ATTACHMENT FOR HEAT EXCHANGERS Russian patent published in 1999 - IPC

FIELD: heat exchange processes. SUBSTANCE: invention is related to heat exchangers with fluidized three-phase layer. It may find use in chemical and other industries. Outer surface of attachment is made in the form of sides symmetric with reference to horizontal area of largest section. Rotation axis of attachment passes through centers of regular polyhedrons located on opposite parallel planes. Form of largest section provides for filling of space of fluidization zone. EFFECT: creation of stable hydrodynamic state of developed fluidization with countercurrent flow of liquid and gas and diminished longitudinal mixing to ensure more complete extraction of absorbed component from gas phase. 1 dwg
