DEAERATION COLUMN Russian patent published in 2009 - IPC C02F1/20 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. Deaerator contains tank-accumulator with cone-shaped entrainment separator and installed above it column in form of water-jet ejector with water-feeding device, made in form of evenly placed on column section acoustic sprayers. Each of acoustic sprayers contains case 30 with placed inside acoustic fluctuations generator in form of nozzle 23 and resonator 18, pipes for air 20 and liquid 21 supply. Coaxially with case 30 bush 27 with upper 15 and lower 19 flanges is fixed rigidly. Lower flange 19 is rigidly fixed in turning, made in case 30. Ring volumetric resonator 18 is made in form of cup 22 with conic surface pressed on its bar. In rear part of resonator 18 fixing discs 25, 26, made in form of elastic petals, interacting with inner surface of bush 27 are placed. In lower flange 19 at least one nozzle 23 is placed at angle 20°÷40° to resonator 18 axis. Extension of nozzle 23 axis lies on circumference located in middle part of conic surface of resonator 18.

EFFECT: increasing productivity due to fine liquid dispersion.
