Description

Prozessgaskühler mit hebelgesteuerten Prozessgaskühlerklappen  Process gas cooler with lever-controlled process gas cooler flaps
[0001] Die vorliegende Erfindung betrifft hebelgesteuerte Prozessgaskühlerklappen, mit denen sich die durch einen Prozessgaskühler strömende Gesamtmenge eines Prozessgases variabel in mindestens zwei Ströme aufteilen lässt, die unterschiedlich stark abgekühlt werden, bevor sie vor dem Austritt aus dem Prozessgaskühler wieder zusammengemischt werden. Dazu sind die Prozessgaskühlerklappen an Wellen befestigt, deren Stellungen mittels Hebeln, Verbindungsstangen und einem durch den Druckmantel des Prozessgaskühlers nach außen geführten Antriebskörper gesteuert werden.  The present invention relates to lever-controlled process gas cooler flaps, with which the flowing through a process gas cooler total amount of a process gas can be variably divided into at least two streams that are cooled to different degrees before they are mixed together again before exiting the process gas cooler. For this purpose, the process gas cooler flaps are attached to shafts whose positions are controlled by means of levers, connecting rods and a guided through the pressure jacket of the process gas cooler to the outside drive body.
[0002] Prozessgaskühler dienen bei der Herstellung von Wasserstoff, Ammoniak, Alkenen oder Methanol nach dem Reformierprozess zum Abkühlen des Prozessgases. Diese Reforme- rierprozesse finden entweder ausschließlich in einem Röhrenspaltofen statt, in dem Kohlenwasserstoff mit Wasserdampf unter Druck katalytisch reformiert wird, oder es sind diesem Spaltofen noch weitere Reformierreaktoren nachgeschaltet. Das Produkt dieser Prozesse ist ein Synthesegas, hier wird es Prozessgas genannt. Die Austrittstemperaturen des Prozessgases liegen je nach Herstellungsprozess zwischen 520°C und 1000°C. Bevor das Prozessgas zur weiteren Prozesskette geleitet wird, muss es erst abgekühlt werden. Dies geschieht meistens mittels eines Prozessgaskühlers.  Process gas cooler are used in the production of hydrogen, ammonia, alkenes or methanol after the reforming to cool the process gas. These reforming processes take place either exclusively in a tube-gap furnace in which hydrocarbon is catalytically reformed with steam under pressure, or further reforming reactors are connected downstream of this cracking furnace. The product of these processes is a synthesis gas, here it is called process gas. Depending on the manufacturing process, the outlet temperatures of the process gas are between 520 ° C and 1000 ° C. Before the process gas is sent to the further process chain, it must first be cooled down. This usually happens by means of a process gas cooler.
[0003] Die Gemeinsamkeit der Prozessgaskühler der verschiedenen Herstellungsprozesse sind Wärmeübertragungsvorrichtungen und mindestens eine Bypassvorrichtung. Ein Teil des in den Prozessgaskühler eintretenden heißen Prozessgases wird über Wärmeübertragungsvorrichtung einem indirekten Wärmeaustausch mit einem Kühlmedium, meistens Wasser, unterzogen, wobei das Prozessgas dadurch abgekühlt wird, und der oder die anderen Teile des heißen Prozessgases strömen durch eine Bypassvorrichtung und werden dabei weniger oder nicht gekühlt. Wärmeübertragungs- und Bypassvorrichtung bestehen üblicherweise aus jeweils mindestens einem Rohr. The commonality of the process gas cooler of the various manufacturing processes are heat transfer devices and at least one bypass device. A part of the hot process gas entering the process gas cooler is subjected to indirect heat exchange with a cooling medium, mostly water, through heat transfer means, thereby cooling the process gas, and the other part of the hot process gas flows through a bypass device and becomes less or not cooled. Heat transfer and bypass device usually consist of at least one tube.
[0004] Daher verfügt der Prozessgaskühler über einen Druckmantel, innerhalb dessen der Prozessgaskühler in drei Bereiche eingeteilt werden kann: Einlassbereich, Wärmeübertragungsbereich und Auslassbereich. Auf der Einlassseite tritt heißes Prozessgas mit einer Temperatur mindestens 520°C in den Prozessgaskühler ein. Infolge der hohen Temperatur des durchströmenden Prozessgases weist der Einlassbereich innerhalb des Druckmantels eine Wärme isolierende Schicht auf. Zwischen dem Einlassbereich und dem Auslassbereich wird das Prozessgas teilweise abgekühlt. Das abgekühlte Prozessgas wird anschließend mit dem weniger oder nicht gekühlten aus dem Bypassrohr austretenden Prozessgas im Auslassbereich gemischt. Das gemischte Prozessgas hat beim Auslassbereich immer noch eine Temperatur von ca. 300°C bis 400°C. [0005] Um die Gasaustrittstemperatur eines Prozessgaskühlers in einem bestimmten Temperaturbereich zu halten, wird üblicherweise das Aufteilungsverhältnis des den Wärmeübertra- gungs- und den Bypassvorrichtungen zugeführten Prozeßgases geregelt. Im bisherigen Stand der Technik werden dafür Regelklappen, Regeldrehklappen oder Regelstopfen eingesetzt. Therefore, the process gas cooler has a pressure jacket, within which the process gas cooler can be divided into three areas: inlet area, heat transfer area and outlet area. On the inlet side, hot process gas enters the process gas cooler at a temperature of at least 520 ° C. As a result of the high temperature of the process gas flowing through, the inlet region within the pressure jacket has a heat-insulating layer. Between the inlet region and the outlet region, the process gas is partially cooled. The cooled process gas is then mixed with the less or not cooled emerging from the bypass tube process gas in the outlet. The mixed process gas still has a temperature of about 300 ° C to 400 ° C at the outlet. In order to keep the gas outlet temperature of a process gas cooler within a certain temperature range, the distribution ratio of the process gas supplied to the heat transfer and the bypass devices is usually controlled. In the prior art control valves, regulating flaps or control plugs are used for this purpose.
[0006] Durch Regelvorrichtungen wird das die Wärmeübertragungsrohre und die Bypass- rohre durchströmende Prozessgas im Auslassbereich gemischt und anschließend aus dem Prozessgaskühler ausgelassen.  By means of regulating devices, the process gas flowing through the heat transfer tubes and the bypass tubes is mixed in the outlet region and subsequently discharged from the process gas cooler.
[0007] Die Schrift DE 10 2005 057 674 A1 beschreibt einen Abhitzekessel, der innerhalb eines zylindrischen Mantels eine Vielzahl von Wärmeübertragungsrohren und ein zentrisch angeordnete Bypassrohr umfasst, wobei nur die Gasdurchtrittsgeschwindigkeit und -menge im Bypassrohr durch einen am Auslass des Bypassrohres angeordneten und mittels der Regeleinrichtung axial verstellbaren Stopfens geregelt wird.  The document DE 10 2005 057 674 A1 describes a waste heat boiler, which includes a plurality of heat transfer tubes and a centrally arranged bypass tube within a cylindrical shell, wherein only the gas passage velocity and quantity in the bypass tube arranged by a at the outlet of the bypass tube and by means of Regulating device axially adjustable plug is regulated.
[0008] Auch zum Gasabkühlen ist ein Rohrbündelwärmetauscher in DE 39 13 422 C3 offenbart, wobei der Rohrbündelwärmetauscher ebenfalls eine Vielzahl von Wärmeübertragungsrohren und ein zentrisch angeordnete Bypassrohr umfasst, und auf der Gasaustrittsseite sind Regelkammern vorgesehen, worin durch Wärmeübertragungsrohre gekühltes Gas mit dem durch das Bypassrohr nicht oder wenig gekühlte Gas gemischt wird, wobei die Gasdurchtritts- geschwindigkeiten und -mengen auf der Gasaustrittsseite durch an einem von außen betätigbaren Regelglied angeordnete drei Klappen gesteuert werden.  Also for gas cooling, a tube bundle heat exchanger is disclosed in DE 39 13 422 C3, wherein the tube bundle heat exchanger also includes a plurality of heat transfer tubes and a centrally arranged bypass tube, and on the gas outlet side control chambers are provided, wherein cooled by heat transfer tubes with the gas through the bypass tube not or little cooled gas is mixed, wherein the gas passage speeds and amounts are controlled on the gas outlet side by arranged on a externally operable control member three flaps.
[0009] Insbesondere die mittlere Regelklappe, die Gasdurchtrittsgeschwindigkeit und - menge im Bypassrohr regelt, verfügt über eine Kühlvorrichtung. Alle Regelklappen sind auf einer gemeinsamen Welle angeordnet. Da Regelglied, Regelklappen und die Regelkammern mit Prozessgasen oder Kühlmedien unterschiedlicher Temperatur in Kontakt sind und auch im Allgemeinen aus unterschiedlichen Werkstoffen bestehen, sind die thermischen Ausdehnungen dieser Bauteile nicht gleich. Infolge dieser verschiedenen Ausdehnungen kann es zu starken Kontakten zwischen Bauteilen kommen, die sich zur Funktion der Regeleinrichtung relativ zueinander bewegen können müssen. Starke Kontakte führen große Reibungskräfte nach sich, die die nötigen Bewegungen der Bauteile be- oder völlig verhindern. Begünstigt wird diese Fehlfunktion durch große starr zusammenhängende Bauteile, die in beweglichem Kontakt zu mehreren anderen Bauteilen mit jeweils unterschiedlicher Temperatur stehen.  In particular, the middle control valve, the gas passage speed and - regulates amount in the bypass tube, has a cooling device. All control valves are arranged on a common shaft. Since control element, control valves and the control chambers are in contact with process gases or cooling media of different temperatures and also generally consist of different materials, the thermal expansions of these components are not the same. As a result of these different dimensions, it can lead to strong contacts between components that must be able to move relative to each other to the function of the control device. Strong contacts cause large frictional forces, which prevent or completely prevent the necessary movements of the components. This malfunction is favored by large rigidly connected components which are in moving contact with several other components, each with a different temperature.
[0010] Es besteht daher den Bedarf, bei einem Prozessgaskühler eine Regelvorrichtung für die Prozessgaskühlerklappen bereit zu stellen, womit die Prozessgaskühlerklappen trotz der unterschiedlichen thermischen Ausdehnung einwandfrei funktionieren.  There is therefore a need to provide a control device for the process gas cooler flaps in a process gas cooler, whereby the process gas cooler flaps function properly despite the different thermal expansion.
[0011] Der Erfindung liegt daher das Problem zugrunde, einen Prozessgaskühler mit regelbaren Prozessgaskühlerklappen zur Verfügung zu stellen, womit sie trotz thermischer Ausdehnung nicht verklemmen.

[0015] Damit die Prozessgaskühlerklappen (7) von außen gesteuert werden, ist ein Antriebskörper (13) vorgesehen, ein Teil des Antriebskörpers (13) wird innerhalb des Druckmantels im Auslassbereich (4) angebracht, und ein Teil des Antriebskörpers (13) wird nach außen geführt, so dass man den Antriebskörper (13) von außerhalb des Druckmantels steuern kann.  So that the process gas cooler flaps (7) are controlled from the outside, a drive body (13) is provided, a part of the drive body (13) is mounted within the pressure jacket in the outlet area (4), and a part of the drive body (13) is after guided outside, so that one can control the drive body (13) from outside the pressure jacket.
[0016] Mit Hilfe geeigneter Mittel, beispielhaft Hebel (10) und Verbindungsstange (11), sind die Klappenwellen (9) mit dem Antriebskörper (13) derart verbunden, dass sowohl die Gas- durchtrittsgeschwindigkeit als auch die Gasdurchtrittsmenge des Prozessgases (2) durch die Verbindungsöffnung (12), durch die Prozessgaskühlerklappe (7) von außen mit Hilfe vom Antriebskörper (13) steuerbar sind.  By means of suitable means, for example lever (10) and connecting rod (11), the flap shafts (9) with the drive body (13) are connected such that both the gas passage velocity and the gas passage amount of the process gas (2) the connection opening (12), are controlled by the process gas cooler flap (7) from the outside by means of the drive body (13).
[0017] Dabei kann der Antriebskörper ( 3) durch eine Antriebswelle, eine Schiebestange oder ein geeigneter Körper ausgebildet werden, so dass dieser Antriebskörper (13) die Klappenwellen (9) von außen steuert. Bei der Antriebswelle (13) wird deren Drehbewegung durch Hebel (10) und Verbindungsstangen (11) auf die Klappenwellen (9) übertragen. Mittels einer Schiebestange (13) kann die Klappenwellen (9) ebenfalls von außen geregelt werden, indem sie winkelbeweglich mit dem Hebel (10) und den Klappenwellen (9) verbunden sind.  In this case, the drive body (3) by a drive shaft, a push rod or a suitable body are formed, so that this drive body (13) controls the flap shafts (9) from the outside. In the drive shaft (13) whose rotation is transmitted by lever (10) and connecting rods (11) on the flap shafts (9). By means of a push rod (13), the flap shafts (9) can also be controlled from the outside by being angularly movably connected to the lever (10) and the flap shafts (9).
[0018] Vorzugsweise ist für jede Prozessgaskühlerklappe (7) eine Klappenwelle (9) vorgesehen. Dadurch kann jede Prozessgaskühlerklappe (7) in Bezug auf die Gasdurchtrittsge- schwindigkeit und -menge des Prozessgases (2) individuell eingestellt werden.  Preferably, a flap shaft (9) is provided for each process gas cooler flap (7). As a result, each process gas cooler flap (7) can be adjusted individually with respect to the gas passage speed and quantity of the process gas (2).
[0019] Als Alternative sind für den Durchgang des durch die Wärmeübertragungsrohre (5) strömenden Prozessgases mindestens zwei Verbindungsöffnungen (12) mit Prozessgaskühlerklappen (7) ausgebildet, und diese Prozessgaskühlerklappen (7) sind an einer gemeinsamen Klappenwelle (9) angebracht. Auch für den Durchgang des durch die Bypassrohre (6) strömenden Prozessgases sind mindestens zwei Verbindungsöffnungen (12) mit Prozessgaskühlerklappen (7) ausgebildet, und diese Prozessgaskühlerklappen (7) sind ebenfalls an einer gemeinsamen Klappenwelle (9) angebracht. Da das Prozessgas (2), das die Wärmeübertragungsrohre (5) oder Bypassrohre (6) durchströmt, jeweils annähend gleiche Temperatur aufweist, wird die auf diejenigen Prozessgaskühlerklappen (7) angebrachte gemeinsame Klappenwelle (9) thermisch gleichmäßig beaufschlagt.  As an alternative, at least two connection openings (12) with process gas cooler flaps (7) are formed for the passage of the process gas flowing through the heat transfer tubes (5), and these process gas cooler flaps (7) are attached to a common flap shaft (9). Also for the passage of the process gas flowing through the bypass tubes (6), at least two connection openings (12) with process gas cooler flaps (7) are formed, and these process gas cooler flaps (7) are also attached to a common flap shaft (9). Since the process gas (2), which flows through the heat transfer tubes (5) or bypass tubes (6), each has approximately the same temperature, which is applied to those process gas cooler flaps (7) common flap shaft (9) applied thermally evenly.
[0020] Die Klappenwellen (9) sind mittels der Hebel (10) und den Verbindungsstangen (11) direkt oder mit Hilfe anderer Mittel mit dem Antriebskörper (13) verbunden. Dies kann beispielsweise durch eine auf der Trennwand (14) angebrachte Zwischenwelle geschehen. Der Antriebskörper (13) treibt mittels der Hebel (10) und den Verbindungsstangen (11) eine innerhalb des Druckmantels befindliche Zwischenwelle an, von der aus die Drehbewegung mittels der Hebel (10) und den Verbindungsstangen (11) auf die Klappenwellen (9) übertragen wird. [0021] Da das das Bypassrohr (6) durchströmende Prozessgas nicht oder nur wenig gekühlt wird, weist das Prozessgas (2) am Austritt des Bypassrohrs (6) nahe der Verbindungsöffnung (12) bei der Prozessgaskühlerklappe (7) immerhin noch eine hohe Temperatur auf, weswegen die Prozessgaskühlerklappen (7) sowie die Klappenwellen (9) und die damit verbundenen Hebel (10) aus wärmebeständigen hochwertigen Materialien hergestellt werden müssen, um den korrosiven Angriff des Prozessgases (2) zu verhindern. The flap shafts (9) are connected by means of the lever (10) and the connecting rods (11) directly or by other means to the drive body (13). This can be done for example by an on the partition (14) mounted intermediate shaft. The drive body (13) drives by means of the lever (10) and the connecting rods (11) located within the pressure shell intermediate shaft from which transmit the rotational movement by means of the lever (10) and the connecting rods (11) on the flap shafts (9) becomes. Since the bypass pipe (6) flowing through the process gas is not or only slightly cooled, the process gas (2) at the outlet of the bypass pipe (6) near the connection opening (12) at the process gas cooler flap (7) after all, a high temperature why the Prozessgaskühlerklappen (7) and the flap shafts (9) and the associated lever (10) must be made of heat-resistant high-quality materials to prevent the corrosive attack of the process gas (2).
[0022] Eine wirtschaftliche Lösung hierzu ist, dass die den Durchgang des strömenden Prozessgases (2) in Bypassrohr (6) regelten Klappenwellen (9) und mit den verbundenen Hebel (10) eine Verkleidung (18) aufweisen, die den direkten Kontakt des Prozessgases (2) mit den Klappenwellen (9) und dem Hebel (10) in den Bereichen verhindert, in denen diese Bauteile eine für Korrosion ungünstige Temperatur aufweisen.  An economical solution to this is that the passage of the flowing process gas (2) in the bypass pipe (6) regulated flap shafts (9) and with the associated lever (10) have a covering (18), the direct contact of the process gas (2) with the flap shafts (9) and the lever (10) prevented in those areas in which these components have an unfavorable temperature for corrosion.
[0023] Im Bereich der Kontaktstellen der Verbindungsöffnung (12) zwischen den Bypass- rohren (6) und dem Auslassbereich (4) zur Trennwand (14) können sich ebenfalls für Korrosion ungünstige Bauteiltemperaturen im Betrieb einstellen. Diese Bereiche können ebenfalls eine Auskleidung (18) aufweisen, die den direkten Kontakt zum Prozessgas (2) verhindern. Eine solche Auskleidung (18) kann aus Beton bestehen.  In the area of the contact points of the connection opening (12) between the bypass tubes (6) and the outlet area (4) to the partition wall (14), unfavorable component temperatures can also be set during operation for corrosion. These areas can also have a lining (18) which prevents direct contact with the process gas (2). Such a lining (18) may consist of concrete.
[0024] Die Prozessgaskühlerklappen (7) sind derart an den Klappenwellen (9) angeordnet, dass im Betrieb stets mindestens eine der Prozessgaskühlerklappen (7) offen nicht ganz geschlossen ist ist  The process gas cooler flaps (7) are arranged on the flap shafts (9) such that in operation always at least one of the process gas cooler flaps (7) is not fully open
[0025] Damit immer mindestens eine Prozessgaskühlerklappe (7) in geöffneter, oder nicht ganz geschlossener Stellung steht, muss die Winkelstellung der Prozessgaskühlerklappen (7) zueinander entsprechend eingestellt werden, wobei die Hebel (10) der Prozessgaskühlerklappen (7) gleiche Längen haben. Eine vorteilhafte Ausgestaltungsmöglichkeit hierbei ist, dass die Hebel (10) unterschiedliche Längen aufweisen. Dadurch wird eine Über- oder Untersetzung des Drehwinkels des Antriebskörpers (13) auf die Prozessgaskühlerklappen (7) herbeigeführt. Insbesondere können die Drehwinkel der Prozessgaskühlerklappen (7) für das gekühlte und das weniger oder nicht gekühlte Prozessgas (2) unterschiedlich sein.  Thus, always at least one process gas cooler flap (7) is in the open, or not completely closed position, the angular position of the process gas cooler flaps (7) to each other must be adjusted accordingly, the levers (10) of the process gas cooler flaps (7) have the same lengths. An advantageous embodiment possibility here is that the levers (10) have different lengths. As a result, a transfer or reduction of the angle of rotation of the drive body (13) on the process gas cooler flaps (7) brought about. In particular, the angles of rotation of the process gas cooler flaps (7) can be different for the cooled and the less or not cooled process gas (2).
[0026] Die den Durchgang des strömenden Prozessgases (2) in Bypassrohr (6) regelnde Prozessgaskühlerklappe (7) ist mit einer Abkühlvorrichtung (16) versehen, die eine gleichmäßige Kühlung der Prozessgaskühlerklappe (7) durch das von außen durch eine Leitung (15) zugeleitete Kühlmedium gewährleistet.  The process gas cooler flap (7) regulating the passage of the flowing process gas (2) into the bypass tube (6) is provided with a cooling device (16) which ensures uniform cooling of the process gas cooler flap (7) by the outside through a line (15). supplied cooling medium ensured.
[0027] Um die Temperatur im Auslassbereich (4) zu überwachen, ist eine Temperaturüberwachungsvorrichtung im Auslassbereich (4) oder in der abführenden Leitung vorgesehen.  In order to monitor the temperature in the outlet area (4), a temperature monitoring device is provided in the outlet area (4) or in the discharge line.
[0028] Zum Betätigen des Antriebskörpers (13) ist ein Antrieb vorgesehen, wobei der Antrieb pneumatisch oder durch einen Motor angetrieben werden kann.  For actuating the drive body (13), a drive is provided, wherein the drive can be driven pneumatically or by a motor.
[0029] Nachfolgend wird die Erfindung anhand der Zeichnungen näher erläutert. [0030] Fig. 1 stellt einen Prozessgaskühler (1) mit hebelgesteuerten Prozessgaskühler- klappen (7) dar. The invention will be explained in more detail with reference to the drawings. FIG. 1 shows a process gas cooler (1) with lever-controlled process gas cooler flaps (7).

[0035] Fig. 1 zeigt ein Prozessgaskühler (1) für die Anwendung bei der Herstellung von Wasserstoff, Ammoniak, Alkenen oder Methanol. Das heiße Prozessgas (2) wird durch den Prozessgaskühler (1) entsprechend abgekühlt. Das Prozessgas (2) strömt mit mindestens 520°C in den Einlassbereich (3) des Prozessgaskühlers (1) hinein, wobei ein Teil des Prozessgases (2) durch die Wärmeübertragungsrohre (5), und der Rest durch die Bypassrohre (6) strömt. Das durch die Wärmeübertragungsrohre (5) abgekühlte und über die Bypassrohre (6) nicht oder wenig gekühlte Prozessgas (2) wird durch die Prozessgaskühlerklappen (7) geregelt in den Auslassbereich (4) fließen.  Fig. 1 shows a process gas cooler (1) for use in the production of hydrogen, ammonia, alkenes or methanol. The hot process gas (2) is cooled down accordingly by the process gas cooler (1). The process gas (2) flows into the inlet region (3) of the process gas cooler (1) with at least 520 ° C., whereby part of the process gas (2) flows through the heat transfer tubes (5) and the remainder flows through the bypass tubes (6).
