With.The ionized gas that low temperature plasma intermediate ion, electronics, free radical, the molecule of excited state and atom are formed, is in sharp
Send out, the upper state of ionization is prone to react with the material contacted, and therefore, low temperature plasma is widely used in sterilizing
Sterilization, surface modification (improve the wettability of paper, thin film, textile and fiber, water absorption, printing and dyeing, cohesiveness and conduction
The character of the aspects such as property), thin film deposition, lithography, the field such as device cleaning, additionally, low-temperature plasma is also applied to sky
Gas purifies and in industrial tail gas process.
Non-thermal plasma trap processes the principle of pollutant: under the effect of extra electric field, and it is big that medium discharge produces
Amount takes energy electron bombardment gas pollutant molecule so that it is ionizes, dissociate and excites, has the most just caused the thing of series of complex
Reason, chemical reaction, make complicated macromolecule contaminant be changed into simple little molecule safe material, or make poisonous and harmful substance be transformed into
The material of the low evil of nontoxic or low toxicity, the removal so that pollutant are degraded；Take and can make with solid contaminants contact by electronics
Obtain solid pollutant charged, and in mutual collision process, be combined into bulky grain and be deposited on dust-collection element.At present, low temperature etc.
Ion technology, as a new and high technology with extremely strong potential advantages in environmental pollution treatment field, receives domestic foreign minister
Close the highest attention of subject circle.
Low-temperature plasma air purification technology is mainly made up of high voltage power supply and the plasma electric two large divisions that leaves the theatre, plasma
Ionized field part mainly have plate to template, line to template, for template and line to various structures forms such as barrel shapes, these structure shapes
The plasma electric produced under formula is left the theatre skewness, and there is the situations such as paradoxical discharge, most importantly: interelectrode electricity
Pressure generally point 12kV, 16kV to 42kV, produce ozoniferous ozone amount higher than 10kV high pressure and be far above national safety standard, and excess is smelly
Oxygen produces very adverse influence to health, and voltage is generally difficult to produce the uniform plasma of stable low temperature less than 12kV
?.

Microorganism is killed.Additionally, purifying ozone concentration at air port is 0.11ppm, this is less than the 1.5ppm of national safety standard.
Spacing between positive plate 20 and negative plate 30 is 5mm, ionization cavity degree of depth 18mm, DC voltage 9300V, frequently
Rate 30MHz, discharge power 0.18W/cm2, ionization cavity cross-sectional area accounts for the ratio of the plasma air purifying device gross area and is
0.45；Use GB/T18801-2015 " air purifier " and GB21551.3 " domestic and similar applications electrical equipment antibacterial, degerming,
The particular/special requirement of purification function air purifier " measure efficient compound air filtering screen filter efficiency and sterilizing bactericidal properties
Energy.Test result shows: single PM2.5 purifying rate is 93.4%, single purifying formaldehyde rate 92.6%, and single antibacterial, virus are only
Rate 97.3%.Purifying ozone concentration at air port is 0.10ppm, and this is less than the 1.5ppm of national safety standard.
By foregoing it can be seen that the first point discharge portion in the present invention and the T-shaped plate in the second point discharge portion
The argon-arc plasma field applied voltage producing the distribution of electrodes mode of T-shaped plate is lower, hence it is evident that less than 12kV, 16～42kV voltage, and
And the generation amount of ozone is substantially less than national standard, and single PM2.5 purifying rate is 90.3%, single purifying formaldehyde rate
89.9%, single antibacterial, virus purified rate 95.9%.In order to show the superiority of the present invention, the plate of same electrode area is to plate
Type low-temperature plasma device has been also carried out test to air purification efficiency, but, single PM2.5 purifying rate is less than 50%, single
Purifying formaldehyde rate 40%, single antibacterial, virus purified rate 50%, this is because low-voltage is hardly formed stable argon-arc plasma field,
And then cause purification efficiency the lowest.This explanation present invention is a kind of can to produce the most steady plasma air purifying device, no
But voltage reduction causes ozone to meet national safety standard, and purification efficiency is also above like product.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
