A vapor-liquid contacting device comprises: a spherical cage having a movable disk located inside. A weight piece is attached to the disk. The center of gravity of the weight piece is located on the axis of the disk. During the operation of a packed tower, the upward force of the vapor flow will cause the weight piece to seek the lowest position inside the cage, and the disk will end up in the horizontal position. As the liquid falls on the top of the disk, it would be spread and fall around the edge of the disk to form a liquid curtain. As the liquid cascades down the tower, it would be spread laterally and achieve a good liquid distribution and a good vapor-liquid contact.
