Hollow fiber ultra-filtration film component with crisscross separating film

Abstract

The invention provides a hollow fiber ultra-filtration film component with a crisscross separating film, which comprises a pressure bearing outer shell; the center of the pressure bearing outer shell is provided with a central pipe; an ultra-filtration film is arranged between the inner wall of the pressure bearing outer shell and the central pipe; both ends of the pressure bearing outer shell are provided with sealant; and the component is characterized in that at least one crisscross separating film is arranged in the pressure bearing outer shell along the radial direction. The hollow fiber ultra-filtration film component with the crisscross separating film has the advantages of higher flowing speed of water flow and easy film component cleaning.

Description

technical field [0001] The invention relates to a hollow fiber ultrafiltration membrane module with a cross-shaped separator, and belongs to the technical field of ultrafiltration membrane modules. Background technique [0002] Such as figure 1 Shown is a schematic diagram of a traditional hollow fiber ultrafiltration membrane module, figure 2 Its A-A sectional view, the traditional hollow fiber ultrafiltration membrane module includes a pressure-bearing shell 1, the center of the pressure-bearing shell 1 is provided with a central conduit 2, and an ultrafiltration membrane 3 is arranged between the inner wall of the pressure-bearing shell 1 and the central conduit 2 , the two ends of the pressure-bearing shell 1 are provided with a sealant 4. After the sealant 4 is cast on both ends of the membrane module, the gap between the membrane filaments in the tube is extremely small. Such a structure will affect the ultrafiltration membrane. The speed of the water flow causes th...
