For efficient separation of liquid heterogeneous systems in oil and gas industry, various types of sedimentation tanks, separators, hydrocyclones, etc. are used, the principle of which is based on gravitational and centrifugal separation of heterogeneous masses of different densities. In order to ensure the best hydrodynamic conditions for the process of suspensions separation in a hydrocyclone and to prevent clogging of the discharge hole, an apparatus that contains only the cylindrical part of the housing is proposed. The presence of a taper displacer ensures the maintenance of optimal hydrodynamic conditions along the entire length of the apparatus, from the inlet to the discharge hole. The taper of the displacer affects the distribution profile of the tangential velocities of the fluid in the near-wall region, ensuring the constancy of the velocity profile along the radius and the specific flow rate over the cross section of the apparatus. Basing on the results of studies carried out on a real product (a mixture of PVCR with water) at a pressure and flow rate corresponding to the production ones, an industrial prototype of the apparatus has been designed and produced.
