Description

The invention relates to the purification of gases and can be used in vacuum devices used in metallurgy.

The purpose of the invention is to increase the cleaning efficiency.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

In a cylindrical housing 1 with a bottom 2, a lid 3, a tangential pipe 4 for supplying contaminated gas, a pipe 5 for evacuating the cleaned gas and fixing elements 6, the inner 7 and outer 8 shell are placed coaxially, the inner shell 7 is installed on the bottom 2 without a gap, and 8 - with a gap.

In the inner shell 7 in its upper part is the filter 9 fine cleaning

in the form of granules of reactive glass, in particular, high-porous silica, placed between mesh disks 10, the gap between the inner 7 and outer 8 shells is plugged from above, and along the perimeter of the inner shell 7 there are a number of radial holes 11 located at a distance from the bottom 2 exceeding the gap between the outer shell 8 and the bottom 2. The nozzle 5 of the clean gas outlet is connected to the hole in the cover 3. The bottom 2 and the cover 3 are made removable.

The contaminated gas enters the housing 1 through the tangential nozzle 4, passes into the gap between the inner 7 and outer 8 shells, bends around its lower end, and then through the hole 11 p filter 9 thin

Claims (1)

Effective gas cleaning in this device occurs during repeated flow turns due to the described arrangement of nozzles and shells that characterize the coarse filter, while reducing the flow rate in the plugged part of the gap between the shells, when throttling through the holes in the inner sheath and mesh disks, as well as passing through the bed of fine filter granules, where the intensive absorption of water vapor and the absorption of aqueous acidic solutions and gaseous particles of the reaction mixture occurs. ments. 1 claims A gas cleaning device comprising a cylindrical body with a lid and a bottom, equipped with a tangential nozzle for supplying contaminated gas and a nozzle for discharging the purified gas of a shell of different heights, coaxial with the gap, one relative to another installed in the housing, the outer of which is located with a gap relative to the bottom, and a filter fine cleaning, characterized in that, in order to increase cleaning efficiency, the gap between the shells is plugged from above, internally installed at the bottom without a gap, along its perimeter is made For radial holes located at a distance from the bottom exceeding the gap between the outer shell and the bottom, the fine filter is made in the form of granules of reactive glass placed between mesh disks and is located in the upper part of the inner shell, and the branch pipe of the cleaned gas outlet is connected to hole in the lid above the fine filter.
