DISC SPRAYER Russian patent published in 2025 - IPC B05B3/12 

FIELD: heat exchange.

SUBSTANCE: invention relates to disc-type spraying devices for heat exchange and mass exchange processes between gas (steam) and liquid and can be used in gas, chemical and oil refining industries. Disk sprayer consists of a disk installed on a drive shaft, a concentric collar, a shell, through holes, a hole for the shaft, rigidly fixed blades installed on the lower side of the disk. Radius of the concentric collar is equal to half the radius of the disc. Shell height exceeds that of concentric collar. Diameter of through holes does not exceed three millimetres. There are smooth transitions from the disc surface to the concentric collar and to the shell. Jet of liquid is supplied to the rotating disc near the hole for the shaft, under the action of centrifugal force the liquid is distributed along the surface of the disc in the form of a film and moves to the concentric collar, on which it is sprayed, and the formed gas-droplet flow due to centrifugal force hits the shell, on which it is sprayed again . At that, double spraying promotes increase of liquid dispersion degree, increase of heat transfer intensity and increase of mass transfer intensity.

EFFECT: invention provides increased degree of liquid dispersion, increased intensity of heat transfer and increased intensity of mass transfer.
