Plasma is current investigative technique forward position both at home and abroad as gas cleaning processing means, but is mostly in laboratory
Exploratory stage rests on theoretical research state.The main difficulty faced is that broad gap electric discharge needs very high voltage (in air
30kv/cm)；Laboratory can not almost be promoted in engineer application using organic gas, such as Ar (argon gas), He (helium) etc.,
And safety is very poor；In addition, conventional plasma generator to driving power require it is harsh, cause power supply is at high cost, the service life is short, effect
Rate is low.
Chinese patent (102007820 A of CN, June 18 2014 day for announcing) discloses a kind of plasma generator,
The plasma generator, which has, makees shell made of the ceramics of raw material sintering aluminium oxide, which has slit-like gas
Introduction part, and wherein it has been arranged in rows the gas discharge section in multiple holes.From gas introduction part to heating region top
The width in crack is 1mm.It is provided with the second discharge unit comprising be arranged in rows along the longitudinal direction of heating region
Hole, the length of diameter and 16mm of the hole with 0.5mm.It is 2 to 5mm rectangular cross-sectional that heating region, which has side length,
Face.Electrode is provided with opposed facing recessed portion on its surface.The power supply power supply obtained by the voltage of boosting 100V (60Hz)
About 9kV and electrode is applied to 20mA electric current.When importing argon from gas introduction part, even if electrode spacing reaches 4cm,
Produce plasma.
It can be seen that the gap between plasma generator is smaller, it is not able to satisfy industrial application requirement completely.In laboratory
It assists ionizing using gases such as Ar, He, although expanding the distance between electrode plate, is passed through gas higher cost, but also
It is easy to happen explosion, is not used to gas cleaning processing.
In air, so that gas breakdown ionization is generated large area cold plasma and need tens kilovolts of even kilovolts up to a hundred
High pressure.So requirement of the prior art to driving power is also extremely harsh, seriously hinders plasma technology and fired in large volume
Popularization, application in terms of coal smoke gas disposal.
