Title:
APPARATUS HAVING TEMPERATURE CONTROL STRUCTURE FOR HEAT TREATMENT OF INNER SURFACE OF BRAID FOR REINFORCING HOLLOW FIBER MEMBRANE FOR WATER TREATMENT
Document Type and Number:
WIPO Patent Application WO/2018/030674
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for heat treatment of an inner surface of a braid for reinforcing a hollow fiber membrane for water treatment and, more particularly, to an apparatus comprising a temperature control structure for heat treatment of an inner surface of a braid for reinforcing a hollow fiber membrane for water treatment, wherein the temperature control structure allows a fiber tissue accounting for the inner surface of the braid to be dense, an inner diameter of the braid to expand, roundness of inner and outer diameters to be improved, and an internal pressure resistance to be increased, whereby the hollow fiber reinforcement membrane can be improved in physical properties, filtration reliability, water permeability, life span, economic efficiency, and heat efficiency, and can prevent an operator from safety accidents such as burns upon operation such as a replacement work of layered yarns.
