The SIOT high-speed washer is a direct-flow wet dust collector, in which dust is collected by settling it on the wetted walls of the body under the action of centrifugal forces, as well as flushing the air with sprayed water. Water flowing down from the walls enters the screw conical bottom. Between the generatrices of this bottom through the inlet section, air is supplied to the washer, under the action of which the water entering the bottom is carried away by the air flow to the upper generatrix (in the direction of its rotation), breaks off from it and falls on the air stream entering the washer, is sprayed and carried into the middle of the washer. Due to these effects (centrifugal separation and air washing with sprayed water), SIOT high-speed washers are more efficient than film cyclones, especially when cleaning fine dust fractions.
SIOT high-speed washer (series 5.904-61) is recommended for cleaning dusty air in exhaust ventilation units from various types of wetted dust, with the exception of cemented and fibrous dust, as well as condensation aerosols.
