Description

(54) CONTACT DEVICE

one

The invention relates to contact devices for liquids, vapors or gases and can be used for mass transfer purposes in mass transfer processes such as dislocation, rectification, absorption and desorption.

A contact device is known which contains perforated elements that form corrugated sheets in the assembly, in the hollows and protrusions of which there are overflow devices that have been lowered into the groove I.

It is also known to include a device, including a housing, height-mounted contact plates, spaced between them, wire packages made of hollows, and overflow devices 2.

However, the known contact devices are not sufficiently effective due to a small contact zone.

The aim of the invention is to reduce energy consumption and increase efficiency by increasing the contact of the phases.

To achieve the goal in the proposed device, the upper edges of the overflow devices are located in the depressions of each package and connected to the lower plane of each depression, the middle parts of the overflow devices are located in the protrusions of the underlying package, and the lower ones are installed on a plate located under the lower package.

It is advisable to place the planes of each trough at an angle of 30-75 ° to the horizon, and provide plates with an annular segment.

FIG. 1 shows the proposed contact device, a longitudinal section; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. I; in fig. 4 shows a section B-B in FIG. one.

The contact device includes a housing 1, plates located therein, interposed between the plates, wire packs 3 connected to the pits 4, overflow devices 5, the upper edges of which are placed in the pits 4 of each pack 3 and connected to the bottom plane of each pit; the middle parts of the overflow devices 5 are located in the protrusions of the underlying package, and the lower ones are installed on a plate placed under the underlying package. The planes of each depression 4 are located at an angle of 30-75 ° to the horizon. The plates 2 are provided with an annular segment 6.

The plate can be made with a large hole, can have horizontally-spaced holes of any geometric shape, for example, cuts from 3 to 6 mm wide or round holes; these openings can be partially closed by means of stationary or moving elements placed above, and openings with an inclination can also be made.

Parallel to the plates at a certain distance are packages of wire 3, inclined at an angle with to the horizontal, made us 30-75 °, and having a height from 10 to 150 mm, mainly from 30 to 75 mm.

Contact device operates as follows.

The gas flows from the bottom towards the liquid supplied from above. At high steam rates, preferably from 3 to 15 m / s in the open section of the column, vapor and liquid dispersion is achieved at atmospheric pressure, as well as at a given relative aperture of the tray, preferably from 15 to 50 ° / o. The initially established motion of the liquid and vapor phase in one direction at high speed and the subsequent resulting favorable separation of droplets in the phase flow cause good mass transfer.

Placed between the plates, bundles of wire 3 are divided by droplets of liquid as they flow upwards through a reflecting action. The specified placement of overflow devices 5 allows

arrange to drain the liquid, ensure an even separation of the liquid and eliminate contacting of the liquid returning to the lower plate with the main stream.
