FIELD: pipelines for feeding gas to electrostatic filter, systems with electrostatic filter and with pipeline for feeding gas to said filter.
SUBSTANCE: pipeline includes duct for inlet flow of gas with constant surface area of its cross section and receiving hood for gas with cross section gradually increasing towards electrostatic filter. At least one gas flow distributing member is arranged in enlarged zone of gas receiving hood with increased cross section area. Two vortex generating apparatuses are used for creating swirling behind their front edge; one vortex generating apparatus is arranged inside duct for inlet gas flow and second vortex generating apparatus is arranged in receiving hood for gas in front of flow disturbing member in direction of gas flow. Respective adding unit is mounted in zone near one or both vortex generating apparatuses.
EFFECT: improved efficiency of filtering gas.
