Embodiment 1
It refer to shown in Fig. 1, embodiment of the present utility model provides a kind of metal membrane filter net, is installed on air filtration
In device, air filter is provided with air inlet 13 and air outlet 14, and metal membrane filter net includes primary efficient filter screen 10, middle effect
Screen pack 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 that primary efficient filter screen 10 is arranged on into air inlet 13 under normal circumstances 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 its efficiency filtered and rank are higher, can be to trickleer
Grain is filtered.
Medium air filtration net 11 is relative to high efficiency particulate air 12 closer to air inlet 13, and the filtering of medium air filtration net 11 is efficient
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 layers of 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,
It 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.Filter plate 15 is cleaned repeatedly, it is lifelong to recycle.
It 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：
Rank F7 is filtered, corresponding to particle diameter >=1.0 μm, ＞ E >=70% of filter efficiency 99%.
Rank F8 is filtered, corresponding to particle diameter >=1.0 μm, ＞ E >=75% of filter efficiency 90%.
Rank F9 is filtered, corresponding to particle diameter >=1.0 μm, ＞ E >=90% of filter efficiency 99%.
It for above-mentioned three kinds filtering ranks, can selectively set, reasonable installation is carried out for different use occasions, it is right
In the higher occasion of filtering requirement accordingly using the high medium air filtration net 11 of filtering rank.
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, the method screened out step by step is used equivalent to air, because PM2.5 particle diameter is different in air, the screen pack in same aperture
The effect for the screen pack that effect is often gradually reduced not as this aperture is good.
It 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：
Rank H10 is filtered, corresponding to particle diameter >=0.5 μm, ＞ E >=95% of filter efficiency 99%.
Rank H11 is filtered, corresponding to particle diameter >=0.5 μm, ＞ E >=99% of filter efficiency 99.9%.
Rank H12 is filtered, corresponding to particle diameter >=0.5 μm, filter efficiency E >=99.9%.
Rank H13 is filtered, corresponding to particle diameter >=0.5 μm, filter efficiency E >=99.99%.
For above-mentioned four kinds filtering ranks, it equally can selectively set, rationally be pacified for different use occasions
Dress, for the higher occasion of filtering requirement accordingly using the high high efficiency particulate air 12 of filtering rank.
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, uses the method screened out step by step, because air equivalent to air
Middle PM2.5 particle diameter is different, and the screen pack effect in same aperture is often not so good as the effect for the screen pack that this aperture is gradually reduced
It is good, and can be influenceed in the particulate for reaching the aperture of high efficiency particulate air 12 by Van der Waals force, different apertures can avoid model
De Huali influence and particulate is trapped in filter bores 16.
It 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.
Further, since the descending setting in the aperture of filter bores 16, and the filtering between adjacent two filter plates 15
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.
It 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 air cleaning in daily life, can be used for industrial dustless factory
In room, or dustless Medical Treatment Room, it can play good Air purification.
