The utility model provides a system for controlling the level of static electricity in a fluidized bed and is applied to the technical field of electrostatic control. The system comprises two or more electrostatic control subsystems arranged at different bed heights, wherein each electrostatic control subsystem comprises electrostatic measurement equipment, a controller and ionic wind equipment; the electrostatic measurement equipment is arranged on the fluidized bed and used for detecting the electrostatic potential of the bed height of the electrostatic control subsystem; the controller is respectively connected with the electrostatic measurement equipment and the ionic wind equipment and used for controlling the ionic wind equipment to generate ionic wind; the ionic wind equipment is arranged on the fluidized bed and used for generating the ionic wind and sending the ionic wind into the fluidized bed. Aiming at the characteristic that the electrostatic potential in the fluidized bed can be changed in an ax
