Method and system for high-temperature detection of activated carbon and cooling and extinguishing of spontaneous combustion activated carbon

Abstract

A method for high-temperature detection of activated carbon and cooling and extinguishing of spontaneous combustion activated carbon comprises the following steps: 1) a thermal imager (1) shoots a material entering an imaging area (3) on a vibrating screen (2) in real time to obtain a thermal imaging image; 2) analyzing and judging whether the material entering the imaging area (3) has a high-temperature point or not according to the thermal imaging image; 2a) if it is judged that the thermal imaging image does not have the high-temperature point, repeating the step (1); 2b) if the thermal imaging image has the high-temperature point, recording the finding position of the material at the high-temperature point in the imaging area (3) on the vibrating screen (2); and 3) when the materials at the high-temperature points move to a conveyor (5), performing water spraying cooling treatment on the corresponding high-temperature materials. Spontaneous combustion high-temperature activated carbon is detected in the screening link of the activated carbon flue gas purification device and can be positioned and treated, the problem that high-temperature activated carbon particles are difficult to comprehensively detect and treat is solved, 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 high-temperature detection of activated carbon and cooling and extinguishing of spontaneously combusted activated carbon, belonging 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 achiev...
