DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Reference Figures 1-2 , the utility model provides an embodiment: three-dimensional single-roller coal-fired drying furnace with carbon capture function, including drying furnace cabinet 1, drying furnace cabinet 1 one side is provided with hot gas hole 5, drying furnace cabinet 1 is close to hot gas hole 5 one side and is provided with coal-fired furnace 2, coal-fired furnace 2 top is provided with hot gas outlet hole 3, drying furnace cabinet 1 and coal-fired furnace 2 between being provided with gas pipe one 4, coal-fired furnace 2 right side is provided with purification box 7, coal-fired furnace 2 and purification box 7 top are provided with gas hole 9, coal-fired furnace 2 and purification box 7 between being provided with gas pipe two 6, purification box 7 inside is provided with filter layer two 11, filter layer two 11 top is provided with filter layer one 10, filter layer two 11 bottom is provided with filter layer three 12, purification box 7 bottom is provided with exhaust component, and exhaust component includes exhaust pipe 8, exhaust pipe 8 is arranged at purification box 7 bottom, exhaust pipe 8 inside is provided with fan, gas pipe one 4 one end is arranged in hot gas outlet hole 3 inside, and gas pipe one 4 other end is arranged in hot gas hole 5 inside, and gas pipe two 6 both ends are arranged in different gas holes 9 inside;

[0031] Specifically, in the process of drying coal slime and gasification slag, first, we need to generate heat through coal-burning operations in the coal-burning furnace 2. This process not only provides the necessary heat source for drying but also effectively improves the overall system's energy efficiency. The heat released by the combustion process inside the coal-burning furnace 2 first enters the gas delivery pipe one 4 through the hot gas outlet 3, and then the hot gas is introduced into the drying furnace cabinet 1 through the hot gas delivery hole 5, preparing for the subsequent drying process.

[0032] As the temperature in the drying furnace cabinet 1 gradually rises, the provided heat quickly penetrates into the coal slime and gasification slag, ensuring that it can be evenly heated during the drying process and accelerating the evaporation of moisture. At this time, the flue gas generated by the coal-burning furnace 2 will also be discharged through specially designed gas holes. Specifically, the flue gas passes through the gas delivery hole 9 at the top of the coal-burning furnace 2 and is then transmitted to the purification box 7 through the gas delivery pipe two 6.

[0033] The purification process in the purification box 7 is crucial. First, the flue gas passes through the filter layer one 10, which is filled with ceramic particles, serving as a preliminary filtration. Through the filtration of ceramic particles, large-particle pollutants and impurities are effectively removed, ensuring that subsequent processing is not affected. Next, the flue gas enters the filter layer two 11, where the presence of activated carbon allows for the adsorption of harmful gases. The high-efficiency adsorption of activated carbon effectively removes harmful substances, further purifying the flue gas.

[0034] Finally, the purified flue gas flows through the filter layer three 12, where the internal platinum, palladium, and copper-based catalysts further optimize the gas composition through catalytic reactions. This process not only decomposes harmful gases but also converts carbon dioxide into harmless substances, effectively reducing pollutant emissions. After completing these complex purification steps, the flue gas is safely discharged through the exhaust pipe 8, meeting environmental protection requirements and ensuring that the entire drying process is both efficient and environmentally friendly.

[0035] Referring to Figures 3-4 , the drying furnace cabinet 1 is provided with vertical plates 13 on both sides, the vertical plates 13 are provided with bearings 14, the bearings 14 are provided with rotating columns 15, the rotating columns 15 are rotatably connected in the drying furnace cabinet 1, the rotating columns 15 are fixedly connected with rollers 16, and the rollers 16 are fixedly connected with fixed plates 17 on both sides of the outer wall of the rollers 16;

[0036] Specifically, after preheating in the drying furnace cabinet 1, coal slime and gasification slag will be poured into the drying furnace cabinet 1 for drying treatment. At this time, the coal slime and gasification slag will come into contact with the rollers 16 and fixed plates 17 inside the drying furnace cabinet 1. Since the rollers 16 and fixed plates 17 are in a high-temperature environment inside the drying furnace cabinet 1, their surface temperature will not be too low, ensuring that the coal slime and gasification slag can quickly absorb heat in the instant of contact, laying the foundation for the subsequent drying process.

[0037] As the coal slurry and gasification slag rotate under the action of gravity, they will gradually enter the next layer of the dry furnace cabinet 1. Through the transmission of multiple layers of rollers 16 and fixed plates 17, the coal slurry and gasification slag can be uniformly contacted with heat and gradually complete the drying process. This multi-layer design not only improves the drying efficiency, but also ensures that the coal slurry and gasification slag can be completely dried, thereby achieving the ideal drying effect.

[0038] In addition, the rollers 16 and the rotating column 15 are flexibly rotated through the bearing 14. The bearing 14 is very critical, which supports the rotation through the bearing 14 to ensure the stability of the rotation and reduce mechanical wear, thereby prolonging the service life of the equipment. The bearing 14 is cleverly installed in the stand plate 13 away from the high temperature area of the dry furnace cabinet 1, which effectively prevents the high temperature inside the dry furnace cabinet 1 from adversely affecting the stand plate 13.

[0039] Working principle: When the coal slurry and gasification slag need to be dried, we first perform coal burning inside the coal burning furnace 2 to generate heat. The corresponding heat can enter the gas conveying pipe one 4 through the hot gas outlet hole 3, and finally be transmitted to the dry furnace cabinet 1 through the hot gas conveying hole 5. At this time, the dry furnace cabinet 1 is heated by the introduced heat as a preparation before drying. The flue gas generated by burning coal in the coal burning furnace 2 will be transmitted to the purification tank 7 inside the purification tank 7 through the gas conveying pipe two 6 from the gas conveying hole 9 at the top of the purification tank 7. The flue gas will first be preliminarily filtered by the ceramic particles filled in the filter layer one 10 to filter out large particle pollutants and impurities, and then the harmful gas will be adsorbed by the activated carbon in the filter layer two 11. Finally, the gas will be converted into harmless substances by the platinum, palladium, and copper-based catalyst inside the filter layer three 12 through catalytic reaction. Finally, the purified flue gas will be normally discharged through the exhaust pipe 8. After preheating in the dry furnace cabinet 1, the coal slurry and gasification slag are poured into the dry furnace cabinet 1. At this time, the coal slurry and gasification slag will contact the rollers 16 and fixed plates 17 when passing through the positions of the rollers 16 and fixed plates 17. Because the rollers 16 and fixed plates 17 are in a high temperature environment inside the dry furnace cabinet 1, the temperature will not be too low. Therefore, when the coal slurry and gasification slag contact, although they will rotate due to gravity, the multiple layers of rollers 16 and fixed plates 17 can gradually completely dry the coal slurry and gasification slag. The rotating column 15 connected to the roller 16 is flexibly rotated through the bearing 14, and the bearing 14 is arranged in the stand plate 13 away from the dry furnace cabinet 1, which can prevent the high temperature inside the dry furnace cabinet 1 from affecting the stand plate 13.

[0040] It should be explained finally: above only is the preferred embodiment of the utility model and is not used for limiting the utility model, although the utility model has been explained in detail with reference to foregoing embodiment, for the skilled person in the art, it still can modify the technical scheme recorded in foregoing each embodiment or make equivalent replacement to part technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model should be contained in the protection scope of the utility model.
