Description

Technical Field

[0001] This application relates to the field of coke powder recovery technology, and in particular to a coke powder recovery device for a wet quenching tower based on a track-guided and slag-flushing system. Background Technology

[0002] Against the backdrop of the current green transformation of the coking industry, wet quenching technology still holds a dominant position in the industry due to its relatively low equipment investment cost and high operational stability. However, it is undeniable that this technology has exposed many thorny problems in actual operation, especially in coke powder recovery and environmental governance, which have become key issues restricting the further development of the industry and are awaiting breakthrough solutions.

[0003] In the traditional wet quenching tower's bottom track area, coke dust deposition is extremely severe. Without a scientifically sound flow design, the coke dust generated during quenching accumulates in large quantities around the track. This coke dust gradually forms a hardened layer, severely impacting the track's geometry and causing deviations in its flatness and straightness. This significantly threatens the stability and safety of the quenching car's operation, potentially leading to derailment and other malfunctions, greatly increasing equipment maintenance costs and the risk of production interruptions.

[0004] In traditional wet quenching processes, manual cleaning of coke powder has significant drawbacks. It is inefficient, with several tons of coke powder accumulating on the bottom tracks of large wet quenching towers every day. The cleaning speed is far slower than the accumulation speed, and there are also prominent safety hazards. The bottom environment is hot and humid and filled with harmful gases, making workers susceptible to respiratory diseases or even poisoning. The narrow tracks also pose a risk of collision with the quenching cars. In addition, the recovery effect is poor. Due to the difficulty in accurately controlling the cleaning force and scope, more than 40% of coke powder remains in the gaps of the tracks, affecting track stability, increasing equipment failures, and causing resource waste, resulting in a low coke powder recovery rate. Utility Model Content

[0005] To address the problem of low efficiency in manual coke dust removal, this application provides a coke dust recovery device for wet quenching towers based on a track-guided and slag-flushing system.

[0006] The technical solution provided in this application for a wet quenching tower coke powder recovery device based on a track-guided and slag-flushing system is as follows:

[0007] A coke powder recovery device for a wet quenching tower based on a track-guided and slag-flushing system includes a recovery base arranged below the quenching car's running track. Several guide plates are arranged on the recovery base below the quenching car's running track. Several guide holes are opened below the running track. Several flushing branch pipes are arranged on one side of each guide plate, facing the guide plates. A water supply mechanism is provided for all flushing branch pipes. A circulating water tank is provided on the recovery base, located on the side of the guide plates away from the flushing branch pipes.

[0008] In traditional wet quenching processes, manual cleaning of coke powder has significant drawbacks. It is inefficient, with tons of coke powder accumulating daily on the bottom tracks of large wet quenching towers. The cleaning speed is far slower than the accumulation rate, and safety hazards are prominent. The bottom environment is hot and humid, filled with harmful gases, making workers susceptible to respiratory illnesses and even poisoning. The narrow tracks also pose a risk of collision with the quenching car. Furthermore, the recovery effect is poor; due to the difficulty in accurately controlling the cleaning force and scope, over 40% of coke powder remains in track gaps, affecting track stability, increasing equipment failures, and wasting resources, resulting in a low coke powder recovery rate. The proposed technical solution, including a recovery base with several guide plates installed on it, the quenching car's running track mounted on the guide plates, guide holes on the running track, flushing branch pipes installed on one side of the guide plates, and a circulating water tank installed on the recovery base, addresses these issues.

[0009] After the coke quenching car completes the preliminary work such as receiving coke, it smoothly enters the wet quenching tower along the predetermined running track. At this time, the entire coke powder recovery device is in standby mode, waiting to be started to deal with the subsequent coke powder cleaning and sewage collection work. The water supply mechanism supplies water, and the water body sprays out from the flushing branch pipe towards the guide plate to form a fan-shaped jet of water, which accurately flushes the coke powder attached to the track area at the bottom of the wet quenching tower. The flushing water carries the flushed coke powder and flows along the guide plate. Turbulent zones are formed on both sides and in the middle of the running track, and the quenching sewage mixed with coke powder is introduced into the circulating water tank through the guide hole. The circulating water tank collects and processes the wastewater.

[0010] By incorporating baffles, guide holes, flushing branch pipes, and circulating water tanks, efficient and automated cleaning is achieved. This system can precisely flush away coke powder in the track area, solving the problem of difficulty in controlling the force and scope of manual cleaning. It can efficiently guide wastewater containing mixed coke powder into the circulating water tank for collection and treatment through the guide holes, effectively preventing coke powder from accumulating around the track, ensuring track stability, reducing equipment failures, and improving the coke powder recovery rate. This enables the rational recycling of resources, reduces manual cleaning costs and environmental pollution risks, and provides strong support for clean production in the coking industry.

[0011] Optionally, the water supply mechanism includes a circulating water tank, a booster pump, and a delivery pipeline. One end of the delivery pipeline is connected to the circulating water tank, and the other end of the delivery pipeline is connected to the inlet of the booster pump. The outlet of the booster pump is connected to several flushing branch pipes.

[0012] By adopting the above technical solution, the water supply mechanism includes a circulating water tank, a booster pump, and a delivery pipeline. Through the setting of the water supply mechanism, a stable delivery and pressurized supply of water is achieved. The circulating water tank serves as a water source reserve, ensuring the continuous operation of the flushing operation. The booster pump pressurizes the water, giving the water flow sufficient power to ensure that the fan-shaped jet of water sprayed from the flushing branch pipe can accurately and powerfully flush away the coke powder in the track area, effectively improving the coke powder cleaning effect.

[0013] Optionally, the water supply mechanism further includes a flushing main pipe, and several flushing branch pipes are connected to the flushing main pipe, with the outlet of the booster pump connected to the flushing main pipe.

[0014] By adopting the above technical solution, the water supply mechanism also includes a flushing main pipe. The water in the circulating water tank serves as the flushing water source. Under the action of the booster pump, the water pressure is increased. The booster pump continues to operate, raising the water pressure to the standard required for flushing operations. The pressurized water is then transported to the high-pressure flushing main pipe through a delivery pipeline. Several flushing branch pipes are connected to the high-pressure flushing main pipe. When the water reaches the flushing branch pipes, it is sprayed out at high speed from the flushing branch pipe openings, forming a fan-shaped jet of water. Through the setting of the flushing main pipe, the high-pressure flushing main pipe plays the role of converging and stabilizing the pressurized water flow, ensuring the balance of water pressure and flow rate in each flushing branch pipe, and ensuring that the fan-shaped jet of water can stably, accurately, and powerfully flush away coke powder in the track area, significantly improving the effect and efficiency of coke powder cleaning.

[0015] Optionally, several of the flushing branch pipes are distributed at equal intervals along the running track direction.

[0016] By adopting the above technical solution, several flushing branch pipes are distributed at equal intervals along the running track. By setting the position of the flushing branch pipes, the flushing branch pipes can form a uniform and orderly layout under the track, ensuring that each section of the track area can be accurately covered, achieving comprehensive and thorough cleaning of coke powder, significantly improving the flushing effect and efficiency, and reducing coke powder residue.

[0017] Optionally, the outlet end of any of the flushing branch pipes is inclined toward the direction of the running track, and the outlet end of the flushing branch pipe forms a 45° angle with the plane of the running track.

[0018] By adopting the above technical solution, the water outlet of the flushing branch pipe forms a 45° angle with the plane of the running track. By setting the angle of the flushing branch pipe, the 45° angle allows the water jet from the flushing branch pipe to impact the track surface at a suitable angle, forming effective component forces in the horizontal and vertical directions. This ensures that the water jet has sufficient horizontal force to move the coke powder, and also enhances the water jet's ability to peel off the coke powder from the track surface with the help of the vertical component force, thereby greatly improving the flushing effect on the coke powder and significantly reducing coke powder residue.

[0019] Optionally, any of the aforementioned guide vanes has a triangular prism-like structure, and adjacent guide vanes are sequentially and tightly spliced ​​together along the length of the running track.

[0020] By adopting the above technical solution, the guide plates are all in the form of a triangular prism structure, and adjacent guide plates are closely spliced ​​together along the length of the running track. Through the design of the guide plate shape, the unique triangular prism shape gives its surface a natural slope. When the coke powder washed down reaches the guide plate with the water flow, it can slide down quickly along the inclined surface, and it is not easy to accumulate on the guide plate, thus ensuring the smooth flow of the guide plate surface. This ensures that the slag flushing water carrying the coke powder can flow continuously and smoothly along the guide plate.

[0021] Optionally, several embedded latches are provided between the splicing ends of adjacent guide plates.

[0022] By adopting the above technical solution, the splicing ends of adjacent guide plates are fixed by embedded latches. The embedded latches can effectively enhance the connection strength and stability of the splicing of the guide plates, and prevent the guide plates from loosening, shifting or even falling off under long-term water flow scouring and coke powder friction, thus ensuring the overall structural integrity of the guide system.

[0023] Optionally, the surface of any of the baffles is coated with a hydrophobic coating to prevent the adhesion of slag powder.

[0024] By adopting the above technical solution, a hydrophobic coating is applied to the surface of the guide plate. The hydrophobic coating effectively prevents coke powder from adhering to the guide plate, greatly reducing the accumulation of coke powder on the surface of the guide plate, ensuring the cleanliness and smooth flow of the guide plate surface, and ensuring that the flushing water carrying coke powder can flow continuously and efficiently.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up guide plates, guide holes, flushing branch pipes and circulating water tanks, efficient and automated cleaning is achieved. It can accurately flush coke powder in the track area, solving the problem of difficulty in controlling the force and scope of manual cleaning. It can efficiently guide the wastewater mixed with coke powder into the circulating water tank for collection and treatment through the guide holes, effectively preventing coke powder from accumulating around the track, ensuring track stability, reducing equipment failure, improving the coke powder recovery rate, realizing the rational recycling of resources, reducing manual cleaning costs and environmental pollution risks, and providing strong support for clean production in the coking industry.

[0027] 2. By designing the shape of the baffle, the unique triangular prism shape gives its surface a natural slope. When the coke powder washed down reaches the baffle with the water flow, it can slide down quickly along the inclined surface, making it less likely to accumulate on the baffle. This ensures the smooth flow of the baffle surface, thereby ensuring that the flushing water carrying the coke powder can flow continuously and smoothly along the baffle.

[0028] 3. By setting the hydrophobic coating, the hydrophobic coating effectively prevents coke powder from adhering to the guide plate, greatly reducing the accumulation of coke powder on the surface of the guide plate, ensuring the cleanliness and smooth flow of the guide plate surface, and ensuring that the flushing water carrying coke powder can flow continuously and efficiently.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This application discloses a coke powder recovery device for a wet quenching tower based on a track-guided and slag-flushing system. (Refer to...) Figure 1 The wet quenching tower coke powder recovery device based on track guidance and slag flushing system includes a recovery base 2, which in this embodiment is located below the quenching car running track 1.

[0034] Reference Figure 1Several guide plates 3 are installed on the recovery base 2. The guide plates 3 are arranged in sequence below the coke quenching car travel track 1. Each guide plate 3 has a triangular prism-like structure. Adjacent guide plates 3 are closely spliced ​​together along the length of the travel track 1. In this embodiment, the bottom of the travel track 1 is formed with a groove that matches the shape of the guide plate 3. At the same time, several guide holes 4 are opened through the bottom of the travel track 1. The unique shape of the triangular prism gives its surface a natural slope. When the coke powder washed down reaches the guide plate 3 with the water flow, it can slide down quickly along the inclined surface and is not easy to accumulate on the guide plate 3, which ensures the smooth flow of the surface of the guide plate 3. This ensures that the slag flushing water carrying the coke powder can flow continuously and smoothly along the guide plate 3.

[0035] Reference Figure 1 Several embedded latches 8 are installed between the splicing ends of adjacent guide plates 3; the embedded latches 8 can effectively enhance the connection strength and stability of the splicing of guide plates 3, and prevent the guide plates 3 from loosening, shifting or even falling off under long-term water flow scouring and coke powder friction, thus ensuring the overall structural integrity of the guide system.

[0036] Reference Figure 1 Furthermore, each guide plate 3 is coated with a hydrophobic coating, which can be polytetrafluoroethylene (PTFE). The hydrophobic coating effectively prevents coke powder from adhering to the guide plate 3, greatly reducing the accumulation of coke powder on the surface of the guide plate 3, ensuring the cleanliness and smooth flow of the guide plate 3 surface, and ensuring that the flushing water carrying coke powder can flow continuously and efficiently.

[0037] Reference Figure 1 A circulating water tank 7 is formed on the recycling base 2. The circulating water tank 7 is arranged on one side of the guide plate 3. At the same time, several flushing branch pipes 5 are installed on the side of the guide plate 3 away from the circulating water tank 7. The flushing branch pipes 5 are distributed at equal intervals along the direction of the running track 1. The water outlet of each flushing branch pipe 5 is inclined towards the direction of the running track 1. The water outlet of the flushing branch pipe 5 forms a 45° angle with the plane of the running track 1. The 45° angle allows the water flow sprayed from the flushing branch pipe 5 to impact the track surface at a suitable angle, forming an effective component force in the horizontal and vertical directions. This ensures that the water flow has sufficient horizontal force to push the coke powder to move, and also enhances the water flow's ability to peel off the coke powder from the track surface with the help of the vertical component force, thereby greatly improving the flushing effect on the coke powder and significantly reducing coke powder residue.

[0038] Reference Figure 1 and Figure 2A water supply mechanism 6 is installed between several flushing branch pipes 5. The water supply mechanism 6 is used to supply water to the flushing branch pipes 5. The water supply mechanism 6 includes a circulating water tank 61, a booster pump 62, a delivery pipeline 63 and a flushing main pipe 64. The circulating water tank 61 is located outside the recovery base 2 and stores water. One end of the delivery pipeline 63 is connected to the circulating water tank 61, and the other end of the delivery pipeline 63 is connected to the water inlet of the booster pump 62.

[0039] Reference Figure 1 and Figure 2 The flushing main pipe 64 is arranged between the pressurizing pump 62 and several flushing branch pipes 5. All flushing branch pipes 5 are connected to the flushing main pipe 64. The water outlet of the pressurizing pump 62 is connected to the flushing main pipe 64. In this embodiment, the flushing main pipe 64 can be equipped with a corresponding support structure. The flushing main pipe 64 plays the role of converging and stabilizing the pressurized water flow, ensuring the balance of water pressure and flow rate of each flushing branch pipe 5, and ensuring that the fan-shaped jet water flow can stably, accurately and powerfully flush the coke powder in the track area, significantly improving the effect and efficiency of coke powder cleaning.

[0040] The implementation principle of the wet quenching tower coke powder recovery device based on track guidance and slag flushing system in this application embodiment is as follows: After the quenching car completes the pre-operational work such as receiving coke, it smoothly enters the wet quenching tower along the predetermined travel track 1. At this time, the entire coke powder recovery device is in standby mode, waiting to be started to deal with the subsequent coke powder cleaning and sewage collection work. The water in the circulating water tank 61 serves as the flushing water source. Under the action of the pressurization pump 62, the water pressure begins to increase. The pressurization pump 62 continues to operate, raising the water pressure to the standard that meets the requirements of the flushing operation. After pressurization... The water is then transported to the main flushing pipe 64 via the conveying pipeline 63. Several flushing branch pipes 5 are connected to the main flushing pipe 64. When the water reaches the flushing branch pipe 5, it is sprayed out at high speed from the flushing branch pipe 5, forming a fan-shaped jet of water. This jet accurately flushes the coke powder adhering to the track area at the bottom of the wet quenching tower. The flushing water carries the flushed coke powder and flows along the guide plate 3. Turbulent zones are formed on both sides and in the middle of the running track 1. The quenching wastewater mixed with coke powder is introduced into the circulating water tank 7 through the guide hole 4. The circulating water tank 7 collects and performs subsequent treatment.

[0041] By setting up the guide plate 3, guide hole 4, flushing branch pipe 5 and circulating water tank 7, efficient and automated cleaning is achieved. It can accurately flush coke powder in the track area, solving the problem of difficulty in controlling the force and range of manual cleaning. It can efficiently guide the wastewater mixed with coke powder into the circulating water tank 7 for collection and treatment through the guide hole 4, effectively preventing coke powder from accumulating around the track, ensuring track stability, reducing equipment failure, improving the coke powder recovery rate, realizing the rational recycling of resources, reducing the cost of manual cleaning and the risk of environmental pollution, and providing strong support for clean production in the coking industry.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
