Aufgabe der vorliegenden Erfindung ist es, die aus der
Der Kern der vorliegenden Erfindung liegt in der Verwendung des angereicherten Abwassers aus der Ladeluftbefeuchtung für die Abgaswäsche. Durch dessen Alkalität erhöht sich die Effizienz der Abgaswäsche, wodurch der Reduktionsmitteleinsatz vorteilhafterweise verringert werden kann. Dies kann zu einer Verringerung von Baugröße und damit Anlagengewicht und/oder zu einem verringerten Chemikalieneinsatz genutzt werden, was nicht nur die Investitions- und Betriebskosten senken, sondern auch die Umwelt schonen kann.The essence of the present invention is the use of the enriched waste water from the charge air humidification for the exhaust scrubbing. Due to its alkalinity, the efficiency of the exhaust gas scrubbing increases, as a result of which the use of reducing agent can be advantageously reduced. This can be used to reduce the size and thus plant weight and / or reduced use of chemicals, which not only reduce the investment and operating costs, but can also protect the environment.
Eine Luftführungsvorrichtung nach der vorliegenden Erfindung dient zur Zufuhr von Verbrennungsluft und Abfuhr von Abgasen einer aufgeladenen Brennkraftmaschine wie beispielsweise eines großen Dieselmotors, insbesondere eines Schiffsdiesels. Sie umfasst einen Abgasturbolader mit einem Kompressor zum Verdichten von Luft, insbesondere angesaugter Frischluft, zu Ladeluft für die Brennkraftmaschine und einer von Abgas der Brennkraftmaschine antreibbaren Turbine, die ihrerseits, bevorzugt direkt, den Kompressor antreibt und so den Wirkungsgrad der Brennkraftmaschine erhöht.An air guiding device according to the present invention is used for supplying combustion air and exhaust gases of a supercharged internal combustion engine such as a large diesel engine, in particular a marine diesel. It comprises an exhaust-gas turbocharger with a compressor for compressing air, in particular fresh air drawn in, for charge air for the internal combustion engine and a turbine which can be driven by exhaust gas of the internal combustion engine, which in turn drives the compressor, preferably directly, and thus increases the efficiency of the internal combustion engine.
In einem Ladeluftbefeuchter, der zwischen Kompressor und den Brennräumen der Brennkraftmaschine angeordnet sein kann, wird flüssiges und/oder verdampftes See- bzw. Meerwasser zugeführt, beispielsweise eingedüst bzw. -spritzt, um die Ladeluft vom Kompressor zu kühlen und teilweise zu reinigen.In a charge air humidifier, which may be arranged between the compressor and the combustion chambers of the internal combustion engine, liquid and / or vaporized seawater or seawater is supplied, for example, injected or -spritzt to cool the charge air from the compressor and partially clean.
In einem Wasserabscheider wird wenigstens ein Teil des zugeführten Seewassers als Abwasser wieder abgeführt, wobei die Ladeluft einen Teil des Seewassers als wenigstens teilweise gesättigte- oder übersättigte Luft in die Brennräumen der Brennkraftmaschine eintragen kann, um dort lokale Verbrennungstemperaturspitzen und damit der Anteil thermisch gebildeten Stickoxids abzusenken.In a water separator at least a portion of the supplied seawater is discharged as wastewater again, the charge air can enter a portion of the seawater as at least partially saturated or supersaturated air in the combustion chambers of the internal combustion engine to lower there local combustion temperature peaks and thus the proportion of thermally formed nitrogen oxides ,
Dieses Abwasser, welches durch den Kontakt mit der heißen Ladeluft teilweise destilliert und angereichert sein kann, wird in einer bevorzugten Ausführung in einem Wärmetauscher zum Erwärmen, Verdampfen und/oder Überhitzen von frischem Seewasser genutzt, welches anschließend dem Ladeluftbefeuchter zugeführt wird.This wastewater, which may be partially distilled and enriched by contact with the hot charge air, is used in a preferred embodiment in a heat exchanger for heating, vaporizing and / or superheating fresh seawater, which is then supplied to the charge air humidifier.
Durch eine geeignete Einrichtung, die eine oder mehrere Leitungen, entsprechende Steuer- bzw. Regelventile und/oder eine oder mehrere Pumpen aufweisen kann, wird dieses angereicherte, alkalische Abwasser aus dem Ladeluftbefeuchter in einen Abgaswäscher eingespeist, der zur Reinigung, insbesondere zur nassen Rauchgasentschwefelung, von Abgas von der Brennkraftmaschine dient.By means of a suitable device, which may have one or more lines, corresponding control valves and / or one or more pumps, this enriched, alkaline waste water from the charge air humidifier is fed into an exhaust gas scrubber, which is used for cleaning, in particular for wet flue gas desulphurisation. of exhaust gas from the internal combustion engine is used.
Auf diese Weise kann Abwasser aus dem Ladeluftbefeuchter in dem Abgaswäscher erneut verwendet und so dessen Effizienz gesteigert werden. Vorteilhafterweise kann so auch eine separate Ansaugung von Seewasser für den Abgaswäscher oder eine eigene Ableitung für Abwasser von dem Ladeluftbefeuchter entfallen, so dass vorteilhaft weniger Ventile, Pumpen, Filter und dergleichen benötigt werden.In this way, wastewater from the charge air humidifier can be reused in the scrubber and thus its efficiency can be increased. Advantageously, a separate intake of seawater for the exhaust gas scrubber or a separate discharge for waste water from the charge air humidifier can thus also be omitted, so that advantageously fewer valves, pumps, filters and the like are required.
In einer bevorzugten Ausführung sind ein oder mehrere Sammler für Seewasser vorgesehen, wobei dieses durch wenigstens eine erste Pumpe in einen Sammler gefördert werden kann. Wenigstens eine zweite Pumpe kann Seewasser aus einem Sammler in den Ladeluftbefeuchter fördern. Wenigstens eine dritte Pumpe kann zum Fördern von Abwasser aus einem Sammler in den Abgaswäscher vorgesehen sein. Hierdurch können die Seewassermengen in Sammler, Ladeluftbefeuchter und Abgaswäscher geeignet, gegebenenfalls auch unabhängig voneinander, reguliert werden.In a preferred embodiment, one or more collectors are provided for seawater, which can be conveyed by at least a first pump in a collector. At least one second pump can feed seawater from a collector into the charge air humidifier. At least one third pump may be provided for pumping wastewater from a collector into the scrubber. As a result, the quantities of seawater in the collector, charge air humidifier and exhaust gas scrubber can be suitably regulated, if appropriate also independently of one another.
Bevorzugt umfassen der bzw. die Sammler den vorstehend erläuterten Wärmetauscher, um frisches Seewasser durch die vom Abwasser aus der komprimierten und dadurch erwärmten Ladeluft ausgetragenen Wärme vorzuwärmen bzw. zu verdampfen oder zu überhitzen. Dieser Wärmetauscher kann vorzugsweise im Gleich-, Gegen- oder Kreuzstrom betrieben werden.Preferably, the collector (s) comprise the above-described heat exchanger for preheating, evaporating or overheating fresh seawater by the heat discharged from the waste water from the compressed and thereby heated charge air. This heat exchanger can preferably be operated in DC, counter or cross flow.
In einer bevorzugten Ausführung ist ein Bypass bzw. eine Passage von einer ersten Pumpe zu dem Abgaswäscher zur Umgehung des Ladeluftbefeuchters vorgesehen, um gegebenenfalls Seewasser, wenigstens anteilig, auch ohne Durchlaufen der Ladeluftbefeuchtung, insbesondere unter Umgehung eines Wärmetausches, als Waschwasser dem Abgaswäscher zuleiten zu können. Vorzugsweise ist ein solcher Bypass durch ein oder mehrere Steuer- bzw. Regelventile absperrbar.In a preferred embodiment, a bypass or a passage from a first pump to the exhaust scrubber to bypass the charge air humidifier is provided to possibly sea water, at least partially, even without passing through the Ladeluftbefeuchtung, especially while bypassing a heat exchange, to forward to the scrubber as scrubbing water , Preferably, such a bypass can be shut off by one or more control valves.
Zusätzlich oder alternativ kann eine Zufuhreinrichtung zur Zufuhr von zusätzlichem Waschwasser, insbesondere Frischwasser, zu dem Abgaswäscher vorgesehen sein. Eine solche Zufuhreinrichtung weist bevorzugt wenigstens eine Pumpe zur Förderung des Waschwassers und/oder ein oder mehrere Steuer- bzw. Regelventile zum Absperren der Zufuhr auf und ist bevorzugt stromabwärts nach dem Ladeluftbefeuchter, insbesondere stromabwärts von einem Sammler und/oder Wärmetauscher angeordnet, um eine von der Ladeluftbefeuchtung unabhängige Waschwasserzufuhr oder Zumischung zu Abwasser aus der Ladeluftbefeuchtung darzustellen.Additionally or alternatively, a supply device for supplying additional washing water, in particular fresh water, may be provided to the exhaust gas scrubber. Such a supply device preferably has at least one pump for conveying the washing water and / or one or more control valves for shutting off the supply and is preferably arranged downstream of the charge air humidifier, in particular downstream of a collector and / or heat exchanger, to one of the charge air humidification to represent independent washing water supply or admixture to waste water from the charge air humidification.
Insbesondere, wenn ein Bypass und/oder eine Zufuhreinrichtung zur Zufuhr von zusätzlichem Waschwasser vorgesehen ist, können ein oder mehrere Steuer- bzw. Regelventile zwischen dem Ladeluftbefeuchter und dem Abgaswäscher, insbesondere stromabwärts nach einem Sammler und/oder Wärmetauscher angeordnet sein, um wahlweise auch eine Abgaswäsche ohne Verwendung oder unter Zumischung von Abwasser aus der Ladeluftbeuchtung zu ermöglichen.In particular, if a bypass and / or a supply device for supplying additional washing water is provided, one or more control valves can be arranged between the charge air humidifier and the exhaust gas scrubber, in particular downstream of a collector and / or heat exchanger, optionally also one Waste gas scrubbing without use or admixed with wastewater from the charge air to allow.
Bevorzugt ist eine Ableiteinrichtung zur Ableitung von Abwasser aus dem Abgaswäscher mit einer Ableitung von Abwasser aus dem Ladeluftbefeuchter verbunden, um so den apparativen Aufwand weiter zu reduzieren.Preferably, a discharge device for discharging wastewater from the exhaust gas scrubber is connected to a discharge of waste water from the charge air humidifier, so as to further reduce the expenditure on equipment.
Ein mit Abwasser aus der Ladeluftbefeuchtung speisbarer Abgaswäscher kann zur Reinigung von in die Umgebung abgegebenes Abgas und/oder zur Reinigung von Abgas dienen, welches der Verbrennungsluft vor oder nach deren Verdichtung im Kompressor des Abgasturboladers zugeführt wird.An exhaust gas scrubber which can be fed with waste water from the charge air humidification can be used to purify exhaust gas emitted into the environment and / or to purify exhaust gas which is supplied to the combustion air before or after its compression in the compressor of the exhaust gas turbocharger.
