Because titanium dioxide generates the rear existing nontoxic material of organic substance reaction in hydroxyl free radical and the air under UV-irradiation, the hydroxyl free radical that titanium dioxide produces can destroy the energy key of organic gas molecule, make organic gas become single gas molecule, accelerate the decomposition of organic substance, gas, reach the effect of deodorizing, improve air cleaning efficient, under the irradiation of ultraviolet light, the photocatalyst of titanium dioxide coating can be brought into play effect, and it is extremely convenient to use.Photocatalyst is under the irradiation of ultraviolet light, can produce similar photosynthetic light-catalyzed reaction, produce oxidability extremely strong free hydroxy and active oxygen, has very strong photoredox function, the various organic compounds of oxidable decomposition and part inorganic matter, titanium dioxide has destroyed the performance antibacterial actions such as the coenzyme such as intracellular coacetylase and respiration enzyme the breeding of bacterium or fungi is ended by this oxidability aspect sterilization, and powerful energy decomposing organic pollutant, organic pollution is resolved into free of contamination water and carbon dioxide, thereby have extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, the function that purifies air.
Existing application photocatalyst technology carries out the example of air cleaning and killing pathogenic bacteria in the existing air cleaning unit, as shown in Figure 1, be double-deck photocatalyst coating filter structure schematic diagram, on the side to light of two photocatalyst base materials 5, evenly be coated with photocatalyst coating 6, the irradiation of the uviol lamp 7 by 5 of two photocatalyst base materials, photocatalyst coating 6 produces light-catalyzed reaction, when air passes through photocatalyst base material 5, to airborne harmful substance such as formaldehyde, benzene, ammonia, sulfur dioxide, carbon monoxide, the harmful organic substance that nitrogen oxide etc. affect human body health plays catharsis, and to airborne Escherichia coli, staphylococcus aureus etc. have biocidal efficacies.Yet this type of air cleaning unit can't carry out shape adjustments according to the air cleaning passage, and has complex structure, install, safeguard inconvenience, price is higher, and ultraviolet-resistant capacity is poor, the weak points such as service life is short, thus clean-up effect is undesirable, can't satisfy the demand of purification industry.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of photocatalyst coating screen pack is provided, strong adaptability not only, high-efficiency environment friendly, can carry out shape adjustments according to the air cleaning passage, and simple in structure, installation, easy to maintenance, operating cost is low, long service life.
Design for achieving the above object a kind of photocatalyst coating screen pack, comprise the photocatalyst coating material and contain the frame base material, described photocatalyst coating material is the photocatalyst of titanium dioxide material, the described frame base material that contains comprises photocatalyst filtering net base material and filter screen housing base material, described photocatalyst filtering net base material is fixed in by filter screen housing base material and purifies in the pipeline, the air inlet place is equipped with ultraviolet light source in the described purification pipeline, and described photocatalyst coating material is coated the photocatalyst filtering net substrate surface and towards the ultraviolet light source side.
Described photocatalyst coating scantling grade arrives 10nm at 2nm.
The material of described photocatalyst filtering net base material is plastics, polyurethane, metal, papery or pottery.
Described photocatalyst filtering net base material is circle, triangle, square or star.
The filtration aspect of described photocatalyst filtering net base material is honeycomb or latticed.
The material of described filter screen housing base material is plastics, wooden, metal, papery or pottery.
Described filter screen housing base material is circle, triangle, square or star.
Described light touches the coal coating material and contains adhesive.
The utility model is compared with prior art, novel structure, simple, because containing the frame base material comprises photocatalyst filtering net base material and filter screen housing base material, and the photocatalyst filtering net base material is fixed in by filter screen housing base material and purifies in the pipeline, thereby can carry out shape adjustments according to the air cleaning passage, extremely well-adapted uses also very flexible, convenient; And, owing to adopting the photocatalyst of titanium dioxide material as scavenging material, when the air process is coated with the photocatalyst filtering net base material of photocatalyst of titanium dioxide material, through after the filtration of this photocatalyst of titanium dioxide material, can play to air the functions such as sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, purification, the airborne toxic and harmful of effectively having degraded, good purification; In addition, photocatalyst coating screen pack operating cost described in the utility model is low, installation, easy to maintenance, and high-efficiency environment friendly, long service life is worthy of popularization.
