Description

The invention relates to devices for contacting a gas or dust-gas yukka with a liquid and can find application in the chemical and other industries in order to carry out various tenlo and mass transfer processes.

The aim of the invention is to reduce energy consumption while increasing the cleaning efficiency.

FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The device includes a housing with a gas-supplying pipe 1, in which a sectional conical vane sealer 2 is installed, consisting of three sections 3-5 arranged one above the other (there may be two or more sections). Section 3 of the swirler is made in the form of a solid conical shell. Sections 4 and 5 are made of blades 6 arranged tangentially or at some angle to the side surface of the side of section 3, under which the fairing 7 is placed, additionally equipped with a nozzle 8 for draining the liquid.

The irrigating fluid is fed to the device through a pipe 9 and a nozzle 10. In the upper part of the device, an outlet pipe 11 is placed, the lateral surface of which forms with the side surface of the gas supply pipe 1 and the partition 12 a drain pocket for draining the separated liquid through the pipe 13 to the exhaust manifold 14 fluid.

The device works as follows.

Dust-laden gas or a gas containing droplets of a solution (a captured liquid) is fed to the gas supplying nozzle 1, where simultaneously a liquid is supplied through the nozzle 9 and the irrigating nozzle 10. The resulting gas-liquid flow enters the tangential interscapular channels of sections 4 and 5 of the swirler 2, through which it acquires a rotational movement inside the swirler. As a result of the rotational movement, centrifugal forces arise, which press a film of fluid against the avihritel. On the other hand, this film is affected by the force of the tin

the torus is not overcome by the energy of the upstream gas flow due to the fact that the bottom section 3 of the swirler is made in the form of a continuous conical shell, which creates a zone of aerodynamic shadow, as compared to the upstream gas flow. As a result, the rotating liquid film forms a descending swirling flow, with which the bulk of the liquid enters the lower section 3 of the conical swirl 2, from where it goes through the nozzle 8 from the device to the collector 14 of the liquid outlet. Thanks to the conclusion of the main mass; liquids through the nozzle 8 into the ascending vortex yoke, rising in the direction of sections 4 and 5, the gas rushes free from most of the dropping liquid contained in it (dust or mechanical impurities). As a result, the energy consumption for raising the liquid to the upper edge of the swirler decreases, the critical irrigation density increases, and the separation efficiency increases. Passing through the outlet pipe 11, the cleaned GHZ is finally released due to the p.entropant forces from the remaining liquid droplets in it, which, falling on the wall of the pipe 1 in the form of a rotating film, drain into the cardman to drain it through the pipe 13 to the collector 14 of the outlet separated liquid.
