HEAT- AND MASS-TRANSFER APPARATUS Russian patent published in 1997 - IPC

FIELD: heat- and mass-transfer apparatuses with phase contact reaction. SUBSTANCE: the offered apparatus has body separated by partitions with discharge holes into sections. Installed in zigzag manner in each section are three overlapping contact members with inclination at an angle of 30-45 deg. to horizontal plane. Installed in each section are vertical partitions with contact members adjacent to opposite sides. Vertical partitions together with body form inlet and outlet gas channels having ports made in their upper and lower parts, respectively. In this case, outlet gas channel of underlying section is connected with inlet gas channel of the overlying section, that in counterflow of phases in apparatus ensures direct-flow motion of flows of gas and liquid within each section and additional separation of liquid drops with turning of gas at inlet and outlet of the above indicated channels. Besides, packing may be made in form of separate sections, each made in form of opened from ends shell rectangular of polyhedral in cross-section in plan. Secured inside the sections (shells) are contact members and separating inclined and vertical partitions. EFFECT: higher efficiency. 3 cl, 2 dwg
