Description

1The invention relates to devices for contacting a gas or dust-gas stream with a liquid and can be used in chemical and other fields of industry for the presence of various heat and mass processes, in particular for cleaning gases from pierce, mechanical impurities and drip liquid

Purpose: Inventions - reduction of energy consumption while increasing the cleaning efficiency.

Fig, 1 shows the proposed device a longitudinal section; FIGS. 2 and 3 are sections A-A and BB in FIG. 1 respectively.

The device includes a gas supplying nozzle 1, one or several distribution sections of the irrigating forksunok 2 cross-section of the nozzle, in the gas supplying nozzle 1 a sectional conical vane swirler is placed, sections 3 of which are located in the individual gas supplying nozzles 4 and are separated by annular channels 5 connecting separators of 6 s. collectors 7. of a liquid outlet containing aerosols or droplets of solutions (trapped liquids). At the same time, the blades of the section 3 of the conical swirler are located tangentially to the surfaces of the fairings 8 connected to each section 3 of the conical swirler. In the upper part of the separator 6 are placed the nozzles 9 of the outlet of the purified gas.

The device works as follows.

Dust-laden gas or gas containing droplets of a solution (a captured liquid) is fed to the gas supplying nozzle 1, where it is simultaneously supplied through a spray nozzle 2 of the progFish liquid. The resulting gas-liquid flow is distributed in proportion to the cross-sectional area of the gas supplying nozzles 4, after which it enters the tangential inter-787882

blade channels of each section 3 swirl, while distributing along the entire height of each section 3 swirl. In the interscapular channels, a gas-liquid stream receives turbulent pulses. The resultant film of liquid, including aerosols, which is formed as a result of rotation

10 inner surface of sections 3 of a conical swirl, washes gas,. leaves the top of each section 3 into separators 6, is soothed and finally degassed onto their

15 cylindrical surfaces.

The purified gas escapes through the pipes 9, and the liquid containing particles of dust (or mechanical impurities) or solution droplets is discharged through annular channels into the collector 7,

In the proposed device, the total gasol-x-flow stream is divided into a series of streams, each of which extends to a height not exceeding 10 meters.

In addition, the flow distribution between sections allows the device to increase the load on the device for cleaning gases, the dust content of which is up to 100 g / m.
