2coating.
The principle of above-mentioned photocatalyst purification is the ultraviolet light utilizing wavelength to be greater than 380nm, is radiated at photocatalyst TiO
2in coating, then with the oxygen (O in air
2) and water (H
2o) reaction is produced, at Surface Creation OH
-and O
-ion, these ions have redox function, can remove the pernicious gases such as formaldehyde, as shown in Figure 3.This reaction of the present embodiment is produced by photocatalyst quartz glass plate 3, so how increasing photocatalyst area and allowing ultraviolet light effectively impinge upon its surface is the key factor affecting photocatalyst purifying formaldehyde device; General air photocatalyst purifier, all from then on important parameter does not go to design and develop effective product, so for indoor except pernicious gases such as formaldehyde, poor effect, even invalid, and power consumption power consumption.
The utility model utilizes quartz glass to penetrate more than 95% to ultraviolet light, and photocatalyst is coated on quartz glass, transparently to penetrate, so utilize quartz glass to do optical catalyst carrier and the compact characteristic of ultraviolet light, in minimum space (such as 20 × 20 × 10 cubic centimeters), create the effect of 1000 times of photocatalyst decomposing formaldehyde effective areas; Therefore transparent photo-catalytic is coated respectively on quartz glass thin slice two surface, at this moment its effect is equal to the quartz plate photocatalyst area effect of 2 times, because ultraviolet light can penetrate and not lose, if we lay out ten with interval mode, then area adds 20 times, as shown in Figure 4.
Another key factor of photocatalyst effecting reaction is the intensity of effective ultraviolet lighting at photocatalyst coating; The intensity that light impinges upon body surface except input power and light source output intensity be except key factor, the distance on light source and illuminated object surface and light and photographed object surface incident angle affect the whether effective key factor of photocatalyst reaction especially; Light arrives square being inversely proportional to of the intensity of body surface and light source and object distance, so the distance of LED light source and photocatalyst coating being reduced is our emphasis, and adopt rough metal surface to increase the scattering of light in clarifier interior surface, allow ultraviolet light can be full of whole clarifier inner, fully can clash into photocatalyst coating; The active strength that general light impinges upon body surface is I (the θ)=I calculated with physical quantity below
0cOS θ, by the object of high scattering metal surface, allows all light can meet angle θ exactly and goes to zero, reach I (θ)=I
0cOS θ ≈ I
0, reach maximum effect of light strength.
Operation principle of the present utility model is: outside air is pumped in housing 1 by extraction fan 2 by air inlet, air in housing 1 flow between each photocatalyst quartz glass plate 3 respectively, simultaneously LED 4 be radiated at photocatalyst quartz glass plate positive and negative on, be radiated at photocatalyst TiO
2in coating, then with the oxygen (O in air
2) and water (H
2o) reaction is produced, at Surface Creation OH
-and O
-ion, these ions have redox function, and these reacted ions spill out in the air outlet 101 housing 1 with air, and the ionic air flowed out can remove the pernicious gases such as formaldehyde.
Embodiment 2: the modular construction included by the present embodiment and the position relationship between each parts substantially the same manner as Example 1, difference is that the photocatalyst reflecting piece group that is made up of photocatalyst reflecting piece is to replace photocatalyst quartz glass plate group, photocatalyst reflecting piece does not have the transmittance of light but has reflectivity, scattering can be carried out by between ultraviolet light and the inwall of housing, clean-up effect is worse than embodiment 1, and the spacing between each photocatalyst reflecting piece of photocatalyst reflecting piece group is at 2 cm.
The utility model reasonable in design, simply, good looking appearance, utility function is strong, can be applicable to average family, office space, public place use.
