Method and device for electrostatic elimination by optical ion

Abstract

The invention relates to a method for eliminating static by photoion and pertains to the field of static. The filament of the X-ray tube in the method adopts an adjustable direct-current preheat starting / working voltage or current and an X-ray tube with an annular anode, an end window launching structure and a large launching angle is taken as the X-ray generating source. The filament of the X-ray tube is connected to a positive direct-current starting voltage / a high direct-current working voltage, wherein, the cathode is fixedly connected with the filament. The anode of the X-ray tube is grounded. Soft X-rays are generated by the X-ray tube. The soft X-rays ionize the air around the substances on which the static is eliminated, so as to generate an ion halo with symmetrical positive and negative ions on the surface of the substance, thereby neutralizing the static charges on the surface of the substances on which the static is eliminated. The invention further provides a device for eliminating static by photoion. The X-ray of the device has larger output power, lower power consumption and excellent radiating effect, can be continuously used for a long time, can eliminate the static fast and has a wider application range. The device can be adjusted according to different substances / objects on which the static is eliminated, so that the quantity of X-rays emitted can achieve the best static eliminating effect.

Description

technical field [0001] The invention belongs to the field of static electricity, in particular to a device for eliminating static electricity. Background technique [0002] Faults and hazards caused by static electricity are commonly known as electrostatic disturbances. From a traditional point of view, it is one of the main inducing factors of fire and explosion accidents in thermal power, chemical, and petroleum industries; it is also a hidden danger factor for quality and safety accidents in the processing of textile industries such as flax and chemical brazing; or it causes electric shock to the human body. important cause of harm. Therefore, electrostatic protection in the process of industrial production is becoming one of the safety issues that are increasingly attracting attention and attention in various industries. [0003] The basic principles of electrostatic protection are: a. Inhibit the accumulation of static charge; b. Quickly, safely and effectively elimin...

AI Technical Summary

Problems solved by technology

[0008] 1) need wind source;

[0009] 2) The high-voltage discharge electrode is easy to absorb dust, resulting in a decline in the performance of static electricity removal, and it must be maintained frequently to clean the electrode;

[0010] 3) Ozone is produced, which corrodes peripheral equipment and is harmful to the human body;

[0012] 5) Static electricity on workpieces with complex shapes or structures cannot be completely eliminated

[0017] However, the focus of the X-ray tube in the above-mentioned technical solution can only be concentrated on one point, and the output power is relatively small. Although it has a good effect of eliminating static electricity when applied in the electronic industry, it cannot be used in other fields (such as medicine, chemical industry, plastics, etc.) In occasions where a large output power is required, it appears to be powerless, which limits its application range to a certain extent.
