Description
Technical field
The utility model relates to the fluidic device field of plasma, is specially a kind of atmospheric pressure single electrode low-temperature plasma jet device.
Background technology
Plasma is comprised of cation, neutral particle and electronics, general plasma can divide two classes: thermal equilibrium plasma and nonthermal plasma, nonthermal plasma had been both low temperature plasma, atmos low-temperature plasma is because gas temperature is low, electron temperature is high, and there are high activity excited state particle, atom and charged ion etc., be widely used in the various fields such as material surface modifying, sterilizing, microbiological treatment.Therefore, atmos low-temperature plasma obtains the concern of Chinese scholars day by day, and will have broad application prospects in various fields.Under atmospheric pressure, because working gas puncture voltage is relatively high, discharging gap distance is shorter, is generally a millimeter Centimeter Level, and belongs to interior processing mode because of it, directly affect shape, the size of processed article, again because if using plasma handled object, because wherein many active components and charged ion life-span are very of short duration, to such an extent as to the surface that does not also arrive object just disappears, cause treatment effeciency very low, therefore in many applications, be all very restricted.In order to address the above problem, people take atmos low-temperature plasma jet device, atmos low-temperature plasma jet is separated with electrode district by plasma slab, it can directly produce plasma jet in extraneous space, a kind of nonequilibrium state, class glow plasma body technique, can obtain at a lower temperature the required active particle of chemical reaction, therefore can directly process article, shape and the size of processed article are not affected simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of atmospheric pressure single electrode low-temperature plasma jet device, is not suitable with problem and the remote problem of processing of large-area treatment to solve traditional plasma.For achieving the above object, the utility model is taked following technical scheme:
A kind of atmospheric pressure single electrode low-temperature plasma jet device, by thering is the adjustable DC power supply of voltage (9), plasma discharge parts form, it is characterized in that: plasma (1) is to locate to penetrate at the taper mouth of pipe (4) of quartz glass tube (6), the length of this quartz glass tube (6) is 120mm, its one end is the taper mouth of pipe (4) that length is 2mm for 15mm diameter, and one end is that interior diameter is the circular port of 8mm, a draw point (2) that is connected to wire (10) is placed in the middle of quartz glass tube (6), draw point needle point diameter is 0.5mm, draw point needle point is placed in the taper mouth of pipe (4) end, from the taper mouth of pipe (4), locate 2mm, only allow the draw point needle point 6mm of place outside exposed, remainder is inserted in insulating case (3), insulating case (3) is inserted in again in the insulating plug that diameter is 8mm (5), insulating plug (5) is placed in the quartz glass tube (6) at cone shaped mouth 60mm place, there is one herein perpendicular to the gas inlet port of quartz glass tube (6), its diameter is 4mm, insulating plug (5) is placed in the right-hand member of air inlet, the resistance that the wire (10) that connects draw point (2) is 10M Ω through the circular quartz glass mouth of pipe with resistance value is connected, resistance is connected with the positive electricity end of DC power supply.
