KOCHETOV CENTRIFUGAL ATOMISER WITH OPPOSITE SWIRL FLOWS OF VZP TYPE Russian patent published in 2014 - IPC F23D11/04 B05B1/34 

FIELD: machine building.

SUBSTANCE: centrifugal atomiser with opposite swirl flows of the VZP type includes a housing with vortex chambers and a nozzle; the housing is made in the form of a connection pipe with a hole for liquid supply from the main pipeline and a cylindrical coaxial sleeve with an external thread, which is rigidly attached to it; in the above sleeve there in series located are conical and cylindrical cavities coaxial to the liquid supply hole, and coaxially to the housing, in its lower part, there connected is a nozzle made in the form of a two-stage centrifugal cylindrical swirler connected to an outlet conical chamber of the nozzle and separated from the liquid supply hole with a perforated partition wall fixed on the end surface of the swirler housing and facing to the liquid supply side; with that, the first stage of the swirler is located in its upper part and includes a cylindrical chamber, with a stock arranged coaxially in it, and with a screw plate fixed on it; besides, the stock is fixed in the centre of the perforated partition wall, and the second stage of the swirler is located coaxially to the first one and formed with the annular cylindrical chamber connected in series with the cylindrical chamber of the first stage of the swirler and equipped with tangential inlets for liquid supply through the cylindrical annular cavity formed with the swirler housing and the cylindrical cavity of the sleeve, and on the conical surface of the outlet conical chamber of the nozzle there is a screw thread with the flow swirling direction opposite to the direction of the two-stage centrifugal cylindrical swirler.

EFFECT: enlarging functional capabilities.
