HEATING MODULE FOR EXHAUST-GAS PURIFICATION SYSTEM Russian patent published in 2016 - IPC F01N3/25 F01N3/20 

FIELD: gas industry.

SUBSTANCE: invention relates to systems for treatment of exhaust gases of internal combustion engine. Heating module for an exhaust-gas purification system, connected to outlet of an internal combustion engine, comprises a catalytic burner, with a hydrocarbon injector (14). After nozzle (14) in direction of flow of exhaust gases there is oxidation neutraliser (12). Heating module (1) has main channel of exhaust gases (2), auxiliary channel (3) comprising catalytic burner (12, 14), as well as device (4, 5) for controlling mass flow of exhaust gases, flowing through auxiliary channel (3, 3.1). According to first version, main channel (2, 2.1) at inlet of heating module (1, 1.1) has bypass pipeline section (6, 6.1, 6.2), equipped with bypass holes (7, 7.1). In main channel (2.1) there is guide partition (16), having a spiral shape on at least separate sections, owing to which exhaust gas flow along main channel (2.1) is given a rotary motion. According to another version it is provided, that auxiliary channel 3 on inlet side and outlet side has, respectively, extending from main channel 2 in radial direction of discharge chamber 8, and between said discharge chambers 8 located parallel to main channel 2 of heating module 1 there is a section of auxiliary channel 11 with oxidation neutraliser 12.

EFFECT: when using invention heater design becomes more compact.
