6- end face seal components, 7- edge seal members.
Specific implementation mode
Air purifying filter core in a kind of hydrogen fuel cell air supply system, by purification composite layer and containment member group
At.
The basic composition of purification composite layer is formed by being separated by filtration layer 2, adsorption cleaning layer 3, anti-charcoal ash stratum disjunction 4.
In order to enhance the protection of filter core, protective layer 1 is equipped in the outermost of purification composite layer.
For the purposes of enhancing the support of filter core, supporting layer 5 is equipped in the innermost layer of purification composite layer.
According to the specific constructive form of purification composite layer, which is divided into cartridge type and two kinds board-like.
Fig. 1 is a kind of air purifying filter core of core structure, and purification composite layer is rolled into a drum forms.It purifies compound
Layer is multilayered structure, specifically by protective layer 1, is separated by filtration layer 2, adsorption cleaning layer 3, anti-charcoal ash stratum disjunction 4, supporting layer 5 are by outer
It is arranged in order composition (Fig. 2) to inner, and with end face seal component 6 that its both ends of the surface are close in the both ends endface position of purification composite layer
Envelope so that the air outside filter core can only pass sequentially through protective layer, be separated by filtration layer, adsorption cleaning layer, anti-charcoal ash stratum disjunction, branch
Support layer enters inside filter core, and the outlet discharge finally stayed from the end face seal component 6 positioned at purification composite layer upper end is through filtering
Purified air, achievees the purpose that air purification.
The setting of protective layer 1 uses nylon wire or metal mesh to be provided substantially for filter core in outmost one layer of composite layer of purification
Protection, and the percent opening of nylon wire or metal mesh cannot be below 20%.
It is separated by filtration layer 2 and is located next to protective layer, with broad spectrum of activity charcoal and Immesion active carbon by attached after 1: 9~9: 1 mixing
It and is constituted on non-woven fabrics.Make it have the function of removal ambient liquid water, dust particles and part pernicious gas.
It is to purify mixing for the most important structure sheaf of air, especially active carbon particle and Immesion active carbon that this, which is separated by filtration layer,
Composition and division in a proportion example, NOx, NH3 in the air that specifically optionally purify, SOx, sulfide, hydrocarbon, volatile organic matter contain
Depending on amount, for example sulfur dioxide content in air is higher, then the ratio of Immesion active carbon can be selected to be more than broad spectrum of activity charcoal.
Adsorption cleaning layer 3 adsorbs main harmful hydrogen body using active carbon fiber felt next to layer is separated by filtration.
Active carbon fiber felt is the felt made of the carbon fiber by high-temperature activation.
Closely adsorption cleaning layer, adsorption cleaning layer use the textile fabric or nonwoven of 1 layer or multilayer to anti-charcoal ash stratum disjunction 4 again
Cloth is made, for preventing the active charcoal ash of the particulate matter contained in front end air and partial exfoliation to be passed into downstream.
Supporting layer 5 is located at innermost layer, is the support construction of all layers of outside.It is also to use the Buddhist nun with some strength
Imperial net or metal net are at the percent opening of mesh cannot be below 20%.
Above protective layer 1 is separated by filtration layer 2, adsorption cleaning layer 3, anti-charcoal ash stratum disjunction 4 and supporting layer 5 mutually closely,
It does not interspace between adjacent layer.
End face seal component 6 is located at the end face at filter core both ends, and end face seal component is to be bonded to cure by liquid polyurethane
Made of molding, the end face seal component positioned at purification composite layer lower end is located at purification composite layer upper end using being fully sealed
Then there are the ventholes of purification air for end face seal component.The effect of end face seal component is to ensure the leakproofness of filter material end
Can, effective sealing is provided for filter core installation, and improve filter core intensity of load.
Fig. 3 is a kind of air purifying filter core of plank frame, is that will purify the form that a plectane has been made in composite layer.Only
It is a kind of slab construction of multilayer to change composite layer, specifically by protective layer 1, is separated by filtration layer 2, adsorption cleaning layer 3, anti-charcoal ash and falls off
Layer 4, supporting layer 5 are arranged in order composition from down to up.
Since the structure of the air purifying filter core of plank frame is different from the structure of cartridge type air purifying filter core, plate type air
The edge of the purification composite layer of purifying filter element is naked state, it is therefore desirable to will purify composite layer rim with edge seal member 7
It is fully sealed, and is sealed in innermost end face end face seal component 6 and intermediate there are ventholes.
Protective layer 1 is located at outside when installing and using and is in direct contact the sky for needing to purify by plate type air purifying filter element
Gas, and supporting layer will be located at most the inside.The air purified is needed to pass sequentially through protective layer 1 from bottom to top, be separated by filtration layer 2, inhale
Attached purifying layer 3, anti-charcoal ash stratum disjunction 4, are finally discharged from the mesh of supporting layer 5, achieve the purpose that air purification.
It should be understood that for the compact consideration of composition of air content and structure of, Fig. 1 and two kinds of shapes shown in Fig. 2
Can not also set up defences sheath 1 or supporting layer 5 in the air purifying filter core of formula.
In addition, in order to filter moisture contained in the required air purified, layer 2, adsorption cleaning can also be separated by filtration
Layer 3, the outermost layer of anti-charcoal ash stratum disjunction 4 or most the inside layer or it is two layers arbitrary between increase by one layer of moisture absciss layer.Moisture absciss layer is
Made of hydrophobic fiber fabric, textile fabric or non-woven fabric made of hydrophobic fiber specifically can be used, effect is anti-
Only the liquid water in air enters inside filter core.
The making of containment member：
For cartridge type air purifying filter core, liquid polyurethane is poured into the end face of filter core composite purification layer by mold,
End face seal component 6 is formed after solidification.
For plate type air purifying filter element, liquid polyurethane is poured into the edge of filter core composite purification layer by mold,
Edge seal member 7 is formed after solidification, after glue note end face seal component 6 again.
Close the selection of the void density of the carbon fiber felt, fabric and the non-woven fabrics that use in this present embodiment, Yi Jijin
The mesh aperture size for belonging to net or nylon wire, specifically depending on ingredient in handled air or grain diameter size,
It can be realized according to common sense in the field by those skilled in the art, details are not described herein again.
The air purifying filter core in a kind of hydrogen fuel cell air supply system, including supporting layer are present embodiments provided,
Be attached on supporting layer have anti-charcoal ash fall off, the composite purification layer and protection network of gas absorption, dust-filtering function.Branch
Support layer uses nylon wire or metal mesh to provide strength support for filter core, and purification composite layer is with active carbon particle, Immesion active carbon, work
Property Carbon fibe, non-woven fabrics be raw material permutation and combination formed have particulate matter filtering, gas absorption function purifying layer, protection network adopts
Basic protection is provided for filter core with nylon wire or metal mesh, environmental damage, filter core end face is avoided to be bonded by liquid polyurethane solid
Containment member is formed after change, ensures the tightness of filter material end, provides effective sealing for filter core installation, and it is strong to improve filter core load
Degree.
