Description

Technical Field

[0001] This utility model relates to the field of combustion chamber oxygen content detection technology, and more specifically, to a device for detecting the stable oxygen content in a carbon material combustion chamber. Background Technology

[0002] The oxygen content detection device for carbon material combustion chambers is a key piece of equipment specifically designed for real-time and accurate monitoring and control of oxygen concentration in the combustion chamber of carbon materials (such as graphite, carbon fiber, activated carbon, etc.) during high-temperature combustion or heat treatment. It continuously collects oxygen partial pressure or concentration signals in the combustion chamber atmosphere through a zirconia analyzer and transmits the data to the control system in real time. The core function of this device is to ensure that the oxygen content is maintained within the optimal stable range set by the process. This prevents excessive oxygen content from causing excessive oxidation and burn-off of carbon materials, quality degradation, or even equipment damage, while also avoiding insufficient combustion, increased energy consumption, and excessive emissions of harmful gases (such as carbon monoxide) caused by excessively low oxygen content. This ensures the efficient, safe, and stable operation of the carbon material processing process and the quality of the products.

[0003] Currently, the traditional extractive zirconia analyzers in use have sampling probes that cannot withstand high temperatures, and the jet pumps are prone to clogging, resulting in frequent damage to the zirconia head. In contrast, the direct-insertion zirconia analyzers cannot withstand high temperatures, and the probes are easily damaged and susceptible to fluctuations in operating conditions.

[0004] In summary, to improve service life and detection accuracy, it is necessary to address the issues of poor sampling stability and short service life. This can be achieved by lowering the ambient temperature of the core detection components of the instrument, thus extending service life. Furthermore, the jet pump should be indirectly in contact with the medium, minimizing the impact of the medium on the jet pump and ensuring more stable sampling. Utility Model Content

[0005] The present invention provides a carbon material combustion chamber oxygen content stability detection device, which aims to solve the problems of poor sampling stability, short service life and high maintenance cost in high-temperature, high-humidity, high-corrosion and high-dust combustion chamber flue gas environments caused by the sampling probe being not resistant to high temperature, the jet pump being prone to clogging and the zirconium head being easily damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon material combustion chamber oxygen content stability detection device, comprising a primary settling pipe, a detection instrument mounted on the surface of the primary settling pipe, a first fixed flange mounted on the outside of the detection instrument, the first fixed flange being fixedly connected to the primary settling pipe, a high-pressure exhaust pipe mounted on the surface of the primary settling pipe, a secondary settling tank mounted at the lower end of the high-pressure exhaust pipe, an exhaust pipe mounted at the upper end of the secondary settling tank, a jet pump mounted at the output end of the exhaust pipe, a purification mechanism provided on the primary settling pipe, and a waste removal mechanism provided on the secondary settling tank.

[0007] In a preferred embodiment, the connection end of the purification mechanism is connected to the primary settling pipe. The purification mechanism is used to purify the flue gas in the combustion chamber. The purification mechanism includes a coarse filter component and a fine filter component. The connection end of the coarse filter component is connected to the primary settling pipe, and the coarse filter component is used to filter large particulate matter in the flue gas. The connection end of the fine filter component is connected to the primary settling pipe, and the fine filter component is used to filter small particulate matter in the flue gas.

[0008] In a preferred embodiment, the coarse filtration assembly includes a second fixed flange mounted on the outside of the primary settling pipe, a sealing gasket mounted on the surface of the second fixed flange, a filter cover mounted on the outside of the primary settling pipe, an inner filter frame mounted inside the filter cover, and an inner filter screen mounted inside the inner filter frame.

[0009] In a preferred embodiment, the fine filtration assembly includes a plurality of in-tube filter frames equidistantly installed inside the primary settling pipe and an in-tube filter screen installed inside the in-tube filter frames.

[0010] In a preferred embodiment, the output end of the impurity removal mechanism is connected to the secondary settling tank. The impurity removal mechanism is used to filter and discharge water-soluble dust from corrosive media. The impurity removal mechanism includes a settling filter assembly and a waste liquid discharge assembly. The connection end of the settling filter assembly is connected to the secondary settling tank. The settling filter assembly is used to filter water-soluble dust from corrosive media. The output end of the waste liquid discharge assembly is connected to the settling filter assembly. The waste liquid discharge assembly is used to discharge waste liquid.

[0011] In a preferred embodiment, the settling and filtration assembly includes a plurality of in-tank filter frames equidistantly installed inside the secondary settling tank, an in-tank filter screen installed inside the in-tank filter frames, and an infusion pipe installed at the lower end of the secondary settling tank.

[0012] In a preferred embodiment, the waste liquid discharge assembly includes a discharge tank installed at the lower end of the infusion tube and a waste liquid discharge pipe installed at the lower end of the discharge tank.

[0013] In a preferred embodiment, a plurality of heat dissipation fins are equidistantly installed on the outer side of the first fixed flange, and an exhaust port is installed at the lower end of the jet pump.

[0014] The beneficial effects of this utility model are as follows: The core detection component of this instrument is located in a low-temperature environment. The medium will settle and cool down when passing through the primary settling pipe, thus improving its service life. The jet pump is in indirect contact with the medium, so the medium has less impact on the jet pump. The sampling is more stable, the sampling volume is smaller, the sample processing volume is smaller, the maintenance cycle is extended, the instrument detection medium is cleaner, and the impact on the instrument zircon head, filter, etc. is less, thus extending the replacement cycle of the instrument's core components.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 A device for detecting the stability of oxygen content in a carbon material combustion chamber includes a primary settling pipe 1, a detection instrument 11 mounted on the surface of the primary settling pipe 1, a first fixed flange 12 mounted on the outside of the detection instrument 11, the first fixed flange 12 being fixedly connected to the primary settling pipe 1, a high-pressure exhaust pipe 14 mounted on the surface of the primary settling pipe 1, a secondary settling tank 15 mounted at the lower end of the high-pressure exhaust pipe 14, an exhaust pipe 16 mounted at the upper end of the secondary settling tank 15, a jet pump 17 mounted at the output end of the exhaust pipe 16, a purification mechanism on the primary settling pipe 1, and a waste removal mechanism on the secondary settling tank 15.

[0023] It should be noted that the claim defines the core components of the device, including a primary settling pipe 1 for preliminary treatment of flue gas settling and cooling, on which a core detection component, a detection instrument 11, is installed; a high-pressure exhaust pipe 14 introduces the primary treated flue gas into a secondary settling tank 15 for further treatment; an exhaust pipe 16 and a jet pump 17 are used to extract and discharge the secondary treated clean gas; and the purification mechanism and the impurity removal mechanism are key components for treating solid impurities and liquid and dissolved impurities in the flue gas, respectively.

[0024] It is worth noting that the key to this structural design lies in the staged treatment. The primary settling pipe 1 directly faces the high-temperature and high-dust flue gas, which is initially cooled and large particles settle. The detection instrument 11 is installed here. The ambient temperature is already significantly lower than that at the combustion chamber outlet. The flue gas then enters the secondary settling tank 15, which is located at a lower position, for deep purification. Finally, it is extracted and discharged by the jet pump 17, which effectively protects the jet pump 17 and the detection instrument 11, and improves stability and lifespan.

[0025] Refer to the instruction manual appendix Figure 2 Image to Figure 3 The purification mechanism is connected to the primary settling pipe 1. The purification mechanism is used to purify the flue gas in the combustion chamber. The purification mechanism includes a coarse filter component and a fine filter component. The coarse filter component is connected to the primary settling pipe 1 and is used to filter large particles in the flue gas. The fine filter component is connected to the primary settling pipe 1 and is used to filter small particles in the flue gas.

[0026] It should be noted that the purification unit's function is to purify the flue gas, and it is specifically divided into two sub-functional components: coarse filtration and fine filtration. Coarse filtration is mainly responsible for intercepting larger particles, while fine filtration is responsible for removing smaller particles.

[0027] Refer to the instruction manual appendix Figures 2 to 3 The coarse filter assembly includes a second fixed flange 211 installed on the outside of the primary settling pipe 1, a sealing gasket 212 installed on the surface of the second fixed flange 211, a filter cover 213 installed on the outside of the primary settling pipe 1, an inner filter frame 214 installed inside the filter cover 213, and an inner filter screen 215 installed inside the inner filter frame 214.

[0028] It should be noted that the primary settling pipe 1 is provided with an installation and sealing base by the second fixed flange 211, the sealing gasket 212 ensures the airtightness of the connection, the filter cover 213 constitutes the outer shell, and the filter frame 214 inside the cover is used to fix and support the filter screen 215 inside the cover, which is the core component for achieving the filtration of large particles.

[0029] Refer to the instruction manual appendix Figure 3The fine filtration assembly includes multiple in-pipe filter frames 221 that are equidistantly installed inside the primary settling pipe 1 and an in-pipe filter screen 222 installed inside the in-pipe filter frames 221.

[0030] It should be noted that the fine filter assembly consists of multiple pipe filter frames 221 that are equidistantly installed inside the primary settling pipe 1. Each frame is equipped with a pipe filter screen 222, which is responsible for removing fine particulate matter from the flue gas.

[0031] Refer to the instruction manual appendix Figure 5 The output end of the impurity removal mechanism is connected to the secondary settling tank 15. The impurity removal mechanism is used to filter and discharge water-soluble dust from corrosive media. The impurity removal mechanism includes a settling filter assembly and a waste liquid discharge assembly. The connection end of the settling filter assembly is connected to the secondary settling tank 15. The settling filter assembly is used to filter water-soluble dust from corrosive media. The output end of the waste liquid discharge assembly is connected to the settling filter assembly. The waste liquid discharge assembly is used to discharge waste liquid.

[0032] It should be noted that the function of the impurity removal mechanism is to treat and discharge corrosive media and dust dissolved in water in the flue gas. It consists of a sedimentation filter component and a waste liquid discharge component. The former is responsible for filtering and collecting liquid containing impurities, while the latter is responsible for discharging these waste liquids from the system.

[0033] It is worth noting that the impurity removal mechanism is specifically designed to treat wet impurities in flue gas. Its core is liquid-solid separation and directional discharge of waste liquid, which prevents corrosive liquids from accumulating in the system, corroding equipment or interfering with detection, and also prevents them from entering the jet pump 17.

[0034] Refer to the instruction manual appendix Figure 5 The settling and filtration assembly includes multiple in-tank filter frames 311 that are equidistantly installed inside the secondary settling tank 15, an in-tank filter screen 312 installed inside the in-tank filter frames 311, and an infusion pipe 313 installed at the lower end of the secondary settling tank 15.

[0035] It should be noted that the settling and filtration assembly includes multiple in-tank filter frames 311 installed inside the secondary settling tank 15, each frame containing an in-tank filter screen 312, and a liquid delivery pipe 313 at the bottom of the tank. The in-tank filter screen 312 is used to intercept solid impurities in the liquid, and the liquid delivery pipe 313 is used to guide the filtered liquid to the waste liquid discharge assembly.

[0036] Refer to the instruction manual appendix Figure 5 The waste liquid discharge assembly includes a discharge tank 321 installed at the lower end of the infusion pipe 313 and a waste liquid discharge pipe 322 installed at the lower end of the discharge tank 321.

[0037] It should be noted that the waste liquid discharge assembly consists of a discharge tank 321 connected to the lower end of the infusion pipe 313 and a waste liquid discharge pipe 322 installed at the lower end of the discharge tank 321. The discharge tank 321 receives waste liquid from the sedimentation and filtration assembly, while the waste liquid discharge pipe 322 is responsible for finally discharging the waste liquid.

[0038] Refer to the instruction manual appendix Figures 2 to 5 Multiple heat dissipation fins 13 are equidistantly installed on the outer side of the first fixed flange 12, and an exhaust port 18 is installed at the lower end of the jet pump 17.

[0039] It should be noted that multiple heat dissipation fins 13 are installed on the outside of the first fixed flange 12, and an exhaust port 18 is installed at the lower end of the jet pump 17. The design of the heat dissipation fins 13 significantly increases the heat dissipation surface area of ​​the first fixed flange 12 area, which helps to dissipate the heat near the installation area of ​​the detection instrument 11 into the environment more quickly, further reducing the operating ambient temperature of the core components of the detection instrument 11 and extending its life. The exhaust port 18 is installed at the exhaust port of the jet pump 17, which can effectively reduce the exhaust back pressure, prevent blockage caused by poor gas diffusion or the decrease in efficiency of the jet pump 17, and improve the smoothness and stability of the system exhaust.

[0040] Working principle: High-temperature flue gas first enters the primary settling pipe 1 for initial settling and cooling. At this time, the detection instrument 11 detects the oxygen content of the cooled flue gas. Subsequently, the flue gas enters the secondary settling tank 15 through the high exhaust pipe 14. Under the action of the filter screen 312 in the tank, it undergoes deep impurity removal. Dissolved corrosive media and dust form waste liquid. The waste liquid flows into the discharge tank 321 through the infusion pipe 313 and is finally discharged from the system through the waste liquid discharge pipe 322. The purified gas is driven by the jet pump 17 through the exhaust pipe 16 and discharged through the exhaust port 18. During this process, the heat dissipation fins 13 continuously dissipate heat to the area of ​​the first fixed flange 12, ensuring that the detection instrument 11 is in a low-temperature working environment. At the same time, the filter screen 215 inside the cover and the filter screen 222 inside the pipe in the primary settling pipe 1 respectively intercept large particles and fine dust, while the filter screen 312 inside the tank achieves liquid-solid separation, jointly ensuring the stable operation of the jet pump 17 and the detection instrument 11.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
