Problems solved by technology

However, the plasma generating device that uses contact glow discharge to generate plasma is generally composed of a special anode platinum electrode and a carbon rod cathode. Although this device generates plasma under appropriate conditions, it can induce the degradation of organic pollution in water bodies. However, due to the small discharge area, the ability to treat sewage is poor. At the same time, because there is only one discharge point, the current of the whole device is low, which is not suitable for industrialization.

Embodiment Construction

[0014] The contact glow discharge plasma generator includes an electrode carrier, a cathode and an anode. The electrode carrier 1 is a cylindrical polytetrafluoroethylene rod with a diameter of 6 cm, and the height can be selected according to actual needs. A hole with an inner diameter of 1.3 cm is inserted in the center of one end, and the cathode carbon rod 2 is inserted into the hole so that the length of the carbon rod outside the carrier is 3-7 cm; the thickness of the lower end of the carbon rod is 0.5-2 cm, and the diameter is 0.5-2 cm. The 3-6 cm disc-shaped graphite sheet 3 constitutes a sheet-shaped graphite cathode. Along the circumference 1 cm away from the cross-sectional edge of the PTFE rod 1, six holes with a diameter of 0.6 cm were opened, and the anode platinum electrode 4 was inserted into each hole, and the anode platinum electrode 4 was exposed at the lower end of the carrier 1 by 0.5- 1 cm. The platinum electrode 4 is to insert a platinum wire with a diamete...

Abstract

The invention provides a contact glow discharge plasma device, connecting several anode beams together in parallel and combining them with the cathode into a plasmas 'brush', having many discharging points and large discharging region, thus increasing the current of the whole device, effectively raising degrading efficiency, and simultaneously the invention has simple structure, operating convenience, and low price, suitable to industrialize.

Description

Technical field [0001] The invention relates to a plasma generating device, in particular to a contact glow discharge plasma device. Background technique [0002] At present, plasma technology is widely used in metallurgy, chemical industry and other fields, and its application in water treatment technology is more prominent. However, plasma generating devices that use contact glow discharge to generate plasma are generally composed of a special anode platinum electrode and carbon rod cathode. Although this device generates plasma under appropriate conditions, it can induce degradation of organic pollution in water. However, due to the small discharge area, the ability to treat sewage is poor. At the same time, because there is only one discharge point, the entire device has a low current, which is not suitable for industrialization. Summary of the invention [0003] The purpose of the present invention is to provide a contact glow discharge plasma generator with many discharge ...
