Embodiment Construction
[0022] The invention is a device for generating low-temperature plasma by dielectric barrier discharge to treat harmful gases. In addition to using the device to generate ozone in the atmospheric environment, the device can also be used to treat toxic gases such as NO, HC, CO, organic waste gas, and PM. . combine Figure 1 ~ Figure 3 , the low-temperature plasma harmful gas treatment device of the present invention adopts a coaxial structure, the main part is composed of a central low-voltage electrode 17, a quartz medium 15 coaxial with it, and a high-voltage electrode 16 tightly wrapped on the outside of the medium, and the discharge channel is in the central low-voltage electrode. 17 and the discharge gap (1-3mm) inside the quartz medium 15. The structure of the central low-voltage electrode 17 made of stainless steel tubes is as follows: figure 2 As shown, the side walls at both ends are perforated, and the middle is sealed by a blocking plate 21. The high-voltage elec...
