Description

The invention relates to the design of contact devices for absorption and distillation columns and can be used in gas, oil refining and a number of other related branches and industries.

The purpose of the invention is to intensify the mass transfer process by ensuring that the base of the tray and the horizontal baffle plate are evenly supplied with liquid.

FIG. 1 schematically shows two adjacent contact stages of the mass transfer apparatus; in fig. 2 - a fragment of the base of the plate and the additional web; in fig. 3 - fragment horizontally (1 h) of a bump stop; in fig. 4-scheme of mounting i-o-horizontal bump stop in the apparatus.

The plate of the mass transfer apparatus contains a horizontal based 1 with contact elements made in the form of notches 2, directed along the movement of the liquid, a horizontal damper 3 with contact elements 4, directed in the opposite direction, DONO. leg 5 with contact elements (notches) 6, guide plate 7, as well as inclined bump stops 8. Horizontal bump stop 3 is equipped with radially arranged vertical partitions 9 Dividing it into sections, with the edge 10 of partitions 9 above the direction of plate 7 bent toward adjacent sections. The horizontal bump 3 is mounted on the rails 11 with the possibility of vertical movement. A horizontal base 1 and an additional zero 5 are mounted on a frame 12, rigidly connected to the cornea 13 and the inner pipe 14. 14. A liquid injection pipe 15 is installed above the guide plate 7. Perforations can be used as contact elements. At the same time, radial, annular and combined arrangement of slots 2 and 6, oriented in opposite directions, is possible.

The plate works as follows.

The liquid phase enters from the underlying plate on the guide plate 7 and moves along the horizontal base 1, interacting with the upward gas flow entering the contact zop through the slits 2 in cut 1. The direction of transport of the fluid coincides with the orientation of the slits 2. After passing the bottom 1 liquid phase enters the additional sheet 5, the perforations of which are oriented against the course of the liquid flow. Carried away from the base 1, the liquid phase falls on the horizontal bump 3

after which it is separated by paclon bump stops 8. Under the action of the energy of the gas jets, the liquid moves on the horizontal baffle towards the direction of the plate 7, which leads to an increase in the density of irrigation of the base 1. As the liquid phase accumulates on the base 1, its dip on the guide plate 7 of the underlying contact stage begins.

When the working volume is partitioned by radially arranged vertical non-enclosures 9, the liquid phase is supplied to the guide plate 7 by means of the mother liquor 15. In this case only part of the sections are irrigated, after which the liquid phase moves without mixing between the sections along the sheets and the horizontal striker 3. Above the direction By the bent plate 7 by the folded edges 10 of the vertical partitions 9, the liquid is deflected towards the adjacent sections. The number of sections included in sequence is selected depending on the required contact time of the interacting phases; The presence of the guides 1 1 provides the possibility of vertical displacements of the horizontal piping 3, which allows the liquid stock on the plate to vary.
