Problems solved by technology

[0004] However, in scenarios with high ion balance requirements or high humidity, the requirements for ion balance are relatively high. Since the ion concentration in the ion wind will decay with distance, the power frequency AC ion fan provided by the related technology cannot achieve high balance requirements or high humidity. Ion balance in high humidity scenarios, resulting in poor applicability

Abstract

The invention discloses a power frequency AC ion blower and an ion balance control method, belonging to the field of static electricity prevention and control. In the present invention, after the ion wind passes through the balance detection module, the detection signal generated by the balance detection module and used to describe the linear change caused by the gradient decay of the ion concentration in space generates an adjustment instruction; the adjustable voltage source adjusts the bias according to the adjustment instruction. The voltage is set until the ions of the ion wind are in balance, so that the application of the power frequency AC ion fan in the scene with high ion balance requirements or high humidity is realized, and the applicability of the power frequency AC ion fan is increased.

Description

technical field [0001] The invention relates to the field of static electricity prevention and control, in particular to a power frequency AC ion fan and an ion balance control method. Background technique [0002] With the increasing importance of static electricity prevention and control, more and more industrial scenarios require a static electricity prevention and control device to eliminate and prevent static electricity. [0003] The related technology provides a power frequency AC ion fan, which can eliminate static electricity by directly converting the mains power into an AC voltage of about 5 kV through a power frequency transformer and then connecting it to an arc discharge device to generate positive and negative ions and apply them to the flowing air. ion wind. [0004] However, in scenarios with high ion balance requirements or high humidity, the requirements for ion balance are relatively high. Since the ion concentration in the ion wind will decay with dista...
