Detailed description of the invention
Further understand for making to have architectural feature of the present invention and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
Embodiment 1
As shown in Figures 1 to 4, a kind of plasma waste gas purifying equipment, comprise upper bracket 1 and lower carriage 2, multiple discharge electrode 3 be arranged in parallel is provided with between upper bracket 1 and lower carriage 2, interstitial spaces is left between the discharge electrode 3 be arranged in parallel, the discharge electrode 3 be arranged in parallel is provided with the perforation 4 of some correspondences, is connected with some plasma electrically electrode structures between upper bracket 1 and lower carriage 2, and plasma electrically electrode structure passes from the perforation 4 discharge electrode 3 stacked up and down;
Plasma electrically electrode structure comprises connecting axle 5 and is arranged on the one or more gear 6 on connecting axle 5, the two ends of connecting axle 5 are connected with upper bracket 1 and lower carriage 2 respectively, gear 6 on connecting axle 5 is positioned at the perforation 4 on discharge electrode 3, on the same axis, gear 6 is parallel with the discharge electrode 3 at corresponding 4 places of boring a hole in perforation 4 opposite up and down on neighbouring discharge plate 3.
Leave gap between the hole wall of gear 6 and perforation 4, wherein, upper bracket 1 or lower carriage 2 are connected with the positive pole of extraneous power supply, discharge electrode 3 is connected with the negative pole of extraneous power supply, form high pressure between the hole wall of corresponding gear 6 and perforation 4, perforation 4 is low side, and gear 6 is high-pressure side.Low side is circular perforations (diameter of a circle is preferably 40mm-110mm), and high-pressure side and low side spacing are preferably 15mm-30mm, and waste gas vertically enters parallel discharge electrode 3.
