Abstract

本发明涉及薄膜技术领域，尤其是一种高性能水处理用PVDF膜。其包括膜体、格栅、滤网和固定网，膜体的上表面上设有格槽，格栅设置在膜体的顶部，滤网设置在格栅的顶部，固定网包裹在膜体、格栅和滤网组合体的外部。在膜体的上表面开设格槽，并在格槽内嵌装尺寸一致的格栅，同时在格栅的上方覆盖一层滤网，通过固定网包裹成一体。使用时，污水先经过滤网，拦截掉颗粒较大的杂质，防止堵塞膜体；然后进入格栅，均匀分布到各个栅孔内，避免局部淤积，提高过滤的均匀度；最后在膜体的各个隔离区间内同步过滤渗透，大大提高了膜体的利用率，提高了过滤效果。

Description

高性能水处理用PVDF膜
技术领域
本发明涉及薄膜技术领域，尤其是一种高性能水处理用PVDF膜。
背景技术
PVDF膜即聚偏二氟乙烯膜，是蛋白质印迹法中常用的一种固相支持物。PVDF膜是疏水性的，膜孔径有大有小，随着膜孔径的不断减小，膜对低分子量的蛋白结合就越牢固。大于20000的蛋白选用0.45um的膜，小于20000的蛋白选用0.2um的膜。PVDF膜具有较高的机械强度，是印迹法中的理想固相支持物材料，广泛应用于水处理、户外建筑及电池领域，尤其用于污水、海水淡化等的前处理，清除大分子、细菌、泥沙等杂质。现有的PVDF膜都为单一结构，过滤除杂效果差。
发明内容
为了克服现有的PVDF膜结构单一，过滤除杂效果差的不足，本发明提供了一种高性能水处理用PVDF膜。
本发明解决其技术问题所采用的技术方案是：一种高性能水处理用PVDF膜，包括膜体、格栅、滤网和固定网，膜体的上表面上设有格槽，格栅设置在膜体的顶部，滤网设置在格栅的顶部，固定网包裹在膜体、格栅和滤网组合体的外部。
根据本发明的另一个实施例，进一步包括格槽的尺寸与格栅一致。
根据本发明的另一个实施例，进一步包括格栅的底部嵌在格槽内，与膜体连接成一体。
根据本发明的另一个实施例，进一步包括滤网的孔径较格栅的孔径小，覆盖在格栅的上方。
本发明的有益效果是，在膜体的上表面开设格槽，并在格槽内嵌装尺寸一致的格栅，同时在格栅的上方覆盖一层滤网，通过固定网包裹成一体。使用时，污水先经过滤网，拦截掉颗粒较大的杂质，防止堵塞膜体；然后进入格栅，均匀分布到各个栅孔内，避免局部淤积，提高过滤的均匀度；最后在膜体的各个隔离区间内同步过滤渗透，大大提高了膜体的利用率，提高了过滤效果。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图。
图中1. 膜体，2. 格栅，3. 滤网，4. 固定网，5. 格槽。
具体实施方式
如图1是本发明的结构示意图，一种高性能水处理用PVDF膜，包括膜体1、格栅2、滤网3和固定网4，膜体1的上表面上设有格槽5，格栅2设置在膜体1的顶部，滤网3设置在格栅2的顶部，固定网4包裹在膜体1、格栅2和滤网3组合体的外部。格槽5的尺寸与格栅2一致。格栅2的底部嵌在格槽5内，与膜体1连接成一体。滤网3的孔径较格栅2的孔径小，覆盖在格栅2的上方。
在膜体1的上表面开设格槽5，并在格槽5内嵌装尺寸一致的格栅2，同时在格栅2的上方覆盖一层滤网3，通过固定网4包裹成一体。使用时，污水先经过滤网3，拦截掉颗粒较大的杂质，防止堵塞膜体1；然后进入格栅2，均匀分布到各个栅孔内，避免局部淤积，提高过滤的均匀度；最后在膜体1的各个隔离区间内同步过滤渗透，大大提高了膜体1的利用率，提高了过滤效果。
