Embodiment 1
[0059] Such as figure 1 , image 3 As shown, a hollow fiber membrane module includes a housing 1 with an inner diameter of 90 mm and a material made of UPVC (un-plasticized polyvinyl chloride) plastic, and a hollow fiber composed of 300 hollow fiber membrane filaments 2 arranged in the housing 1 Membrane bundle 3, the average pore diameter of the micropores of the hollow fiber membranes 2 for passing liquid is 0.1 μm, the outer diameter of the hollow fiber membranes is 1.35 mm, the material is polyvinylidene fluoride, and the two ends are casted and collected with epoxy resin In the upper end 4 and the lower end 5, and use polyurethane to carry out secondary casting to protect the root of the membrane. The overall shape of the upper end 4 and the lower end 5 is cup-shaped, and the diameter of the upper circle is 60 mm. Both the upper end head 4 and the lower end head 5 are provided with a water production collection chamber 9, and the two ends of the hollow fiber membrane fi...
Embodiment 2
[0067] Such as figure 2 , Figure 4 As shown, a hollow fiber membrane module includes a shell 1 with an inner diameter of 90 mm and a material made of UPVC plastic, a hollow fiber membrane bundle 3 composed of 180 hollow fiber membrane filaments 2 arranged in the shell 1, and a hollow fiber membrane The average pore diameter of the micropores of the filament 2 for passing liquid is 0.1 μm, the outer diameter of the hollow fiber membrane is 1.35 mm, the material is polyvinylidene fluoride, the upper end can swing freely, and each membrane filament is in a closed-pore state. Sealed with flexible epoxy resin, the lower end is poured with epoxy resin and collected in the lower end 5, and it is re-cast with polyurethane to protect the root of the membrane. The overall shape of the lower end 5 is cup-shaped, and the upper cross-section is a square with a side length of 50 mm. The hollow fiber membrane filament 2 is in a perforated state in the water production collection chamber ...
