As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0023] As Figures 1-4As shown, the embodiment provides a gas cracking device, which includes an insulating outer cylinder 1, an alloy negative ring 2, an insulating support 3, a conductive column 9 and a plurality of positive tooth plates 5. The insulating outer cylinder 1 is a cylindrical insulating part, the inside of which is used to install other components of the device, and the function is to insulate the entire device from the channel in which the device is installed. The alloy negative ring 2 and the insulating support 3 are respectively installed in the insulating outer cylinder 1, the insulating support 3 abuts the rear end of the alloy negative ring 2, and the conductive column 9 is connected with the insulating support 3 and extends forward along the axis of the alloy negative ring 2. The positive tooth plate 5 is installed on the conductive column 9, and a plurality of positive tooth plates 5 are distributed along the extension direction of the conductive column 9, and a plurality of spaced sharp protrusions 54 are arranged on the side of the positive tooth plate 5, which is easy to discharge.

[0024] The insulating outer cylinder 1 and the insulating support 3 are made of high-quality materials with high insulation performance, acid and alkali corrosion resistance. For example, PR5 / FR4 high-strength resin material is used; according to different actual use scenarios, PEEK polyether ether ketone, XLPE cross-linked polyethylene material can be selected. The diameter of the insulating support 3 is the same as that of the alloy negative ring 2, the thickness of the outer circle edge is less than or equal to the thickness of the alloy negative ring 2, and the diameter of the center hole of the insulating support 3 is less than the diameter of the positive tooth plate 5, and the center hole is used to install and fix the positive component (the conductive column 9, the tooth plate center positioning terminal 6, etc.). For example, the insulating support 3 includes an insulating outer ring 31, an insulating inner ring 32 concentrically arranged with the insulating outer ring 31, and an insulating connecting rod 33 connecting the insulating outer ring 31 and the insulating inner ring 32, and the insulating connecting rod 33 is provided with a plurality of insulating connecting rods 33 uniformly distributed on the side of the insulating inner ring 32; wherein one end of the conductive column 9 is installed in the center hole of the insulating inner ring 32.

[0025] The alloy negative ring 2 is in a cylindrical shape, also known as an alloy negative cylinder or an alloy cylinder, and its length, diameter and wall thickness are determined according to the size and input voltage and power. The diameter (the same below) ranges from 30 to 500 mm; the length (also known as the height) is directly proportional to the diameter, that is, the larger the diameter, the longer the length, which is basically limited according to the golden ratio (length:diameter = 1:1.62). For example, if the diameter is 50 mm, the length is not less than 30 mm, and if the diameter is 80 mm, the length is not less than 49 mm. According to actual application, the material of the alloy negative ring 2 can be selected from aluminum-based alloy, zinc-based alloy and copper-based alloy; in specific applications, precious metals such as gold, silver and platinum can be selected for alloying, and cathode excitation elements such as lanthanum hexaboride (B6La) or lanthanum series metal elements can be added to improve the plume density and strength between electrodes and prolong the service life.
