The invention provides an immersion type
hollow fiber membrane element. The immersion type
hollow fiber membrane element comprises an upper end cover, a lower end cover, a membrane shell, a plurality of
hollow fiber membrane filaments, an upper end sealing fixing layer and a lower end sealing fixing layer. The invention also discloses a hollow
fiber membrane module device adopting the immersion type hollow
fiber membrane element. The hollow
fiber membrane module device comprises a box body, a concentrated water collector, a quick-mounting
fastener, a
water production sealing cover, a hoisting piece, a sealing piece, a partition plate, a plurality of immersion type hollow fiber membrane elements, a water inlet sealing cover and a gas
distributor. The invention further discloses a hollow fiber membrane module device
system adopting the immersion type hollow fiber membrane module device. The hollow fiber membrane module device
system comprises a plurality of immersion type hollow fiber membrane module devices, a water inlet / blow-off pipeline, a gas inlet pipeline, a concentrated water pipeline and a
water production pipeline. The device is simple in structure, high in
pollution resistance and cleaning effect, high in interchangeability, long in service life, low in
investment cost, convenient to transport, convenient to install and maintain, and capable of saving the occupied space of the
system and the
engineering cost.
