Detailed description of the invention
Referring to accompanying drawing 1-3, the invention provides a kind of Self inhaling type toroidal cryogenic plasma air circulating purifying device, comprise mounting bracket, be arranged on emitter stage 2 on mounting bracket and receiving pole 3 and supporting control circuit, key is: described receiving pole 3 comprises the wire on the insulated column 5 that is wrapped in mounting bracket, and described emitter stage 2 comprises the endless metal pipe equidistantly arranged with receiving pole 3.During specific design, endless metal pipe is equidistantly arranged in outside wiry.
The structure of mounting bracket comprises two fixed heads 1 be arranged in parallel, the fixed bar 4 being fixedly connected with two fixed heads 1 and is arranged on the insulated column 5 at fixed head 1 center.In order to attractive in appearance, circle is arranged to by fixed head 1.Fixed bar 4 is evenly arranged at least 3 groups along its circular, circumferential between two circular fixed heads 1, to ensure the stability of mounting bracket.Fixed bar 4 is also provided with the draw-in groove 4-1 of fixed transmission pole 2, and during concrete enforcement, fixed bar 4 is connections that metal material facilitates emitter stage 2 and control circuit.The center of insulated column 5 is provided with through hole, is provided with the through wires hole be communicated with through hole at the outer surface of insulated column 5, arranges connecting line and think that the receiving pole 3 of insulated column 5 outer surface be wrapped in mounting bracket is powered in through hole and through wires hole.Have shell 6 in the arranged outside of mounting bracket, shell 6 is spacing between insulated column 5 and base by the connection of insulated column 5 and base.Hole bottom gap between shell 6 and base and shell 6 forms air inlet 6-1.The top of housing 6 is provided with air outlet 6-2.Air outlet 6-2 is made up of the air-out passage of circumference array circumference outside the hollow cylindrical outlet section of housing 6 top center.The cylindricality outlet section tangent plane of the axis of air-out passage and its relevant position is angularly arranged, and is equidistantly provided with ring baffle 6-3 in the outer circumference of cylindricality outlet section.The design of such air-out passage coordinates with ring baffle 6-3, and the air after purification can be made from air outlet 6-2 spiral.
Axis along insulated column 5 is evenly arranged organizes annular groove more, and the quantity of annular groove is greater than quantity wiry.Wire is arranged in annular groove, and additional groove can prevent turn on emitter 2 and receiving pole 3 because moisture is excessive, causes short circuit.
Receiving pole 3 comprises the wire in the annular groove being wrapped in insulated column 5 outer surface in mounting bracket or insulated column 5, and emitter stage 2 comprises the coaxial endless metal pipe arranged with insulated column 5, and the truncation surface of metal tube is circular or polygon.Emitter stage 2 and receiving pole 3 equal with the quantity that receiving pole 3 is arranged on mounting bracket is positioned at the below of corresponding emitter stage 2, and the upper edge of receiving pole 3 is parallel with the lower tangent plane of emitter stage 2 and at a distance of 0-5mm.Vertical range between the inscribe anchor ring of emitter stage 2 and the circumscribed anchor ring of parcel receiving pole 3 is within it 14-24mm.
Referring to accompanying drawing 4, receiving pole 3 is the metal wire that at least 2 strands of wire spiral windings are formed.In metal wire, the diameter of every one metal wire is 0.1-1mm, and pitch is 0.8-1.6mm, and the level interval between wire twisted point is 0.1-0.4mm.Adsorb dust Automatic-falling over the metal lines after arranging like this can make receiving pole 3 power-off, can not stick on metal wire and then affect the clean-up effect of next purification of air.
When specific design is implemented, emitter stage 2 and receiving pole 3 are applied in voltage, under High Pressure, form ion field under control circuit effect, and cause ion wind by electric discharge.Insulated column 5 forms effective purification of air passage of whole device with the space of metal tube in emitter stage 2.When bacterium in air and virus are by effective air oasis, the protein structure on surface is destroyed and eliminate.The organic molecule that formaldehyde etc. are harmful, under the effect of the free radical of high energy electron and strong oxidizing property, resolves into water and carbon dioxide.High voltage electric field between emitter stage 2 and receiving pole 3 makes electric charge on partial air band, at the move under influence of electric field force, and the dust granule in air collides and becomes granule and make particle again charged between emitter stage 2 and receiving pole 3, between two metal tubes of receiving pole 3, so repeatedly and then made on increasing dust granule band electric charge and become more and more less, when charged particle moves near the emitter stage 2 of oppositely charged or receiving pole 3, be launched pole 2 due to electrostatic adsorption or receiving pole 3 adsorbs, thus reach air purification effect.
Above radiation pole 2 and receiving pole 3 are metal material or outer surface is metal coating, can be tungsten, molybdenum, manganese, copper, silver, gold, palladium, platinum, nickel, cobalt, titanium, aluminium, iron or using them as the alloy etc. of principal component.
In above embodiment, it is circular or polygonal metal tube that the structure of emitter stage 2 is not limited to truncation surface, and also can be that the sheet metal of tabular is arranged on mounting bracket with certain angle, also can be that metal folding part is arranged on mounting bracket with certain angle.
In above embodiment, wire can be annular, and also can be other closed ring structure, metal tube only equidistantly need can ensure clean-up effect of the present invention with wire.
