The application discloses a method and device for improving ion balance stability of an electrostatic eliminator, belonging to the field of electrostatic elimination. A set of electric reactance elements are connected in series between a low-voltage electrode and a grounding end of the electrostatic eliminator. By setting the electric reactance value of the electric reactance elements, the creeping distance or / and the electric gap between each high-voltage discharge electrode or between each high-voltage discharge electrode and the low-voltage electrode between the high-voltage discharge electrodes is adjusted, and the high-voltage amplitude is automatically adjusted, so that the potential difference between the high-voltage discharge electrode and the low-voltage electrode connected to the ground is a variable value. By forming a dynamic potential difference between the high-voltage electrode and the low-voltage electrode, which is associated with the ionization / discharge state, self-adjustment of the discharge intensity and dynamic balance of the positive and negative ion generation amount of the electrostatic eliminator are realized, and the unbalanced fluctuation between the positive and negative ions is suppressed. The operation of manually adjusting the ion balance on site can be omitted, and the use cost is saved. The application can be widely used in the fields of design and manufacture of various active electrostatic elimination devices.
