Embodiment 1
Refer to shown in Fig. 1, The embodiment provides a kind of metal membrane filter net, be installed on air filter
Interior, air filter is provided with air inlet 13 and air outlet 14, and metal membrane filter net includes primary efficient filter screen 10, medium air filtration
Net 11 and high efficiency particulate air 12.
Primary efficient filter screen 10 can filter macroscopic large granular impurity, and barrier, primary efficient filter screen are filtered as first road
10 aperture is comparatively bigger, and the filtering rank of primary efficient filter screen 10 is G1-G4, and primary efficient filter screen 10 is relative to medium air filtration
Net 11 is under normal circumstances that primary efficient filter screen 10 is arranged on into air inlet 13 closer to air inlet 13.
Medium air filtration net 11 and high efficiency particulate air 12 can filter the molecule in the air such as PM2.5, and difference is,
High efficiency particulate air 12 is for medium air filtration net 11, and the efficiency and rank of its filtering are higher, can be to trickleer
Grain is filtered.
, relative to high efficiency particulate air 12 closer to air inlet 13, the filtering of medium air filtration net 11 is efficient for medium air filtration net 11
Before screen pack 12, for air-flow direction, medium air filtration net 11 is located at the upstream of air-flow direction, high efficiency filter
Net 12 is located at the downstream of air-flow direction.
Medium air filtration net 11 and high efficiency particulate air 12 include multilayer filter plate 15, and the filter plate 15 of multilayer can effectively strengthen
Filter effect.
It is not laminating between adjacent two-layer filter plate 15 but with certain gap, bypasses air through multilayer filter plate 15
When, equivalent to by filtering in layer, that is, by filtering several times, the speed of air flow can be reduced.
Filter plate 15 offers multiple filter bores 16, and multiple filter bores 16 are covered with filter plate 15, can use matrix arrangement,
Can be arranged using other modes.
Filter plate 15 is made of intermetallic compound, and intermetallic compound here is metal and the composition of ceramics,
Can be metal and metal, or metal and other nonmetallic compositions.The filter plate 15 being made of intermetallic compound is prevented
Rust, anti-corrosion, safety and environmental protection.Allow that filter plate 15 is cleaned repeatedly, it is lifelong to recycle.
Refer to shown in Fig. 2, in the present embodiment, the filtering rank of medium air filtration net 11 is F7-F9, specific filtration grade
It is not as follows：
Filtering rank F7, corresponding to particle diameter >=1.0 μm, ＞ E >=70% of filter efficiency 99%.
Filtering rank F8, corresponding to particle diameter >=1.0 μm, ＞ E >=75% of filter efficiency 90%.
Filtering rank F9, corresponding to particle diameter >=1.0 μm, ＞ E >=90% of filter efficiency 99%.
For above-mentioned three kinds filtering ranks, can selectively set, reasonable installation is carried out for different use occasions, it is right
In filtering requirement occasion higher accordingly using the medium air filtration net 11 that filtering rank is high.
It is more than positioned at the aperture of the filter bores 16 of the medium air filtration net 11 of air-flow direction upstream and is located at air flow side
The aperture of the filter bores 16 of medium air filtration net 11 downstream, the aperture of filter bores 16 that is air passes through gradually subtracts
It is small, equivalent to the method to air using screening out step by step, because the particle diameter of PM2.5 is different in air, the screen pack in same aperture
The effect of the screen pack that effect is often gradually reduced not as this aperture is good.
Refer to shown in Fig. 3, in the present embodiment, the filtering rank of high efficiency particulate air 12 is H10-H13, specific filtering
Rank is as follows：
Filtering rank H10, corresponding to particle diameter >=0.5 μm, ＞ E >=95% of filter efficiency 99%.
Filtering rank H11, corresponding to particle diameter >=0.5 μm, ＞ E >=99% of filter efficiency 99.9%.
Filtering rank H12, corresponding to particle diameter >=0.5 μm, filter efficiency E >=99.9%.
Filtering rank H13, corresponding to particle diameter >=0.5 μm, filter efficiency E >=99.99%.
For above-mentioned four kinds filtering ranks, equally can selectively set, rationally be pacified for different use occasions
Dress, the occasion higher for filtering requirement is accordingly using the high efficiency particulate air 12 that filtering rank is high.
It is more than positioned at the aperture of the filter bores 16 of the high efficiency particulate air 12 of air-flow direction upstream and is located at air flow side
The aperture of the filter bores 16 of high efficiency particulate air 12 downstream, equivalent to the method to air using screening out step by step, because air
The particle diameter of middle PM2.5 is different, and the screen pack effect in same aperture is often not so good as the effect of the screen pack that this aperture is gradually reduced
It is good, and can be influenceed by Van der Waals force in the particulate for reaching the aperture of high efficiency particulate air 12, different apertures can avoid model
The influence of De Huali and particulate is trapped in filter bores 16.
Refer to shown in Fig. 4, in the present embodiment, the cross section of filter plate 15 sets waviness, or other
Shape, mainly on the premise of area of section is not changed, increases the draught area of filter plate 15, by increasing capacitance it is possible to increase the ventilation of filter plate 15
Amount, increases the efficiency of filtering.
Filtering between two filter plates 15 further, since the descending setting in the aperture of filter bores 16 and adjacent
Hole 16 is staggered, can make particulate by when the direction of flowing is varied multiple times, increase the efficiency of filtering.
Intermetallic compound belongs to a kind of combined material, and intermetallic compound is the composition of metal and ceramics, metal and
The combination of ceramics can increase the oxidation resistance of filter plate 15, and with waterproof, antirust and anticorrosion neutralization.It is above-mentioned
Intermetallic compound can also be other compositions.
Refer to shown in Fig. 5, metal membrane filter net also includes framework 17, framework 17 includes the first framework 17 and second framework
17, the edge of filter plate 15 is clipped between the first framework 17 and second framework 17.
Metal membrane filter net can apply to the purification of air in daily life, it is also possible to for industrial dustless factory
In room, or dustless Medical Treatment Room, can play good Air purification.
