FIELD: building, ventilation.
SUBSTANCE: the invention relates to the area of utility equipment of industrial buildings, can be used for equipping industrial objects containing air contaminated with particles. The system of ventilation of industrial objects contains local polluted air suctions and an air pipe line connecting them with a suction nipple of a forced-draught fan of a boiler; the air pipeline is provided with a local bend facing down, for gathering solid, condensing, and fluid fractions of polluting substances, which is removable and has U-shape or the half-circle form; to the lower part of the bend, drainages are connected using funneled nipples for collecting solid and fluid fractions of polluting substances. The technical result is increase in reliability and cost efficiency of the ventilation system of the industrial object.
EFFECT: increase in reliability and cost efficiency of ventilation system.
