FIELD: technological processes.
SUBSTANCE: invention relates to reduction of toxicity of exhaust gases. Device (10) for feeding reducing agent (42) in system of reducing toxicity of exhaust gases (EG), primarily for feeding water urea solution for reducing nitrogen oxides in diesel engine EG flow, with tank (40) for reducing agent (42) and supply module (14) for feeding reducing agent (42) from its tank (40) via suction pipeline (16), mainly via electrically heated suction pipeline. Suction pipeline (16) layed outside tank (40) is connected to sump tank (12) located in bottom zone (44). There is heating device (30), mainly electrical heating device, in sump area (12) intended for heating this sump heating. At least one heating rod (36), mainly electrical heating rod, protrudes in to tank (40). At least one level gauge passes outside tank (40).
EFFECT: technical result is assurance of reliable reducing agent supply to EG toxicity reduction system, providing accurate determination and monitoring of reducing agent level and simple design.
