Technical Field

[0001] This utility model relates to the field of deodorization equipment technology, and in particular to UV photocatalytic deodorization equipment. Background Technology

[0002] Malodorous gases are diverse in type and have a wide range of sources. They can cause varying degrees of toxicity to the human respiratory, digestive, cardiovascular, endocrine, and nervous systems. Aromatic compounds such as benzene, toluene, and styrene can also cause birth defects and cancer. All such waste gases need to be purified before being emitted.

[0003] Currently, there are many types of deodorization equipment on the market, such as activated carbon adsorption deodorization equipment and chemical spray deodorization equipment.

[0004] Activated carbon adsorption deodorization equipment has drawbacks such as limited adsorption capacity, easy saturation, and the need for frequent adsorbent replacement; chemical spray deodorization equipment not only carries the risk of secondary pollution, but also exhibits inconsistent treatment effects for different types of odor gases. With increasingly stringent requirements for air quality, developing a highly efficient, environmentally friendly, and sustainable deodorization device has become a top priority.

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1-4As shown, the UV photocatalytic deodorization equipment includes a housing 1, which has an air inlet 11 and an air outlet 12. The housing 1 is an integral metal frame structure, and the surface of the frame is covered with a corrosion-resistant metal sheet 13. A UV light generating device 3 and a catalytic mesh structure 34 are installed inside the housing 1. The exhaust gas that needs to be deodorized enters the interior of the housing 1 through the air inlet 11. The housing 1 is made of a corrosion-resistant metal sheet 13 to enhance the strength and corrosion resistance of the housing 1.

[0038] The casing 1 also houses a fan 14 and a support base 15 for mounting the fan 14. A damping rubber pad 16 is installed between the support base 15 and the casing 1 to reduce noise and vibration. The fan 14 is a centrifugal fan, and its outlet is fitted with a flexible connecting pipe made of acid- and alkali-resistant, high-temperature-resistant rubber. This flexible connecting pipe is connected to the outlet 12 of the casing 1. In this embodiment, external gas is drawn into the casing 1 through the inlet 11, and the treated gas is discharged from the outlet 12. The support base 15 is connected to the inner wall of the casing 1 via the damping rubber pad 16 to reduce vibration and noise generated during fan 14 operation.

[0039] A frame 2 is installed inside the casing 1. The frame 2 has a first mounting plate 21 and a second mounting plate 22 arranged in parallel at intervals. Coaxial mounting holes 23 are formed between the first mounting plate 21 and the second mounting plate 22. A sleeve pipe 24 for passing exhaust gas is installed between the first mounting plate 21 and the second mounting plate 22. An activated carbon adsorption layer 25 is arranged on the inner wall of the sleeve pipe 24. Under the action of the fan 14, the exhaust gas entering the casing 1 passes through the sleeve pipe 24 between the first mounting plate 21 and the second mounting plate 22. The activated carbon adsorption layer 25 inside the sleeve pipe 24 adsorbs some impurity particles, thus achieving the first filtration and preventing blockage of the catalytic mesh structure 34 when it subsequently passes through it, ensuring purification efficiency.

[0040] The exhaust gas passing through the sleeve 24 will pass through the UV light generating device 3. The UV light generating device 3 includes multiple UV lamps 31 arranged in an array. The UV light generating device 3 is located between the frame 2 and the catalytic mesh. The UV light generating device 3 includes a first lamp plate 32 and a second lamp plate 33 arranged in parallel at intervals. The UV lamps 31 are arranged between the first lamp plate 32 and the second lamp plate 33. The first lamp plate 32 and the second lamp plate 33 can guide the light emission direction of the UV lamps. Under the guidance of the first lamp plate 32 and the second lamp plate 33, the light emission direction of the UV lamps 31 will be towards the catalytic mesh structure 34, which facilitates the catalytic reaction with the catalytic mesh structure 34 and further improves the deodorization effect.

[0041] Specifically, the catalytic mesh structure 34 is positioned in the light emission direction of the UV light generating device 3; the catalytic mesh structure 34 has a layered structure, which includes a base layer 36 with a tightly interwoven mesh structure, a catalytic coating 37 coated on the surface of the base layer 36, and a noble metal support layer 38 located on the surface of the catalytic coating 37; an auxiliary adsorption layer 39 is provided on the side of the catalytic coating 37 near the gas outlet 12.

[0042] The catalytic mesh structure 34 features regular hexagonal mesh 35 with uniform mesh size, effectively optimizing gas flow efficiency and catalytic contact area. The base layer 36 maintains a stable structure even under harsh environments such as high temperature and high humidity, providing robust and reliable structural support for the catalytic mesh structure 34. The noble metal loading layer 38 achieves uniform loading. The auxiliary adsorption layer 39 efficiently adsorbs residual small-molecule odor substances and some incompletely decomposed intermediate products from the gas, further enhancing the purification effect. This achieves a synergistic effect between UV light and the catalytic mesh structure 34, efficiently decomposing odor gas molecules, resulting in significant deodorization without secondary pollution.

[0043] Preferably, the base layer 36 is a mesh structure woven from high-temperature and corrosion-resistant ceramic fibers using a weaving process. The base layer 36, formed into a tight mesh by a special weaving and sintering process, ensures that it maintains a stable structure even under harsh environments such as high temperature and high humidity, providing a solid and reliable structural support for the catalytic mesh structure 34. The base layer 36 is fixed to the housing 1 via a metal frame and mounting slots, achieving a stable installation of the catalytic mesh structure 34 within the housing 1.

[0044] A temperature sensor 43 is installed inside the housing 1, mounted on the inner wall of the housing 1 near the UV light generator 3, to monitor the internal temperature of the housing 1. A heat dissipation device 4 is also installed inside the housing 1, comprising heat dissipation fins 41 and a cooling fan 42. The heat dissipation fins 41 are tightly fitted to the UV light generator 3, and the cooling fan 42 is fixed inside the housing 1, with the airflow directed towards the heat dissipation fins 41. When the temperature exceeds 60℃, the heat dissipation device 4, consisting of the heat dissipation fins 41 and the cooling fan 42, is activated, and the speed of the cooling fan 42 is automatically adjusted by an intelligent temperature control system, effectively dissipating heat from the UV light generator 3.

[0045] Furthermore, a monitoring system is installed inside the housing 1. This system includes a gas composition sensor, a particulate matter sensor, and a humidity sensor, which are respectively installed on the inner wall of the housing 1 near the air inlet 11. This system is used to monitor the composition of odorous gases, particulate matter concentration, and humidity in the air at the air inlet 11 in real time, and transmits the monitoring data to the control system via a data transmission line. The control system is installed in a control box inside the housing 1, and the control box is made of fire-resistant and dustproof metal. The control system controls the UV light generator 3 and the fan 14, and automatically adjusts the equipment's operating parameters based on the gas concentration information detected by the gas detection device. The control system has remote communication capabilities, connecting to a mobile terminal via Wi-Fi or Bluetooth. Users can remotely monitor the equipment's operating status, set operating parameters, and receive equipment fault alarm information via a mobile app.

[0046] The housing 1 is equipped with an inspection door 44, which is connected to the housing 1 by a hinge structure 45. A magnetic sealing structure 46 is also provided between the inspection door 44 and the housing 1. This ensures the airtightness of the housing 1 and prevents exhaust gas from leaking from the inspection door 44.

[0047] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
