Description
BEZEICHNUNG: Mechanischer-Emülsions- und Schaum-BrecherDESCRIPTION: Mechanical emulsion and foam breaker
Die Erfindung bezieht sich auf ein Koaleszenzelement zur Abscheidung einer flüssigen, diskontinuierlichen Nebenphase aus einer flüssigen Hauptphase, das sich zusammensetzt aus einem Fußteil, einem Kopfteil, einem dazwischen angeordneten gelochten Kernrohr und mit auf das Kernrohr aufgewickelten Faserpackungen, die von einer Stützbandage, einem Schaumbrecher und einem äußeren Außenmantel umgeben und mit Kopfteil und Fußteil dichtend verklebt sind.The invention relates to a coalescence element for separating a liquid, discontinuous secondary phase from a liquid main phase, which consists of a base part, a head part, a perforated core tube arranged between them and with fiber packings wound on the core tube, which are surrounded by a support bandage, a foam breaker and an outer outer jacket and are sealed to the head part and base part.
Bei der Strömung eines Phasengemisches durch eine Faserschicht benetzen die Flüssigkeitspartikel der diskontinuierlichen Phase die Faseroberflächen und bilden mit zunehmendem Fließweg einen mit der Hauptströmung zur Austrittsseite wandernden Flüssigkeitsfilm, der sich am Austritt aus der Faserschichten periodisch als großer, quasi spontan abscheidender Tropfen ablöst. Ein dem Fasermaterial aufliegendes, schaumbrechendes Material verhindert dabei mögliche Schaumbildung, die aus der Zusammensetzung der diskontinuierlichen Phase oder einem eventuellen Lufteintrag resultieren kann, und die Ablösung der koalisierten Tropfen störend beeinträchtigt.When a phase mixture flows through a fiber layer, the liquid particles of the discontinuous phase wet the fiber surfaces and, as the flow path increases, form a liquid film that migrates with the main flow to the exit side and periodically separates as a large, quasi-spontaneously separating droplet at the exit from the fiber layer. A foam-breaking material lying on top of the fiber material prevents possible foam formation, which can result from the composition of the discontinuous phase or a possible ingress of air, and which disrupts the detachment of the coalesced droplets.
Die bekannten Coalisierelemente dieser Art werden dadurch hergestellt, daß die Faserpackungen auf ein Kernrohr aufgebracht und vorher oder gleichzeitig mit einem Bindemittel, vorzugsweise Phenolharz, getränkt werden, damit die Fasern nach der Aushärtung fixiert sind. Um zu verhindern, daß das Phasengemisch unter Umgehung der Faserschichten die Faserpackungen im Bereich ihrer Enden umfließt, werden die beiden axialen Endbereiche der Faserschichten mit einem Klebstoff oder einer aushärtenden Formmasse vergossen und gleichzeitig mit den Anschlagflächen des Aufhahmeteils und des Kopfteils verklebt.The known coalescing elements of this type are manufactured by applying the fiber packings to a core tube and impregnating them beforehand or at the same time with a binding agent, preferably phenolic resin, so that the fibers are fixed after hardening. In order to prevent the phase mixture from flowing around the fiber packings in the area of their ends, bypassing the fiber layers, the two axial end areas of the fiber layers are cast with an adhesive or a hardening molding compound and simultaneously glued to the stop surfaces of the receiving part and the head part.
Die bekannten Coalisierelemente haben den Nachteil, daß sie in vielen industriellen Prozessen nur beschränkt einsetzbar sind, weil insbesondere die verwendeten Faserpackungen nicht für Flüssigkeiten geeignet sind, dessen kontinuierliche Nebenphase auch noch stark verschmutzt ist und dadurch Wirkungsgrad und Wirtschaftlichkeit negativ beeinträchtig. Auch der Effekt der Schaumbildung aufgrund von Luftzufuhr bei entsprechender chemischer ZusammensetzungThe known coalescing elements have the disadvantage that they can only be used to a limited extent in many industrial processes, because the fiber packings used are not suitable for liquids, the continuous secondary phase of which is also heavily contaminated, and therefore has a negative impact on efficiency and profitability. The effect of foam formation due to the supply of air with the corresponding chemical composition

wird ungenügend berücksichtigt, so daß bei gegebenem Wirkungsgrad dieser durch schaumbildende Effekte wieder vermindert wird.is not sufficiently taken into account, so that at a given efficiency this is reduced again by foam-forming effects.
Der Erfindung liegt die Aufgabe zugrunde, Phasentrennelemente mit einer Coalisierschicht aus Fasern, insbesondere Glasfasern, Metallfasern, Naturfasern oder monofilen Kunststoff-Fasern und einem speziellen schaumbrechenden Material dahingehend zu verbessern, daß die Faserpackungen nicht nur gegen Verschmutzung und Lufteinflüsse weitgehend unempfindlich sind, sondern zusätzliche Schwerkräfte entwickeln, die zur Trennung der von der diskontinuierlichen Phase umgebenen Schmutzpartikel führen - unabhängig von der chemischen Zusammensetzung der diskontinuierlichen Phase.The invention is based on the object of improving phase separation elements with a coalescing layer made of fibers, in particular glass fibers, metal fibers, natural fibers or monofilament plastic fibers and a special foam-breaking material in such a way that the fiber packings are not only largely insensitive to contamination and air influences, but also develop additional gravitational forces that lead to the separation of the dirt particles surrounded by the discontinuous phase - regardless of the chemical composition of the discontinuous phase.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die in den Faserpackungen und dem Schaumbrechermaterial verarbeiteten Fasern in Material, Struktur und Dichteaufbau so ausgewählt sind, daß bei einer großen Porenweite gleichzeitig ein hohes Benetzungsverhalten (Koaleszenz) der Fasern und somit eine Abscheidung der diskontinuierlichen Phase bis auf die Löslichkeitsgrenze erreicht wird.This object is achieved according to the invention in that the fibers processed in the fiber packings and the foam breaker material are selected in terms of material, structure and density structure in such a way that, with a large pore size, a high wetting behavior (coalescence) of the fibers and thus a separation of the discontinuous phase up to the solubility limit is achieved.
