Abstract
The utility model provides a fine filter media of high -efficient filtration glass, includes dust particle filter layer, dust filter layer, particle filter layer, its characterized in that: the dust particle filter layer include first filter layer and second filter layer, the dust filter layer include third filter layer and fourth filter layer, the particle filter layer include the 5th filter layer, the 6th filter layer, the 7th filter layer and the 8th filter layer. The utility model has the advantages of this filter media can be applied to the baffle or not have the high -efficient air cleaner in toilet of baffle. Under the same condition of ration, the resistance that the structural design of multilayer (more than eight layers or eight layers) can reduce the filter media than the fine filter media design of traditional individual layer glass improves more than the filter life 20% more than 20%.
Description
Technical field
The utility model relates to a kind of high-efficiency air filtering glass filter material, is specifically related to a kind of high-efficiency air filtering glass filter material of sandwich construction.
Background technology
The glass filter material being applied to high-efficiency air filtering is at present all single layer structure, namely the distribution of glass fibre on filter material cross section is more uniform, the weak point of this structure is that the resistance of filter material rose, because the hole of surface of filter medium has been blocked by large particle very soon very soon along with the time.Due to filter material arrive certain resistance after must change, therefore cause the life-span of filter material shorter, add the replacement frequency of filter, both added replacement cost and energy consumption, result also in the reduction of production efficiency.
utility model content
The utility model is intended to overcome shortcoming of the prior art, provides the high-efficiency air filtering glass filter material of a kind of lower resistance, high life.
The distribution of solid particulate matter from air, the mass percent shared by the particle that size is larger is larger, but number percent is less; Mass percent shared by the particle that size is less is less, but number percent is larger.For solid particulate matter distribution character in air, the technical scheme that the utility model adopts multilayer to filter step by step, namely filters solid particulate matter from big to small successively.In order to ensure that glass filter paper has certain intensity, the utility model can add a small amount of synthetic fibers in each layer glass and acrylic resin strengthens.
A kind of high-efficiency air filtering glass filter material that the utility model provides, its concrete technical scheme is as follows:
A kind of high-efficiency air filtering glass filter material, comprises grit filter course, dust filtering layer, particle filter layer, it is characterized in that: described grit filter course comprises the first filter course and the second filter course; Described dust filtering layer comprises the 3rd filter course and the 4th filter course; Described particle filter layer comprises the 5th filter course, the 6th filter course, the 7th filter course and the 8th filter course; The air permeability of the first described filter course is greater than the second filter course, the air permeability of the second described filter course is greater than the 3rd filter course, the air permeability of the 3rd described filter course is greater than the 4th filter course, the air permeability of the 4th described filter course is greater than the 5th filter course, the air permeability of the 5th described filter course is greater than the 6th filter course, the air permeability of the 6th described filter course is greater than the 7th filter course, and the air permeability of the 7th described filter course is greater than the 8th filter course.
Preferably, described each filter course is mixed by the glass fibre of two or more different air permeability and makes.
The beneficial effects of the utility model are: this filter material can be applicable to toilet's high efficiency particle air filter of dividing plate or non-inductive windings.When quantitatively identical, the structural design of multilayer (more than eight layers or eight layers) can reduce the resistance more than 20% of filter material than the design of traditional individual layer glass filter material, improves filter service life more than 20%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 11. grit filter courses; 12. dust filtering layers; 13. particle filter layer; 1. the first filter course; 2. the second filter course; 3. the 3rd filter course; 4. the 4th filter course; 5. the 5th filter course; 6. the 6th filter course; 7. the 7th filter course; 8. the 8th filter course.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described further.
As shown in Figure 1, the multilayer glass filter material involved by the utility model is made up of the filter course of more than eight layers or eight layers, and every layer of filter course has the glass fibre of two or more different air permeabilities to mix.From the first filter course to the 8th filter course, the content of fine glass fibre increases gradually, and air permeability reduces gradually, and filter efficiency also increases gradually.By allocating the efficiency gradient between each layer, the filter efficiency that can control whole filter material reaches the high efficiency filter level of efficiency (H13 and H14) of EN1822:2008 defined.
Embodiment
A kind of filtration grade is eight layers of gradient glass filter material of H13.First filter course is 300cfm(125Pa pressure reduction by air permeability, lower with) glass composition, the glass that the second filter course is 200cfm by air permeability forms, and the first filter course and the second filter course form grit filter course jointly, the grit in filtered air; The glass that 3rd filter course is 120cfm by air permeability forms, and the glass that the 4th filter course is 80cfm by air permeability forms, and the 3rd filter course and the 4th filter course form dust filtering layer jointly; The glass that 5th filter course is 30cfm by air permeability forms, the glass that 6th filter course is 20cfm by air permeability forms, the glass that 7th filter course is 15cfm by air permeability forms, the glass that 8th filter course is 8cfm by air permeability forms, the 5th filter course, the 6th filter course, the 7th filter course and the 8th filter course composition particle filter layer.
The utility model relates to a kind of sandwich construction glass filter material, is mainly used in the high-efficiency air filtering of toilet.The purpose of this utility model reduces the resistance of conventional monolayers glass filter material, extends the service life of filter.Multilayer filter material of the present utility model is made up of the glass filter material of more than eight layers or eight layers, and every one deck is mixed with certain proportion by the glass of two or more different air permeability.From ground floor (upstream) to the 8th layer (downstream), the air permeability of every one deck reduces gradually, and filter efficiency improves gradually.This filter material can be applicable to toilet's high efficiency particle air filter of dividing plate or non-inductive windings.When quantitatively identical, the structural design of multilayer (more than eight layers or eight layers) can reduce the resistance more than 20% of filter material than the design of traditional single layer filter layer, improves filter service life more than 20%.
