Description
Technical Field
[0001] This utility model relates to the field of solid waste treatment technology, and in particular to an integrated device for preparing clean fuel from gasification slag and sludge. Background Technology
[0002] Coal mining brings enormous economic benefits to the country, but the combustion of coal also generates a large amount of gasification ash. Statistics show that Yulin City currently has a cumulative gasification ash volume of approximately 16 million tons, with about 4 million tons generated annually, accounting for over 12% of the city's total industrial solid waste production. With the rapid development of the coal chemical industry, the annual output of gasification ash will exceed 15 million tons, and the increasing emissions have become a significant problem that needs to be addressed. Sludge is an excellent carrier of pathogens. In urban sludge treatment systems, pathogens spread extremely rapidly along with the sewage treatment system. Untreated sludge contains a large number of pathogenic microorganisms and parasite eggs. During sludge treatment and disposal, these pathogens can spread through various routes (such as contaminating soil, air, and water sources), endangering human and animal health through skin contact, respiration, and the food chain, and can also accelerate the spread of plant diseases to some extent.
[0003] Research and experiments have revealed that gasification slag has great potential and broad prospects in thermal energy conversion and agricultural applications. Microorganisms in sludge can stimulate residual carbon in gasification slag; the combination of the two can be used for boiler co-firing to utilize residual carbon in gasification slag, achieving zero ash discharge, zero sludge pollution, and reducing the burden of ash treatment. For example, a clean fuel preparation process using "sludge wall-breaking coupled bio-enzyme catalysis technology" combining gasification slag and sludge (raw sludge—sludge loading equipment—sludge wall-breaking device—conveyor system—mixing device—drying device—granulation—finished product transportation) is possible. However, the sludge treatment process is cumbersome and the output is large. "Sludge wall-breaking coupled bio-enzyme catalysis technology" also requires repeating processes such as disinfection—fermentation—drying. Although biomass catalysis and other related processes can replace disinfection, the catalytic time, temperature, and humidity cannot be uniformly controlled, making it impossible to guarantee the elimination of all pathogens and parasites. Furthermore, the mixing device is a separate process; although the mixing effect can be guaranteed, if it is contaminated by pathogens and harmful substances carried in the first round, it still needs to be disinfected before it can be put into use.
[0004] Therefore, it is necessary to provide an integrated device with a simpler preparation process and the ability to efficiently prepare clean fuels. Utility Model Content
[0005] The purpose of this invention is to provide an integrated device for preparing clean fuel from gasification slag and sludge, so as to solve the problems existing in the prior art. The preparation process is simple and convenient, and it can efficiently prepare clean fuel.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] This utility model provides an integrated device for preparing clean fuel from gasification slag and sludge, including a preparation cylinder, a stirrer, and a disinfection sprayer; the preparation cylinder has a accommodating cavity and an upper inlet and a lower outlet communicating with the accommodating cavity; the accommodating cavity is used to hold gasification slag and sludge, and a discharge valve is provided at the end of the lower outlet; the stirrer has a rotating stirring shaft located inside the accommodating cavity, and stirring blades are provided on the stirring shaft; the disinfection sprayer includes a first fixed seat, a second fixed seat, and a three-in-one pipe; the first fixed seat and the... The second fixing bases are symmetrically fixed on the upper sidewall of the preparation cylinder; each of the first and second fixing bases is provided with three nozzles, each nozzle being located inside the preparation cylinder; the three-in-one pipe includes three independent pipes integrated into an outer pipe, one end of each independent pipe being connected to one nozzle of the first fixing base, and the other end being connected to one nozzle of the second fixing base; each independent pipe is connected to an inlet pipe; lime solution, bleaching powder solution, and chlorine dioxide solution flow through the three independent pipes respectively.
[0008] Preferably, the diameter of the lower discharge port is the same as the inner diameter of the preparation cylinder, and the axis of the lower discharge port forms an angle with the axis of the preparation cylinder.
[0009] Preferably, the upper feed port is a flexible connection port, and the upper feed port is sealed with a sealing cap.
[0010] Preferably, a pH detection probe is also fixedly installed on the inner wall of the preparation cylinder.
[0011] Preferably, the stirrer includes a driver, a stirring shaft, and stirring blades; the driver is fixedly disposed at the upper end of the preparation cylinder, and the output shaft of the driver extends into the preparation cylinder; the stirring shaft is located inside the preparation cylinder, and the stirring shaft is detachably connected to the end of the output shaft of the driver; the stirring blades are fixedly disposed on the stirring shaft.
[0012] Preferably, an inspection port is provided on the side wall of the preparation cylinder, and an inspection door that can be opened and closed is provided at the inspection port.
[0013] Preferably, the stirring blade is a helical blade.
[0014] Preferably, the upper feed port has an internal thread, and the sealing cap has an external thread that is threadedly connected to the internal thread.
[0015] Preferably, a support bracket is also fixedly provided at the lower outer end of the preparation cylinder.
[0016] Preferably, a stabilizing bracket is also fixedly installed inside the preparation cylinder, and the lower end of the stirring shaft is rotatably connected to the stabilizing bracket.
[0017] The present invention achieves the following technical advantages over the prior art:
[0018] This utility model provides an integrated device for preparing clean fuel from gasification slag and sludge. By integrating stirring and disinfection into one unit, its disinfection effect is significantly improved compared to ordinary disinfection processes, ensuring high product mixing uniformity. Lime solution, bleaching powder solution, and chlorine dioxide solution are sprayed from corresponding nozzles through three independent pipes. The three solutions act simultaneously on the gasification slag and sludge mixture in the containment cavity. Lime is used to adjust the pH, while bleaching powder and chlorine dioxide provide powerful sterilization and disinfection, removing harmful microorganisms and parasite eggs from the sludge. Disinfection and conditioning are completed in one stop, reducing process steps. The stirrer ensures uniform disinfection and conditioning effects, eliminating localized inadequate treatment and efficiently advancing the preparation process.
[0019] Furthermore, the diameter of the discharge port is the same as the inner diameter of the preparation cylinder. This large-diameter design greatly reduces the resistance encountered when the material is discharged, thereby ensuring the continuity of the entire preparation process and reducing production stoppages caused by discharge jams. The non-vertical discharge port makes the material retention time distribution in the cylinder more reasonable. Some materials that were originally close to the cylinder wall and had insufficient mixing contact are more likely to be drawn into the core area, reducing the "dead corners" of material retention in the cylinder.
[0020] Furthermore, the flexible connectors allow for easy connection and use at any point during any stage of the production line equipment's operation, reducing docking difficulty and minimizing the need for additional adapters and fitting devices.
[0021] Furthermore, the process of preparing clean fuel from gasification residue and sludge involves numerous chemical reactions, and pH has a crucial impact on the reaction direction and rate. The pH detection probe can monitor the pH of the material inside the cylinder in real time, allowing operators to accurately know the current stage of the reaction. For example, if the pH deviates from the ideal range, it means that the reaction may be abnormal and needs to be adjusted in time to ensure that the entire preparation process strictly follows the established chemical path and allows the generation of clean fuel to proceed stably.
[0022] Furthermore, the stirring shaft and the drive output shaft are detachably connected, allowing staff to easily remove the stirring shaft and stirring blades from the drive output shaft and replace them with new stirring shaft and blade assemblies. This greatly shortens maintenance time, reduces equipment downtime, and ensures that the clean fuel preparation process can quickly resume operation.
[0023] Furthermore, when the equipment malfunctions, maintenance personnel do not need to painstakingly disassemble the entire preparation cylinder. They can quickly locate the fault point simply by opening the inspection door. Through the inspection port, they can directly see the operating status of each component inside the cylinder and directly inspect and test the suspected faulty components. This greatly reduces the time required to troubleshoot, speeds up the maintenance process, reduces equipment downtime, and ensures the continuous and stable production of clean fuel.
[0024] Furthermore, when the helical blades rotate driven by the stirring shaft, they generate an axial thrust, causing the material to move along the stirring shaft direction, preventing local accumulation of material in the preparation cylinder, and allowing the gasification slag and sludge to be fully mixed at different heights within the cylinder. On the other hand, the rotation of the helical blades also causes radial tumbling, causing materials at different radial positions to be drawn into the flow system, breaking the material stratification phenomenon and achieving all-round, three-dimensional uniform mixing. This is extremely crucial for improving the quality and stability of clean fuels, because uniform material mixing is a prerequisite for ensuring the full progress of subsequent reactions.
[0025] Furthermore, the threaded connection can effectively fill gaps and prevent outside air from entering the preparation cylinder, ensuring the stability of the preparation; the threaded connection makes the opening and closing of the sealing cap very precise and controllable, and convenient and quick.
[0026] Furthermore, the gasification slag and sludge themselves have a certain weight. In addition, during the preparation process, the materials are constantly mixed and reacted inside the cylinder, and the entire preparation cylinder bears a large load. The support frame can stably support the preparation cylinder and distribute the weight evenly to the ground, preventing the preparation cylinder from sinking or tilting due to its own excessive weight. This ensures the structural stability of the device during operation, maintains the precise positional relationship of the internal components, and allows processes such as stirring, disinfection, and spraying to continue to operate stably without being affected.
[0027] Furthermore, when the stirring shaft rotates at high speed to stir materials, it will inevitably be subject to material resistance and tend to sway. The stabilizing bracket provides a reliable support point for the lower end of the stirring shaft, forming a stable two-point support structure (the upper end is fixed by the driver, and the lower end is supported by the stabilizing bracket). This greatly limits the radial sway of the stirring shaft, making the stirring blades rotate more precisely and the stirring action more stable. This ensures that the materials can be stirred evenly and avoids insufficient mixing of local materials due to shaft sway, which would affect the quality of the clean fuel.

[0040] Example 1
[0041] This embodiment provides an integrated device for preparing clean fuel from gasification slag and sludge, such as... Figures 1-4As shown, the device includes a preparation cylinder 10, a stirrer, and a disinfection sprayer. The preparation cylinder 10 has a accommodating cavity and an upper inlet 11 and a lower outlet 12 communicating with the accommodating cavity. The accommodating cavity is used to hold gasification slag and sludge, and a discharge valve is provided at the end of the lower outlet 12. The stirrer has a rotating stirring shaft 21 located inside the accommodating cavity, and stirring blades 22 are provided on the stirring shaft 21. The disinfection sprayer includes a first fixed seat 31, a second fixed seat 32, and a three-in-one pipe 30. The first fixed seat 31 and the second fixed seat 32 are symmetrically fixed in the preparation cylinder 10. On the upper side wall of the preparation cylinder 10, three nozzles 302 are provided on both the first fixed seat 31 and the second fixed seat 32, and each nozzle 302 is located inside the preparation cylinder 10; the three-in-one pipe 30 includes three independent pipes 301 integrated in one outer pipe, one end of each independent pipe 301 is connected to one nozzle 302 of the first fixed seat 31, and the other end is connected to one nozzle 302 of the second fixed seat 32; each independent pipe 301 is connected to an inlet pipe; lime solution, bleaching powder solution and chlorine dioxide solution flow through the three independent pipes 301 respectively.
[0042] By integrating mixing and disinfection into one unit, its disinfection effect is significantly improved compared to ordinary disinfection processes, ensuring high uniformity of product mixing. Lime solution, bleaching powder solution, and chlorine dioxide solution are sprayed from corresponding nozzles 302 through three independent pipes 301. The three solutions act simultaneously on the gasified slag and sludge mixture in the containment cavity. Lime is used to adjust the pH, while bleaching powder and chlorine dioxide provide powerful sterilization and disinfection, removing harmful microorganisms and parasite eggs from the sludge. Disinfection and conditioning are completed in one stop, reducing process steps. The mixer ensures uniform disinfection and conditioning effects, eliminating localized inadequate treatment and efficiently advancing the preparation process.
[0043] The following are the relevant settings for the preparation cylinder 10:
[0044] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the upper feed port 11 is a flexible connection port, and a sealing cap 13 is provided at the upper feed port 11. The flexible connection port allows it to be easily connected and used at any point during any period of use of the production line equipment, reducing docking difficulty and minimizing the need for additional adapters and fitting devices.
[0045] In the optional embodiments of this example, it is preferred that the upper feed port 11 has an internal thread, and the sealing cap 13 has an external thread that connects with the internal thread. The threaded connection can effectively fill the gaps, prevent outside air from mixing into the preparation cylinder 10, and ensure the stability of the preparation; the threaded connection makes the opening and closing operation of the sealing cap 13 very precise and controllable, and convenient and quick.
[0046] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, a pH detection probe 14 is also fixedly installed on the inner wall of the preparation cylinder 10. The process of preparing clean fuel from gasification slag and sludge involves numerous chemical reactions, and the pH has a crucial impact on the reaction direction and rate. The pH detection probe 14 can monitor the pH of the material inside the cylinder in real time, allowing operators to accurately know the current stage of the reaction. For example, if the pH deviates from the ideal range, it means that the reaction may be abnormal and needs to be adjusted in time to ensure that the entire preparation process strictly follows the predetermined chemical path and allows the generation of clean fuel to proceed stably.
[0047] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, an inspection port is provided on the side wall of the preparation cylinder 10, and an inspection door 15 that can be opened and closed is provided at the inspection port. When the device malfunctions, maintenance personnel do not need to disassemble the entire preparation cylinder 10. They can simply open the inspection door 15 to quickly locate the fault point. Through the inspection port, the operating status of each component inside the cylinder can be directly observed, and suspected faulty components can be directly inspected and tested. This greatly reduces the time required for troubleshooting, speeds up the maintenance process, reduces equipment downtime, and ensures the continuous and stable production of clean fuel.
[0048] Specifically, the inspection door 15 is equipped with a handle.
[0049] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the diameter of the lower discharge port 12 is the same as the inner diameter of the preparation cylinder 10, and the axis of the lower discharge port 12 forms an angle with the axis of the preparation cylinder 10. This large-diameter design, where the diameter of the lower discharge port 12 is the same as the inner diameter of the preparation cylinder 10, greatly reduces the resistance encountered when the material is discharged, thereby ensuring the continuity of the entire preparation process and reducing production stoppages caused by discharge jams. The non-vertical discharge port makes the material retention time distribution inside the cylinder more reasonable, and some materials that were originally close to the cylinder wall and had insufficient mixing contact are more easily drawn into the core area, reducing the "dead zones" of material retention inside the cylinder.
[0050] The following are the instructions regarding the settings of the mixer:
[0051] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1As shown, the stirrer includes a driver 20, a stirring shaft 21, and stirring blades 22. The driver 20 (such as a drive motor, which is fixed to the upper end of the preparation cylinder 10 via a motor bracket) is fixedly installed at the upper end of the preparation cylinder 10, and the output shaft of the driver 20 extends into the preparation cylinder 10. The stirring shaft 21 is located inside the preparation cylinder 10, and the stirring shaft 21 is detachably connected to the end of the output shaft of the driver 20 (such as by a threaded connection). The stirring blades 22 are fixedly installed on the stirring shaft 21. The stirring shaft 21 and the output shaft of the driver 20 are detachably connected, allowing operators to easily remove the stirring shaft 21 along with the stirring blades 22 from the output shaft of the driver 20 and replace it with a new stirring shaft 21 and blade assembly. This greatly shortens maintenance time, reduces equipment downtime, and ensures that the clean fuel preparation process can be quickly resumed.
[0052] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the stirring blade 22 is a helical blade. When the helical blade rotates driven by the stirring shaft 21, it generates an axial thrust, causing the material to move along the direction of the stirring shaft 21, preventing local accumulation of material in the preparation cylinder 10, and allowing the gasification slag and sludge to be fully mixed at different heights within the cylinder. On the other hand, the rotation of the helical blade also causes radial tumbling, causing materials at different radial positions to be drawn into the flow system, breaking the material stratification phenomenon and achieving all-round, three-dimensional uniform mixing. This is extremely important for improving the quality and stability of clean fuel, because uniform material mixing is a prerequisite for ensuring the full progress of subsequent reactions.
[0053] Regarding other related settings:
[0054] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, a support bracket 16 is also fixedly installed at the lower outer end of the preparation cylinder 10. The gasification slag and sludge themselves have a certain weight. In addition, during the preparation process, the materials are continuously mixed and reacted inside the cylinder, and the entire preparation cylinder 10 bears a large load. The support bracket 16 can stably support the preparation cylinder 10, distribute the weight evenly to the ground, and prevent the preparation cylinder 10 from sinking or tilting due to its own excessive weight. This ensures the structural stability of the device during operation, maintains the precise positional relationship of the internal components, and allows the stirring, disinfection spraying and other processes to be carried out continuously and stably without being affected.
[0055] In the optional embodiments of this example, a more preferred embodiment is that a stabilizing bracket is also fixedly installed inside the preparation cylinder 10, and the lower end of the stirring shaft 21 is rotatably connected to the stabilizing bracket. When the stirring shaft 21 rotates at high speed to stir the material, it will inevitably be subject to the resistance of the material and will tend to shake. The stabilizing bracket provides a reliable support point for the lower end of the stirring shaft 21, forming a stable two-point support structure (the upper end is fixed by the driver 20, and the lower end is supported by the stabilizing bracket), which greatly limits the radial shaking amplitude of the stirring shaft 21, makes the running trajectory of the stirring blade 22 more precise, the stirring action more stable, ensures that the material can be uniformly stirred, and avoids insufficient mixing of local materials due to shaft shaking, which would affect the quality of the clean fuel.
[0056] Specifically, in the three-in-one pipe 30, each independent pipe 301 is evenly distributed around the axis, and its outer pipe is a metal pipe. The end of each independent pipe 301 corresponds to a nozzle 302 with a diameter of 2mm.
[0057] Specifically, the integrated device for preparing clean fuel from gasification slag and sludge in this embodiment can be used independently or in a production line. When the power is turned on, the gasification slag and sludge are mixed and enter from the upper feed port 11. The gasification slag and sludge are thoroughly mixed by the agitator. At the same time, each nozzle 302 intermittently sprays lime solution, bleaching powder solution and chlorine dioxide solution. Each solution is sprayed at a 5-minute interval. Stirring is carried out during spraying. After stirring for 10 minutes, the lower discharge port 12 is opened to complete the discharge.
[0058] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
