See Fig. 5, it is the structural representation of first group of blade 31 and second group of blade 32 in another preferred embodiment of the present invention.First group of blade 31 with high potential adopts highly-resistant material to make, second inner core 12 with second group of blade 32 of electronegative potential adopts low resistivity materials to make, dielectric insulation material layer 10 is had in the surface coverage of second group of blade 32 with electronegative potential, because dielectric insulation material layer 10 both had insulation characterisitic, there is again very strong dielectric properties, therefore, even if human body contacts the surface of second group of blade 32, very low by the electric current of human body, can not unsoundness danger to people.
See Fig. 6, it is the structural representation of first group of blade 31 and second group of blade 32 in further embodiment of this invention.First inner core 11 of first group of blade 31 and the second inner core 12 of second group of blade 32 all adopt highly-resistant material to make, and be coated with dielectric insulation material layer 10 respectively on the surface of first group of blade 31 and second group of blade 32, even if human body contacts blade surface, because the resistance of this dielectric insulation material layer 10 is very large, very low by the electric current of human body, can not unsoundness danger to people.
See Fig. 7, it is the structural representation of first group of blade 31 and second group of blade 32 in the another preferred embodiment of the present invention.First inner core 11 with first group of blade 31 of high potential adopts highly-resistant material to make, and second inner core 12 with second group of blade 32 of electronegative potential adopts low resistivity materials to make; And be all coated with dielectric insulation material layer 10 on the surface of first group of blade 31 and second group of blade 32.Adopt such scheme, when first group of blade 31 with high potential is made for the high internal resistance material with conducting function, like this, even if user has directly touched this first group of blade 31, the voltage that the electric current flowing through human body equals high potential is divided by the high internal resistance of first group of blade 31 and human body internal resistance sum, because the internal resistance of first group of blade 31 is large, therefore be limited in a low value not producing electric shock, be harmless to the health through the electric current of human body, can not danger be had.When second group of blade 32 with electronegative potential be made up of the low internal resistance material with conducting function time, because the current potential on this second group of blade 32 is low, such as this second group of blade 32 ground connection, even if user directly contacts this second group of blade 32, the electric current flowing through human body is also limited in the low value be harmless to the health, can not have danger, therefore, this second group of blade 32 can adopt low internal resistance material.Even if people contacts the surface of first group of blade 31 or second group of blade 32, because the resistance of dielectric insulation material layer 10 is very large, very low by the electric current of human body, can not unsoundness danger to people.
See Fig. 8, it is the structural representation of first group of blade 31 and second group of blade 32 in the another preferred embodiment of the present invention.First inner core 11 of first group of blade 31 and the second inner core 12 of second group of blade 32 all adopt low resistivity materials to make, and the surface of first group of blade 31 and second group of blade 32 is all coated with dielectric insulation material layer 10.When first group of blade 31 and second group of blade 32 be all be made up of the low internal resistance material with conducting function time, namely no matter be first group of blade 31 with high potential, still there is second group of blade 32 of electronegative potential, adopt the manufacture of low internal resistance material all simultaneously, meanwhile, the dielectric insulation material layer 10 with insulation function is had at the surface spraying of first group of blade 31 and second group of blade 32.So, even if user has directly touched arbitrary group of blade, because the surface insulation of first group of blade 31 or second group of blade 32, because dielectric insulation material layer has very high resistance, very low by the electric current of human body, therefore the surface current of first group of blade 31 or second group of blade 32 is all limited in the low value that is harmful to human health, can not have danger.On the other hand, the dielectric insulation material layer on the surface of this first group of blade 31 and second group of blade 32 is dielectric substance, therefore still can ensure to there is high voltage between blade path.
See Fig. 9-Figure 11, for the present invention embodiment illustrated in fig. 4 in the cascade structure schematic diagram of first group of blade 31 and second group of blade 32.Represent that oblique flow wind wheel has arc shaped blade, airfoil blade, dull and stereotyped linear blade respectively, blade is all made up of high internal resistance material.Wherein, blade 3 comprises first group of blade 31 and second group of blade 32, and this first group of blade 31 and second group of interlaced distribution of blade 32, first group of blade 31 has high potential, and second group of blade 32 has electronegative potential.First group of blade 31 and second group of blade 32 mutually insulated, not conducting.
It should be noted that in previous embodiment, high internal resistance material refers to that in unit thickness, film resiativity is the material of 12 power ohm meters of 6 powers to 10 of 10, comprises electroconductive nylon, conduction ABS, conductive silicon rubber, conduction PP or conduction PS, conduction AS etc.Described low internal resistance material refers to that in unit thickness, its film resiativity is less than the material of 1000 ohm meters, comprises carbon back coating, metallic plate, metal film, carbon-based films or ceramal.Described dielectric insulation material layer 10 comprises paper, rubber, resin, coating, polystyrene, polyester, polyurethane, organic siliconresin, polycarbonate, polyimides alkyd resins, polyethylene, polyvinyl chloride or plastic polymer.
In previous embodiment, dedusting passage is formed between two walls with dielectric character, dielectric memory is at electric field, it is the insulating materials of a durable electric charge of display, dielectric charge can be made up of the electric charge in Surface charge layer, insulating materials or polarization charge, like this, when the air-flow being mingled with dust granules is by having high-tension dedusting passage, dust granules is by absorptive collection.
Meanwhile, due to the surface coverage dielectric insulation material layer 10 of blade, even if touch also can not be dangerous for human body, this type of dielectric insulation material layer 10 is owing to having dielectric characteristic simultaneously, still can keep high voltage electric field well and adsorb dust.
Hot end, the cold end of high voltage source 9 are connected with the first conducting ring 7, second conducting ring 8 be arranged on wheel hub 2 by contact slipper 15 etc., and first group of blade 31 and second group of blade 32 are applied with high potential and electronegative potential with being staggered.When wind wheel rotates, air-flow is sucked the dedusting passage between oblique flow wind wheel blade, when dust granules is by dedusting passage, the dust granules (band plus or minus electric charge) of charging and the dust granules of any neutrality all bear highfield, and highfield makes dust granules adsorb and is collected in the surface of blade.
When the surface of oblique flow wind wheel blade applies high potential, electronegative potential with being staggered, because the dedusting passage formed between oblique flow wind wheel blade is arc, linear, the electric field between dedusting passage is nonlinear.Be subject to the effect of highfield through the charged dust granules dedusting passage, deposit by electrophoresis, and uncharged neutral dust granules be subject to the effect of Nonlinear Electric Field, and move by dielectrophoresis process, and similar deposition occurs.That is: neutral dust granules moves by the polarity of particulate and the nonlinear interaction of highfield and deposits.That is, in an embodiment of the present invention, charged all deposits with the dust granules of neutrality, although the deposition efficiency of charged dust particle is greater than the deposition efficiency of neutral dust granules.But the deposition efficiency of neutral dust granules is also very significant.
In order to improve efficiency of dust collection further, also can before air-flow enters oblique flow wind wheel 1, the conventional similar airstrainer as screen window used is set in the front end of air inlet, for removing the dust larger with blocking diameter, such as: hair, soft flocks, ball top, fiber or chip etc., conventional filter screen resistance is very little, and pressure drop probably only has 2-3 handkerchief.
Or, for promoting efficiency of dust collection further, also dust granules in air-flow can be made before entering wind wheel by anion emission ionization device preliminary filling negative electricity, two transmitting terminals of anion emission ionization device are connected to the two ends of DC high voltage, anion emission ionization device comprises the main transmitter of anion and the secondary transmitter of cation, the main transmitter of anion is the metal object with sharp tip, and the radius of curvature at its tip is less than 0.1 millimeter, is connected to high negative potential; The secondary transmitter of cation is the metal object with relatively blunt round end, and the radius of curvature at its tip is generally greater than 1 millimeter, and the secondary transmitter ground connection of cation, namely connects the earth terminal of high voltage source.Like this, the main transmitter of anion due to tip sharper, launch a large amount of anion stream; The secondary transmitter of cation due to tip more blunt, launch a small amount of cation; Even if anion stream is neutralized by a small amount of cation that the secondary transmitter of cation is launched, still residue has a large amount of anion stream for dust granules charging, makes dust granules electronegative.Like this, electronegative dust granules is caught by high voltage electric field absorption rapidly entering in the blade path between oblique flow wind wheel.Thus further improve dust removing effects.
Or, for promoting efficiency of dust collection further, two covers or the oblique flow wind wheel series connection of the present invention of many covers can be adopted to use, that is: form two-stage or multistage dedusting passage.Even if the dust like this in air-flow is not being adsorbed by high voltage electric field by during first order dedusting passage, also can be ionized in high voltage electric field and bring electric charge, then being adsorbed by the second level of rear end or other more multistage having in the follow-up blade path of high voltage electric field.
In addition, according to the needs of use occasion, the dust removing effects of the oblique flow wind wheel 1 in the present invention can also by regulating the potential difference at the two ends of high voltage source, regulating the width of blade of oblique flow wind wheel and realized by the design of different oblique flow wind wheel blade quantity, blade height and blade shape.
When the blade surface of oblique flow wind wheel 1 has been filled dust, oblique flow wind wheel can be removed cleaning, such as scrub with hairbrush, soak with abluent, dry or can continue after drying up to use.The dust of blade surface can also be removed to get off to collect in dust collecting sleeve by design automatic dust removing mechanism.
