Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon modification equipment, and in particular to an aerosol fluidized activated carbon modification equipment. Background Technology

[0002] Existing activated carbon modification methods mainly employ impregnation modification technology, specifically involving spraying a modifying solution onto the activated carbon surface or impregnating the activated carbon with a modifying solution. However, existing activated carbon modification methods cannot achieve uniform loading, resulting in inconsistent product quality. The main reason is that current spraying or impregnation modification solutions cannot penetrate deep into the pores of the activated carbon for modification, or the modifier is excessively loaded onto the pores, even causing blockage, leading to poor adsorption performance.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0019] This utility model provides an aerosol fluidized activated carbon modification device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0021] Please see Figure 1 This utility model provides an aerosol fluidized activated carbon modification device, including an aerosol generator 1, an activated carbon modification tank 2, a Venturi chamber 3, and an air inlet pipe 4. An induced draft fan 5 is installed on the air inlet pipe 4. A gas inlet is provided at the bottom of the activated carbon modification tank 2. The Venturi chamber 3 is located below the activated carbon modification tank 2. A gas outlet is provided at the top of the Venturi chamber 3, an air inlet is provided at its bottom, and an aerosol inlet is provided on its side. The gas outlet of the Venturi chamber 3 is connected to the gas inlet of the activated carbon modification tank 2. The air inlet is connected to the air inlet pipe 4. The aerosol inlet is connected to the aerosol generator 1.

[0022] Specifically, a Venturi tube is installed inside the Venturi chamber 3. An activated carbon inlet is provided on the activated carbon modification tank 2. This invention is suitable for the modification of small-particle activated carbon (particle size 1.5mm~10mm). The air generated by the blower 5 first passes through the Venturi chamber 3, mixes with the aerosol through the Venturi effect, and then enters the activated carbon modification tank 2, contacting the activated carbon particles inside. Due to the small mass of the activated carbon particles, they tumble under the action of the airflow, thus forming a fluidized state. In the fluidized state, the surface of the activated carbon particles can be uniformly contacted with the aerosol. The aerosol particles have a particle size ≤3 micrometers, allowing them to penetrate deep into the pores of the activated carbon particles for modification, resulting in thorough modification without clogging.

[0023] Please see Figure 1 In a preferred embodiment, the activated carbon modification tank 2 is provided with a support mesh 21 inside, which is used to hold the activated carbon. Specifically, the pore size of the support mesh 21 is smaller than the particle size of the activated carbon particles.

[0024] Please see Figure 2 In a preferred embodiment, the aerosol fluidized activated carbon modification equipment further includes a vacuum device 6, which is connected to the activated carbon modification tank 2. In this embodiment, after the activated carbon is filled, the activated carbon modification tank 2 is first evacuated before the induced draft fan 5 and the aerosol generator 1 are turned on. This approach removes air from the activated carbon beforehand, allowing it to better adsorb aerosols and undergo modification.

[0025] Please see Figure 2 In a preferred embodiment, the activated carbon modification tank 2 is provided with a first exhaust pipe 71 at its top. The top of the first exhaust pipe 71 is connected to a second exhaust pipe 73 or a circulation pipe 74 via a first tee pipe 72. An exhaust valve 731 is provided on the second exhaust pipe 73. A first circulation valve 741 is provided at the air inlet end of the circulation pipe 74. The air outlet end of the circulation pipe 74 is connected to the air inlet end of the induced draft fan 5. In this embodiment, during modification, the exhaust valve 731 is closed, the first circulation valve 741 is opened, and the aerosol gas is discharged from the first exhaust pipe 71 and enters the circulation pipe 74. Then, it passes through the induced draft fan 5 and re-enters the air inlet pipe 4, finally circulating back into the activated carbon modification tank 2, allowing the aerosol to fully contact the activated carbon. After modification, the first circulation valve 741 is closed, the exhaust valve 731 is opened, the aerosol generator 1 is turned off, the induced draft fan 5 continues to run, and the gas is discharged from the second exhaust pipe 73.

[0026] Please see Figure 2In a preferred embodiment, the air inlet of the induced draft fan 5 is connected to a first induced draft duct 75, which is connected to a second induced draft duct 77 or a circulation duct 74 via a second tee pipe 76. A second circulation valve 742 is installed at the outlet of the circulation duct 74. An inlet valve 771 is installed on the second induced draft duct 77. During aerosol gas circulation, both the second circulation valve 742 and the inlet valve 771 are open, although the opening of the inlet valve 771 can be reduced to allow a small amount of external air to be drawn into the second induced draft duct 77, supplementing the circulating gas. When circulation is not in progress, the second circulation valve 742 is closed to prevent gas from entering the circulation duct 74.

[0027] Please see Figure 2 In a preferred embodiment, a drying device 8 is installed on the second exhaust duct 77. In this embodiment, after the activated carbon modification is completed, the drying device 8 can be turned on to generate hot, dry air to dry the modified activated carbon. Specifically, during drying, the aerosol generator 1 is turned off. The air passes through the drying device 8 to form hot, dry air, which enters the activated carbon modification tank 2 and carries away the moisture from the modified activated carbon. Because aerosol modification requires less water, the modified activated carbon can be dried quickly in a short time, resulting in lower energy consumption and less loss of effective components within the modified activated carbon.

[0028] Please see Figure 2 In a preferred embodiment, a filter screen 31 is provided inside the venturi chamber 3. The filter screen 31 is used to filter impurity particles in the air and prevent them from entering the activated carbon and clogging the pores.

[0029] Please see Figure 2 In a preferred embodiment, the bottom of the activated carbon modification tank 2 is an inverted cone shape.

[0030] Please see Figure 2 In a preferred embodiment, a one-way valve 9 is provided at the connection between the aerosol generator 1 and the aerosol inlet. The one-way valve 9 is used to allow the aerosol to enter the Venturi chamber 3 in one direction, preventing gas from entering the aerosol generator 1 in reverse during exhaust or drying processes.

[0031] In summary, this invention uses an aerosol generator 1 to form an aerosol from the modified liquid, which is then introduced into the activated carbon modification tank 2 to modify the activated carbon. At the same time, the activated carbon particles in the activated carbon modification tank 2 are tumbled and fluidized by the action of wind, which effectively improves the modification quality of the activated carbon and the utilization rate of the modified liquid.
