Recognition device for sulfur-containing substances in fire comburent

The invention discloses a recognition device for sulfur-containing substances in fire comburent, and the device comprises: a spectrum collection device which is used for collecting a spectrum curve of fire flames; a sulfur-containing substance combustion spectrum database storing typical sulfur-containing substance combustion spectrum curves; and a data processing device which is used for carrying out normalization processing on the spectrum curve acquired by the spectrum acquisition device relative to the stored spectrum curve, and calculating the similarity between the acquired spectrum curve and the stored spectrum curve so as to identify the sulfur-containing substances in the comburent. The invention further discloses a method for identifying the sulfur-containing substances in the fire comburent. Aiming at the characteristics of sulfur-containing chemical fire accidents, based on a flame radiation spectrum detection means, whether the field fire comburent is a sulfur-containing substance or not can be f
