Description

Technical Field

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

[0002] In modern industrial production, refractory materials, as key building blocks capable of maintaining stable performance in high-temperature environments, are widely used in numerous high-temperature industries, including metallurgy, building materials, chemicals, and power generation. However, the refractory production process often involves complex physical and chemical changes, inevitably generating large amounts of waste gases with complex compositions and diverse properties. Directly discharging these gases without effective treatment not only severely pollutes the surrounding environment, threatening ecological balance and human health, but also poses environmental compliance risks to businesses and hinders the sustainable development of the industry.

[0003] Most of the exhaust gas from the production process of refractory materials contains a large amount of high-temperature solid particles, acidic gases, etc., so it is usually necessary to cool the exhaust gas first to prevent the high-temperature gas from damaging the equipment. For example, ordinary steel will creep (plastic deformation) when operated for a long time at above 200℃, and its strength will drop by more than 50% at 400℃; the hardness of aluminum alloy decreases significantly above 150℃, causing deformation of structures such as fan impellers and pipe supports; rubber sealing rings (such as fluororubber with a temperature resistance upper limit of about 200℃) age and crack at high temperatures, causing exhaust gas leakage; graphite seals may oxidize and lose at above 500℃, destroying the air tightness of the equipment; conventional filter bags (such as polyester needle-punched felt with a temperature resistance of ≤130℃) will melt and shrink above 200℃. Although the glass fiber filter bag has a temperature resistance of up to 260℃, long-term high temperature (>230℃) will cause the fiber to become brittle and break, and the dust removal efficiency will drop sharply; when the exhaust gas temperature is >250℃, the dust resistivity exceeds the optimal range of electrostatic dust removal (10 4 ~10 11 Ω・cm), the particle charging capacity decreases, and the dust removal efficiency drops from 99% to below 80%; when high-temperature exhaust gas (>150℃) enters the spray tower, the water vapor evaporation rate surges, the solubility of the desulfurizer (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 to clog the filler; at high temperatures, the desorption rate of VOCs (such as benzene series produced by the decomposition of phenolic resin) accelerates, and the activated carbon adsorption capacity decreases by about 15% with every 10℃ increase in temperature. The replacement cycle is shortened from 3 months to 1 week. Technical problems such as these require cooling and initial sedimentation separation of the high-temperature exhaust gas. Currently, when treating high-temperature exhaust gas, the high-temperature exhaust gas is usually first passed into the sedimentation chamber, and tubular fins are set in the sedimentation chamber to contact the exhaust gas to cool and sediment the exhaust gas. However, in actual practice, most tubular fins are static heat exchangers that rely on cooling medium flow regulation, resulting in delayed response and low heat exchange efficiency.

[0028] Reference Figure 1-Figure 7The present invention proposes a waste gas treatment device for refractory material production, including a protective cylinder 1, a cooling cylinder 2 is movably installed in the protective cylinder 1, spherical panels 3 are installed at both ends of the cooling cylinder 2, and the two spherical panels 3 respectively block the openings at both ends of the cooling cylinder 2, a plurality of ventilation pipes 4 are installed in the cooling cylinder 2, and the two ends of the ventilation pipes 4 pass through the two spherical panels 3 respectively. A driving mechanism for driving the cooling cylinder 2 to move is installed in the protective cylinder 1, and a water inlet pipe 7 and a drain pipe 8 are installed on the protective cylinder 1. The water inlet pipe 7 and the drain pipe 8 are both connected to the cooling cylinder 2. In actual conditions, the high-temperature waste gas generated by the production of refractory materials The high-temperature exhaust gas enters from the bottom end of the vent pipe 4, and is cooled in the vent pipe 4. 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 drives the cooling cylinder 2 and multiple vent pipes 4 to perform circular motion. When the vent pipe 4 rotates, the movement trajectory of the gas will be changed, increasing the friction between the particles in the exhaust gas and the inner wall of the vent pipe 4, making it easier for the particles to settle. When the cooling cylinder 2 swings and rotates, the cooling water in the cooling cylinder 2 will also move with the swinging and rotation of the cooling cylinder 2 (the cooling water in the cooling cylinder 2 is not filled). The cooling water is made to move more actively, which can better take away the heat on the ventilation pipe 4, making the heat exchange effect better and being able to cool the high-temperature exhaust gas better. When the cooling cylinder 2 swings and rotates, the cooling water in the cooling cylinder 2 is made more active, and the cooling water washes off the dirt adhering to the outer wall of the ventilation pipe 4, reducing the adhesion of dirt 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 The air pipe 4 causes vibration, which makes it easy to shake off the solid particles adhered to the inner wall of the ventilation pipe 4, further reduce the adhesion of solid particles, and reduce blockage. A top tube 5 is installed on the top of the protective tube 1, and the bottom of the top tube 5 is always against the arc surface of the top spherical panel 3 of the cooling tube 2. A filtering mechanism is installed in the top tube 5, and the top tube 5 is connected to the exhaust pipe 6. After the high-temperature gas is cooled and settled, the exhaust gas after cooling and settling is filtered again through the filtering mechanism. The high-temperature exhaust gas can be cooled and settled pre-treated, and then discharged through the exhaust pipe 6 into subsequent desulfurization and denitrification treatment processes.

[0029] In the above content, when the solid particles settled in the top tube 5 fall down, they may fall on the spherical panel 3 above. However, when the cooling tube 2 swings and rotates, the inner wall of the top tube 5 will limit the movement position of the solid particles. Under the mutual squeezing effect after the accumulation of solid particles, 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.

[0030] like Figure 2 and Figure 6As shown in the figure, the driving mechanism includes a guide block 9, a guide ball 10, a guide vertical rod 11 and a driving assembly; the guide block 9 is fixedly connected to the bottom surface of the ball panel 3 at the bottom of the cooling cylinder 2, and the guide ball 10 is rotatably installed on the guide block 9. One end of the guide vertical rod 11 is fixedly connected to the guide ball 10, and the driving assembly is used to drive the guide vertical rod 11 to perform circular motion. The driving assembly drives the guide vertical rod 11 to perform circular motion. When the guide vertical rod 11 performs circular motion, it will drive the guide ball 10 and the guide block 9 to rotate synchronously. The guide block 9 drives the ball panel 3 below to perform circular motion, and the ball panel 3 drives the cooling cylinder 2 to rotate, thereby realizing the rotation of the cooling cylinder 2.

[0031] like Figure 2 and Figure 6 As shown in the figure, the driving assembly includes a guide motor 12, a driving gear 13, an end face gear ring 14 and a telescopic rod 15; the guide motor 12 is fixedly installed in the protective tube 1, the driving gear 13 is fixedly installed on the output shaft of the guide motor 12, the end face gear ring 14 is rotatably installed in the protective tube 1, and the end face gear ring 14 is engaged with the driving gear 13, the telescopic rod 15 is fixedly installed on the end face gear ring 14, and the output shaft of the telescopic rod 15 is fixedly connected to the guide vertical rod 11. During the specific operation, the guide motor 12 is working, the output shaft of the guide motor 12 drives the driving gear 13 to rotate, the driving gear 13 drives the end face gear ring 14 to rotate, and the rotating end face gear ring 14 drives the telescopic rod 15 and the guide vertical rod 11 to perform circular motion, thereby driving the cooling tube 2 to rotate.

[0032] In actual situations, when the guide motor 12 drives the cooling cylinder 2 to perform circular motion, its motion trajectory is relatively simple, and the cooling water is mainly moved by centrifugal force, and the effect is relatively poor. Therefore, the following design is adopted, and the driving mechanism also includes a guide component; the guide component is used to guide the motion trajectory of the guide vertical rod 11 when performing circular motion, and by changing the motion trajectory of the guide vertical rod 11, the motion trajectory of the cooling cylinder 2 is changed, thereby increasing the movement activity of the cooling water.

[0033] like Figure 2 、 Figure 4 and Figure 6 As shown in the figure, the guide assembly includes a guide plate 16, which is provided with a guide groove 17. The guide vertical rod 11 can slide in the guide groove 17. When the guide vertical rod 11 slides in the guide groove 17, the telescopic rod 15 ensures the change of the movement trajectory of the guide vertical rod 11, thereby facilitating the swinging and rotation of the cooling cylinder 2 and increasing the activity of the cooling water movement.

[0034] like Figure 3 、 Figure 4 and Figure 7As shown in the figure, a floating vibration mechanism is installed on the periphery of the ventilation pipe 4. The cooling water in the cooling cylinder 2 is not filled. When the cooling cylinder 2 moves, the floating vibration mechanism is vibrated by the change of the buoyancy of the cooling water in the cooling cylinder 2 and drives the ventilation 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 periphery of the ventilation 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 is located at the liquid surface of the cooling water in the cooling cylinder 2 and floats up and down. Movement, when the cooling cylinder 2 swings and rotates, the inclination angle of the cooling cylinder 2 will also change accordingly, and the liquid level 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 sinks and floats at the liquid level. When the buoyancy ball 25 sinks and floats, 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 adhered to the inner wall of the vent pipe 4 and reduce the blockage of the vent pipe 4.

[0035] like Figure 2 and Figure 5 As shown in the figure, the filtering mechanism includes a flexible metal filter 18 and a stirring assembly; the flexible metal filter 18 is woven from nickel-titanium alloy wire, and the flexible metal filter 18 is installed in the top tube 5. The stirring assembly is used to stir the flexible metal filter 18, and the flexible metal filter 18 is used to filter the solid particles in the exhaust gas to reduce the amount of solid particles in the exhaust gas and reduce the burden on subsequent processing equipment. The flexible metal filter 18 is driven by the stirring assembly to swing and stir, so that the flexible metal filter 18 is pulled, which facilitates the falling of solid particles adhering to it, thereby ensuring the filtering effect of the flexible metal filter 18.

[0036] like Figure 2 and Figure 5As shown in the figure, the stirring assembly includes a No. 1 fixed block 19, a No. 1 ball 20, a traction telescopic rod 21, a No. 2 ball 22 and a No. 2 fixed block 23; the No. 1 fixed block 19 is fixedly installed on the top inner wall of the top tube 5, the No. 1 ball 20 is rotatably installed on the No. 1 fixed block 19, the traction telescopic rod 21 is fixedly connected to the No. 1 ball 20, the output shaft of the traction telescopic rod 21 passes through the flexible metal filter 18 and is fixedly connected to the flexible metal filter 18, the output shaft end of the traction telescopic rod 21 is fixedly connected to the No. 2 ball 22, and the No. 2 ball 22 is rotatably installed on the No. 2 fixed block 23 On the top, the No. 2 fixed block 23 is fixedly connected to the middle part of the cooling cylinder 2. When the cooling cylinder 2 swings and rotates, it will drive the No. 2 fixed block 23 to swing and rotate synchronously. The No. 2 ball 22 rotates on the No. 2 fixed block 23, and the traction telescopic rod 21 rotates on the No. 1 fixed block 19 through the No. 1 ball 20. The axis of the traction telescopic rod 21 also swings and rotates accordingly, and the output shaft of the traction telescopic rod 21 also swings and rotates accordingly. At the same time, there is a telescopic movement, which can increase the activity of the flexible metal filter 18 and facilitate the shaking off of solid particles adhered to the flexible metal filter 18.

[0037] like Figure 2 and Figure 3 As shown in the figure, when the cooling cylinder 2 is driven to swing and rotate, it is achieved through the following structure: a fixed limit ring 26 is installed on the inner wall of the protective cylinder 1, and a spherical ring 27 is installed on the outer periphery of the cooling cylinder 2. The spherical ring 27 is rotatably installed in the fixed limit ring 26. A connecting channel 30 connected to the cooling cylinder 2 is opened on the spherical ring 27 in the circumferential direction, and a connecting channel connected to 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 sphere, and the cooling cylinder 2 is directly inserted into the sphere, so that the center of the sphere coincides with the center of the swinging rotation of the cooling cylinder 2. It should be noted that during the entire rotation process of the cooling cylinder 2, except for the connecting channel 30 connected to the connecting channel, the remaining connecting channels 30 are all blocked by the fixed limit ring 26, thereby preventing cooling water from overflowing.

[0038] like Figure 1 and Figure 2 As shown in the figure, a bottom tube 28 is installed at the bottom of the protective tube 1, and the top opening of the bottom tube 28 always rests on the outer arc surface of the spherical panel 3 at the lower end of the cooling tube 2. The spherical centers of the two spherical panels 3 at both ends of the cooling tube 2 coincide with the spherical center of the movement of the cooling tube 2. An air intake pipe 29 connected to the bottom tube 28 is installed on the protective tube 1. The high-temperature exhaust gas enters the bottom tube 28 through the air intake pipe 29 and then enters the ventilation pipe 4. The settled solid particles will fall into the bottom tube 28. The discharge of the solid particles is controlled by opening the bottom of the bottom tube 28 and installing a valve; the inner ring of the guide plate 16 is mounted on the bottom tube 28; the end face gear ring 14 is rotatably mounted on the bottom surface of the inner ring of the guide plate 16.

[0039] It should be noted that in the above situation, the bottom end of the top tube 5 always slides against the outer spherical surface of the upper cooling tube 2, and there is a sealing treatment between the two, such as a sealing ring, etc. Similarly, the top end of the bottom tube 28 always slides 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 exhaust gas.

[0040] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
