For the deficiencies in the prior art, present invention solves the technical problem that the purifier being to provide a kind of high-pressure ion electric field, with the problem solving existing ionic decontamination devices ion wind velocity and clean-up effect is limited to sparking and ozone.The present invention utilizes release electrode to repel each other in the same sex to repel thrust produced by ion the ion in air is produced acceleration simultaneously, so that purifier can be accomplished to purify on the premise of promoting without blower fan and can be as the power of depurator.
The corona electrode of above-described embodiment and the passive electrode of dust are the most independent parts, such combination can adjust voltage and distance by corona in the description according to summary above, and the contradiction being accurately controlled a series of interrelated mutually restrictions again such as wind speed, sparking and ozone generation has superior effect.Invention from above illustrates that be perfectly clear sees, the change of any one distance of whole electrode assemblie, ion wind velocity, air quantity, clean-up effect will be affected, in order to reduce excessively complicated debugging efforts, artificial for some mutual relation being fixed, the passive electrode of the present invention and to repel electrode be a molectron, the design of the physical dimension of this combination is the most accurate, and electrode positions each other, draw optimum data by experiment, thus obtain optimal electric field effect.
Being described further the electrode assemblie using recommended technology shown in Fig. 2, a kind of high-pressure ion air cleaner includes thread corona electrode 102, passive electrode, repulsion electrode.Denoting two thread corona electrodes 102 in the sectional view shown in Fig. 2, two thread corona electrodes 102 are positioned in approximately the same plane.The maximum of thread corona electrode 102 quantity not should be greater than the 1/2-1 of ＞ passive electrode quantity, the most no less than passive electrode and minima is 1.Assume that ion air purifier has 16 passive electrodes, then the maximum of corona electrode is 16, and minima is 7=16/2-1.That is distance D1=＞ D2, D1 ＜=2*D2.
A series of passive electrodes that this electrode assemblie also comprises.3 passive electrodes 203 are shown in the cross-sectional view of Fig. 2, passive electrode 203 is that garden cylinder edge (i.e. passive electrode cylinder end face 2032 in Fig. 2) forms with one flat plate shape electrode (i.e. passive electrode electrode slice 2031 in Fig. 2) by side, cylindrical edge side (i.e. passive electrode cylinder end face 2032 in Fig. 2) is towards thread corona electrode 102, the ionization limit of three passive electrodes 203 is positioned in approximately the same plane
This electrode assemblie also comprises a series of repulsion electrode 301.In the cross-sectional view of Fig. 2, show that 2 are repelled electrode 301, repelling electrode 301 is to be connected three cylinders by plate electrode to constitute, three cylinders lay respectively at towards, the most thread corona electrode 101 and centre position, two ionization limits repelling electrode 301 are generally aligned in the same plane, in order to produce high-tension electricity potential difference at depurator during working, this electrode assemblie is also connected electrically to a high voltage power supply 2 producing high-tension electricity potential difference.
The diameter d of passive electrode 203 should be more than the diameter of thread corona electrode 101, and ratio should be more than 50 times.Burst size according to ozone is amassed by discharging surface, and is i2 with the relation of discharge current i, and the burst size of the thinnest ozone of diameter of corona generation polar filament is the fewest, it is contemplated that mechanical strength and electrical effect, and optimal scheme is that corona electrode diameter existsBetween, passive electrode partial cylinder type diameter of section existsBetween.The plane of each passive electrode and corona electrode group is completely vertical, in order to promote air from corona electrode smoothly flow through passive electrode, in Fig. 2, display is from left to right, such as the direction of air-out direction 130 in Fig. 2.Corona occurs the distance between pole (thread corona electrode 101) to be D1, the phenomenon that ionizing radiation interferes as can be seen from Figure 5, it is recommended that preferred plan be 10-12mm.
It is separated from each other between described adjacent passive electrode 203, each passive electrode 203 is parallel to each other, distance between passive electrode sheet 2031 is D2, plan range produced by the plane of described corona electrode silk (thread corona electrode 102) combination generation and tabular passive electrode series is D3, the distance of D3 is to consider electric field intensity, wind speed, sparking and ozone generation, insulant creep age distance, with reference to comprehensive formulations such as UL867 standards.It is known that the generation of ozone is proportional to corona current, their relational expression is i2, but unrelated with the discharge voltage of corona or power.For example, assuming that the D3 in an ion air purifier is 30mm, corona current is 0.7mA, and between thread corona electrode 101 and passive electrode 203, electric potential difference is 20KV, and ozone production rate is 10mg per hour, if increasing D3 to 60mm and making electric potential difference become 40KV, corona current is about 0.35mA, then ozone generation rate is about 5mg per hour, it is clear that, from the point of view of reducing ozone, the value of D3 is the bigger the better.Distance D2 between passive electrode should be the least to ensure good dust collection efficiency simultaneously.Entering passive electrode and the region repelled between electrode at charged dust, dust granule is collected electrode adsorption under the effect of high field and electrode of being ostracised repels.If the value of D2 is excessive, the charged dust granular absorption probability on passive electrode surface declines, and therefore D2 should be sufficiently small to ensure good adsorption effect.But D2 can not be the least, the flowing of ion wind otherwise can be affected.Experiment shows, the distance of D2 at 10-15 in preferable distance.
Experiment shows that the optimum operation of this suggested design occurs when when more than 3 times of D3 ＞ D2, i.e. D3 is more than 3*D2, and the optimization of this ion wind air purifier physical model occurs in following size: D3=45-55mm, D2=12-15mm.
The ion wind purifier of this recommendation invention contains repulsion electrode, and Fig. 2 shows that 2 are repelled electrode 301, and these electrodes are between passive electrode 203 and at passive electrode 203 and repel formation high field between electrode 301.
Each repulsion electrode 301 is also completely vertical with the plane of thread corona electrode 101 groups, and it is consistent to the guide effect of air-flow with passive electrode 203.Repel electrode 301 be adjacent between passive electrode 203 and and passive electrode 203 between produce the electrode of electric connection, the distance repelled between electrode slice is D4, because repelling electrode and passive electrode is that center line is installed the most separately so D4=D2, use the process hands section repelling electrode 301 voltage higher than passive electrode 203 voltage, the acceleration of ions passive electrode 203 downstream near repelling electrode 203 is forced to move, the six-ten 1/2nd of D3 is only had owing to repelling physical distance D6 of electrode 301 and passive electrode 203, so in terms of clean-up effect, the power of influence of field intensity occurs extremely to act on passive electrode big many than corona.nullSee Fig. 2，Described repulsion electrode 301 ionizes limit in the same direction have distance D5 (i.e. towards the distance repelled between electrode circle cylindricality end face 302 midpoint and passive electrode cylinder end face 2032 midpoint in corona electrode direction) towards ionization limit and the passive electrode 203 of thread corona electrode 101 one end，The effect of D5 distance can see, from Fig. 4 dust flight path, the interaction repelled between electrode 301 and passive electrode 203，And the effect of split channel，The distance of D5 plays an ion conductance to the effect with shunting，The distance of D5 more little airflow passage is the narrowest，The effect of water conservancy diversion is the least，The distance of D5 is the biggest，Gas channel is the widest，The effect guided is the biggest，Experiment shows the centre-to-centre spacing distance best results of D5=D2，With reference to the direction vector of 3011 air-flows in Fig. 4，It may be seen that the distance of sin30 °=D6/D5=1/2 is optimum distance.
nullCan be seen that the ionization limit that the technical program uses is the curved surface of circular arc from the electrode assemblie schematic diagram 2 using recommended technology，Such as Fig. 2 2032、302、303 electrode assemblies so designed popular flat electrode upper with society now prior art electrostatic air cleaner electrode assemblie as shown in Figure 1 has great difference，From Fig. 3，It may be seen that the safe operating voltage of flat electrode is difficult to surmount 8000V，Otherwise just sparking punctures，Under such voltage，Purification efficiency，Ozone concentration is the most undesirable，But on the right side of Fig. 3，The ionization limit of this suggested design arc-shaped surface substantially increases the running voltage of ion wind air purifier，This suggested design have selected the running voltage of 36000-40000 volt，Under the most superpower running voltage，Granule in air is ionized，This just makes the material in air enter the four states-ionic state of material，Under the most superpower electric field action，The granule being ionized is attracted by electric field，Produce avalanche effect，Or attract、Or clash into the substantial amounts of free radical electron cloud of generation，Thus produce the effect beyond dust adsorption，Its free radical is a kind of strong oxidizer，The materials such as toxic gas are carried out or decomposes，Or the process of synthesis.The safe operating voltage of ion air purifier is greatly improved again due to this suggested design, sparking threshold values increases substantially, great kinetic energy is created between corona electrode and passive electrode, its energy sufficiently achieves and need not blower fan and just can drive air, form the convection current in air, thus play and the dust granule in air is collected depurator.In Fig. 2, air has air intake direction 150 to enter 110 ionized regions, enters dust collecting region 120 after being ionized, and after dust granule 280 is adsorbed, the air of cleaning is sent by air outlet air-flow direction 130.
Therefore the present invention is by above-mentioned supertension ion electrode structure, further increase the adsorption efficiency to granules such as dusts, and the function that pathogenic bacteria killed, suggested design the most provided by the present invention makes depurator can run in the case of Blower-free, Energy Efficiency Ratio is up to 14, it is in current air purifier field, a kind of depurator that Energy Efficiency Ratio is the highest.The present invention provides one to air purification field, and low windage is energy-conservation, high adsorption efficiency, the air filter of sterilization.
In some preferred embodiments, transition region between passive electrode cylinder end face 2032 passive electrode electrode slice 2031 also does transition region in the arc-shaped (i.e. passive electrode cylinder and the faying face 2033 of flat board), can further enhance the adsorpting aggregation effect to dust granule 280.
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.
