Description
Technical field:
This utility model belongs to technical field of air sterilization and purification, is specifically related to be provided with metal tape--the depurator of plate structure reactor.
Background technology:
Along with the progress of civilization, expanding economy, the earth atmosphere that the mankind depend on for existence pollutes and is exacerbated, and urban air pollution is worsening, and especially room air pollution is more very.Investigation report according to the indoor environment expert: people live in indoor average 90% time, and wherein at least 65% time tides at home.Compatriots' health in its serious threat.Especially it is the darkest that child, anemia of pregnant woman and old man are subjected to the room air pollution murder by poisoning; Child particularly, because its respiratory capacity is higher than adult's 50% in the body weight ratio, the easiest childrens respiratory tract infection and the blood disease of bringing out, immunity reduces.
Air pollution mainly is: the bacterioid of legionella, staphylococcus and mycoplasma and virus thereof; Various types of VOC VOC
SParticulate pollutant with the dust particle of aerosol existence form and radioactive particle and so on.Ben be in recent years SARS, bird flu and various influenza virus infect on a large scale the outburst happen occasionally.Especially current influenza A H1N1 has caused global people's death up to ten thousand.The route of infection of influenza A H1N1 mainly is an air, and infectious pathogen is attached to particle diameter in the air≤5 μ m usually and swims on the microgranule, flows with air and spreads, and infected person is caused a disease because of sucking this air.What for this reason, market was released has Filtration Adsorption type, electronics electrostatic adsorption type, ozonization type, disinfection by ultraviolet light type, photocatalytic air disinfection purification etc. several with reply.
The Filtration Adsorption type is the air disinfection and purification unit that present thumping majority toilet selects for use, and common have high efficiency particle air filter, a FFU.It utilizes the Van der Waals force that exists between body surface, and the suspended particulate contaminants in the absorbed air purifies air.It can only the filtering dust, can not thorough disinfection; Filtration resistance increases and increases with the dust granules thing, and dust containing capacity reduces, and purification efficiency descends thereupon.If untimely cleaning or replacing can cause secondary pollution; Its air drag is big, energy consumption is also big; It is also big certainly to drive fan noise.The electronics electrostatic adsorption type, is separated particulate matter by the effect of Coulomb force by the static discharge of electrode from air-flow, reach the purpose that purifies air.It is effective that it removes dust, but bactericidal effect is poor, can not remove harmful gass such as formaldehyde.The ozonization type is to utilize the unstable characteristic of ozone and strong oxidation sterilizing.Ozone is a kind of strong oxidizer, should not place inflammable, that explosion hazard gases directly contacts arranged, can not control of dust.In a single day ozone leak, and the human respiratory tract is damaged.Microorganisms such as the ultraviolet kill bacteria of disinfection by ultraviolet light type employing wavelength 253.7nm, virus.It is invalid that it removes dust; Ultraviolet belongs to black light, leaks easily, can damage human eye, skin.Light catalytic purifying is photocatalyst TiO
2Under the irradiation of the ultraviolet light of 387.5nm wavelength, make air molecule produce hole with strong oxidability, i.e. surface hydroxylation, direct kill bacteria, decomposing organic matter is CO
2And H
2Nontoxic inorganic matter such as O.Its shortcoming is that light-catalyzed reaction is the restriction that is subjected to intensity of illumination, air mass flow, TiO
2The deactivation phenomenom of self is the basic reason that light catalytic purifying efficient reduces; It need establish Burdick lamp and ballast in addition, and energy consumption is big, and working life is short.And the ultraviolet of illumination leaks the same injury problem that exists human body skin, eyes easily.
In view of the limitation of the single purification of clean unit of above-mentioned toilet, thus two or more unit combination of selecting for use that have form, to compensate its defect.This just makes, and air disinfection and purification cellular construction complexity, volume increase, the cost height, use also inconvenient.Comparatively speaking, just there is not this type of limitation in the single purification of plasma air disinfection purifier; Yet some producer is eager to have a try several years ago, is mostly replaced by electrostatic adsorption type now.
Through investigation and analysis: present most producers are used for the plasma reactor discharge positive pole of air sterillization dare not the reuse tinsel, be because often work less than three, four months with regard to fracture of wire, have no way out and use zigzag and tip-like discharge positive pole instead, it is low to be forced to the plasma density accepting to produce, the fact that side effect such as the ozone that is produced, nitrogen oxide are also many is well imagined so it can only be used for the electronics electrostatic adsorption type.
The non-thermal plasma reactor that existing air disinfection purifier is used is made up of anelectrode, negative electrode plate, insulating support and shell.It is several that the structure of anelectrode mainly contains tinsel, zigzag or prong shape.
All be under room temperature, the atmospheric pressure state for room air, select for use resistance to oxidation fine wire, zigzag or prong shape structure as the discharge anelectrode, select for use the resistance to oxidation metallic plate as negative electrode, when the reactor of the extremely asymmetric discharge electrode of this class is made corona discharge and is produced Athermal plasma and carry out air disinfection and purification, the fine wire corona discharge is even, producing non-thermal plasma bulk concentration height, ought to be a kind of preferential.But the fine wire structure is carried out air disinfection and purification as the plasma reactor of discharge anelectrode, occurs before on the market, but makes no public appearances in present nearly 3 years, is replaced by zigzag or the prong shape structure reactor as the discharge anelectrode.Existing Filtration Adsorption, high-pressure electrostatic, ozone, ultraviolet and TiO
2Air disinfection purifiers such as photocatalysis are all respectively having pluses and minuses aspect sterilizing, decomposition toxic organics and the filtration pellet three, the equal imperfection of sterilizing and purifying air but still is widely adopted in various big hospital, office block, market, place of public amusement.
Trace it to its cause is that present non-thermal plasma reactor design is unreasonable: select for use plasma density that fine wire produces high though constitute the discharge anelectrode of non-thermal plasma reactor, be blown easily.For this reason, the discharge anelectrode selects for use rustless steel to make zigzag or prong shape structure mostly.Though zigzag or prong shape are not easy to be blown, point discharge that they are in forms the discharge multiple abscess, and can see in the darkroom has between anelectrode and the negative electrode that a purplish blue light fine rule about Φ 0.2mm--this is the aerial discharge non-uniform phenomenon.Near plasma density height purplish blue light, airborne oxygen and nitrogen are activated easily, generate unfavorable factors such as ozone and nitrogen oxide; And it is low to leave purplish blue light plasma density slightly at a distance, and the air disinfection and purification effect is just poor.The Disinfection Effect of this class reactor is subjected to the restriction of ozone and nitrous oxides concentration, and this also is that present professional and technical personnel feels a most thorny difficult problem.Also have a major defect be work less than some months, zigzag or prong shape discharge tip are because of the splash effect rust.Because the radius of curvature of anelectrode is big more, discharge inception voltage is high more, and discharge current reduces thereupon, and air disinfection and purification efficient can reduce certainly.This decay is subtle, and the plasma density reduction is not easy to be found by user.Though reactor also in work, performs practically no function.This uses in hospital operating room, serious symptom ward and will cause the failure of operative treatment because of the defective bacteriovirus infection accident that takes place of sterilizing.
For example: the Chinese invention patent application number is 200710038821.4, and denomination of invention " assembly modular type systyle electrostatic field device " description homepage just proposes: " the fine rule defective of broken string has easily greatly influenced the reliability of installing." in the technical scheme of this invention, propose: a kind of assembly modular type systyle electrostatic field device; comprise discharge electrode (discharge electrode is positive pole), dust collector pole (receive electrode and be negative pole) and insulator; discharge electrode and dust collector pole spaced and parallel are arranged; the discharge electrode two ends connect the discharge electrode connector; the bottom of discharge electrode is a zigzag; the top of discharge electrode is tubulose, zigzag discharge electrode and dust collector pole form dust collection section, the dust collector pole two ends connect the dust collector pole connector, and discharge electrode connector and dust collector pole connector are connected on the insulator.
Though the static field device working life in this technical scheme is long, because the zigzag discharge electrode is that guiding discharge is inhomogeneous, the oxygen in the discharge tip surrounding air is activated, and to produce ozone unavoidable; " decay " that be the spine discharge again exists throughout one's life.Just have no way out because of " fracture of wire " exactly and make the electrostatic adsorption type air purifier of prong shape, zigzag electrode into.
For another example: the Chinese invention patent application number is 200610024299.X, state clearly in denomination of invention " ionization type gas purifier " claims: a kind of ionization type gas purifier is individually fixed on the insulation board by the negative electrode of several same length and anode two ends to be formed, and constitutes square type electric field; The anode is here pressed the ranks form and is arranged, and two ends vertically are fixed in respectively on two insulation boards; Anode adopts the strong tinsel of corrosion-resistant toughness, and diameter is 0.05～0.2mm, and negative electrode adopts copper or stainless pipe, diameter 8～30cm.
The anode of the ionization type gas purifier of foregoing invention is to adopt the strong tinsel of corrosion-resistant toughness, the plasma density height that is produced; But the anode two ends vertically are fixed in respectively on two insulation boards, because the micro discharge effect that exists between anode and the insulation board, the anode metal silk some months of only working just are blown, and in fact this scheme does not have practical value.
In the prior art: the basic reason that the anelectrode of plasma reactor selects for use fine wire to be blown easily--the micro discharge effect is not found, and is indeterminate to its reason physically yet, thereby just can not find the technical scheme that solves prevention micro discharge effect yet.Everyly implementing the manufacturer that plasma reactor discharge anelectrode is selected the air disinfection purifier of zigzag or prong shape structure for use, majority was done the plasma reactor of tinsel as anelectrode in the past; And perplexed by air disinfection and purification effect and ozone and nitrous oxides concentration this a pair of contradiction that exceeds standard now.That is to say that sterilizing test scrapes through, and the ozone flavor is dense, wants to meet among the GB/T18883-2002 " IAQ (indoor air quality) standard " about air ozone amount≤0.16mg/m
3Regulation be difficult.
What is more, and simply plasma reactor is also abandoned, and makes the prong shape into, the zigzag electrode is made electronics electrostatic adsorption type depurator, and it can only adsorb dust, and decomposing the toxic organic compound ability is not as good as plasma reactor.Would rather sacrifice the sterilizing and purifying effect, with reliability and the working life that exchanges disinfection purifier for; The scheme of abandoning the fine wire anelectrode and selecting for use zigzag or tip-like discharge electrode to make reactor is a kind of technology prejudice.
Released photocatalysis and the electrostatic precipitation technical scheme that combines for this reason.The applying date: 2008.4.22 for example, application number is 200810060790.7, denomination of invention: the independent claim of " a kind of device of long-acting purifying indoor air combined pollution " is to describe like this: a kind of device of long-acting purifying indoor air combined pollution, comprise shell, it is characterized in that: be provided with blower fan, high-pressure electrostatic discharge electrode, high voltage power supply, collecting plate, dust-collector, dc source, ultraviolet source, photocatalysis plate in the described shell, exempt from the regenerated carbon fibrous layer; The shell front lower ends is provided with air inlet, and the lower end, rear portion is provided with the gas outlet, near the gas outlet blower fan is set in the housing; Be provided with the high-pressure electrostatic discharge electrode, the parallel collecting plate that is provided with near air inlet in the housing with the high-pressure electrostatic discharge electrode; Some groups of photocatalysis plates are set behind the collecting plate, and adjacent photocatalysis plate one end is alternately fixed with the upper and lower plates of shell, and the other end leaves the space; Be provided with ultraviolet between the photocatalysis plate; Be provided with before the blower fan of housing rear portion and exempt from the regenerated carbon fibrous layer; Bottom of device is established dust-collector, dc source, high voltage power supply successively, and wherein dust-collector places in the middle of the collecting plate below, and dc power anode links to each other with the photocatalysis plate, and the high voltage power supply negative pole links to each other with the high-pressure electrostatic discharge electrode.
The advantage of this invention is photocatalysis and electrostatic precipitation complementation, but is provided with ultraviolet source, and ultraviolet discharge lamp damages easily, and ultraviolet is conspicuous to the injury of human body.The ultraviolet source power consumption is also not little, a 60m
3The indoor health ministry that meets about the public place air standards, power needs 160W at least.Besides the sterilization of electrostatic precipitation and decomposing organic matter effect are not as good as plasma air purifier.
Summary of the invention:
This utility model is finished as the problem that new type air sterilization purifies in order to solve plasma and optically catalytic TiO 2 technology, provide in order to solve the deficiencies in the prior art and prejudice especially a kind of corona discharge evenly, produce plasma and free radical intensity height, can efficient kill bacteria, virus, degraded VOC, good reliability, long working life be provided with metal tape--the depurator of plate structure reactor.
Test shows: zigzag or tip-like anelectrode reactor are made corona discharge at top place; And metal tape is to make corona discharge around band.Under equal conditions the uniformity of the plasma of Chan Shenging and concentration are tangible superior than zigzag or tip-like.
Want to realize above-mentioned purpose, key will be found out " basic reason that the plasma reactor anelectrode selects for use fine wire to be blown easily ".Through investigating and analysing: present most technical staff select for use insulant such as plastics, lucite, epoxy resin to fix as support in order to solve the high-tension Insulation Problems of volts up to ten thousand between the plasma reactor positive and negative electrode.What minority was also arranged has added hairspring between insulating support and wire electrode.Studies show that: the insulant that dielectric constant is high is beneficial to the positive and negative electrode of isolating high potential, and deadly defect is to produce the micro discharge phenomenon.Be the highfield that forms around the anelectrode, under the catalytic action of plasma, cause the local micro discharge that produces of anelectrode tinsel and insulant contact area.The material that dielectric constant is high more, its surperficial micro discharge phenomenon are more inevitable.The high energy electron that this micro discharge phenomenon produces plays direct effect to the ionization and the disassociation of insulant and metallic conduction material molecule, and catabolite is their oxide and water--the root place that the discharge anelectrode of Here it is plasma reactor selects for use fine wire to be blown easily.The fine wire structure but is that to make no public appearances be understandable over nearly 3 years as the plasma reactor of discharge anelectrode.
The inventor selects same specification high-voltage pulse power source for use, specially to thread, banded, zigzag and the anodal plasma reactor of making of tip-like discharge in closed chamber simultaneously continuously energising oppose than test day and night detection.Work only fortnight, zigzag and tip-like reactor operating current obviously descend; Fracture of wire appears in six week of fadenreaction device work; Band shape is relatively stable.But all reactor bottoms all flow has expired atrous mucus.All there is the creepage vestige of yellow black on insulant surface between the positive and negative electrode, and the sign that is corroded also appears in the rustless steel positive electrode surface in this district.The phenomenon that reactor took place that has added hairspring between insulating support and tinsel anelectrode is also similar, only having postponed about two, three months than tinsel rupture time of hairspring.This is that otherwise tinsel is broken easily or spring is inoperative because spring does not allow too slightly.Even this spring rustless steel make also be unable to escape because of micro discharge by the misfortune of galvanic corrosion.
In above-mentioned senile experiment, the interaction on this plasma and metal, insulant surface produces the influence of micro discharge, at first makes the fraction plasma because micro discharge pollutes, and has reduced plasma density, and the reactor work efficiency is reduced; While also damages the structure of reactor, has shortened service life.Study the effect of this micro discharge mechanism in plasma reactor, proposing practicable technological improvement new departure is the marrow that this utility model is created.
Another is that high voltage power supply is for the plasma reactor matching problem that is capacitive load.Test shows: under atmospheric pressure want to make reactor to make corona discharge generation high concentration plasma and should possess two conditions to improve its sterilization and purification efficient.At first be that plus high-voltage field only applies energy to airborne electronics, heat, quicken, obtain kinetic energy, make the very little electron temperature of quality up to more than 10,000 degree, and other particle acquisition is extremely low-yield in moment (nS level).Another condition is: extra electric field applies time (uS level) of energy to electronics will be much smaller than the time that does not apply energy to electronics, and the energy that gas is obtained can in time conduct, and prevents to carry out the transition to hot plasma and lower efficiency.This just requires plasma electrical source not only to provide outside the dc high-voltage of 10--20KV, also high dutycycle must be arranged, and it is the high-frequency narrow-pulse current of 120nS at least that the rise time reaches.Consider that simultaneously plasma reactor generally is equivalent to the capacitance of hundreds of to thousands of uuF, the positive and negative electrode long-term work is again unavoidably by accidental short circuit--and all these safeties for plasma electrical source, the harshness of stability requirement are well imagined.In view of turn-on and turn-off time of present semiconductor power switch device is the uS level, adopt conventional method for designing: for example semi-bridge inversion, multi-harmonic-oscillations, intermittent oscillation or voltage multiplying rectifier are difficult to satisfy above-mentioned two conditions.The high pressure resistant high-power switch device of nS level costs an arm and a leg, and working life is short, and design is unpractical on the product for civilian use.
