The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
An air purification filter screen 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
The utility model discloses air purification filter screen 100, as shown in fig. 1 and fig. 5, including filter screen body 1 with adhere to the adhesion layer on filter screen body 1, filter screen body 1's relative both sides surface is windward side and leeward side respectively, is equipped with a plurality of filtration pores 2 that link up from windward side to leeward side on filter screen body 1, and the at least part of adhesion layer is located the inner wall of filtration pore 2, and the adhesion layer is formaldehyde decomposition catalyst layer.
It can be understood that the windward side and the leeward side are two opposite surfaces of the filter screen body 1, untreated air flows in from the windward side of the filter screen body 1 and flows out from the leeward side of the filter screen body 1, the air passes through the filter screen body 1, and when formaldehyde gas in the air meets a formaldehyde decomposition catalyst layer, the air can be rapidly decomposed, so that the air purification filter screen 100 has formaldehyde filtering capability. Of course, when the air flow passes through the filter screen body 1 in opposite directions, the windward side and the leeward side of the filter screen body 1 are interchanged.
According to the utility model discloses an air purification filter screen 100 sets up formaldehyde decomposition catalyst layer through the inner wall at filtration pore 2, and the air is when flowing through filtration pore 2, and the formaldehyde gas in the air decomposes under formaldehyde decomposition catalyst's catalytic action fast, and air purification filter screen 100 has formaldehyde filtering function. The formaldehyde decomposition catalyst is located on the inner wall of the filter hole 2, and the contact area between the formaldehyde decomposition catalyst and the air flowing through can be increased without influencing the original filtration effect on the air, so that the formaldehyde decomposition efficiency is improved, and the decontamination efficiency is high.
Alternatively, the adhesion layer is attached to the inner wall of the filter pores 2 by spraying or smearing or dipping, but may be formed by other methods.
Optionally, as shown in fig. 4 and 5, the extending directions of the at least two filtering holes are not equal to the included angle a between the windward side.
A plurality of through filter holes 2 are formed in the filter screen body 1, the filter holes 2 are through filter holes 2 from the windward side to the leeward side, the air flow direction of the filter holes 2 can be guided, and attachment points of the formaldehyde decomposition catalyst layer are provided on the inner walls of the filter holes 2. The air flows into the filter screen body 1 from the windward side, and the extending direction of the filter holes 2 is the flow guide direction of the filter holes 2 to the air. When the inclination angle of the central line of the filter hole 2 relative to the windward side is equal to the inclination angle of the inner wall of the filter hole 2 relative to the windward side, the included angle a between the extending direction of the filter hole 2 and the windward side is equal to the included angle between the central line of the filter hole 2 and the windward side. When the inclination angles of the inner walls of the filter holes 2 on different sides with respect to the windward side are different, the extending direction of the filter holes 2 can be obtained through experiments, for example, air is blown in from the direction perpendicular to the windward side, and the direction of the blown air passing through the filter holes 2 is measured, wherein the blown air direction is equal to the flow guiding direction of the filter holes 2 to the air.
When the included angle a between the extending direction of the filter holes 2 and the windward side is larger, the extending direction of the filter holes 2 is more close to being vertical to the windward side, the wind resistance of air passing through the filter holes 2 is minimum, and the noise is also minimum; when the included angle a between the extending direction of the filter holes 2 and the windward side is reduced, the air and the inner walls of the filter holes 2 have certain impact, the smaller the included angle a is, the more violent the air and the inner walls of the filter holes 2 collide, the larger the change of the wind direction is, certain turbulence or backflow is generated, so that the air has more chances to contact the inner walls of the filter holes 2, and the contact time with the formaldehyde decomposition catalyst layer is prolonged.
The formaldehyde decomposition catalyst layer is arranged on the inner walls of the filter holes, and because the extending directions of at least two filter holes 2 are not equal to the included angle a between the windward side, the extending direction of at least one filter hole 2 is not vertical to the windward side, the inclined arrangement mode increases the area of the inner walls of the filter holes 2, and the formaldehyde decomposition catalyst layer can have more inner wall areas for attachment. And the time for the air molecules to contact the formaldehyde decomposition catalyst layer is prolonged when the air hits the inclined inner wall, thereby improving the decomposition efficiency of the formaldehyde component in the air. In addition, when air passes through the filter holes 2, the extending direction of the filter holes 2 influences the flowing direction of the air, and by setting the extending direction of at least two filter holes 2 to be different, turbulent flow or backflow can be generated when the air in different directions meets, so that air molecules have more chances to contact with the formaldehyde decomposition catalyst layer, and the decomposition efficiency of the formaldehyde component in the air is further improved.
In some embodiments, as shown in fig. 3 and 4, the angle a between the extending direction of the filter holes 2 and the windward side is in the range of 45 degrees to 90 degrees.
Through many calculations and experiments of research and development teams, it is determined that the effect of the included angle a between the extending direction of the filter holes 2 and the windward side is better when the included angle a ranges from 45 degrees to 90 degrees, and when the included angle between the filter holes 2 and the surface of the filter screen body 1 ranges from 45 degrees to 90 degrees, the wind resistance is smaller, the energy consumption is lower, and a better filtering effect can be achieved.
For example, the angle a between the extending direction of the filter holes 2 and the windward side is 45 degrees, 60 degrees, 75 degrees, 85 degrees, and the like.
Optionally, the thickness of the hole wall of the filter hole 2 is 0.02 to 1 mm, so that the hole wall of the filter hole has certain strength to bear wind pressure, and the filter hole does not occupy too much air circulation space and is favorable for reducing wind resistance.
For example, the thickness of the wall of the filter hole 2 is 0.02 mm, 0.05 mm, 0.1 mm, 0.9 mm, 1 mm, or the like.
Alternatively, the filter holes 2 have a hole area of 2 to 10 square millimeters so that a unit amount of air can be in contact with a larger area of the formaldehyde decomposition catalyst layer and the formaldehyde gas can be sufficiently decomposed. For example, the pore area of the filter pores 2 is 2 or 4 or 6 or 8 or 10 square millimeters, etc.
Alternatively, the filter screen body 1 has 60 to 300 filter holes 2 per square inch, which can increase the contact area of the adhesion layer with air, thereby increasing the filtering effect of the air purifying filter screen 100.
Optionally, the ratio of the average diameter of the filter holes 2 to the depth of the filter holes 2 ranges from 0.1 to 1, the depth of the filter holes 2 is larger than the average diameter of the filter holes 2, the contact time of the air flowing through the filter holes 2 and the inner wall of the filter holes 2 is prolonged, the flow of the air in the filter holes 2 is improved, the contact effect of the air and the adhesion layer is increased, and the filtering effect of the air purification filter screen 100 on the air is improved.
Optionally, the surface of the filter hole 2 has an anodic oxidation layer.
The anodic oxidation layer is additionally arranged on the surface of the filter hole 2, so that the binding force between the surface of the filter hole 2 and the adhesion layer can be improved, the loading capacity of the surface of the filter hole 2 on the adhesion layer can be increased, and the catalytic efficiency can be improved. In addition, the anodized layer has a certain protective effect on the surface of the filter holes 2 and is resistant to corrosion, thereby increasing the service life of the air purification filter screen 100.
In some embodiments, the porosity of screen body 1 is between 90% and 98%.
The porosity of filter screen body 1 is the ratio of the total volume of filtration pore 2 in filter screen body 1 to the total volume of filter screen body 1, and the porosity is great to explain the volume of filtration pore 2 great, and then the pore wall and the adhesion layer volume that carries are all great to can improve the area of contact of adhesion layer and air, improve the filter effect to the air.
Optionally, the surface roughness of the inner wall of the filter hole 2 is equal to or less than the surface roughness of the adhesion layer.
The adhesive force between the adhesive layer and the filter pores 2 can be improved, thereby improving the purification efficiency of the formaldehyde decomposition catalyst layer. Through the arrangement, the thickness of the adhesion layer can be smaller, so that the air circulation efficiency is ensured, and the catalysis efficiency can be ensured at the same time.
Optionally, the inner walls of the filter pores 2 have a surface roughness of 0.4-5 microns.
In some embodiments, the filter screen may be made of aluminum foil, and the aluminum foil is subjected to surface treatment in a manner including: grinding, sand blasting, sanding, anodizing and the like can make the surface roughness of the filter screen body 1 be 0.4-5 microns. Filter screen body 1 has certain surface roughness, can improve filter screen body 1's adhesive force, increases the contact with the air, improves purification efficiency. And the adhesive force of the filter screen body 1 is increased, and a foundation is laid for the installation of an adhesive layer attached to the filter screen body 1 in the next step.
Optionally, the surface roughness of the adhesion layer is 5-20 microns, that is, after the adhesion layer is attached, the surface roughness of the inner wall of the filter hole 2 is 5-20 microns, so that the filter hole 2 after the adhesion layer is loaded has a roughness within a certain range, the effect of breaking and shunting air on the inner wall of the filter hole 2 is increased, the contact effect and the reaction time of the air and the adhesion layer are improved, the catalysis efficiency is further improved, and the air filtering effect is improved.
In some embodiments, the screen body 1 is a porous media mesh or a honeycomb mesh.
In some embodiments, as shown in fig. 1, the filter screen body 1 is a porous medium screen, wherein the porous structure may be a triangle, a quadrangle, a pentagon, a hexagon, a fan, a circle, etc., and the porous structure may be designed individually as required, which may improve the overall aesthetic appearance of the air purification filter screen 100.
In other embodiments, as shown in fig. 2, the filter screen body 1 is a honeycomb net, and the porous structure is a regular hexagon, which can improve the overall strength of the filter screen body 1, is not easy to be damaged, and prolongs the service life.
Alternatively, the total loading of the adhesion layers on the inner walls of the filter pores 2 is 97% or more of the total adhesion layers, so that the adhesion layers outside the inner walls of the filter pores 2 are within 3% of the whole.
The air purification filter screen 100 is formed by attaching an adhesive layer on the surface of the whole filter screen body 1, and the total amount of the adhesive layer attached to the inner wall of the filter holes 2 is more than 97% of the total amount of the adhesive layer. Compared with the surface of the filter screen body 1, the air flow flux in the inner wall of the filter hole 2 is larger, so that the attached layer attached to the inner wall of the filter hole 2 is more on the surface of the filter screen body 1, and the filtering effect of the air purification filter screen 100 can be improved.
Optionally, the filter screen body 1 is a metal mesh or a paper mesh or a ceramic mesh.
The material of filter screen body 1 can be multiple material, can be the metal mesh, paper net or ceramic screen, and filter screen body 1 has reduced to the filter effect of air, and the adnexed adhesion coating that carries on filter screen body 1 plays main filtration purification effect, consequently does not strictly require the material of filter screen body 1 to filter screen body 1, satisfies certain intensity and can select filter screen body 1's material according to pleasing to the eye degree or lightweight to other special requirements.

Therefore, the structure with the consistent extension direction of the filter holes 2 can be processed when a single body unit is processed, and the processing is convenient. Optionally, the extension direction of the filter holes on every two adjacent body units is changed once.
