A MULTILAYER NOZZLE Russian patent published in 2004 - IPC

FIELD: petrochemical and gaseous engineering industries. SUBSTANCE: the invention presents a multilayer nozzle, that may be used in petrochemical and gaseous engineering industries, in particular as a separation, contact and sectionalized nozzles of heat-mass exchange apparatuses. The multilayer nozzle may be used in processes of a contact interaction of phases mainly in the gas-liquid separators and the immiscible liquid mixtures sectionalizers mainly of a horizontal type. The nozzle contains the frame lattice packages with flexible contact members, fastened in the frames with the help of fixing arms. At that each flexible contact member is made out of a porous braid made as a spiral forming a row of alternating vertical rod-type contact members, in turn connected among themselves in their upper and lower parts in the points of fastening to the frame by the fixing arms. The porous braid is hollow and the vertical rod-type contact members in the nozzle cross-section are located on equilateral triangles with a step equal to or less than two diameters of the braid. At that at least one frame located on the side of the oncoming phases is supplied with the hollow contact members, and the fixing arms are bent or stamped from the transverse parts of the frames and their length corresponds to a space between the contact members. At the phases passing through the nozzle the good wettability of the contact members and a liquid drainage through them is ensured. EFFECT: the invention allows to ensure a good wettability of the contact members and a liquid drainage through them. 3 dwg
