FIELD: wastewater treatment plants.
SUBSTANCE: group of inventions relates to devices for filtration, prior to discharge of microparticles contained in exhaust gases and/or gaseous combustion products into atmosphere. Installation comprises a casing, which can pass along the discharge circuit for gas flow. Inside the casing there is a channel, along which the flow can pass on a perforated plate, having negative electric potential for radiation and scattering of electrons in the channel, which can be connected with particles (B) of the contaminant, carried with the flow, being the microparticles, passing a negative charge to them. Inside the channel downstream behind the perforated plate there is at least one accumulation plate, having positive electric potential, which is intended to attract and retain electrically charged particles (B) on the accumulation plate. Plant includes at least one current-conducting thread, which has negative electric potential, turned aside and is located near at least one corresponding hole in the perforated plate, as the main source of radiation and scattering of electrons, which can be connected with particles (B) carried with the flow, in fact near the place of their passage through the hole.
EFFECT: higher filtration efficiency, operational reliability.
