Description
Das Hauptpatent betrifft eine Vorrichtung zum Abscheiden von Kohlensäure aus Dampf, bei der der Dampf in einem Wäscher mit Lauge behandelt wird. Nach dem Hauptpatent sind bei Verwendung von Ablauge zur Wäsche der Waschkreislauf und der Verdampferkreislauf getrennt angeordnet, wobei, da die Aufnahmefähigkeit der Lauge beim Waschen naturgemäß durch die Umsetzung in Soda allmählich abnimmt, eine Erhöhung der Konzentration der Ablauge durch Zugabe von Fremdlauge vorgesehen ist. Erfindungsgemäß läßt sich die Waschlauge auf einfachem Wege und mit geringem Aufwand an Zusatzlauge dadurch regenerieren, daß sie einem Verdampfungsprozeß in einem besonderen Laugeverdampfer unterworfen wird. Dabei spaltet sich die Kohlensäure ab und entweicht mit dem Laugenbrüden. Eine solche Spaltung im Laugeverdampfer läßt sich durch geeignete Ausbildung der Trennvorrichtung verbessern. The main patent relates to a device for separating carbon dioxide from steam, in which the steam is treated with lye in a washer. After this The main patents are when using waste liquor for washing the washing cycle and the Evaporator circuit arranged separately, since the absorption capacity of the lye when washing naturally gradually decreases due to the conversion in soda, an increase the concentration of the waste liquor is provided by adding external liquor. According to the invention the washing liquor can be easily and with little expenditure of additional liquor regenerate by using an evaporation process in a special liquor evaporator is subjected. The carbon dioxide is split off and escapes with the lye vapor. Such a cleavage in the liquor evaporator can be achieved by suitable training of the Improve separation device.
Die Erfindung ist in der Zeichnung an einem Ausführungsbeispiel veranschaulicht. The invention is illustrated in the drawing using an exemplary embodiment.
Der im Verdampfer I entwickelte Dampf tritt aus einem Dampfraum I3 in einen Wäscher 3I. Er wird unter dem Spiegel der Waschlauge zugeführt; hierzu sind der Trennraum I3 und der unmittelbar darüberliegende Waschraum 3I durch eine Rohrschleife in Form eines zentral angeordneten Doppelrohres 32, 33 miteinander verbunden. Das innere, nach oben offene Rohr ist an den Trennbehälter I3 angeschlossen, während das äußere Rohr 33 an der unteren Mantelfläche Öffnungen 34 zum Eintritt des Dampfes in die Waschlauge aufweist. Der Dampf wird nach Hindurchtreten durch die Waschlauge noch durch ein Filter 21 geleitet, wo er von etwa mitgerissenen Laugeteilchen befreit wird. The vapor developed in the evaporator I emerges from a vapor space I3 into a washer 3I. It is added to the washing liquor under the mirror; For this are the separation space I3 and the immediately above washroom 3I by a Pipe loop in the form of a centrally arranged double pipe 32, 33 with one another tied together. The inner tube, which is open at the top, is connected to the separating container I3, while the outer tube 33 has openings 34 on the lower lateral surface for entry of the steam in the detergent solution. The steam is after passing through the washing liquor is passed through a filter 21, where it is removed from any entrained lye particles is released.
Die Waschlauge wird aus dem Wäscher einem Laugeverdampfer 35 zugeführt. Darin wird durch den Verdampfungsvorgang das Natriumbikarbonat (NaH C 03) in Natronlauge (Na O H) und Kohlensäure (CO2) aufgespalten. Die Kohlensäure entweicht mit einer geringen Brüdenmenge aus dem Laugeverdampfer, während die Natronlauge zum Wäscher zurückgeführt wird. The wash liquor is fed from the scrubber to a liquor evaporator 35. The evaporation process turns the sodium bicarbonate (NaH C 03) into sodium hydroxide solution (Na O H) and carbonic acid (CO2) split. The carbonic acid escapes with a small amount of vapor from the caustic evaporator, while the caustic soda to the scrubber is returned.
Der Laugeverdampfer ist, um eine starke Molekülbeanspruchung und damit eine wirksame Spaltung des Natriumbikarbonats zu erzielen, mit einem Zyklon 36 ausgerüstet. The caustic evaporator is to a strong molecular stress and to achieve effective splitting of the sodium bicarbonate with a cyclone 36 equipped.
Die Auffrischung der Waschlauge durch Verdampfung in einem Laugeverdampfer kann in der Weise geschehen, daß die Lauge in ständigem Kreislauf vom Wäscher zum Verdampfer und wieder zum Wäscher zurückfließt. Man kann aber auch die Reinigung der Lauge je nach Bedarf von Zeit zu Zeit vornehmen, insbesondere wird man in größeren Anlagen mit mehreren Verdampfern diesen einen gemeinsamen Laugewäscher zuordnen. The refreshment of the washing liquor by evaporation in a liquor evaporator can be done in such a way that the lye in constant circulation from the scrubber to Evaporator and flows back to the scrubber. But you can also do the cleaning Make the lye from time to time as needed, especially one in larger ones Assign systems with several evaporators to a common caustic washer.
Man kann dann Sammelbehälter für die verbrauchte und die gereinigte Lauge vorsehen, zwischen die der Laugeverdampfer eingeschaltet ist.You can then collect containers for the used and the cleaned Provide caustic between which the caustic evaporator is switched on.
Der Verdampfer selbst arbeitet zweckmäßig ohne Zyklon, um die Abspaltung dort möglichst niedrig zu halten. Der Trennraum ist entweder entsprechend hoch auszubilden, oder er kann auch, wie in der Zeichnung dargestellt, mit einer einfachen Haube zum Umlenken des Brüdens versehen sein. The evaporator itself works expediently without a cyclone to prevent the separation to keep there as low as possible. The separation space must either be designed to be correspondingly high, or, as shown in the drawing, it can also be used with a simple hood Redirecting the brother must be provided.
PATENTANSPROCHE: I. Vorrichtung zum Abscheiden von Kohlensäure aus Dampf, bei der der Dampf in einem Wäscher durch Lauge behandelt wird, nach Patent 966 o56, dadurch gekennzeichnet, daß zur Regenerierung der zum Waschen des Dampfes dienenden Lauge ein Laugeverdampfer (35) vorgesehen ist. PATENT CLAIM: I. Device for separating carbon dioxide from Steam, in which the steam is treated with lye in a washer, according to patent 966 o56, characterized in that for the regeneration of the washing of the steam Serving liquor a liquor evaporator (35) is provided.
