Process and apparatus for purifying waste gases
Abstract
Das Verfahren und die Vorrichtung zum Reinigen von beim Verbrennungsvorgang entstehenden Abgasen von Feuerungsanlagen benutzt einen Wärmetauscher (12), durch den zunächst die den Feuerungsbereich verlassenden hocherhitzten Abgase (17) hindurchströmen. Dabei werden die Abgase (17) derart abgekühlt, daß nachfolgend in einem Kondensator (13) der Taupunkt der Abgase (17) unterschritten wird, so daß nachfolgend der Wasseranteil der Abgase (17) unter gleichzeitiger Bindung des Schadstoffanteils ausfällt. Nachfolgend werden die schadstoffverminderten Abgase (17) zur Nachreinigung einer Einrichtung (16) zugeführt, die diese mit Wasser (18) besprüht. Die gereinigten Abgase (17) dienen anschließend im Wärmetauscher als Kühlmittel der dem Wärmetauscher zugeführten hocherhitzten Abgase, die unmittelbar von der Feuerungsanlage kommen und somit abgekühlt werden. Die durch diesen Wärmeaustauschvorgang erwärmten gereinigten Abgase werden nachfolgend an die Umgebung abgegeben.
