FEED OF STEAM INTO CONDENSATION CHAMBER Russian patent published in 2015 - IPC B01D47/05 

FIELD: process engineering.

SUBSTANCE: invention relates to air cleaning. In compliance with this method, steam is fed into condensation chamber composed by several serial condensation sections. Every said section comprises tubular case with dusty and/or smoggy gas flow inlet channel. Said chamber is equipped with steam feed means, refrigerator and circular condensate collector and cleaned gas flow discharge channel. Steam feed means is composed of hollow cylinder made up of two interconnected cylindrical shells, outer and inner, arranged with clearance to make the steam feed inner channel. Cylinder is arranged with radial clearance coaxially with tubular case. Holes are made at outer shell outer surface to communicate inner space of said channel with circular chamber composed by tubular case and hollow cylinder. Refrigerator is composed f a jacket coaxial with said case. At cleaning, gas flow is transformed from solid flow into hollow circular flow while steam for cleaning is fed into circular clearance between said shells and, therefrom, to said circular chamber. Heated refrigerator fluid is used for steam preparation.

EFFECT: higher efficiency of cleaning.
