Abstract

The invention relates to a variable-diameter spinneret and a processing device of hollow fiber membrane tows and membrane component. The variable-diameter spinneret comprises a central circular pipe,a middle circular pipe, an outer cavity and a first drive mechanism and is characterized in that the central circular pipe, the middle circular pipe and the outer cavity are sequentially arranged in asleeved manner, the first drive mechanism drives the middle circular pipe to vertically move, and the bottoms of the central circular pipe, the middle circular pipe and the outer cavity are parallelto one another. The variable-diameter spinneret has the advantages that a membrane filament obtained by regulating the position of the middle circular pipe comprises large-diameter membrane filament heads at two ends and a small-diameter membrane filament middle section, and the porosity of the membrane filament middle section can be regulated by controlling the diameter ratio of the membrane filament heads to the membrane filament middle section during subsequent binding and membrane component assembling to achieve the optional filling density rule distribution of the membrane component.

Description

technical field [0001] The invention belongs to the technical field of hollow fiber membrane modules, in particular to a processing device of a variable diameter spinneret, a hollow fiber membrane tow and a membrane module. Background technique [0002] Membrane separation technology is widely used in seawater desalination, water treatment, biomedical and many other modern industrial technology fields. Membrane modules are key components in various membrane separation industries, and their processing technology and related equipment have important economic value. However, at present, the processing technology of modules using hollow fiber membranes mainly has defects such as inability to mechanize, low packing density and poor module performance consistency. With the wider application of membrane separation technology, higher requirements are placed on the automation of membrane module processing and module packing density.
