Abstract
本发明的实施例提供了螺旋缠绕反渗透元件中的进给间隔件网的连续层的替代物,并且利用支撑元件的入口端和出口端的进给间隔件网的分立区域和用于在元件卷绕过程期间在构成元件的每个膜页片的尾端处在这些区域之间进行桥接的加强桥特征来替代这种网。加强桥特征防止膜页片的内层在卷绕期间向内偏转,有利于使用已知的膜卷绕技术将粘合剂通过渗透物载体适当地密封到相邻的薄膜上。
Description
技术领域
本发明涉及用于螺旋缠绕元件(诸如在反渗透系统中使用的那些螺旋缠绕元件)的膜的领域。
背景技术
螺旋缠绕元件在本领域中是已知的,并且传统上由被密封在多孔网上的涂覆的多孔半透膜片组成,该多孔网允许分离开的流体纵向流动到穿孔中心管以便进行收集。常规单元还包括织造或挤出的多孔间隔件网,该间隔件网允许在元件内进行轴向或纵向流动。这种网对于构造来说是典型的,但就以下方面而言具有显著缺点:生物淤积的可能性、流动的阻力、结垢、以及构造的复杂性。
Barger等人和Bradford等人已经描述了螺旋缠绕膜的改进,其中,替代于织造或挤出的多孔网,使用来自膜片的活性涂覆表面的沉积岛或突起提供了支撑以在元件内轴向地保持恒定的流体流动间隔。在适当设计的情况下,这些特征可以减少进给通道中的流动限制,并且减少由生物膜生长、结垢、或颗粒捕获导致的元件污染的机会,并且简化了元件制造。
当多孔网用于在螺旋缠绕过滤元件中提供进给间隔时,网密度通常足够高,以在元件被卷绕时在元件的整个区域上提供均匀的支撑,这允许在卷绕的同时将均匀的压力施加到所用的粘合剂上,以穿过渗透物载体渗透到膜页片边缘中,从而形成渗透物流过其中的密封包壳。然而,对于不使用分离开的隔离件网的元件设计,由于不均匀或不期望的胶水压实,缺乏来自分离开的网的支撑会导致组装方面的问题,特别是在胶水线附近的、与来自渗透载体的膜的相反的进给空间区域中。
发明内容
本发明提供了用于分离开流体部件的螺旋缠绕元件的构造的改进,该元件具有显著降低的流体流动阻力、增加的通道流动面积、由于印刷或沉积材料而被遮挡的较小的膜表面面积以及增加的制造容易度。具体而言,螺旋缠绕元件使用包括固体纵向间隔件的印刷或沉积的间隔件以在膜片的尾端附近为胶水渗透和密封提供支撑来构造。改进的构造方法可以不允许在螺旋缠绕元件的内部使用进给间隔件。
本发明的实施例提供了一种用于在具有渗透物载体的层压组合物中使用的膜片,其中,该膜片具有被配置成提供选择性流体分离的活性表面和与该活性表面相反的非活性表面,并且其中,该膜片具有进给间隔元件,这些进给间隔元件布置在该活性表面上、在该活性表面的两个相反边缘中的每一个边缘附近的进给间隔件区域中,并且其中,该膜片具有加强桥特征,该加强桥特征布置在该活性表面、该非活性表面、或它们的组合上,在该膜片的边缘附近而不是该两个相反边缘的区域中。典型地,这种膜片是矩形的,其长度大于宽度,并且进给间隔元件沿着长度或长度的一半布置,使得当折叠时,进给间隔元件沿着折叠的膜片的长度延伸。在这种构造中,加强桥特征将沿着片材的宽度布置在一个端部附近,使得当折叠时,该加强桥特征在两个端部会合的端部处。这种片材通常与渗透物载体匹配,在边缘周围施加有粘合剂,然后围绕收集管卷绕以形成螺旋缠绕元件。
在一些实施例中,该加强桥特征布置在该活性表面上。在一些实施例中,该加强桥特征布置在该非活性表面上。在一些实施例中,该膜片的活性表面的在这些进给间隔区域之间的中心区域没有进给间隔元件。在一些实施例中,该桥加强部件被附着到该膜片上,并背离该膜片突出至少与该进给间隔元件的高度相等的距离。在一些实施例中,该桥加强特征在这些进给间隔区域之间在该膜上是连续的。在一些实施例中,该桥加强特征包括多个元件,该多个元件一起在这些进给间隔区域之间跨越该膜。
本发明的实施例提供了一种用于在螺旋缠绕膜元件中使用的层压组合物,该层压组合物包括:(a)渗透物载体;(b)膜片,该膜片具有被配置成提供选择性流体分离的活性表面和与该活性表面相反的非活性表面,并且其中,该膜片具有进给间隔元件,这些进给间隔元件布置在该活性表面上、在该活性表面的两个相反边缘中的每一个边缘附近的区域中,并且其中,该膜片具有加强桥特征,该加强桥特征布置在该活性表面、该非活性表面、或它们的组合上,在该膜片的边缘附近而不是该两个相反边缘的区域中,其中,该膜片具有与该渗透物载体的宽度基本上相等的宽度,并且具有与该渗透物载体的长度的大约两倍基本上相等的长度;(c)其中,该膜片被布置成使得该非活性表面与该渗透物载体接触。这种实施例通常具有围绕三个边缘(具有加强桥特征的端部加上两个长边缘)施加的粘合剂,然后围绕收集管卷绕以形成螺旋缠绕元件。
在一些实施例中,该加强桥特征布置在该活性表面上。在一些实施例中,该加强桥特征布置在该非活性表面上。在一些实施例中,该膜片的活性表面的中心区域没有进给间隔元件。在一些实施例中,该桥加强部件被附着到该膜片上,并背离该膜片突出至少与该进给间隔元件的高度相等的距离。在一些实施例中,该桥加强特征在这些进给间隔区域之间在该膜上是连续的。在一些实施例中,该桥加强特征包括多个元件,该多个元件一起在这些进给间隔区域之间跨越该膜。在一些实施例中,该膜片的特征在于具有宽度和长度,并且该膜片沿着围绕膜片的长度中间的折叠线折叠,使得活性表面彼此面对;并且该膜片布置在该渗透物载体上,使得该加强桥特征在该膜片的远离该渗透物载体的部分上。
本发明的实施例提供了一种生产螺旋缠绕元件的方法,该方法包括:(a)提供具有长度和宽度的渗透物载体片材;(b)提供收集管;(c)提供膜片,该膜片具有被配置成提供选择性流体分离的活性表面和与该活性表面相反的非活性表面,并且其中,该膜片具有进给间隔元件,这些进给间隔元件布置在该活性表面上、在该活性表面的两个相反边缘中的每一个边缘附近的区域中,并且其中,该膜片具有加强桥特征,该加强桥特征布置在该活性表面、该非活性表面、或它们的组合上,在该膜片的边缘附近而不是该两个相反边缘的区域中,其中,该膜片具有与该渗透物载体的宽度基本上相等的宽度,并且具有与该渗透物载体的长度的大约两倍基本上相等的长度;(d)沿着沿该膜片的宽度延伸的折叠线折叠该膜片,使得该膜片的活性表面在折叠的片材内部;(e)将折叠的膜片放置成使得该非活性表面与该渗透物载体接触,从而形成元件页片,该元件页片具有在该膜片的折叠部附近的第一端部和与该折叠部相反并平行的第二端部,其中,两个相反的边缘折叠并连接该第一端部和该第二端部,并且具有在该渗透物载体附近的第一部分和通过该第一部分而与该渗透物载体分离开的第二部分;(f)将粘合剂施加到该膜片、该渗透物载体、或它们的组合上,使得该粘合剂在该第一边缘附近和该两个边缘附近在该膜页片上延伸;(g)围绕该收集管缠绕该元件页片,其中,该元件页片的第一端部靠近该收集管,从而形成螺旋缠绕元件。膜片尺寸“基本上等于”渗透物载体尺寸意味着相对应的尺寸足够接近等于允许方便的组装和卷绕而没有不期望的浪费。例如,如果所得到的元件的端部按照惯例被修剪,则宽度不需要完全相等,但是它们需要足够接近以相等,使得被修剪的元件被合适地密封。例如,长度可能由于需要微小的差异来适应围绕管的片材的螺旋缠绕而不完全相等,但是长度应该足够接近相等,使得所得到的螺旋缠绕元件没有过多长度的多余的膜片或渗透物载体。
一些实施例进一步包括固化该粘合剂,然后移除对应于该元件页片的两个边缘的螺旋缠绕元件的一部分,其中该元件页片在这种移除之后,仍然具有沿着该第二端部和该两个边缘围绕该渗透物载体完全密封该膜片的粘合剂。
在一些实施例中,步骤(e)包括放置该膜片,使得该加强桥特征与该膜片的第二部分在一起。

具体实施方式
以下专利和申请有助于理解本发明,并通过引用结合于此:PCT/US2014/018813;PCT/US2018/016318;PCT/US2017/052116;PCT/US2017/062424;PCT/US2017/062425;PCT/US2018/027367;PCT/US2018/028453。
在元件组装或卷绕期间,通常使用粘合剂来将渗透物载体的内端部粘附到中心管上并且同时将渗透物载体沿膜片的三个外边缘粘合到该膜片上,这用于防止来自进给流或未处理的/废弃流的流体进入该渗透物载体,除非其穿过该膜。粘合剂密封膜片和渗透物载体两者的边缘,从而迫使任何从进给到渗透区的流体流动通过膜。粘合剂密封同时限定了渗透物包壳的三个边缘,并允许该包壳中的流动被引导朝向中心收集管。中心收集管在形状上通常是圆柱形的,但是该“管”可以具有与该组件和希望的操作特性相容的任何形状。
该粘合剂典型地是在螺旋缠绕元件被卷起之前施加的,并且一旦粘合剂被固化,就在每个端部处以固定长度在垂直于圆柱形元件的轴线的平面上修剪掉过量的膜、渗透物载体、和粘合剂。为了有效操作,需要在螺旋缠绕元件的相邻活性页片之间提供间隔,以允许将流体的入口流和出口流分离开。在元件制造期间,这个间隔件提供刚性以维持开放的进给/废弃通道,同时迫使粘合剂渗透穿过渗透物载体以密封渗透物包壳。在一些元件中,在相邻的页片之间布置连续的材料片材,以提供进给间隔件。这种连续进给间隔件会限制流体流动并受到污染的影响。
在一些元件中,间隔特征例如通过沉积或印刷仅放置在膜的选定区域中。例如,间隔特征可以仅沿着元件的进给和未处理/废弃边缘沉积,以提供所需的间隔。这种间隔特征还支撑膜以促进以上提及的粘合剂渗透—间隔特征布置在与粘合剂沿着膜页片的入口和出口边缘沉积的位置相反的区域中,使得间隔件支撑膜足以允许膜有助于期望的胶渗透到渗透物载体中。然而,沿边缘的间隔特征并未在页片的远端处提供支撑。
本发明的示例性实施例提供了在页片的远端处提供附加支撑的加强桥特征。间隔特征的附加区域也可以用在元件中,但是加强桥允许不连续的间隔特征段之间的空白区域。加强桥特征被配置成为膜片赋予比边缘间隔特征更大的刚度,因为当膜片被卷成螺旋缠绕元件时,边缘间隔特征以螺旋方式彼此叠置,从而为每个附加绕组提供支撑,而在远端处的加强桥特征除了边缘间隔特征或条带之间的任何材料之外,在其下方没有支撑。因此,加强桥特征应该提供足够的刚度,以提供支撑,而在卷绕过程期间没有由粘合剂引起的显著的向内偏转。加强桥特征以与加强桥特征的厚度和构成加强桥特征的材料的抗拉强度成比例地将抗弯强度添加到膜页片。由于典型薄膜的薄度,加强桥特征中的少量附加材料可以显著地增加薄膜/桥系统的抗弯强度。
在本发明的一些实施例中,边缘间隔特征之间的区域可以被留为空的,或者可以包含印刷或沉积在这个区域中的薄膜上的附加特征。由于在卷绕过程期间边缘间隔特征支撑元该件,这些附加的中心特征可以是任何厚度的,上至边缘间隔特征的厚度。如果存在的话,中心特征可以包括以比边缘间隔特征更稀疏或不同的图案沉积或印刷在膜表面上的特征。它们可以包括具有与边缘间距特征不同的几何形状的网。可以选择这些中心特征的能力以促进在流体流中的局部涡流或湍流,或者使螺旋缠绕元件内的污染的可能性最小化。
本发明的实施例采用与加强桥特征相结合的不连续的进给间隔元件,该加强桥特征使得在元件卷绕过程期间能够在不连续区域中进行适当的粘合剂密封。不连续进给间隔元件可以包括两个分立的区域,一个布置在膜页片的入口端处,且一个布置在膜页片的出口端处,它们之间具有间隙。其他实施例可以包括进给间隔元件的任何构型,其中间隔件的高度在大约1″或更大的长度尺度上是不连续的,诸如由3个不同的区域组成(每个边缘处有一个区域,并且沿着它们之间的页片中心向下有一个区域)的进给间隔件、或者以不同厚度的区域制造的挤出网。在任何上述情况下,都添加了加强桥特征,以允许使用标准的元件卷绕技术来在膜页片的远端或尾端处实现适当的粘合剂密封。
在图1中示出的本发明的示例性实施例中,单个均匀的加强桥特征6被沉积在膜页片的活性表面的内半部2上,使得当页片被折叠并且螺旋缠绕元件被组装时,在卷成元件时,加强桥特征6相对于中心收集管布置在折叠页片2的内半部的远端处。加强桥特征6的高度和形状被配置成在这个区域中加强膜页片,使得该加强桥特征支撑膜页片的远端,以减少在卷绕过程期间由粘合剂引起的偏转。加强桥特征可以在膜的整个宽度上延伸,如所示出的,或者可以仅在具有边缘间隔特征的两个区域之间延伸,例如在具有边缘间隔特征的区域一直延伸到膜的端部的情况下。可以基于粘合剂、膜、渗透物载体、卷绕程序和力以及期望的粘合剂渗透的性质来确定期望的硬度。远端区域的加强可以帮助确保用于形成层压夹层的远侧胶线被迫渗透被夹层的渗透物载体4并粘附到相对的膜片3上,而不允许最内的膜页片2朝螺旋缠绕元件的中心向内偏转。
在图2中示出的本发明的另一示例性实施例中,单个连续的加强条带6被沉积到膜页片7的内侧或非活性支撑表面上,使得当膜页片被折叠并且螺旋缠绕元件被组装时,在被卷成元件时,加强桥特征6相对于中心收集管1被布置在膜页片的远端处、并且在折叠的页片2的内半部上。特征的高度和形状被配置成在卷绕期间为膜的这个区段提供附加的刚度,以确保用于形成层压夹层的胶被迫渗透夹层的渗透物载体4并粘附到相对的膜页片3上,而不允许内膜片2朝向螺旋缠绕元件的中心向内成弓形。
在一个示例性实施例中,将12″宽的薄膜复合膜片切割成80″的长度。边缘支撑进给间隔元件包括被定向为与流体入口流到出口流的方向成45°且彼此成90°的交替杆的图案。在这个示例性实施例中,进给间隔元件约为0.25″长、约为0.018宽、约为0.015″高,并且使用UV固化喷墨打印机沉积到膜表面上、在膜片材的活性侧上的半部上,沿着膜片的任一纵向边缘对齐成2″宽的条带,并且在中心留下8″的膜片未印刷。其他进给间隔元件设计和过程可以是合适的,更多的示例参见通过引用结合于此的PCT申请。附加地,在使用相同的UV固化喷墨工艺沉积的12″宽、1.5″长和0.015″高的膜片的印刷半部的远端处印刷实心加强桥特征。其他尺寸也是合适的;例如,从片材的三分之一到全宽的任何宽度、从0.1″到5.0″或从1″到2.5″的任何长度;以及从进给间隔元件的高度的0.5至2.0倍的高度。在边缘支撑间隔件和加强桥特征已经建立之后,折叠页片,使得膜的活性表面彼此面对,其中,印刷特征位于折叠的页片的内部。将折叠的页片放置到50″×12″长的渗透物载体上,同时页片的未印刷的半部被定向成使得其与渗透物载体接触。渗透物载体沿着12″边缘中的一个边缘附接到直径为0.67″的12″长的中心管。膜页片被放置在渗透物载体上,使得页片中的折叠部与中心管的附接件间隔约5″。粘合剂被应用在连续卷边中,从在渗透物载体到中心管的附接件处、距膜页片的边缘约一英寸的点开始、并且继续沿一条长边缘、围绕与该折叠部相反的端部、并且沿另一长边在距该边缘1″距离处返回。在粘合剂沉积之后,该页片围绕中心管卷绕以形成具有外直径为约1.8″的螺旋缠绕元件。粘合剂干燥之后,螺旋缠绕元件的端部从中心管的每个边缘中修剪掉大约1″,在12″长的中心管上留下约10″长×约1.8″直径的螺旋缠绕元件结构。在元件的每个边缘上,保留了大约1″的边缘间隔特征,这允许进给流进入和废弃流排出。这种描述描述了一个示例性实施例。然而,这些印刷图案可以应用于不同直径和长度的螺旋缠绕元件。
加强桥特征可以包括各种几何形状,并且可以使用不同的形状,只要它们覆盖足够的区域,使得它们将支撑膜页片的远端或尾端处的粘合线在卷绕时将覆盖的区域。当在卷绕期间被完全压缩时,粘合线的宽度通常在1″到2.5″的长度范围内,并且将覆盖膜页片的端部的整个宽度。图3至图5展示了几个示例,这些示例包括:包括实心条带6、几组与中心收集管1平行地延伸的平行线8或线段9、或者其它复杂形状,只要它们在元件卷起期间总体上防止其上印刷或沉积特征的区域朝向中心管1偏转。为了在构造中使用更少的材料,在其整个尺寸上不是实心的形状可以是优选的。
加强桥特征可以由与分离开的流体和渗透物载体相容的任何数量的材料构成,包括但不限于塑料、热塑性塑料、反应性聚合物、蜡、或树脂。
加强桥特征可以通过多种技术来沉积。传统的印刷技术(诸如胶版印刷、凹版印刷、和丝网印刷)可以是合适的,尽管这些沉积技术可能呈现出厚度和几何形状限制。较厚的特征可以通过微喷射、喷墨印刷、熔融沉积、或通过使用粘合剂的应用来沉积,这可以包括片的辊转移或单独特征的拾放。
在卷绕之前,边缘间隔特征被放置到膜页片的一侧或两侧中的活性侧上,以便在卷绕螺旋缠绕元件期间保持进给间隔。这些边缘间隔特征可以被留在适当的位置,或者在卷绕螺旋缠绕元件之后的修剪期间或之后部分地去除。边缘间隔特征5允许在元件沿元件边缘卷绕期间压缩粘合剂,以确保粘合剂完全渗入渗透物载体4并且粘合到渗透物载体的两侧上的膜片2上,同时在这些边缘处保持与进给间隔特征的高度大致相等的高度分离开。
以这种方式放置的边缘间隔特征可以是分立的条带、或不连续的部段(例如,多个点、多条线等)。如果使用分立的条带,这些条带必须或者在元件的后续修剪期间被完全地移除、或者由多孔材料构成从而在修剪之后条带的某个部分被留适当位置的情况下允许流体流过它们。多孔边缘间隔特征可以由多孔材料构成,诸如织造或非织造织物或挤压或织造网,其延伸到元件的内部中不超过胶线多余约半英寸,以便允许进给流体流过边缘特征。
已经结合各个示例性实施例描述了本发明。应当理解,以上描述仅用于说明本发明的原理的应用,本发明的范围将由参照说明书的权利要求来确定。本发明的其他变型和修改对于本领域的技术人员来说将是显而易见的。
