Abstract
Die Erfindung betrifft Formkörper für den Einsatz in Schüttschichten oder strukturierten Packungen mit verbesserten Wärmeübertragungseigenschaften, insbesondere einer verbesserten effektiven Wärmeleitfähigkeit der Schüttschicht. Aufgabe der Erfindung ist die Verbesserung der effektiven Wärmeleitfähigkeit von Schüttschichten aus Formkörpern. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Materialien zu Formkörpern verarbeitet werden, die mindestens drei definierte Begrenzugsflächen aufweisen, wobei die Begrenzungsflächen der Formkörper in einer Schüttschicht aus mehreren Formkörpern miteinander Kontaktflächen ausbilden können. Der Vorteil der Erfindung besteht darin, daß in Schüttschichten aus Formkörpern der erfindungsgemäßen Art der Anteil der Festkörperwärmeleitung durch die Kontaktflächenberührung der Partikel an der Gesamtwärmeübertragungsbilanz erhöht wird. Auch bei Formkörpern aus schlecht wärmeleitendem Material wird dadurch die Wärmeübertragung in der Schüttschicht wesentlich verbessert.The invention relates to moldings for use in packed beds or structured packings with improved heat transfer properties, in particular an improved effective thermal conductivity of the packed bed. The object of the invention is to improve the effective thermal conductivity of bulk layers of moldings. According to the invention the object is achieved in that the materials are processed into moldings having at least three defined Begrenzugsflächen, wherein the boundary surfaces of the moldings can form contact surfaces with each other in a packed layer of a plurality of moldings. The advantage of the invention is that is increased in bulk layers of moldings of the type according to the invention, the proportion of the solid heat transfer through the contact surface contact of the particles in the total heat transfer balance. Even with moldings made of poorly heat-conductive material, the heat transfer in the bulk layer is significantly improved.
Description
Die Erfindung betrifft eine Schüttschicht mit Sorptionsmittel enthaltenden Formkörpern aus Vollmaterial mit verbesserten Wärmeübertragungseigenschaften.The The invention relates to a packed bed with sorbent-containing moldings of solid material with improved heat transfer properties.
Die betreffenden Schüttschichten werden beispielsweise in Apparaten zum Stoff- und/oder Wärmeaustausch eingesetzt. Typische Anwendungsfälle sind Destillations- Rektifikations- und Sorptionskolonnen bzw. -behälter. Dabei sind die Formkörper als Festbett in einem Behälter angeordnet und im Falle einer nicht durchströmten Schüttung sind die Formkörper von einer fluiden Phase umgeben bzw. werden bei einer durchströmten Schüttung von der fluiden Phase umströmt. Bei der Form der Anordnung der Formkörper kann es sich um eine Zufallsschüttung oder um sogenannte strukturierte Packungen handeln.The relevant bulk layers For example, in apparatuses for mass and / or heat exchange used. Typical applications are distillation, rectification and sorption columns or containers. there are the moldings as a fixed bed in a container arranged and in the case of a non-flow-through bed are the moldings of surrounded by a fluid phase or be in a flow-through bed of flows around the fluid phase. In the form of the arrangement of the shaped body may be a random pad or to act as so-called structured packs.
Je nach Material der Formkörper können diese an Stoffumwandlungs- bzw. Stoffaustauschprozessen, katalytischen Prozessen oder Stofftrennprozessen beteiligt sein. Neben dem Stofftransport spielt für viele Anwendungsgebiete der Wärmetransport in der Schüttung eine große Rolle. Die Wärmeleiteigenschaften einer Schüttung aus Formkörpern sind von besonderer Wichtigkeit, wenn Wärme durch indirekte Wärmeübertragung über einen Wärmeübertrager aus dem Festbett ausgekoppelt bzw. in das Festbett eingebracht werden soll.ever according to the material of the moldings can these at Stoffumwandlungs- or mass transfer processes, catalytic Be involved in processes or mass separation processes. In addition to the substance transport plays for many applications of heat transport in the bed a big Role. The heat conduction properties a bed from shaped bodies are of particular importance when heat is transferred by indirect heat transfer over a Heat exchanger off decoupled from the fixed bed or introduced into the fixed bed should.
Ganz besonders trifft das für den Einsatz von Formkörpern in Sorptionsbehältern von Adsorptionskälteanlagen zu. Die Formkörper bestehen dabei aus Sorptionsmitteln, welche sich bei der Adsorption aus der fluiden Phase erwärmen, wobei ein Teil der Wärme über Wärmeübertragungseinbauten ausgekoppelt werden soll, und welche zur Desorption der adsorbierten Stoffe erwärmt werden müssen.All this is especially true for the use of moldings in sorption tanks of adsorption refrigeration systems to. The moldings consist of sorbents, which are produced during adsorption from the fluid phase, with some of the heat via heat transfer internals is to be decoupled, and which for the desorption of the adsorbed Heated fabrics Need to become.
Als Materialen für Formkörper werden Zeolith in verschiedensten Typen, Aktivkohle, Kieselgele u. a. in Kombination mit Bindemitteln, Füllstoffen oder porenbildenden Stoffen verwendet. Im Stand der Technik werden die Materialien zu Formkörpern verarbeitet. Bekannte Ausführungsformen sind beispielsweise Kugeln verschiedenster Durchmesser oder Stränge mit kreisförmigen oder anderen, abgerundeten Querschnitten sowie geometrisch nicht definierte kristalline Partikel bzw. Bruchstüche.When Materials for moldings are zeolite in various types, activated carbon, silica gels u. a. in combination with binders, fillers or pore-forming Used substances. In the prior art, the materials become too moldings processed. Known embodiments For example, balls of different diameters or strands with circular or other, rounded cross sections as well as not geometrically defined crystalline particles or fracture particles.

Der Nachteil dieses Standes der Technik ist die schlechte effektive Wärmeleitfähigkeit von Schüttungen derartiger Formkörper.Of the Disadvantage of this prior art is the bad effective thermal conductivity of fillings such shaped body.
Aufgabe der Erfindung ist die Verbesserung der effektiven Wärmeleitfähigkeit von Schüttschichten aus Formkörpern.task The invention is the improvement of the effective thermal conductivity of loose layers from shaped bodies.
Erfindungsgemäß wird die Aufgabe durch eine Schüttschicht mit Sorptionsmittel enthaltenden Formkörpern aus Vollmaterial gelöst, wobei die Formkörper aus einem Strang mit fünfeckiger Querschnittsfläche und einem Verhältnis von Außenkreisdurchmesser der Querschnittsfläche zu Stranglänge von 0,1 bis 5 ausgebildet sind und wobei mehrere eine Schüttschicht bildende Formkörper an ihren Begrenzungsflächen gemeinsame Kontaktflächen und Kontaktlinien ausbilden. Der Vorteil der Erfindung besteht darin, dass in den erfindungsgemäßen Schüttschichten aus Formkörpern der Anteil der Festkörperwärmeleitung durch die Kontaktflächenberührung der Partikel an der Gesamtwärmeübertragungsbilanz erhöht wird. Auch bei Formkörpern aus schlecht wärmeleitendem Material wird dadurch die Wärmeübertragung in der Schüttschicht wesentlich verbessert.According to the invention, this object is achieved a bulk layer containing sorbent-containing moldings made of solid material, wherein the moldings are formed from a strand having a pentagonal cross-sectional area and a ratio of outer circle diameter of the cross-sectional area to strand length of 0.1 to 5 and wherein a plurality of a bulk layer forming moldings at their boundary surfaces common contact surfaces and lines of contact form. The advantage of the invention is that in the packed beds of shaped bodies according to the invention, the proportion of solid-body heat conduction through contact surface contact of the particles with the total heat transfer balance is increased. Even with moldings made of poorly heat-conductive material, the heat transfer in the bulk layer is significantly improved.
