Abstract

The device has an evaporation space equipped with a distribution device for a fluid, where energy of condensable gases is used directly for processing of fluids by evaporation. The evaporation space is equipped with a cleaning device. The device operates under certain atmospheric pressure, where the gas is condensed to water from moist air.

Description

Im Zuge der Kostenentwicklung bei den Energiekosten, die sich auf allen Gebieten der Wertschöpfung auswirkt, ist die Entwicklung neuer Techniken zur Nutzung so genannter minderwertiger Energie notwendig.in the The cost of energy costs, which affect everyone Areas of added value is the development of new techniques for the use of so-called inferior energy necessary.

Ziel der erfindungsgemäßen Vorrichtung ist es, Energie auf niedrigem Temperaturniveau oder geringer Dichte zur Aufarbeitung bzw. Aufkonzentrierung von flüssigen Abfällen und Prozessflüssigkeiten usw. zu nutzen. Der Transport und die Aufarbeitung ist im allgemeinen mit einem erheblichen Aufwand von Energie fossiler Herkunft verbunden, während auf der anderen Seite bisher nicht nutzbare Energie an die Umgebung abgegeben wird. Da die Prozesse der Kondensation und der Verdunstung bei Atmosphärendruck ablaufen, können die erfindungsgemäßen Vorrichtungen ohne besondere statische Anforderungen gebaut werden.aim the device according to the invention it is energy at low temperature or low density for the processing or concentration of liquid waste and process liquids, etc. to use. The transport and the work-up is in general associated with a considerable expenditure of energy of fossil origin, while on the other side not yet usable energy to the environment is delivered. As the processes of condensation and evaporation at atmospheric pressure can expire the devices of the invention be built without any special static requirements.

Die erfindungsgemäße Vorrichtung besteht aus einer mit bevorzugt durch Kondensation des Wassers aus feuchter Luft zu beheizenden Seite und einer durch Verdunstung flüchtiger Bestandteile wie Wasser oder Lösungsmittel kühlenden Seite, die durch eine wärmeübertragenden Wand voneinander getrennt sind. Der Prozess wird zum einen durch ständige Frischluftzufuhr auf der Verdunsterseite aufrechterhalten. Zum anderen besteht die Möglichkeit der externen Kühlung eines geschlossenen Luftkreislaufs auf der Verdunsterseite, wobei die verdunstete Flüssigkeit zur Kondensation gebracht und wieder verwendet werden kann. Mit diesen Verfahrensweisen können z. B. verdünnte Prozesslösungen wieder auf ein brauchbares Maß aufkonzentriert bzw. flüssige Abfälle in ihrer Menge reduziert werden. Allgemein kann auf der kühlenden Seite ein leicht flüchtiger Bestandteil eines Gemisches von einem schwerflüchtigen abgetrennt werden.The inventive device consists of one with preferably by condensation of the water moist air to be heated side and one by evaporation volatile Ingredients such as water or solvents cooling Side passing through a heat transferring Wall are separated from each other. The process is on the one hand by constant supply of fresh air maintained on the evaporator side. On the other hand there is the Possibility of external cooling a closed air circulation on the Verdunsterseite, where the evaporated liquid Condensed and reused. With these procedures can z. B. diluted process solutions again concentrated to a useful level or liquid scraps be reduced in their quantity. Generally can on the cooling Page a more volatile Part of a mixture to be separated from a nonvolatile.

Auf Grund der relativ großen Mengen zu bewegender Luft, wird die Vorrichtung bevorzugt als zylindrisch aufgebauter Kondensationsverdunster ausgeführt. Zur Verbesserung der Energieübertragung durch Kondensation wird der Gasstrom bevorzugt zwangsgeführt durch einen Mantel geleitet und das Kühlmedium an die Innenwand des Zylinders befördert. Zur Reinigung der Wärmeübertragungsflächen kann die Vorrichtung mit einer Reinigungseinrichtung versehen werden, so dass die Übertragung von Energie auf Medien ermöglicht wird, denen eine Verschmutzung von Wärmeübergangsflächen zu Eigen istOn Reason of the relatively large Amounts of air to be moved, the device is preferred as cylindrical constructed condensation evaporator executed. To improve the energy transfer through Condensation, the gas stream is preferably forcibly guided through passed a jacket and the cooling medium transported to the inner wall of the cylinder. To clean the heat transfer surfaces can the device is provided with a cleaning device, so that the transmission from energy to media which is subject to contamination of heat transfer surfaces
