Aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Gewinnung von Kondensat bereitzustellen, welche eine ein geringe Restfeuchte im Abgasmassenstrom aufweist.The invention has for its object to provide a device for the production of condensate, which has a low residual moisture in the exhaust gas mass flow.
Lösung der AufgabeSolution of the task
Die Erfindung wird durch eine Vorrichtung zur Gewinnung von Kondensat gemäß Anspruch 1 gelöst.The invention is achieved by a device for extracting condensate according to
Vorteile der ErfindungAdvantages of the invention
Mittels der erfindungsgemäßen Vorrichtung zur Gewinnung von Kondensat wird das im vorab heruntergekühlten Abgasmassenstrom enthaltene Wasser bei der Durchströmung der zweiten Abgasmassenstromleitung zu dem kühlen und trockenen Sorbens geleitet und von dem Sorbens adsorbiert.
Die durch die Adsorption entstehende Wärme wird über den thermischen Leiter an das die Kühlmittelleitung durchströmende Kühlmittel abgeführt.By means of the device for obtaining condensate according to the invention, the water contained in the previously cooled exhaust gas mass flow is passed to the cool and dry sorbent as it flows through the second exhaust gas mass flow line and is adsorbed by the sorbent.
The heat generated by the adsorption is dissipated via the thermal conductor to the coolant flowing through the coolant line.
Anschließend durchströmt ungekühlter/heißer Abgasmassenstrom die erste Abgasmassenstromleitung.
Es erfolgt eine Wärmeübertragung von dem Abgasmassenstrom auf das Sorbens.
Das in dem Sorbens eingelagerte Wasser wird durch die Abgaswärme aus dem Sorbens herausgelöst und strömt aufgrund von Druckunterschieden zu dem Kondensator, welcher das das herausgelöste Wasser aufnimmt.Subsequently, uncooled / hot exhaust gas mass flow flows through the first exhaust gas mass flow line.
Heat is transferred from the exhaust gas mass flow to the sorbent.
The water stored in the sorbent is released from the sorbent by the exhaust gas heat and flows due to pressure differences to the condenser, which absorbs the water released.
In dem Kondensator kühlt das herausgelöste Wasser aufgrund des thermischen Kontaktes mit dem Kühlmittel, welches die Kühlmittelleitung durchströmt, ab und das dabei gewonnene Kondensat kann aus dem Kondensator herausströmen.The dissolved water cools in the condenser due to the thermal contact with the coolant which flows through the coolant line, and the condensate obtained in the process can flow out of the condenser.
In einer vorteilhaften Ausführungsform der Erfindung ist die Durchströmung der ersten und zweiten Abgasmassenstromleitung regelbar.In an advantageous embodiment of the invention, the flow through the first and second exhaust gas mass flow lines can be regulated.
In einer weiteren vorteilhaften Ausführungsform der Erfindung weist die Vorrichtung eine dritte Abgasmassenstromleitung auf, die einen thermischen Kontakt zu der Kühlmittelleitung aufweist.
Hiermit ist eine Kühlung des Abgasmassenstromes unabhängig von der Ad- und Desorption möglich.In a further advantageous embodiment of the invention, the device has a third exhaust gas mass flow line which has thermal contact with the coolant line.
This allows the exhaust gas mass flow to be cooled independently of the adsorption and desorption.
