FIELD: machine building.
SUBSTANCE: invention relates to cross current packed heat-mass exchange towers, in which carried out processes of liquid-steam mixtures rectification separation, liquid-steam mixtures distillation, liquid-gas mixtures absorption separation. It can be used in oil processing, petrochemical, chemical, gas, food and other industries. Mass exchange tower with cross current of liquid and gas (steam) phases of “PETON” system includes housing, raw material supply union, distillate and residue vapors output, input of irrigation and vapors, cross current nozzle section, separated by height with horizontal support partitions, mated with liquid distributors made in form of set of steps, each of which is made of two conjugated face and drain plates, limiting cross current nozzle section, forming rectangular pocket in normal cross section. Step drain plate is equipped with perforated round holes, in each of which positive buoyancy rod is installed with possibility of free movement.
EFFECT: technical result is development of highly efficient mass exchange column, in which sharp change of liquid phase flow rates is possible, providing at that considerable expansion of device stable operation range, and possibility to use of contact devices with different number of flows in single device.
