Title (DE) MEHRSCHICHTIGE SEPARATIONSEINHEITEN
(EN) MULTI-LAYER SEPARATION UNITS
(FR) UNITES DE SEPARATION A COUCHES MULTIPLES
Abstract:
(DE) Um unterschiedliche Separations- oder Filtrationsprobleme zu lösen, sind im Stand der Technik Separationselemente mit unterschiedlichstem Aufbau der Separationseinheiten bekannt. Darunter befinden sich auch Separationselemente mit mehrschichtigen Separationseinheiten. Die erfindungsgemäße Lösung zeichnet sich dadurch aus, daß die erfindungsgemäßen Separationseinheiten (17) in einem kontinuierlichen Prozeß hergestellt werden können und durch einen Schicht für Schicht Aufbau, der auch nicht bahnförmige Separationsmittel (24) enthält, optimal an spezifische Separationsprobleme anpaßbar sind.
(EN) In order to solve different separation or filtration problems, the prior art discloses separation elements whose separation units have very different constructions, including separation elements with multi-layer separation units. The solution according to the invention is characterized in that the separation units (17) according to the invention can be produced in a continuous process and can be adapted optimally to specific separation problems by a layer-by-layer construction which also contains separating means (24) which are not in strip form.
(FR) Pour résoudre différents problèmes de séparation ou de filtration, dans l'état de la technique, on fait appel à des éléments de séparation aux structures les plus diverses des unités de séparation. Les éléments de séparation à unités de séparation à couches multiples en font partie. Selon la présente invention, la solution préconisée se caractérise en ce que les unités de séparation (17) obtenues selon l'invention peuvent être produites dans le cadre d'un processus continu et peuvent être adaptées optimalement aux problèmes de séparation spécifiques, par une structure couche par couche qui contient également des éléments de séparation (24) ne se présentant pas sous forme de bandes.
