Die Vorrichtung besitzt eine Kondensatzuführungseinrichtung zum Zuführen des Kondensats in einen Brennraum des Verbrennungsmotors.The device has a condensate feed device for feeding the condensate into a combustion chamber of the internal combustion engine.
Die
Der zweite Teilwärmeübertrager weist Mittel auf, die ausgebildet sind, um das Abgas zu entfeuchten.The second partial heat exchanger has means which are designed to dehumidify the exhaust gas.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Gewinnung von Kondensat bereitzustellen, welche eine geringe Restfeuchte im Abgasmassenstrom aufweist.The invention has for its object to provide a device for recovering 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 obtaining 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 Abgasmassenstromleitung zu dem kühlen und trockenen Sorbens geleitet und von dem Sorbens adsorbiert.By means of the device according to the invention for the recovery of condensate contained in the pre-cooled down exhaust gas mass flow of water in the flow through the exhaust gas mass flow line to the cool and dry sorbent and adsorbed by the sorbent.
Die durch die Adsorption entstehende Wärme wird über den thermischen Leiter an das die erste Kühlmittelleitung durchströmende Kühlmittel abgeführt.The heat produced by the adsorption is dissipated via the thermal conductor to the coolant flowing through the first coolant line.
Anschließend durchströmt ungekühlter/heißer Abgasmassenstrom die 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 exhaust gas mass flow line.
There is a heat transfer from the exhaust gas mass flow to the sorbent.
The stored in the sorbent water is dissolved out by the exhaust heat from the sorbent and flows due to pressure differences to the condenser, which receives the water dissolved out.
In dem Kondensator kühlt das herausgelöste Wasser aufgrund des thermischen Kontaktes mit dem Kühlmittel, welches die erste Kühlmittelleitung durchströmt, ab und das dabei gewonnene Kondensat kann aus dem Kondensator herausströmen.In the condenser, the leached water cools due to the thermal contact with the coolant flowing through the first coolant line, and the condensate thereby obtained can flow out of the condenser.
In einer vorteilhaften Ausführungsform der Erfindung ist die des Sorbens regelbar.In an advantageous embodiment of the invention, that of the sorbent is controllable.
In einer weiteren vorteilhaften Ausführungsform der Erfindung weist die Vorrichtung eine zweite Kühlmittelleitung auf, die einen thermischen Kontakt zu der Abgasmassenstromleitung 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 second coolant line, which has a thermal contact with the exhaust gas mass flow line.
Hereby, a cooling of the exhaust gas mass flow is independent of the adsorption and desorption possible.
