Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 2, in an embodiment of the present invention, an air purification filter element for a hydrogen fuel cell includes a filtering and adsorbing layer and a frame member 3. The filtering and adsorbing layer is of a multilayer structure and is formed by sequentially arranging from bottom to top, and the number of layers is not less than two and is set according to actual needs. Each layer of the filtering and adsorbing layer is longitudinally pleated, and the pleating directions of adjacent layers are mutually staggered to form staggered channels. The material of the filtering and adsorbing layer is activated carbon non-woven fabric, and each layer of the filtering and adsorbing layer contains different activated carbon components.
The filtering and adsorbing layer is of a double-layer structure, the upper layer is a first filtering and separating layer 1, and the lower layer is a second filtering and separating layer 2. The first filtering separation layer 1 and the second filtering separation layer 2 are formed by longitudinally pleating and alternately superposing activated carbon non-woven fabrics containing different activated carbon components to form staggered channels, so that air flow is uniformly distributed, and conducted noise is effectively absorbed.
The cross section all around of filtering the adsorbed layer passes through hot melt adhesive bonding skeleton member 3 to the support of reinforcing filter core. Simultaneously, the setting of skeleton member 3 makes to filter the adsorbed layer and can seal all around, and the air of filter core outside can only loop through filtration separation layer 1, filters separation layer two 2, reaches the purpose to air purification, and amortization fall the noise.
The framework component 3 is formed by bonding hard non-woven fabrics on the end surface of the filtering and adsorbing layer through hot melt adhesive, so that the tightness of the end part of the filter material is ensured, and the load strength of the filter element is improved.
The filter separation layer used in this embodiment is determined by the size of the components or particles contained in the air to be treated, and can be realized by those skilled in the art according to the general knowledge in the art, and will not be described herein again.
The embodiment has only demonstrated two-layer filtration adsorbed layer and has vertically wrinkled crisscross stack to through the hot melt adhesive cross section bonding skeleton member all around, multilayer (more than two-layer) or each individual layer are alone through the hot melt adhesive cross section bonding skeleton member all around after, constitute crisscross superimposed condition and all belong to the utility model discloses a category.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
