The invention discloses an AdBlue filling system driven by compressed air. The AdBlue filling system comprises a compressed air source, an AdBlue container, an AdBlue controller, an metering solenoid valve, a mixing cavity and a jet nozzle. The compressed air source is connected with the AdBlue container, the output end of the AdBlue container is connected with an inlet of the mixing cavity through the metering solenoid valve, and the other inlet of the mixing cavity is connected with the compressed air source. An outlet of the mixing cavity is connected with the jet nozzle, the jet nozzle is located in an engine exhaust pipe, and the duty ratio of the metering solenoid valve is controlled by the AdBlue controller. The AdBlue filling system is easy to control and manage, an AdBlue supply pump is not needed, pressurization is directly performed on the AdBlue container through the compressed air to obtain constant pressure, and therefore accuracy of AdBlue metering jetting can be guaranteed. The AdBlue containe
