The invention discloses an internet of things artificial intelligence-based efficient air dust treatment device. The device comprises a base and a second fan, wherein the top end of the base is weldedwith a blow-down tank, a first dedusting barrel, a second dedusting barrel and a control box are installed at the top end of the blow-down tank, the second dedusting barrel is located between the first dedusting barrel and the control box, a PLC intelligent controller and a wireless electric signal transceiver are respectively installed on two inner side walls of the control box, and the first dedusting barrel and the second dedusting barrel are internally welded with a water-proof shelf and a sealing board respectively; the treatment device is provided with an exhaust pipe, a return pipe, aprecipitating chamber, a detection chamber and an air vent valve. According to the treatment device, air is introduced into stored water at the bottom of the precipitating chamber through an air inlettube, then the air undergoes breathing washing, so that large mass of dust in the air is removed, the overall mass of the air and dust is increased, and the spraying and dedusting effect is better; and further, the device can be controlled remotely and intelligently through internet of things, a dust concentration sensor and a voice recognition module.
