Description

Technical Field

[0001] This application relates to the field of glass transportation technology, and in particular to a flue gas treatment device and method for borosilicate glass kilns. Background Technology

[0002] In the production of borosilicate glass, boron and nitrogen oxides are easily volatilized during the production of borosilicate pharmaceutical glass, and raw material dust from the glass furnace can enter the flue along with the flue gas. The volatile borate compounds accumulate in the glass furnace flue, turning into molten glass that adheres to the flue and can clog it, affecting processing efficiency.

[0003] The traditional method involves opening a duct and using cleaning tools to clean the volatiles adhering to the inner wall of the duct. The duct is connected to the desulfurization and denitrification equipment, and some of the boron-containing flue gas enters the desulfurization and denitrification equipment.

[0004] This method cannot effectively maintain the temperature inside the system. During cleaning, it is easy to cause heat loss inside the kiln. Furthermore, it can cause equipment blockage and operational difficulties when entering the desulfurization and denitrification equipment, such as CN219317277U. Summary of the Invention

[0005] One of the technical problems this application aims to solve is the problem of boride volatiles condensing into solids and clogging flues and desulfurization and denitrification equipment during the glass production process.

[0006] To address the aforementioned technical problems, this application provides a borosilicate glass furnace flue gas treatment device and a flue gas treatment method.

[0007] According to this application, a borosilicate glass kiln flue gas treatment device includes: a buffer assembly, which includes a buffer chamber structure, a first air inlet structure, and a first air outlet pipe. The first air inlet structure is connected to the buffer chamber structure, and the first end of the first air outlet pipe is connected to the buffer chamber structure.

[0008] In some embodiments, the processing chamber structure includes a processing chamber and a plurality of partitions, the plurality of partitions being connected to the inner wall of the processing chamber, the plurality of partitions being arranged at intervals, the plurality of partitions having openings, and the openings of adjacent partitions being staggered.

[0009] In some embodiments, the cleaning structure includes a rotating shaft and a plurality of blades, the plurality of blades being connected to the rotating shaft, the rotating shaft being rotatably connected to the processing chamber, and the plurality of blades being correspondingly arranged with a plurality of partitions.

[0010] In some embodiments, the second air intake structure is disposed corresponding to the second end of the first air outlet pipe, and the inner diameter of the second air intake structure is larger than the inner diameter of the first air outlet pipe structure. In some embodiments, the cooling structure includes a cooling chamber, a liquid inlet, and a liquid outlet. The processing chamber structure is disposed inside the cooling chamber, with the liquid inlet connected to the cooling chamber and the liquid outlet connected to the cooling chamber.

[0011] In some embodiments, the buffer chamber structure includes a buffer chamber and a plurality of baffles. The buffer chamber has a flue gas inlet. The first side of the plurality of baffles is connected to the inner wall of the buffer chamber and is arranged perpendicular to the exhaust direction of the flue gas inlet. The second side of the plurality of baffles has a gap with the inner wall of the buffer chamber. The first air intake structure is arranged parallel to the baffles.

[0012] According to another aspect of this application, a flue gas treatment method is also provided. The flue gas treatment method uses the above-mentioned borosilicate glass furnace flue gas treatment equipment and includes the following steps: Monitor the outlet air temperature of the first outlet air pipe and ensure 480℃ < <520℃; Monitor the outlet air temperature of the second outlet pipe and ensure 340℃ < <360℃.

[0013] In some embodiments, the flue gas treatment method satisfies the following conditions: when 340℃ or At 360℃, Adjust the air intake volume of the first air intake structure; Adjust the air intake volume of the second air intake structure; Adjust the temperature of the cooling structure; Adjust the rotation speed of the cleaning structure.

[0014] In some embodiments, the flue gas treatment method satisfies the following conditions: when At 480℃, Adjust the air intake volume of the second air intake structure; Adjust the temperature of the cooling structure; Adjust the rotation speed of the cleaning structure.

[0015] In some embodiments, the flue gas treatment method satisfies the following conditions: when At 520℃, adjust the intake volume of the first intake structure.

[0016] Through the above technical solution, the borosilicate glass kiln flue gas treatment equipment provided in this application connects the buffer assembly to the flue, and the second outlet pipe to the desulfurization and denitrification equipment. The flue gas to be treated enters the buffer assembly, and the first inlet structure introduces cooling gas into the buffer chamber structure to cool the flue gas. The buffer chamber structure reduces the flue gas velocity, and large particles in the flue gas fall to the bottom of the buffer chamber structure under gravity. The flue gas then flows out from the first outlet pipe and enters the treatment assembly.

[0027] like Figures 1 to 3 As shown in the embodiment of this application, the borosilicate glass furnace flue gas treatment equipment includes: a buffer assembly 10 and a treatment assembly 20. The buffer assembly 10 includes a buffer chamber structure 11, a first air inlet structure 12 and a first air outlet pipe 13. The first air inlet structure 12 is connected to the buffer chamber structure 11, and the first end of the first air outlet pipe 13 is connected to the buffer chamber structure 11. The treatment assembly 20 includes a cooling structure 21, a treatment chamber structure 22, a second air inlet structure 23, a second air outlet pipe 24 and a cleaning structure 25. The treatment chamber structure 22 is connected to the second end of the first air outlet pipe 13, the cooling structure 21 is connected to the treatment chamber structure 22, the second air inlet structure 23 is connected to the treatment chamber structure 22, the second air outlet pipe 24 is connected to the treatment chamber structure 22, and the cleaning structure 25 is rotatably connected to the treatment chamber structure 22 and disposed within the treatment chamber structure 22.

[0028] Applying the technical solution of this application embodiment, the buffer assembly 10 is connected to the flue, and the second outlet pipe 24 is connected to the desulfurization and denitrification equipment. The flue gas to be treated enters the buffer assembly 10. The first inlet structure 12 introduces cooling gas into the buffer chamber structure 11 to cool the flue gas. The buffer chamber structure 11 reduces the flue gas flow rate, and large particles in the flue gas fall to the bottom of the buffer chamber structure 11 under gravity. The flue gas flows out from the first outlet pipe 13 and enters the treatment assembly 20. The second inlet structure 23 introduces cooling gas into the treatment chamber structure 22 to further cool the flue gas, causing the borides in the flue gas to condense. The cleaning structure 25 rotates to clean the treatment chamber structure 22, preventing the accumulation of borides. The technical solution of this embodiment effectively solves the problem in the prior art where boride volatiles condense into solids and block the flue gas and desulfurization and denitrification equipment during the glass production process.

[0029] like Figures 1 to 3As shown, in this embodiment, the processing chamber structure 22 includes a processing chamber 221 and multiple partitions 222. The partitions 222 are connected to the inner wall of the processing chamber 221 and are spaced apart. Each partition has an opening 2221, and the openings 2221 of adjacent partitions are staggered. The partitions 222 obstruct the flow of flue gas, reducing its velocity and preventing smaller particles from flowing upwards. The staggered positions of the openings 2221 between adjacent partitions improve the deceleration effect on the flue gas. The placement of the openings 2221 also prevents interference between the partitions 222 and the cleaning structure 25 while allowing flue gas to flow through.

[0030] like Figures 1 to 3 As shown, in this embodiment, the cleaning structure 25 includes a rotating shaft 251 and multiple blades 252. The blades 252 are connected to the rotating shaft 251, which is rotatably connected to the processing chamber 221. The blades 252 are correspondingly arranged with multiple partitions 222. The rotating shaft 251 is connected to the output shaft of a motor. When the motor starts, it drives the rotating shaft 251 and the blades 252 to rotate. The rotation of the blades 252 scrapes off the dust accumulated on the partitions 222 until the dust falls to the bottom of the processing chamber structure 22. A dust removal port is provided at the bottom of the processing chamber structure 22, which needs to be opened periodically to clean the dust at the bottom of the processing chamber structure 22. The partitions 222 are fan-shaped structures with openings 2221, designed according to the rotation radius of the blades 252. The central angle of the openings 2221 is 30° to 90°. The movement path of the blades 252 can cover the entire partition 222, resulting in more thorough cleaning. As the blade 252 rotates, it exerts a downward force on the airflow, further slowing down the flue gas flow speed and preventing small dust particles from flowing into the desulfurization and denitrification equipment.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the second air intake structure 23 is correspondingly arranged with the second end of the first air outlet pipe 13, and the inner diameter of the second air intake structure 23 is larger than the inner diameter of the first air outlet pipe 13. The speed of the cold air entering the second air intake structure 23 is less than the speed of the flue gas flowing out of the first air outlet pipe 13, which prevents the flue gas in the first air outlet pipe 13 from failing to flow into the processing chamber structure 22. Furthermore, under the impact of the flue gas flowing out of the first air outlet pipe 13, the cold air entering the second air intake structure 23 is enveloped by the flue gas, resulting in higher cooling efficiency.

[0032] like Figure 1 and Figure 2As shown in the technical solution of this embodiment, the cooling structure 21 includes a cooling chamber 211, a liquid inlet 212, and a liquid outlet 213. The processing chamber structure 22 is disposed inside the cooling chamber 211. The liquid inlet 212 is connected to the cooling chamber 211, and the liquid outlet 213 is also connected to the cooling chamber 211. Cooling liquid is introduced into the liquid inlet 212, and the cooling liquid enters the cooling chamber 211 to cool the entire processing chamber structure 22, thereby further cooling the flue gas inside the processing chamber structure 22. This causes the borides in the flue gas to condense and remain inside the processing chamber structure 22, preventing the borides from entering the desulfurization and denitrification equipment and clogging it.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the buffer chamber structure 11 includes a buffer chamber 111 and multiple baffles 112. The buffer chamber 111 has a flue gas inlet 1111. The first side of the multiple baffles 112 is connected to the inner wall of the buffer chamber 111 and is perpendicular to the outlet direction of the flue gas inlet 1111. The second side of the multiple baffles 112 has a gap with the inner wall of the buffer chamber 111. The first air intake structure 12 is arranged parallel to the baffles 112. The first baffle 112 is connected to the upper part of the buffer chamber 111, and the second baffle 112 is connected to the lower part of the buffer chamber 111. The internal airflow flows along an S-shaped path. The multiple baffles 112 obstruct the flow of flue gas, reduce the flue gas velocity, and large dust particles fall to the bottom of the buffer chamber structure 11. A pull-out collection groove is provided at the bottom of the buffer chamber 111 to facilitate the cleaning of dust inside the buffer chamber 111 by the staff. The first air intake structure 12 includes a first inlet 121 and a second inlet 122. The first inlet 121 is located between the first baffle 112 and the flue gas inlet 1111, and is perpendicular to the flue gas inlet 1111. Cooling gas is introduced into the first inlet 121 to cool the flue gas, reduce the flue gas velocity, and change the flue gas flow direction. The second inlet 122 is correspondingly located to the second baffle 112. Cooling gas is introduced into the second inlet 122 to reduce the flue gas velocity on the side of the second baffle 112 closer to the flue gas inlet 1111 and change the flue gas flow direction on the side farther from the flue gas inlet 1111, further accelerating dust settling.

[0034] According to another aspect of this application, a flue gas treatment method is also provided. The flue gas treatment method uses the above-mentioned borosilicate glass furnace flue gas treatment equipment and includes the following steps: Monitor the outlet air temperature of the first outlet air pipe 13 and ensure 480℃ < <520℃; Monitor the outlet air temperature of the second outlet pipe 24 and ensure 340℃ < <360℃.

[0035] Temperature detectors are installed at the first outlet pipe 13 and the second outlet pipe 24, respectively. The melting point of the boride is approximately 450°C, and the temperature inside the buffer assembly 10 is higher than the outlet temperature of the first outlet pipe 13. At this point, the boride exists in both liquid and gaseous states, flowing into the treatment unit 20 along with the flue gas. The optimal temperature for the denitrification process is 320℃~380℃, ensuring that it is below 340℃. At a temperature of <360℃, not only can borates be deposited within the treatment chamber structure 22, but the flue gas temperature introduced into the desulfurization and denitrification equipment is also ensured to be at a suitable temperature.

[0036] Flue gas treatment methods must meet the following conditions: when 340℃ or At 360℃, Adjust the intake volume of the first intake structure 12; Adjust the intake volume of the second intake structure 23; Adjust the temperature of cooling structure 21; Adjust the rotation speed of the cleaning structure 25.

[0037] Table 1 shows the process parameters of the borosilicate glass furnace flue gas treatment equipment under normal operation.

[0038] Table 1

[0039] Table 2 shows the effects of other factors on flue gas temperature at flue gas inlet 1111 when the flue gas temperature is basically stable. The magnitude of the impact.

[0040] Table 2

[0041] Within the adjustable range of each parameter, adjusting the flow rate of the second intake structure 23 and the first inlet 121 and the second inlet 122 affects... and The impact is most pronounced. Since the air intake volume of the first inlet 121 significantly affects the airflow direction within the glass furnace flue, it is advisable to prioritize adjusting the air intake volume of the second inlet structure 23, and this volume should not exceed the flue gas velocity at the flue gas inlet 1111 to prevent positive pressure from forming within the system, which could lead to backflow. Adjusting the rotational speed of the shaft 251 and the circulating water intake volume also has an impact on... The impact is not obvious, on There is an impact, but it is relatively small. The increased flow of circulating water will undoubtedly lead to excessively high pressure within the treatment chamber structure 22, significantly affecting it. However, the circulating water should maintain a certain flow rate to protect the internal structure of the treatment chamber 22.

[0042] Therefore when At 360℃, priority should be given to adjusting the rotational speed of the cleaning structure 25, the temperature of the cooling structure 21, the air intake volume of the first air intake structure 12, and the air intake volume of the second air intake structure 23. After adjusting to the specified range, the rotational speed of the shaft 251 should be gradually reduced to decrease the cooling water intake. Then, the air intake volumes of the second air intake structure 23 and the first air intake structure 12 should be adjusted repeatedly to gradually maintain system balance. The purpose of this is to use the shaft 251 and the cooling water intake volume for fine-tuning of the device's state to ensure device stability.

[0043] when At 340℃, priority should be given to adjusting the air intake volume of the second air intake structure 23, the air intake volume of the first air intake structure 12, the temperature of the cooling structure 21, and the rotation speed of the cleaning structure 25. This setup aims to minimize the amount of fresh air introduced, thereby reducing the pressure on the downstream processing stage.

[0044] Flue gas treatment methods must meet the following conditions: when At 480℃, Adjust the intake volume of the second intake structure 23; Adjust the temperature of cooling structure 21; Adjust the rotation speed of the cleaning structure 25.

[0045] The following steps should be performed simultaneously and sequentially: reduce the air intake of the second air intake structure 23; reduce the liquid inlet 212; adjust the rotation speed of the shaft 251; until the temperature A recovers to 490℃~510℃, the air intake of the second air intake structure 23, the cooling water intake, and the rotation speed of the shaft 251 should be restored to the parameters before adjustment. If the final temperature is not within the range of 480℃~520℃, further adjustments should be made.

[0046] Flue gas treatment methods must meet the following conditions: when At 520℃, adjust the intake volume of the first intake structure 12.

[0047] The air intake volume of the first air intake structure 12 and the second air intake structure 23 should be increased. This is because the air intake volume of the first air intake structure 12 has a significant impact on the airflow direction in the flue. The air intake volume of the second air intake structure 23 should be adjusted first to prevent disturbance to the gas state in the kiln.

[0048] In summary, this invention provides an apparatus and method for pre-treatment of flue gas from a borosilicate glass kiln (borosilicate glass kiln flue gas treatment equipment and flue gas treatment method). This apparatus is installed at the front end of the glass kiln flue, and can be installed after the waste heat boiler, or used before the denitrification equipment without a waste heat boiler. The treatment apparatus includes two parts: a buffer chamber (buffer assembly 10) and a treatment chamber (treatment assembly 20). The buffer chamber serves two purposes: firstly, to stabilize and reduce the flue gas velocity, preventing significant fluctuations in the kiln's internal environment during flue gas treatment; secondly, to significantly reduce the flue gas temperature and settle a large amount of coarse dust particles in this area, preventing blockage of the downstream flue and treatment chamber, thus affecting treatment efficiency. The treatment chamber serves two purposes: firstly, to further reduce the flue gas temperature and further settle dust particles; and secondly, to finely adjust the temperature of the flue gas entering the denitrification equipment to obtain the most suitable desulfurization and denitrification flue gas temperature, achieving optimal treatment efficiency. Since the melting point of boron oxide is approximately 450℃, the optimal temperature for the SCR denitrification process is 320℃~380℃, with an intermediate value of 350℃. Therefore, to ensure the stable operation of the denitrification equipment, boron oxide should precipitate and be neutralized before denitrification. Thus, the method proposed in this application sets the flue gas temperature at the induced draft pipe (second outlet pipe 24) to 350℃, with a treatment range of 340℃~360℃ and a control temperature range of 330℃~370℃. To prevent boron oxide precipitation in the buffer chamber, the flue gas temperature at the connecting pipe (first outlet pipe 13) is controlled at 500℃ to ensure that boron oxide is in a gaseous state at this temperature. The control temperature range is 480℃~520℃. The buffer chamber is located at the front end of the treatment chamber and connected via a connecting pipe. The flue at the other end of the buffer chamber is connected to the outlet of the waste heat boiler, or directly connected to the kiln flue when no waste heat boiler is installed. The buffer chamber is divided into multiple interconnected areas by baffles 112. The upper part of the first baffle 112, located near the flue, is connected to the upper inner wall of the buffer chamber 111, while the lower part forms a gap with the lower inner wall of the buffer chamber 111 to facilitate the passage of flue gas. The other baffle is configured in the opposite way, with its upper part connected to the lower inner wall of the buffer chamber 111 and its upper part forming a gap with the upper inner wall of the buffer chamber 111. The first air inlet (first inlet 121) is perpendicular to the flue and on the same plane. Fresh air is introduced from the first air inlet and impacts the flue gas entering the flue, creating a downward force that causes the flue gas to change its direction of movement, facilitating dust settling. The second air inlet (second inlet 122) is located on top of the second baffle. It slows down the flue gas in the second cavity and creates a downward force for the flue gas entering the third cavity, further changing the direction of movement of the flue gas. Finally, the flue gas passes through the third baffle and flows into the treatment chamber through the connecting pipe. Two ash collection trays are installed below the buffer chamber, and the trays are separated from the bottom by a second baffle. To prevent flue gas leakage when the ash collection trays are removed for cleaning, a baffle is installed outside the trays for sealing.One end of the treatment chamber is connected to the buffer chamber via a connecting pipe. A cold air inlet (second air intake structure 23) is positioned opposite the connecting pipe on the other side, with a cross-sectional area larger than the connecting pipe. The velocity of the incoming cold air is lower than that of the flue gas from the connecting pipe, allowing the flue gas to move smoothly to the first partition (partition 222) below the treatment chamber. Meanwhile, an exhaust duct (second exhaust pipe 24) is installed at the top of the treatment chamber to create negative pressure within it. The other end of the exhaust duct is connected to the denitrification equipment. Multiple fan-shaped partitions 222 are installed inside the treatment chamber, arranged in an alternating pattern. A dust removal port is located at the bottom of the treatment chamber, equipped with a valve or dust collection bag for easy dust removal. The treatment chamber has a jacketed structure, with inner and outer layers forming a jacket. A water inlet (liquid inlet 212) is located at the bottom of the jacket, and a drain outlet (liquid outlet 213) is located at the top. Cooling medium, typically circulating cooling water, is introduced into the jacket to cool the flue gas within it. A rotating shaft 251 is installed at the center of the treatment chamber, driven by a motor. Multiple sets of blades 252 are mounted on the shaft 251. The two lowest sets of blades 252 prevent dust from agglomerating at the bottom, facilitating cleaning. Each set of upper blades 252 is positioned above a baffle 222, corresponding to a single baffle. The blades 252 generate a downward force, creating turbulence in the flue gas within the treatment chamber 221. Furthermore, the rotating blades clean up any sediment that falls into the treatment chamber 221, allowing for internal cleaning during equipment operation; only periodic venting through the dust removal port is required. Quicklime water can be added to the uppermost baffle to adsorb and clean precipitated boron oxide and absorb and neutralize sulfides. Temperature control is implemented by installing temperature probes at the exhaust duct and connecting pipes. The connecting pipe monitors temperature A, and the exhaust duct monitors temperature B. Temperature control of B has higher priority than temperature control of A. Temperature B should be controlled between 340℃ and 360℃. When the temperature is between 330℃ and 370℃, adjustments should be made. If temperature B is too low, the following should be selected first: a. Reduce the air intake volume at the cold air vent; b. Reduce the air intake volume at the first and second air intakes; c. Reduce the cooling water flow rate; d Adjust the rotation speed of shaft 251; The purpose of this setup is to prioritize minimizing the amount of fresh air introduced, thereby reducing the pressure on the backend processing.

[0049] Similarly, when temperature B is too high, the following should be selected first: a. Adjust the rotational speed of shaft 251; b. Increase the cooling water flow rate; c. Increase the air intake volume of the cold air vent; d. Increase the air intake volume of the first air intake and the second air intake; Temperature A controls the temperature range to 480℃~520℃. When A is too high, adjustment will be prioritized. a. Increase the air intake volume at the second air intake; b. Increase the size of the first air intake.

[0050] This is because the air intake of the first air inlet has a significant impact on the airflow direction in the flue. Therefore, the air intake of the second air inlet is adjusted first to prevent disturbance to the gas state inside the kiln.

[0051] If the temperature is already below 480℃, the following steps should be performed simultaneously: a. Reduce the air intake volume at the cold air vent; b. Reduce the cooling water flow rate; c. Adjust the rotation speed of shaft 251; Until temperature A recovers to 490℃~510℃.

[0052] The air intake volume of the cold air vent, the cooling water intake volume, and the rotation speed of the shaft should be restored to the parameters before adjustment. If the final temperature is not within the range of 480℃~520℃, further adjustments should be made.
