AI Technical Summary

Technical Problem

The nozzle assembly of the existing ion wind bar has problems with inconsistent ion concentration and balance during long-term use or under complex working conditions, resulting in uneven static elimination effect, local static electricity residue or excessive ionization.

Method used

An ion detection plate and a discharge intensity adjustment unit are added to the nozzle structure. The high-voltage generator is controlled by alternating positive and negative voltages. Combined with MCU and PID interpolation compensation, the discharge intensity of the ionization needle is dynamically adjusted to ensure consistent concentrations of positive and negative ions.

Benefits of technology

The stability of the output ion concentration and balance of the nozzle component is achieved, ensuring the uniformity and consistency of the static elimination effect, and avoiding local static electricity residue or excessive ionization.

Abstract

The invention provides an ion wind bar, a static elimination device and an ion balance degree adjusting method, a controller drives a high voltage generator to input alternative positive and negative voltages to each tuyere, a current ion balance degree value is obtained according to positive ion current and negative ion current input by the tuyere, and the current ion balance degree value is input to the corresponding tuyere; the tuyere comprises a supporting structure, an ionization needle, a discharge intensity adjusting unit and an ion detection plate, and the discharge intensity adjusting unit obtains a first discharge intensity value according to alternate positive and negative voltages and obtains a second discharge intensity value according to a current ion balance degree value. The ionization needle generates a first charged particle flow and a second charged particle flow respectively according to the first discharge intensity value and the second discharge intensity value, and the ion detection plate converts positive ions and negative ions into positive ion current and negative ion current; in the second charged particle flow, the positive ions and the negative ions are in an equilibrium state. Concentrations of positive ions and negative ions in the charged particle flow can be ensured to be consistent.
