The specific embodiment
Specify embodiment below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4:
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the plasma disinfecting-sterilizing device includes discharge body (1) and high-voltage pulse power source (14).Discharge body (1) includes framework (15), medium (2), many ionization modules are leaked in resistance, and ionization module is made of with the polar filament regulation fixing apparatus pole piece (3), polar filament (9); The polar filament regulation fixing apparatus includes upper bracket (5), lower carriage (6), brace (4), screw (11), rivet (12), polar filament regulation cock (7), long spring (8), short spring (10).It is injection molded that upper bracket (5), lower carriage (6) and polar filament regulation cock (7) etc. are the withstand voltage flame retardant plastics of DCPD.Polar filament (9) is the stainless steel silk of alloy composition, diameter is Φ 0.2-0.3m/m, make the Current Control of passing through polar filament (9) at the 5-10 microampere, the polar filament two ends are welded with rivet (12), weld lower carriage (6) one ends earlier, pass long spring (8), put into lower carriage (6), screw in polar filament regulation cock (7) again.Then, the other end of polar filament is passed small garden hole in the upper bracket rivet (12) of burn-oning.The short spring (10) of packing into screws in screw (11), guarantees that polar filament (9) reliably contacts on electric with screw (11).Adjust the tightness of polar filament by regulating polar filament regulation cock (7), guarantee that polar filament is not crooked, promptly guarantee the perpendicularity of relative pole piece (3).The polar filament centrad is to be determined by the centre bore of upper bracket (5) and lower carriage (6), and centre bore to be the mould of plastics precision of upper and lower support guarantee.The cross section be the pole piece (3) of equilateral hexagon by two trapezoidal pressing product closures of three-equilateral after spot welding form, material is aluminium flake (stainless steel substrates), pole piece (3) centre distance is 30m/m, and its spacing is supported by upper bracket (5), lower carriage (6), guarantees that pole piece (3) is indeformable.Be that small-sized mash welder spot welding by special use forms between pole piece (3) and the pole piece (3), adjacent cake welds upper and lower 2 points between pole piece (3).During general assembly, reinstall brace (4), polar filament (9) in each ionization module is interconnected by brace (4), pulsed high voltage generator (14) is anodal to be that first shape weld tabs with the high-voltage line outfan closely links to each other by screw (11) with ionization module, and pulsed high voltage generator negative pole (14) and pole piece (3) join.
The work process of plasma disinfecting-sterilizing device is as follows:
After attaching plug connected the 220V alternating current power supply, polar filament (9) peripheral gas molecular ionization in high-voltage pulse power source (15) the excitation discharge body (1), the electric current of discharge body polar filament (9) is injected in control, make the charged particle of its generation reach some, form the glow corona state, this moment, the gas in the discharge body no longer was original gas but plasma, be one group by electronics, ion, atom, the electric conductor that countless microcosmic particles such as free radical are formed, its electronics, ion all has higher energy and reactivity, under effect of electric field, effect by the fierceness collision between the particle and energy exchange and high energy electron, gas molecule is in excited state, the energy that obtains when gas molecule is during greater than the binding energy of its molecular link, the molecular scission of gas molecule, produce the various active free radical, with its harmful gas, antibacterial, the disassociation of a series of complexity takes place in virus, oxidation reaction, resolve into odorless at last, harmless material, thereby eliminate harmful gas and various abnormal flavour, reach sterilization, the purpose that purifies air.
The measure of degerming is mainly by air filtration in the biomedical clean engineering, but fact proved: when the suitable filter of relative temperature and humidity conditions very easily self-reproduction, breed bacteria! Therefore, high-efficiency dynamic continuous sterilization, sterilization filter are directions in the research department.This plasma ion disinfection bactericidal unit and existing filtering material reconfigure combined effect, form a kind of novel filter, must reach dust cleaning and sterilizing, sterilization is gone to distinguish the flavor of and is waited the optimum efficiency purify air, can be widely used in all kinds of disinfection cabinets, air purifier, the clean place of sterilizing air-conditioning, clean operating room and needing sterilization of central authorities.
