Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to a waste gas treatment device for refractory material production. Background Art

[0002] In the modern industrial production system, refractory materials, as key basic materials that can maintain stable performance in high-temperature environments, are widely used in many high-temperature industrial fields such as metallurgy, building materials, chemical engineering, and electric power. However, the production process of refractory materials is often accompanied by complex physical and chemical changes, inevitably generating a large amount of waste gas with complex compositions and diverse characteristics. If these waste gases are directly discharged without effective treatment, they will not only cause serious pollution to the surrounding environment, threatening ecological balance and human health, but also may lead to environmental compliance risks for enterprises, hindering the sustainable development of the industry.

[0003] Most of the waste gas generated during the production of refractory materials contains a large amount of high-temperature solid particles, acidic gases, etc. Usually, it is necessary to cool the waste gas first to prevent high-temperature gas from damaging the equipment. For example, ordinary steel will creep (plastic deformation) when operating at temperatures above 200°C for a long time, and its strength will decrease by more than 50% at 400°C; the hardness of aluminum alloy will significantly decrease above 150°C, resulting in deformation of structures such as fan impellers and pipeline supports; rubber sealing rings (such as fluororubber with a temperature resistance limit of about 200°C) will age and crack at high temperatures, causing waste gas leakage; graphite seals may oxidize and wear above 500°C, damaging the airtightness of the equipment; conventional filter bags (such as polyester needle felt with a temperature resistance ≤ 130°C) will melt and shrink above 200°C, and although fiberglass filter bags can withstand temperatures up to 260°C, long-term high temperatures (>230°C) will cause the fibers to become brittle and break, resulting in a sharp drop in dust removal efficiency; when the waste gas temperature > 250°C, the dust specific resistance exceeds the optimal range for electrostatic precipitation (10 4 ~10 11 Ω·cm), the particle charging ability decreases, and the dust removal efficiency drops from 99% to below 80%; when high-temperature waste gas (>150°C) enters the spray tower, the water vapor evaporation rate surges, the solubility of desulfurization agents (such as Ca(OH)2) decreases, and the SO2 removal rate drops from 90% to below 60%. At the same time, dry scale is easily formed in the tower, clogging the packing; at high temperatures, the desorption rate of VOCs (such as benzene series substances generated by the decomposition of phenolic resin) increases, and the adsorption capacity of activated carbon decreases by about 15% for every 10°C increase in temperature, and the replacement cycle shortens from 3 months to 1 week. Therefore, it is necessary to cool down and initially settle and separate the high-temperature waste gas. Currently, when treating high-temperature waste gas, usually the high-temperature waste gas is first introduced into a settling chamber, and tubular fins are arranged in the settling chamber to contact the waste gas, playing a role in cooling and settling the waste gas. However, in actual situations, most of the tubular fins are through static heat exchange, relying on the adjustment of the cooling medium flow rate, with a lag in response and low heat exchange efficiency.

Detailed implementation manners

[0018] Refer to Figures 1-7, the present invention provides an exhaust gas treatment device for refractory material production, which includes a protective cylinder 1. Inside the protective cylinder 1, a cooling cylinder 2 is movably installed. Ball panels 3 are installed at both ends of the cooling cylinder 2, and the two ball panels 3 respectively seal the openings at both ends of the cooling cylinder 2. A plurality of ventilation pipes 4 are installed inside the cooling cylinder 2, and both ends of the ventilation pipes 4 respectively penetrate through the two ball panels 3. A driving mechanism for driving the movement of the cooling cylinder 2 is installed inside the protective cylinder 1. A water inlet pipe 7 and a drain pipe 8 are installed on the protective cylinder 1, and both the water inlet pipe 7 and the drain pipe 8 are communicated with the cooling cylinder 2. In actual situations, the high-temperature exhaust gas generated during refractory material production enters from the bottom end of the ventilation pipe 4. The high-temperature exhaust gas is cooled inside the ventilation pipe 4, and at the same time, the gas moves upward. Under the action of gravity, the solid particles in the exhaust gas will settle. At the same time, the driving mechanism works to drive the cooling cylinder 2 and the plurality of ventilation pipes 4 to perform circular motion. When the ventilation pipe 4 rotates, it will change the movement trajectory of the gas, increasing the friction between the particles in the exhaust gas and the inner wall of the ventilation pipe 4, so that the particles are more likely to settle down. When the cooling cylinder 2 swings and rotates, the cooling water inside the cooling cylinder 2 will also move along with the swing and rotation of the cooling cylinder 2 (the cooling water inside the cooling cylinder 2 is not filled to the brim), making the cooling water move more actively, being able to better take away the heat on the ventilation pipe 4, making the heat exchange effect better, and being able to better cool down the high-temperature exhaust gas. When the cooling cylinder 2 swings and rotates, it makes the cooling water inside the cooling cylinder 2 more active, and the cooling water flushes down the scale adhering to the outer wall of the ventilation pipe 4, reducing the adhesion of the scale and ensuring the heat exchange effect. When the ventilation pipe 4 swings and rotates synchronously with the cooling cylinder 2, the ventilation pipe 4 will vibrate, shaking off the particles adhering to the inner wall of the ventilation pipe 4, reducing the adhesion of solid particles. At the same time, the impact of the cooling water on the outer wall of the ventilation pipe 4 can also cause vibration to the ventilation pipe 4, facilitating the shaking off of the solid particles adhering to the inner wall of the ventilation pipe 4, further reducing the adhesion of solid particles and reducing the blockage situation. A top cylinder 5 is installed at the top of the protective cylinder 1, and the bottom of the top cylinder 5 always abuts against the arc surface of the top ball panel 3 of the cooling cylinder 2. A filtering mechanism is installed inside the top cylinder 5, and an exhaust pipe 6 is communicated with the top cylinder 5. After the high-temperature gas is cooled and settled, the cooled and settled exhaust gas is filtered again through the filtering mechanism, and can perform pre-treatment of cooling and sedimentation on the high-temperature exhaust gas, and then be discharged into subsequent processes such as desulfurization and denitrification treatment through the exhaust pipe 6.

[0019] When the solid particles settled inside the top cylinder 5 fall down, they may fall on the upper ball panel 3. However, when the cooling cylinder 2 swings and rotates, the inner wall of the top cylinder 5 will limit the movement position of the solid particles. Under the mutual extrusion effect after the solid particles accumulate, the solid particles are pushed to the top opening of the ventilation pipe 4 and fall down to complete the collection of the solid particles.

[0020] Such as Figure 2 and Figure 6As shown in the figure, the driving mechanism includes a guiding block 9, a guiding ball 10, a guiding vertical rod 11 and a driving component; the guiding block 9 is fixedly connected to the bottom surface of the spherical panel 3 at the bottom of the cooling cylinder 2, the guiding ball 10 is rotatably installed on the guiding block 9, one end of the guiding vertical rod 11 is fixedly connected to the guiding ball 10, and the driving component is used to drive the guiding vertical rod 11 to perform circular motion. When the driving component works to drive the guiding vertical rod 11 to perform circular motion, the guiding vertical rod 11 will drive the guiding ball 10 and the guiding block 9 to rotate synchronously when performing circular motion, and the guiding block 9 will drive the lower spherical panel 3 to perform circular motion, and the spherical panel 3 will drive the cooling cylinder 2 to rotate, realizing the rotation of the cooling cylinder 2.

[0021] As Figure 2 and Figure 6 shown in the figure, the driving component includes a guiding motor 12, a driving gear 13, an end face tooth ring 14 and a telescopic rod 15; the guiding motor 12 is fixedly installed in the protection cylinder 1, the driving gear 13 is fixedly installed on the output shaft of the guiding motor 12, the end face tooth ring 14 is rotatably installed in the protection cylinder 1, and the end face tooth ring 14 meshes with the driving gear 13. The telescopic rod 15 is fixedly installed on the end face tooth ring 14, and the output shaft of the telescopic rod 15 is fixedly connected to the guiding vertical rod 11. In the specific operation process, the guiding motor 12 works, the output shaft of the guiding motor 12 drives the driving gear 13 to rotate, the driving gear 13 drives the end face tooth ring 14 to rotate, and the rotating end face tooth ring 14 drives the telescopic rod 15 and the guiding vertical rod 11 to perform circular motion, thereby driving the cooling cylinder 2 to rotate.

[0022] In actual situations, when the guiding motor 12 drives the cooling cylinder 2 to perform circular motion, its motion trajectory is relatively single, mainly making the cooling water move through centrifugal force, and the effect is relatively poor. Therefore, there is the following design. The driving mechanism also includes a guiding component; the guiding component is used to guide the motion trajectory of the guiding vertical rod 11 when performing circular motion. By changing the motion trajectory of the guiding vertical rod 11, the motion trajectory of the cooling cylinder 2 is changed, increasing the activity of the cooling water movement.

[0023] As Figure 2 、 Figure 4 and Figure 6 shown in the figure, the guiding component includes a guiding disk 16, a guiding groove 17 is formed on the guiding disk 16, the guiding vertical rod 11 can slide in the guiding groove 17. When the guiding vertical rod 11 slides in the guiding groove 17, the telescopic rod 15 ensures the change of the motion trajectory of the guiding vertical rod 11, thereby facilitating the swinging rotation of the cooling cylinder 2 and increasing the activity of the cooling water movement.

[0024] As Figure 3 、 Figure 4 and Figure 7As shown in the figure, a floating vibration mechanism is installed on the outer periphery of the vent pipe 4. The cooling water in the cooling cylinder 2 is not filled to the brim. When the cooling cylinder 2 moves, the floating vibration mechanism vibrates due to the change in the buoyancy of the cooling water in the cooling cylinder 2 and drives the vent pipe 4 to vibrate. The floating vibration mechanism includes a connecting block 24 and a buoyancy ball 25. The connecting block 24 is fixedly connected to the outer periphery of the vent pipe 4, and the buoyancy ball 25 is fixedly installed on the connecting block 24. When the cooling cylinder 2 moves in the protective cylinder 1, the buoyancy ball 25 floats and sinks at the liquid level of the cooling water in the cooling cylinder 2. When the cooling cylinder 2 swings and rotates, the inclination angle of the cooling cylinder 2 will also change accordingly, and the liquid level height in the cooling cylinder 2 will also change accordingly. At the same time, the height of the buoyancy ball 25 on the connecting block 24 will also change accordingly, so that the buoyancy ball 25 floats and sinks at the liquid level position. When the buoyancy ball 25 floats and sinks, its buoyancy changes, and the buoyancy ball 25 will cause vibration to the connecting block 24 and the vent pipe 4, which can better shake off the particles adhering to the inner wall of the vent pipe 4 and reduce the occurrence of blockage of the vent pipe 4.

[0025] As Figure 2 and Figure 5 shown in the figure, the filtering mechanism includes a flexible metal filter screen 18 and a stirring component. The flexible metal filter screen 18 is woven from nickel-titanium alloy metal wires. The flexible metal filter screen 18 is installed in the top cylinder 5. The stirring component is used to stir the flexible metal filter screen 18. When the flexible metal filter screen 18 filters the solid particles in the waste gas again, the amount of solid particles in the waste gas is reduced, and the burden on the subsequent treatment equipment is reduced. By driving the flexible metal filter screen 18 to swing and stir through the stirring component, the flexible metal filter screen 18 is pulled, which facilitates the falling of the solid particles adhering to it and ensures the filtering effect of the flexible metal filter screen 18.

[0026] As Figure 2 and Figure 5As shown in the figure, the stirring assembly includes a first fixed block 19, a first spherical ball 20, a traction telescopic rod 21, a second spherical ball 22 and a second fixed block 23. The first fixed block 19 is fixedly installed on the inner wall of the top of the top cylinder 5. The first spherical ball 20 is rotatably installed on the first fixed block 19. The traction telescopic rod 21 is fixedly connected to the first spherical ball 20. The output shaft of the traction telescopic rod 21 penetrates through the flexible metal filter screen 18 and is fixedly connected to the flexible metal filter screen 18. The end of the output shaft of the traction telescopic rod 21 is fixedly connected to the second spherical ball 22. The second spherical ball 22 is rotatably installed on the second fixed block 23. The second fixed block 23 is fixedly connected to the middle of the cooling cylinder 2. When the cooling cylinder 2 swings and rotates, it will drive the second fixed block 23 to swing and rotate synchronously. The second spherical ball 22 rotates on the second fixed block 23. The traction telescopic rod 21 rotates on the first fixed block 19 through the first spherical ball 20. The axis of the traction telescopic rod 21 also swings and rotates accordingly. The output shaft of the traction telescopic rod 21 will also follow and swing and rotate, and at the same time there is also a telescopic movement, which can increase the activity of the flexible metal filter screen 18 and facilitate shaking off the solid particles adhered to the flexible metal filter screen 18.

[0027] As Figure 2 and Figure 3 shown in the figure, when driving the cooling cylinder 2 to swing and rotate, it is realized through the following structure. A fixed limit ring 26 is installed on the inner wall of the protective cylinder 1. A spherical ring 27 is sleeved on the outer circumference of the cooling cylinder 2. The spherical ring 27 is rotatably installed in the fixed limit ring 26. A communication channel 30 communicating with the inside of the cooling cylinder 2 is circumferentially opened on the spherical ring 27. An access channel communicating with the water inlet pipe 7 and the drain pipe 8 is opened on the fixed limit ring 26. In the specific operation process, the spherical ring 27 is a spherical ball, and the cooling cylinder 2 is directly inserted into the spherical ball, so that the center of the spherical ball coincides with the center of the swing rotation of the cooling cylinder 2. It should be noted that during the entire rotation process of the cooling cylinder 2, except for the communication channel 30 communicating with the access channel, the remaining communication channels 30 are blocked by the fixed limit ring 26, so as to avoid the overflow of cooling water.

[0028] As Figure 1 and Figure 2 shown in the figure, a bottom cylinder 28 is installed at the bottom of the protective cylinder 1. The top opening of the bottom cylinder 28 always abuts against the outer arc surface of the lower spherical panel 3 of the cooling cylinder 2. The centers of the two spherical panels 3 at both ends of the cooling cylinder 2 coincide with the center of the movement of the cooling cylinder 2. An air inlet pipe 29 communicating with the bottom cylinder 28 is installed on the protective cylinder 1. High-temperature waste gas enters the bottom cylinder 28 through the air inlet pipe 29 and then enters the ventilation pipe 4. The settled solid particles will fall into the bottom cylinder 28, and the discharge of solid particles is controlled by opening and installing a valve at the bottom of the bottom cylinder 28; the inner ring part of the guiding disk 16 is sleeved on the bottom cylinder 28; the end face gear ring 14 is rotatably installed on the bottom surface of the inner ring part of the guiding disk 16.

[0029] It should be noted that in the above situation, the bottom end of the top cylinder 5 always slides and abuts against the outer spherical surface of the upper cooling cylinder 2, and there is a sealing treatment between the two, such as a sealing ring, etc. Similarly, the top end of the bottom cylinder 28 always slides and abuts against the outer spherical surface of the lower spherical panel 3, and there is also a sealing treatment between the two to reduce the leakage of waste gas.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
