摘要:
PROBLEM TO BE SOLVED: To provide a filter cartridge which has a nonwoven melt blown fiber structure, wherein at least one filtration zone is comprised of relatively larger diameter support fibers integrally co-located with relatively smaller diameter filtration fibers, and has a wide range of "engineered" physical properties. SOLUTION: The support fibers have, on average, relatively larger diameters as compared to the filtration fibers which are integrally co-located therewith. Preferably, the filtration medium is disposed within at least one annular zone of a filtration element, for example, a disposable cylindrical filter cartridge having an axially elongate central hollow passageway 12 which is surrounded by the filtration media. A depth filter cartridge may thus be formed such that one or more additional filtration zones Z1, Z2, and Z3 are provided in annular relationship to one another. COPYRIGHT: (C)2008,JPO&INPIT

要解决的问题:提供一种具有非织造熔喷纤维结构的滤筒,其中至少一个过滤区域由相对较大直径的支撑纤维组成,其与相对较小直径的过滤纤维整体地定位,并且具有 广泛的“工程”物理特性。
解决方案:与与其整体地定位的过滤纤维相比,支撑纤维平均具有相对较大的直径。 优选地,过滤介质设置在过滤元件的至少一个环形区域中,例如,具有由过滤介质包围的轴向细长的中心中空通道12的一次性圆柱形过滤器滤芯。 因此,可以形成深度过滤器滤芯,使得一个或多个另外的过滤区域Z1,Z2和Z3彼此以环形关系设置。 版权所有(C)2008,JPO&INPIT
