Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an ultraviolet light decomposition box. Background Art

[0002] Some waste gas will be generated in the process of drug production. In order to decompose the malodorous substances in the waste gas, the waste gas is generally decomposed by ultraviolet irradiation. However, since the waste gas will have a certain humidity during the production process, when the waste gas enters the ultraviolet photolysis box for decomposition, the moisture in the waste gas adheres to the inner wall of the reaction chamber of the ultraviolet photolysis box, causing the ultraviolet lamp in the ultraviolet photolysis box to short-circuit. In addition, since water droplets form and adhere to the surface of the ultraviolet lamp, it will affect the propagation of light, thereby affecting the decomposition effect of the waste gas.

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figure 1 as well as Figure 2 A UV light decomposition box includes a box body 1, an irradiation component 2, a cooling component 3 and a flow guide component 4; the flow guide component is arranged in the box body 1, and the inner cavity of the box body 1 forms a cooling cavity 11 and a decomposition cavity 12 which are arranged in sequence along the air inlet direction and are interconnected, and the irradiation component 2 is arranged in the decomposition cavity 12; the cooling component 3 is installed in the cooling cavity 11, so that the exhaust gas passes through the cooling component 3 and then passes through the flow guide component 4 to enter the decomposition cavity 12. Among them, the box body 1 has an air inlet arranged on the end face of the cooling cavity 11 and an air outlet arranged on the end face of the decomposition cavity 12.

[0030] It can be understood that the cooling component 3 is provided so that the moisture in the exhaust gas can be quickly condensed and attached to the cooling component 3 after being cooled by the cooling component 3, thereby achieving water removal, and the exhaust gas after water removal passes through the guide component 4 and enters the irradiation component 2 for decomposition. The guide component 4 is used to slow down the speed at which the exhaust gas enters the decomposition chamber 12, so that the exhaust gas can be fully condensed and dehydrated in the cooling component 3, thereby reducing the water content of the exhaust gas, avoiding the attachment of moisture to the irradiation component 2 and affecting the normal operation of the irradiation component 2, and improving the exhaust gas decomposition effect.

[0031] In some embodiments, the guide assembly 4 includes a first baffle 41, a second baffle 42, and a guide plate 43; the first baffle 41 and the second baffle 42 are staggered along the air intake direction, so that an air intake channel 44 connecting the cooling chamber 11 and the decomposition chamber 12 is formed between the first baffle 41 and the second baffle 42; the guide plate 43 is arranged opposite to the outlet of the air intake channel 44, and an obtuse angle α is formed between the guide plate 43 and the distribution direction of the air intake channel 44, and the guide plate 43 is connected to the first baffle 41. The first baffle 41 and the second baffle 42 are arranged to form the air intake channel 44, slow down the speed of the exhaust gas entering the decomposition chamber 12, and make the exhaust gas fully condensed and dehydrated, while the guide plate 43 is arranged to guide the exhaust gas, so that the exhaust gas moves toward the middle of the decomposition chamber 12, and then is fully irradiated by the irradiation assembly 2, thereby ensuring the exhaust gas decomposition effect. Preferably, the longer the length of the air intake channel 44 is or the smaller the width of the air intake channel 44 in the air intake direction is, the slower the speed at which the exhaust gas enters the decomposition chamber 12 is, and the better the cooling effect is.

[0032] In some embodiments, the obtuse angle is 120° to 150°. Preferably, the obtuse angle is 130°, 140°, 144° or 145°.

[0033] In some embodiments, the irradiation assembly 2 includes a plurality of ultraviolet light panels 21; the decomposition chamber 12 is sequentially provided with a plurality of ultraviolet light panels 21 in the air inlet direction, and the inner wall of the decomposition chamber 12 is sequentially provided with at least three ultraviolet light panels 21 in the circumferential direction of the decomposition chamber 12, so as to allow the exhaust gas to be fully irradiated by ultraviolet light and decomposed, thereby improving the exhaust gas decomposition effect. Preferably, the inner wall of the decomposition chamber 12 is sequentially provided with four ultraviolet light panels 21 in the circumferential direction of the decomposition chamber 12.

[0034] In some embodiments, the cooling assembly 3 includes a water-cooling circulation pipe 31 and a water collecting tank 32; the water collecting tank 32 is arranged at the bottom of the cooling chamber 11; the water-cooling circulation pipe 31 is installed in the cooling chamber 11 and arranged opposite to the water collecting tank 32; the water inlet end of the water-cooling circulation pipe 31 is used to connect with an external water source. One end of the water-cooling circulation pipe 31 is connected with an external water source, and the other end is connected with a drain pipe 33 to ensure the condensation and dehydration effect of the exhaust gas, and the water droplets condensed on the surface of the water-cooling circulation pipe 31 will fall into the water collecting tank 32 for collection, so as to avoid moisture flowing into the decomposition box and affecting the normal operation of the irradiation assembly 2. Specifically, the water inlet end and the drain end of the water-cooling circulation pipe 31 are both arranged through the top of the box body 1.

[0035] In some embodiments, the water collection tank 32 is connected to a drain pipe 33, and the water outlet of the drain pipe 33 passes through the box body 1 and is connected to the external space of the box body 1. The setting of the drain pipe 33 can discharge the collected water in time to reduce the humidity in the cooling chamber 11 and ensure the condensation effect.

[0036] In some embodiments, a valve 34 is installed at the water outlet of the drain pipe 33 for opening the valve 34 to drain water when drainage is required, thereby ensuring the sealing of the cooling chamber 11 and preventing exhaust gas from leaking out of the drain pipe 33 .

[0037] The working principle of the utility model is:

[0038] After the waste gas enters the cooling chamber 11 for condensation and water removal, it enters the decomposition chamber 12 from the water inlet channel and is irradiated with ultraviolet light by the irradiation component 2 to decompose the odorous substances in the waste gas. After the decomposition is completed, the waste gas is discharged from the decomposition chamber 12.
