Woven wire in the ozone degradation Catalytic Layer 5 is FeCrAl woven wires；Described nano-oxide catalysis
Agent is the mixture that one kind in Mn, Fe, Ce, Cu or any two kinds and the above mix in any proportion.
The use step of air purifying filter core described in the utility model is：
First, air (dusty gas) passes through first layer, i.e., the primary granule filter layer 1 being made up of synthetic fibers, effectively
Filter out the particulate pollutant that particle size is more than 2.5 microns.
Then, the air by initial filter passes through the second layer, i.e. catalysis oxidation and stenlizing layer 2, its sectional view as shown in Fig. 2
Two outsides of catalysis oxidation and stenlizing layer are porous wire netting, and wire netting area load has Pt-Ag/TiO2Nanocatalyst,
Pt-Ag/TiO2Nanocatalyst PARA FORMALDEHYDE PRILLS(91,95) has very strong room-temperature catalytic oxidation ability, in -20-100 DEG C of temperature ranges
Can be CO Formaldehyde decomposition2And H2O.The centre of catalysis oxidation and stenlizing layer is provided with inverted T-shaped pipe 6, is held in T-shaped pipe 6
There is chlorine dioxide slow-release piece, the upper end tube nozzle of T-shaped pipe 6 is the dog-house 61 of chlorine dioxide slow-release piece, each side there is one
The clean-up port 62 of with closure, for the chlorine dioxide slow-release piece of cleaning failure, after chlorine dioxide slow-release piece and air contact,
Low concentration chlorine dioxide gas can be slowly discharged, so as to reach to the sterilization of whole air purifying filter core, Disinfection Effect.Titanium dioxide
The burst size of chlorine can be controlled by the inventory of chlorine dioxide slow-release piece.
Then, organic gas adsorption layer 3 of the air of chlorine dioxide Jing Guo third layer, organic gas adsorption layer 3 are carried
Including cellular framework, the inner dispersion of organic gas adsorption layer 3 is placed with the absorbent particles of high-specific surface area, the framework
Material for aluminium alloy, polypropylene etc..Described high-specific surface area adsorbent is activated carbon, molecular sieve or porous polymer resin
Material, there can be efficient adsorption capacity to indoor formaldehyde, toluene, dimethylbenzene and ammonia etc..
Then, the 4th layer of high efficiency filter layer (HEPA) 4, high efficiency filter are passed through by the air of adsorbent adsorption cleaning
The material of layer 4 is the glass fiber material high efficiency filter paper folded, can effectively be filtered less than 2.5 micron particles pollutants.
Finally, the air after four purifications essentially eliminates the pollution of organic exhaust gas, solid particle etc., last layer
For the ozone degradation Catalytic Layer 5 of purifying low-concentration ozone.Ozone degradation Catalytic Layer 5 includes FeCrAl woven wires, FeCrAl gold
Category silk screen area load has the composite oxides nanocatalyst to ozone with efficient-decomposition ability, ozone can be thoroughly degraded
For oxygen.
Above-described embodiment is only used for illustrating the inventive concept of patent of the present invention, rather than to the utility model rights protection
Restriction, all changes for carrying out unsubstantiality to the utility model using this design, the protection model of patent of the present invention all should be fallen into
Enclose.
