The invention relates to instrumentation of the processes of absorption, distillation, and a number of other vapor (gas) - liquid flowing in the system.

The purpose of the invention is to improve the quality of the final product by intensifying the process of mass transfer.

FIG. 1 shows a jet-directed plate, a plan view; in fig. 2 - the same, longitudinal section

The jet-directional plate includes a base 1, equipped with notched elements 2, vertical transverse partitions 3, receiving 4 and drain 5 pockets, baffling elements 6 with edges 7 flanged upwards, return plates 8. Angle of bending of bore elements 2, overlapped in plan by baffling elements - Tami 6 increases in the direction of flow of the liquid stream.

The plate works as follows.

The vapor (gas) enters the plate through the slotted elements 2, made in its base 1, and flows in the form of jets through the liquid coming from the receiving pocket 4. The vapor-liquid mixture continuously strikes the vertical transverse partitions 3 This process partially separates the steam from the spray.

Part of the liquid is picked up by the outgoing steam flow and is carried to

baffling elements 6 with flanged edges 7, where inertial phase separation takes place, as a result of which steam is directed to the overflowing plate, and the liquid, of the stack along return plates 8, enters the entrance of the corresponding section of the plate. Thereby, the liquid is repeatedly contacted with an upward, vapor flow, which minimizes the likelihood of bypassing the interacting phases.

In addition, the varying angle of the bending of the slotted elements contributes to a significant increase in the supply of liquid on the plate, which provides a deeper cleaning of the product. After passing through the working volume of the apparatus, the vapor phase is removed from the upper part of the column, followed by condensation, and high boiling components are removed with bottom residue

Invention Formula

Jet-directional plate on ed. St. No. 1101244, that is, so that, in order to improve the quality of the final product by intensifying the mass transfer process, the angle of bending of the slotted elements, which are blocked in terms of the baffle elements, increases in the direction of movement of the liquid flow.
