Description

Technical Field

[0001] This invention relates to the field of dry quenching waste heat coking technology, and in particular to an apparatus and process for coking using dry quenching waste heat. Background Technology

[0002] Dry quenching technology, as one of the core technologies for energy conservation and emission reduction in the coking industry, operates on the principle of using inert gas instead of water in traditional wet quenching. This inert gas exchanges heat with the high-temperature red-hot coke in a cooling furnace. After absorbing the sensible heat of the red-hot coke, the high-temperature inert gas is converted into heat energy for reuse via a waste heat recovery device. This avoids the water waste and environmental pollution caused by wet quenching and achieves cascaded energy utilization. Currently, existing dry quenching waste heat coking devices generally consist of a cooling furnace, blower, waste heat exchanger, filtration mechanism, and conveying equipment. The basic process involves the high-temperature red-hot coke entering the cooling furnace, where inert gas is introduced under the drive of a blower to complete heat exchange. After heat exchange, the high-temperature gas is filtered to remove impurities and then sent to the waste heat exchanger to generate steam for power generation or subsequent coking processes. The cooled red-hot coke is discharged through a conveying system, forming a complete waste heat recovery and coking cycle.

[0003] However, existing dry quenching coke waste heat coking equipment and processes still have many shortcomings in practical applications, which restrict the efficiency of waste heat recovery and the stability of equipment operation. On the one hand, the air intake adjustment of existing equipment mostly relies on manual control or preset programs, which cannot adaptively adjust according to the real-time temperature changes during the cooling process of red coke in the cooling furnace. This easily leads to problems such as insufficient air intake in the initial cooling stage, resulting in slow cooling, and excessive air intake in the later stage, causing energy waste. It may even damage the equipment due to abnormal local temperature rise, disrupt the stability of the temperature field in the furnace, and affect the waste heat recovery effect. On the other hand, the airflow state and interception structure of existing filtration mechanisms are mostly fixed designs, which cannot adapt to the airflow changes caused by fluctuations in air intake. When the air intake is adjusted, the force of the airflow hitting the filter baffle is unstable, which easily leads to insufficient dust interception, secondary dust re-entrainment, or excessive wear of the baffle, reducing dust separation efficiency, shortening equipment lifespan, and also further affecting the stability and efficiency of waste heat exchange due to uneven airflow distribution.

[0014] A process for coking using waste heat from dry quenching, applied to the aforementioned apparatus for coking using waste heat from dry quenching, includes the following steps: A. The high-temperature red coke is transferred to the storage furnace for temporary storage. Once the cooling furnace reaches the feeding conditions, the solenoid valve is opened and the red coke enters the cooling furnace through the solenoid valve. B. The blower delivers the purified inert gas to the air intake regulating mechanism. The thermosensitive drive mechanism automatically adjusts the angle of the rotating plate according to the temperature inside the cooling furnace, controls the overlap of air inlet one and air inlet two, and thus controls the air intake. The inert gas enters the cooling furnace evenly through the air intake pipe. Inside the cooling furnace, the inert gas comes into countercurrent contact with the high-temperature red coke, absorbs the sensible heat of the red coke, and the temperature of the red coke gradually decreases, while the inert gas heats up to become high-temperature inert gas. C. The cooled inert gas, carrying a small amount of coke dust, first enters the primary filtration mechanism. The thermal drive mechanism synchronously adjusts the angle of the arc plate and the rotating baffle according to the temperature in the cooling furnace, so that the high-temperature inert gas automatically generates different vortices on the left side of the primary filtration chamber, so that the impurities in the cooled inert gas can be fully filtered out. D. It is introduced into the waste heat exchanger and exchanges heat with the feedwater in the heat exchanger. The heat of the high-temperature inert gas is transferred to the feedwater, which heats and vaporizes the feedwater to produce medium and high pressure steam. The steam can be directly used for power generation and subsequent coking. E. After heat exchange, the gas is deoxygenated and then filtered a second time by a secondary filter before being sent back into the cooling furnace by a blower to cool the red coke until it is cooled to room temperature. Then, the second solenoid valve is opened, and the gas is discharged through the discharge pipe to the conveyor belt for output and storage.

[0015] The apparatus and process for coking using waste heat from dry quenching provided by this invention have the following advantages: 1. During the initial cooling stage when the hot coke is fed into the cooling furnace, the high temperature acts on the piston chamber, causing the inert gas inside the piston chamber to expand. This expansion drives the piston plate to slide the gear shaft to the right, which in turn drives the first bevel gear to rotate via the first drive gear and the third rotating shaft. The second bevel gear then drives the fourth rotating shaft, which in turn drives the worm gear via the accelerator and worm. Finally, the rotating plate is adjusted to increase the overlapping area of ​​the first and second gas inlets, thereby increasing the air intake inside the cooling furnace. As the hot coke gradually cools, the volume of inert gas inside the piston chamber decreases, causing the rotating plate to gradually rotate back, controlling the air intake to gradually decrease. Through the cooperation of the thermally sensitive drive mechanism and the air intake adjustment mechanism, the air intake of inert gas can be precisely adjusted according to different temperatures inside the cooling furnace. This can quickly suppress abnormal temperature rises, avoid local overheating damage to the equipment, stabilize the temperature field of the storage chamber, and lay the foundation for efficient waste heat recovery in the future.

[0016] 2. When the air intake inside the cooling furnace increases, the drive gear two is driven to rotate simultaneously via the rotating shaft three. In turn, the drive gear three and the rotating shaft two drive the arc plate to rotate, so that the inert gas can form a vortex that gradually decreases as the air intake decreases when it enters the primary filter chamber. Through the cooperation of the primary filter mechanism and the thermally sensitive drive mechanism, the high-temperature inert gas carrying impurities can adaptively adjust its angle to form a variable vortex with the air intake. This keeps the force of the inert gas hitting the fixed baffle and the rotating baffle stable, avoiding insufficient dust interception or wear of the fixed baffle and the rotating baffle caused by air volume fluctuations. At the same time, it improves the uniformity of airflow distribution and effectively improves dust separation efficiency.

[0017] 3. When the vortex of high-temperature inert gas entering the primary filter chamber is large, the drive gear three drives the steel belt pulley two to rotate synchronously through the steel belt pulley one and the transmission steel belt. This, in turn, allows for a large adjustment range of the angle of the rotating baffle through the rotating shaft one. As the vortex decreases, the angle of the rotating baffle gradually decreases until it is level with the fixed baffle. By setting an adjustable angle rotating baffle, the direction of the vortex formed by the arc plate and the change in air intake volume are precisely matched. This ensures that the dust carried by the inert gas always impacts the fixed baffle and the rotating baffle with a stable force. This avoids the dust from escaping due to insufficient airflow, while also preventing excessive wear of the fixed baffle and the rotating baffle or secondary dust re-entrainment due to excessive airflow. This stabilizes the dust interception efficiency and extends the service life of the equipment. Attached Figure Description

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] like Figures 1-9 As shown, this embodiment proposes a coking device utilizing waste heat from dry quenching, including a dry quenching cooling mechanism 10 and a climbing frame 90. A conveying trolley 80 is provided at the upper end of the climbing frame 90. An air intake regulating mechanism 20 is fixedly connected to the lower right end of the dry quenching cooling mechanism 10. A thermally sensitive driving mechanism 40 is fixedly connected to the middle right side of the dry quenching cooling mechanism 10.

A blower 50 is fixedly connected to the right side of the air intake regulating mechanism 20. A secondary filter 70 is fixedly connected to the right end of the blower 50. A waste heat exchanger 60 is fixedly connected to the right end of the secondary filter 70. The upper left end of the waste heat exchanger 60 is connected to the right end of the primary filtration mechanism 30.

[0023] In this embodiment, the dry quenching coke cooling mechanism 10 includes a storage furnace 11. The upper end of the storage furnace 11 is fixedly connected to a feed inlet 12. The lower end of the storage furnace 11 is fixedly connected to a solenoid valve 13. The lower end of the solenoid valve 13 is fixedly connected to a cooling furnace 14. The lower end of the cooling furnace 14 is fixedly connected to a solenoid valve 15. The lower end of the solenoid valve 15 is fixedly connected to a discharge pipe 16. A gas discharge port 17 is provided at the upper right end of the cooling furnace 14.

[0024] Specifically, the high-temperature red coke is transported by a transport vehicle to the lower end of the climbing frame 90. The conveying trolley 80 is then started to transport the high-temperature red coke to the upper end of the feed inlet 12, where it is temporarily stored inside the storage furnace 11. After the cold coke in the cooling furnace 14 is completely drained, solenoid valve 2 15 is closed, and solenoid valve 1 13 is opened to send the high-temperature red coke into the cooling furnace 14. Solenoid valve 1 13 is then closed, and the blower 50 is started to discharge purified inert gas into the cooling furnace 14 to cool the red coke. The cooled gas then passes through a... After primary filtration by the secondary filtration mechanism 30, the gas enters the waste heat exchanger 60 for heat exchange. The heat from the high-temperature inert gas is transferred to the feedwater, causing the feedwater to be heated and vaporized to generate medium- and high-pressure steam. The steam can be directly used for power generation and subsequent coking. After heat exchange, the gas is deoxygenated and then filtered a second time by the secondary filter 70 before being sent back to the cooling furnace 14 by the blower 50 to cool the red coke until it is cooled to room temperature. Then, the second solenoid valve 15 is opened, and the gas is discharged through the discharge pipe 16 onto the conveyor belt for output and storage.

[0025] In this embodiment, the air intake adjustment mechanism 20 includes an air intake 21, a mesh plate 22 is fixedly connected inside the air intake 21, a rotating plate 23 is rotatably connected to the right side of the air intake 21, air inlets 24 are evenly distributed on the outer periphery of the middle part of the rotating plate 23, an air intake pipe 25 is rotatably connected to the right end of the rotating plate 23, and air inlets 26 are evenly distributed on the outer periphery of the left end of the air intake pipe 25.

[0026] In this embodiment, the left end of the air inlet 21 is fixedly connected to the lower right opening of the storage furnace 11, and the right end of the air inlet pipe 25 is fixedly connected to the upper end of the blower 50.

[0027] In this embodiment, the valve adjustment assembly includes a bevel gear 411 and an accelerator 414. The middle part of the bevel gear 411 is fixedly connected to the middle part of the rotating shaft 45. The bevel gear 411 is meshed with a bevel gear 412. The middle part of the bevel gear 412 is fixedly connected to a rotating shaft 413. The lower end of the rotating shaft 413 is fixedly connected to the upper input end of the accelerator 414. The lower output end of the accelerator 414 is fixedly connected to a worm gear 415. The worm gear 415 is meshed with a worm wheel 416. The upper and lower ends of the rotating shaft 413 are rotatably connected to the middle of the rear end of the cooling furnace 14. The left side of the accelerator 414 is fixedly connected to the lower middle part of the right rear end of the cooling furnace 14. The upper and lower ends of the worm gear 415 are rotatably connected to the lower part of the upper rear end of the cooling furnace 14. The inner circumference of the worm wheel 416 is fixedly connected to the outer circumference of the rotating plate 23.

[0028] Specifically, during the initial cooling stage when the red-hot coke is fed into the cooling furnace 14, the high temperature acts on the piston chamber 41, causing the inert gas inside the piston chamber 41 to expand. This expansion drives the gear shaft 43 to slide to the right via the piston plate 42, which in turn drives the bevel gear 411 to rotate via the drive gear 44 and the rotating shaft 45. The bevel gear 412 then drives the rotating shaft 413 to rotate, which in turn drives the worm wheel 416 to rotate via the accelerator 414 and the worm gear 415. Finally, this causes the rotating plate 23 to adjust its angle, allowing the gas inlet 24 and the gas... The increased overlap area of ​​the piston plate 26 increases the air intake inside the cooling furnace 14. As the high-temperature red coke gradually cools down, the volume of inert gas inside the piston chamber 41 decreases, causing the rotating plate 23 to gradually rotate and control the air intake to gradually decrease. Through the cooperation of the thermal drive mechanism 40 and the air intake adjustment mechanism 20, the air intake of inert gas can be precisely adjusted according to different temperatures inside the cooling furnace 14. This can quickly suppress abnormal temperature rises, avoid local overheating damage to equipment, stabilize the temperature field of the storage chamber, and lay the foundation for efficient waste heat recovery in the future.

[0029] In this embodiment, the primary filtration mechanism 30 includes a primary filtration chamber 31. A fixed baffle 32 is fixedly connected to the middle of the upper inner part of the primary filtration chamber 31. A rotating shaft 33 is rotatably connected inside the fixed baffle 32. A rotating baffle 34 is fixedly connected to the outer periphery of the rotating shaft 33. A rotating shaft 35 is rotatably connected to the lower left side of the primary filtration chamber 31. An arc-shaped plate 36 is fixedly connected to the outer periphery of the rotating shaft 35.

[0030] In this embodiment, the left end of the primary filter chamber 31 is fixedly connected to the upper left side of the storage furnace 11, the right end of the primary filter chamber 31 is fixedly connected to the upper left side of the waste heat exchanger 60, and the left end of the arc plate 36 is flush with the lower end of the gas discharge port 17.

[0031] In this embodiment, the thermal drive mechanism 40 includes a valve adjustment assembly and a baffle adjustment assembly. The baffle adjustment assembly includes a piston chamber 41, a piston plate 42 slidably connected to the inner right side of the piston chamber 41, a gear shaft 43 fixedly connected to the right end of the piston plate 42, a drive gear 44 meshing with the gear shaft 43, a rotating shaft 45 fixedly connected to the middle of the drive gear 44, a drive gear 46 fixedly connected to the rear end of the rotating shaft 45, and a drive gear 47 meshing with the drive gear 46. Steel pulley 48 is fixedly connected to the rear end of wheel 3 47. Steel pulley 48 is connected to steel pulley 410 via transmission steel belt 49. Both ends of piston chamber 41 are fixedly connected to the upper inner sides of cooling furnace 14. The middle part of drive gear 3 47 is fixedly connected to the rear end of rotating shaft 2 35. The middle part of steel pulley 2 410 is fixedly connected to the rear end of rotating shaft 1 33. The front and rear ends of rotating shaft 3 45 are rotatably connected to the upper right side of cooling furnace 14. The outer periphery of piston plate 42 is in contact with the inner wall of piston chamber 41.

[0032] Specifically, when the air intake inside the cooling furnace 14 increases, the drive gear 46 rotates synchronously via the rotating shaft 3 45, which in turn drives the arc plate 36 to rotate via the drive gear 3 47 and the rotating shaft 35. This allows the inert gas to form a vortex that gradually decreases as the air intake decreases when it enters the primary filter chamber 31 through the gas discharge port 17 at the upper right end of the cooling furnace 14. Through the cooperation of the primary filter mechanism 30 and the thermally sensitive drive mechanism 40, the high-temperature inert gas carrying impurities can adaptively adjust its angle to form a variable vortex according to the air intake, keeping the force of the inert gas impacting the fixed baffle 32 and the rotating baffle 34 stable. This avoids insufficient dust interception or wear of the fixed baffle 32 and the rotating baffle 34 caused by airflow fluctuations, while also improving the uniformity of airflow distribution and effectively improving dust separation efficiency. When the vortex of high-temperature inert gas entering the primary filter chamber 31 is large, the drive gear 3 47 drives the steel pulley 2 410 to rotate synchronously through the steel pulley 1 48 and the transmission steel belt 49. This, in turn, causes the angle of the rotating baffle 34 to be adjusted by the rotating shaft 33. When the vortex decreases, the angle of the rotating baffle 34 gradually decreases until it is level with the fixed baffle 32. By setting the adjustable angle of the rotating baffle 34, the direction of the vortex formed by the arc plate 36 and the change of air intake are precisely matched. This ensures that the dust carried by the inert gas always impacts the fixed baffle 32 and the rotating baffle 34 with a stable force. This avoids the dust from escaping due to insufficient impact force caused by insufficient air volume, and also prevents excessive wear of the fixed baffle 32 and the rotating baffle 34 or secondary dust re-entrainment caused by excessive air volume. This stabilizes the dust interception efficiency and extends the service life of the equipment.

[0033] A process for coking using waste heat from dry quenching, applied to one of the aforementioned apparatuses for coking using waste heat from dry quenching, includes the following steps: A. The high-temperature red coke is transferred to the storage furnace 11 for temporary storage. After the cooling furnace 14 reaches the feeding conditions, the solenoid valve 13 is opened, and the red coke enters the cooling furnace 14 through the solenoid valve 13. B. The blower 50 delivers the purified inert gas to the air intake regulating mechanism 20. The thermal drive mechanism 40 automatically adjusts the angle of the rotating plate 23 according to the temperature inside the cooling furnace 14, controls the overlap of the first air port 24 and the second air port 26, and thus controls the air intake. The inert gas enters the cooling furnace 14 evenly through the air intake pipe 25. In the cooling furnace, the inert gas comes into countercurrent contact with the high-temperature red coke, absorbs the sensible heat of the red coke, and the temperature of the red coke gradually decreases, while the inert gas heats up to become a high-temperature inert gas. C. The cooled inert gas carries a small amount of coke dust and first enters the primary filtration mechanism 30. The thermal drive mechanism 40 adjusts the angle of the arc plate 36 and the rotating baffle 34 synchronously according to the temperature in the cooling furnace 14, so that the high temperature inert gas automatically generates different vortices on the left side of the primary filtration chamber 31, so that the impurities in the cooled inert gas can be fully filtered out. D. The gas is introduced into the waste heat exchanger 60 to exchange heat with the feedwater in the heat exchanger. The heat of the high-temperature inert gas is transferred to the feedwater, which heats and vaporizes the feedwater to produce medium and high pressure steam. The steam can be directly used for power generation and subsequent coking. E. After heat exchange, the gas is deoxygenated and then filtered a second time by the secondary filter 70. It is then sent back to the cooling furnace 14 by the blower 50 to cool the red coke until it is cooled to room temperature. Then, the solenoid valve 15 is opened and the gas is discharged to the conveyor belt through the discharge pipe 16 for output and storage.

[0034] Working principle: First, high-temperature red-hot coke is transported to the lower end of the climbing frame 90 by a transport vehicle. The conveying trolley 80 is started to transport the high-temperature red-hot coke to the upper end of the feed inlet 12 and send it into the storage furnace 11 for temporary storage. After the cold coke in the cooling furnace 14 is discharged, the second solenoid valve 15 is closed and the first solenoid valve 13 is opened to send the high-temperature red-hot coke into the cooling furnace 14. The first solenoid valve 13 is then closed, and the blower 50 is started to discharge the purified inert gas into the cooling furnace 14 to cool the red-hot coke. The cooled gas is then filtered once by the primary filtration mechanism 30 and enters the waste heat exchanger 60 for heat exchange. The heat from the high-temperature inert gas is transferred to the feedwater, heating and vaporizing the feedwater to produce medium- and high-pressure steam. The steam can be directly used for power generation and subsequent processes. After coking and heat exchange, the gas is deoxygenated and then filtered a second time by a secondary filter 70 before being sent back to the cooling furnace 14 by a blower 50 to cool the red coke until it reaches room temperature. Then, solenoid valve 15 is opened, and the gas is discharged through discharge pipe 16 onto a conveyor belt for output and storage. During the initial cooling stage of the red coke entering the cooling furnace 14, the high temperature acts on the piston chamber 41, causing the inert gas inside to expand. This expansion drives the piston plate 42 to move the gear shaft 43 to the right, which in turn drives the drive gear 44 and the rotating shaft 45 to rotate the bevel gear 411. This, in turn, drives the rotating shaft 413 through the bevel gear 412. Furthermore, the accelerator 414 and the worm gear 415 drive the worm wheel 416 to rotate, finally driving the rotary... The rotating plate 23 is angled to increase the overlapping area of ​​air inlet 1 24 and air inlet 26, thereby increasing the air intake inside the cooling furnace 14. As the high-temperature red coke gradually cools, the volume of inert gas inside the piston chamber 41 decreases, causing the rotating plate 23 to gradually rotate and control the air intake to gradually decrease. Through the cooperation of the thermal drive mechanism 40 and the air intake adjustment mechanism 20, the air intake of inert gas can be precisely adjusted according to different temperatures inside the cooling furnace 14. This can quickly suppress abnormal temperature rises, avoid local overheating damage to the equipment, stabilize the temperature field of the storage chamber, and lay the foundation for efficient waste heat recovery. When the air intake inside the cooling furnace 14 increases, the rotating shaft 3 45 simultaneously drives the drive gear 2 46 to rotate, which in turn drives the drive gear 3 47 and... The rotating shaft 35 drives the arc-shaped plate 36 to rotate, thereby enabling the inert gas to form a vortex that gradually decreases as the air intake decreases when it enters the primary filter chamber 31 through the gas discharge port 17 at the upper right end of the cooling furnace 14. Through the cooperation of the primary filter mechanism 30 and the thermally sensitive drive mechanism 40, the high-temperature inert gas carrying impurities can adaptively adjust its angle to form a variable vortex according to the air intake, keeping the force of the inert gas impacting the fixed baffle 32 and the rotating baffle 34 stable. This avoids insufficient dust interception or wear of the fixed baffle 32 and the rotating baffle 34 caused by airflow fluctuations, while improving the uniformity of airflow distribution and effectively improving dust separation efficiency. When the vortex of the high-temperature inert gas entering the primary filter chamber 31 is large...Drive gear 3 47 synchronously drives steel pulley 2 410 to rotate via steel pulley 1 48 and transmission steel belt 49. This, in turn, rotates baffle 34 via shaft 1 33, allowing for a wide angle adjustment range. As the subsequent vortex decreases, the angle of baffle 34 gradually decreases until it is level with fixed baffle 32. By setting an adjustable-angle baffle 34, precise matching of the vortex direction formed by arc plate 36 with changes in air intake volume is achieved. This ensures that the dust carried by the inert gas consistently impacts fixed baffle 32 and rotating baffle 34 with a stable force. This prevents dust from escaping due to insufficient airflow and excessive wear or secondary dust re-entrainment caused by excessive airflow, thus stabilizing dust interception efficiency and extending equipment lifespan.

10. A process for coking using waste heat from dry quenching, applied to the apparatus for coking using waste heat from dry quenching as described in claim 9, characterized in that, Includes the following steps: A. The high-temperature red coke is transferred to the storage furnace (11) for temporary storage. After the cooling furnace (14) reaches the feeding conditions, the solenoid valve one (13) is opened, and the red coke enters the cooling furnace (14) through the solenoid valve one (13). B. The blower (50) delivers the purified inert gas to the air intake regulating mechanism (20). The thermal drive mechanism (40) automatically adjusts the angle of the rotating plate (23) according to the temperature inside the cooling furnace (14), controls the overlap of the first air port (24) and the second air port (26), and then controls the air intake. The inert gas enters the cooling furnace (14) evenly through the air intake pipe (25). The inert gas comes into countercurrent contact with the high-temperature red coke in the cooling furnace, absorbs the sensible heat of the red coke, and the temperature of the red coke gradually decreases. The inert gas then heats up to become a high-temperature inert gas. C. The cooled inert gas carries a small amount of coke dust and first enters the primary filtration mechanism (30). The thermal drive mechanism (40) adjusts the angle of the arc plate (36) and the rotating baffle (34) synchronously according to the temperature in the cooling furnace (14), so that the high temperature inert gas automatically generates different vortices on the left side of the primary filtration chamber (31), so that the impurities in the cooled inert gas can be fully filtered out. D. It is introduced into the waste heat exchanger (60) to exchange heat with the feed water in the heat exchanger. The heat of the high temperature inert gas is transferred to the feed water, which heats and vaporizes the feed water to produce medium and high pressure steam. The steam can be directly used for power generation and subsequent coking. E. After heat exchange, the gas is deoxygenated and then filtered twice by a secondary filter (70). It is then sent back to the cooling furnace (14) by a blower (50) to cool the red coke until it is cooled to room temperature. Then, the second solenoid valve (15) is opened and the gas is discharged to the conveyor belt through the discharge pipe (16) for output and storage.
