Abstract
Description
Technical Field
[0001] This invention relates to the field of catalyst activation technology, and in particular to a catalyst activation device. Background Technology
[0002] Catalysts are substances that can change the rate of a chemical reaction while maintaining their chemical properties and mass before and after the reaction. They are widely used in chemical, environmental protection, and energy fields. Their core function is to reduce the activation energy of a reaction and improve reaction efficiency and selectivity. Common catalyst materials include metal oxides, noble metals, and magnetic composite materials. When these materials are first prepared, the active components are mostly in an inert state with no effective active sites on the surface, so they cannot exert a catalytic effect. Therefore, activation devices are needed to activate their catalytic performance and give the material stable catalytic activity to meet the requirements of subsequent reactions.
[0003] For example, Chinese patent CN210675228U discloses a catalyst carrier activation device, including an activation tank, a hot air blower, an air duct, an air outlet, a temperature sensor, a motor, a tilting shaft, and a tilting plate. The device uses the tilting plate and stirring rod to tilt and stir the material in the activation tank, so that the material can be heated evenly. However, it only relies on the hot air blower as a single heating source, and uses a traditional single-structure stirring rack to achieve heating and mixing of materials. The hot air generated by the hot air blower diffuses unevenly in the tank, which easily forms a temperature gradient, resulting in low heat transfer efficiency. Moreover, the stirring range of the single stirring rack is limited, which cannot make the catalyst material fully contact the hot air, further weakening the overall heating effect. This not only prolongs the catalyst activation cycle, but may also affect the consistency of the activity of the activated catalyst due to insufficient heating, making it difficult to adapt to high-efficiency catalyst activation scenarios.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Firstly, this invention utilizes a dual-path heating system through the coordinated design of the heat conduction and induction mechanisms. This eliminates the need for traditional hot air blowers, significantly reducing equipment manufacturing costs and energy consumption. The annularly arranged electric heating tubes can directly envelop the activation tank body for heating, achieving rapid temperature rise and uniform conduction within the tank. Simultaneously, the heat insulation cover effectively reduces heat loss and improves heat utilization. Part of the heat generated by the electric heating tubes is transferred to the heat conduction box through the first and second heat conduction tubes, preheating the air entering the heat conduction box. The preheated hot air is then transported to the tank through the air duct and annular air guide plate by a fan. This heat recycling method allows for sufficient heat exchange between the hot air and the catalyst material inside the tank, avoiding the temperature gradient problem caused by a single heating source. This significantly improves the overall heating efficiency, shortens the catalyst activation cycle, and ensures the consistency of catalyst activity after activation.
[0016] Secondly, in this invention, the hot air guiding mechanism and the stirring mechanism are linked by a drive motor, achieving integrated control of hot air delivery and material stirring. This further enhances heating uniformity. When the drive motor is running, it not only drives the fan wheel to rotate inside the heat-conducting box through the hot air guiding mechanism, accelerating the heat circulation inside the heat-conducting box and helping the preheated hot air to smoothly enter the heat-conducting mechanism, thus improving the hot air delivery efficiency, but also drives the stirring mechanism. Through the meshing of the active toothed cone and two sets of transmission toothed cones, the transmission outer shaft and transmission inner shaft rotate in opposite directions, thereby causing the first stirring frame and the second stirring frame to stir the catalyst material in the tank in opposite directions. The bidirectional stirring design expands the stirring range, breaks the material agglomeration phenomenon, and allows the catalyst material to come into full contact with the hot air, ensuring that most of the material can be heated evenly, effectively avoiding the problem of insufficient local heating, and further improving the catalyst activation quality.

[0023] Please see Figure 1 and Figure 7The heat-conducting mechanism 9 includes an electric heating tube 91, which is fixedly connected to the outer surface of the activation tank body 1. Multiple electric heating tubes 91 are arranged in a ring structure. A heat insulation cover 92 is fixedly connected to the outer side of the multiple electric heating tubes 91 on the activation tank body 1. The heat insulation cover 92 can be a composite structure with a double-layer stainless steel shell and an inner layer filled with aluminum silicate fiber cotton. The outer layer is made of 304 stainless steel plate, which has good corrosion resistance and mechanical strength, protecting the internal heat insulation material from external environmental influences and extending its service life. The inner layer can be made of high-temperature resistant stainless steel plate, directly contacting the electric heating tubes 91 to ensure no deformation or damage under long-term high-temperature conditions. The aluminum silicate fiber cotton filling has extremely low thermal conductivity and excellent high-temperature resistance, effectively preventing heat loss from the electric heating tubes 91 to the outside, thereby improving heat utilization. A first heat-conducting tube 93 is fixedly connected to both sides of the heat insulation cover 92. A second heat-conducting tube 94 is detachably connected to one side of the first heat-conducting tube 93, and the second heat-conducting tube 94 is located away from the first heat-conducting tube.

The porous heat-insulating film 942 is made of nano-ceramic fiber material with a pore size of 10μm-50μm, allowing external air to enter while... By utilizing the material's low thermal conductivity and tortuous porous structure, the backflow of hot air inside the heat-conducting box 95 is reduced. By setting up structures such as electric heating tube 91, heat insulation cover 92, first heat-conducting tube 93, second heat-conducting tube 94, and heat-conducting box 95, the dual heating effect of direct heating of the tank and preheating of hot air can be achieved. The annular electric heating tube 91 ensures uniform heating of the tank, the heat insulation cover 92 reduces heat loss, and the porous heat insulation film 942 can prevent heat from being lost in reverse. At the same time, external air is introduced and pre-mixed to improve the efficiency of heat recycling.
[0024] Please see Figure 7 A first docking block 96 is fixedly connected to one side of the first heat pipe 93, and a second docking block 97 is fixedly connected to one side of the second heat pipe 94.

[0025] Please see Figures 3-5The heat extraction mechanism 10 includes a fan 101, which is fixedly connected to the activation tank cover 6 on one side of the heat conduction box 95. The air inlet of the fan 101 is fixedly connected to one end of the heat conduction box 95, and the connection is sealed. The output end of the fan 101 is fixedly connected to a guide pipe 102. One side of the guide pipe 102 passes through the activation tank cover 6 and extends into the interior of the activation tank body 1. An annular guide plate 103 is fixedly connected to one side of the guide pipe 102. Pipe 102 is connected to an annular air guide plate 103. The bottom end of the annular air guide plate 103 is provided with an air guide port 104, and multiple air guide ports 104 are provided. By setting up a fan 101, air guide pipe 102, annular air guide plate 103, and air guide ports 104, the preheated hot air can be evenly delivered into the tank. The annular air guide plate 103 and multiple air guide ports 104 work together to expand the coverage of hot air, avoid local accumulation of hot air, ensure that the catalyst material is in full contact with the hot air, and improve the heating uniformity.
[0026] Please see Figures 6-9 The hot air guiding mechanism 12 includes a first transmission rod 121, which is fixedly connected to the output end of the drive motor 11. A worm gear 122 is fixedly connected to the first transmission rod 121. A worm wheel 123 is meshed with the lower side of the worm gear 122. A second transmission rod 124 is fixedly connected to the middle of the worm wheel 123. The second transmission rod 124 is rotatably connected to the two heat conduction boxes 95. A fan wheel 125 is fixedly connected to both sides of the second transmission rod 124. The fan wheel 125 is rotatably connected to the inside of the heat conduction box 95 through the second transmission rod 124.

At the same time, it provides auxiliary power for the hot air to enter the fan 101, ensuring the stability and smoothness of the hot air delivery.
[0027] Please see Figures 3-5The stirring mechanism 13 includes a driving bevel gear 137, which is fixedly connected to the end of the first transmission rod 121 away from the worm gear 122. A first transmission bevel gear 131 is meshed with one side of the driving bevel gear 137, and an outer transmission shaft 132 is fixedly connected to one side of the first transmission bevel gear 131. The outer transmission shaft 132 is rotatably connected to the middle of the activation tank cover 6. A second transmission bevel gear 134 is meshed with the other side of the driving bevel gear 137, and an inner transmission shaft 135 is fixedly connected to one side of the second transmission bevel gear 134. The inner transmission shaft 135 is located inside the outer transmission shaft 132, and the two are rotatably connected. One side of shaft 132 is located inside the upper side of the activation tank body 1, and a first stirring frame 133 is fixedly connected to its outer surface. One side of the inner transmission shaft 135 is located inside the lower side of the activation tank body 1, and a second stirring frame 136 is fixedly connected to its outer surface. By setting up the active tooth cone 137, the first transmission bevel gear 131, the outer transmission shaft 132, the first stirring frame 133, the second transmission bevel gear 134, the inner transmission shaft 135, and the second stirring frame 136, the various structures cooperate to realize bidirectional reverse stirring of materials in the upper and lower areas of the tank, break up material stratification and agglomeration, expand the stirring coverage area, and make the catalyst material come into full contact with the hot air, further improving the heating uniformity and activation effect.
[0028] The working principle of this invention is as follows: Relevant parameters are preset on the control panel 3, including activation temperature, heating time, gas supply ratio, stirring speed, and hot air conveying rate. When adding materials, the sealing cap of the feeding pipe 7 on the activation tank cover 6 is opened, and the pretreated catalyst material is slowly fed into the activation tank body 1 along the feeding pipe 7. After feeding, the sealing cap is quickly closed to ensure the tank's airtightness, preventing heat loss and gas leakage during subsequent heating, and avoiding the introduction of external impurities that could affect the catalyst activation quality. After material feeding, the gas supply system and heat conduction mechanism 9 are activated to begin the preheating and gas replacement process. The operator starts the gas storage tank 4 via the control panel 3, and the proportional valve and flow meter on the gas supply pipe 5 precisely adjust the activation temperature according to the preset parameters. The required gas supply quantity and ratio are determined, and a specific gas is uniformly delivered to the activation tank body 1 through the gas supply pipe 5 until the preset gas environment is reached inside the tank. Simultaneously, the heat conduction mechanism 9 is activated, and multiple electric heating tubes 91 arranged in a ring on the outer surface of the activation tank body 1 begin to work, providing a wrapping heating effect to the activation tank body 1. This causes the temperature inside the tank to rise rapidly and be evenly conducted to all internal areas. The electric heating tubes 91 adopt a ring structure design, which, compared to a traditional single heating source, can significantly expand the heating coverage area and avoid localized excessively high or low temperatures inside the tank. The heat insulation cover 92 on the outside of the activation tank body 1 provides heat insulation, effectively preventing the heat generated by the electric heating tubes 91 from dissipating to the outside, significantly improving heat utilization and reducing energy consumption. During this process, the electric heating... Part of the heat generated by pipe 91 is transferred through the first heat-conducting pipe 93 and the second heat-conducting pipe 94 to the heat-conducting boxes 95 on both sides of the top of the activation tank cover 6, preparing for subsequent hot air preheating. External air is introduced through the air pipe 941 on one side of the second heat-conducting pipe 94. The porous heat-insulating film 942 inside the air pipe 941 prevents heat from being lost back to the outside from the heat-conducting box 95, and simultaneously performs preliminary filtration and pretreatment of the introduced air, ensuring that the air entering the heat-conducting box 95 is clean and can quickly absorb heat, achieving heat recycling. The drive motor 11 is started, linking the hot air guiding mechanism 12 and the stirring mechanism 13. After the drive motor 11 starts, it synchronously drives the hot air guiding mechanism 12 and the stirring mechanism 13 to work, realizing integrated control of hot air delivery and material stirring. The output of the drive motor 11 drives the first transmission rod 121 to rotate. The worm gear 122 on the first transmission rod 121 meshes with the worm wheel 123, driving the second transmission rod 124 to rotate. This causes the fan wheels 125 on both sides of the second transmission rod 124 to rotate at high speed inside the heat conduction box 95. The rotation of the fan wheels 125 accelerates the mixing and circulation of heat and air inside the heat conduction box 95, allowing the introduced air to fully absorb the heat transferred by the electric heating tube 91, quickly raising the temperature to form hot air. At the same time, it provides auxiliary power for the hot air to enter the heat-inducing mechanism 10, ensuring the stability of the hot air delivery and avoiding heat accumulation or poor hot air delivery inside the heat conduction box 95. Subsequently, the fan 101 of the heat-inducing mechanism 10 starts, drawing the preheated hot air inside the heat conduction box 95 into the air inlet.After being pressurized by the blower 101, the hot air is delivered to the interior of the activation tank body 1 through the air duct 102. The annular air guide plate 103, which is connected by the two air guide plates 102, plays a role in uniformly distributing the air. Multiple air guide ports 104 opened at the bottom of the annular air guide plate 103 evenly disperse the hot air into the tank, expanding the coverage area of the hot air. At the same time, the drive motor 11 drives the active toothed bevel 137 at the end to rotate through the first transmission rod 121. The active toothed bevel 137 meshes with the first transmission bevel gear 131 and the second transmission bevel gear 134 on both sides. Since the meshing direction is opposite, it drives the transmission outer shaft 132 and the transmission inner shaft 135 to rotate in opposite directions. The outer drive shaft 132 is located inside the upper part of the activation tank body 1. The first stirring frame 133 on its outer surface rotates with the outer drive shaft 132 to stir the catalyst material in the upper part of the tank. The inner drive shaft 135 is located inside the outer drive shaft 132. The second stirring frame 136 on its outer surface rotates in the opposite direction with the inner drive shaft 135 to stir the catalyst material in the lower part of the tank. Compared with the traditional single stirring frame, the bidirectional reverse stirring design not only expands the stirring coverage area, but also effectively breaks up the material stratification and agglomeration, so that the catalyst material in the upper and lower parts of the tank is fully mixed, which facilitates contact with heat. After the catalyst is activated, the electric heating tube 91 and the drive motor 11 are turned off, and the heating, hot air conveying and stirring operations are stopped, so that the temperature inside the tank drops to room temperature, ensuring the unloading process. To ensure the safety of the process, after cooling is complete, the solenoid valve on the discharge pipe 8 is opened via the control console 3, and the activated catalyst is automatically discharged through the discharge pipe 8 without manual opening of the cover, thus improving operational efficiency. This technical solution utilizes a dual-path heating system constructed collaboratively by the heat conduction mechanism 9 and the heat extraction mechanism 10, significantly reducing equipment manufacturing costs and energy consumption. The combination of the wrapping heating of the annular electric heating tube 91 and hot air preheating, along with the insulation effect of the heat insulation cover 92 and the porous heat insulation film 942, achieves efficient utilization and circulation of heat, avoiding the temperature gradient problem caused by a single heating source, significantly improving heating efficiency, shortening the catalyst activation cycle, and ensuring the consistency of catalyst activity after activation. This solution is suitable for the needs of chemical, environmental protection, and energy fields for efficient catalyst activation.
