Description

Technical Field

[0001] This invention relates to a pilot-scale system for the continuous preparation of amorphous coke from raw coal and a one-step continuous coking method, belonging to the fields of flue gas purification material preparation and deep coal processing technology. Background Technology

[0002] Flue gas desulfurization in coal-fired power plants and other industrial processes is a crucial aspect of air pollution control. Current mainstream wet desulfurization technologies suffer from high water consumption, low resource utilization rate of by-product gypsum, and high carbon emissions. Dry desulfurization technology based on porous carbon materials has become a viable alternative due to its advantages such as low water consumption, no secondary pollution, and recoverable sulfur resources. However, the traditional preparation of columnar activated coke requires the addition of large amounts of binders and involves complex processes such as grinding, shaping, and compaction. Furthermore, carbonization and activation must be completed in stages, resulting in high production costs. Additionally, the binders and molding processes can damage the pore structure, leading to high diffusion resistance and poor regeneration performance within the product.

[0003] Amorphous activated carbon requires no binder, eliminating the molding process. Its pore structure is adjustable, offering advantages in both cost and performance. However, its laboratory-scale technology faces bottlenecks during pilot-scale amplification, including difficulty in controlling product performance, poor batch stability, and an inability to balance high performance and low cost. As a result, it has not yet become a mature industrial application technology. Summary of the Invention

[0004] To address the problems existing in the background art, the present invention provides a pilot-scale system for the continuous preparation of amorphous coke from raw coal and a one-step continuous coking method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pilot-scale amplification system for continuous preparation of amorphous coke from raw coal, comprising an intelligent integrated control system for real-time acquisition and closed-loop control of process parameters throughout the entire process, and a simple raw material pretreatment unit connected in sequence for coarse crushing and grading of raw coal and closed temporary storage of qualified raw coal particles, a closed quantitative feeding unit for closed frequency conversion quantitative conveying of qualified raw coal particles, a one-step continuous activation coking main unit for continuous pyrolysis and carbonization of raw coal particles and activation reaction with steam, a continuous coking cooling unit for continuous closed discharge and rapid cooling of high-temperature amorphous coke, and a finished product screening and storage unit for screening, sorting and airtight sealing of finished amorphous coke.

[0006] Furthermore, the simple raw material pretreatment unit includes a raw coal crusher for coarse crushing of raw coal, a grading vibrating screen for classifying and screening qualified raw coal particles, and a sealed raw material storage silo for temporarily storing qualified raw coal particles, which are connected in sequence.

[0007] Furthermore, the sealed quantitative feeding unit is a variable frequency screw sealed feeder connected to the discharge end of the sealed raw material storage silo for adjusting the material conveying rate.

[0008] Furthermore, the main unit of the one-step continuous activation coking process is an integrated continuous coking furnace connected to the discharge end of the variable frequency screw sealed feeder, which is used to integrate the entire process reaction. The integrated continuous coking furnace is divided into the following sections along the material conveying direction: a feed preheating pyrolysis section for removing volatile matter and tar from raw coal, a medium-temperature carbonization and shaping section for building a stable carbon skeleton, a high-temperature activation reaction section for steam countercurrent activation and pore formation, and a discharge slow cooling and pressure stabilization section for stable discharge.

[0009] Furthermore, the one-step continuous activation coking main unit also includes an electric heating component for gradient zone heating of the furnace body, which is installed on the outer wall of the integrated continuous coking furnace and electrically connected to the intelligent integrated control system; an inert gas supply system for providing an inert protective atmosphere, which is connected to the air inlet of the integrated continuous coking furnace and electrically connected to the intelligent integrated control system; a high-temperature steam generation and countercurrent gas distribution system for generating and uniformly countercurrently distributing high-temperature steam, which is connected to the air inlet of the high-temperature activation reaction section of the integrated continuous coking furnace and electrically connected to the intelligent integrated control system; and an in-furnace micro-negative pressure regulating device for maintaining a micro-negative pressure environment inside the furnace, which is connected to the air outlet of the integrated continuous coking furnace and electrically connected to the intelligent integrated control system.

[0010] Furthermore, the continuous coke cooling unit includes a sealed discharge screw conveyor connected to the discharge end of the integrated continuous coking oven for continuous sealed discharge of high-temperature amorphous coke, and a sealed rapid cooling chamber connected to the discharge end of the sealed discharge screw conveyor and electrically connected to the intelligent integrated control system for rapid cooling of the material.

[0011] Furthermore, the finished product screening and sealing unit includes a finished product screening machine connected to the discharge end of the sealed rapid cooling chamber and electrically connected to the intelligent integrated control system for screening and removing broken coke dust and regulating the qualified particle size, and a sealed finished product storage bin connected to the qualified discharge end of the finished product screening machine for sealing qualified finished products in a light-proof and air-isolated manner.

[0012] The present invention discloses a one-step continuous coking method for a pilot-scale system of continuous raw coal preparation of amorphous coke, the method comprising the following steps:

[0013] S1. Select raw coal raw materials, crush and screen them through a simple raw material pretreatment unit to obtain qualified raw coal particles, and temporarily store them in a sealed container.

[0014] S2. Qualified raw coal particles are uniformly fed into the one-step continuous activation coking main unit through a closed quantitative feeding unit.

[0015] S3. Under the protection of inert gas atmosphere in the one-step continuous activation coking main unit, the raw coal particles complete the pyrolysis, carbonization and steam activation reaction in sequence along the material travel direction. The organic matter pyrolysis removal, carbon skeleton construction and multi-level pore construction are completed simultaneously in the one-step continuous activation coking main unit.

[0016] S4. The high-temperature amorphous coke after the reaction is completed is continuously and sealed out through the continuous coke cooling unit and rapidly cooled to the preset safe temperature.

[0017] S5. The cooled material is screened through the finished product screening and sealing unit to remove fine powder and unqualified particles, and qualified amorphous coke products are screened out and sealed for storage, thus completing the entire continuous preparation process.

[0018] Furthermore, the raw coal raw material described in S1 meets the following requirements: fixed carbon ≥ 55%, volatile matter 25%-35%, ash content ≤ 10%, and sulfur content ≤ 1.5%.

[0019] Furthermore, the unshaped coke product described in S5 meets the following requirements: specific surface area ≥ 500 m² / g, pore volume ≥ 0.40 cm³ / g, and mechanical strength ≥ 85%.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention effectively solves the problems of complex preparation processes, high forming costs, high energy consumption of segmented reactions, and difficulties in continuous pilot production of unshaped coke and poor product performance stability of existing activated coke by adopting a technical solution of directly feeding raw coal into the furnace after simple pretreatment. This invention eliminates the grinding, kneading, compaction, and separate preheating and segmented carbonization processes in the traditional activated coke preparation process. It also eliminates the need for binders, significantly simplifying the production process, reducing intermediate material transfer links, and lowering equipment investment and energy consumption. By simultaneously completing the pyrolysis, carbonization, and activation processes within a single furnace, the material is heated more uniformly and in contact with the atmosphere, avoiding the differences in pore structure caused by segmented preparation. This improves upon the shortcomings of traditional activated coke, such as high diffusion resistance and low adsorption site utilization, enhancing product performance and batch consistency. Simultaneously, it enables continuous pilot-scale production of amorphous coke, allowing process parameters to be directly and linearly scaled up to industrial scale, reducing the difficulty of industrialization. The preparation process generates no solid waste, making it environmentally friendly. The resulting product is suitable for industrial flue gas desulfurization conditions and allows for the recovery and utilization of sulfur resources, offering both good environmental and economic benefits.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] A pilot-scale amplification system for the continuous production of amorphous coke from raw coal is disclosed. The entire system lacks independent segmented carbonization and preheating equipment, featuring a simplified structure and high degree of continuity. It includes an intelligent integrated control system 6 for real-time acquisition and closed-loop control of process parameters throughout the entire process; a simple raw material pretreatment unit 1 connected sequentially for coarse crushing and grading of raw coal and temporary storage of qualified raw coal particles in a sealed manner; a sealed quantitative feeding unit 2 for sealed frequency conversion quantitative conveying of qualified raw coal particles; a one-step continuous activation coking main unit 3 for continuous pyrolysis and carbonization of raw coal particles and activation reaction with steam; a continuous coking cooling unit 4 for continuous sealed discharge and rapid cooling of high-temperature amorphous coke; and a finished product screening and storage unit 5 for screening, sorting, and sealed air-isolated storage of the finished amorphous coke.

[0027] The intelligent integrated control system 6 adopts a PLC+DCS integrated control system, which collects operating parameters such as temperature, furnace pressure, inert gas flow rate, steam consumption, and material conveying speed in each section of the one-step continuous activation device in real time, and automatically corrects the process operating parameters to ensure continuous and stable pilot-scale production and high product performance consistency.

[0028] Furthermore, the simple raw material pretreatment unit 1 includes a raw coal crusher 11 for coarse crushing of raw coal, a grading vibrating screen 12 for precise grading and screening of qualified raw coal particles of 3-10mm, and a sealed raw material storage silo 13 for the sealed temporary storage of qualified raw coal particles, which are connected in sequence. It only realizes particle size control, has a simplified structure, and has no drying and modification equipment or powder processing equipment.

[0029] Furthermore, the sealed quantitative feeding unit 2 is a variable frequency screw sealed feeder 21 connected to the discharge end of the sealed raw material storage silo 13 for precisely adjusting the material conveying rate, which is suitable for pilot continuous production capacity of 50-220kg / h, and is sealed throughout the process to prevent oxidation and dust.

[0030] Furthermore, the one-step continuous activation coking main unit 3 is the core integrated equipment of this system, namely the one-step continuous activation device. It is a long-distance single horizontal or vertical integrated continuous coking oven 31 connected to the discharge end of the variable frequency screw closed feeder 21 for integrating the whole process reaction. The integrated continuous coking oven 31 is divided into a feeding preheating pyrolysis section for removing volatile matter and tar from raw coal, a medium-temperature carbonization and shaping section for building a stable carbon skeleton, a high-temperature activation reaction section for steam countercurrent activation and pore formation, and a discharge slow cooling and pressure stabilization section for stable discharge. There is no independent segmented carbonization equipment or independent preheating equipment.

[0031] Feed preheating and pyrolysis section (front section): Corresponding to Figure 2 The drying and preheating zone and pyrolysis reaction zone are at 750-800℃ to remove volatile matter and tar from the raw coal;

[0032] Medium-temperature carbonization and shaping section (before the middle section): 800-880℃, to build a stable carbon skeleton;

[0033] High-temperature activation reaction section (after the middle section): 880~950℃, water vapor countercurrent activation to create pores;

[0034] Discharge slow cooling and pressure stabilization section (later section): Stable discharge, reducing material impact.

[0035] The material moves forward at a uniform speed, the atmosphere flows in the opposite direction, there is no intermediate transfer, and all coking processes are completed in one furnace.

[0036] Furthermore, the one-step continuous activation coking main unit 3 also includes an electric heating component 32 for gradient zone heating of the furnace body, which is installed on the outer wall of the integrated continuous coking furnace 31 and electrically connected to the intelligent integrated control system 6; an inert gas supply system 33 for providing an inert protective atmosphere, which is connected to the air inlet of the integrated continuous coking furnace 31 and electrically connected to the intelligent integrated control system 6; a high-temperature steam generation and countercurrent gas distribution system 34 for generating and uniformly countercurrently distributing high-temperature steam, which is connected to the air inlet of the high-temperature activation reaction section of the integrated continuous coking furnace 31 and electrically connected to the intelligent integrated control system 6; and an in-furnace micro-negative pressure regulating device 35 for maintaining a micro-negative pressure environment in the furnace, which is connected to the air outlet of the integrated continuous coking furnace 31 and electrically connected to the intelligent integrated control system 6. The entire reaction is completed continuously in a single furnace body without the need for transfer and docking of multiple furnace bodies.

[0037] Furthermore, the continuous coking cooling unit 4 can rapidly and gradually cool the high-temperature unshaped coke to a safe storage temperature in a short time, preventing high-temperature oxidation damage to the pore structure. It includes a sealed discharge screw conveyor 41 connected to the discharge end of the integrated continuous coking oven 31 for continuous sealed discharge of high-temperature unshaped coke, and a sealed rapid cooling chamber 42 connected to the discharge end of the sealed discharge screw conveyor 41 and electrically connected to the intelligent integrated control system 6 for rapidly cooling the material to below 100°C.

[0038] Furthermore, the finished product screening and sealing unit 5 includes a finished product screening machine 51 connected to the discharge end of the sealed rapid cooling chamber 42 and electrically connected to the intelligent integrated control system 6, which is used to screen and remove broken coke dust and normalize qualified particles with a diameter of 3-10mm, and a sealed finished product storage chamber 52 connected to the qualified discharge end of the finished product screening machine 51, which is used to seal qualified finished products in a light-proof and air-isolated manner. The finished products are directly sealed and sealed to avoid external water vapor and oxygen from affecting the desulfurization performance of the finished products.

[0039] This invention discloses a one-step continuous coking method for a pilot-scale system of continuous raw coal preparation of amorphous coke. The method employs a one-step continuous integrated coking activation mode, eliminating the need for separate preheating and segmented carbonization processes. The method includes the following steps:

[0040] S1. Select low-rank bituminous coal or lignite as raw coal raw material and crush it coarsely through the raw coal crusher 11 of the simple raw material pretreatment unit 1. After coarse crushing, it is sent to the grading vibrating screen 12 for screening to obtain qualified raw coal particles of 3-10mm and sent to the sealed raw material silo 13 for sealed temporary storage for later use. No binder is added throughout the process, and no grinding, pinching and extrusion molding operations are performed. Only particle size classification is performed. There is no need to perform deep drying and modification pretreatment on the raw coal.

[0041] The raw coal material must meet the following requirements: fixed carbon ≥ 55%, volatile matter 25%-35%, ash content ≤ 10%, and sulfur content ≤ 1.5%.

[0042] S2. The qualified raw coal particles in the sealed raw material silo 13 are uniformly fed into the integrated continuous coking oven 31 of the one-step continuous activation coking main unit 3 through the sealed quantitative feeding unit 2, so as to realize sealed continuous feeding and avoid raw material dust and outside air from entering the oxidizing raw material.

[0043] S3. In the integrated continuous coking furnace 31 of the one-step continuous activation coking main unit 3, under the protection of inert gas and inert atmosphere, the raw coal particles pass through the feeding preheating pyrolysis section, the medium-temperature carbonization and shaping section and the high-temperature activation reaction section in sequence along the material travel direction to complete the entire process of pyrolysis, carbonization and steam activation. The overall reaction temperature range is controlled between 750-950℃. High-temperature saturated steam is used as the activation medium. The steam is accurately and evenly distributed and comes into countercurrent contact with the raw coal material. The overall continuous residence time of the material in the furnace is controlled between 90-180 minutes. There is no need for transfer or segmented discharge and re-entry into the furnace. Through the synergistic effect of gradient zone temperature control of the furnace body, continuous material progress and countercurrent steam distribution, the organic matter pyrolysis removal, carbon skeleton construction and multi-level pore construction are completed simultaneously in the one-step continuous activation coking main unit 3, directly generating qualified unshaped coke semi-finished products.

[0044] S4. The high-temperature amorphous coke after the reaction is completed is continuously and closedly discharged by the closed discharge screw conveyor 41 of the continuous coke cooling unit 4 and sent into the closed rapid cooling chamber 42 for rapid cooling to the preset safe temperature. The material temperature is reduced to below 100℃ by indirect water cooling to terminate the high-temperature reaction and prevent the product surface from oxidizing and deactivating.

[0045] S5. The cooled material is screened by the finished product screening machine 51 of the finished product screening and sealing unit 5 to remove fine powder and unqualified particles, and qualified amorphous coke finished products of 3-10mm are screened out and sent to the sealed finished product storage silo 52 for sealed storage, thus completing the entire continuous preparation process.

[0046] Throughout the pilot production process, the intelligent integrated control system 6 controls the gradient temperature of each zone in the furnace, the flow rate of inert gas, the throughput of steam activator, the material conveying speed, and the micro-negative pressure environment in the furnace in real time, ensuring that the performance of batch products is uniform and stable.

[0047] The finished unshaped coke product meets the following requirements: specific surface area ≥ 500 m² / g, pore volume ≥ 0.40 cm³ / g, and mechanical strength ≥ 85%.

[0048] Example 1

[0049] The raw material selected is lignite, with the following industrial indicators: fixed carbon 58%, volatile matter 32%, ash content 8%, and sulfur content 1.2%.

[0050] Raw coal is crushed and screened to obtain 3-6mm raw coal particles, which are then sent into a one-step continuous activation device in a sealed manner.

[0051] The furnace is temperature-controlled at a gradient of 780-920℃, protected by nitrogen, and activated by high-temperature steam flowing in a counter-current manner. The material is continuously held for 120 minutes.

[0052] After being taken out of the oven, the temperature is quickly cooled to 80°C by air cooling, and after being sieved and sorted, it is sealed and stored.

[0053] Finished product performance: specific surface area 575m² / g, pore volume 0.42cm³ / g, mechanical strength 87%, flue gas desulfurization efficiency 95.2%.

[0054] Example 2

[0055] Low-rank bituminous coal was selected as the raw material. The industrial indicators are: fixed carbon 62%, volatile matter 28%, ash 7%, and sulfur 1.0%.

[0056] Raw coal is crushed and screened to obtain 5-10mm raw coal particles, which are then fed into a one-step continuous activation integrated device at a uniform speed.

[0057] The furnace has a gradient temperature of 800-950℃, a moderate steam flux, and a continuous material residence time of 150 minutes.

[0058] The material is discharged in a sealed container, cooled to 75°C by water, screened to remove impurities, and then sealed for storage.

[0059] Finished product performance: specific surface area 612m² / g, pore volume 0.45cm³ / g, mechanical strength 88.5%, flue gas desulfurization efficiency 94.0%.

[0060] Example 3

[0061] The raw material selected is lignite, with the following industrial indicators: fixed carbon 56%, volatile matter 34%, ash content 8.8%, and sulfur content 1.3%.

[0062] The raw coal particles, which are 4-8mm in size, are screened and then fed into a one-step continuous coking unit.

[0063] The reaction temperature range is 750-900℃, and the continuous residence time is 95 minutes to complete the pyrolysis, carbonization and activation in one integrated process.

[0064] After cooling and sieving, qualified amorphous coke is obtained;

[0065] Finished product performance: specific surface area 545m² / g, pore volume 0.435cm³ / g, mechanical strength 86.5%, flue gas desulfurization efficiency 93.5%.

[0066] like Figure 3 As shown, the desulfurization performance comparison curves between the irregular coke of this invention and the traditional columnar activated coke (under the same flue gas conditions, the same space velocity, and the same regeneration process) are as follows:

[0067] The present invention provides a one-step desulfurization method for 3-10mm unshaped coke, with an initial desulfurization efficiency of 96.5% and a desulfurization efficiency of ≥92% after 10 cycles. The trend shows that the performance decline is gradual and the stability is strong.

[0068] Traditional binder-formed columnar activated coke has an initial desulfurization efficiency of 95%; after 10 cycles, the desulfurization efficiency is ≤83%; the trend is that the activity decreases rapidly, the internal diffusion resistance is high, and the utilization rate is low.
