The specific embodiment
Referring to Fig. 1, Fig. 2, plasma burner 1 of the present utility model is provided with fuel nozzle 3, aid distributing pipe 2, plasma generator.Plasma generator is a glow discharge plasma generator 4, and electrode 9, external electrode 8 form reaction zone 5 between the two in being provided with in insulating boot 10.Interior electrode 9 is individually fixed on prelocalization plate 71 and the rear position plate 72 with the two ends of external electrode 8.The surface of interior electrode 9 is provided with block media 91.Prelocalization plate 71 is located in the inducer housing 6, which is provided with air admission hole 710.Rear position plate 72 is located in the outlet section housing 11, which is provided with venthole 720.Outlet section housing 11 links to each other with the fuel nozzle 3 of plasma burner by pipeline.
Referring to Fig. 3, external electrode 8 is a cylindrical shape, and interior electrode 9 is cylindrical, and interior electrode 9 is located on the axial line of external electrode 8.Electrode 9 has only a surface in columniform, is provided with block media 91 on this surface.Correspondingly, insulating boot 10 is a cylindrical drum, prelocalization plate 71 and rear position plate 72 are circle, and inducer housing 6 and outlet section housing 11 are formed by the cylindrical drum that the cylindrical shell of one section frusto-conical face shape and a section are used to install prelocalization plate 71 or rear position plate 72.
Referring to Fig. 4, external electrode 8 and interior electrode 9 also can be for plate shaped.External electrode 8 is provided with two.Interior electrode 9 is provided with one, is located between two external electrodes 8, and is equal to the distance of two external electrodes 8.Plate shaped interior electrode 9 has two surfaces, is equipped with block media 91.Between the external electrode 8, be parallel to each other between external electrode 8 and the interior electrode 9.At this moment, correspondingly, insulating boot 10 is the cylindrical shell of square frame shape for cross section, prelocalization plate 71 and rear position plate 72 are square, and the cross section that inducer housing 6 and outlet section housing 11 are used to install prelocalization plate 71 or rear position plate 72 by one section hemispherical dome shape cylindrical shell and a section is the cylindrical shell of square frame shape and forms.Above-mentioned square frame shape comprises rectangular shaped as frame, square shaped as frame, square square, the rectangle of comprising.
The surperficial set block media 91 of interior electrode 9, material is generally quartz glass or pottery, normally sintering or be bonded in the surface of electrode 9.The thickness of block media 91 is generally 1～3.5 millimeter.The material of external electrode 8 and interior electrode 9 is generally red copper or stainless steel.
