Abstract
The utility model belongs to the air technical field and discloses a composite air filter paper, wherein, the filter paper is corrugated and consists of a prior plant fiber filter paper layer and a chemical fiber nonwoven fabric layer combined with the side face of the filter paper layer. The utility model solves the problem of short effective service time of the prior plant fiber filter paper; moreover, the composite air filter paper which adopts the structure has the characteristics of high filtering efficiency, long filtering time and fast filtering rate.
Description
Technical field
The utility model belongs to the air filtration technical field, relates in particular to a kind of composite air filtering paper that is applicable to filtered air.
Background technology
Air filter paper utilizes microporous paper to be situated between exactly air is filtered, and isolates particle suspensions from air, thereby reaches the purpose of pure air.At present, employed air filter paper is that the traditional string filter paper layers of one deck constitutes, be used for the filter process of air, because structural defective exists following shortcoming: because the thickness limits that paper is situated between, the particle suspensions of being filtered is easy to fill up medium, makes that its effective filtration time is shorter; Because the restriction on the filter area, the rate of filtration is lower.
The utility model content
The purpose of this utility model just provides a kind of composite air filtering paper that effective filtration time is long, the rate of filtration is fast that has.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of composite air filtering paper includes traditional plant fiber filter ply of paper, and the side of described traditional plant fiber filter ply of paper is compounded with the chemical fibre nonwoven layer.
Its additional technical feature comprises: described traditional plant fiber filter ply of paper is a corrugated; Described chemical fibre nonwoven layer is a corrugated.
Composite air filtering paper provided by the utility model compared with prior art, have the following advantages: one, because this composite air filtering paper is made of traditional plant fiber filter ply of paper and chemical fibre nonwoven layer bilayer, degree of filtration than original filter paper has improved more than 0.50%, has reached 99.98%; Its two since many micropores characteristics of compound chemical fibre nonwoven layer, make the storage ash amount of this composite air filtering paper increase, and the suspended particulate in the chemical fibre nonwoven layer is easy to remove, therefore have the long advantage of filtration time; Its three because this composite air filtering paper is corrugated, promptly increased filter area, improved the rate of filtration and held the volume of dirt.
Description of drawings
Accompanying drawing is the structural representation of composite air filtering paper.
The specific embodiment
The structure of the composite air filtering paper that the utility model is provided below in conjunction with accompanying drawing is described in further details.
As shown in the figure, the structural representation of the composite air filtering paper that provides for the utility model.Promptly the basic structure of this composite air filtering paper includes traditional plant fiber filter ply of paper 1 and at the compound chemical fibre nonwoven layer in the side of this traditional plant fiber filter ply of paper (also being nonwoven layer) 2.
In order to improve the filter area of this composite air filtering paper, the composite air filtering that constitutes is pressed into corrugated.
In said structure, certainly have only traditional plant fiber filter ply of paper 1 to be the corrugated structure.
Claims (3)
1. a composite air filtering paper includes traditional plant fiber filter ply of paper, it is characterized in that: the side of described traditional plant fiber filter ply of paper is compounded with the chemical fibre nonwoven layer.
2. a kind of composite air filtering paper according to claim 1 is characterized in that: described traditional plant fiber filter ply of paper is a corrugated.
3. a kind of composite air filtering paper according to claim 1 is characterized in that: described chemical fibre nonwoven layer is a corrugated.
