Abstract

The invention provides a method for conducting secondary fire extinguishing and cooling treatment on high-temperature activated carbon. The method comprises the steps that firstly, when it is detected that materials entering a vibrating screen (1) have high-temperature points, primary fire extinguishing and cooling treatment is conducted on the high-temperature materials through a first spontaneous combustion activated carbon extinguishing and cooling device arranged on a discharging pipe (3) between the vibrating screen (1) and a conveyor (2); and secondly, when the materials at the high-temperature point move into a discharge hopper (4) connected with a discharge port of the conveyor (2), secondary fire extinguishing and cooling treatment is conducted on the high-temperature materials through a second spontaneous combustion activated carbon extinguishing and cooling device arranged at the upper part of the discharge hopper (4). High-temperature activated carbon at the tail of the vibrating screen can be treated in time through primary treatment of the discharging pipe, the high-temperature activated carbon can be further extinguished and cooled through secondary treatment of the discharging hopper, and therefore the extinguishment and cooling effects of high-temperature materials are ensured, and the safety of the system is improved.

Description

technical field [0001] The invention relates to the detection and treatment of high-temperature activated carbon particles in an activated carbon flue gas purification device, in particular to a method and system for secondary fire-extinguishing and cooling treatment of high-temperature activated carbon, and belongs to the technical field of activated carbon flue gas purification. Background technique [0002] The amount of flue gas produced in the sintering process accounts for about 70% of the entire iron and steel process, and the main pollutants in the sintering flue gas are dust, SO 2 , NO X ; In addition, there are a small amount of VOCs, dioxins, heavy metals, etc.; they need to be purified before they can be discharged. At present, the technology of activated carbon desulfurization and denitrification device for treating sintering flue gas has been mature, and it has been popularized and used in China, and good results have been achieved. [0003] The working schem...
