Abstract
The utility model relates to a low temp. plasma discharging tube. The deadening medium of the utility model uses the double layers of inner and outer tubular structure to be fixed coaxially. The external electrode adopts the ribbon form to be wound on the lateral surface of the outer tube; the internal electrode adopts the tubular or filiform structure to be arranged inside the inner tube. Water can air can pass through the inner tube, which can cool the internal electrode. The utility model can avoid the phenomenon of filiform discharge or partial discharge, and can make the discharge even. The utility model can fully use the energy of the active particle generated by ionization to improve work efficiency, and can prevent high temperature generated by continuous operation for a long time to lengthen service life. The discharging tube can be used in an industrial waste gas treatment apparatus, an ozone generating apparatus, etc.
Description
The utility model is a kind of discharge of plasma in low temperature pipe.
At present, the discharge tube that in device such as lower-temperature plasma industrial waste gas treatment, uses, its external electrode is generally tubulose, interior electrode is bar-shaped, and with insulating material such as earthenware etc. as single dielectric layer.Outer tubular electrode is enclosed within the tubulose insulating material outside.Thread tele-release or partial discharge phenomenon often appear in the discharge tube of this structure, make discharge inhomogeneous.In addition, when gas passed through region of discharge, molecule can be dissociated, and generates a large amount of free radicals or other active materials etc. simultaneously.And the region of discharge of outer tubular electrode is continuous, activates so these active materials will be subjected to electricity repeatedly, and up to flowing out discharge tube, its energy can not be fully used, thereby makes operating efficiency not high.In addition, when handling industrial waste gas, need large power supply with this discharge tube, and continuous operations bar-shaped in electrode generate heat easily, influence useful life.
The purpose of this utility model is to provide a kind of and can increases work efficiency greatly, and can be suitable for the discharge of plasma in low temperature pipe of high power CW running operating state.
The discharge of plasma in low temperature pipe of the utility model design is made of inside and outside electrode and deadening dielectric.Wherein dielectric adopts inner and outer pipe double-decker form, and ventilation space is arranged between the inner and outer pipe, and external electrode adopts belt-like form, and with the spiral-shaped outer tube lateral surface that is wound in, interior electrode adopts tubulose or filament, pipe the inside in placing.Inner and outer pipe is coaxial fixing at the place, two ends, and the gas that needs to handle can enter between the inner and outer pipe of discharge tube.Interior pipe can be ventilated or water flowing, so that internally electrode carries out air cooling or water-cooled.Its structure as depicted in figs. 1 and 2.
The discharge tube of the utility model design, its inner and outer pipe adopts insulating material, and as pottery or quartz, glass etc., length is generally 100～500mm, and wall thickness 2-3mm, the internal diameter of outer tube are generally 15～100mm, and interior external diameter of pipe can be 10～96mm.
The inside and outside electrode of this discharge tube can adopt stainless steel or nickel or other metal material, and banded external electrode width is 5-20mm, and as long as inner electrode diameter is less than inner tube diameter.Inside and outside electrode is connected with power supply respectively.
The discharge of plasma in low temperature pipe of the utility model design, because external electrode curl, each region of discharge has certain intervals, and the active particle in the gas has certain hour and pernicious gas molecular action in non-discharge area, makes the pernicious gas molecule produce sufficient chemical change.Like this, the energy of these active materials is fully used, consequently the clearance to pernicious gas greatly improves, and has promptly improved the utilization ratio of energy, has also improved the operating efficiency of handling waste gas.And because dielectric adopts the double layered tubular structure, the gas of processing has been avoided thread discharge or partial discharge phenomenon from two pipe intermediate flow mistakes, makes discharge evenly, also helps improving the operating efficiency of handling waste gas.Because internally electrode design has cooling device (interior pipe ventilation or water flowing), can avoid the high temperature that produces because of the long-time continuous running, increase the service life.
The discharge of plasma in low temperature pipe of the utility model design can be used for equipment for treating industrial waste gas, also can be used for ozone generating-device etc.
The structure chart of the discharge tube that Fig. 1 designs for the utility model.
Fig. 2 is the fork-shaped fixed support of inner and outer pipe at the two ends of this discharge tube.
Wherein, 1 is outer tube, and 2 is interior pipe, and 3 is external electrode, and 4 is interior electrode, and 5 is upper bracket, and 6 is lower carriage.
Embodiment: as shown in drawings, inner and outer pipe adopting quartz glass material, discharge tube length are 300mm, the internal diameter of outer tube 1 is 40mm, interior pipe 2 external diameter 10mm, and banded external electrode 3 adopts stainless steel material, bandwidth is 5mm, and with the spiral-shaped outer tube lateral surface that is wound in, pitch is 5mm.Interior electrode 4 adopts stainless steel tube, and overall diameter is 8mm, and pipe 2 is middle in placing.Upper and lower support 5 and 6 is made three pronged shape, and inner and outer pipe is coaxial fixing.This discharge tube can be used for the device of lower-temperature plasma industrial waste gas treatment.
