Description
Technical field:
This utility model belongs to technical field of air sterilization and purification, is specifically related to a kind of plasma air disinfection purifier.
Background technology:
Existing air disinfection purifier divides main six kinds of Filtration Adsorption type, electronics electrostatic adsorption type, energetic ion sterilizing and purifying type, disinfection by ultraviolet light purification type, light catalytic purifying and the plasma disinfection purification types etc. that have by the air sterillization factor pattern; The air disinfection and purification method drives indoor air stream by blower fan and realizes through above-mentioned air disinfection purifier.
Filter-type absorption realizes purifying air with the suspended particulate contaminants in the air flow.Its shortcoming is can only the filtering dust, can not thorough disinfection.If untimely cleaning or replacing filter screen can cause secondary pollution.The electronics electrostatic adsorption type is separated particulate matter by the static 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 efficiently remove harmful gass such as formaldehyde.Energetic ion sterilizing and purifying type utilizes the unstable characteristic of ozone and strong oxidation sterilizing.Ozone can not dedusting.Ultraviolet air disinfection and purification type adopts microorganisms such as ultraviolet kill bacteria, virus.Ultraviolet belongs to black light, leaks easily, can damage human eye, skin; Can not dedusting.The light catalytic purifying technology is photocatalyst TiO
2Under the irradiation of the ultraviolet light of 387.5nm wavelength, TiO
2Be situated between with on electronics be excited into conduction band, produce corresponding hole--free electron kill bacteria, decomposing organic matter are CO
2And H
2Nontoxic inorganic matter such as O.Its shortcoming is TiO
2The deactivation phenomenom of self is the basic reason that light catalytic purifying efficient reduces; Can not dedusting.Because the existence of above-mentioned defective generally adopts two kinds to merge use, structure complicated, effect is unsatisfactory.
Existing plasma air disinfection purifier generally is made up of parts such as reactor, high voltage power supply, fan assembly, control device, air inlet, air outlet, power coupling and shells, air inlet, air outlet are provided with air filter, and plasma reactor is arranged among the air-flow.Plasma reactor mainly is made up of anelectrode, negative electrode and shell.The structure of anelectrode has tinsel, zigzag or prong shape several.The sterilizing and purifying mechanism of plasma air disinfection purification type is: plasma is made up of a large amount of positive and negative charged particles and neutral particle and is shown the gas cloud that collective's electric field action, electric charge integral body are quasi-neutrality.Plasma constitutes serious the puncture and destruction to bacterial cell membrane; Be that it can open the gas molecule key again, generate monoatomic molecules, negative oxygen ion, OH ion and free oxygen atom, H
2O
2Deng free radical, have extremely strong activation and oxidability.It has very strong lethality to antibacterial, virus.Macromolecule toxic organic compounds such as it can also decomposing formaldehyde, benzene, radon, ammonia, carbon monoxide, flue gas, TVOC change into the low nonpoisonous and tasteless inorganic matter of molecule, as charcoal, water etc.Plasma reactor contains electrostatic field, can adsorb for a short time of 0.1um size particles thing, further purifies air.
The advance of plasma air disinfection purification techniques is approved by expert scholar that the science of its sterilizing mechanism and advance are unrivaled, is referred to as in the world one of " 21st century environmental science four big technology ".But it is also rare to apply on the market, makes slow progress.Filtration Adsorption, high-pressure electrostatic and TiO
2Air disinfection purifiers such as photocatalysis still are used in various big hospital, office block, market, place of public amusement; Though ozone, disinfection by ultraviolet light depurator reduce to some extent, yet food factory, pharmaceutical factory and semiconducter IC manufacturing industry are mostly selected the FFU air filter unit for use.Its energy consumption is big, noise is arranged, and the maintenance cost costliness still has the anxiety of secondary pollution, exactly occupies very big market.
One of trace it to its cause is that the reactor design of present plasma air disinfection purifier is unreasonable: select plasma density that fine wire produces height for use though constitute reactor discharge positive pole, 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, but the point discharge state that they are in, the discharge multiple abscess that forms, in the darkroom, can see have between anelectrode and the negative electrode one about Φ 0.2mm purplish blue light fine rule-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 sharp acicular 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; Though also in work, perform practically no function on the reactor surface.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 receives electrode connecting parts, and discharge electrode connector and receipts electrode connecting parts are connected on the insulator.
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.Because the micro discharge effect between anode and the insulation board, the anode metal silk some months of only working just is blown.
Another reason be exactly the power supply that cooperates plasma reactor at present be not very appropriate for the plasma reactor coupling 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 tens thousand of degree, and other particle acquisition is seldom 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 climbing speed reaches.Consider that simultaneously plasma reactor is a capacitive load, 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 to be 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.
For this reason, majority has been selected simple, inexpensive DC high-voltage power supply for use on the market.As everyone knows, the active space of the plasma that dc corona discharge forms is little, only limits near the corona discharge.Know from experience breakdown and the formation spark discharge when DC voltage is higher than reactor positive and negative electrode marginal value seasonal epidemic pathogens, gas temperature is raise, efficient is low, energy consumption is greatly apparent; Also a large amount of ozone can appear.For example adopt the technical scheme of high-voltage alternating rectifying and wave-filtering to belong to DC high-voltage power supply exactly.The producer that has directly selects piezoelectric ceramic transformer for use, its output be several kilovolts high-frequency alternating current, must adopt the voltage multiplying rectifier filter circuit to boost and just can reach the corona discharge requirement, what the result exported also is the high direct voltage electric current.Above-mentioned power supply produces ozone and is inevitable for the sparking that plasma reactor occurred, the arcing that are capacitive load.
By the AC-DC overlaying power of institute of many producers using plasma reactor in the world, high-frequency and high-voltage alternating current of stack is realized on the high voltage direct current basis.It forces down than the corona discharge peak electricity of dc source, and voltage range is wide, but decreases slightly in the burst pulse corona discharge method, so the quantity of active particle and active space all fall between.It neither be ideal as the coupling power supply of plasma reactor.
The anelectrode of prior art ionic medium precursor reactant device select for use fine wire to be blown easily basic reason--the micro discharge effect is not found, thereby also just can not find the technical scheme that solve to stop the micro discharge effect.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.Just have no way out because of " fracture of wire " exactly and make prong shape, the electrostatic adsorption type of zigzag electrode, plasma air disinfection purifier into, would rather sacrifice the sterilizing and purifying effect, with reliability and the working life that exchanges disinfection purifier for, the technical scheme of selecting zigzag or tip-like discharge electrode for use is a kind of prejudice.Add not matching of high-voltage DC power supply, cause present plasma air disinfection purifier poor reliability, short, the sterilizing and purifying inefficiency of working life; Had many this respect paper, patent to deliver in the past, but replaced by the electrostatic adsorption type of prong shape, zigzag electrode, plasma air disinfection purifier in recent years, reason just is this.

This utility model compared with prior art has following beneficial effect:
Designed plasma reactor anelectrode is fixed on by some nickel chromium triangle tinsels or nickel chromium triangle metal tape and stops on the micro discharge conductor rail in a kind of plasma air disinfection purifier of this utility model, away from the insulation junctional complex; Be that the two ends that stop the micro discharge conductor rail are fixed with four anelectrode metal racks that quadrature is arranged on around the reactor again again, and make electric connection.The insulation junctional complex only is that an end face contacts with stoping micro discharge conductor rail surface, so compared with prior art, its micro discharge effect can be ignored substantially.The cross section that is noted that prevention micro discharge conductor rail especially is much bigger compared with nickel filament or nickel chromium triangle metal tape, even there is faint micro discharge effect, also can not influence plasma reactor operate as normal and service life thereof.Like this, make every nickel filament or nickel chromium triangle metal tape in the direct current highfield, make stable corona discharge, obtain the high concentration plasma.Overcome " fine rule is the defective of broken string easily ", corrected and " would rather sacrifice the sterilizing and purifying effect, abandon the anelectrode of fine wire and select for use zigzag discharge electrode or the tip-like ionization utmost point with the reliability that exchanges disinfection purifier for and the technology prejudice of working life." be the cathode conductor connection plasma reactor shell earthing line of external direct current power supply again, effectiveness is good, meets the electromagnetic compatibility requirement.
The upper/lower terminal of the every anelectrode metal rack that this utility model is bright is established an insulation junctional complex and the corresponding installing hole of shell is fixed, and the upper/lower terminal of described negative electrode is to be fixed on the outer casing inner wall, and makes electric connection.Like this, the anelectrode that some nickel filaments or nickel chromium triangle metal tape constitute, stop micro discharge conductor rail and four anelectrode metal racks and plasma reactor shell precision to join together, and insulating properties are good.Because the upper and lower both sides of negative electrode also are to be fixed on the shell, it guarantees that when integral installation anelectrode places adjacent two negative electrode middle part precision height, makes discharge evenly--this is an important indicator of weighing plasma reactor; It is firm that design also makes the overall structure of plasma reactor like this.
Pulse generator outfan in the designed pulse power of this utility model is provided with current detection circuit, detected pulse generator output current signal is sent into agitator, error amplifier and PWM comparator in the digital control circuit, convert the input that exports pulse generator behind the digital control electric current to, with the output pulse width of automatic adjustment pulse generator.Current detection circuit cooperates with the tacit agreement of digital control circuit, obtains the high-frequency narrow-pulse drive current, makes the plasma reactor that is capacitive produce the high concentration plasma, and the discharge current during work is stable.End a1 of the same name, the a2 of the primary coil of described pulse transformer and secondary coil and different name end b1, b2 oppositely are provided with, and pulse generator and pulse transformer are by the setting of inverse-excitation type inverter; Described secondary coil is that to turn to by section be that two line bags are in series at least, the upper end of each line bag respectively is provided with a high pressure fast recovery diode, the positive pole of high pressure fast recovery diode is connected on the end of electronegative potential line bag, and the negative pole of high pressure fast recovery diode is connected on the initiating terminal of high potential line bag.The distribution capacity of the primary coil of design pulse transformer and secondary coil descends by the index multiplying power of segmentation coiling line bag number like this, greatly improves rising, the fall off rate of its voltage pulse output.Voltage pulse output is more stable, can not occur sparking and so on fault in the plasma reactor work that is capacitive.Mandatory declaration be, pulse generator and pulse transformer are pressed the inverse-excitation type inverter and are provided with, it also makes the plasma reactor and the mains isolation that are attached thereto except finishing the task of boosting, its shell is ground connection directly, electromagnetic shielding, security performance are good.

Complement each other between above-mentioned each parts of the present utility model, it is 20 to 100KH that organic connections, the plasma reactor work that makes the pulse power that the present invention designs for it realize that coupling is capacitive produce output pulse frequency
Z, during dutycycle 20%, pulse width 10--2uS, pulse rise time 70--120nS, pulse amplitude 12--18KV
P-P, disinfection factor is the Athermal plasma of high concentration.
The designed pulse power match plasma reactor work of this utility model also has following three advantages:
At first be that corona discharge is even because the anelectrode of reactor is thread or banded; The burst pulse voltage height of the pulse power is not easy to carry out the transition to spark discharge, and available active particle exceeds several magnitude than direct-current discharge method;
Next is in the fast rise electric field of burst pulse forward position, the corona zone is big in the plasma reactor, the electron density of discharge space also increases, and the space charge effect in reactor distributes and is tending towards evenly, thereby active space is also much bigger than AC-DC overlaying power electric discharge;
Be because above-mentioned 2 advantage again, in the plasma reactor of the present utility model electron density big, distribute extensively, the reactor design has bigger space, so allow certain error, qualification rate height when making.
Generally speaking, the utlity model has good reliability, long working life, generation plasma density height, improve air disinfection and purification efficient.Be not difficult to find out that circuit design of the present utility model is simple, and function is complete, delicate structure, with low cost, good with the plasma reactor coupling that is capacitive.
The plasma reactor and the pulse power are two core components of this utility model plasma air disinfection purifier, the positive pole of pulse power outfan and the anelectrode of plasma reactor are made electric connection, the negative pole of pulse power outfan and the negative electrode of plasma reactor are made electric connection, plasma reactor is arranged between the air inlet and blower fan of air disinfection purifier, its external fan assembly carries out air disinfection and purification under control device control.Plasma air disinfection purifier has the broad-spectrum sterilization effect: to staphylococcus aureus, escherichia coli, bacillus subtilis, read viruses such as strain bacterium, mycete and mycoplasma, hepatitis B, influenza in vain killing rate is efficiently all arranged.Have dedusting simultaneously, remove abnormal flavour, the function of organic exhaust gas such as degradation of formaldehyde, smog and TVOC.This utility model adopts a kind of air disinfection and purification method of above-mentioned plasma air disinfection purifier, and pulse power output pulse frequency is 38KH
