For multi-stage cleaning, a battery of hydrocyclones, according to the invention, is formed from a number of sequentially located groups along the drain, gradually decreasing in size of parallel-connected hydrocyclones, the number of which in each group is twice as large as in the previous one. 12 One of the disadvantages of this battery is low lighting efficiency.

This is caused by the fact that the drain nozzle of each hydrocyclone of the previous group is connected to the feed nozzles of the hydrocyclones of the next group by a "tee" type connection.

In addition, the installation of such a battery of hydrocyclones is characterized by great complexity, which significantly reduces the manufacturability of its design.
