Fig. 2 a is the sketch map of three-decker among this utility model embodiment.
Fig. 2 b is the structure enlarged diagram of used two kinds of photocatalyst nets in the three-decker among this utility model embodiment.
Fig. 3 is this utility model embodiment hint effect figure that dissects in kind.
The specific embodiment:
Also in conjunction with the accompanying drawings this utility model is described in further detail below by specific embodiment.
As Fig. 1,2, shown in 3, the photocatalyst air sterillization sterilization machine of present embodiment comprises fuselage 1 and the air inlet of being located on the fuselage 2, air outlet 3, the passage of air flow warp is provided with photocatalyst net 4 or 6 in the fuselage, also be provided with sterilization ultraviolet ray fluorescent tube 5 in fuselage interior, the irradiation area of described sterilization ultraviolet ray fluorescent tube 5 comprises the passage of air flow warp---in this example, the irradiation area of described sterilization ultraviolet ray fluorescent tube 5 comprises the above-mentioned photocatalyst net 4 or 6 of air flow on passage that be arranged at, photocatalyst net 4 or 6 adopts ultraviolet to reply type photocatalyst net, and it reaches peak value in the ultraviolet wave band light absorptive of sterilization usefulness.
The main component of " photocatalyst " is nano level titanium dioxide (Tio2), is activated under its ultraviolet energy effect in sunlight and fluorescent lamp, generates a kind of OH bioactive molecule with powerful oxidizing force on the surface of oneself.The OH bioactive molecule has than the chlorine that is used for disinfectant, chlorous acid, the more powerful oxidative function of ozone, and it makes microorganism lose survival ability by the DNA spiral of destroy microorganisms, avoids it to produce new solid, thereby reaches the effect that suppresses breeding.
Ultraviolet sterilization is to destroy the DNA spiral by the OH bioactive molecule that ultraviolet derives to finish, but result of study in recent years shows that ultraviolet can make microorganism lose activity, but microorganism ultraviolet according to less than the place can recover active.The same OH bioactive molecule that generates by its surface with ultraviolet of photo-catalytic sterilization loses activity microorganism, but there is viewpoint to think, the OH molecule that photocatalyst generates can be further decomposed the cell membrane that is covered by fatty acid of certain micro-organisms, and causes the collapse of microorganism by cell pressure reduction.But death process and the principle of antibacterial are not also understood completely.In any case, the bactericidal action of experimental result proof photocatalyst is very tangible, is worth promotion energetically in practicality.
The photocatalyst net 4 that adopts in the present embodiment or 6 reaches peak value in the 250-260nm light absorptive.Therefore, correspondingly, described ultraviolet wave band should adopt the UV-C wave band.
This utility model uses photocatalyst ceramic honeycomb net and UV-C sterilization etc. simultaneously, can play the effect of double sterilization.The filamentary structure of Nidus Vespae net has the function of superior absorption antibacterial, is coated on the online photocatalyst of Nidus Vespae and generates the OH molecule under ultraviolet irradiation, and the OH molecule makes the antibacterial that is captured lose activity rapidly.
Still see Fig. 1,2,3, drainage screen of the present utility model has triplen, is respectively: the photocatalyst three-dimensional ceramic drainage screen (monolayer) of ground floor---UV-C germicidal lamp---the trilaminar photocatalyst ceramic honeycomb net of photocatalyst ceramic honeycomb net---UV-C germicidal lamp---of the second layer.Three interlayers are every arrangement.
As seen, the photocatalyst net that is adopted in the present embodiment has two types:
The one, be positioned at the photocatalyst Nidus Vespae net of second and third layer, it has filamentary structure.Photocatalyst Nidus Vespae net can be caught antibacterial and microorganism fully effectively.Under the dual function of coated photocatalyst material in drainage screen surface and Burdick lamp, antibacterial and microorganism are killed fully.Photocatalyst ceramic honeycomb net and UV-C sterilization etc. are used simultaneously, can play the effect of double sterilization.The filamentary structure of Nidus Vespae net has the function of superior absorption antibacterial, is coated on the online photocatalyst of Nidus Vespae and generates the OH molecule under ultraviolet irradiation, and the OH molecule makes the antibacterial that is captured lose activity rapidly.
The photocatalyst coating adopts SOLGEL method (sol-gal process) to cover foam ceramic filter comprehensively, be coated on the online photocatalyst of Nidus Vespae and under ultraviolet irradiation, generate the OH molecule, make airborne microorganism, the bacterium that swims, scent molecule etc. fully combine, the degerming power of 100% performance photocatalyst with the OH molecule.
The 2nd, be positioned at the photocatalyst three-dimensional ceramic net of ground floor, it has skeleton shape three dimensional structure.Monolayer photocatalyst three-dimensional ceramic drainage screen has deodorization.The foul smell of the oxidation Decomposition function organifying compound that photocatalyst has decomposes by molecular level.And skeleton shape three dimensional structure has strengthened the surface area of contact, thereby has strengthened the deodorant function.
In order to increase contact surface, in this example every layer photocatalyst net 4 or 6 with the parallel placement of two rows about sterilization ultraviolet ray fluorescent tube 5 is divided into, each a slice about the every row of photocatalyst Nidus Vespae net wherein, totally 4; Each horizontal positioned is two totally 8 about sterilization ultraviolet ray fluorescent tube two rows; Each a slice about photocatalyst 3 dimension foam ceramic filters, totally two.Can also line up many rows if desired.
