Abstract

The invention provides a tail gas treatment control device of a diesel engine test bench, and belongs to the technical field of tail gas treatment equipment. The tail gas treatment control device of the diesel engine test bench comprises a tail gas treatment assembly and a dust cleaning assembly. The tail gas treatment assembly comprises a supporting plate, a bench gas guide pipe, a connecting pipe, a first gas detector, a urea metering injection pump, an oxidation catalyst DOC, a particle catcher DPF, a selective catalytic reduction device SCR, a PLC independent controller, a second gas detector, an exhaust chimney, a hollow threaded column and an inner threaded cover; the supporting plate is fixed to the end of the bench gas guide pipe; the connecting pipe is fixed between the bench gas guide pipe and the exhaust chimney; when the control device is used, dust on the inner wall of the exhaust chimney is scraped off by a scraping sleeve; then, the dust runs out through the hollow threaded column; and the control device improves the cleaning efficiency of the dust on the inner wall of the exhaust chimney.

Description

technical field [0001] The invention relates to the field of exhaust gas treatment equipment, in particular to a diesel engine test bench exhaust gas treatment control device. Background technique [0002] A diesel engine is an engine that burns diesel for energy release. The advantages of diesel engines are large torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also goes through four strokes: intake, compression, power, and exhaust. However, since the fuel used in diesel engines is diesel oil, its viscosity is higher than that of gasoline, and it is not easy to evaporate, but its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition of combustible mixtures are different from those of gasoline engines. [0003] At present, when the exhaust gas treatment control device of the existing diesel engine test bench needs to clean the dust on the i...
