KOCHETOV'S CONTACT HEAT-EXCHANGER WITH ACTIVE NOZZLE Russian patent published in 2014 - IPC F28C1/02 F24H1/10 

FIELD: machine building.

SUBSTANCE: in contact heat-exchanger each sprayer of the sprayed cooling water supply contains two coaxial cylindrical bushings, at that in the bushing with minor diameter an coaxially with it the worm is installed; the worm external surface is in form of the spiral groove, in the worm the hole with screw thread is made, and in major diameter bushing and coaxially with it the nozzle is installed, it is rigidly secured in it via the sealing gasket. In the union the cylindrical hole is made coaxially, the hole transfers to axisymmetric diffuser that is connected with the cylindrical chamber created by the internal surface of the bushing with minor diameter, and end face of the worm; and to the end face of the bushing with minor diameter at least two inclined rods are secured; on each rod active sprayers are secured, for example, in form of blades resting by bottom part on stops secured on rods at right angle to their axes, at that the rod are inclined from the sprayer axis i.e. along cone surface, which tip looks towards bushing with major diameter.

EFFECT: productivity increasing of the mixing heat-exchange in the vessel.
