SU1292796A1 - Apparatus for bringing in contact vapour (gas) and liquid - Google Patents

Description

The invention relates to the instrumentation of mass exchange processes in the vapor (gas) - liquid system and can be used in the chemical, food and other related industries.

The purpose of the invention is to increase the separation capacity of the contact stages due to the intensive mixing of the liquid film.

The drawing shows a diagram of an apparatus for contacting vapor (gas) with a liquid.

The apparatus includes a cylindrical body 1, divided into sections 2 by horizontal partitions 3 with openings 4 for the flow of fluid, contact elements made in the form of tubes 5. The partitions 3 are provided with pairwise mounted coaxial guiding cups 6 and

7 with elastic elements 8. The upper parts of the tubes 5 and the cups enclosing them 6 c) 1 are filled in the form of cones with the same angle of taper, and the guide cups 7, covering the lower parts of the tubes, are made with openings 9 for the passage of fluid. Sections 2 are interconnected by means of connecting pipes 10.

8korpus of the apparatus provided by the fitting of the input 11 and output 12 of the liquid, as well as the fitting of the input 13 and output 14 of steam (gas).

The device works as follows.

Fluid through shtucer 11 is fed into the upper part of the apparatus and through the overflow holes 4 in the horizontal partitions 3 enters the annular gaps formed by the upper parts of the tubes 5 and the cups 6 that cool them, steam (gas) through the fitting 13 of the inlet and the connecting pipes 10 enter the upper parts of the sections 2 of the apparatus and transport the liquid coming from the annular gaps along the outer surfaces of the contact tubes 5 in the form of a liquid film.

At the time of the launch of the apparatus, the elastic elements 8 maximally press up the contact tubes 5, creating the possibility

for intensive flow of fluid, since the gaps between the upper part of the tubes 5 and the cups 6 are the largest. As the density of irrigation increases, the contact tubes 5 are lowered and the corresponding gaps are reduced, as a result of which the transportation of the liquid phase slows down and the tubes 5 again rise under the action of elastic elements 8.

Thus, during the operation of the apparatus, the contact tubes 5 oscillate, which significantly increases the separating ability of the contact stages due to the intensive mixing of the liquid film, accompanied by the active renewal of the contact surface and the increase in the residence time of the reactants in the working volume of the apparatus. The liquid phase entering the glasses 7 flows through the openings 9 to the partitions 3, which prevents the formation of stagnant zones of the liquid. The contacted phases are removed from the apparatus through nozzles 12 and 14.
