Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing equipment, and in particular to an oxygen analyzer installation structure for detecting flue gas in glass kilns. Background Technology

[0002] In the glass manufacturing process, the oxygen content of the furnace flue gas is an important process parameter that directly affects the melting and quality of the glass. Therefore, detecting the oxygen content of the furnace flue gas and adjusting the combustion process based on the detection results is an important technology in the glass manufacturing process.

[0003] The installation structure of an oxygen analyzer needs to take into account a variety of factors, such as the structure of the kiln, the flow characteristics of the flue gas, the working principle and performance requirements of the oxygen analyzer. Through reasonable design and installation, it can be ensured that the oxygen analyzer can accurately and stably measure the oxygen content of the kiln flue gas, thereby providing reliable data support for the glass manufacturing process.

[0004] However, the traditional oxygen analyzer used for detecting flue gas in glass kilns is installed on the roof of the regenerator. Due to the high temperature and dust content in the flue gas, the instrument is easily burned or damaged, resulting in frequent equipment maintenance.

[0005] For example, the oxygen analyzer for a glass kiln is installed on the regenerative arch. It adjusts combustion in real time by detecting oxygen content to control nitrogen oxides at the source. However, the flue gas temperature here is above 1340℃ and the dust content in the flue gas is high. The sampling tube of the oxygen analyzer needs to be purged every week, and it is still frequently blocked and burned. Moreover, it needs to be inspected and repaired every six months, which greatly increases the operation and maintenance cost of the online equipment. Utility Model Content

[0006] This utility model discloses an installation structure for an oxygen analyzer used for detecting flue gas in glass kilns. It aims to solve the technical problem that the instrument is easily burned or damaged due to the high temperature and dust content in the flue gas when the sampling position is installed on the top of the regenerator, resulting in a high frequency of equipment maintenance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An oxygen analyzer installation structure for detecting flue gas in a glass kiln includes a regenerator chamber, a main flue, a first branch flue, a second branch flue, and two reversing dampers, and further includes:

[0009] Installation mechanism: The installation mechanism is set on the top outer wall of the first branch flue and the second branch flue. The top outer wall of the first branch flue and the second branch flue are provided with detection holes. One end of the detection hole is provided with a flange. The top outer wall of the first branch flue and the second branch flue are provided with connecting pipes. The inner wall of the connecting pipe is provided with an installation plate. The top outer wall of the installation plate is provided with an oxygen measuring probe. The bottom outer wall of the oxygen measuring probe is provided with a sampling tube.

[0010] Alarm mechanism: The alarm mechanism is disposed on the outer circumferential wall of the connecting pipe.

[0011] In this case, the sampling location was adjusted to the first and second flues outside the heat storage room, and set before the reversing gate and the main flue. The installation mechanism is located at the top of the two flues and is connected through the detection hole and flange. The oxygen probe is fixed by the mounting plate inside the connecting pipe. The sampling tube at the bottom of the oxygen probe accurately extracts the flue gas sample. This design cleverly moves the sampling point to the outside of the heat storage room, effectively avoiding the high temperature and high dust environment. The dust is deposited in the heat storage room, reducing the possibility of probe contamination or damage, effectively improving the reliability of the oxygen meter and reducing the frequency of equipment maintenance.

[0012] In a preferred embodiment, the alarm mechanism includes a smoke sensor disposed on the bottom outer wall of the mounting plate, and an alarm loop is connected to the smoke sensor.

[0013] The overall installation structure adopts a multi-layer structure, using an installation plate to divide the connecting pipes into two spaces. The smoke sensor is placed in the space near the detection port, forming dual monitoring and providing additional assurance for oxygen measurement results. During the operation of the glass furnace, if a leak occurs in the detection port or the sealing sleeve and sampling tube are not tightly fitted, the smoke sensor can respond quickly and trigger an alarm, thereby promptly reminding the operators to pay attention and take appropriate measures to prevent potential safety accidents and improve the accuracy and safety of flue gas detection.

[0014] As described above, an oxygen analyzer installation structure for detecting flue gas in glass kilns includes a heat storage chamber, a main flue, a first branch flue, a second branch flue, and two reversing dampers. It also includes: an installation mechanism: the installation mechanism is installed on the top outer wall of the first and second branch flues. Each of the top outer walls of the first and second branch flues has a detection hole, one end of which is fitted with a flange. Each of the top outer walls of the first and second branch flues has a connecting pipe, the inner wall of which is fitted with an installation plate. An oxygen probe is installed on the top outer wall of the installation plate, and a sampling tube is installed on the bottom outer wall of the oxygen probe. An alarm mechanism: the alarm mechanism is installed on the circumferential outer wall of the connecting pipe. The oxygen analyzer installation structure for detecting flue gas in glass kilns provided by this utility model has the technical effect of improving equipment reliability, reducing the frequency of equipment maintenance and cleaning, and alleviating the equipment maintenance pressure on on-site operators.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The oxygen analyzer installation structure disclosed in this utility model for detecting flue gas in glass kilns is mainly used in scenarios where the sampling position is installed on the roof of the regenerator, where the flue gas temperature is too high, the dust content in the flue gas is high, the instrument is easily burned or damaged, and the equipment maintenance frequency is high.

[0021] Reference Figure 1 and Figure 2 An oxygen analyzer installation structure for detecting flue gas in a glass kiln includes a heat storage chamber 1, a main flue 4, a first branch flue 2, a second branch flue 3, and two reversing dampers 17. It also includes: an installation mechanism: the installation mechanism is located on the top outer wall of the first branch flue 2 and the second branch flue 3. Detection holes 16 are provided on the top outer walls of both the first and second branch flues. A flange 15 is provided at one end of each detection hole 16. Connecting pipes 5 are provided on the top outer walls of both the first and second branch flues. An installation plate 10 is provided on the inner wall of the connecting pipe 5. An oxygen probe 8 is provided on the top outer wall of the installation plate 10. A sampling tube 9 is provided on the bottom outer wall of the oxygen probe 8. An alarm mechanism: the alarm mechanism is located on the circumferential outer wall of the connecting pipe 5.

[0022] Two reversing gates 17 are respectively installed on the inner walls of the first branch flue 2 and the second branch flue 3. The two ends of the first branch flue 2 and the second branch flue 3 are respectively connected to one side of the outer wall of the heat storage chamber 1 and one end of the main flue 4.

[0023] By relocating the real-time oxygen content monitoring point from the top of the heat storage chamber 1 to the first flue 2 and the second flue 3, the actual detection temperature dropped from above 1340℃ to below 550℃. After the flue gas passes through the heat storage chamber 1, the dust is greatly reduced through natural sedimentation. The cleaning frequency of the oxygen analyzer was reduced from once a week to once every six months, solving the problem of frequent equipment maintenance and cleaning. The change in the working environment indirectly extended the service life of the equipment.

[0024] In a specific implementation, the sampling position is adjusted to the first flue 2 and the second flue 3 outside the heat storage chamber 1, and is set before the reversing gate 17 and the main flue 4. The installation mechanism is located at the top of the two flues and is connected through the detection hole 16 and the flange 15. The oxygen probe 8 is fixed by the mounting plate 10 in the connecting pipe 5. The sampling tube 9 at the bottom of the oxygen probe 8 accurately extracts the flue gas sample. This design cleverly moves the sampling point to outside the heat storage chamber 1, effectively avoiding the high temperature and high dust environment. 70% of the dust is deposited in the heat storage chamber 1, reducing the possibility of probe contamination or damage, effectively improving the reliability of the oxygen meter and reducing the frequency of equipment maintenance.

[0025] Reference Figure 1 and Figure 3In a preferred embodiment, mounting holes are provided on the top outer walls of the mounting plate 10 and the flange 15, and a sealing sleeve 12 is provided on the inner circumferential wall of the mounting hole. The sampling tube 9 is installed on the inner circumferential wall of the sealing sleeve 12.

[0026] The tight fit between the sealing sleeve 12 and the sampling tube 9 greatly enhances the sealing performance of the installation structure, effectively preventing high-temperature and high-dust flue gas from leaking from the installation hole, thereby protecting the oxygen probe 8 from contamination and damage, and ensuring the accuracy and stability of the measurement data.

[0027] Reference Figure 1 and Figure 3 In a preferred embodiment, a sealing gasket 13 and a sealing cap 7 are provided on the top outer wall of the connecting pipe 5, and four equally spaced buckles are hinged on the circumferential outer wall of the connecting pipe 5.

[0028] The addition of sealing gasket 13 and sealing cap 7 significantly improves the sealing performance of connecting pipe 5, avoids the contamination of oxygen probe 8 by flue gas, and ensures the accuracy of measurement data (oxygen probe 8 transmits data wirelessly to oxygen analyzer). The detachable design of sealing cap 7 also facilitates equipment maintenance and replacement by operators, improving work efficiency.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, the alarm mechanism includes a smoke sensor 11, which is disposed on the bottom outer wall of the mounting plate 10, and an alarm ring 6 is connected to the smoke sensor 11.

[0030] In particular, the overall installation structure adopts a multi-layer structure, using the mounting plate 10 to divide the connecting pipe 5 into two spaces, and placing the smoke sensor 11 in the space near the detection hole 16 to form dual monitoring, providing additional protection for oxygen measurement results. During the operation of the glass furnace, if the detection hole 16 leaks or the sealing sleeve 12 and the sampling tube 9 are not tightly fitted, the smoke sensor 11 can respond quickly and trigger an alarm, thereby promptly reminding the operators to pay attention and take corresponding measures to prevent potential safety accidents and improve the accuracy and safety of flue gas detection.

[0031] Reference Figure 1 and Figure 3 In a preferred embodiment, the alarm ring 6 is disposed on the outer circumference of the connecting pipe 5, and a plurality of alarm lights are disposed on the outer circumference of the alarm ring 6.

[0032] Specifically, the alarm ring 6 connected to the smoke sensor 11 enables the alarm signal to be conveyed to the operator more clearly and intuitively. Once the smoke sensor 11 detects abnormal smoke, the alarm ring 6 will immediately emit a loud and continuous alarm sound, ensuring that the operator can clearly hear the alarm and react quickly even in a noisy kiln environment. The use of multiple alarm lights can form redundancy, so that even if one or more bulbs fail, the other bulbs can continue to work, ensuring the continuous issuance of the alarm signal.

[0033] Working principle: When in use, the sampling point is set before the reversing gate 17 and the main flue 4. The installation mechanism is set at the top of the two flues and connected through the detection hole 16 and flange 15. The oxygen probe 8 is fixed by the mounting plate 10 in the connecting pipe 5. Then, the flue gas sample is accurately extracted through the sampling tube 9 at the bottom of the oxygen probe 8 and the data is transmitted to the oxygen analyzer for analysis. When the detection hole 16 leaks or the sealing sleeve 12 and the sampling tube 9 are not tightly fitted, the smoke sensor 11 can quickly respond and trigger the alarm on the alarm ring, and the alarm light will emit a signal.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
