[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] See Figure 1-3 As shown, a disinfection and filtration device for a cleanroom exhaust vent includes a ventilation duct 1. An exhaust port 2 and a connecting cover 4 are fixedly connected to the output and input ends of the ventilation duct 1, respectively. An air inlet assembly 3 is embedded in the input end of the ventilation duct 1. A first conveying cover 5 is fixedly connected to the output end of the air inlet assembly 3. A disinfection water tank 6 is fixedly connected to the bottom end of the ventilation duct 1. A second conveying cover 7 is fixedly connected to one end of the disinfection water tank 6. A disinfection chamber 8 is fixedly connected to the inner end of the exhaust port 2. The disinfection chamber 8 is also fixedly connected to the second conveying cover 7. A matching mounting plate 9 and a replenishment water tank 10 are fixedly connected inside the output end of the ventilation duct 1. A connecting pipe 11 is fixedly connected to the bottom end of the replenishment water tank 10. A fixed mounting plate 12 and an adsorption filter plate 13 are embedded in the disinfection water tank 6. The connecting pipe 11 is also connected to the mounting plate 12. The air inlet assembly 3 includes an air inlet pipe 14, an internal interception filter plate 15, and a disinfection lamp tube 16. A circuit box 17 connected to the outside of the ventilation duct 1 is provided on the outside of the disinfection lamp tube 16.

[0029] In this embodiment of the utility model, the disinfection chamber 8 is trapezoidal and fixedly connected to the inner end of the exhaust port 2. The disinfection chamber 8 and the exhaust port 2 are connected in communication. The disinfection chamber 8 is a plasma disinfection chamber with a built-in plasma generator and an exhaust fan mechanism. The bottom end of the disinfection chamber 8 is connected in communication with the second conveying cover 7. The second conveying cover 7 is located at the bottom of the ventilation duct 1. The gas conveyed by the second conveying cover 7 is decomposed and disinfected through the disinfection chamber 8. The gas that has been disinfected by the disinfection water tank 6 is conveyed through the second conveying cover 7.

[0030] In actual use, the gas treated by the disinfection tank 6 is transported to the disinfection chamber 8 through the second conveying cover 7. The plasma generator built into the disinfection chamber 8 is activated to generate a plasma electrostatic field, which then decomposes and breaks down the bacteria in the gas, thus achieving a disinfection effect.

[0031] The disinfection tank 6 is a rectangular box protruding from the center. Its top end is connected to the air inlet assembly 3 via the first conveying cover 5, and its bottom end is connected to the disinfection chamber 8 via the second conveying cover 7. The mounting plate 12 and the adsorption filter plate 13 are arranged horizontally and are aligned with each other. Their side sections are arranged in an "L" shape. The mounting plate 12 is filled with a sponge layer, which is also connected to the adsorption filter plate 13. Multiple sets of adsorption filter plates 13 are vertically stacked in the disinfection tank 6, and their surfaces are arranged in a honeycomb pattern. The top of the replenishment tank 10 is connected to an addition pipe, and two sets of connecting pipes 11 are vertically arranged. The connecting pipes 11 have built-in valve mechanisms and are vertically embedded in the mounting plate 12. The replenishment tank 10 and the connecting pipes 11 achieve the effect of conveying disinfectant to the mounting plate 12 and the adsorption filter plate 13. The mounting plate 12, in conjunction with the adsorption filter plate 13, achieves the effect of adsorbing and storing disinfectant, and at the same time, it achieves the effect of adsorbing and disinfecting the gas passing through the disinfection tank 6. The disinfection tank 6 achieves the effect of transferring and storing gas.

[0032] In actual use, external gas is conveyed to the disinfection tank 6 through the first conveying hood 5. The gas passes vertically through multiple sets of adsorption filter plates 13 in sequence. The adsorption filter plates 13 adsorb bacteria and particles in the gas. The treated gas is then output through the second conveying hood 7. During this process, the disinfectant in the replenishment tank 10 is conveyed to the inside of the mounting plate 12 through the connecting pipe 11. The sponge layer inside the mounting plate 12 adsorbs the disinfectant until the disinfectant passes through the adsorption filter plates 13. When the gas passes through the adsorption filter plates 13, the adsorption filter plates 13 work together with the adsorbed disinfectant to achieve disinfection and sterilization of the gas.

[0033] The air inlet duct 14 is trapezoidal in shape, the connecting cover 4 is trapezoidal and outwardly flared, the intercepting filter plate 15 is vertically embedded in the air inlet duct 14, and multiple sets are arranged at equal intervals. The bottom of the inner end of the air inlet duct 14 is set as the output end, which is connected to the first conveying cover 5. The first conveying cover 5 is curved in an arc shape. The disinfection lamp tube 16 is an ultraviolet disinfection lamp, which is embedded in the inclined surface of the inner end of the air inlet duct 14, and multiple sets are arranged. The disinfection lamp tube 16 is also inclined and opposite to the intercepting filter plate 15. The disinfection lamp tube 16 achieves the effect of disinfecting and sterilizing the gas that initially enters the ventilation duct 1.

[0034] External gas enters the air inlet pipe 14 through the connecting cover 4, and passes through the interception filter plate 15 to intercept and filter particulate impurities. Finally, it is output to the first conveying cover 5 through the output end at the bottom of the inner end of the air inlet pipe 14. During this process, the disinfection lamp tube 16 disinfects and sterilizes the gas.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
