Abstract
Description
Die Erfindung betrifft eine Destillationsanlage, wie sie im besonderen zur Meerwas serentsalzung eingesetzt wird. Das Ziel der Erfindung besteht in einer wirksamen thermischen Destillationsanlage, die gegenüber dem bekannten MSF-Verfahren bei gegebenem Energieeinsatz - und Investitionsvolumen eine höhere Produktausbeute erreicht.The invention relates to a distillation plant, in particular for sea water desalination is used. The aim of the invention is an effective one thermal distillation plant, which compared to the known MSF process given energy and investment volume a higher product yield reached.
Zur Erreichung dieses Ziels weist die Anlage folgende Merkmale auf: Analog zu be stehenden Single Stage Flash (SSF) - und Multi Stage Flash (MSF) Anlagen enthält die Anlage eine (SSF) oder mehrere (MSF = mit Temperatur- und Druckgefälle) Kam mern, in denen bei Unterdruck Meerwasser verdampft und bei räumlicher Absonde rung kondensiert wird.To achieve this goal, the system has the following features: Analogous to be Standing Single Stage Flash (SSF) and Multi Stage Flash (MSF) systems contain the Plant one (SSF) or several (MSF = with temperature and pressure gradient) Kam in which sea water evaporates under negative pressure and in the case of spatial probe tion is condensed.
Abweichend zum bekannten MSF-Verfahren wird im Kondensationsteil dieser Kammern Kondensationswärme nicht direkt an die als Wärmetauscher wirkenden Meerwassereinlaufrohre abgegeben, sondern der Meerwassereinlauf bleibt von der Kondensationsseite der Verdampfungskammern räumlich getrennt. Es wird ein Wärmetauschelement mit doppeltem Phasenwechsel flüssig/gasförmig im Kondensa tionsteil der Kammern und gasförmig/flüssig im Meerwassereinlauf eingeschaltet. Dieses Wärmetauschelement wird im Naturumlauf betrieben, es enthält ein Fluid (in der Regel Wasser) und wird auf die jeweilige Kammer mit der aufzunehmenden Ent halphie und der gegebenen Druck- und Temperaturverhältnisse abgestimmt. Die Gleichzeitigkeit der Abgabe von Kondensationswarme im Kondensationsteil mit der Aufnahme von Verdampfungswärme durch Phasenwechsel im Wärmetauscher er möglicht eine bessere Wärmeübertragung, so daß eine Verringerung der korrosions gefährdeten und damit hochwertige Wertstoffe bedingende Kondensatorflächen und eine größere Temperatur- und Druckabsenkung und damit eine höhere Produktaus beute pro Kammer möglich ist.In contrast to the known MSF process, this is in the condensation part Chambers do not condense heat directly to those acting as heat exchangers Seawater inlet pipes given off, but the seawater inlet remains from the Condensation side of the evaporation chambers spatially separated. It will be a Heat exchange element with double phase change liquid / gaseous in the condenser tion part of the chambers and gaseous / liquid in the seawater inlet switched on. This heat exchange element is operated in natural circulation, it contains a fluid (in usually water) and is applied to the respective chamber with the Ent halphie and the given pressure and temperature conditions. The Simultaneous delivery of heat of condensation in the condensation part with the Absorption of heat of vaporization by phase change in the heat exchanger possible better heat transfer, so that a reduction in corrosion endangered and thus high quality recyclable condenser surfaces and a greater reduction in temperature and pressure and thus a higher product loot per chamber is possible.
Es ergibt sich folgendes Schema: Von der Endvorwärmung kommendes Meerwasser 1 tritt in die Verdampfungskammer 2 ein, wird dort verdampft, über einen Demi ster (Tropfenabscheider) 3 in die Kondensationskammer geleitet 4 und dort kon densiert 5. Die Kondensationswärme des kondensierenden Dampfes wird über einen Wärmetauscher mit doppeltem Phasenwechsel 5a und 5b in den Meerwas sereinlauf 6 abgeführt, das der Endvorwärmung zugeführt wird. Die eingedickte Sole 7 wird abgeführt und ggf. einer weiteren Kammer zugeführt. Das entsalzte Wasser 8 wird abgeleitet.The following scheme results: Sea water 1 coming from the final preheating enters the evaporation chamber 2 , is evaporated there, passed via a demister (droplet separator) 3 into the condensation chamber 4 and condensed there 5 . The heat of condensation of the condensing steam is removed via a heat exchanger with a double phase change 5 a and 5 b in the seawater inlet 6 , which is fed to the final preheating. The thickened brine 7 is removed and, if necessary, fed to a further chamber. The desalinated water 8 is drained off.
