Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a hollow fiber membrane module pouring device and a method thereof. Background technique [0002] Membrane separation technology is a high-tech widely used in liquid or gas separation, purification or concentration. Due to its large specific surface area, high packing density, simple process, no support layer, and low production cost, hollow fiber membranes have become an important branch of membrane separation technology and are widely used in chemical, environmental protection, and pharmaceutical fields. The hollow fiber membrane usually uses the membrane module as the permeation unit, and the membrane module is composed of a large number of hollow fiber membrane filaments solidified in the membrane shell through an adhesive to form a relatively closed separation environment. The pouring quality of the membrane module has a great influence on the performance and ef...
