Description
Bei der Reinigung von Hochofengichtgasen werden diese nach dem sogenannten Naß-, reihigungsverfahren mit Wasser in Apparaten in Verbindung gebracht, . einerseits zu dem Zwecke der Abkühlung, anderseits zu dem Zwecke der Durchfeuchtung des Gases, um die in den Gasen enthaltenen Staubteilchen durch Feuchtigkeit zu beschweren, damit dieselben infolge ihrer spezifischen Schwere aus dem Gässtrom ausgefällt werden.When cleaning blast furnace top gases, these are so-called wet, sequential processes associated with water in apparatus,. on the one hand to that For the purpose of cooling, on the other hand for the purpose of moistening the gas in order to achieve the To weigh down dust particles contained in the gases by moisture, so that the same due to their specific gravity are precipitated from the gas stream.
Bei der sogenannten Trockenreinigung wird das Gas durch Filter filtriert und zur Ausscheidung des Wasserdampfes mit Wasser in Berührung gebracht. In beiden Fällen wird also Wasser verwendet. Da nun aber in den Gasen auch Kohlensäure-enthalten ist, welche bei der Verbrennung hinderlich ist, so wird nach diesem bisherigen Verfahren nur eine Ausscheidung von Bestandteilen auf mecha-With so-called dry cleaning, the gas is filtered through a filter and separated out of the water vapor brought into contact with water. So in both cases water is used. But now in the Gases also contain carbonic acid, which in the combustion is a hindrance, so only one is according to this previous method Elimination of components on mechanical
ao nischem Wege bewirkt. Nun ist es zwar bekannt, die Kohlensäure aus Gasen mittels chemischer Lösung, beispielsweise Kalkmilch, auszuscheiden, indem die betreffenden Gase in geeigneten Apparaten mit dieser Lösung behandelt werden.- Auch ist schon vorgeschlagen, diese Apparate zur Reinigung von Kraftgasen von der Kohlensäure, beispielsweise ',. Wassergas, zu benutzen. Während es in diesen Anwendungsfällen keine Rolle spielt, neben der 'Gaserzeugungsanlage noch einen Gas-ao nical way. Now it is indeed known to excrete carbon dioxide from gases by chemical solution such as lime milk by passing the gases in question werden.- treated in suitable apparatus with this solution, too, is already proposed, these apparatuses for purifying force gases from carbonic acid, for example ' ,. Water gas to use. While it does not matter in these applications, in addition to the 'gas generation plant, a gas
■ reinigungsapparat zur Ausscheidung der Koh-, lensäure aufzustellen., würde das gleiche Verfahren, auf Hochofengichtgase angewendet,■ cleaning device for the elimination of carbon, to set up oleic acid., would use the same procedure, applied to blast furnace top gases,
wegen der großen zu bewältigenden Gasmen- ■ gen Anlagekosten verursachen, die zu dem 35 erreichten Ergebnis im Mißverhältnis stehen würden. «due to the large quantities of gas that have to be handled, the result achieved would be disproportionate. «
Demgegenüber kennzeichnet sich das vor- · ι liegende Verfahren dadurch, daß die in an sich bekannter Weise zum Ausscheiden der 40 Kohlensäure aus Gasen dienende Kalk- oder andere Lösung demjenigen Wasser zugesetzt. wird, das in der sowieso, wie eingangs ange- / geben, notwendigen und vorhandenen Gaswascheranlage zur Kühlung und Gichtstaub- 45 ausscheidung mit dem Hochofengichtgas durch, Zirkulation in innige Berührung gebracht wird. Indem diese Apparate (Zentrifugalwäscher, ; Desintegratoren) bereits zum Zwecke der star- : ken Abkühlung der sehr heißen Hochofengase 50 und zur Ausscheidung der Gichtstaubmengen die Einrichtung für eine rege Zirkulation und ! innige Berührung des Wassers besitzen, ist es möglich, durch den Zusatz der Kalklösung : ; oder einer anderen geeigneten Lösung zu dem 55 , Reinigungswasser dieser Apparate, sie selbst, ..:.' ohne Aufwand von Mehrkosten durch Auf-- . stellung ^besonderer großer chemischer Reinigungsapparate, als solche zur Beseitigung der: ; Kohlensäure auszunutzen. Durch dieses Ver- 60 fahren erreicht man also in den vorhandenen . Apparaten zur Kühlung und mechanischen Staubreinigung gleichzeitig die Ausfällung:der Kohlensäure, so daß die Qualität der Gase : \ ί in bezug auf ihren Verbrennungswert erheblich 65 , gebessert wird.In contrast, the present process is characterized in that the lime or other solution used in a manner known per se to separate the carbonic acid from gases is added to that water. is that in the anyway, as stated / indicated, necessary and available gas scrubber system for cooling and blast furnace dust elimination with the blast furnace top gas through, circulation is brought into intimate contact.

With this method one can thus reach the existing ones.
