FIELD: process engineering.
SUBSTANCE: invention relates to collection of dust produced by web-formers. Proposed method comprises sucking dusty air into dust bag inlet, accelerating air, feeding swirling flow into chamber, forcing water into air, swirling air, water and dust, and discharging air mix from said bag. Dust collecting bag comprises air passage including dusty air inlet. Note here that water is not forced in said inlet Besides, this device includes vortex chamber formed by outer wall and guide vane, water injector arranged at outer wall to force water into said central vortex chamber and chamber discharge outlet communicated with water and air separator.
EFFECT: higher quality of dust separation.
