SYSTEM FOR SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDES IN EXHAUST GASES OF DIESEL ENGINES Russian patent published in 2016 - IPC F01N3/21 B01J35/04 

Abstract RU 2576758 C1

FIELD: treatment plant.

SUBSTANCE: invention relates to cleaning of exhaust gases of diesel engine. System comprises neutraliser 1 for exhaust gas, catalyst 2, device 3 to store and feed urea, tube 4 for urea supply through nozzle 5 into pipeline 6 for exhaust gas. Tube 4 is made of non-magnetic material and represents zigzag with two elbows, between which there is magnetic ring 7.

EFFECT: technical result is increased rate of thermal decomposition of urea solution, higher efficiency of NOx reduction, wider temperature range of efficient interaction between nitrogen oxides and ammonia, and reducing emissions of unreacted ammonia.
