Corona discharge may be accompanied by high temperatures. Ceramic tubes can usually withstand certain high temperatures to ensure the stable operation of the equipment. The shape design of ceramic tubes can affect the form and effect of corona discharge. Ceramic tubes of different shapes may produce different forms of corona discharge, which requires precise control in some applications. Ceramic tubes usually have a certain resistance to chemical corrosion, because some chemicals may exist in the corona discharge environment. In general, ceramic tubes play an important role in corona machines. At the same time, the specific design and selection should be adjusted according to the needs of actual applications.

[0004] However, the existing corona machine ceramic tube has the following problems during operation:

[0005] (1) The surface shape of the discharge contact part of the ceramic tube of the corona machine will have a huge impact on the corona discharge process. The sharper surface can concentrate the electric field and promote the occurrence of corona discharge. However, the existing ceramic tubes do not take into account the influence of the shape of the contact part and the placement distance combination on the corona discharge process when designing.

[0006] (2) The internal structure of the ceramic tube of the corona machine will have a certain impact on the gas flow during the corona discharge process. However, the internal structure of the existing ceramic tubes is mostly rectangular, which cannot guide the gas flow well. Utility Model Content

[0010] Furthermore, the cross-sectional shape of the discharge groove is circular, triangular or rectangular.

[0011] Furthermore, the spacing between the discharge grooves at different positions is 2mm-5mm, and the corona ceramic tube discharge structure is designed by integrating a circle, a triangle or a rectangle.
