Paired parallel partitions are made with benches-deflectors whose planes are located above perforated pipelines and perpendicular to axes of pipeline holes. Deflectors may be made on partitions in form of wedges or truncated wedges whose lower faces are perpendicular to axes of pipeline holes, and bases are combined with partition plane.
