Description
Die folgende Beschreibung beschreibt und bestimmt die Beschaffenheit der vorliegenden Erfindung und die Art und Weise, auf die sie durchzuführen ist:The following description describes and determines the nature of the present invention and the manner in which it is to be accomplished:
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung bezieht sich auf eine Trägeranordnung für ein System zur selektiven katalytischen Reduktion.The present invention relates to a carrier assembly for a selective catalytic reduction system.
Hintergrund der ErfindungBackground of the invention
Ein System zur selektiven katalytischen Reduktion ist eine Technologie, die bei Dieselmotoren zur Reduzierung von NOx-Emissionen unter Einsatz einer chemischen Reaktion zwischen einer wässrigen Harnstofflösung und Abgas eingesetzt wird. Der Hydraulikkreis des Systems zur selektiven katalytischen Reduktion besteht aus einem Speichertank, einer Pumpe, Filtern, Ventilen, einem Schlauch und einer Sprühvorrichtung und wässriger Harnstofflösung als Arbeitsmedium. Im Allgemeinen pumpt das Zufuhrmodul das Arbeitsmedium zu dem Dosierungsmodul. Vor dem Pumpen des Arbeitsmediums wird das Arbeitsmedium gefiltert, um sicherzustellen, dass sauberes Arbeitsmedium dem Dosierungsmodul zugeführt wird. Der Hauptfilter ist dauerhaft an der Trägeranordnung, die den Pegelsensor hält, fixiert oder damit verschweißt. Die Trägeranordnung ist an den Tank angebaut. Bei Bedingungen von Temperaturen unter null gefriert das Arbeitsmedium und somit ist eine Heizvorrichtung zum Erwärmen des Arbeitsmediums und zur Sicherstellung der Zufuhr von Arbeitsmedium zu dem Zufuhrmodul erforderlich.A selective catalytic reduction system is a technology used in diesel engines to reduce NOx emissions using a chemical reaction between an aqueous urea solution and exhaust gas. The hydraulic circuit of the selective catalytic reduction system consists of a storage tank, a pump, filters, valves, a hose and a spray device, and aqueous urea solution as a working medium. Generally, the delivery module pumps the working fluid to the dosing module. Prior to pumping the working fluid, the working fluid is filtered to ensure that clean working fluid is supplied to the dosing module. The main filter is permanently attached to the carrier assembly which holds, fixes or welds the level sensor. The carrier assembly is attached to the tank. At temperatures below zero, the working fluid freezes and thus a heater is required to heat the working fluid and to ensure the supply of working fluid to the delivery module.
