METHOD FOR HYDRODYNAMIC CLEANING OF PLATE EXCHANGERS AND PLATE EXCHANGER FOR METHOD IMPLEMENTATION Russian patent published in 2017 - IPC F28G13/00 F28F3/02 

FIELD: power industry.

SUBSTANCE: method for hydrodynamic cleaning of plate heat exchangers, made in the form of sections consisting of two connected plates with spherical recesses on their working surfaces, recesses of one plate enter the notches of the other plate, including the creation of a turbulized flow with individual self-organizing pulsating vortex structures under the action of the heat carrier main flow in the recesses, as well as of an additional jet bypass flow formed due to the bypass of a part of the main flow through bypass channels made in the meridian plane of recesses, from the increased pressure zones on the walls of the recesses adjacent to their outlet edges to the reduced pressure zones in the bottom of adjacent recesses.

EFFECT: as a result of complex hydrodynamic effect of single self-organizing pulsating vortex structures and jet bypass flow, continuous cleaning of the heat exchanger plate is performed, and its service life is increased, geometric parameters of tear-off holes on the plates, location and size of bypass channels are determined.
