Description

Technical Field

[0001] This utility model relates to the field of activated carbon wear testing technology, and in particular, to a test cylinder for the wear resistance strength of desulfurization and denitrification activated carbon. Background Technology

[0002] Non-power industries, such as steel, coking, and cement, share common characteristics in their flue gas: high humidity, high dust, high SO2, and high NOx. In addition, different industries' flue gas also contains trace amounts of VOCs, dioxins, heavy metals, and other components. Achieving synergistic, efficient, economical, and environmentally friendly treatment is a fundamental requirement for industrial flue gas purification. Activated carbon flue gas purification technology is an advanced process that synergistically removes multiple pollutants, has low operating costs, is highly water-saving, enriches and utilizes SO2 resources, and catalytically reduces NOx. The basic principle of desulfurization is that activated carbon adsorbs SO2 from the flue gas. The activated carbon that adsorbs SO2 then thermally desorbs SO2 and produces valuable chemical products such as sulfuric acid. The regenerated activated carbon restores its adsorption performance and is returned to the system for continued use. The basic principle of denitrification is that activated carbon acts as a low-temperature denitrification catalyst, where NOx reacts with injected NH3 under catalytic action to transform into non-toxic N2. The basic principle of dust removal is that when flue gas passes through an activated carbon bed, dust is intercepted or adsorbed and removed on the activated carbon surface.

[0003] Common activated carbon flue gas purification technology process flow is as follows: Figure 1 As shown, fresh activated carbon is added to the adsorption tower from the top and moves vertically downwards at a certain speed under the action of gravity. Meanwhile, the original flue gas flows horizontally through the activated carbon adsorption tower perpendicular to the flow direction of the activated carbon. Gaseous components such as SO2 and NOx in the flue gas are adsorbed or catalytically converted by the activated carbon, while dust in the flue gas is adsorbed on the surface of the activated carbon or intercepted by collision. At the same time, when the flue gas flows through the activated carbon bed, it will have a scouring effect on the activated carbon. The flue gas will carry the carbon powder on the surface of the activated carbon or the carbon powder generated by the friction between the activated carbon particles out of the system, which will become an important part of the particulate matter in the flue gas discharged from the activated carbon flue gas purification system.

[0004] In existing technologies, adsorption towers typically have a front, middle, and rear chamber structure. The front chamber has the thinnest bed and the fastest-moving activated carbon, ensuring rapid discharge of the activated carbon after adsorbing high concentrations of SO2 in the flue gas, and promptly removing the heat generated during the adsorption process from the system. The middle chamber's activated carbon moves more slowly than the front chamber, used for further removal of remaining SO2 in the flue gas. The rear chamber's activated carbon moves the slowest, used for deep SO2 removal from the flue gas, while simultaneously intercepting dust in the flue gas passing through the front and middle chambers, preventing excessive dust levels at the adsorption tower outlet. The adsorption tower's front, middle, and rear chambers, along with its special bed thickness design, maximizes activated carbon utilization efficiency, reduces ineffective activated carbon wear, and avoids the risk of excessive dust emissions.

[0005] Activated carbon wear into carbon powder is the main form of activated carbon consumption, and the carbon powder carried out by flue gas is an important reason for excessive particulate matter. Therefore, understanding the wear characteristics of activated carbon is an important basis for guiding production units to improve the wear resistance of materials in a targeted manner and guiding application units to reasonably adjust environmental protection processes, thereby improving economic efficiency, avoiding excessive carbon powder concentration, and improving environmental protection standards. Therefore, it is necessary to propose a test cylinder for the wear resistance strength of desulfurization and denitrification activated carbon. Utility Model Content
