Non-driving continuous degasser

The invention relates to a non-driving continuous degasser. The non-driving continuous degasser comprises a shell and a semi-permeable membrane, wherein the semi-permeable membrane is connected with aconnecting end; the connecting end is used for connecting a gas transmission end; the shell is of a hollow structure; a supporting column is arranged inside the shell; the semi-permeable membrane isfixed on the side wall of the supporting column; the shell comprises a plurality of connecting pieces; the connecting pieces are arranged in the length direction of the supporting column; the plurality of connecting pieces are uniformly distributed in the circumferential direction of the supporting column; and the plurality of connecting pieces are arranged in the same spiral direction. Accordingto the non-driving continuous degasser, the collision between solid impurities in drilling fluid and the semi-permeable membrane is reduced, so that the damage probability of the semi-permeable membrane is reduced; and meanwhil
