CONTACT PLATE OVERFLOW DEVICE AND CONTACT PLATE Russian patent published in 2008 - IPC B01D3/16 B01D3/20 

FIELD: mechanics.

SUBSTANCE: proposed heat exchange column contact plate comprises a casing attached to the plate base and defoamer made from permeable material, for example, a screen closing the overflow device casing inlet, the said defoamer being fitted inside the overflow device casing. Note here that defoamer lower edge is attached to the casing wall below the plate base level so that a defoaming space is arranged between the casing wall and defoamer surface facing the incoming flow. Defoamer upper edge is arranged above the level of gas-liquid mix on the said plate and defoamer upper part has a gas outlet. Contact plate is also proposed made of a base with overflow device of the afore-described design.

EFFECT: expanded liquid loads range at higher efficiency of heat-and-mass transfer on contact plate and in apparatus.
