SU1607900A1 - Apparatus for cleaning gas - Google Patents

Abstract

The invention relates to the wet cleaning of gases and improves the efficiency of cleaning and cooling gas, reducing the specific consumption of water for cleaning and energy consumption for its transportation. The device comprises a gas supply nozzle 1, a confuser 2, a throat 5, a counter-current irrigation nozzle 6 and a diffuser 4. The cone angle of the confuser is made in the range of 8-12 °. The gas supply pipe is made tangential and is located from the narrowed edge of the confuser at a distance of 15-20 neck diameters, and the irrigation nozzle is located from the narrowed edge of the confuser at a distance of 1.5-1.8 neck diameter. The above arrangement of the apparatus makes gas cleaning in a swirling flow with repeated recirculation of the liquid into the flow in the volume of the Venturi tube. 2 Il. 3 tab.

Claims (1)

Claim A gas purification device comprising a gas supply pipe, a confuser, a neck, a diffuser, a gas pipe, an irrigation nozzle oriented against the flow on the axis, characterized in that, in order to increase the efficiency of the gas cleaning process, the taper angle of the confuser is made in the range of 8— 12 °, while the gas supply pipe was brought tangentially and located from the smaller base of the confuser at a distance of 15-20 neck diameters, and the nozzle was placed at a distance of 1.5-1.8 neck diameters from the smaller base of the confuser.
