Definitions
- the invention is based on the object to promote the mixtures in chemical, especially catalytic reactions of reacting solids, liquids with the resulting vapors and gases during the reaction.
- reaction mixtures can not be circulated, which precludes a continuous reaction. It is therefore an object of the invention to circulate such reaction mixtures during the reaction and to use the good mixing in the delivery system for the acceleration of the reaction and thus reduction of the reaction plant. In the foreground is not the achievement of good efficiencies, but the use of the energy loss to heat the pumped liquid up to reaction temperature.
- the known pump systems are not suitable for promoting the resulting reaction mixtures of gases and vapors on the one hand and solids laden liquids on the other hand.
- Radial gear pumps react very critically to the gases and vapors produced during the reaction.
- the vapors forming during the reaction collect in the center of the impeller because of the low density and lead there to cavitation and to the demolition of the promotion.
- liquid ring vacuum pump One type of pump that creates large negative pressures in the inlet is the liquid ring vacuum pump. However, it is not suitable and intended for liquid and solid transport. This pump is capable of sucking gases and vapors, but not liquids and solids. It was therefore sought after a way to make this type of pump also for the promotion of liquids and solids and thus solve the inventive task.
- the object has been achieved in that the liquid ring vacuum pump combined with the properties of a radial pump.
- a new type of pump was created, which combines the promotion of fluids of the radial pump, the gas promotion of the liquid ring vacuum pump and also allows the promotion of solids by a special design of the channels.
- this study revealed the working discovery. It is the combination of both systems that allows the gases and vapors produced during the reaction to be separated from the liquid and to easily convey both states of matter.

- the delivery of solid and liquid substances on the circumference is done by a control system of the control discs, which transports these substances axially on the circumference and thus more and more solid and liquid materials are nachge redesignt.
- Impellers and control discs are arranged eccentrically. As a result, a liquid ring can form during the intake phase or during gas promotion, which lays on the impeller hub at different distances. Gas-filled spaces are formed which increase and decrease due to the eccentricity. In this operating state, the sludge reactor pump is well suited for the co-promotion of gases and vapors.
- the liquid / vapor mixture is sucked through a suction slot, which is located in the region of the largest distance of the liquid ring from the hub. Because of the different density, the reaction gas accumulates in the hub region and is ejected via a pressure slot, which is located in the region of the smallest distance of the liquid ring from the hub.
- the liquid is separated from the gas phase and discharged through openings in the form of slots or holes which are located on the housing outer diameter in the region of the highest case pressure or conveyed via a guide in the next stage.
- openings in the form of slots or holes which are located on the housing outer diameter in the region of the highest case pressure or conveyed via a guide in the next stage.
- the liquid guide vanes are arranged in front of the outlet openings. The promotion of liquid is possible only with moderate efficiency. The resulting power loss serves to supply energy to the pumped medium.
- a narrow axial gap between the housing and the impeller as in the liquid ring vacuum pump is not necessary because the liquid ring according to the invention does not have to be stabilized in a sealed chamber, but receives axial outlet openings, which are arranged in the region of the highest case pressure, if necessary with downstream guide.
- the design of the openings enables a comminution of the solids with simultaneous shearing action on the pumped medium.
- the liquid which flows through the pressure-side outlet openings is deflected in such a way that it is fed to the next stage or used as a bypass in single-stage machines. This results in a better mixing by a longer residence time of the medium and an additional energy input by friction for faster reaction.
- the ability of the liquid ring vacuum pump is obtained to generate a large intake negative pressure, to promote the gases and vapors as in the vacuum pump in the middle and the Radialrad aid nevertheless the liquid-solid mixture, the sludge, while reacting at high Temperature with through the pump to promote.
- the size of the executed in the embodiment of the invention guide profiles and holes thus simultaneously determine the delivery range of the pump to the solid-liquid mixture. Another advantage is the possibility of cleaning the system by reversing the direction of rotation of the pump.
- the shaft seal used are double-acting, non-directional mechanical seals which are filled with suitable fluid, e.g. Oil can be operated as a barrier medium between the pump side and the atmosphere side seal.
- the barrier liquid is circulated by means of auxiliary pumps with slight overpressure in relation to the pump-side seal.
- the pump bearing is arranged between the inner and outer seal so that the barrier liquid is used simultaneously for lubrication and cooling.
- heat exchangers are connected in the circuit.
- the higher pressure of the barrier fluid compared to the inner seal prevents the abrasive solid particles, such as metal, glass and stones in the sludge, from being kept away from the sealing gap, bearing and shaft.
- additional mixing can be achieved in a loop mixer placed in a bypass tube between the stages ( FIG. 9 ).

Abstract
Description
Der Erfindung liegt die Aufgabe zu Grunde, die Gemische bei chemischen, insbesondere katalytischen Reaktionen aus reagierenden Feststoffen, Flüssigkeiten mit den dabei entstehenden Dämpfen und Gasen während der Reaktion zu fördern.The invention is based on the object to promote the mixtures in chemical, especially catalytic reactions of reacting solids, liquids with the resulting vapors and gases during the reaction.
Bekannt sind aus der Reaktionstechnik Rührwerke in Behältern, die vorwiegend eine diskontinuierliche Reaktion ermöglichen. Die Inhalte werden erst nach Abschluss der Reaktion gefördert, wobei dann ein homogener flüssiger Zustand erreicht ist, der das Abpumpen mit den bekannten Pumpensystemen ermöglicht.Known from the reaction technology stirrers in containers, which allow mainly a discontinuous reaction. The contents are promoted only after completion of the reaction, in which case a homogeneous liquid state is reached, which allows the pumping with the known pump systems.
Während der Reaktion lassen sich die Reaktionsgemische nicht umwälzen, was eine kontinuierliche Reaktionsführung ausschließt. Es ist deshalb Ziel der Erfindung, solche Reaktionsgemische während der Reaktion umzuwälzen und die gute Vermischung in dem Fördersystem für die Beschleunigung der Reaktion und damit Verkleinerung der Reaktionsanlage zu nutzen. Im Fordergrund steht dabei nicht die Erzielung guter Wirkungsgrade, sondern die Nutzung der Verlustenergie zur Erwärmung der Förderflüssigkeit bis auf Reaktionstemperatur.During the reaction, the reaction mixtures can not be circulated, which precludes a continuous reaction. It is therefore an object of the invention to circulate such reaction mixtures during the reaction and to use the good mixing in the delivery system for the acceleration of the reaction and thus reduction of the reaction plant. In the foreground is not the achievement of good efficiencies, but the use of the energy loss to heat the pumped liquid up to reaction temperature.
Die bekannten Pumpensysteme sind zur Förderung der entstehenden Reaktionsgemische aus Gasen und Dämpfen einerseits und mit Feststoffen beladenen Flüssigkeiten anderseits nicht geeignet. Radialradpumpen reagieren auf die bei der Reaktion entstehenden Gase und Dämpfe sehr kritisch. Die sich bei der Reaktion bildenden Dämpfe sammeln sich wegen der geringen Dichte im Zentrum des Laufrades und führen dort zu Kavitation und zum Abriss der Förderung. Die damit verbundenen unzureichenden NPSH-Werte, d. h. die Entstehung unzulässiger Kavitation, führen zur Zerstörung der Pumpe.The known pump systems are not suitable for promoting the resulting reaction mixtures of gases and vapors on the one hand and solids laden liquids on the other hand. Radial gear pumps react very critically to the gases and vapors produced during the reaction. The vapors forming during the reaction collect in the center of the impeller because of the low density and lead there to cavitation and to the demolition of the promotion. The associated inadequate NPSH values, ie the formation of inadmissible cavitation, lead to the destruction of the pump.
Der notwendige Unterdruck zum Einsaugen der Reaktionsgemische ist bei den üblichen Pumpen mit Radialrädern nur in geringem Umfang möglich und außerhalb des Bereiches, den reagierende Gemische in Chemieanlagen haben. Seitenkanalpumpen können selbst ansaugen. Der mögliche Unterdruck ist aber nicht für die Reaktionsgemische ausreichend. Wegen der engen Spalte verstopfen die mitgeförderten Feststoffe die Kanäle. Die Lebensdauer bekannter Fördereinrichtungen ist gering, wenn es überhaupt zu einer Förderung kommt.The necessary negative pressure for sucking in the reaction mixtures is possible only to a small extent in the case of the customary pumps with radial wheels and outside the range which reacting mixtures have in chemical plants. Side channel pumps are self-priming. The possible negative pressure is not sufficient for the reaction mixtures. Because of the narrow gaps, the transported solids clog the channels. The life of known conveyors is low, if it comes to a promotion at all.
Eine Pumpenart, die im Einlauf große Unterdrücke erzeugt ist die Flüssigkeitsring-Vakuumpumpe. Sie ist jedoch nicht für den Flüssig- und Feststofftransport geeignet und vorgesehen. Diese Pumpe ist in der Lage, Gase und Dämpfe anzusaugen, nicht jedoch Flüssigkeiten und Feststoffe zu fördern. Es wurde deshalb nach einer Möglichkeit gesucht, diesen Pumpentyp auch für die Förderung von Flüssigkeiten und Feststoffen zu ertüchtigen und damit die erfinderische Aufgabe zu lösen.One type of pump that creates large negative pressures in the inlet is the liquid ring vacuum pump. However, it is not suitable and intended for liquid and solid transport. This pump is capable of sucking gases and vapors, but not liquids and solids. It was therefore sought after a way to make this type of pump also for the promotion of liquids and solids and thus solve the inventive task.
Dabei wurde überraschenderweise eine Lösung dafür gefunden. Erfindungsgemäß wurde die Aufgabe dadurch gelöst, daß die Flüssigkeitsring-Vakuumpumpe mit den Eigenschaften einer Radialpumpe kombiniert. Damit wurde ein neuer Pumpentyp geschaffen, der die Förderung von Flüssigkeiten der Radialpumpe, die Gasförderung der Flüssigkeitsring-Vakuumpumpe vereinigt und durch eine besondere Ausbildung der Kanäle zudem die Förderung der Feststoffe ermöglicht. Diese Untersuchung ergab überraschenderweise die funktionierende Entdeckung. Erst die Kombination beider Systeme ermöglicht die bei der Reaktion entstehenden Gase und Dämpfe von der Flüssigkeit zu trennen und beide Aggregatzustände problemlos zu fördern.It was surprisingly found a solution for this. According to the invention the object has been achieved in that the liquid ring vacuum pump combined with the properties of a radial pump. Thus, a new type of pump was created, which combines the promotion of fluids of the radial pump, the gas promotion of the liquid ring vacuum pump and also allows the promotion of solids by a special design of the channels. Surprisingly, this study revealed the working discovery. It is the combination of both systems that allows the gases and vapors produced during the reaction to be separated from the liquid and to easily convey both states of matter.
Das Trennen der Gase und Dämpfe geschieht dabei auf dem Prinzip der Flüssigkeitsring-Vakuumpumpe, die durch die Zentrifugalkraft des Flügellaufrades diese nach innen abscheidet und fördert. Die Förderung der festen und flüssigen Stoffe am Umfang geschieht durch ein Leitsystem der Steuerscheiben, die diese Stoffe am Umfang axial transportiert und damit immer neue feste und flüssige Stoffe nachgefördert werden.The separation of the gases and vapors is done on the principle of the liquid ring vacuum pump, which separates and promotes this inward by the centrifugal force of the Flügelaufaufrades. The delivery of solid and liquid substances on the circumference is done by a control system of the control discs, which transports these substances axially on the circumference and thus more and more solid and liquid materials are nachgefördert.
Beiderseits der Laufräder sind Steuerscheiben angeordnet, die den Pumpenraum begrenzen. Laufräder und Steuerscheiben sind exzentrisch angeordnet. Dadurch kann sich während der Ansaugphase oder bei Gasmitförderung ein Flüssigkeitsring ausbilden, der sich mit unterschiedlichem Abstand an die Laufradnabe legt. Es bilden sich gasgefüllte Räume, die sich wegen der Exzentrizität vergrößern und verkleinern. In diesem Betriebszustand ist die Schlammreaktorpumpe gut zur Mitförderung von Gasen und Dämpfen geeignet.On both sides of the wheels control discs are arranged, which limit the pump room. Impellers and control discs are arranged eccentrically. As a result, a liquid ring can form during the intake phase or during gas promotion, which lays on the impeller hub at different distances. Gas-filled spaces are formed which increase and decrease due to the eccentricity. In this operating state, the sludge reactor pump is well suited for the co-promotion of gases and vapors.
Das Flüssigkeits-/Dampfgemisch wird durch einen Saugschlitz, der sich im Bereich des größten Abstandes des Flüssigkeitsringes von der Nabe befindet, angesaugt. Wegen der unterschiedlichen Dichte sammelt sich das Reaktionsgas im Nabenbereich und wird über einen Druckschlitz, der im Bereich des kleinsten Abstandes des Flüssigkeitsringes von der Nabe befindet, ausgestoßen.The liquid / vapor mixture is sucked through a suction slot, which is located in the region of the largest distance of the liquid ring from the hub. Because of the different density, the reaction gas accumulates in the hub region and is ejected via a pressure slot, which is located in the region of the smallest distance of the liquid ring from the hub.
Über die Radialkomponente des Laufrades wird die Flüssigkeit von der Gasphase getrennt und über Öffnungen in Form von Schlitzen oder Bohrungen, die am Gehäuseaußendurchmesser liegen im Bereich des höchsten Gehäusedruckes ausgeleitet bzw. über eine Leiteinrichtung in die nächste Stufe gefördert. Zur Umlenkung der Flüssigkeit sind vor den Austrittsöffnungen Leitschaufeln angeordnet. Die Förderung von Flüssigkeit ist nur mit mäßigem Wirkungsgrad möglich. Die dadurch entstehende Verlustleistung dient der Energiezufuhr an das Fördermedium.About the radial component of the impeller, the liquid is separated from the gas phase and discharged through openings in the form of slots or holes which are located on the housing outer diameter in the region of the highest case pressure or conveyed via a guide in the next stage. For deflecting the liquid guide vanes are arranged in front of the outlet openings. The promotion of liquid is possible only with moderate efficiency. The resulting power loss serves to supply energy to the pumped medium.
Ein enger Axialspalt zwischen Gehäuse und Laufrad wie bei der Flüssigkeitsring-vakuumpumpe ist nicht erforderlich, weil der Flüssigkeitsring erfindungsgemäß nicht in einer abgeschlossenen Kammer stabilisiert werden muss, sondern axiale Austrittsöffnungen erhält, die im Bereich des höchsten Gehäusedrucks angeordnet werden, bei Bedarf mit nachgeschalteten Leiteinrichtung. Die Gestaltung der Öffnungen ermöglicht ein Zerkleinern der Feststoffe bei gleichzeitiger Scherwirkung auf das Fördermedium.A narrow axial gap between the housing and the impeller as in the liquid ring vacuum pump is not necessary because the liquid ring according to the invention does not have to be stabilized in a sealed chamber, but receives axial outlet openings, which are arranged in the region of the highest case pressure, if necessary with downstream guide. The design of the openings enables a comminution of the solids with simultaneous shearing action on the pumped medium.
In der Leiteinrichtung wird die Flüssigkeit, welche durch die druckseitigen Austrittsöffnungen strömt in der Weise umgelenkt, dass sie der nächsten Stufe zugeführt bzw. bei einstufigen Maschinen als Bypaß genutzt wird. Damit ergibt sich eine bessere Vermischung durch längere Verweilzeit des Mediums und ein zusätzlicher Energieeintrag durch Reibung zum schnelleren Reaktionsablauf.In the guide, the liquid which flows through the pressure-side outlet openings is deflected in such a way that it is fed to the next stage or used as a bypass in single-stage machines. This results in a better mixing by a longer residence time of the medium and an additional energy input by friction for faster reaction.
Dadurch wird es ermöglicht, dass der Flüssigkeitsring oder auch Feststoff-Flüssigkeitsring ständig ausgetauscht wird und durch die neu einströmenden Gemische aus Feststoffen und Flüssigkeit in die nächste Stufe bzw. in die Förderleitung gedrückt wird. Bei dieser Betriebsweise kommt es zu einer intensiven Vermischung zwischen Flüssigkeitsring und nachströmendem Fördermedium.This makes it possible that the liquid ring or solid-liquid ring is constantly replaced and is pressed by the newly flowing mixtures of solids and liquid in the next stage or in the delivery line. In this mode of operation, there is an intensive mixing between the liquid ring and nachströmendem medium.
Dabei wird die Fähigkeit der Flüssigkeitsring-Vakuumpumpe erhalten, einen großen Ansaugunterdruck zu erzeugen, die Gase und Dämpfe wie in der Vakuumpumpe in der Mitte zu fördern und durch das Radialradprinzip trotzdem das Flüssigkeits-Feststoff-Gemisch, den Schlamm, gleichzeitig im reagierenden Zustand bei hoher Temperatur mit durch die Pumpe zu fördern.The ability of the liquid ring vacuum pump is obtained to generate a large intake negative pressure, to promote the gases and vapors as in the vacuum pump in the middle and the Radialradprinzip nevertheless the liquid-solid mixture, the sludge, while reacting at high Temperature with through the pump to promote.
Die Größe der in der erfindungsgemäßen Ausführung ausgeführten Leitprofile und Bohrungen bestimmen damit gleichzeitig den Förderbereich der Pumpe an dem Feststoff-Flüssigkeits-Gemisch. Ein weiterer Vorteil liegt in der Möglichkeit einer Reinigung der Anlage durch Drehrichtungsumkehr der Pumpe. Als Wellendichtung kommen doppeltwirkende, drehrichtungsunabhängige Gleitringdichtungen zum Einsatz, die mit geeigneter Flüssigkeit, z.B. Öl als Sperrmedium zwischen pumpenseitiger und atmosphärenseitiger Dichtung betrieben werden.The size of the executed in the embodiment of the invention guide profiles and holes thus simultaneously determine the delivery range of the pump to the solid-liquid mixture. Another advantage is the possibility of cleaning the system by reversing the direction of rotation of the pump. The shaft seal used are double-acting, non-directional mechanical seals which are filled with suitable fluid, e.g. Oil can be operated as a barrier medium between the pump side and the atmosphere side seal.
Die Sperrflüssigkeit wird mit leichtem Überdruck gegenüber der pumpenseitigen Dichtung über Hilfspumpen umgewälzt. Erfindungsgemäß ist zwischen innerer und äußerer Dichtung das Pumpenlager so angeordnet, dass die Sperrflüssigkeit gleichzeitig zur Schmierung und Kühlung genutzt wird. Um die Temperatur an der Gleitringdichtung und am Pumpenlager im zulässigen Bereich zu halten sind in den Kreislauf Wärmetauscher geschaltet.The barrier liquid is circulated by means of auxiliary pumps with slight overpressure in relation to the pump-side seal. According to the pump bearing is arranged between the inner and outer seal so that the barrier liquid is used simultaneously for lubrication and cooling. In order to keep the temperature at the mechanical seal and at the pump bearing within the permissible range, heat exchangers are connected in the circuit.
Der höhere Druck der Sperrflüssigkeit gegenüber der inneren Dichtung verhindert, dass die im Schlamm eingetragenen abrasiven Feststoffteile, wie z.B. Metall, Glas und Steine von Dichtspalt, Lager und Welle ferngehalten werden. Über die beschriebene Anwendung hinaus kann in einem Schleifenmischer, der in einem Bypassrohr zwischen den Stufen angeordnet wird, zusätzliche Vermischung erreicht werden (
Die nachfolgenden Figuren erläutern die Erfindung.
Die Austrittsöffnung zur Entleerung der Pumpe ist mit 5 bezeichnet. Über die Bohrungen 8 ist der Flüssigkeitsring mit der nächsten Stufe mit dem Gemischeintritt für die nächste Stufe 6 verbunden. Dadurch gelangt der mit der Zentrifugalkraft am Außenumfang gebildete Ring aus Flüssigkeit und Feststoffen über die Zwischenwand zwischen den beiden Stufen von außen nach innen in den innen liegenden Gemischeintritt 6.

In der Leitkammer befinden sich die Leiteinrichtungen 9, die die von außen nach innen zwischen den Stufen geleiteten Flüssigkeits- und Feststoffe strömungstechnisch in die nächste Stufe so leiten, daß keine Verstopfungen oder strömungstechnische Blockaden auftreten. Dieses wird in der
