Description

Be provided with the clarifier of wind wheel electrode discharge device
Technical field
The utility model relates to gas depoisoning purification techniques field, is specifically related to a kind of clarifier that is provided with the wind wheel electrode discharge device.
Background technology
The life style of contemporary people approximately has time of 60% to spend indoor people's all one's life, and the city dweller is up to 80% to 90%.Unless the enforcement control techniques, the air quality meeting degradation of the public places such as large-scale office, amusement, shopping, meeting, teaching not only spreads disease, and can make the people be in sub-health state.Air cleaning under the household condition is also extremely important.At present, city outdoor air quality is lower, affected by finishing, furniture, family expenses chemical products, and IAQ is poorer, and oxygen especially negative oxygen ion content is very low, and some pernicious gases in indoor concentration far away higher than outdoor.Room air pollution has caused people's concern day by day.For example, according to Chinese Center for Disease Control statistics, the number that China dies from room air pollution every year is more than 110,000, and the pathogenic number of room air pollution is more.Except the air cleaning of the large-scale enclosed environments such as house, aircraft, train, automobile, refrigerator etc. are narrow and small, air cleaning problem that seal under breathing environment also causes people's concern day by day.Certainly, at Code in Hazardous Special Locations such as hospital, laboratory, child rooms, air more needs to purify.
In existing air purifier, the clean-up effect of plasma air purifier is extensively approved, therefore, many conventional air filtration purifiers have also all increased prime plasma composite photocatalyst clean unit, strengthen sterilization, organic matter degradation and dust removing effects, extend simultaneously filter service life.For example the patent of invention publication number 00812887.1, a kind of air cleaner and plasma generating unit thereof are disclosed, namely adopted the so-called time to strengthen clean unit by discharge plasma in the super high efficient filter prime, plasma plays decomposing organic matter, kill bacteria and dust agglutination, super high efficient filter plays the effect of the remaining organic matter of secondary filter and micronic dust, yet, air-flow will be by fine and close super high efficient filter, gas-flow resistance is very large, need the relatively high power motor could obtain larger air-flow, the motor power consumption is large, and noise is high.
Corona discharge or dielectric barrier discharge type that the plasma generator that air purifier is used mainly is made of two sparking electrodes, the electrode that produces corona plasma is asymmetric, positive electrode is zigzag, star, prickle shape, fishbone, line electrode, pin electrode, belt electrode etc., and negative electrode is net electrode, plate electrode, template electrode, pipe electrode, cellular electrode etc.
For example Chinese invention patent application number is 200510114204.9, a kind of plasma discharge catalytic air purifier is disclosed, it is characterized in that, clarifier contains the plasma discharge catalytic district, this district utilizes plasma discharge to produce plasma and ultraviolet light carries out catalysis to semiconductor light-catalyst, producing hydroxyl radical free radical degrades and sterilization to pernicious gas, its corona electrode that produces plasma is one group of asymmetry electrode, adopt pin electrode as positive pole more, negative pole adopts plate electrode more, and semiconductor light-catalyst is TiO 2, ZnO, ZnS, Fe 2O 3, CdS, CdSe or WO 3Particle, or the complex form of above-mentioned catalyst.This technology adopts sharp or thin positive electrode, electric field enhancement effect by tip or fine rule makes its interval discharge of local on every side easier, form the local corona discharge region, initial effect still can, yet, tip or fine rule electrode discharge form, plasma nonuniformity on the one hand, average plasma density is low, is unfavorable for fully purifying air; Tip or the easy ablated rust of fine rule electrode not on the one hand, guiding discharge stops.The research test shows, individual month of tip or fine rule general not enough 3-4 electrode life.
the Chinese invention patent publication number is CN101920224A, a kind of metal tape-plate structure reactor is disclosed, utilize thin band electrode to replace most advanced and sophisticated and fine rule electrode, although can not effectively stop the generation of discharge ablation electrode, but, can not make the electrode rust after band electrode is ablated yet, therefore discharge can not stop yet, declaring effectively to extend the positive electrode life-span reaches three or four times, but, discharge type or corona discharge, region of discharge still concentrates on the local space at band electrode edge, Uniform discharge is not good enough, plasma density is on the low side, the ozone productive rate is but not low.
Dielectric barrier discharge easily obtains high-density plasma; better effects if to air cleaning; due to dielectric impedance the discharge current passage; protected electrode to avoid ablated; at the follow-on tests of several months in the time; almost not finding has electrode to be occured by the phenomenon of obviously ablation, can infer that electrode life will be very long, considerably beyond the electrode life of asymmetry electrode corona discharge.For example the Chinese invention patent publication number is CN1927408, discloses the low temperature plasma indoor air purification method that a kind of dielectric barrier discharge produces, and adopts the nanosecond pulse dielectric barrier discharge to produce plasma, resolving harmful gas, and purification efficiency is higher.Yet thread inhomogeneous electric discharge phenomena easily occur in dielectric barrier discharge, claim again streamer-discahrge or micro discharge, and thread Uniform discharge is poor, and in discharge wire, synthetic ozone efficient is high, easily causes ozone to exceed standard.
Summary of the invention
be not difficult when studying the plasma generator of various plasma air purifiers to find, nearly all to adopt fixing asymmetry electrode discharge type, due to point of discharge all the time at the taper place, the sparking electrode ablation resistance of taper is poor in addition, and this is guiding discharge inhomogeneous and electrode life of short basic reason, local discharge due to taper place electrode, do not produce plasma around another template electrode, and air-flow often advection cross space between two electrodes, therefore, the air of close template electrode is also failed fully to be purified by plasma and is just left plasma generator, air cleaning is not thorough, and this is also why part hole clarifier also will add the reason of rear class super high efficient filter, although super high efficient filter can play the double purification effect, the prime plasma purifying unit has also extended the life-span of rear class super high efficient filter, but, air-flow will penetrate fine and close super high efficient filter, gas-flow resistance is too large, need to use heavy-duty motor to drive air blast, both power consumptions, noise is large again, some products are in order to reduce noise and power, the clear-cut low-power motor that uses, although energy consumption and noise have all lowered some, but, sacrificed air supplying distance, air-flow is very low, air supplying distance is very limited, test shows, air supplying distance is substantially equal to " purification radius ", the purification radius of the air purifier of 30-40W left and right generally is no more than 2 meters on the market, zone beyond 2 meters does not observe clean-up effect substantially, and, zone higher than clarifier inlet/outlet air mouth does not observe clean-up effect yet.
The purpose of this utility model is to solve the problem of above-mentioned plasma air purifier and purification method, should obtain high-density plasma, stops again inhomogeneous thread discharge; The corona discharge form of low voltage drive relatively be should adopt, the life-span or the discharge non-uniformity problem that adopt tip or strip asymmetry electrode overcome again; Should reduce again air-flow by the resistance of purifier unit under the prerequisite of not sacrificing air filtering function, strengthen air supplying distance and cross-ventilation.
For reaching above purpose, the utility model obtains the discharge of high density homogeneous plasma by following measures: adopt the conduction wind wheel as an electrode of atmosphere pressure discharging, the rotation of motor-driven conduction wind wheel, make point of discharge can not rest on the fixing point of electrode, but be rotated in the electrode surface motion with wind wheel, thereby be beneficial to the generation homogeneous plasma, and play the guard electrode effect; The air-flow that the wind wheel rotation produces is through the region of discharge between fixed electrode and wind wheel electrode, dispel discharge wire, stop on the one hand the generation of thread inhomogeneous discharge, reduced ozone emission rate, also form eddy current at plasma slab on the other hand, not only avoid air from without plasma slab " escape ", also increased the move distance of air at plasma slab; Cladding of fiber on wind wheel blade plays adsorb organic compound, bacterium and micronic dust effect in the wind wheel high-speed motion, make adsorbate can be trapped in for more time region of discharge, fully decomposed by plasma, due to cladding of fiber and air-flow tangent, can not increase gas-flow resistance; Be coated with TiO on cladding of fiber 2Nano particle plays the auxiliary purpose that purifies air of photocatalysis; Fixed electrode arranges dielectric coating or sheath body outward, perhaps between fixed electrode and wind wheel electrode, dielectric layer is set, the barrier discharge current channel, can enhanced discharge intensity, obtain more highdensity plasma, in order to satisfy the requirement of high pollution gas cleaning, can not produce the arc discharge phenomenon again.
