Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically to a medical wastewater ozone sterilization tail gas treatment device. Background Technology

[0002] Ozone sterilization is a commonly used and highly efficient disinfection method in the treatment of medical wastewater. Ozone has strong oxidizing properties and can quickly kill various bacteria, viruses and pathogens in wastewater, effectively reducing the risk of pollution to the environment from medical wastewater. However, the exhaust gas discharged after ozone sterilization still contains a certain concentration of ozone and may carry volatile organic compounds, harmful microorganisms and other pollutants. Excessive emissions may have adverse effects on the surrounding air quality and ecosystem.

[0003] Currently, some simple ozone sterilization exhaust gas treatment devices for medical wastewater only use activated carbon adsorption to remove ozone from the exhaust gas. However, activated carbon has a limited adsorption capacity, requires frequent replacement, and is not effective in removing volatile organic compounds and harmful microorganisms. Some traditional devices are not structurally reasonable, resulting in a short residence time of gas within the device, leading to insufficient treatment and exhaust gas emissions that fail to meet stringent environmental standards. Therefore, this paper proposes an ozone sterilization exhaust gas treatment device for medical wastewater to address the aforementioned problems. Utility Model Content

Furthermore, some traditional devices have unreasonable structural designs, resulting in short gas residence time within the device, leading to insufficient treatment and difficulty in meeting stringent environmental protection standards for tail gas emissions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figures 1-6 As shown, a medical wastewater ozone sterilization tail gas treatment device includes a catalytic decomposition box 1, an adsorption filter box 2, and an ultraviolet disinfection box 3. Both the catalytic decomposition box 1 and the adsorption filter box 2 have slots 4 at their front ends. The catalytic decomposition box 1 has one slot 4, and the adsorption filter box 2 has three slots 4. Guide grooves 5 are provided at both ends of the four slots 4. A fixing frame 6 is inserted into the inside of each slot 4. Guide strips 7 are fixedly connected to both ends of the fixing frame 6, and the guide strips 7 are inserted into the guide grooves 5. A catalytic decomposition box 3 is fixedly connected to the inner side of the right fixing frame 6. The catalytic decomposition module 103 is fixedly connected to the lower end of the catalytic decomposition module 103. The fixed frame 101 is fixedly connected to several evenly distributed heating resistance wires 102. The inner sides of the three fixed frames 6 on the left are fixedly connected from bottom to top to a primary filter layer 201, an activated carbon adsorption layer 202, and a high-efficiency filter layer 203. The ultraviolet disinfection box 3 is fixedly connected to a disinfection pipe 301. The inner walls of the front and rear sides of the ultraviolet disinfection box 3 are fixedly connected to several evenly distributed ultraviolet lamps 302.

[0028] Furthermore, the catalytic decomposition module 103 is honeycomb-shaped, made of alumina, and coated with manganese oxide on its surface.

[0029] Furthermore, the heating resistance wire 102 is used to generate heat, causing the residual ozone in the exhaust gas to decompose. The catalytic decomposition module 103 is made of alumina and coated with manganese oxide. The alumina acts as a support to support the manganese oxide, which in turn acts as a catalyst to promote the decomposition of ozone. The catalytic effect of manganese allows ozone to decompose rapidly into oxygen at a lower temperature, accelerating the decomposition rate of ozone. Moreover, manganese usually undergoes a redox reaction in the reaction, catalyzing the decomposition of ozone without being consumed, thus having a continuous catalytic effect.

[0030] Furthermore, the primary filter layer 201 is made of fiber mesh, such as glass fiber or polyester fiber, which can filter larger particulate impurities in the exhaust gas, such as dust and particulate matter, protecting the subsequent activated carbon adsorption layer 202 and high-efficiency filter layer 203 and extending their service life. The activated carbon adsorption layer 202 is filled with granular activated carbon, which has a huge specific surface area and rich microporous structure. Installed above the primary filter layer 201, it can adsorb volatile organic compounds and some residual ozone in the exhaust gas, further purifying the exhaust gas and reducing the concentration of pollutants. The high-efficiency filter layer 203 is composed of several polytetrafluoroethylene membrane filter elements evenly arranged, which can filter tiny particles and microorganisms in the exhaust gas, ensuring that the exhaust gas after adsorption and filtration reaches a high purification standard.

[0031] Furthermore, the ultraviolet lamp 302 is fixed to the front and rear inner walls of the ultraviolet disinfection box 3, and can emit ultraviolet light to destroy the DNA or RNA structure of harmful microorganisms, causing them to lose their activity, thereby disinfecting and sterilizing the exhaust gas that has been adsorbed and filtered.

[0032] Furthermore, the disinfection pipe 301 is a serpentine glass pipe. The serpentine structure increases the residence time of the exhaust gas in the pipe, allowing the exhaust gas to be fully exposed to ultraviolet radiation, thereby improving the disinfection and sterilization effect.

[0033] Furthermore, a gas conveying hood 9 is fixedly connected to the bottom inner side of both the catalytic decomposition box 1 and the adsorption filter box 2, and a gas collecting hood 10 is fixedly connected to the top of both the catalytic decomposition box 1 and the adsorption filter box 2.

[0034] Furthermore, an air inlet pipe 11 is fixedly connected to the right end of the catalytic decomposition box 1. One end of the air inlet pipe 11 passes through the right end of the catalytic decomposition box 1 and is fixedly connected to the lower end of the right gas supply hood 9. The upper end of the right gas collection hood 10 is threadedly connected to a first delivery pipe 12. The other end of the first delivery pipe 12 passes through the right end of the adsorption filter box 2 and is fixedly connected to the lower end of the left gas supply hood 9. The upper end of the left gas collection hood 10 is threadedly connected to a second delivery pipe 13. The other end of the second delivery pipe 13 passes through the upper end of the ultraviolet disinfection box 3 and is fixedly connected to one end of the disinfection pipe 301. An exhaust pipe 14 is fixedly connected to the left end of the ultraviolet disinfection box 3. One end of the exhaust pipe 14 passes through the left end of the ultraviolet disinfection box 3 and is fixedly connected to the end of the disinfection pipe 301 away from the second delivery pipe 13.

[0035] Furthermore, the gas conveying hood 9 is fixed to the inner bottom of the catalytic decomposition box 1 and the adsorption filter box 2, which evenly disperses the exhaust gas entering the box, allowing it to fully contact the catalytic decomposition module 103 or the filter layer, thereby improving the treatment efficiency. The gas collecting hood 10 is fixed to the upper end of the catalytic decomposition box 1 and the adsorption filter box 2, which collects the treated exhaust gas and transports it to the next treatment stage through connecting pipes. One end of the air inlet pipe 11 is fixed to the right end of the catalytic decomposition box 1, and the other end is connected to the exhaust gas outlet of the medical wastewater ozone sterilization equipment, introducing the ozone-sterilized exhaust gas into the catalytic decomposition box 1. One end of the first conveying pipe 12 is threaded to the catalytic decomposition module 103. The gas collection hood 10 of box 1 passes through the right end of adsorption filter box 2 and is connected to the gas conveying hood 9 of adsorption filter box 2. It is used to transport the exhaust gas after catalytic decomposition and ensure that the gas smoothly enters adsorption filter box 2 from catalytic decomposition box 1. One end of the second conveying pipe 13 is threaded to the gas collection hood 10 of adsorption filter box 2, and the other end passes through the upper end of ultraviolet disinfection box 3 and is connected to the disinfection pipe 301. It transports the exhaust gas after adsorption and filtration to ultraviolet disinfection box 3 for disinfection treatment. One end of the exhaust pipe 14 is fixed to the left end of ultraviolet disinfection box 3, and the other end is connected to the outside, so as to discharge the purified exhaust gas after disinfection treatment into the atmosphere.

[0036] Furthermore, a handle 8 is fixedly connected to the front end of the fixed frame 6. The fixed frame 6 is fixed by plugging. By applying a certain external force to pull the handle 8 outward, it can be pulled out, which facilitates the replacement of the catalytic decomposition module 103, the primary filter layer 201, the activated carbon adsorption layer 202, and the high-efficiency filter layer 203. A rubber sealing gasket is provided at the connection between the fixed frame 6 and the slot 4 to ensure the sealing of the catalytic decomposition box 1 and the adsorption filter box 2 and prevent exhaust gas leakage.

[0037] Working principle: The exhaust gas from ozone sterilization of medical wastewater enters the catalytic decomposition box 1 through the inlet pipe 11. After being evenly dispersed by the gas conveying hood 9, the heating resistance wire 102 is energized and heats up, causing the residual ozone in the exhaust gas to decompose. The heated exhaust gas then passes upward through the catalytic decomposition module 103. Under the action of the catalytic decomposition module 103, the decomposition speed is relatively fast, and the ozone in the exhaust gas is decomposed into oxygen. The exhaust gas after catalytic decomposition is collected by the right-side gas collection hood 10 and enters the adsorption filter box 2 through the first conveying pipe 12. The exhaust gas then passes through the gas conveying hood 9. After being evenly dispersed, the exhaust gas passes through a primary filter layer 201, an activated carbon adsorption layer 202, and a high-efficiency filter layer 203 in sequence to remove particulate impurities, volatile organic compounds, and some harmful microorganisms. The exhaust gas after adsorption and filtration is collected by the left-side gas collection hood 10 and enters the disinfection pipe 301 of the ultraviolet disinfection box 3 through the second delivery pipe 13. Inside the disinfection pipe 301, the exhaust gas is irradiated by ultraviolet light emitted by the ultraviolet lamp tube 302, and the remaining harmful microorganisms are killed. Finally, the purified exhaust gas is discharged into the atmosphere through the exhaust pipe 14.
