Method, including procedure below：
Corona discharge and air ionization：High pressure is added on discharge plate 122, activated carbon composites 121 are grounded, in discharge electrode
Plate 122 is formed about uneven corona field, a small amount of charged particle existed originally in nature by electric field acceleration, after acceleration
Charged particle has very high energy, directly collides with gas molecule in motion process, high during collision
Energy electronics converts energy to the gas molecule in ground state, and ground state molecule obtains enough energy can be ionized, decompose, and be made
Gas molecule is ionized, and forms free electron and cation, while producing oxidizing species, the oxidizing species include
Ozone；
Particulate matter is charged to degrade with the ionization of VOCs gas molecules：Discharge plate 122 is nearby full of powered particle, in electric field
During well-regulated motion process is done under effect, electronegative particle is just attached on neutral corpuscle when running into the particulate for having neutrality,
Charge particles, i.e. electric-field charge are made, meanwhile, powered particle is attached on particulate during warm-up movement makes particulate negatively charged,
That is diffusional charging；Free electron or oxidizing species and VOCs gas molecule collisions, make VOCs gas molecule internal chemical keys
Fracture or homolysis and be dissociated into fragment group or atomic group；
Electrically charged particle thing is deposited and VOCs oxidative degradations：Electrically charged particle thing mutually collides aggegation and forms big particle, in negative height
Deposit on activated carbon composites 121 under the repulsion effect for pressing battery lead plate 122；Ozone enters activated carbon composites with air-flow
In, oxygen radical is resolved in the presence of catalytic substances, VOCs fragments group and atomic group are attracted to activated carbon composites
On 121, and by oxygen radical oxidative degradation, air is purified and by gas channel, the first exhaust vent 141, the second air-out
Discharged by perforation exhausting plate 2 in hole 142.
The preferably intensive negative high voltage electric discharge of the electrostatic precipitation of the present invention, adds negative high voltage, activated carbon pole on discharge plate 122
Plate 121 is grounded, and is thus formed about non-uniform electric field in corona discharge electrode, the minority free electron in air by electric field acceleration, and
The fierce collision of gas molecule, forms ionization by collision, not exclusively electric discharge --- corona discharge occurs.So it is full of near corona discharge electrode
Electronegative particle, during well-regulated motion process is made under electric field action, is attached to above during the particulate for meeting neutrality, makes micro-
Grain is negatively charged, and the process is electric-field charge, and electric-field charge works mainly for more than 1 μm particulate.Ion is not only in electric field
The lower motion of effect, and also warm-up movement, ion is attached to particulate and makes charge particles during warm-up movement, that is, spread lotus
Electricity.Below 1 μm of particle diameter, particularly 0.2 μm particles below, diffusional charging plays a major role.But between minuteness particle by
Mutual collision opportunity increases after charged, enables these minuteness particles easily big particle of the aggegation to maximum 50 μm of degree.
According to electrostatic theory, the maximum carrying capacity of particulate is in electrostatic field：
E1 in formula --- ionization pole space electrical field, V/cm；The number of n --- electric charge；E --- unit carrying capacity, 1.6
×10-19C；Dp --- mean particle dia, cm；K --- coefficient, k=3 ε/(ε+2)；The dielectric constant of ε --- particulate, averagely can use 2
～3.
Charge particle in field regime is subject to the repulsion of negative plate, the i.e. effect of electrostatic force and sinks on ground connection pole plate
Accumulate.Suffered electrostatic force is：
Fe=QE2=neE2
Fe in formula --- electrostatic force；Q --- particulate institute carried charge, C；E2--- the electric-field intensity of particulate present position, V/
m。
In small particles Reynolds number (Rep<1) resistance that spherical particle is subject in the gas flow is：
FD=3 π μ dpu
When the resistance and electrostatic dynamic balance, slip amendment is considered further that, particulate movement velocity ue in the electric field is obtained,
Also referred to as separating rate or migration velocity：
As can be seen that for set Particle Swarm, when other conditions are constant, u and n/dp are directly proportional.For less than 1 μm
Particulate, because n/dp is stable, so ue also tends to stable, no longer reduce；And if notice with the reduction of particle diameter,
Cunningham modifying factors C will become greatly, then separating rate will also add larger.And the electric-field intensity in whole space, directly
The carrying capacity and its suffered electric field force in field regime of particulate are determined, stronger electrostatic field, the drive that can make particulate is entered
Speed is bigger, conversely means under conditions of equal wind speed, stronger electrostatic field, to by the air particles of whole system
Thing purification efficiency is higher.
The present invention, as radial-flow type dust collecting pole plate, is greatly connect using the activated carbon for having good ventilation structure using activated carbon
Tactile surface, obtains the appearance dirt area much larger than conventional board-like collection electrode.Into the Charge particle of activated carbon passage, due to activity
Charcoal is in itself conductor of good performance, is had in the presence of conductor around the electric charge q of charged particle, will led under the electric field action of q
Body surface produces charge inducing on face, and the power line part sent from q terminates at these induction points.Deposit between electric charge and conductor
In a kind of electrostatic force of similar Coulomb force, also referred to as image force.Lighter charged particle is normal in close conductor or dielectric
When counting higher big object, will be acted on by image force and be attracted and adsorb on the surface of conductor or high-k object.
Therefore, the charged particle in activated carbon vent passages is absorbed into activated carbon contact surface.After absorption, due to speeding in advance
Effect, the absorption that image force is produced can die down.If charged particle insulating properties is good, adsorption time can be longer；If powered
Particulate and absorption wall all have electric conductivity, can lose Coulomb force because of electric charge release；If had between charged particle and absorption wall
It is fully contacted and produces and contact powered, while and have big van der Waals interaction, absorption can be made more firm.Activated carbon is contacted
The extremely rough state in surface itself, therefore after charged particle is once adsorb, because van der Waals interaction will be difficult to certainly
So it is desorbed.In activated carbon vent passages, when external electrical field is not present, space charge density is bigger in charged particle, and it is produced
Raw adhesive force is bigger.
So, electrostatic precipitator is more suitable for trapping minuteness particle, is particularly suited in indoor air environment to inhalable
The removal of grain thing PM10 and PM2.5.
The present invention is discharged using negative high voltage, and near discharge plate 122, a small amount of charged particle present in air obtains foot
Be accelerated to very high speed after enough energy, the electronics of high speed with gas molecule when colliding, by molecule outside track
Electronic impact out, and form free electron and cation.These electronics are again accelerated in subsequent process and collide, due to
Repeated chain process and produce substantial amounts of electronics and cation, be ionized gas, this process is referred to as avalanche effect.
O in this whole process, in air2、H2O etc. is ionized, and produces and have in a large number the very active particles of extensive chemical, such as OH,
HO2·、O·、O3、O2·。
e+O2→2O·
O·+O2+M→O3+M
4e+2H2O+O2→4HO·
And the pollutant in air includes that formaldehyde, toluene, dimethylbenzene etc. also partly can be degraded by high energy electron ionization.Corona
The average energy of electronics is distributed in 0～20eV scopes in electric discharge, therefore when the electronics and VOCs gas molecules of corona discharge generation
During direct collision, its internal chemical bond fission or homolysis can be made and free radical is dissociated into.C h bond by taking toluene as an example, on methyl
Bond energy very low (3.5eV), it is easy to occur dissociation reaction；The bond energy of the C-C between methyl and phenyl ring is 3.8eV, is also easily sent out
Raw dissociation reaction；C h bond on phenyl ring can be higher, 4.6eV, reacts more difficult carrying out；C-C bond energys on phenyl ring are about 5.4eV, reason
By can interrupt for upper, but (closed with big two bonds between carbon atom, existed between adjacent carbon atom because the structure of phenyl ring is relatively stable
The conjugate relation of complexity), the directly effect by electronics is difficult to make its open loop, and mainly by entering again between the free radical of formation
Row reaction, to reach open loop, until last degraded.Mainly include being reacted with O, OH, it is anti-between OH and toluene molecule
The double bond that phenyl ring should before this be made is opened, and inserts oxygen atom, further oxidative degradation.The reaction that electronics direct collision may occur
It is as follows：
C6H5·CH3+e→C6H5·CH2·+H·
C6H5·CH3+e→C6H5·+CH3·
C6H5·CH3+e→C6H4·CH3·+H·
C6H5·CH3+e→C3H4·CH3+H·
C6H5·CH3+e→C3H4·+C4H3·
The collision of electronics and organic matter is one of important channel that organic matter forms free radical, and the free radical that may relate to is anti-
Should be as follows：
C6H5·CH3+O·→C6H5·CH2O+H·
C6H5·CH3+O3→C6H5·CHO2+H2O
C6H5·CH3+OH·→C6H5·H2C·+H2O
C6H5·CH3+OH·→C6H5·CH3·OH
C6H5·+H·→C4H6
CH3·+H·→CH4
C6H5·H2C·+HO2·→C6H5·CHO+H2O
C6H5·CHO+O·→C6H5·COOH
The C obtained by any of the above mode6H5X can further in free radical O, OH, HO of strong oxidizing property2·
In the presence of aoxidize：
Beyond the region of the reaction is typically without departing from corona scope.And O3The performance in above-mentioned produced active material
Relatively stable, its aerial time of staying is general up to 20min～50min, so O3Can produce in the range of corona
Continue afterwards to be entered inside Microporous Structure of Active Carbon with air-flow.Therefore, appropriate O3 is produced in the electrostatic precipitation stage so as to can be complete
The VOCs that oxidized activated carbon is adsorbed, is to ensure the necessary condition that activated carbon can persistently work.Electron energy is in 2～8.4eV
When, O can be accelerated3Decomposition reaction；When electron energy is more than 8.4eV, be conducive to ozone reaction of formation, it is most in discharge range planted agent
The content of this part electronics may be controlled, the control to yield of ozone is realized, ozone shadow is eliminated while oxidative degradation VOCs
Ring.
The present invention, as collection electrode and VOCs adsorbents, can adopt Alveolate activated carbon or sponge using big carbon content active
Shaped activated carbon or fibrous activated carbon sinter again after similar structures, be the characteristics of the structure with larger draught area,
Activated carbon internal structure macropore is more, and windage is little, and it is not only the end face relative with discharge plate 122 that it adsorbs face of gathering dust, also
Including the wall in duct, activated carbon has great specific surface area, and using activated carbon adsorbent is made, and can effectively adsorb room air
Middle most VOCs.The absorption of the gaseous contaminants such as activated carbon PARA FORMALDEHYDE PRILLS(91,95) meets Freundlich isotherm adsorption models, i.e.,
qe=KfCe 1/n
In formula：Qe is adsorption equilibrium capacity；Ce is equilibrium concentration；Kf and 1/n is Freundlich equation constants, characterizes and inhales
The attached dose of absorption property to adsorbate.
The absorption of the Model surfactant charcoal to VOCs not only occurs on charcoal absorption surface, also occurs in absorption
Portion, equilibrium adsorption capacities are mainly relevant with adsorption equilibrium concentration.Therefore when activated carbon reaches equilibrium concentration to VOCs absorption, no
VOCs in air can be proceeded to absorb, but the state balanced each other in adsorption and desorption.But the VOCs volatilizations of interior
It is continuation, general house decoration or adds after new furniture the volatile organic matter such as indoor formaldehyde, toluene, dimethylbenzene and passing through
Initially after a period of time quick volatilization, the sustainable volatilization of composition of residual 3～5 years, while outdoor air pollution thing also can be
Environment is got in during windowing ventilation.But with continuing for working time, activated carbon can reach all the time adsorption equilibrium, result in the need for
Activated carbon is changed, this is also the core place that the air purifier behaviour of activated carbon types all the time denounces.In electrostatic precipitation
During, it is the material with strong oxidizing property that negative high voltage electric discharge causes the accessory substance ozone of air ionization, while being also that air is dirty
One kind of dye thing.Activated carbon sheet due to its huge surface area, and because preparation technology causes activated carbon surface to there are freedom
Base, oxygen-containing functional group, and its Electronic Performance is excellent, therefore itself has catalytic performance.When gas ozoniferous is through living
During property charcoal, ozone can be decomposed by activated carbon catalysis.Activated carbon can cause the enrichment of the two to the strong adsorption of VOCs and ozone,
Also increase the contact probability of ozone and VOCs in whole system simultaneously.Therefore, with activated carbon as reaction media, can be catalyzed
Ozone decomposes rapidly.The oxygen radical produced during ozone decomposed will carry out oxidative degradation to neighbouring VOCs, in ozone
VOCs is finally removed under lasting oxidation, makes activated carbon recover the adsorption capacity to VOCs.
HCOH+O·→HCOOH
