Description

Known rectification that;) e, 1 chats ko.pigchkozys ko.yunny have the disadvantage that. to work in limited gas velocity velocities from the column.

The described distillation column is: use; it works in a wider range of gas stabilities, and the container design can be used in pulsating columns, for example;), in air separation plants with this method of deep cooling.

FIG. I schematically izbrashey x.unna from the section and. K:}; e but section A- / 4; in fig. 2-plate sectional view and section IO B - B. and plan.

Flat plates 2 are welded inside the body / column, to which rigid drain pipes 3 .ia, Toro of diameter and gas-oil bore pipes 4 of large diagram are rigidly fixed. To the drain nozzles 5 at the bottom, the receiving glasses J for ironing, held by set screws 6, are movably fixed at the bottom of the column. Radially curved baffles 7 are rigidly attached to the bottom of the bottom plane of the plates in the center of the column.

 with nozzles are mounted inside the column in such a way that the drain nozzle 3 with the receiving cup 5 of the overlying plate 2 is concentrically inserted with mounting screws 6 into the gas-fluid pipe 4 of the underlying plate where the top of the cup 5 (liquid level) enters inside the gas-filling nozzle . An 8-sided version of the plate and pipe-shaped branch pipe “BeHTypii is shown in FIG. 2, where in S, a ceramic material made of ceramic, in the existing holes are inserted and strengthened the fusion pipe 9 with the receiving cup 10 and the gas-liquid patrubo) from 11 according to the “Ventlfi. The gas or vapor of FIG. I, coming from the bottom of the column into the space between the wall of the column and the surface

№ 129181

the gas-liquid pipe, as a result of a sudden narrowing in the concentric gap between the stept. 1 and the glass and the gas-liquid pipe or between the diffuser of the same pipe in FIG. 2, passes above the mirror of the liquid at high speed and carries the liquid from a small glass.

When leaving the gap between the nozzles, the gas-liquid mixture hits the bottom of the overlying tray and the visor 7. As a result of the expansion of the flow, the mixture in the center of the allotment space significantly reduces its speed and from this drop of liquid (phlegm) under the influence of gravity go to the bottom and flow down the drain nozzle into the receiving cup of the underlying plate, all the while keeping the hydraulic shutter of the drain nozzle closed, and the gas continues to move to the upper plate through the gap between the walls of the cup and hectare suction or a diffuser of the same nozzle - according to the type of “Venturi.

Subject invention

1. A rectifying and absorbing trailer column, operating on a continuous flow principle of phase interaction, consisting of a body and plates with gas-liquid and drain pipes, characterized in that, in order to ensure the operation of the column in a wider velocity range, gas in the plate , at the lower ends of the drain nozzles are fixed movable removable receiving glasses, the top of which enters inside the gas-liquid pipes.

2. The rectifying and absorption trash column in Section 1, is from the fact that the gas-liquid pipes are each made in the form of a “Venturi” pipe, in the confuser of which a glass pipe of the internal pipe.
