The filter of particulate matter.
It certainly, according to demand can also include activated carbon filter layer in filtration material layer 11, peculiar smell, is adsorbed in air to remove
Bacterium, virus etc. or photocatalyst layer to further enhance air purification effect remove the gas pollutant in air
And poisonous and hazardous germ and microorganism.
When using Fiber Materials carry out filtration material layer 11 manufacture when, filtration material layer 11 can by polyester fiber, Fypro,
Polyphenylene sulfide fibre, polytetrafluoroethylene fibre, polyvinyl chloride fibre, polypropylene fibre, cyclization, aromatic polyimide
One of fiber, inclined aramid fibre, melamine fiber, glass fibre, ceramic fibre or metallic fiber are a variety of
It is compounded to form.
Windward side conduct piece and leeward side conduct piece are arranged on fixed frame 12, and windward side conduct piece and leeward side are conductive
It can be clamped or be bolted between part and fixed frame 12.Windward side conduct piece and leeward side conduct piece can select gold
Belong to net 2, conductive fabric, conductive materials that plating is equipped with the plastic wire of conductive layer or other permission gases pass through.Windward side conduct piece
Can be identical or not identical with the material of leeward side conduct piece, windward side conduct piece and leeward side conduct piece on the one hand can be with
Apply constant voltage for the two sides of filtration material layer 11, it on the other hand can be with supplemental filtered air.
Further, in wind speed with 0.06m/s perpendicular to windward side conduct piece, leeward side conduct piece and filter material assembly

Applicant to disclosed in this invention clean air package tested, as shown in table 1 below, experiment used
Air cleaning device assembly in filtration material layer be 200g/m3The acupuncture cotton of specification is (main to become the polypropylene and 7% for being 93%
Polypropylene is fine), conductive layer is 200 mesh stainless steel wire meshes, DC voltage 4000V, from top to bottom for every progress in five minutes
Voltage is not added in data test, "No" expression, and "Yes" indicates that on-load voltage, PM2.5 (preceding) refer to air by air cleaning
PM2.5 numerical value before component, PM2.5 (preceding) refer to air by the PM2.5 numerical value after clean air package, and PM2.5 is poor
Value refers to that the difference of PM2.5 in the air of filtering front and back, every meaning in gauge outfit about PM10 please refer to the reason of the definition to PM2.5
Solution, can obviously observe the promotion of filter efficiency from table 1.
1 clean air package on-load voltage of table is compared with the clean-up effect for being not powered on pressure
In above table, the numerical value unit of PM2.5 and PM10 are microgram/m3, when not applying DC voltage, air
Purification assembly between 75%-89%, to the filter efficiency of PM10 between 84%-91%, and adds the filter efficiency of PM2.5
After carrying DC voltage, clean air package between 98.2%-98.7%, imitates the filter efficiency of PM2.5 to the filtering of PM10
Rate is between 98.7%-98.9%, by upper table this it appears that loading clean air package clean-up effect after DC voltage
It is promoted.
In addition to this, a kind of air cleaning facility is also disclosed in the present invention, which includes but is not limited to
Air purifier, new blower etc., the air cleaning facility include the clean air package of shell and setting inside the shell, and empty
Gas purification assembly is the clean air package disclosed in above-mentioned any one embodiment.
Due to using above-mentioned clean air package, it is corresponding which has both above-mentioned clean air package
Technological merit, this is no longer repeated herein.
A kind of air purification method is also disclosed in the embodiment of the present invention simultaneously, this method is for filtering the air
Filter material assembly two sides apply voltage so that DC electric field in the filter material assembly filter material generate polarization, enhance institute
Filter material is stated to the adsorption capacity of particulate matter.
After applying voltage, the both ends of filter material assembly will form DC electric field, and electric field can generate the filter material in filter material assembly
Polarization, polarization will form electric dipole moment, and this polarization will greatly enhance absorption of the filter material to haze particle
Effect, cooperates the filter effect of filter material itself, and air purification ability will be significantly improved.Under same intake resistance, the sky
Gas purification assembly has higher particulate matter filter efficiency, under same filter efficiency, the ventilation resistance of the clean air package
Smaller, power consumption is smaller, obtains higher CADR value.
Same reason, in the air purification method, the voltage of filter material assembly two sides can be that DC voltage can also be
Alternating voltage, and voltage can be higher in order to apply for constant pressure is also possible at any time and changed voltage
Voltage value simultaneously guarantees there is ideal effect, recommends to use DC constant voltage in the embodiment of the present invention.It is further preferred that filter material is total
It is less than the breakdown voltage of filter material assembly, the ozone being detrimental to health to avoid generation at the voltage that both ends are applied.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
