HYDRODYNAMIC DUST SEPARATOR Russian patent published in 2009 - IPC B01D47/06 

FIELD: process engineering.

SUBSTANCE: invention can be used in various industries to clean gases of dust-like particles, to cool hot gases containing organic components and to extract viscous and low-viscosity hydrocarbon fractions by condensation. Proposed device comprises housing with its bottom accommodating gas feed branch pipe and diffuser with bubbler dispersing toothed web. Housing top accommodates drop baffle and gas discharge branch pipe. It comprises also branch pipe intended for feeding washing fluid and branch pipes arranged at different levels to discharge it therefrom. Housing expanded top part makes with center part an annular manifold communicated with washing fluid feed branch pipe. Housing central part accommodates film-type sprinkler arranged along housing axis and slot disperser mounted above the former, both being communicated via radial pipes with annular manifold. Film-type sprinkler and slot disperser are arranged to move along vertical. Gas feed branch pipe flow section area makes 0.1 to 0.35 of housing central part inner section area.

EFFECT: higher efficiency, reduced power consumption.
