Description

Rauchgas-Entstaubungsanlage Die Erfindung betrifft eine -Pauchgas-Entstaubungsanlage mit Naßentstaubung und. besteht darin, daß mit dem Einlaß und dem Ausfall des Rauchgasreinigers ein Wärmeaustauscher so verbunden -ist, daß ihn als wärmeabgebendes Mittel das Rohgas und als wärmeaufnehmendes Mittel das Reißgas durchströmt.Flue gas dedusting system The invention relates to a flue gas dedusting system with wet dedusting and. is that with the inlet and failure of the flue gas cleaner A heat exchanger is connected in such a way that it uses the raw gas as a heat-emitting agent and the tear gas flows through it as a heat-absorbing agent.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar veranschaulichen die in .zwei verschiede=. nen Schnittlinien gezeichneten Abt). i und 2 einen Naßentstaubungsapparat bekannter Bauart, dem erfindungsgemäß ein Wärmeaus-Lauscher vorgeschaltet ist.In the drawing, the invention is shown in an exemplary embodiment, namely illustrate the in .two different =. cut lines drawn Abbot). i and 2 a wet dedusting apparatus of known type, according to the invention a heat exchanger is connected upstream.

Die Wirkungsweise ist folgende: Die ankommenden staubhaltigen Gase `gehen durch den Einlaßstutzen bin einen beispielsweise als Röhrenlufterhitzer ausgebildeten Wärmeaustauscher d; sie durchströmen unter Wärmeabgabe die Wärineaustauscherröhren c und werden durch den Auslaßstutzen d über eine kurze Leitung in den Einlaßstutzen e des Naßentstaubers t' geleitet. Hier treten sie etwa durch ein Naßfilter g bekannter Bauart, das' mittels einer - in- der Zeichnung nicht dargestellten Wasserleitung berieselt ist. Der ausgewaschene Staub'-Samt dem Wasser wird in einer unterhalb des Filters g angeordneten Schlammäbführungseinrichtung aufgefangen und der Kläranlage zugeleitet; die gröberen Staubteilchen, welche sich vor Durchtritt durch das Filter infolge Zentrifugierung abgeschieden haben, werden trocken durch. eine -besondere Auffangvorrichtung abgeleitet.. Die gereinigten und . durch das- Wasser zugleich- weiter gekühlten Gase durchstreichen nun. nochmals den Wärmeaustauscher a, der unmittelbar an den Au9laßstutzen h des Reinigers-angeschlossen ist, und zwar,gehen sie- jetzt um die Wärmeaustauscherrohre c herum. Sie nehmen also Wärme von den -die-Rohre c- durchziehenden heißen Rohgasen auf. Durch dies Abkühlen und Wiedererwärmen der Rauchgase, wird einerseits das Gasvolumen im Reiniger ver-. fingert, so daß "für. eine bestimmte Gasmenge ein kleinerer Reiniger verwandt werden kann, anderseits werden die mit -den Brüden des Waschwassers vermischten `abziehenden reinen Gase erwärmt, wodurch das - unerwünschte Auftreten vors Schwitzwasser in unmittelbarer Nähe des Entstaubers. verhindert wird. Ferner ermäßigt sich der Spülwasserverbrauch der Filter. infolge. der durch die niedrigere Temperatur -der Gase bedingten geringeren Wasserverdampfung.The mode of action is as follows: The incoming dusty gases `go through the inlet port, for example, a tubular air heater Heat exchanger d; they flow through the heat exchanger tubes, giving off heat c and are passed through the outlet port d via a short line into the inlet port e of the wet deduster t 'passed. Here they pass through a wet filter g better known Type of construction 'by means of a water pipe not shown in the drawing is sprinkled. The washed-out dust 'velvet the water is in a below the filter g arranged Schlammäbführungseinrichtung collected and the sewage treatment plant forwarded; the coarser dust particles, which are before passing through the filter deposited as a result of centrifugation, become dry through. a special Collection device derived .. The cleaned and. through the water at the same time further cooled gases are now crossed out. again the heat exchanger a, which is immediately is connected to the outlet port h of the cleaner, namely, go now around the heat exchanger tubes c. So they take heat from the -the-pipes c- permeating hot raw gases. By cooling and reheating the flue gases, on the one hand, the gas volume in the cleaner is used. fingers so that "for. a certain Gas quantity a smaller cleaner can be used, on the other hand the with -the vapors of the washing water mixed `exhausting pure gases are heated, whereby the - undesirable occurrence of condensation water in the immediate vicinity of the dust extractor. is prevented. Furthermore, the flushing water consumption of the filters is reduced. as a result. the lower water evaporation caused by the lower temperature of the gases.
