FIELD: chemical industry; petrochemical industry; heat-and-power engineering and other industries. ^ SUBSTANCE: the invention is pertaining to distributing-contacting devices for the mass-exchange devices and may be used in chemical industry, petrochemical industry, heat-and-power engineering and other branches of industry. The distributing-contacting device contains a distribution plate supplied with a screen with holes, overflow branch-pipes, overflow devices, deflecting shields, perforated truncated cones. The perforated truncated cones are made out of a sheet of no more than 1 mm thick with shutter-type splits of a width -"S" equal to 0.3-0.5 mm, and with a step not exceeding the thickness of the sheet and with an inclination in direction of the liquid motion at an angle alpha equal to 30-45°, the ratio of the length "1" to its width "S" is from 13 up to 25, a direction of the shutter channels to the horizontal axis of coordinates is at an angle beta is equal to 30-45° and the overflow branch-pipes. At that for the packed columns on the ends of the drain branch-pipes at the calculated space intervals there are spray washers, and for plate-type columns the liquid from the drain branch pipes is fed onto an underlying sheet of a plate through a hydraulic lock. The presented distributing-contacting device ensures a high efficiency of the mass-exchange parameters in a wide range of a stable operation of packed columns and in the plate column apparatuses. ^ EFFECT: the invention ensures a high efficiency of the mass-exchange parameters in a wide range of a stable operation of the packed columns and the plate column apparatuses. ^ 3 cl, 3 dwg |
