Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waste gas cylinder processing device, especially to a fluorine nitrogen mixed gas waste gas cylinder processing device. BACKGROUND

[0002] The fluorine nitrogen mixed gas cylinder is prone to rusting of the bottle valve during use, and the waste gas cylinder still contains varying amounts of fluorine nitrogen mixed gas, which is a highly toxic and strongly oxidizing substance, and has a significant safety hazard. If not properly handled, it may cause serious consequences such as safety accidents and environmental pollution, causing a significant negative impact on enterprises and society. Therefore, how to safely and effectively handle such waste gas cylinders has become a pressing problem.

[0003] The traditional processing method mainly includes the following steps: safely discharging residual gas, punching to release internal and external pressure balance, and recycling metal parts. However, these methods require that the bottle valve of the gas cylinder be intact, otherwise the processing cannot be performed. At the same time, punching to release pressure and disassembling the gas cylinder itself also pose a significant safety and environmental risk. If not handled properly, it can easily lead to accidents, causing personal injury and environmental pollution.

[0004] In summary, the traditional fluorine nitrogen mixed gas waste gas cylinder processing method has the problems of high safety risk and high operation risk, and it is difficult to meet the requirements of modern chemical production in terms of safety and environmental protection. SUMMARY

[0005] In view of the above problems, the present application aims to provide a safer and more reliable gas cylinder processing technology to ensure the safety of the operation process, reduce the risk of environmental pollution, and improve the processing efficiency, providing a more advanced solution for the relevant industry.

[0006] To achieve the above-mentioned purpose, the present application provides a fluorine nitrogen mixed gas waste gas cylinder processing device, comprising: a processing room and an operation room arranged adjacent to each other; the processing room and the operation room are separated by an explosion-proof wall;

[0007] The explosion-proof wall is provided with an exhaust hole and an operation hole, the exhaust hole is used to guide the gas in the processing room, and the exhaust hole is in communication with an exhaust pipe, one end of the exhaust pipe away from the exhaust hole is connected with a tail gas treatment tank; the operation hole is used to accommodate an operation wrench, the operation end of the operation wrench is placed in the processing room, and the other end of the operation wrench is placed in the operation room;

[0008] The processing room contains a gas cylinder fixing platform and a lift. The gas cylinder fixing platform is placed on the lift, and the lift is used to drive the gas cylinder fixing platform to move along the height direction so that the opening of the cylinder is aligned with the operating hole. The gas cylinder fixing platform is used to fix and accommodate the cylinder. When the cylinder is placed on the gas cylinder fixing platform, the opening of the cylinder extends beyond the operating room.

[0009] Unlike existing technologies, the above-mentioned technical solution isolates potential explosion risks during valve disassembly through an explosion-proof wall separating the processing room and the operating room, ensuring operator safety. The vents and exhaust pipes allow for the timely removal and purification of harmful gases generated during processing, preventing leakage into the operating room and the external environment, effectively reducing environmental pollution. This design also minimizes the risk of operator exposure to harmful gases, ensuring operational safety. Furthermore, the combined use of the cylinder fixing platform and elevator simplifies cylinder positioning and valve disassembly, allowing for easy adjustment of cylinder height to ensure proper alignment between the cylinder opening and the operating port, thus improving the efficiency of valve disassembly.

[0010] In some embodiments, a fluorine-nitrogen mixed gas waste cylinder treatment device further includes: a ventilation fan placed in the exhaust port to extract gas from the treatment room.

[0011] In some embodiments, the exhaust gas treatment tank includes: a treatment tank body, a feed port, and a drain port; the feed port is provided at the top of the treatment tank body, and the drain port is provided at the bottom of the side wall of the treatment tank body.

[0012] In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a wrench platform, the fixed platform being placed in the operating chamber, the fixed platform being used to support the operating end of the operating wrench.

[0013] In some embodiments, a fluorine-nitrogen mixed gas waste cylinder treatment device further includes: a cylinder valve fixing bracket, which is placed between the explosion-proof wall and the cylinder body fixing platform, and is used to fix the valve.

[0014] In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a circulation tank, a spray head, and a circulation pipeline. The circulation tank is located below the spray head, and both ends of the circulation pipeline are connected to the circulation tank and the spray head, respectively. The spray head is located above the connection between the cylinder body and the valve.

[0015] In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a pH detection device; the probe end of the pH detection device is placed in the circulation tank, and the pH detection device is used to detect the pH value in the circulation tank.

[0016] In some embodiments, a fluorine-nitrogen mixed gas waste cylinder treatment device further includes: a plurality of monitors, wherein the plurality of monitors are respectively placed in the operation room and the treatment room.

[0017] Unlike existing technologies, this invention significantly reduces the safety risks for operators during valve disassembly by separating the processing room and the operating room with an explosion-proof wall. The vent and operating ports on the explosion-proof wall allow for timely exhaust and purification of waste gas during processing, preventing the leakage of harmful gases and reducing pollution to the operating room and the external environment.

[0018] The combined use of the gas cylinder fixing platform and the lifting mechanism not only simplifies the positioning process of waste gas cylinders but also allows for precise adjustment of the cylinder height, aligning the cylinder opening with the operating port and thus improving the efficiency of valve disassembly. This design effectively enhances the safety and convenience of the entire operation, reducing the risk of accidents caused by improper operation.

[0019] The ventilation fan enables the device to actively extract waste gas from the treatment room, accelerating the discharge rate and ensuring that the treatment room maintains a low concentration of harmful gases, further reducing the risk of operator exposure to harmful gases. The combined use of the ventilation fan, exhaust pipe, and tail gas treatment tank enhances the exhaust gas removal and purification capabilities, ensuring efficient and environmentally friendly treatment processes.

[0020] Furthermore, the exhaust gas treatment tank of this device can effectively collect and treat the waste gas generated during the treatment process, preventing direct discharge into the environment. Multiple treatment units within the treatment tank, such as a packing layer and a spray system, improve the waste gas treatment efficiency and ensure that the final emitted gas meets environmental standards.

[0021] By introducing a pH detection device, the acidity or alkalinity of the liquid in the circulation tank is monitored in real time, ensuring the effectiveness of the reaction during the treatment process. The electrical connection between the controller and the monitor enables real-time analysis of the system's operating status, improving the level of intelligence in the treatment process. The monitor allows operators to have full control over the operation, ensuring adherence to operating procedures and timely detection of safety hazards. Furthermore, the wrench platform and bottle valve fixing bracket enhance the stability and reliability of the operation.

[0022] In summary, the fluorine-nitrogen mixed gas waste cylinder treatment device provided by this utility model effectively reduces operational risks, improves treatment efficiency, and provides a reliable guarantee for the safe and environmentally friendly treatment of waste.

[0043] Please see Figures 1 to 5 This embodiment provides a waste gas cylinder treatment device for fluorine-nitrogen mixed gas, characterized in that it includes: a treatment room 10 and an operation room 20 arranged adjacent to each other; the treatment room 10 and the operation room 20 are separated by an explosion-proof wall 30;

[0044] The explosion-proof wall 30 is provided with an exhaust hole 31 and an operating hole 32. The exhaust hole 31 is used to exhaust the gas in the processing room 10 and is connected to the exhaust pipe 40. The end of the exhaust pipe 40 away from the exhaust hole 31 is connected to the exhaust gas treatment tank 50. The operating hole 32 is used to accommodate an operating wrench 60. The operating end of the operating wrench 60 is placed in the processing room 10, and the other end of the operating wrench 60 is placed in the operating room 20.

[0045] The processing room 10 contains a gas cylinder fixing platform 70 and a lift 80. The gas cylinder fixing platform 70 is placed on the lift 80, which drives the gas cylinder fixing platform 70 to move along the height direction, aligning the opening of the cylinder body a with the operating hole 32. The gas cylinder fixing platform 70 is used to fix and accommodate the cylinder body a. When the cylinder body a is placed on the gas cylinder fixing platform 70, the opening of the cylinder body a extends beyond the processing room 20. Further, the waste gas cylinder includes a cylinder body a and a valve b, with the valve b detachably mounted on the cylinder body a.

[0046] In this embodiment, the processing room 10 and the operating room 20 are separated by an explosion-proof wall 30 to ensure the safety of operators. The explosion-proof wall 30 is equipped with an exhaust port 31 and an operating port 32, used to exhaust waste gas from the processing room 10 and to accommodate an operating wrench 60, respectively. In the specific operation process: First, the waste gas cylinder containing a fluorine-nitrogen mixture is placed on the cylinder fixing platform 70 and adjusted by the lift 80 to align with the operating port 32. Then, the valve b on the gas cylinder is removed using the operating wrench 60 located in the operating room 20. After removing valve b, the gas in the processing room 10 enters the exhaust pipe 40 through the exhaust port 31 and finally enters the exhaust gas treatment tank 50 for purification.

[0047] During the disassembly of valve b, the explosion-proof wall 30 between the processing room 10 and the operating room 20 isolates potential explosion risks, ensuring the safety of operators. The vent 31 and vent pipe 40 allow for the timely extraction and purification of harmful gases generated during the process, preventing leakage into the operating room 20 and the external environment, effectively reducing environmental pollution. This design also minimizes the risk of operator exposure to harmful gases, ensuring operational safety. Furthermore, the combined use of the gas cylinder fixing platform 70 and the elevator 80 simplifies the positioning of the gas cylinder and the disassembly of valve b, allowing for easy adjustment of the cylinder height to ensure proper alignment between the cylinder opening and the operating port 32, thus improving the efficiency of valve b disassembly.

[0048] Please see Figures 1 to 5 In some embodiments, a fluorine-nitrogen mixed gas waste cylinder treatment device further includes: a ventilation fan 90, which is placed in the exhaust port 31 to extract gas from the treatment room 10.

[0049] In this embodiment, the ventilation fan 90 is placed in the exhaust port 31 on the explosion-proof wall 30 to extract gas from the processing room 10, thereby further optimizing the gas discharge process. Specifically, during the disassembly of the gas cylinder valve b, a large amount of waste gas generated in the processing room 10 relies solely on natural diffusion, resulting in a slow discharge rate and increasing the risk of personnel exposure. By actively extracting the waste gas using the ventilation fan 90, the discharge rate can be effectively accelerated, ensuring that the processing room 10 is always maintained at a low concentration, effectively reducing the risk of personnel exposure to harmful gases and improving equipment safety. Simultaneously, the use of the ventilation fan 90 also helps improve the airflow throughout the processing room 10. Through directional extraction, good convection ventilation can be formed, preventing gas from accumulating in dead corners within the processing room 10 and improving the overall ventilation effect. Furthermore, the ventilation fan 90 can also be used in conjunction with the exhaust pipe 40 and the exhaust gas treatment tank 50 described later, further enhancing the effective exhaust and purification capabilities.

[0050] Please see Figures 1 to 5 In some embodiments, the exhaust gas treatment tank 50 includes: a treatment tank body 51, a feeding port 52, and a drain port 53; the feeding port 52 is provided at the top of the treatment tank body 51, and the drain port 53 is provided at the bottom of the side wall of the treatment tank body 51.

[0051] In this embodiment, the feeding port 52 at the top of the treatment tank body 51 is used to add adsorbent or chemical reagents into the treatment tank for further purification of the waste gas. The bottom of the side wall of the treatment tank body 51 is provided with a drain port 53 to facilitate the discharge of treated wastewater or solid waste, ensuring the continuity and efficiency of the treatment process.

[0052] In some embodiments, the treatment tank body 51 also generates waste gas during the process of treating the exhaust gas from the treatment room 10. This waste gas can be collected or treated by a waste treatment device, so the treatment tank body 51 is connected to the waste treatment device. This design not only enables centralized treatment of waste gas, but also allows the waste gas generated in the treatment tank to be collected and purified by the waste treatment device, avoiding direct discharge of waste gas into the environment, thereby reducing the risk of environmental pollution.

[0053] Furthermore, multiple treatment units, such as packing layers and spray devices, can be installed within the treatment tank body 51 to improve the treatment efficiency of the exhaust gas. After entering the treatment tank, the exhaust gas first reacts with the adsorbent in the packing layer to remove harmful components. Then, it undergoes wetting treatment by the spray device to further capture and eliminate residual pollutants. This series of treatment steps can effectively reduce the concentration of harmful substances in the exhaust gas, ensuring that the final emitted gas meets environmental protection standards.

[0054] In summary, this embodiment achieves efficient purification and management of waste gas generated during the treatment process by setting up the exhaust gas treatment tank 50 and connecting it to the waste treatment device. The design of the treatment tank enhances the centralization and systematic nature of waste gas treatment and provides multiple treatment methods to improve purification efficiency. This not only reduces the environmental impact of waste gas but also ensures the safety and reliability of the treatment process. In addition, the setting of the drain outlet 53 simplifies the discharge of wastewater and solid waste, improves operational convenience and work efficiency, and makes the entire waste gas cylinder treatment system more efficient and environmentally friendly.

[0055] Please see Figures 1 to 5 In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a wrench platform 100, the fixed platform being placed in the operating chamber, the fixed platform being used to support the operating end of the operating wrench 60.

[0056] In this embodiment, one end of the operating wrench 60 is located in the processing room 10, responsible for disassembling valve b on the gas cylinder, while the other end is located in the operating room 20 for convenient control and operation by the operator. To ensure the stability and reliability of the operating wrench 60 during use, a wrench platform 100 is provided in the operating room 20. The operator can place the operating end of the operating wrench 60 on this platform, which provides support for the wrench and prevents it from shaking or shifting during use, thus affecting the accuracy and safety of the disassembly operation.

[0057] Meanwhile, the wrench platform 100 also improves the ergonomics of operation. By reasonably adjusting the height and position of the platform, operators can maintain a more comfortable posture during operation, reducing the physical burden that may result from prolonged operation, alleviating the labor intensity of operators, and providing strong support for the smooth operation of the entire gas cylinder handling process.

[0058] Please see Figures 1 to 5 In some embodiments, a fluorine-nitrogen mixed gas waste cylinder treatment device further includes: a cylinder valve fixing bracket 110, which is placed between the explosion-proof wall 30 and the cylinder body a fixing platform, and the cylinder valve fixing bracket 110 is used to fix the valve b.

[0059] In this embodiment, the cylinder valve fixing bracket 110 is placed between the explosion-proof wall 30 and the cylinder body a fixing platform, forming a safe and functional working area. During the process, when the cylinder valve b needs to be disassembled, the fixing bracket firmly secures the valve b, preventing it from shaking or accidentally falling off during operation, thereby ensuring the safety and accuracy of the operation.

[0060] Furthermore, the design of the valve fixing bracket 110 takes into account the structural characteristics of valve b. The shape and size of the bracket are compatible with various types of valve b, making it suitable for gas cylinders of different specifications and models. This allows the processing device to be widely used in different gas cylinder processing scenarios. Simultaneously, the installation position of the fixing bracket optimizes the working space, ensuring that operators can easily access each operating part of valve b during disassembly without interference from other equipment or structures, further improving the operational efficiency of the entire waste gas cylinder processing system. In summary, by setting up the valve fixing bracket 110, the safety and stability of the gas cylinder valve b disassembly process are significantly improved.

[0061] Please see Figures 1 to 5 In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a circulation tank 120, a spray head 130, and a circulation pipeline 140. The circulation tank 120 is located below the spray head 130, and the two ends of the circulation pipeline 140 are respectively connected to the circulation tank 120 and the spray head 130. The spray head 130 is located above the connection between the cylinder body a and the valve b.

[0062] In this embodiment, the waste gas cylinder treatment device for fluorine-nitrogen mixed gas is equipped with a circulating spray system, including a circulating tank 120, a spray head 130 and a circulating pipeline 140, which further optimizes the waste gas treatment during the disassembly process of cylinder valve b.

[0063] Specifically, the circulation tank 120 is positioned below the spray head 130 and serves a collection function. When the valve b of the gas cylinder is disassembled, a large amount of waste gas containing a fluorine-nitrogen mixture is generated in the treatment room 10. This waste gas is first drawn into the spray head 130, during which the spray head 130 sprays a special adsorption liquid or chemical reagent solution into the waste gas. This solution can chemically react or physically adsorb the harmful components in the waste gas, thereby effectively removing pollutants from the waste gas.

[0064] The treated exhaust gas flows from the spray head 130 to the circulation tank 120, where it is collected. Then, the circulation pipe 140 returns the liquid from the circulation tank 120 to the spray head 130, forming a closed-loop circulation system. Furthermore, to ensure the stability and efficiency of the circulation process, a circulation pump is installed on the circulation pipe 140 to drive the continuous flow of liquid within the circulation system.

[0065] This circulating spray design maximizes the efficiency of waste gas treatment. On one hand, reusing the adsorption liquid or chemical reagents reduces the amount of consumables used and lowers operating costs. On the other hand, the circulating system ensures that pollutants in the waste gas are not left behind after a single treatment, but are continuously and effectively removed. This closed-loop circulation method minimizes the direct emission of harmful substances, thus significantly reducing environmental impact and achieving the recycling of resources and energy.

[0066] In addition, the spray head 130 is positioned above the connection between the gas cylinder valve b and the cylinder body a, which not only allows it to fully contact the exhaust gas generated during the disassembly of valve b, but also allows it to promptly detect any harmful substances that may leak from the connection, thus improving the safety of the entire treatment process.

[0067] Please see Figures 1 to 5 In some embodiments, a waste gas cylinder treatment device for fluorine-nitrogen mixed gas further includes: a pH detection device 150; the detection end of the pH detection device 150 is placed in the circulation tank 120, and the pH detection device 150 is used to detect the pH value in the circulation tank 120.

[0068] In this embodiment, pH value is an important indicator for measuring the acidity or alkalinity of a liquid, and it can intuitively reflect the reaction effect of the adsorbent liquid or chemical reagents used in the treatment process. By introducing a pH detection device 150, the waste gas cylinder treatment device for fluorine-nitrogen mixture provided in this embodiment can further improve the safety and effectiveness of the waste gas treatment process. Specifically, the pH detection device 150 can continuously monitor the state of the liquid in the circulation tank 120 to ensure that it operates within the optimal acid-base range. When the cylinder valve b is disassembled, the adsorbent liquid sprayed by the spray head 130 reacts with the harmful components in the waste gas, and the efficiency of this reaction is affected by the pH value. By monitoring the pH value in real time, the system can issue an alarm in a timely manner or automatically adjust the liquid composition when the pH value deviates from the preset range. For example, if the pH value is too low, it may mean that the liquid is too acidic. At this time, it can be adjusted by adding alkaline substances to ensure the stability of the treatment effect. At the same time, the setting of the pH detection device 150 can also help operators judge the service life and effectiveness of the adsorbent liquid, thereby improving the reliability of the entire treatment process.

[0069] In summary, real-time pH monitoring ensures that the liquid in the circulation tank 120 remains under optimal reaction conditions, thereby improving the efficiency of waste gas treatment. Furthermore, timely adjustment of the liquid's acidity or alkalinity not only optimizes the chemical reaction process but also reduces potential byproducts and waste generated during treatment, further protecting the environment. This intelligent monitoring method provides crucial assurance for the safe and stable operation of the fluorine-nitrogen mixed gas waste cylinder treatment device.

[0070] Please see Figures 1 to 5 In some embodiments, a waste gas cylinder treatment device for a fluorine-nitrogen mixture further includes multiple monitors 160, which are respectively placed in the operation room 20 and the treatment room 10. The purpose of the monitors 160 is to comprehensively monitor and record various key parameters and status information during the cylinder treatment process. Within the operation room 20, the monitors 160 can monitor the operators' work in real time, ensuring they strictly adhere to operating procedures and take necessary protective measures. Simultaneously, the monitors 160 can also detect any possible abnormalities, such as operational errors or equipment malfunctions, and issue timely alarms to ensure operational safety.

[0071] Inside processing room 10, monitors 160 focus on the operational status of the gas processing unit. They can collect real-time data on temperature, humidity, and gas concentration within processing room 10, providing a basis for subsequent data analysis and fault diagnosis. For example, if monitoring data shows that the concentration of the fluorine-nitrogen mixture in processing room 10 exceeds the standard, the control system can immediately take measures, such as activating the emergency exhaust system, to prevent accidents. Simultaneously, the monitoring data can also be used to optimize the processing technology and improve the overall system efficiency.

[0072] In some embodiments, a controller is also included, which is electrically connected to the pH detection device 150 and the monitor 160 for real-time monitoring of the conditions in the operating room 20 and the processing room 10; and simultaneously detecting the pH value of the water in the circulation tank 120.

[0073] In this embodiment, to achieve centralized control of the entire processing process, the processing device is also equipped with a controller. This controller is electrically connected to the pH detection device 150 and various monitors 160, enabling it to receive and integrate various monitoring data in real time. Based on the monitoring data, the controller can intelligently analyze the current operating status of the system and automatically adjust key parameters. For example, if the pH value of the solution in the circulation tank 120 deviates from the optimal range, the controller will promptly issue an adjustment command to ensure the stability of the processing effect.

[0074] Simultaneously, the controller can record and store monitoring data, forming detailed operation logs. This data not only aids in post-process analysis and optimization but also provides reliable evidence for relevant departments, ensuring the compliance and traceability of the entire process. Furthermore, the controller can interface with remote monitoring systems to achieve real-time remote monitoring and operation and maintenance management of the processing equipment.

[0075] Furthermore, the following example can be derived from the above scheme:

[0076] This utility model constructs a treatment room 10 and an operating room 20, which are separated by an explosion-proof wall 30. A device for treating waste fluorine-nitrogen mixed gas, as well as various gas cylinders such as liquefied hydrogen chloride and liquefied hydrogen bromide, includes a special device for disassembling gas cylinder valves (including a circulation tank 120, spray heads 130, circulation pipelines 140, a gas cylinder fixing platform 70, a lift 80, an operating wrench 60, and a wrench platform 100, etc.), a monitor 160 for the treatment room 10 (including a monitoring probe, a main unit, a display, etc.), a pH detection device 150 (including an online monitoring probe and an instrument display screen), and a tail gas treatment tank 50 (including a ventilation fan 90, a treatment tank body 51, and related pipelines).

[0077] The processing room 10 is equipped with a gas cylinder fixing platform 70, and a lift 80 is installed under the gas cylinder fixing platform 70, which can handle gas cylinders of different diameters (40-50)L.

[0078] The control room 20 is equipped with equipment controllers (including switches and tension buttons for ventilation fans 90, circulating pumps, operating wrenches 60, etc.), a display screen for the pH detection device 150, and a monitoring monitor.

[0079] The special device for disassembling gas cylinder valves is located at one end in the waste gas cylinder processing room 10 and at the other end in the operating room 20. Personnel in the operating room 20 can observe through the monitoring display and use the operating wrench 60 to loosen and remove valve b. This prevents the gaseous or liquid phases of the fluorine-nitrogen mixture from splashing during the replacement process, and also prevents injuries from explosions.

[0080] The circulating liquid and tail gas absorption liquid used in this patent are both sodium hydroxide (NaOH) solutions. Potassium hydroxide (KOH) solutions must not be used because their waste liquid cannot be treated after being discharged into the sewage treatment plant, resulting in excessive emissions.

[0081] Furthermore, the processing steps of this utility model are as follows:

[0082] 1. The gas cylinders were transferred to processing room 10 using a forklift;

[0083] 2. Manually place the gas cylinder onto the gas cylinder fixing platform 70, and use the gas cylinder valve removal device to fix the gas cylinder valve b.

[0084] 3. Close the door of processing room 10 and turn on the ventilation fan 90.

[0085] 4. Turn on the circulation pump and confirm that the circulating liquid spray is operating normally.

[0091] The combined use of the gas cylinder fixing platform 70 and the lifting platform 80 not only simplifies the positioning process of the waste gas cylinder but also allows for precise adjustment of the cylinder's height, aligning the cylinder opening with the operating port 32, thereby improving the efficiency of valve b disassembly. This design effectively enhances the safety and convenience of the entire operation, reducing the risk of accidents caused by improper operation.

[0092] The ventilation fan 90 enables the device to actively extract waste gas from the treatment room 10, accelerating the discharge speed and ensuring that the treatment room 10 maintains a low concentration of harmful gases, further reducing the risk of operators being exposed to harmful gases. The combined use of the ventilation fan 90, exhaust pipe 40, and tail gas treatment tank 50 enhances the exhaust gas removal and purification capabilities, ensuring efficient and environmentally friendly processing.

[0093] Furthermore, the exhaust gas treatment tank 50 of this device can effectively collect and treat the waste gas generated during the treatment process, preventing direct discharge into the environment. Multiple treatment units, such as a packing layer and a spray device, are installed within the treatment tank body 51, improving the waste gas treatment efficiency and ensuring that the final emitted gas meets environmental standards.

[0094] By introducing a pH detection device 150, the acidity or alkalinity of the liquid in the circulation tank 120 is monitored in real time, ensuring the reaction effect during the treatment process. The electrical connection between the controller and the monitor 160 enables real-time analysis of the system's operating status, improving the intelligence level of the treatment process. The monitor 160 allows operators to monitor the entire operation, ensuring adherence to operating procedures and timely detection of safety hazards. Furthermore, the wrench platform 100 and the bottle valve fixing bracket 110 enhance the stability and reliability of the operation.

[0095] In summary, the fluorine-nitrogen mixed gas waste cylinder treatment device provided by this utility model effectively reduces operational risks, improves treatment efficiency, and provides a reliable guarantee for the safe and environmentally friendly treatment of waste.
