Embodiment Construction

[0025] Further illustrate the present invention below in conjunction with accompanying drawing.

[0026] see figure 1 , figure 2 The membrane filter sheet of the present invention comprises a filter membrane 1, a membrane diversion support layer 2 and a framework 3 that is connected with the diversion support layer to fix the filter membrane and the diversion support layer, and the filter membrane is positioned at both sides of the diversion support layer. One or more diversion openings 4 are symmetrically opened on the frame in the length direction of the filter sheet, and the filter membrane is sealed and connected with the frame.

[0027] see image 3 , Figure 4 , the flat membrane filter element of the present invention includes a membrane filter sheet and a combined outer frame 6 . The inner side of the outer frame has a diversion groove 8 for the filtered fluid, the longitudinal outer side has a groove 9 for fixing the membrane filter element, and the lateral outer...

Abstract

A compact plate type membrane filter and its membrane filter element and equipment are disclosed. Said membrane filter is composed of filtering membrane, guiding-supporting layer of membrane, and skeleton with one or more symmetrical guide openings and connected with filtering membrane in sealing mode.

Description

technical field [0001] The invention relates to a membrane filter with microfiltration or ultrafiltration membrane as the filter medium, and a membrane filter element and device with such a membrane filter, in particular to a flat polymer microfiltration or ultrafiltration The filter membrane is a compact membrane filter sheet as a filter medium, and a membrane filter element and device with such a membrane filter sheet. Background technique [0002] The microfiltration membrane or ultrafiltration membrane made of polymer materials is a very versatile membrane filtration medium. The traditional assembly methods include plate and frame type, folded type, roll type and tube type. The first three types are more The porous flat membrane is used as the filter medium, and the fourth type uses porous tubular, capillary, and hollow fiber membranes as the filter medium. As early as the 1980s and 1990s, these products have been available for sale. Various fields have played a positiv...
