Abstract

The invention relates to devices for contacting gas (vapor) and liquids in distillation, absorption or desorption processes, and can be used in the petroleum refining industry. The purpose of the invention is to increase the capacity and decrease the resistance of the plate due to the directional introduction and the possibility of free redistribution of the steam flow around the valve perimeter. This is achieved by the fact that the slots in the valve bead are made U-shaped along the lower and lateral sides of the beads, and the bend of the cut parts of the beads is made around the upper sides of the beads. On the rectangular valve, the slots with bending are made on the flanged sides of the valve, perpendicular to the drain septum, on the valve of a trapezoidal shape, the slot with the flexure is made on the flanged valve base facing the drain septum. 2 3.p. f-ly, 4 ill. i (L

The invention relates to devices for contacting gas (vapor) and liquids in the processes of rectification, absorption or desorption and can be used in the refining, chemical, gas and other industries.

The aim of the invention is to increase the productivity and decrease the resistance of the plate due to the directional input O and the possibility of free-flow redistribution1- and steam flow around the perimeter of the valve,

The plate works as follows.

The liquid enters the plate from the overlying contact stage and moves towards the drain partition of the overflow device 1. The pairs from the underlying contact stage enter through the openings 3 at the base of the 2 plates under the valve h, where the steam flow separates 60KOBT.IX and one central thread. The central flow of steam, directed to sliviog rotor 1, facilitates the transport of fluid to the overflow, and the lateral streams directed at an angle to the movement of the aircraft, provide compensation for the flow, increase the fluid retention and enhance the contact efficiency. phases.

with an angle to the valve plane, the cut-out parts of the beads 7 provide steam injection directed at a sharp angle to the plate, which helps to reduce entrainment due to inertial forces and increases the effect of compensating the flow. In this case, since in any part of the divided steam flow there is the possibility of free steam out through both the side and the front edges of the valve, the proposed valve design provides for self-regulation of the redistribution of the steam flow, which helps reduce the pressure drop across the plate,

(The flange of the cut-out parts of the bead around. The upper side of the valve forms under the claggan not vertical, but inclined bulkheads, which provide directional steam injection in c.aoii fluids, pressing steam jets to the web of the dish, which reduces the loss of liquid from the plate and increases the compensatory ability of side jets J; i consequently, contribute to 1 1-;: s11siiuyu G1producer} l1osti and ef- il (ivTiiriHocTn works; .1.1 j-apenhM, Besides, :(,. the rifles are left in place, tm; the porch of the fuse can be taken from under the valve. gu; H tiH,: unie redistributed; no steam flow under the valve, which should cause a drop in pressure drop across the plate.
