FIELD: machine building.SUBSTANCE: in centrifugal swirl atomiser containing casing, captive nut, insert with contracting along the flow tangential channels, vortex chamber, nozzle and disc adjacent to the insert end from side of the tangential channels; at that the insert and disc are made out of metal-ceramics; the entry edges of the tangential channels are rounded, the end surface of the captive nut has central hole axisymmetric to the casing, the hole has cylindrical and cone parts, and insert has at least three tangential channels located in plane at right angle to the casing axis, and vortex chamber connected with the tangential channels, coaxial with casing orifice in the bottom part of the insert, and disc adjacent to the insert end from side of the tangential channels at right angle to the casing axis; the liquid flow spreader is connected to the captive nut end axisymmetric to the casing, the spreader is in form of the perforated cone shell with base secured by screws on the end surfaces of the captive nut; at that tip of the cone surfaces of the shell is directed from the liquid vortex, and in spreader bottom part the spherical perforated segment is secured such that tip of the cone shell coincides with centre of the spherical surface of the perforated segment.EFFECT: higher efficiency of liquid atomising due to reduced hydraulic resistance of the atomiser at keeping the flow characteristics, provision for homogeneous mixing with the inflow medium.2 dwg |
