Plasma hot air electret equipment

Abstract

The invention discloses plasma hot air electret equipment, and belongs to the field of electret equipment. The plasma hot air electret equipment comprises a rack, a hot air device, a lifting platform,a conveying device and a plurality of electret nozzle groups, the lifting platform, the conveying device and the electret nozzle groups are arranged on the rack, the multiple electret nozzle groups are arranged at the movable end of the lifting platform, and the fixed end of the lifting platform is connected to the rack. The conveying device is arranged under the electret nozzle groups, a plurality of electret micropore needles are arranged at the bottom of each electret nozzle group, and each electret micropore needle is communicated with the output end of the hot air device. The distances between the electret nozzle groups and the conveying device are adjusted through the lifting platform, so that the distances between the electret micropore needles and a base material is adjusted, andthe applicability to the plasma hot air electret of the base material can be improved. The plasma hot air electret time is prolonged, and the electret quality of a base material is improved.

Description

technical field [0001] The invention relates to the field of electret equipment, in particular to a plasma hot air electret equipment. Background technique [0002] At present, the industry mainly uses two methods of corona discharge and water electret to charge electret materials. Corona discharge is the use of non-uniform electric field to cause partial breakdown of air. The ion beam produced by corona discharge bombards the dielectric and charges it. It is the most widely used method in industry. However, corona discharge will cause discharge deviation due to the precision error of the gap between the high-voltage applied electrode and the ground electrode, resulting in uneven charging of the electret material, and the electret effect is not ideal; Ozone pollutes the environment and endangers human health; in addition, high-voltage equipment is expensive, and there are great hidden dangers in safe operation and management. In contrast, water electret equipment is not on...

AI Technical Summary

Problems solved by technology

However, due to the limited ultrasonic power and the small mechanical force, the liquid does not penetrate the electret enough. In order to achieve a better electret effect, corona charging is still carried out before liquid charging, which still cannot avoid the shortcomings of corona charging, and highly prone to bacteria
