DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 A VOC waste gas treatment device includes a treatment tower 1, which is provided with an air inlet 11 and an exhaust port 12. A multi-layer photocatalytic component 2 is arranged in the treatment tower 1; the VOC waste gas sent into the treatment tower 1 is photocatalytically oxidized and degraded and purified by the photocatalytic component 2.

[0028] The photocatalytic assembly 2 includes a purification drawer 21 horizontally inserted into the treatment tower 1 and extending vertically therethrough; a hanging plate 22 disposed at the upper end of the purification drawer 21, the hanging plate 22 having a ventilation opening 221 formed therein; and a UV lamp assembly 23 and a catalyst assembly 24 disposed at the lower end of the hanging plate 22. The UV lamp assembly 23 comprises multiple layers of UV lamp tubes 231 arranged in an annular pattern, and the catalyst assembly 24 comprises multiple layers of first catalyst carrier plates 241 arranged in an annular pattern, with the UV lamp tubes 231 and the first catalyst carrier plates 241 being arranged alternately. The catalyst carried on the first catalyst carrier plates 241 can be a titanium dioxide photocatalyst. Ultraviolet light emitted by the UV lamp tubes 231 excites the catalyst's catalytic activity and oxidizing capacity through ultraviolet radiation, thereby degrading the molecular chain structure of organic matter in the VOC waste gas into low-molecular compounds, thereby purifying the VOC waste gas.

[0029] The staggered design of the UV lamps 231 and the first catalyst carrier plate 241 ensures that the catalyst layer outside the first catalyst carrier plate 241 can be evenly illuminated, and the airflow can evenly pass through the photocatalytic component 2, ensuring uniform exhaust gas treatment capabilities.

[0030] Based on the above technical solution, when this treatment equipment treats exhaust gas, VOC exhaust gas is fed into treatment tower 1 through air inlet 11. The ultraviolet light and catalyst in the multi-layer photocatalytic assembly 2 work together to decompose organic matter in the exhaust gas, purifying the VOC exhaust gas. The design of the multi-layer photocatalytic assembly 2 greatly improves the purification rate of VOC exhaust gas and reduces the difficulty of further purification of the exhaust gas. Furthermore, the tower design also facilitates heat dissipation from the UV lamp assembly 23, ensuring stable operation of the treatment equipment.

[0031] In this technical solution, if Figure 1-5 As shown, the first catalyst supporting plate 241 is not parallel to the light path of the UV lamp 231. This ensures that the UV light can reach the surface of the first catalyst supporting plate 241, ensuring that the catalyst layer can be stably irradiated by the ultraviolet light, ensuring the stability of the catalytic oxidation process, and ensuring the purification capacity of the exhaust gas.

[0032] In this technical solution, if Figure 1-5 As shown, the first catalyst supporting plate 241 and the UV lamp 231 are both arranged vertically, which is consistent with the flow direction of the airflow in the tower body, ensuring a long contact time between the airflow and the catalyst layer, ensuring sufficient decomposition of organic matter in the VOC exhaust gas, and ensuring the purification rate of organic matter in the exhaust gas.

[0033] In this technical solution, if Figure 1-5 As shown, the front side of the purification drawer 21 is equipped with multiple handles 211 and a lifting hook 212. The sidewalls of the treatment tower 1 are provided with multiple mounting sleeves 13 for mounting the purification drawers 21. The inner walls of the mounting sleeves 13 are provided with a sealing layer. This facilitates installation of the purification drawer 21. When maintenance or replacement of the photocatalytic component 2 is required, the purification drawer 21 can be easily removed for cleaning or replacement, ensuring ease of use of the purification equipment.

[0034] In this technical solution, if Figure 2 As shown, a second catalyst support plate 25 is positioned beneath each layer of the photocatalytic assemblies 2. This second catalyst support plate 25 is provided with air holes extending therethrough for airflow. UV lamps 231 positioned beneath the second catalyst support plates 25 are also stimulated by ultraviolet light to catalyze oxidation, enhancing the treatment equipment's ability to decompose and purify organic waste gas, and improving the purification rate.

[0035] In this technical solution, if Figure 2 As shown, a flow equalizing plate 3 is provided below each of the second catalyst supporting plates 25. The airflow is uniformly passed through the second catalyst supporting plate 25 and the photocatalytic component 2, ensuring that the organic matter in the VOC exhaust gas can fully contact the catalyst layer and also ensuring the efficient treatment capability of the VOC exhaust gas.

[0036] In this technical solution, if Figure 1 and 2As shown, the air inlet 11 is provided at the upper portion of the treatment tower 1, and the exhaust port 12 is provided at the lower portion of the tower. An exhaust gas filter layer 4 is provided at the exhaust port 12. Exhaust gas passes through the treatment tower 1 from bottom to top. Due to the high density of VOC exhaust gas, this design facilitates control of the airflow velocity of the VOC exhaust gas. The flow velocity is adjusted according to the different VOC exhaust gas contents to ensure the treatment effect of the exhaust gas. The exhaust gas filter layer 4 is used to treat residual water mist and other exhaust gases in the exhaust gas, ensuring the safety of direct discharge or facilitating subsequent treatment.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
