DEVICE FOR GAS CLEANING FROM PARTICLES OF LIQUID AEROSOL Russian patent published in 2002 - IPC

FIELD: cleaning of gas media from fog aerosol whose condensation particles does not exceed 1 mcm. SUBSTANCE: device may be used in any industry whose production processes need said operation. The device has a body with branch pipes for intake of gas to be cleaned and branch pipes for discharge of cleaned gas, settling members in the form of thin metal tubes with perforated initial section. Relative length of settling tubes is taken equal to L/d= 250, and distance from tube inlet to perforation of initial section l= 7d. Installed at end of said initial section is resistance diaphragm. Hole sizes in tube walls are as follows: at distance 1=7d 2r₁=0.05d, and at distance of 20d from inlet 2r₂=0.1d. Holes are staggered with spacing by circular perimeter S₁= 0.6d and S₂=1.25d in direction of low. EFFECT: higher efficiency of cleaning due to use of properties of turbulent coagulation of particles at initial section of settling tube. 3 cl, 2 tbl
