Embodiment

[0010] Such as figure 2 Shown is a schematic structural diagram of a hollow fiber ultrafiltration membrane module with a wavy separator. The hollow fiber ultrafiltration membrane module with wavy partitions is composed of a pressure-bearing shell 1 , a hollow conduit 2 , ultrafiltration membrane filaments and a wavy partition 4 . The center of the pressure-bearing shell 1 is provided with a hollow conduit 2 along the axial direction, and at least two corrugated partition plates 4 are arranged radially between the hollow conduit 2 and the pressure-contained shell 1. Filter silk.

[0011] During use, enter water from the water inlet on the pressure-bearing shell 1 and the hollow conduit 2, wash the ultrafiltration membrane wire, and discharge water from the water outlet on the pressure-bearing housing 1. The separation effect between the rooms is good, the flow rate of the water outlet is increased, and it is easier to backwash and positively wash.

Abstract

The invention provides a hollow fiber ultra-filtration membrane assembly having a wave division plate, which comprises a pressure-bearing shell. A hollow conduit is axially arranged on the center of the pressure-bearing shell, wherein at least two wave division plates are radially arranged between the hollow conduit and the pressure-bearing shell while an ultra-filtration membrane filament is arranged between the two wave division plates. The invention has the advantages that the water outflow speed is increased so both the back and front washings are easier.

Description

technical field [0001] The invention relates to a hollow fiber ultrafiltration membrane module with a wavy partition plate, belonging to the technical field of ultrafiltration membrane modules. Background technique [0002] Such as figure 1 As shown, it is a schematic structural diagram of a traditional hollow fiber ultrafiltration membrane module. The hollow fiber ultrafiltration membrane module includes a pressure-bearing shell 1, and the center of the pressure-bearing shell 1 is provided with a hollow conduit 2 along the axial direction. The hollow conduit 2 is connected to the pressure-bearing At least two flat partitions 3 are arranged radially between the housings 1 , and ultrafiltration membrane filaments are arranged between the flat partitions 3 . The disadvantage of this kind of hollow fiber ultrafiltration membrane module is that the separation effect of the ultrafiltration membrane filaments is not good, they are easy to squeeze together and cannot be rinsed cle...
