Abstract
A diesel engine high pressure SCR ventilation and voltage stabilisation system, comprising an SCR reactor (), an air intake pipeline () and an exhaust pipeline () respectively connected to an air inlet and an exhaust outlet of the SCR reactor, a pressure difference sensing apparatus (), and a control apparatus, a first control valve () being arranged on the air intake pipeline () and a second control valve () being arranged on the exhaust pipeline (), and the control apparatus being connected to the pressure difference sensing apparatus (), the first control valve (), and the second control valve (). The control apparatus controls the first and second control valves such that the pressure difference between the SCR reactor and the exhaust side of the diesel engine remains in a predetermined pressure difference range. The present system implements rapid ventilation and ensures precise control and stabilisation of pressure difference.
