The outer shell is secured to the inner one with a spaced relation to the plate cloth. The inner diameter of the ring space between the shells is 0.7-0.95 of the outer one. Depending on the method of circulation of phases to be separated, blade swirler can be positioned on the inner shell at its bottom part. In addition, outer shell can be provided with at least two rows of pinches with bents arranged at different levels. The direction of bents of one of the row is opposite to the direction of bent of the other one. The bottom rows of the pinches are arranged at the level of outlet section of the inner shell at the height no more than 1/3 of the height of the separation members. The top row is arranged at the height of 2/3 of the height of mentioned separation members. In addition, the bottom row of the pinches can be made with flanging of their edges.
