A kind of photocatalysis air-cleaning lamp as shown in Figure 2, including lamp cap 1, lamp holder 2 and lamp body 3, the lamp holder 2 are equipped with Pivot section, the pivot section connect lamp cap 1 and lamp body 3 respectively, and the lamp body 3 includes lampshade and is located in lampshade UVA grades of quartz burners 4, the quartz burner 4 are screw type (S type), and the outer wall of the lampshade is covered with colloidal sol type photocatalyst Layer, the outer wall of the pedestal 2 are uniformly laid with nanoscale negative ion powder.

Embodiment three

A kind of photocatalysis air-cleaning lamp as shown in Figure 3, including lamp cap 1, lamp holder 2 and lamp body 3, the lamp holder 2 are equipped with Pivot section, the pivot section connect lamp cap 1 and lamp body 3 respectively, and the lamp body includes lampshade and is located in lampshade UVA grades of quartz burners 4, the quartz burner 4 are that parallel connection type i.e. two straight tube parallel connection is formed, and the outer wall of the lampshade is covered with The outer wall of colloidal sol type photocatalyst layer, the pedestal 2 is uniformly laid with nanoscale negative ion powder.

The colloidal sol type photocatalyst layer is titanium dioxide layer.The lamp holder 2 uses metal material.

Specifically, intracavitary equipped with thermal insulation layer in the hollow type of the lampshade, the thermal insulation layer is coated on UVA grades of ultraviolet lights The side of fluorescent tube 4.

The working principle of the utility model is as follows:

The utility model utilizes the harmless ultraviolet light wave of UVA grades of fluorescent tubes release, activates the colloidal sol of cover surface Type coating of titanium dioxide decomposes the toxic and harmful gas such as indoor formaldehyde, TVOC, benzene homologues and ammonia, while photosynthetic effect occurs Answer, decompose the oxygen molecule and hydrone in air, generate a large amount of negative oxygen ion and hydroxide ion, using negative oxygen ion and The extremely strong oxidisability of hydroxide ion, decomposing organic compounds and part inorganic compound, ultimately form nontoxic dioxy Change carbon and water, while the negative oxygen ion of photocatalysis generation and hydrogen-oxygen water ion also have the effect of spectrum sterilization；In addition in lamp holder Nanoscale negative ion powder is adhered on surface, discharges a large amount of anion, with particle dust positively charged in air, occurs to neutralize electricity Property sedimentation, realize removal PM2.5, be finally reached the purpose of indoor air purification.

The principle of titanium dioxide resolving harmful gas is as follows:

The forbidden bandwidth of TiO2 is 3.2ev (anatase), when it is (ultraviolet less than or equal to the light of 387.5nm by wavelength Light) irradiation when, the electronics of valence band will obtain the energy of photon and transit to conduction band, formed light induced electron (e-)；And in valence band Then correspondingly form photohole (h+).

If each TiO2 particle approximation of dispersion in the solution is regarded as the photoelectrochemical cell of small-sized short circuit, The light induced electron that photoelectric effect should generate and hole move to the different position in the surface TiO2 respectively under the action of electric field.TiO2 The light induced electron e- on surface is easily captured by oxidizing substances such as oxygen in water, generates superoxide radical O2-；And hole h+ Then the oxidable organic matter for being adsorbed in the surface TiO2 or first be adsorbed on OH- the and H2O molecular oxidation on the surface TiO2 at hydroxyl from By base OH；The oxidability of OH and O2- is extremely strong, can almost make the chemical bond rupture of various organic matters, thus can oxygen Its mineralising is the substances such as inorganic molecules, CO2 and H2O by the organic matter and inorganic pollution for changing the overwhelming majority.Reaction process is such as Under:

TiO2+hv→h++e-h++OH-→·OH h++H2O→·OH+H+e-+O2→·O2-H2O+·O2-→ HO2·+OH-2HO2·+e-+H2O→H2O2+OH-H2O2+e→·OH+OH-H2O2+·O2-→·OH+H+·OH+dye →···→CO2+H2O·O2-+dye→···→CO2+H2O

Certainly can also occur, light induced electron and hole it is compound:

H++e- → thermal energy

It is reacted by mechanism it is found that TiO2 photocatalytic degradation of organic matter, substantially a kind of radical reaction.Hydroxyl radical free radical Be containing a unpaired electron free radical, this make it almost can in water nearly all machine pollutant and most nothing Machine pollutant reaction.It is very fast with the reaction speed of pollutant, and reaction speed is limited only by hydroxyl radical free radical in water Diffusion velocity.The reaction mechanism of hydroxyl radical free radical and pollutant is mainly included in unsaturated double bond, the addition reaction on three keys, Hydrogen replaces and the transfer of electronics.Much studies have shown that hydroxyl radical free radical plays a leading role during photocatalytic degradation.Although The oxidizing potential of superoxide radical, single ground state oxygen and hydrogen peroxide is lower than hydroxyl radical free radical, but they are during degradation Play indispensable role.TiO2 photocatalysis mainly passes through the pollutant reaction in the oxygen radical and water of generation, reaches The purpose of degradation, and finally generate water, carbon dioxide, the nitrogen etc. of environmental sound.TiO2 photocatalysis can generate simultaneously Positively charged hole and the electronics with negative electrical charge, this makes the existing oxidability of catalyst system have reducing power again.

Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects Step is described in detail, it should be understood that being not limited to this foregoing is merely specific embodiment of the utility model Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap Containing being within the protection scope of the utility model.
