A method and system for extinguishing and cooling treatment of high-temperature activated carbon in the unloading section after analysis

Abstract

After analyzing the method of extinguishing and cooling the high-temperature activated carbon in the discharge section, the method sets a thermal imager in the discharge conduit to take real-time pictures of the activated carbon flowing through the discharge conduit to obtain a thermal imaging image. Then, according to the thermal imaging image analysis, it is judged whether the activated carbon flowing through the discharge conduit has a high temperature point. If there is a high temperature point, the corresponding high temperature activated carbon is extinguished and cooled by spraying oxygen barrier fire extinguishing gas or spraying water mist in the silo. The invention detects spontaneously ignited high-temperature activated carbon in the unloading link of the activated carbon flue gas purification device, and can extinguish and cool it, solves the problem that high-temperature activated carbon particles are difficult to be fully detected and disposed of, and improves system safety.

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 extinguishing and cooling high-temperature activated carbon in a discharge section after analysis, 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 wor...
