Description

Technical Field

[0001] The utility model belongs to the technical field of air purification, and in particular relates to an air purification component with high efficiency, low resistance and high dust holding capacity. Background Art

[0002] As people's living standards improve, they pay more and more attention to air quality. PM2.5 particles, harmful gases and other pollutants in the air are extremely harmful and can easily cause respiratory and cardiovascular diseases. They are the first pollutants to be removed. The current air purification method mostly uses air filter materials to make air filter components through folding processing, which are installed in air conditioning ventilation purification systems, air purifiers and other equipment for use. However, the dust holding capacity of the current air purification component is small during the air purification process. After a period of use, the dust holding capacity will be full, which will cause a sharp increase in filtration resistance and a decrease in efficiency. The filter component needs to be replaced frequently, and the use and maintenance costs are high. CN219647031U discloses a clean room air filter component, including a housing, a folded filter element and a frame. The folded filter element is passed through a groove, and the number of filter element replacements is reduced by arranging guide rollers and drive rollers on both sides of the groove. CN219333528U discloses a polygonal air filter component, including a frame, a protective net and a filter element. The filtering effect is improved by covering more ventilation area with a regular polygonal frame. Summary of the invention

[0003] In order to solve the above technical problems, the utility model discloses an air purification component with high efficiency, low resistance and high dust holding capacity, which has the advantages of high filtration efficiency, small operation resistance, large dust holding capacity and long service life, and greatly reduces the cost of use and maintenance.

[0004] The technical solution of the utility model is as follows: an air purification component with high efficiency, low resistance and high dust holding capacity, which comprises, from front to back, a dust facing surface, a transition layer, a dust holding layer, a dust holding cavity, a filter layer, an electrostatic adsorption layer and a catalytic decomposition layer. The dust facing surface, the transition layer and the dust holding layer are made of organic porous materials, and the pore sizes increase successively. The filter layer is formed by folding filter paper with a folding spacing of 5-10mm and a folding height of 40-80mm. The dust holding cavity is surrounded by folded peaks and valleys of the dust holding layer and the filter layer. The electrostatic adsorption layer is made of electrostatic cotton laid flat or folded.

[0005] Furthermore, the dust-facing surface is made of a polypropylene film or a polyurethane film with a pore size of 20-100 μm and a thickness of 1-3 mm, and is detachably connected to the transition layer by magic adhesive.

[0006] Furthermore, the transition layer is made of polyester film or polyurethane film, has a pore size of 100-300 μm, a thickness of 1-2 mm, and is detachably connected to the dust holding layer via magic adhesive.

[0007] Furthermore, the dust holding layer is made of a polyester film or a polyurethane film, has a pore size of 300-500 μm, and a thickness of 2-4 mm, and is detachably connected to the filter layer by magic adhesive.

[0008] Furthermore, the filter layer is made of double-layer material by hot pressing, the material is polytetrafluoroethylene film or polypropylene film, and reinforcing ribs are provided perpendicular to the folding direction, and the reinforcing ribs are fixed to the filter paper material by hot melt adhesive.

[0009] Furthermore, the electrostatic cotton of the electrostatic adsorption layer has a pore size of 20-50 μm and a thickness of 1-3 mm.

[0010] Furthermore, the catalytic decomposition layer has a thickness of 3-8 mm and is made of a honeycomb mesh filled with catalytic decomposition particles.

[0011] Beneficial effects: The high-efficiency, low-resistance, high-dust-holding-capacity air purification component disclosed by the utility model adopts a gradient hole filter material on the air inlet side to detachably form a dust-facing surface, a transition layer, and a dust-holding layer. The dust-facing surface has the smallest diameter, which can effectively block large particles such as hair and flying catkins in the air from entering the interior of the component. The filter layer is located between the dust-facing surface and the dust-holding layer, and the pore diameter is larger than the dust-facing surface and smaller than the dust-holding layer. The running speed of particles passing through the dust-facing surface can be reduced, so that the particles repeatedly collide inside the material and are intercepted and filtered by the material fibers. The filter layer plays a major filtering role, and the finer particles passing through the dust-facing surface, the transition layer, and the dust-holding layer are intercepted by the filter layer. The intercepted particles accumulate in the dust-holding cavity. Due to the blocking effect of the dust-holding layer, the particles in the dust-holding cavity can be effectively prevented from being blown away by the airflow, causing secondary pollution. The provision of the dust-holding layer and the dust-holding cavity greatly increases the dust-holding capacity of the purification component and extends the service life of the purification component.
