The inlet of the hollow fiber column 2 is connected to the other end of the inlet pipe 1 through a TC clamp 9, and the outlet of the hollow fiber column 2 is connected to one end of the return pipe 4 through a TC clamp 9. The TC clamp 9 can realize the quick connection and disassembly of the hollow fiber column 2 with the inlet pipe 1 and the return pipe 4. At the same time, the TC clamp 9 is made of PP material and supports irradiation sterilization. The second pump head 5 is connected to the other end of the return pipe 4 through a pagoda connector 8. Both the first pump head 3 and the second pump head 5 are centrifugal pump heads, which can be quickly connected to the flexible silicone tube through the pagoda connector 8.

Air filter 15 is connected to air tube 14 through pagoda connector 8. Pagoda connector 8 can be quickly connected to flexible silicone tubing. Air filter 15 filters air impurities in air tube 14 and introduces gas through air tube 14 to expel substances remaining in hollow fiber column 2, which are then discharged through exhaust tube 13.
