Zusammenfassung: | The present invention relates to a separation membrane unit for an immersion-type membrane separation device, which comprises: a separation membrane frame; a suction pipe installed on the separation membrane frame to have a flow path inside and a plurality of tap holes communicating with the flow path in a lower part; a plurality of hollow fiber membrane modules mounted on the separation membrane frame, formed by connecting the hollow fiber membranes between headers having the flow path inside, and having outlet holes on both ends thereof to communicate with the flow path in the header; a header connector having one end inserted into and joined to the outlet hole of the header and the other end bent upward to extend toward the tap hole of the suction pipe; a suction pipe connector having one end inserted into the tap hole of the suction pipe and the other end extended toward the header connector; a middle connector interposed between the header connector and the suction pipe connector, joined to be moved while sliding vertically, and composed of an upper body and a lower body divided by a flange in the middle, wherein O-rings are inserted into ring grooves formed on the upper body and the lower body to keep watertight and 1-2 mm of clearance is formed between inner wall surfaces of the header connector and the suction pipe connector in order to make the middle connector move in a horizontal direction such that the middle connector can interlock vertical flow force to horizontal flow force delivered through the hollow fiber membrane module and the suction pipe and continuously absorb the force; and a diffuser installed on the lower part of the separation membrane frame to generate aeration to produce a water current, thereby removing foreign materials attached to the hollow fiber membrane in the hollow fiber membrane module. The present invention has a structure which can compensate for bending or twist although a header connector or a suction pipe connector is excessively bent or twisted.
