Zylinderförmige Reaktoren aus Nickel bzw. Nickellegierungen zum Verbrennen von fluorhaltigen Kohlenstoffverbindungen sind bekannt. Die umzusetzenden Komponenten werden am Kopf der Reaktoren aufgegeben und die heißen Gase verlassen die Reaktoren an der entgegengesetzen Seite und werden über Leitungen einem Kühl- und Absorptionssytem zugeführt.Cylindrical reactors made of nickel or nickel alloys for burning fluorine-containing carbon compounds are known. The components to be converted are fed in at the top of the reactors and the hot gases leave the reactors on the opposite side and are fed to a cooling and absorption system via lines.

Der Erfindung liegt die Aufbage zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, der verkaufsfähige Flußsäure und/oder Salzsäure entnommen werden kann.The invention is based on the objective of creating a device of the type mentioned at the outset from which salable hydrofluoric acid and / or hydrochloric acid can be removed.

Die Aufgabe wird durch eine Vorrichtung gelöst, die dadurch gekennzeichnet ist, daß an einem Ende des Reaktors ein Brennersystem mit Zuführungen für ein Gemisch aus Fluor­kohlenwasserstoff und Brenngas sowie für Spülgas und Sauer­stoff bzw. Luft angeordnet ist, das stirnseitig eine Brenn­kammer begrenzt, die nahe dem Brennersystem mit einem Zünd­stutzen und Einrichtungen zum Zuführen und Verteilen von Flüssigkeit versehen ist, sich an die Brennkammer ein Absorber aus zylindrischen Blöcken mit Bohrungen parallel zur Reaktorachse für den flüssigen Produktstrom und das Gas anschließt, die in eine nachfolgende Ringkammer mün­den, die mit einem Stutzen zur Entnahme von Gas und Flüs­sigkeit versehen ist, und das andere Ende des Reaktors eine Öffnung zur Druckentlastung aufweist, die über einen Kanal mit der Brennkammer verbunden ist.The object is achieved by a device which is characterized in that a burner system with feeds for a mixture of fluorocarbon and fuel gas and for flushing gas and oxygen or air is arranged at one end of the reactor, which delimits a combustion chamber at the end, which is close to the Burner system is provided with an ignition nozzle and devices for supplying and distributing liquid, an absorber made of cylindrical blocks with holes parallel to the reactor axis for the liquid product stream and the gas connects to the combustion chamber, which open into a subsequent annular chamber, which with a nozzle for Removal of gas and liquid is provided, and the other end of the reactor has an opening for pressure relief, which is connected via a channel to the combustion chamber.

Der Reaktor kann mit einem Kühlmantel umgeben sein. Die parallel zur Reaktorachse verlaufenden Bohrungen können in radialer Richtung in Reihen angeordnet sein und die Blöcke zwischen benachbarten Reihen von Bohrungen Ausnehmungen aufweisen. Die Einlaufseite der Bohrungen kann mit Über­laufwehren versehen sein. Als Einrichtungen zum Zuführen und Verteilen von Flüssigkeit eignen sich in der Brenn­kammer angeordnete Sprühdüsen und Überlaufwehre. Zwischen Brennkammer und Absorber kann ein Flüssigkeitssammler mit Überlaufwehr für den Absorber angeordnet sein.The reactor can be surrounded by a cooling jacket. The bores running parallel to the reactor axis can be arranged in rows in the radial direction and the blocks have recesses between adjacent rows of bores. The inlet side of the holes can be provided with overflow weirs. Spray nozzles and overflow weirs arranged in the combustion chamber are suitable as devices for supplying and distributing liquid. A liquid collector with an overflow weir for the absorber can be arranged between the combustion chamber and the absorber.

Die durch die Erfindung erreichten Vorteile sind im wesent­lichen darin zu sehen, daß alle Fluorkohlenwasserstoff­typen, auch die nichtbrennbaren thermisch gespalten und die sehr korrosiven Spaltprodukte wie HF, HCl und Chlor als verkaufsfähige Produkte wie zum Beispiel Flußsäure und Salzsäure gewonnen bzw. ihre Entstehung, insbesondere die von Chlor verhindert werden können. Der Reaktor ist kom­pakt und gliedert sich in die drei Funktionsbereiche: Brennersystem, Brennkammer und Absorptionssystem.The advantages achieved by the invention are essentially to be seen in the fact that all types of fluorohydrocarbons, including the non-combustible ones, are thermally cracked and the very corrosive cracked products such as HF, HCl and chlorine are obtained as salable products such as hydrofluoric acid and hydrochloric acid or their formation, in particular the can be prevented by chlorine. The reactor is compact and is divided into three functional areas: burner system, combustion chamber and absorption system.

Im Folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigen:

  • Figur 1 den als Brennkammer dienenden Abschnitt (A) des erfindungsgemäßen rohrförmigen Reaktors teilweise ge­schnitten und
  • Figur 2 den als Absorber ausgebildeten Abschnitt (B) des Reaktors.
In the following, the invention is explained in more detail with the aid of drawings that illustrate only one embodiment. Show it:
  • Figure 1 partially serving as the combustion chamber section (A) of the tubular reactor according to the invention and
  • 2 shows the section (B) of the reactor designed as an absorber.

Das Brennersystem (1) ist am Kopf des Reaktors angeordnet und begrenzt stirnseitig die Brennkammer (2). Das Brennersystem kann als Drallbrenner ausgeführt sein. Über Leitung (3) wird das zu verbrennende Gas und Brenngas zu­geführt, über Leitung (4) Sauerstoff bzw. Luft. Das Bren­nersystem (1) ist von einem Gehäuse (5) umgeben und so im Reaktor ausgerichtet, daß die Flamme senkrecht von oben nach unten brennt. Über Leitungen (6) und (7) wird der In­nenraum des Gehäuses sowie das äußere des Gehäuses (5) mit Spülgas versorgt, das zusammen mit den Ringspalten (8; 8a); verhindern soll, daß korrosive Produkte zum Brenner­ system zurückströmen. Das Brennersystem kann aus Edelstahl oder beschichtetem Edelstahl hergestellt sein. Der Reak­tor besteht vorzugsweise aus Graphit. Der als Brennkam­mer (2) dienende Abschnitt (A) des Reaktors weist in der Nähe des Brennersystems einen Zündstutzen (9) zum Zünden der Flamme auf sowie Einrichtungen zum Zuführen und Ver­teilen von Flüssigkeit. Hierfür eignen sich Flüssigkeits­düsen (10), (11) und (12), mit deren Hilfe Flüssigkeit in die Brennkammer (2) eingedüst werden kann und/oder eine mit Überlaufwehr (14) versehene Rinne (13), die mittels Flüssigkeitsaufgabe (18) mit Flüssigkeit versorgt wird. Das Überlaufwehr (14) verteilt die Flüssigkeit als dünnen Film auf die Wand der Brennkammer (2). Zusätzlich kann die Brennkammer einen Kühlmantel (15) aufweisen, der mit Kühl­mittelzulauf (16) und Kühlmittelablauf (17) versehen ist. Ferner kann der die Brennkammer bildende Reaktorabschnitt (A) mit einer Inspektionsöffnung (19) und einem Tempera­turmeßstutzen (20) versehen sein. Die Länge der Brennkam­mer kann ein vielfaches, z.B. ein 5- bis 10-faches des Brennkammerdurchmessers betragen. An die Brennkammer (2) schließt sich ein als Absorber ausgebildeter weiterer Reak­torabschnitt (B) an. Der Absorber kann aus mehreren zylin­drischen Blöcken (21) bestehen, die mit parallel zur Reaktor­achse verlaufenden Bohrungen (22) versehen sind. In radia­ler Richtung können mehrere Bohrungen (22) zu einer Reihe hintereinander angeordnet sein und die Blöcke zwischen den Reihen der Bohrungen (22) mit radialen Ausnehmungen (23) zur Aufnahme von Kühlmittel versehen sein. Der den Absorber bildende Reaktorabschnitt (B) ist mit einem Kühlmantel (24) mit Kühlmittelzulauf (25) und Kühlmittelablauf (26) versehen. Zur Verbesserung der Turbulenz der Strömung und der Kühlmittelführung kann die Innenwand des Kühlmantels (24) mit ringförmigen Sperrsegmenten (30) versehen sein. Die Einlaufseite der Bohrungen (22) können Überlaufwehre (27) aufweisen. Die Bohrungen (22) des Absorbers münden in eine Ringkammer (28). Hier wird das Kondensat gesammelt und zu­sammen mit den Gasen über Stutzen (29) dem Reaktor entnom­ men. Der durch den Absorber und die innere Begrenzung (31) der Rinkammer (28) gebildete Kanal (32) dient der Druck­entlastung. Die Druckentlastungsöffnung 33 ist mit einer Druckentlastungseinrichtung, z.B. einer Berstscheibe oder einem Tauchverschluß verschlossen (nicht darstellt). Zwischen Brennkammer (2) und Absorber kann ein Flüssig­keitssammler (34) mit Überlaufwehr (35) angeordnet sein.The burner system (1) is arranged at the head of the reactor and delimits the combustion chamber (2) at the end. The burner system can be designed as a swirl burner. The gas and fuel gas to be burned are supplied via line (3) and oxygen or air via line (4). The burner system (1) is surrounded by a housing (5) and aligned in the reactor so that the flame burns vertically from top to bottom. The interior of the housing and the exterior of the housing (5) are supplied with purge gas via lines (6) and (7), which together with the annular gaps (8; 8a); should prevent corrosive products to the burner backflow system. The burner system can be made of stainless steel or coated stainless steel. The reactor is preferably made of graphite. The section (A) of the reactor, which serves as the combustion chamber (2), has an ignition nozzle (9) for igniting the flame in the vicinity of the burner system as well as devices for supplying and distributing liquid. For this purpose, liquid nozzles (10), (11) and (12) are suitable, with the aid of which liquid can be injected into the combustion chamber (2) and / or a channel (13) provided with an overflow weir (14), which can is supplied with liquid. The overflow weir (14) distributes the liquid as a thin film on the wall of the combustion chamber (2). In addition, the combustion chamber can have a cooling jacket (15) which is provided with a coolant inlet (16) and coolant outlet (17). Furthermore, the reactor section (A) forming the combustion chamber can be provided with an inspection opening (19) and a temperature measuring nozzle (20). The length of the combustion chamber can be a multiple, for example 5 to 10 times the diameter of the combustion chamber. A further reactor section (B) designed as an absorber adjoins the combustion chamber (2). The absorber can consist of several cylindrical blocks (21) which are provided with bores (22) running parallel to the reactor axis. A plurality of bores (22) can be arranged in a row in the radial direction and the blocks between the rows of bores (22) can be provided with radial recesses (23) for receiving coolant. The reactor section (B) forming the absorber is provided with a cooling jacket (24) with a coolant inlet (25) and coolant outlet (26). To improve the turbulence of the flow and the coolant flow, the inner wall of the cooling jacket (24) can be provided with annular blocking segments (30). The inlet side of the bores (22) can have overflow weirs (27). The bores (22) of the absorber open into an annular chamber (28). Here the condensate is collected and taken out of the reactor together with the gases via connection piece (29) men. The channel (32) formed by the absorber and the inner boundary (31) of the drinking chamber (28) serves to relieve pressure. The pressure relief opening 33 is closed (not shown) with a pressure relief device, for example a rupture disk or an immersion seal. A liquid collector (34) with an overflow weir (35) can be arranged between the combustion chamber (2) and the absorber.

Durch das einstellbare Flammenbild und die Kühlung der Brennkammerwand können bei der angestrebten schlanken Brennkammerausführung Wandtempraturen von unter 100°C er­reicht werden. Es ist daher möglich, Graphit, das gegen al­le Verbrennungsprodukte gut korrosionsbeständig ist, ein­zusetzen. Ein zusätzlicher Schutz gegen thermische und korrosive Zerstörung des Graphits bietet die Möglichkeit über ein Wehr, am Kopf der Brennkammer, Flüssigkeit aufzu­geben, vorzugsweise Wasser oder wäßrige Flußsäure, um einen Flüssigkeitsfilm auf der inneren Brennkammerwand zu erzeu­gen. Zusätzlich kann in die Brennkammer an verschiedenen Stellen Flüssigkeit eingespeist werden, vorzugsweise Wasser oder wäßrige Flußsäure, um die Flammentemperatur und das Reaktionsgleichgewicht einzustellen.Thanks to the adjustable flame pattern and the cooling of the combustion chamber wall, wall temperatures of less than 100 ° C can be achieved with the slim combustion chamber design. It is therefore possible to use graphite, which is well corrosion-resistant to all combustion products. Additional protection against thermal and corrosive destruction of the graphite offers the possibility of applying liquid, preferably water or aqueous hydrofluoric acid, via a weir to the top of the combustion chamber in order to produce a liquid film on the inner combustion chamber wall. In addition, liquid can be fed into the combustion chamber at various points, preferably water or aqueous hydrofluoric acid, in order to adjust the flame temperature and the reaction equilibrium.

Die Anordnung des Apparates ist senkrecht. Die Flammen­führung erfolgt von oben nach unten. Alle kondensierten Verbrennungsprodukte und zusätzlich aufgegebene Lösungsmen­gen - über Überlaufwehr oder Einspritzung - laufen von der Zone hoher Temperatur zur Zone niederer Temperatur und kön­nen am unteren Stutzen (29) gekühlt abgezogen werden. Der Kühlmittelstrom wird vorzugsweise im Gegenstrom dazu ge­führt.The arrangement of the apparatus is vertical. The flame is guided from top to bottom. All condensed combustion products and additional quantities of solution added - via overflow weir or injection - run from the high temperature zone to the low temperature zone and can be drawn off in a cool manner at the lower nozzle (29). The coolant flow is preferably carried out in counterflow.
