Description

Technical Field

[0001] This application relates to the technical field of glass processing, and more particularly to a glass furnace flue and a glass furnace. Background Technology

[0002] In current industrial production, the requirements for environmental protection are becoming increasingly stringent. The glass production process generates a large amount of flue gas mixed with dust. In order to avoid dust contamination of glass products, the flue gas needs to be discharged in a timely manner.

[0003] To facilitate the discharge of flue gas, glass kilns are usually connected to flues. The flue gas is discharged from the flue, and some dust settles and adheres to the inner wall of the flue. Therefore, it is necessary to clean the flue regularly to avoid blockage.

[0004] In existing technologies, dust settling locations are relatively dispersed, and the time required for dust removal is relatively long. During the cleaning process, heat is easily lost and the pressure is unstable inside the glass furnace, affecting the glass quality, such as CN220703508U. Utility Model Content

[0005] One of the technical problems this application aims to solve is the low cleaning efficiency caused by dust dispersion during the cleaning process of glass kiln flues.

[0006] To solve the above-mentioned technical problems, this application provides a glass furnace flue and a glass furnace.

[0007] According to this application, a glass furnace flue includes: a flue assembly; and a diversion assembly connected to and located within the flue assembly. The diversion assembly has a first diversion hole and a plurality of second diversion holes. The first diversion hole is located in the middle region of the diversion assembly, and the plurality of second diversion holes are located circumferentially outside the first diversion hole. Along the direction of flue gas flow, the projected area of ​​the first diversion hole is smaller than the projected area of ​​the second diversion holes.

[0008] In some embodiments, the first diversion holes include a plurality of first diversion holes located in the middle region of the diversion assembly, and the plurality of second diversion holes are uniformly distributed on the circumferential outer side of the plurality of first diversion holes.

[0009] In some embodiments, the first diversion hole is an elongated hole, and there are two first diversion holes, which are arranged sequentially along their own length direction.

[0010] In some embodiments, the first diversion hole is a circular hole, and the second diversion hole is an arc-shaped hole.

[0011] In some embodiments, the first diversion hole is a circular hole, and the flue assembly includes a first horizontal section, a first vertical section, and a second horizontal section. The first horizontal section, the first vertical section, and the second horizontal section are connected in sequence. The height of the first horizontal section in the vertical direction is higher than that of the second horizontal section, and the diversion assembly is disposed in the second horizontal section.

[0012] In some embodiments, the shunt components include a plurality of shunt components disposed at intervals within the second horizontal segment.

[0013] In some embodiments, the first vertical section has an air inlet, which is positioned toward the second horizontal section.

[0014] In some embodiments, the end of the second horizontal segment away from the first vertical segment has an air outlet, which is arranged opposite to the air inlet.

[0015] In some embodiments, the second horizontal segment further includes a dust removal port located between adjacent diversion components.

[0016] According to another aspect of this application, a glass furnace is also provided, which employs the aforementioned glass furnace flue, and the glass furnace includes an exhaust port, with the flue assembly connected to the exhaust port.

[0017] Through the above technical solution, the glass furnace flue and glass furnace provided in this application allow flue gas to enter the flue assembly and flow along the assembly. The first and second diversion holes on the diversion assembly divert the flue gas. Because the size of the first diversion hole is smaller than that of the second diversion hole, the flow velocity of the flue gas flowing out of the first diversion hole is greater than that flowing out of the second diversion hole. This creates a vortex behind the diversion assembly, promoting the settling of dust particles below the vortex formation area. The concentrated dust location facilitates cleaning. The technical solution of this application effectively solves the problem of low cleaning efficiency caused by dust dispersion in the prior art during the cleaning process of glass furnace flues.

[0032] like Figures 1 to 2 As shown, the glass furnace flue disclosed in Embodiment 1 of this application includes: a flue assembly 10 and a diversion assembly 20. The diversion assembly 20 is connected to the flue assembly 10 and located within the flue assembly 10. The diversion assembly 20 has a first diversion hole 21 and a plurality of second diversion holes 22. The first diversion hole 21 is located in the middle region of the diversion assembly 20, and the plurality of second diversion holes 22 are located on the circumferential outer side of the first diversion hole 21. Along the direction of flue gas flow, the projected area of ​​the first diversion hole 21 is smaller than the projected area of ​​the second diversion hole 22.

[0033] Applying the technical solution of Embodiment 1, the flue gas enters the flue assembly 10 and flows along it. The first diversion hole 21 and the second diversion hole 22 on the diversion assembly 20 divert the flue gas. Since the size of the first diversion hole 21 is smaller than that of the second diversion hole 22, the flow velocity of the flue gas flowing out of the first diversion hole 21 is greater than that flowing out of the second diversion hole 22. The flue gas forms a vortex behind the diversion assembly 20, promoting the settling of dust in the flue gas below the vortex formation area. The dust is concentrated, making it easier to clean. The technical solution of Embodiment 1 effectively solves the problem of low cleaning efficiency caused by dust dispersion in the cleaning process of glass kiln flues in the prior art.

[0034] like Figure 2As shown, in the technical solution of Embodiment 1, the first diversion hole 21 includes multiple first diversion holes 21, which are located in the middle region of the diversion component 20. Multiple second diversion holes 22 are evenly distributed on the circumferential outer side of the multiple first diversion holes 21. The arrangement of multiple first diversion holes 21 further diverts the flue gas in the middle region, accelerating the flue gas flow velocity. A reasonable design of the number and position of the first diversion holes 21 results in a good flue gas diversion effect, and the subsequent vortex formation is conducive to dust settling.

[0035] like Figure 2 As shown, in the technical solution of Embodiment 1, the first diversion hole 21 is an elongated hole, and there are two first diversion holes 21 arranged sequentially along their own length direction. In Embodiment 1, the length direction of the first diversion hole 21 is arranged vertically, and the gas flowing out of the first diversion hole 21 easily disperses in the width direction, that is, the horizontal direction. Vortexes are formed on both sides of the horizontal direction of the first diversion hole, and larger dust particles settle. Since the vortexes are located on both sides of the first diversion hole, the flow of gas in the vortexes does not easily affect the dust that has already been deposited below, causing the dust to be mixed into the flue gas again.

[0036] It should be noted that in other embodiments, the first diversion hole 21 and the second diversion hole 22 may also be of other shapes, as long as the cross-sectional area of ​​the first diversion hole 21 is smaller than the cross-sectional area of ​​the second diversion hole 22.

[0037] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the flue assembly 10 includes a first horizontal section 11, a first vertical section 12, and a second horizontal section 13. The first horizontal section 11, the first vertical section 12, and the second horizontal section 13 are connected sequentially. The first horizontal section 11 is higher than the second horizontal section 13 in the vertical direction. The diversion assembly 20 is disposed within the second horizontal section 13. The flue gas discharged from the glass furnace flows along the first horizontal section 11 into the first vertical section 12. The first vertical section 12 has a predetermined length, which is conducive to the cooling of the flue gas. Some of the gasified substances in the flue gas condense and adhere to the dust in the flue gas, increasing the particle size and mass of the dust, which is beneficial to subsequent dust settling. The cooled flue gas flows into the second horizontal section 13, where, under the action of the diversion assembly 20, a vortex is formed. Larger particles settle below the vortex formation zone under the influence of the vortex. The structure of the flue assembly 10 makes the dust accumulation more concentrated, which is beneficial to subsequent cleaning.

[0038] like Figure 1 and Figure 2As shown, in the technical solution of Embodiment 1, the diversion component 20 includes multiple components, which are arranged at intervals within the second horizontal section 13. While diverting the flue gas, the multiple diversion components 20 decelerate the flue gas, further promoting dust settling and reducing the dust content in the flue gas flowing out of the second horizontal section 13.

[0039] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the first vertical section 12 has an air inlet 121, which faces the second horizontal section 13. The air inlet 121 is connected to an air inlet pipe, and the end of the air inlet pipe away from the air inlet 121 is connected to an air source. The air source provides compressed air, which enters the flue assembly 10 from the air inlet 121, increasing the flue gas velocity within the flue assembly 10, reducing dust settling at the junction of the first vertical section 12 and the second horizontal section 13, and preventing flue blockage that would hinder flue gas emission and affect the internal pressure of the glass furnace. Simultaneously, the addition of compressed air further promotes flue gas cooling and increases dust settling.

[0040] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the end of the second horizontal section 13 away from the first vertical section 12 has an air outlet 131, which is arranged opposite to the air inlet 121. The air outlet 131 is connected to an induced draft fan. The induced draft fan accelerates the outflow of flue gas in the flue assembly 10 and avoids the flue gas not being discharged from the second horizontal section 13 in time due to the slow vortex flow velocity.

[0041] like Figure 3 As shown, the difference between the technical solution of Embodiment 2 and Embodiment 1 is that the first diversion hole 21 is a circular hole, and the second diversion hole 22 is an arc-shaped hole. The airflow from the circular first diversion hole 21 is more uniform, and the subsequent vortex is less likely to form turbulence. In Embodiment 2, there are two second diversion holes 22, which are symmetrically arranged on both sides of the first diversion hole 21 in the vertical direction. The center of the second diversion hole 22 and the arc-shaped side are the same as the center of the first diversion hole 21. The first diversion hole 21 and the second diversion hole 22 in this distribution form a uniformly distributed vortex and avoid the bottom of the dust deposition area, reducing the possibility of the vortex driving the already deposited dust to move.

[0042] like Figure 4As shown, the difference between the technical solution of Embodiment 3 and Embodiment 1 is that the second horizontal section 13 further includes a dust removal port 132, which is located between adjacent diversion components 20. Dust accumulates behind the diversion component 20, and a dust removal port 132 is provided at the corresponding position. A discharge gate is provided at the dust removal port 132, and the discharge gate is connected to the dust removal port 132 by a hinge. The dust removal port 132 is located at the bottom of the second horizontal section 13. When the discharge gate is opened, the dust falls directly under the action of gravity, resulting in high cleaning efficiency. In other embodiments, the dust removal port 132 can also be located on the side of the second horizontal section 13. When the discharge gate is opened, the interior of the second horizontal section can be manually cleaned by workers to reduce cleaning dead corners. The second horizontal section 13 also includes a gate, which is located on the side of the diversion component 20 near the first vertical section 12. The second horizontal section 13 has an opening for the gate to pass through, and the gate is movably installed in the opening to control the opening and closing of the gate. When it is necessary to clean the dust deposited behind the diversion component 20, close the gate to stop the flue gas from being discharged into the glass furnace flue. This prevents the pressure inside the glass furnace from suddenly dropping during the cleaning process, which could affect the stability of the process inside the glass furnace. It also prevents the overflow of high-temperature flue gas during the cleaning process from polluting the environment and causing burns to workers during manual cleaning.

[0043] According to another aspect of this application, a glass furnace is also provided. The glass furnace employs the aforementioned glass furnace flue, and includes an exhaust port. A flue assembly 10 is connected to the exhaust port. The flue gas discharged from the glass furnace enters the aforementioned glass furnace flue, and a diversion assembly 20 diverts the flue gas, promoting the settling of dust particles in the flue gas. This results in a more concentrated dust distribution, preventing flue blockage, reducing furnace pressure fluctuations, and improving the quality of the glass products.

[0044] In summary, the main components of this application include a furnace flue (flue assembly 10), a settling chamber (the area between adjacent diversion assemblies 20), flue refractory material, a settling chamber partition wall (diversion assembly 20), a horizontal flue (second horizontal section 13), and a vertical flue (first vertical section 12). The glass furnace for photovoltaic glass uses a make-up air inlet (air inlet 121) for the flue. The flue (glass furnace flue) is directly connected to the furnace body and can be installed at the front or side of the furnace. The flue material is constructed using refractory materials, such as fused zirconia corundum, mullite, and sillimanite. The closer to the glass furnace, the better the temperature resistance of the refractory material. During the melting of the glass, a dust collector creates negative pressure through a make-up air fan, drawing air through the outlet 131. The flue gas flows from the furnace to the induced draft duct, and its temperature gradually decreases during this flow. As the temperature changes from high to low, the flue gas dust gradually cools and settles. An air inlet is added to the bottom of the settling chamber. The partition wall uses wider, narrower ventilation holes (second diversion holes 22) on both sides to separate the two sides, and a narrower, narrower ventilation hole (first diversion hole 21) in the middle of the partition wall. When the airflow passes through the settling chamber, the speed is fastest in the middle and slower on the sides. By adjusting the size and position of the ventilation holes in the partition wall, in conjunction with the air inlet at the bottom of the settling chamber, the flue gas will form a vortex in the settling chamber, causing the heavier components in the flue gas to settle at the bottom. Due to the addition of the air inlet (air inlet 121), the airflow speed will be accelerated at this point, so the dust in the flue gas enters the horizontal flue and does not settle at the connection between the settling chamber and the horizontal flue. Blockage in the flue affects the exhaust pressure, which in turn affects the pressure inside the kiln. To clean accumulated ash, doors can be opened on the sides of the settling chamber and the horizontal flue for easy dust removal.
