Abstract

Chimney attachment for reducing carbon dioxide from gas-fired plants consists of a housing (2) with filter (8) and flue gas pipe (7) and a second housing (1) with baffle plate (3), runoff gutter (4) and spray nozzle (15).

Description

Vor der Beschreibung der möglichen anwendungstechnischen Konstruktionen soll zunächst die chemische Grundlage erläutert werden.Before describing the possible application engineering constructions first the chemical basis is explained.

Durch Brennen von Naturkalk CaCO3 wird das darin enthaltene Kohlendioxid ausge­ trieben, und es entsteht Calciumoxid CaO, der Branntkalk.By burning natural lime CaCO 3 , the carbon dioxide contained therein is expelled, and calcium oxide CaO, the quick lime, is formed.

Durch Löschen mit Wasser entsteht Calciumhydroxid Ca(OH)2, der gelöschte Kalk. Gibt man mehr Wasser zu, als für die Reaktion zu Ca(OH)2 notwendig ist, setzt sich Kalkwasser ab. Aus der Literatur ist bekannt, und eigene Versuche haben das bestä­ tigt, daß dieses Kalkwasser bis zu einem bestimmten Grad die gleichen chemischen Eigenschaften hat, wie der gelöschte Kalk Ca(OH)2. Somit kann das Kalkwasser auch als Ca(OH)2 bezeichnet werden.When extinguished with water, calcium hydroxide Ca (OH) 2 is created , the extinguished lime. If more water is added than is necessary for the reaction to Ca (OH) 2 , lime water will settle. It is known from the literature, and our own experiments have confirmed that this lime water has to a certain extent the same chemical properties as the hydrated lime Ca (OH) 2 . The lime water can therefore also be referred to as Ca (OH) 2 .

Leitet man nun Kohlendioxid CO2 durch das Kalkwasser Ca(OH)2, so entsteht das Ausgangsprodukt CaCO3, der Naturkalk.If you pass carbon dioxide CO 2 through the lime water Ca (OH) 2 , the starting product is CaCO 3 , the natural lime.

ReaktionsgleichungReaction equation

Brennen: 42,7 kcal + CaCO3 Burning: 42.7 kcal + CaCO 3

<<< CaO + CO2 <<< CaO + CO 2

<<<
Löschen: CaO + H2 <<<
Delete: CaO + H 2

O <<< Ca(OH)2
O <<< Ca (OH) 2

Reaktion mit CO2 Reaction with CO 2

: Ca(OH)2 : Ca (OH) 2

<<< CaCO3 <<< CaCO 3

Da das Ausgangs- und Endprodukt, also CaCO3, gleich ist, wäre ein technisch funk­ tionierender Kreislauf möglich. Since the starting and end product, i.e. CaCO 3 , is the same, a technically functioning cycle would be possible.

Anwendungstechnische Möglichkeit, wie in der Zeichnung dargestelltApplication technology possibility, as shown in the drawing

Das Gerät besteht im wesentlichen aus einem runden, oder quadratischen Gehäuse (2). Im Gehäuse (2) befinden sich die Reaktionskammer (1) mit Prallplatte (3) und Ablaufrinne (4), Einspritzdüse (15) und Abgasrohr (7) mit Filter (8).The device essentially consists of a round or square housing ( 2 ). The reaction chamber ( 1 ) with baffle plate ( 3 ) and drainage channel ( 4 ), injection nozzle ( 15 ) and exhaust pipe ( 7 ) with filter ( 8 ) are located in the housing ( 2 ).

Funktionfunction

Mit einer starken Elektro-Magnet-Dosierpumpe (12), die über den Wärmefühler (14) im Kamin (10) den Betriebskontakt erhält, wird Kalkwasser Ca(OH2) durch die Dosierleitung (6) in die Einspritzdüse (15) gedrückt. Von der Einspritzdüse (15) gelangt das Kalkwasser unter hohem Druck auf die Prallplatte (3), und wird dort durch den hohen Aufpralldruck zerstäubt.Lime water Ca (OH 2 ) is pressed through the metering line ( 6 ) into the injection nozzle ( 15 ) using a strong electro-magnetic metering pump ( 12 ), which receives the operating contact via the heat sensor ( 14 ) in the chimney ( 10 ). The lime water reaches the baffle plate ( 3 ) under high pressure from the injection nozzle ( 15 ) and is atomized there by the high impact pressure.

Alternativ kann die Einspritzdüse auch als Zerstäuberdüse ausge­ bildet sein. Die Reaktionsprodukte CaCO3 und Wasser fließen über die Rinne (4) und das Abflußrohr (5) in den Tank (11).Alternatively, the injection nozzle can also be formed as an atomizer nozzle. The reaction products CaCO 3 and water flow through the channel ( 4 ) and the drain pipe ( 5 ) into the tank ( 11 ).

Da auch noch im Gehäuse (2) eine Reaktion, wie vor beschrieben, stattfindet, ist für das Abfließen des Reaktionswassers der Abfluß (13) vorgesehen. Der Deckel (9) ist für die regelmäßigen Reinigun­ gen gedacht, wobei auch der erforderliche Filterwechsel (8) vorgenommen werden kann.Since a reaction, as described before, also takes place in the housing ( 2 ), the outflow ( 13 ) is provided for the outflow of the water of reaction. The lid ( 9 ) is intended for regular cleaning, whereby the required filter change ( 8 ) can also be carried out.
