Description

Technical Field

[0001] The invention belongs to the technical field of energy conservation and environmental protection, and specifically refers to an activated carbon regeneration device for waste gas treatment. Background Art

[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated under air-tight conditions to reduce non-carbon components (this process is called carbonization), and then react with gas, the surface is eroded, and a well-developed microporous structure is produced. The porous structural characteristics and non-polar properties of activated carbon determine its extremely strong adsorption capacity, which enables it to adsorb all pollutants present in exhaust gas, such as volatile organic compounds in organic exhaust gas, certain heavy metal ions in inorganic exhaust gas, etc. It is widely used in life and production. Among them, granular activated carbon has been widely used in exhaust gas treatment due to its rich pore structure, large specific surface area, strong adsorption capacity, high mechanical strength, and easy filling. However, the principle of activated carbon adsorption determines that it has a service life. After a period of use, as pollutants accumulate, the adsorption capacity will weaken or even completely lose its adsorption capacity. At this time, the activated carbon is called saturated carbon. Therefore, it is necessary to remove the attached pollutants from the saturated activated carbon through technical means to achieve activated carbon regeneration. This process is called desorption. Common activated carbon regeneration methods are High temperature regeneration method, chemical regeneration method, biological regeneration method, steam regeneration method and microwave regeneration method, etc. The principle of chemical regeneration method is to remove pollutants attached to activated carbon by washing activated carbon with chemical solutions such as acidic washing solution. It has the advantages of simple operation and can select corresponding chemical solutions for targeted desorption according to the characteristics of pollutants in use. The washing desorption method is particularly suitable for the regeneration of granular activated carbon. The current activated carbon chemical regeneration device can only perform simple washing on activated carbon. However, granular activated carbon will cause damage to activated carbon during disassembly, transportation, filling, etc., and produce small particles smaller than the standard size, which makes it not meet the requirements of the original use scenario and reduces the adsorption performance. Even if the activated carbon is screened before or after regeneration, it cannot avoid damage to the activated carbon caused by the operation. At the same time, activated carbon particles of different sizes need to be soaked and washed in the solution for different times. If the smaller particles of activated carbon are washed in the solution for too long, it will damage the activated carbon and destroy the microporous structure of the activated carbon, thereby reducing its adsorption capacity and reducing the product quality. Therefore, a better performance activated carbon regeneration device is needed. Summary of the invention

At the same time, when it is necessary to classify the small-particle activated carbon more finely, choose to install the inner cylinder 5 with filter holes 502 of different sizes. Since the smaller the particles of activated carbon, the shorter the washing time required, the filter hole 502 is operated from small to large, starting from the smallest size, and starting the driving rod 206 above the current collecting mechanism 3. The second drive motor 205 is started, and the other second drive motors 205 do not work. The small-sized activated carbon particles of the current size are collected. After the collection of the activated carbon particles of the current size is completed and the washing time of the activated carbon of this size is reached, the current collecting mechanism 3 is taken out and not put back, and then the second drive motor 205 above the inner tube 5 with the next-sized filter hole 502 is started. The above operation is repeated to collect and take out until the collection and washing of all the small-sized activated carbon particles are completed. The second drive motor 205 is turned off, and the drive motor 1 202 continues to drive the drive rod 206 to rotate to stir the activated carbon of the standard size until it is taken out after regeneration is completed.
