Multiple Coupling Exhaust Treatment System: (DOC+DPF+SCR+ASC)

1. System characteristics

(1) Control PM and NOx at the same time to reduce tail gas emission.

(2) In terms of software control, independent DCU is used for closed-loop control of double NOx sensors, and the exhaust flow is directly collected by sensors. The control accuracy of urea injection is high.

(3) DCU + remote monitoring system is adopted to monitor the operation parameters of the system in real time, find and solve problems in time.

2. Working principle of equipment:

(1) Doc: oxidize NO in the exhaust gas to NO2, and remove CO and HC in the exhaust gas at the same time.

(2) CDPF: the captured carbon particles react with NO2 at low temperature to generate CO2 for discharge.

(3) SCR: the catalyst will react with NO and NO2 in ammonia and nitrogen oxides to produce harmless nitrogen and water.
