Abstract: In a humidifying membrane module, a humidifying membrane having plural hollow fiber membranes bundled together is housed in a humidifying membrane chassis having a cylindrical outer periphery, and the humidifying membrane chassis is housed in an assembly chassis having a cylindrical inner periphery. The assembly chassis has an inlet port for taking air that is made to flow into hollow parts of the humidifying membrane, an outlet port for discharging the air, an inlet port for taking an off-gas that is made to flow in gaps in the humidifying membrane, and an outlet port for discharging the off-gas. The air and the off-gas flow in flow paths formed by utilizing the humidifying membrane chassis and the assembly chassis, but are not mixed with each other at positions other than the humidifying membrane owing to annular sealing members provided between the humidifying chassis and the assembly chassis.

Abstract: Case 10 is characterized by providing a pair of mutually facing surfaces, and a pair of side surfaces which join that pair of surfaces, opening 11 which is the entrance is formed on one of the surfaces 10a of the opposing pair of surfaces, while the opening 12 which is the exit is formed on the other surface 10b, and spaces S1 and S2 are provided between one surface 10a and the hollow fiber membrane stack 20, and between the other surface 10b and the hollow fiber membrane stack 20 in the entire domain in the direction from one side extreme of case 10 to the other side extreme, with the exception of the part where sealing and fixing devices 31 and 32 are provided, moreover, no space is configured between the pair of side surfaces and the hollow fiber membrane stack 20.

Abstract: The present invention relates to a filter device for removing impurities contained in liquid. A filter housing 18 is provided with a container for accommodating a filter bag 2 therein, a deposit recovery tank 3 for recovering a deposit and a floating material recovery tank 4 for recovering a floating material. Thus, it is possible to prevent any deterioration of filtration performance caused by filtered and separated impurities, and to achieve both of filtration and specific gravity difference separation by a single device.

Abstract: The present invention relates to a filter device for removing impurities in a liquid. A filter bag 2 and a bag filter bucket 3 are disposed so that their opening portions are oriented downward. An annular gap between an outer peripheral face of the bag filter bucket 3 and an inner peripheral face of a main body 41 of a filter housing 4 is sealed with a seal ring 8. The bag filter bucket 3 has a configuration in which a handle 10 is positioned inside a tip end portion of a cylindrical portion. The tip end portion of the cylindrical portion of the bag filter bucket 3 is brought into contact with a position restricting portion 51.
