Abstract

本实用新型涉及过滤膜，公开了一种烧结管式超滤膜，包括烧结管体和均匀涂布于烧结管体表面的纳米膜。本实用新型具有处理粘度大固形物含量高的污水效率高的优点。

Description

烧结管式超滤膜
技术领域
本实用新型涉及过滤膜，尤其涉及一种烧结管式超滤膜。
背景技术
高分子分离膜(polymeric membrane for separation)，是由聚合物或高分子复合材料制得的具有分离流体混合物功能的薄膜。膜分离过程就是用分离膜作间隔层，在压力差、浓度差或电位差的推动力下，借流体混合物中各组分透过膜的速率不同，使之在膜的两侧分别富集，以达到分离、精制、浓缩及回收利用的目的。传统的分离膜主要是平板膜，而这种平板膜用于粘度大固形物含量高的工业污水的过滤效率较差。
发明内容
为克服平板膜用于粘度大固形物含量高的工业污水的过滤效率较差的缺陷，本实用新型的目的在于提供一种对粘度大固形物含量高的污水处理效率高的烧结管式超滤膜。
本实用新型的目的是通过以下技术措施实现的，一种烧结管式超滤膜，包括烧结管体和均匀涂布于烧结管体表面的PVDF(聚偏氟乙烯)纳米膜。
作为一种优选方式，所述烧结管体为多孔的圆管或椭圆管。其材质可为PE、PA(聚酰胺)或PI(聚酰亚胺)。
作为一种优选方式，所述纳米膜为孔隙50nm～100nm、孔隙率40％～80％的PVDF纳米膜。也可以是聚砜纳米膜、聚丙烯纳米膜或聚四佛乙烯纳米膜。
作为一种优选方式，所述纳米膜涂布于烧结管体内表面或外表面或内外表面。
本实用新型以聚偏氟乙烯为原料，形成一种具有微孔性的薄膜，并将此薄膜覆合在多孔的烧结管体表面，成为新型过滤材料，聚偏氟乙烯薄膜的膜孔径小，分布均匀，孔隙率大，在保持水流通的同时，可以过滤包括细菌在内的各种固形物。
本实用新型表面面积大，过滤效率高，同时污水在其中边流动边过滤，不易因阻塞而影响其过滤效率，在使用时可将多条烧结管式超滤膜并联使用，从而在能有效地提高对污水的过滤效率。
附图说明
图1是本实用新型实施例1的横切面视图；
图2是本实用新型实施例2的横切面视图。
具体实施方式
下面结合实施例并对照附图对本实用新型作进一步详细说明。
实施例1
如图1，一种烧结管式超滤膜，包括多孔的PE圆形烧结管体1和均匀涂布于烧结管体1内表面的PVDF纳米膜2。PVDF纳米膜2的孔隙为50nm～100nm，其孔隙率为40％～80％。
实施例2
如图2，一种烧结管式超滤膜，包括多孔的PE椭圆形烧结管体1和均匀涂布于烧结管体内表面和外表面的PVDF纳米膜2和3。PVDF纳米膜2和3的孔隙为50nm～100nm，其孔隙率为40％～80％。
以上是对本实用新型烧结管式超滤膜进行了阐述，用于帮助理解本实用新型，但本实用新型的实施方式并不受上述实施例的限制，任何未背离本实用新型原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本实用新型的保护范围之内。
