| 摘要 |
A membrane separation device is provided with membrane modules (20) comprising multiple membrane elements (21), a frame body (11) accommodating the membrane modules (20) stacked in multiple stages, a stopper (14) for closing an end portion of the frame body to prevent the membrane modules (20) accommodated in the frame (11) from being released, and elastic members (15) which, arranged in a state of elastic deformation in the vertical direction in the frame (11) with the end portion of the frame (11) being closed, suppress vertical vibration of the membrane modules (20) accommodated in the frame (11), whereby making it possible to avoid vibration of the membrane modules inside the frame body even if the volume of the membrane modules accommodated in the frame body varies. |
