Description

The invention relates to devices for contacting gas (vapor) with a liquid and can be used in mass transfer devices of chemical, petrochemical and a number of other related industries.

The purpose of the invention is to intensify the mass transfer process by increasing the contact surface of the interacting phases and reducing the hydraulic resistance.

Figure 1 presents the contact device, a longitudinal section; figure 2-node I, figure 1; on fig.Z - section aa in figure 2.

The contact device for mass transfer processes includes a shell 1 inside which the plates 2, swirlers 3 are installed, as well as overflow pipes 4 interconnected by means of cylindrical cups 5 equipped with tangential holes 6 arranged in staggered order one relative to the other in height five.

The device works as follows

The liquid phase coming from the underlying plate 2 through the overflow pipes 4 into the glass 5, due to the presence of

1. The gas flow, the passage of the swirler 3, acquires a rotational motion, picks up the liquid and disperses 5 of it into droplets. The contacting liquid flows along the walls of the shell 1 onto the underlying plate 2, from where it flows through the overflow pipes 4 into the next cup 5 with tangential ratios of 6 to further interact with the gas.

Arrangement of tangential holes in chess order, one relative to the other in height of glasses

15 provides a uniform distribution of the liquid phase over the cross section of the apparatus, which leads to an intensification of the mass transfer process by increasing the surface of the contact of the phases. Coincidence

20 of the direction of rotation of the gas flow with the direction of the input of the liquid phase through tangential holes in the glass allows to reduce the hydraulic resistance of a single contact stage and the apparatus as a whole. With counter-flow, conditions are created to increase the separation. the ability of the device by increasing the relative velocities of the mutual
