Abstract
Abstract The invention concerns a process for separating and/or precipitating of solid and/or liquid particles (disperse phase) from gaseous and/or liquid media (continuous phase) as well as for separating mixed gases (gas-gas-separation) and/or mixed fluids (fluid-fluid-separation) as well as for screening and/or classifying by means of a vortex chamber separator with suction tube 35. For decrease of flow resistance at generation of moment of momentum the contact zone between main flow and eddy is adjusted to cylinder casing that the tangential initial impulse in laminary bottom flow is increased by means of decrease of laminary bottom flow impulse, secondarily circulating in vortex chamber. For reduction of loss of impulse by means of dissipative drop of pressure in flow of main channel, laminary bottom flow is dynamically balanced with constant or mainly constant average main flow rate. Clean gas flow is passed through suction tubes 35 with increasing cross sections in outlet direction, that flow is affected by only little meridian deviations in zones of extremely high flow speed. The clean gas flow is passed along outside of suction tubes with increasing speed towards inlet sections.
