulicht.These processes justify the new effect of the subject matter of the invention, which in the drawn, standing or lying round vessel illustrates the new devices in a section, parallel to the tube bundle.
Der zu verflüssigende Dampf tritt bei α ein und speist eine beliebige Anzahl in der Mitte des Röhrenbündels eingebauter Dampfrohre b verschiedener Weiten und Längen, die zwischen einander konzentrische Ringrohrwege freilassen und in runden Dampfscheiben e endigen. Die Dampfscheiben erhalten am Rande ringsum Düsenschlitze zwischen den Dampfstrom ablenkenden, tangential sitzenden Stegwänden d, derart, daß die einzelnen Schlitze nicht in der Kreismittelebene, sondern schrägwinklig davon im Scheibenrand ausmünden. Die aus den Düsen strömenden Dampfstrahlen müssen infolgedessen sich heftig und spiralig an und um die Röhren wirbeln und auch das verflüssigte Wasser rasch abschleudern, das bei c, bei liegenden Gefäßen bei f, zur Naßluftpumpe mit der Luft zusammen abfließen kann.The vapor to be liquefied enters at α and feeds any number of vapor tubes b of various widths and lengths installed in the center of the tube bundle, which leave concentric ring pipe paths between each other and end in round steam disks e. The steam disks are provided with nozzle slots all around the edge between the tangentially seated web walls d which deflect the steam flow, in such a way that the individual slots do not open out in the central plane of the circle, but at an angle from it in the edge of the disk. As a result, the steam jets flowing out of the nozzles have to swirl violently and spirally on and around the tubes and also quickly throw off the liquefied water, which can flow off with the air at c, with horizontal vessels at f, to the wet air pump.
Diese organisch gestaffelte, zentrale Dampfverwirbelung gestattet die Verwendung besonders langer Röhrengefäße, weil das Kühlwasser dann in den Röhren auch ohne die bei kürzeren Gefäßen nötige abteilige Hin- und Herführung einen hinreichend langen Weg zurücklegt.This organically staggered, central steam turbulence allows the use in particular long tubular vessels, because the cooling water then enters the tubes without the separate back and forth that is necessary with shorter vessels Bringing back a sufficiently long way.
