Description

Technical Field

[0001] The invention belongs to the technical field of air purification, in particular to a composite air filtering device. Background Art

[0002] Industrial waste gas purification refers to the removal or transformation of harmful gases, pollutants and harmful components generated in the industrial production process through physical, chemical or biological methods, thereby reducing their harm to the environment and human health and ensuring that waste gas emissions meet relevant environmental protection standards.

[0003] In the prior art, most air purification devices use a single air filter to remove pollutants, but this single filtering method often cannot effectively deal with complex air pollution problems; for example, the "air filter" disclosed in the patent document "CN115569449A" uses a glass fiber filter element for filtering, which is difficult to effectively treat a variety of pollutants (such as particulate matter or gas), and a single filtering method is difficult to provide a comprehensive purification effect. For example, the HEPA filter is effective for fine particulate matter, but has limited ability to remove gaseous pollutants such as volatile organic compounds and odors; and although the activated carbon filter has a certain adsorption effect on gaseous pollutants, the filtering efficiency of particulate matter is low.

[0004] In addition, existing air filters filter the air through two layers of filters. For example, the "air filter" disclosed in the patent document "CN105854458A" has a technical solution that uses a main filter part and a secondary filter part for filtering. However, the main filter part and the secondary filter part only limit the different sizes of particles in the air, and it is difficult to filter other types of pollutants in the air.

The inner cavity of the centrifugal cylinder 11 is cylindrical. The air inlet pipe 12 is tangentially connected to the centrifugal cylinder 11 so that the outlet of the air inlet pipe 12 is tangential to the inner wall of the centrifugal cylinder 11.

[0038] The second filter element 2 includes a glass fiber filter element 21 and activated carbon. The glass fiber filter element 21 is installed in the centrifugal cylinder 11, and the activated carbon is installed in the glass fiber filter element 21.

[0039] The microbial filtration mechanism 3 includes a microbial layer 31 and a heating component 32. The heating component 32 is used to heat the microbial layer 31, and the gas passing through the activated carbon enters the microbial layer 31;

[0040] The ultraviolet mechanism 4 includes an ultraviolet irradiation unit 41, which is electrically connected to the control module 5. The control module 5 is used to control the ultraviolet irradiation unit 41 to emit ultraviolet rays, and the gas passing through the microbial layer 31 enters the ultraviolet irradiation unit 41;

[0041] The adaptive adjustment mechanism 6 includes an adjustable filter layer, and the aperture of the adjustable filter layer can be adjusted according to the air flow rate;

[0042] A top cover 7, on which the regulating filter layer is installed, the top cover 7 is connected to the centrifugal cylinder 11 through a connecting ring 8, and the top cover 7 is provided with an air outlet pipe 9, which is in communication with the top cover 7;

[0043] The gas passes through the centrifugal cylinder 11, the glass fiber filter element 21, the activated carbon, the microbial layer 31, the ultraviolet irradiation unit 41 and the adjustment filter layer in sequence from the air intake pipe 12, and the control module 5 adjusts the pore size of the adjustment filter layer according to the air filtration standard and the air flow rate.

[0044] Specifically, when polluted air enters the composite air filter device of the present application through the air intake duct 12, in the first step, the gas will enter the centrifugal filter mechanism 1. In the centrifugal filter mechanism 1, the direction of the airflow entering is tangent to the inner wall of the centrifugal cylinder 11, so that the gas forms a high-speed rotating airflow, and then the larger particles in the airflow are thrown to the inner wall of the centrifugal cylinder 11 due to the action of centrifugal force, thereby realizing the first filtration of the gas and facilitating the discharge of the gas; then, the gas after the preliminary centrifugal filtration continues to pass through the glass fiber filter element 21, and the glass fiber filter element 21 can effectively capture fine particles, especially fine dust and microparticles, and also has a certain filtering effect on some larger pollutants in the gas. The glass fiber filter element 21 can further purify the air and improve the filtering effect; the gas continues to pass through the activated carbon layer, and the activated carbon can adsorb volatile organic compounds, odors, odors and some gaseous pollutants in the air, effectively remove gaseous pollutants in the air, and significantly reduce harmful gas components in the air; the filtered gas then flows into the microbial filtration mechanism 3, and the microbial layer 31 can be used to treat harmful microorganisms that may remain. It is worth noting that the microbial layer 31 in this embodiment is composed of microorganisms that are harmless to the human body, and the microbial layer 31 contains a catalyst. The heating component 32 will heat the microbial layer 31 to provide a suitable temperature to enhance the inactivation effect of microorganisms.

It is worth noting that although the above-mentioned microbial layer 31 is composed of harmless bacteria, the use of the ultraviolet irradiation unit 41 can still eliminate the microorganisms brought out of the above-mentioned microbial layer 31. It is worth noting that the ultraviolet mechanism 4 is located at the top cover 7, and the microbial filtering mechanism 3 is located at the centrifugal cylinder 11. The light of the ultraviolet irradiation unit 41 will not hit the microorganism layer 31.

The control module 5 is provided with a built-in algorithm to ensure that the effect of the ultraviolet rays is optimal. Of course, the ultraviolet intensity can also be controlled by manually adjusting the control module 5; after ultraviolet irradiation, the gas will pass through the adjusting filter layer, and the adjusting filter layer can dynamically adjust the pore size. By dynamically adjusting the pore size, blockage caused by excessive dust accumulation can be avoided. When the pollutant concentration is high, the pore size can be slightly increased to reduce the clogging speed of the adjusting filter layer; and when the pollutants are less, the pore size can be reduced to improve the filtering effect.This not only helps to extend the service life of the equipment, but also reduces maintenance costs, ensures smooth airflow and further filters residual tiny particles, thereby ensuring the stability and adaptability of the filtering effect; after being processed by the composite air filtration device, the air passes through the centrifugal filtration mechanism 1 to preliminarily remove most of the coarse particles, flows through the glass fiber filter element 21, and fine particles such as PM2.5 and pollen are further filtered, and through the activated carbon layer, volatile organic compounds, odors, odors and harmful gases are adsorbed, and the heated air passes through the microbial filtration layer, and the DNA of microorganisms is further destroyed by the ultraviolet irradiation unit 41 to enhance the sterilization effect, and through the filter layer with adaptively adjusted pore size, fine particles and residual gaseous pollutants are further filtered and removed to ensure that the air achieves the best purification effect; after these multiple purification steps, particulate matter, gaseous pollutants, microorganisms and odors in the air have been effectively removed, and the air finally discharged into the environment is fresh, odorless, and free of harmful substances, meets environmental emission standards, significantly improves air quality, and provides clean and safe air for the environment.

The top of the filter cylinder 13 extends outward to form an annular flange 14, which is fixedly connected to the inner wall of the centrifugal cylinder 11 to ensure that the filter cylinder 13 is firmly installed. The top of the glass fiber filter element 21 extends outward to form an annular flange 2, which is inserted into the inner wall of the filter cylinder 13 and is tightly connected to the filter cylinder 13 to ensure the stability of the glass fiber filter element 21.

The activated carbon baffle 23 on the top of the glass fiber filter element 21 is connected to the bottom of the groove of the container plate to ensure the stable position of the activated carbon and avoid leakage of the activated carbon.
