Manufacturing equipment and method of PTFE hollow fiber membrane with asymmetric structure

The invention discloses equipment and a method for manufacturing a PTFE (Polytetrafluoroethylene) hollow fiber membrane with an asymmetric structure. A corona machine I is arranged between a PTFE hollow fiber membrane supporting layer unwinding device and a wrapping device and is used for carrying out corona treatment on a PTFE hollow fiber membrane supporting layer; the corona machine II is arranged corresponding to the wrapping device and is used for carrying out corona treatment on the PTFE hollow fiber membrane wrapping tape and carrying out secondary corona treatment on the PTFE hollow fiber membrane supporting layer; in addition, the third corona machine is arranged between the wrapping device and the sintering furnace and used for conducting corona treatment on the PTFE hollow fiber membrane before sintering. The PTFE hollow fiber membrane is subjected to corona treatment, so that the adhesion between the fiber membrane supporting layer and the flat sheet membrane (wrapping tape) in the PTFE is improve
