OUTGOING GASES DESULPHURATION Russian patent published in 2012 - IPC B01D53/50 

FIELD: gaseous flow desulphuration.

SUBSTANCE: alleged invention relates to the method of desulphuration of the gaseous flow containing SO₂; the basic water flow containing negative ions selected from the group including carbonate, bicarbonate, hydroxide, sulfite and bisulphate is infed; the basic gaseous flow containing SO₂ is infed; the basic water and gaseous flows are brought into interaction resulting in attainment of desulphurate gaseous products including less than 40% of the basic flow containing SO₂, and the water product; the interaction is performed in the hydrocyclone unit; the hydrocyclone unit has the housing formed with a cylindrical external sidewall and furnished with at least one inlet aperture for the induct of the fluid medium and at least one whirling installment; the speed of passing of the gaseous flow inside of the hydrocyclone unit counts to 20 - 120 m/sec.

EFFECT: enhancement of hydrocyclone unit operation efficiency.
