Existing high-frequency plasma is typically to be produced in the light fixture of earthenware or quartz glass tube, and this kind of plasma is
High-temperature plasma, by taking argon plasma as an example, its temperature can reach nearly ten thousand degree.Light fixture using ceramic making has cost
High, the sightless deficiency of plasma flame flow shape;The light fixture low cost, transparent that quartz glass makes, can be such that operator holds very much
Easily the pattern of observation plasma flame stream and position, facilitate operator to adjust various control parameters, to ensure that plasma possesses
Good flame shape.
Quartz glass has dielectric strength and extremely low conductance very high, is under high temperature, high pressure and high frequency, to remain to
Dielectric strength and resistance very high are kept, almost without dielectric loss in the frequency band applied, therefore quartz glass is excellent
High-temperature dielectric insulating materials, this be using quartz glass make high-frequency plasma light fixture main cause.
Crystal founds maximum continuous 1100 DEG C of the operating temperature of quartz glass, 1300 DEG C of maximum short-term job temperature, compound stone
The maximum continuous operating temperature of English glass only has 950 DEG C, 1200 DEG C of maximum short-term job temperature.And plasma maximum temperature nearly ten thousand
Degree, so, if cooling is insufficient, the light fixture that quartz glass tube makes is easy to because of high temperature scaling loss, failure.
In High-frequency plasma multifunctional powder production equipment(CN201110179097.3)During use, patented invention
People has found that original light fixture has many deficiencies, such as:Illuminant arrangement is repaired in vapor tight tank body, safeguards inconvenience, and the cooling of light fixture is adopted
With gas cooling, radiating effect is bad causes light fixture often to burn, and closed tank body absorbs the effective of energy of electromagnetic field influence equipment
The deficiency of the aspects such as power output, igniting inconvenience, has then done very big on empirical basis are summarized to original light fixture
Improve.
