The latter is communicated via lateral groove with mixing chamber connected with medium mix pipeline. Note here that functional cylindrical adapter is arranged at lower section of said taper casing. Said adapter is divided horizontally into two parts. Note here that top part abuts directly on said taper casing and is corrected via inclined different-diameter pipes with active nozzle and active liquid phase feed channel. Said lower section equal to taper casing main diameter comprises four radial nozzles arranged along the edges and one nozzle located in axis of functional insert.
EFFECT: higher efficiency, reliability, longer life.
