Referring to Figure 15-Figure 18, have the air processor of tubular wine wheel of the present invention, comprise the housing 29 and tubular wine wheel 1 that constitute by spiral case 23 and snail tongue 24; Its tubular wine wheel 1 is rotatably connected in the housing 29 through motor 25, and housing 29 tops are provided with suction port 26, and filter screen 21 is installed on the suction port 26; Be used to remove and bigger small of blocking diameter, such as: hair, soft flocks, ball top, fiber or chip or the like, conventional filtration net 21 resistances are very little; Pressure drop probably has only the 2-3 handkerchief; Can ignore, housing 29 bottoms are provided with the outlet passageway 30 that is communicated with air outlet 28, and snail tongue 24 is positioned at a side of outlet passageway; The motor shaft 27 of motor 25 is rotationally connected with the axle sleeve 3 of tubular wine wheel 1; The axle 2 of tubular wine wheel 1 is rotatably connected on the inwall of housing 29, and in order to improve dust removing effects, air processor also comprises the anion emission ionizer 18 (or corona discharge assembly) of the molecule charging that can make in the air-flow; It is connected with high-voltage power 9, is used for making the molecule of air-flow electronegative before getting into the dedusting passage.
Wherein, anion emission ionizer 18 comprises the secondary transmitter 20 of negative ion master transmitter 19 and positive ion, and negative ion master transmitter 19 is connected in the negative potential of high-voltage power 9, secondary transmitter 20 ground connection of positive ion; Negative ion master transmitter 19 is terminal sharp-pointed metal object, and its most advanced and sophisticated radius of curvature is less than 0.1 millimeter, and the secondary transmitter of positive ion is the metal object of terminal blunt circle, and its most advanced and sophisticated radius of curvature is generally greater than 1 millimeter.Negative ion master transmitter 19 is launched a large amount of negative ion stream because the tip is sharp; The secondary transmitter 20 of positive ion is launched a spot of positive ion because the tip is more blunt; Even negative ion stream by in the small quantity of positive ions of secondary transmitter 20 emissions of positive ion and after, still residue has a large amount of negative ion stream to be used for making molecule electronegative to the molecule charging.Like this, electronegative molecule is caught by high voltage electric field absorption rapidly in the dedusting passage that gets into the through-flow impeller.Thereby further improved dust removing effects.
Anion emission ionizer 18 (or corona discharge assembly) is arranged between filter screen 21 and the tubular wine wheel 1, and perhaps, anion emission ionizer 18 (or corona discharge assembly) is arranged in the outlet passageway 30, and present embodiment is preferably the former.
High-voltage power 9 is applied with low potential and high petential respectively for the first blade A and the second blade B; Thereby between the first interlaced blade A and the second blade B, formed the HV dedusting passage of charging, this HV dedusting passage can effectively adsorb in the air-flow of the dedusting passage of flowing through molecule.HV dedusting passage is to form having between two walls of dielectrics character; There is electric field in the dielectrics; It is an insulating material that shows durable electric charge; The dielectrics electric charge can be made up of electric charge in surface charge layer, the insulating material or polarization charge, crosses when having high-tension dedusting passage when the air communication that is mingled with molecule, and molecule is adsorbed collection.Simultaneously and since the surface coverage of blade the dielectric insulation material layer, even touched can be not dangerous yet for human body, this type of dielectric insulation material layer is owing to have dielectric characteristic simultaneously, still can keep high voltage electric field well and adsorbs molecule.Among the present invention, except with apply the position that current potential is connected, the surface of blade can spray or be coated with the dielectric insulation material layer; This dielectric insulation material layer comprises paper, rubber, resin, polystyrene, polyester; Polyurethane; Organic siliconresin, polycarbonate, dielectric insulation materials such as polyimide alkyd resin, polyethylene, PVC, plastic polymer.
Shown in figure 18; Air-flow and the molecule that is clipped in the air-flow earlier filter out large particle or fiber etc. in the air-flow through the filter screen of the routine that is installed on suction port; Get into the inside of tubular wine wheel 1 then, process then, the HV dedusting passage between the first blade A and the second blade B; HV dedusting passage is caught filtration to the absorption of the molecule in the air-flow, finally discharges from the air outlet through the air-flow of multiple filtration.Spiral case 23 and tubular wine wheel 1 and snail tongue 24 have constituted the free air space of air-flow, and spiral case 23 is used for increasing air quantity and collecting air-flow to tubular wine wheel with snail tongue 24, makes steady air current simultaneously, evenly.When the surface of blade was applied high and low current potential alternately, because the dedusting passage is an arc, the electric field between the dedusting passage was non-linear.Pass charged molecule between the dedusting passage and receive the effect of strong electrical field, deposit by electrophoresis, and uncharged neutral molecule receives the effect of Nonlinear Electric Field, and move, and similar deposition takes place by the dielectrophoresis process.That is: neutral molecule is by the nonlinear interaction of the polar of particulate and strong electrical field and move and deposit.That is to say, in instance of the present invention, chargedly all deposit with molecule neutrality, but the deposition efficiency of charged molecule is greater than the deposition efficiency of neutral molecule, but, the deposition efficiency of neutral molecule also is very significant.Simultaneously; Because air-flow crosses blade path twice; Even the part molecule is not adsorbed deposition when passing for the first time impeller inside, also can when passing blade path the second time, be adsorbed owing to being with electric charge through quilt electrification behind the blade path in the first time by non-linear strong electrical field; Deposit by electrophoresis, therefore improved dust removal efficiency greatly.That is to say that the molecule in the air-flow almost is adsorbed entirely when passing through the blade path with strong electrical field twice.
If the molecule concentration in the air-flow is lower, or needs the space of dedusting less, also can take to reduce the rotating speed of motor 25, perhaps use the short tubular wine wheel 1 of axial length, specifically determine according to use occasion.
Originally the dust removing effects of air processor that has tubular wine wheel can purify about 56 cubic metres space up to more than 99% in half an hour.
It below is an application example.The tubular wine wheel that diameter is 135 millimeters, 200 millimeters of tubular wine wheel axial lengths, blade quantity are 50; Blade adopts the camber blade, and the thickness of individual blade is 1.3 millimeters, and the boss ratio of impeller is 0.75; The curved surface arc length of individual blade is 23 millimeters, and wherein, first blade, second blade all adopt the sheet metal of low internal resistance to make; The coating that insulate in the blade surface spraying then, about 0.05 millimeter of paint thickness, this coating has dielectric characteristic.Central diaphragm adopts the macromolecular material of insulation to make, and is used for support blade, with enhanced rigidity.First blade and second blade are communicated with the conductive hoop that is positioned at left and right sides end plate respectively, conductive hoop separately respectively with the high-voltage end and the low pressure current potential end in contact of high-voltage power.Except that the conductive hoop zone, first blade and second blade are separated through the end plate of processing with the insulation macromolecular material each other, insulate not conducting each other to guarantee first blade and second blade.Before tubular wine wheel does not turn round; The initial concentration of the molecule in the air-flow is 8.2 milligrams/every cubic metre; Give through high-voltage power between first blade and second blade of tubular wine wheel and apply 1.5 ten thousand volts VDC, tubular wine wheel is during with 400 rev/mins rotating speed operation, after 30 minutes; The concentration of molecule is reduced to 0.1 milligram/every cubic metre, and the eliminating rate of molecule is up to 98.78%.And under nature, after 30 minutes, the decay eliminating rate of molecule has only 23%.Dust removal efficiency greatly improves.
