High-temperature detection method and high-temperature detection system for activated carbon flue gas purification device

Abstract

The invention discloses a high-temperature detection method and high-temperature detection system for an activated carbon flue gas purification device. The high-temperature detection method for an activated carbon flue gas purification device comprises the following steps: 1), a thermal imager (1) shoots a material entering a first imaging area (301) on a vibrating screen (2) in real time to obtain a primary thermal imaging image; and 2), analysis is performed according to the primary thermal imaging image and whether the material entering the first imaging area (301) has a high-temperature point or not is determined; if so, the thermal imager (1) tracks and shoots a secondary thermal imaging image, entering a second imaging area (302) on the vibrating screen (2), of the material at a suspected high-temperature point, and whether the suspected high-temperature point is a high-temperature point or not is judged; and if the suspected high-temperature point is determined to be a high-temperature point, recording the finding position of the material at the high-temperature point in a second imaging area (302) on the vibrating screen (2) is recorded, and an alarm is made. The high-temperature activated carbon particles are detected by adopting the high-temperature activated carbon particle detection device, the detection accuracy can be improved, meanwhile, the problem that comprehensive detection is difficult is solved, and the safety of a system is improved.

Description

Technical field[0001]The present invention relates to the detection of high temperature activated carbon particles in the active carbon flue gas purifying apparatus, and specifically, a high temperature detection method of activated carbon flue gas purification means and its detection system belongs to the field of activated carbon smotting.Background technique[0002]The amount of flue gas generated by the sintering process accounts for about 70% in the steel full process, and the main pollutant components in the sintered flue gas are dust, so2NOXThere is also a small amount of VOCS, two dioxin, heavy metals, etc .; after purification is required. At present, the technology of activated carbon dethyldulfur debride debris deinterletter is mature, and it has been promoted in China, and has achieved good results.[0003]The prior art method of working in the active carbon deinterlean deinterletter is likefigure 1 As shown: the original flue gas generated by the sintering process (the main...
