Organic gas separation membrane fixing frame structure

The utility model discloses an organic gas separation membrane fixing frame structure which comprises a base, side seats and an organic gas separation membrane shell, the base is horizontally arranged, the side seats are vertically fixed to the two sides of the top face of the base in the longitudinal direction, placing grooves are vertically formed in the front and back positions of the top faces of the side seats, and the organic gas separation membrane shell is arranged in the placing grooves. And the placing grooves on the two sides are respectively and transversely contrasted. The device disclosed by the utility model has the beneficial effects that after the organic gas separation membrane shell is transversely placed between the placing grooves at the two sides, the pressing grooves can be matched with the placing grooves to press and fix the organic gas separation membrane shell in a manner that the stud of the lifting assembly rotates forwards to drive the pressing seat to descend; in this way, the o
