JET TRAY Russian patent published in 1997 - IPC

FIELD: designs of mass-transfer columns for reaction of system gas(vapor)-liquid intended for the processes of absorption, rectification, gas scrubbing; applicable in chemical, petrochemical, gas and other related industries. SUBSTANCE: jet tray includes horizontal plate of circular cross-section installed in vertical cylindrical column with central vertical branch pipe. Installed axisymmetrically above central branch pipe is cap with perforations in lower part of side walls. Installed above plate is discharge tube. Transfer tube is tightly installed in tray plate. Upper edge of transfer tube is located above perforation in cap side walls. Half-circle steam branch pipe is installed axisymmetrically round central steam branch pipe. Installed above half-circle steam branch pipe is half-circle steam cap with perforations in lower part of side walls. Installed above tray plate between central and half-circle caps is horizontal additional perforated plate tightly attached to lower edges of central and half-circular caps with hole for transfer tube. Vertical partition is installed above additional plate. Perforations in additional plate are made in form of arched slots with convexity upward and axes directed from discharge tube to transfer tube. Perforations in additional plate are made in form of arched slots with convexity upward and axes directed from discharge tube to transfer tube. Perforations in side walls of central and half-circular caps are made in form of arched slots with convexity to outside and axes directed at acute angle to vertical downward. EFFECT: higher efficiency. 7 dwg
