Abstract

The invention discloses a method for secondary detection and secondary treatment of high-temperature activated carbon, which comprises the steps of 1) when a material entering a vibrating screen (1) from a discharge port of a desorption tower is detected to have a high-temperature point, carrying out primary fire extinguishing and cooling treatment on thehigh-temperature material through a first spontaneous combustion activated carbon extinguishing and cooling device arranged on a discharging pipe (3) between the vibrating screen (1) and the conveyor (2); and (2) when the material at the high-temperature point moves into a stock bin (4) connected with a discharge port of the conveyor (2), carrying out secondary fire extinguishing and cooling treatment on the high-temperature material through a second spontaneous combustion activated carbon extinguishing and cooling device arranged at the top of the stock bin (4). The high-temperature activated carbon at the tail of the vibrating screen can be treated in time through primary treatment of the discharging pipe, and the high-temperature activated carbon can be further extinguished and cooled through secondary treatment of the stock bin, so that the extinguishment and cooling effects of the high-temperature material 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 detection and secondary 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 schematic di...
