Description

Technical Field

[0001] The present invention relates to the field of purification and environmental protection technology, and specifically to a photocatalyst air disinfection module capable of evenly irradiating an optical structure. Background Art

[0002] The traditional way of applying photocatalysts is to irradiate the light source on a carrier coated with a photocatalyst on the surface. The larger the area of ​​the carrier, the better the effect of the photocatalyst. The general irradiation structure is to place the light source near the carrier and directly irradiate the carrier. For example, a photocatalyst high-efficiency air purification module proposed in the Chinese patent with application number CN201821080688.9 has an ultraviolet lamp array composed of LED ultraviolet lamp beads arranged on the top of the shell, and a layer of photocatalyst net arranged on the bottom of the shell. The photocatalyst module is a highly closed structure, and the photocatalyst module is directly irradiated by the ultraviolet lamp array to achieve an effective purification function. However, this irradiation method has the disadvantage of light divergence, especially when the space where the photocatalyst module is located is large, the light divergence is serious, which is not conducive to the effective implementation of photocatalysis. Therefore, it is necessary to make improvements. Summary of the invention

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Example

[0027] refer to Figures 1 to 6 A photocatalyst air disinfection module capable of evenly irradiating an optical structure comprises a photocatalyst module, two light source modules 1 and two multi-lens modules 2. The photocatalyst module is a horizontally arranged photocatalyst filter 5, which has a frame portion 51 and a photocatalyst filter portion 52 arranged in the frame portion 51, the photocatalyst filter portion 52 has a horizontally arranged lateral surface 53, and two light source modules 1 are symmetrically arranged on both sides of the photocatalyst filter 5.

[0028] Two multiple lens modules 2 are symmetrically arranged on both sides of the photocatalyst filter 5 and respectively located between the photocatalyst filter 5 and the light source module 1. The multiple lens modules 2 have a plurality of convex lens portions 21 arranged toward the photocatalyst filter 5. The light source module 1 and the multiple lens modules 2 are arranged close to form a photocatalytic irradiation component 3. The light source module 1 has a plurality of lamp beads 11. The lamp beads 11 are directly opposite to the convex lens portions 21 one by one, so that the lamp beads 11 and the convex lens portions 21 are assembled into a photocatalytic irradiation portion, and the photocatalytic irradiation portions are arranged in sequence and evenly distributed. The photocatalytic irradiation portion of the photocatalytic irradiation component 3 is located outside the frame portion 51 and irradiates along the lateral surface 53 of the photocatalyst filter portion 52.

[0029] The two multi-lens modules 2 are arranged on an annular frame 20, and the annular frame 20 is mounted on the outer side of the frame portion 51 of the photocatalyst filter 5. In this embodiment, the photocatalyst filter 5 adopts a rectangular structure, and the annular frame 20 also adopts a rectangular structure accordingly. In the above structure, the photocatalyst filter 5 integrates photocatalytic technology and filtering functions, and plays a role in filtering and purifying the airflow passing through.

[0030] The photocatalyst air disinfection module of this embodiment has the following advantages: first, the convex lens portion 21 in the multi-lens module 2 can focus the light emitted by the light source module 1 onto the photocatalyst module, so that the photocatalyst material can receive more concentrated and stronger light. This focusing effect can significantly improve the photocatalytic efficiency of the photocatalyst, especially when processing reactions that require higher light intensity.

[0031] Second, the photocatalytic irradiation part assembled by the lamp bead part 11 and the convex lens part 21 is evenly arranged, so that the surface of the photocatalyst module can obtain a more uniform light distribution. Uniform light can ensure that all parts of the photocatalyst material can effectively participate in the photocatalytic reaction, avoiding low reaction efficiency caused by uneven light.

[0032] Third, the light emitted by the light source module 1 is focused by the multiple lens module 2 and then irradiated onto the photocatalyst module, thereby preventing the light source from being directly exposed to the external environment. This not only improves the safety of the disinfection module and reduces the divergence of light, but also prevents the light from radiating out of the disinfection module, thereby reducing the potential harm to the surrounding environment caused by the divergence of light.

[0033] Fourth, by arranging the photocatalytic irradiation components 3 on both sides of the photocatalyst filter 5, the photocatalyst filter 5 can receive light from two directions at the same time. This double-sided illumination method allows the surface of the photocatalyst filter 5 to fully contact the light source, significantly increasing the effective illumination area of ​​the photocatalyst material, thereby greatly improving the efficiency of the photocatalytic reaction.

[0034] Fifth, the photocatalytic irradiation component 3 is located outside the photocatalyst filter 5, which can effectively avoid resistance to the airflow passing through the photocatalyst filter 5, thereby reducing wind resistance, ensuring airflow velocity, reducing energy consumption, and being more efficient and environmentally friendly.

[0035] Furthermore, the multi-lens module 2 has a plurality of condenser covers 22 arranged facing the light source module 1 , the convex lens parts 21 , the condenser covers 22 and the lamp beads 11 are arranged one by one, and the lamp beads 11 are placed in the condenser covers 22 and then illuminate the convex lens parts 21 .

[0036] In the above structure, dual focusing is achieved through the combination of the focusing cover part 22 and the convex lens part 21. The focusing cover part 22 first focuses the light emitted by the lamp bead part 11, and then performs secondary focusing through the convex lens part 21, reducing the scattering and loss of light during the propagation process, so that the light is irradiated more concentratedly on the photocatalyst module. This dual focusing mechanism can significantly increase the light intensity of the photocatalyst module, thereby improving the photocatalytic efficiency.

[0037] Furthermore, the photocatalyst filtering portion 52 of the photocatalyst filter 5 is folded, and a plurality of long concave folds 54 are evenly distributed on its transverse surface 53 , and each photocatalytic irradiation portion of the photocatalytic irradiation assembly 3 is arranged in one-to-one correspondence with the concave folds 54 .

[0038] In the above structure, the photocatalytic irradiation part of the photocatalytic irradiation assembly 3 is arranged one-to-one with the concave folded part 54, which can ensure that each folded part 54 can receive uniform light. This design can avoid the low efficiency of the photocatalytic reaction caused by uneven light, and further improve the uniformity and efficiency of the photocatalytic reaction.

[0039] This embodiment further uses the lateral surface 53 of the photocatalyst filter 52 as the windward surface of the photocatalyst filter 5. In the above structure, the lateral surface of the photocatalyst filter 52 is used as the windward surface, so that the photocatalyst material can more effectively contact the pollutants in the air or fluid, thereby improving the degradation efficiency of the pollutants.

[0040] This embodiment further includes a main board 6 and a main board heat sink 61 disposed on the outer side of the main board 6, the main board 6 is electrically connected to the light source module 1, and the main board 6 and the main board heat sink 61 are installed on the outer side of the annular frame 20. In addition, a heat dissipation module 13 is also disposed on the side of the light source module 1 away from the lamp bead portion 11. In the above structure, the heat dissipation module 13 and the main board heat sink 61 are used to reduce the temperature of the light source module 1 and the main board 6 respectively, thereby extending their service life and improving the stability and reliability of the disinfection module.
