[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0034] like Figures 1 to 5 As shown, the glass kiln flue gas treatment device disclosed in Example 1 of the present application includes: an air intake pipe 10, a first dust removal pipe assembly 20, a second dust removal pipe assembly 30 and a spare assembly. The first end of the air intake pipe 10 is connected to the air outlet of the glass kiln flue, and the second end of the air intake pipe 10 has a first branch 11, a second branch 12 and a third branch 13. The first dust removal pipe assembly 20 is connected to the first branch 11, and the first dust removal pipe assembly 20 is connected to the exhaust equipment. A first valve is provided on the first dust removal pipe assembly 20, and the second dust removal pipe assembly 30 is connected to the second branch 12. The second dust removal pipe assembly 30 is connected to the exhaust equipment. A second valve is provided on the second dust removal pipe assembly 30, and a spare pipe 40 is connected to the third branch 13. The spare pipe 40 is connected to the exhaust equipment, and a third valve is provided on the spare pipe 40.
[0035] Applying the technical solution of Example 1, the kiln exhaust gas enters the air intake pipe 10, the first valve is opened, the second valve and the third valve are closed, and the flue gas passes through the first dust removal pipe assembly 20 for dust removal. If the first dust removal pipe assembly 20 is blocked by borides or fails, the first valve and the third valve are closed, the second valve is opened, and the flue gas passes through the second dust removal pipe assembly 30 for dust removal. The first dust removal pipe assembly 20 and the second dust removal pipe assembly 30 are used alternately, which is convenient for the staff to clean them in time to avoid blockage, and the entire device can still complete dust removal while the cleaning process is in progress. If both the first dust removal pipe assembly 20 and the second dust removal pipe assembly 30 cannot be used, the first valve and the second valve are closed, the third valve is opened, and the flue gas is passed into the exhaust equipment from the spare pipe 40. The technical solution of Example 1 effectively solves the problem of low exhaust gas treatment efficiency caused by boron compounds blocking the gas path during the dust removal process of the flue gas of the medium borosilicate glass kiln in the prior art.
[0036] like Figures 1 to 4 As shown, in the technical solution of Example 1, the first dust removal pipeline assembly 20 includes a first dust removal pipeline 21, a first cyclone dust removal structure 22, a first cooling structure 23, and a first bag dust removal structure 24. The first end of the first dust removal pipeline 21 is connected to the first branch 11, and the first cyclone dust removal structure 22, the first cooling structure 23, and the first bag dust removal structure 24 are arranged in sequence from the first end of the first dust removal pipeline 21 to the second end of the first dust removal pipeline 21. When the flue gas enters the air intake pipeline 10, the first valve is opened, and the second and third valves are closed, the flue gas flows from the first branch 11 into the first dust removal pipeline 21 and passes through the first cyclone dust removal structure 22, the first cooling structure 23, and the first bag dust removal structure 24 in sequence. The first cyclone dust removal structure 22 uses centrifugal force to remove larger and heavier particles from the flue gas. The first cooling structure 23 cools the flue gas to 110°C, causing some boride in the flue gas to crystallize. The flue gas then passes into the first bag dust removal structure 24 for dust removal. The boride particles are trapped by the bags and adhere to the bag surfaces. Clean gas is then discharged from the first bag dust removal structure 24. The first cyclone dust removal structure 22, the first cooling structure 23, and the first bag dust removal structure 24 work together to remove boride particles from the flue gas, ensuring that the exhaust gas meets emission standards and reduces environmental pollution.
[0037] like Figure 1 and Figure 5As shown, in the technical solution of Example 1, the second dust removal pipeline assembly 30 includes a second dust removal pipeline 31, a second cyclone dust removal structure 32, a second cooling structure 33, and a second bag dust removal structure 34. The first end of the second dust removal pipeline 31 is connected to the second branch 12, and the second cyclone dust removal structure 32, the second cooling structure 33, and the second bag dust removal structure 34 are arranged in sequence from the first end of the second dust removal pipeline 31 to the second end of the second dust removal pipeline 31. When the first dust removal pipeline assembly 20 is blocked, the first valve is closed and the second valve is opened, and the flue gas is passed into the second dust removal pipeline assembly 30 and passes through the second cyclone dust removal structure 32, the second cooling structure 33, and the second bag dust removal structure 34 in sequence. The second cyclone dust removal structure 32 uses centrifugal force to remove larger and heavier particles from the flue gas. The second cooling structure 33 cools the flue gas to 110°C. Some of the boride in the flue gas crystallizes and then passes into the second bag dust removal structure 34 for dust removal. The boride particles are blocked by the bag and adhere to the surface of the bag. Clean gas is discharged from the second bag dust removal structure 34. The second cyclone dust removal structure 32, the second cooling structure 33 and the second bag dust removal structure 34 work together to remove the boride particles in the flue gas, so that the exhaust gas meets the emission standards and reduces environmental pollution. When the first dust removal pipeline assembly 20 is activated, the second dust removal pipeline assembly 30 is cleaned to prevent it from being blocked. The second dust removal pipeline assembly 30 is used alternately with the first dust removal pipeline assembly 20 to achieve continuous dust removal of the flue gas and improve dust removal efficiency.
[0038] like Figure 2As shown, in the technical solution of Example 1, the first cyclone dust removal structure 22 includes a first air inlet 221, a first air outlet 222, a first dust removal bin 223 and a first feed pipeline 224, the first air inlet 221 is connected to the first dust removal bin 223, the first air outlet 222 is connected to the first dust removal bin 223, the first end of the first feed pipeline 224 is connected to the first dust removal bin 223, and the second end of the first feed pipeline 224 is connected to the quicklime discharge device. The first dust removal bin 223 includes a conical section and a cylindrical section, the cylindrical section is connected to the conical section, and the first air outlet 222 is arranged on the cylindrical section. The first air outlet has a predetermined angle with the horizontal direction. The exhaust gas enters from the first air outlet 222 and flows downward along the inner wall of the first dust removal bin 223 to form a conical spiral gas. Under the action of centrifugal force, the particles in the gas collide with the inner wall of the first dust removal bin 223, and the particle speed is reduced and falls to the bottom of the first dust removal bin 223 along the inner wall of the first dust removal bin 223 under the action of gravity. A conical guide structure is provided at the bottom of the first dust removal bin 223, and there is a gap between the conical guide structure and the inner wall of the first dust removal bin 223. The solid particles fall from the gap into the recovery box arranged below the first dust removal bin 223. After the gas hits the upper surface of the conical guide structure, it moves upward and is discharged from the first air outlet 222 above. Quicklime slurry is introduced from the first feed line 224 into the first dust removal bin 223. Sulfides and other substances in the exhaust gas react with the quicklime slurry to achieve exhaust gas desulfurization. The reacted quicklime, under the action of centrifugal force, falls into the recovery bin along with the solid particles. The first feed line 224 includes multiple discharge ports, which are evenly arranged and have a diameter of less than 2 mm. This structure ensures that the quicklime ejected from the first feed line 224 is evenly distributed, making the desulfurization reaction more thorough. Furthermore, smaller quicklime slurry droplets are more susceptible to the influence of centrifugal force, which is conducive to the smooth operation of the first cyclone dust removal structure 22.
[0039] like Figure 5 As shown, in the technical solution of Example 1, the second cyclone dust removal structure 32 includes a second air inlet 321, a second air outlet 322, a second dust removal bin 323, and a second feed line 324. The second air inlet 321 is connected to the second dust removal bin 323, the second air outlet 322 is connected to the second dust removal bin 323, the first end of the second feed line 324 is connected to the second dust removal bin 323, and the second end of the second feed line 324 is connected to the quicklime discharge device. The second cyclone dust removal structure 32 shares the same structural principles as the first cyclone dust removal structure 22. The second cyclone dust removal structure 32 can also remove and desulfurize large particulate impurities in the exhaust gas, further reducing residual pollutants in the exhaust gas.
[0040] like Figure 1As shown, in the technical solution of Example 1, the first end of the standby pipeline 40 is connected to the third branch 13, and the second end of the standby pipeline 40 includes a fourth branch 41 and a fifth branch 42. The fourth branch 41 is connected to the first dust removal pipeline 21, and a fourth valve is provided on the fourth branch 41. The fifth branch 42 is connected to the second dust removal pipeline 31, and a fifth valve is provided on the fifth branch 42. The fourth branch 41 is provided on the side of the first bag dust removal structure 24 away from the first cooling structure 23, and the fifth branch 42 is provided on the side of the second bag dust removal structure 34 away from the second cooling structure 33. When both the first dust removal pipeline assembly 20 and the second dust removal pipeline assembly 30 are in an unusable state, the first valve and the second valve are closed, and the third valve is opened, and the smoke is discharged directly from the standby pipeline 40 and eventually enters the exhaust structure. In the actual production process, it is almost impossible that both the first dust removal pipeline assembly 20 and the second dust removal pipeline assembly 30 cannot be used. The setting of the backup pipeline 40 is only used in an emergency in extreme situations to avoid excessive exhaust gas in the glass kiln that is not discharged and causes excessive air pressure in the kiln. When the backup pipeline 40 is needed, the production of the glass kiln should be stopped in time to reduce the phenomenon of untreated exhaust gas being directly discharged into the atmosphere.
[0041] like Figure 1 As shown, in the technical solution of Example 1, the first dust collection pipeline assembly 20 also includes a first induced draft fan 28, which is arranged on the first dust collection pipeline 21 and is located on the side of the first bag-type dust collection structure 24 close to the second end of the first dust collection pipeline 21. The second dust collection pipeline assembly 30 also includes a second induced draft fan 35, which is arranged on the second dust collection pipeline 31 and is located on the side of the second bag-type dust collection structure 34 close to the second end of the second dust collection pipeline 31. The treated flue gas is directly introduced into the chimney by the first induced draft fan 28 and the second induced draft fan 35 and discharged into the atmosphere. The arrangement of the first induced draft fan 28 and the second induced draft fan 35 can effectively reduce the occurrence of turbulence in the gas path.
[0042] like Figure 6As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the first dust removal pipeline assembly 20 further includes a sixth branch 25. The first end of the sixth branch 25 is located between the first cyclone dust removal structure 22 and the first cooling structure 23 and is connected to the first dust removal pipeline 21. The second end of the sixth branch 25 is located between the second cyclone dust removal structure 32 and the second cooling structure 33 and is connected to the second dust removal pipeline 31. A sixth valve is provided on the sixth branch 25. When the first cyclone dust removal structure 22 is not faulty, but the first cooling structure 23 or the first bag dust removal structure 24 is faulty, the sixth valve can be opened and the air inlet of the first cooling structure 23 can be closed, so that the flue gas flows through the first cyclone dust removal structure 22, the second cooling structure 33 and the second bag dust removal structure 34 for dust removal. The provision of the sixth branch 25 and the sixth valve further reduces the number of times the backup pipeline 40 is used.
[0043] like Figure 6 As shown, in the technical solution of Example 2, the first dust removal pipeline assembly 20 also includes a seventh branch 26. The first end of the seventh branch 26 is located between the first cooling structure 23 and the first bag dust removal structure 24 and is connected to the first dust removal pipeline 21. The second end of the seventh branch 26 is located between the second cooling structure 33 and the second bag dust removal structure 34 and is connected to the second dust removal pipeline 31. A seventh valve is provided on the seventh branch 26. The provision of the seventh branch 26 enables airflow to flow through the first cyclone dust removal structure 22, the first cooling structure 23, and the second bag dust removal structure 34 for dust removal. The provision of the seventh branch 26 and the seventh valve further reduces the number of times the spare pipeline 40 is used.
[0044] like Figure 6 As shown, in the technical solution of Example 2, the first dust removal pipeline assembly 20 further includes an eighth branch 27. The first end of the eighth branch 27 is located between the first bag-type dust removal structure 24 and the exhaust device and is connected to the first dust removal pipeline 21. The second end of the eighth branch 27 is located between the second bag-type dust removal structure 34 and the exhaust device and is connected to the second dust removal pipeline 31. An eighth valve is provided on the eighth branch 27. The provision of the eighth branch 27 allows airflow to flow out of the first induced draft fan 28 or the second induced draft fan 35, avoiding the problem of airflow not being able to flow out normally due to a failure of the first induced draft fan 28 or the second induced draft fan 35.
[0045] The technical solution of Example 2 increases the number of gas path options by providing the sixth branch 25, the seventh branch 26, and the eighth branch 27. It allows users to arbitrarily select either the first cyclone dust removal structure 22 or the second cyclone dust removal structure 32 for removing large-particle impurities, the first cooling structure 23 or the second cooling structure 33 for cooling crystallization, the first bag dust removal structure 24 or the second bag dust removal structure 34 for removing small-particle impurities, and the first induced draft fan 28 or the second induced draft fan 35 for gas exhaust. This further avoids the problem of gas needing to be exhausted through the backup pipeline 40 due to equipment failure in both the first dust removal pipeline assembly 20 and the second dust removal pipeline assembly 30, thereby reducing environmental pollution.
[0046] From the above, it can be seen that the technical solution adopted in this application is composed of a cyclone dust collector (a first cyclone dust removal structure 22 and a second cyclone dust removal structure 32), a multi-tube heat exchanger (a first cooling structure 23 and a second cooling structure 33), a bag dust collector (a first bag dust removal structure 24 and a second bag dust removal structure 34), an induced draft fan (a first induced draft fan 28 and a second induced draft fan 35), a chimney (exhaust equipment) and multiple pipeline valves. The main equipment is evenly divided into two sets, one for use and one for backup (a first dust removal pipeline assembly 20 and a second dust removal pipeline assembly 30). This solution is: the flue gas is sent into the cyclone dust collector through the flue (inlet pipeline 10), most of the particulate matter in the flue gas is filtered and removed, and then the flue gas is cooled to about 110°C through the multi-tube heat exchanger and enters the bag dust collector for dust removal treatment. Finally, the qualified flue gas after treatment by the induced draft fan is discharged into the atmosphere through the chimney, and an additional set of bypass (spare pipeline 40) is added as an emergency backup in case of equipment failure. The 1500℃ kiln flue gas is sent to the dust removal equipment system through the underground flue to supplement the cold air. The temperature of the connected treatment is about 400℃. It is added with a quicklime spraying device through the cyclone dust collector to take away most of the boron-containing sticky substances. The dust removal mechanism makes the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and captured on the wall of the device. Then, the dust particles fall into the ash hopper with the help of gravity. The ash hopper is equipped with an ash discharge valve to discharge ash regularly. After being processed by the cyclone dust collector, it enters the multi-tube heat exchanger to cool the flue gas to about 110℃. The flue gas then enters the bag dust collector for The principle of crystallization treatment is that the filter bag is made of textile filter cloth or non-textile felt, and the dust-laden gas is filtered by the filtering effect of the fiber fabric. When the dust-laden gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. The dust collector hopper is equipped with an ash discharge valve to discharge ash regularly. After being processed by a series of equipment and drawn out by the induced draft fan, the qualified flue gas is discharged into the atmosphere through the chimney. In addition, this method will set the equipment as two parallel systems, adopting a one-in-one standby operation mode to improve the operating stability of the equipment, increase the bypass pipeline to prepare for the simultaneous use of two sets of equipment in case of failure, and ensure the stable operation of the kiln. This technical solution uses a cyclone dust collector and spraying quicklime to remove a large amount of boron-containing sticky substances in the flue gas, which can greatly reduce the viscosity of the flue gas entering the bag dust collector, improve the standard of flue gas emission, reduce the probability of flue gas sticking to the equipment, and reduce the equipment operation and maintenance costs and maintenance frequency.
