Abstract
The invention discloses a column-plate winding-pathway low-temperature plasma gas generator. One side of the plasma gas generator is connected with a power supply (1). A central section of the side which is connected with the power supply (1) is provided with an air inlet (2) and the central section of the other side is provided with an air outlet (3). The plasma gas generator uses two rows of needle electrodes as discharge electrodes. Pole groups of anodes (4) and cathodes (5) have an interval which is 30-50mm. The each needle pole column in the pole groups is arranged with the same interval, wherein the interval is 2-10mm. One separating column plate (6) is arranged every 2-5 needle electrode columns. A glass cement is used to seal space between the separating column plate (6) and a shell (7). In the invention, production is simple and costs are low. The uniform plasma gas with a high density can be generated.
Description
Technical field
The present invention relates to a kind of atmospheric low-temperature plasma gas generator,, form tortuous gas passage simultaneously, make higher, the more even distribution of working gas ionic medium volume density by stopping that column plate is divided into the arc chamber of a plurality of series connection with region of discharge.
Background technology
Plasma is called as the 4th attitude of material, is made up of a large amount of energetic ions, electronic molecules, neutral atom, excited atom, photon and free radical.Because its positive and negative charge number equates, so on macroscopic view, be electric neutrality.Along with the high speed development of modern technologies, plasma technology is widely used.Wherein, in the low-temperature plasma system, during up to 1000-2500K, other particle temperatures have only 300-500K in the temperature of electronics, and whole system still is in low-temperature condition.Non-thermal plasma trap is widely used at aspects such as material surface processing, catalysis, sewage and waste gas purifications.
The discharge type of low-temperature plasma can be divided into glow discharge, microwave discharge, corona discharge, dielectric barrier discharge, radio frequency discharge etc.Wherein, corona discharge device is simple, but discharging current is less, and plasma density is lower; In addition, owing to use needle electrode, strong especially near the regional electric field of electrode, cause plasma density inhomogeneous.Therefore, need to improve input power the density and the uniformity of adjustment working gas ionic medium body through design.For example, patent of invention CN1404349A is an anode with many groups nickel filament, and copper coin is a negative electrode, in reative cell, has produced the high concentration plasma, can be used for industrial treatment waste gas, sewage and water source purifying; The reative cell of utility model patent CN201726583U design then is made up of metallic plate and a plurality of sheet metal group that is arranged in parallel, has sawtooth, and the increase of sparking electrode number obviously improves the density of gas ionic medium body.Except needs improved plasma density, plasma uniformity also was the key factor that the low-temperature plasma generator design demand is considered.Such as, utility model patent CN201618509 has designed special punched-plate at the inlet channel of low-temperature plasma generator, has played reinforcement gas and has mixed, and increases the effect of the stroke of gas, has improved the uniformity of plasma distribution effectively; Utility model patent CN101930889A will contain the gas of plasma through shunt, and the ejection of diverse location in reative cell makes the distribution of plasma in the reative cell be tending towards even.But, up to the present, also do not see and utilize structural design to improve plasma density and inhomogeneity relevant report simultaneously.
Summary of the invention
The object of the invention is to provide a kind of plasma density big, and the low-temperature plasma generator that in working gas, is evenly distributed of plasma.Utilize column plate to separate multicell structure and the tortuous runner that is produced; Implement the discharge of series connection multicell; Prolong the time of staying of working gas in reactor simultaneously, strengthen the dispersion of plasma in working gas, thereby effectively improve the density and the uniformity of working gas ionic medium.If in the arc chamber that column plate is separated, insert the dielectric microballoon, then can realize efficient dielectric barrier discharge.
The present invention is achieved in that
(1) side joint of plasma gas generator has power supply, regulates power output through regulating input voltage, plays the effect of the density of adjustment working gas ionic medium body; The middle side part that the plasma gas generator connects power supply has air inlet, and there is the gas outlet at the opposite side middle part;
(2) plasma generator adopts two row's needle electrodes as sparking electrode, and anodal and negative pole utmost point group is spaced apart 30-50mm; Each needle-like pole equidistance is arranged spacing 2-10mm in the utmost point group;
(3) every separated 2-5 needle electrode pole is provided with a separation column plate; Seal with glass cement between separation column plate and the shell, can flow along separating column plate, form zigzag path to guarantee working gas.Working gas is because of separating the stopping with zigzag channel a plurality of discharged in series zone of flowing through of column plate, thereby improved the density of plasma in working gas; Simultaneously, gas has carried out sufficient mixing in complications in through the process of the region of discharge of a plurality of series connection, thereby makes the more even distribution of plasma in gas.
Characteristics of the present invention: plasma density can be regulated through the voltage of regulating DC high-voltage power supply in (1); (2) a plurality of region of discharges are connected, and have increased the density of working gas ionic medium body; (3) separate the zigzag channel that column plate forms working gas is fully mixed, make more even that plasma distributes in air-flow.
The present invention makes simply, and cost is low, can produce the high and uniform plasma gas of density.
