By reference to the accompanying drawings, present pre-ferred embodiments is described in further details.
As depicted in figs. 1 and 2, first present pre-ferred embodiments is combined into the column of hollow by two panels arc-like sheet 20,21, be provided with air distribution cavity lid 31 and air collecting chamber lid 11 at the two ends of this column, loads onto seal cover 30,10 respectively in both outsides simultaneously.Gas flows into from air distribution cavity lid 31 one end, flows out from air collecting chamber lid 11 one end.
Column in the present invention can adopt single cylindrical structure also can adopt multiple combined-type, is similar in the present embodiment and lifts.Housing can by plastics, and pottery or other synthetic insulating material are made, and shell inner surface have cutting 211, for fixed catalytic electrode array of vanes 23 with to electrode array of vanes 24.
See Fig. 3, inner at hollow column, be coaxially arranged with quartz burner 25.The power connection part of ultraviolet lamp tube is in outside housing.There are two the radial electrode array of vanes that overlap centered by axis of a cylinder in column inside, composition graphs 4 simultaneously.First catalysis electrode array of vanes 23.Another is to electrode array of vanes 24.Two electrod-arrays intert together with one heart, and that is adjacent two panels blade is the blade of different motor.
Composition graphs 5, catalysis electrode array of vanes 23 is made up of independent metal sheet, all has ledge at its two ends, connects locating ring 15 and 33 respectively.Locating ring 15 and 33 is made up of insulating materials such as plastics or potteries, and its inner ring is enclosed within quartz burner 25, and also there is corresponding cutting its outer ring, for the jut at fixed catalytic electrode array of vanes 23 Leaf two ends.Catalysis electrode array of vanes 23 is also connected with the catalysis electrode 32 of ring-type near the ledge of air distribution cavity lid 31 simultaneously.
The blade of catalysis electrode array of vanes 23 can be made up of metallic aluminium, zinc, vanadium, titanium, copper or other metal or alloy.Layer of semiconductor or ceramic catalyst coating 233 is provided with at blade surface.Coating composition can comprise oxide, as titanium dioxide, zinc oxide, tri-iron tetroxide, aluminium oxide etc., or metal, as platinum, gold, copper etc., and above-mentioned several mixture.Coating can by powder coated and sinter, sol-gal process sintering or the method such as autoxidation sintering make.
Electrode array of vanes 24 is made up of independent metal sheet.Also there is ledge at its two ends, are connected and fixed ring 14,34 respectively.Retainer ring 14,34 is made up of the insulating materials such as plastics or pottery, and its inner ring is enclosed within outside the ledge of catalysis electrode array of vanes 23, and its outer ring has corresponding cutting equally, for the fixing jut to electrode array of vanes 24 Leaf two ends.
To electrode array of vanes 24 near air collecting chamber lid 11 ledge also with ring-type electrode 13 is connected.Can be made up of the material such as aluminium or stainless steel electrode array of vanes 24.Surface can apply reflector layer, also can not be coated with and only do any surface finish process, strengthens reflecting power.
As shown in Figure 4, Figure 5, catalysis electrode array of vanes 23 and to contactless between all blades of electrode array of vanes 24, can independently separate.
The air distribution cavity lid 31 of inlet end side in the present embodiment, there is the gas dispersion hole 311 of a circle circumferential arrangement its inside.There is a circular hole 302 at seal cover 30 center outside air distribution cavity lid 31.When changing quartz burner 25, quartz burner 25 can insert by circular hole 302 thus, and power connection part stays the surface of seal cover 30.Seal cover 30 separately there is an air admission hole 301, can be used for connecting outside gas circuit.
The air collecting chamber lid 11 of side, outlet side in the present embodiment, there is a circle gas collection hole 111 its inside.There is the groove 112 of a circle at air collecting chamber lid 11 center, can be used to the bottom of fixing quartz burner 25.Seal cover 10 outside air collecting chamber lid 11 there is a venthole 101, can be used for connecting outside gas circuit.
During real work of the present invention, comprise filter element 1, fan/air pump unit 2, photoelectricity composite catalyzing gas conversion unit/group 3(in whole filtration system and can comprise one or more combination of photoelectricity composite catalyzing gas conversion plant of the present invention in it), and center control/display unit 4, as shown in Figure 6.
Operation principle following (for purification of air), whole system starts, and fan/air pump unit 2 starts, and system sucks air from surrounding environment.Solid dust particle in air, first through filter element 1, is removed by air.Air after purification, is delivered to photoelectricity composite catalyzing gas conversion unit/group 3 through air pump, returns in surrounding environment after purification from photoelectricity composite catalyzing gas conversion unit/group 3.
After system starts, in photoelectricity composite catalyzing gas conversion plant, quartz burner 25 lights startup, simultaneously catalysis electrode 32 and to electrode 13 between apply a quiescent direct current voltage.The magnitude of voltage applied can change according to the different size of the model of specific product.But should be in and not produce within the scope of the safety value of electric discharge.
Because ultraviolet source is enclosed in column cavity, the utilization ratio of luminous energy is higher.Ultraviolet light is through to the multiple reflections on electrode 13 and catalysis electrode 32 surface and scattering, and finally the semiconductor catalyst (as titanium dioxide) of catalyzed dose of coating 233 absorbs.The ultraviolet photon absorbed produces free charge, i.e. electronics and hole in catalyst.
The electronics produced and hole are moved towards each self-corresponding electrode under the effect of electrostatic field.Partial charge with the metallic member arriving catalysis electrode before corresponding charge recombination.Remaining corresponding electric charge, under the effect of electric field, arrives and is gathered in catalyst surface, with the gas molecule generation redox reaction of process.
The voltage direction of conversion electrostatic field can obtain hole (to be oxidized to object) or the electronics (to be reduced to object) of high concentration selectively at catalyst surface.
In general use procedure, gas enters from air admission hole 301, and the dispersion hole 311 in air distribution cavity lid 31 enters catalysis electrode array 23 and to the space between electrod-array 24.And move towards outlet side in this space.In moving process, because suction-operated or direct collision are at catalyst surface., as water vapour, chemical reaction can be there is with the hole of catalyst surface, produce the hydroxyl free radical having oxidability in the material in partial air.Hydroxyl free radical and then react with the organic molecule in contiguous gas, resolves into harmless tasteless carbon dioxide and water the most at last.Air is finally assembled from gas collection hole 111, finally discharges from venthole 101.In use, semiconductor catalyst is lossless.In theory, can unlimitedly use.
Above-described embodiment only illustrates inventive concept of the present invention for explaining, but not the restriction to rights protection of the present invention, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should fall into protection scope of the present invention.
