Abstract
Description
Technical Field
[0001] This application relates to the field of chute technology, and more specifically, to an activated carbon feeding chute. Background Technology
[0002] Activated carbon, with its well-developed microporous structure and abundant surface area, has excellent adsorption properties and is widely used in desulfurization and denitrification devices. It can effectively adsorb harmful substances such as sulfur dioxide and nitrogen oxides in flue gas, thereby purifying the flue gas and reducing air pollution.
[0003] The recycling and reuse of activated carbon not only helps conserve resources but also reduces waste generation and environmental pollution. Through recycling and reuse, the exploitation of primary resources can be reduced, energy consumption and carbon emissions can be decreased, thus achieving sustainable development. In existing technologies, the discharge and dust removal of activated carbon from the purification tower of desulfurization and denitrification devices must be carried out in separate steps. This method has the following drawbacks: 1. Dust released during activated carbon discharge poses a significant health hazard. 2. The adsorption capacity of activated carbon decreases. 3. Performing material discharge and dust removal in separate steps wastes manpower and resources. Utility Model Content
