Abstract

An on-line monitoring device and method for PM2.5 industrial flue gas, comprising a detection head, an integrated sensor, a layered isolation room, a PM2.5 detection unit, a central processing unit, a guide track, a GPRS communication module and an external display operation screen, It is supported by the guide track and walks inside the flue gas duct and dust removal box. The GPRS communication module can measure its coordinate point by positioning. The detector head is exposed to the flue gas channel at different heights for sampling, and the detector head is detected by the integrated sensor. The initially detected flue gas temperature, humidity, flow direction, flow rate, air pressure and chemical composition, the layered isolation chamber is divided into the first layered isolation chamber and the second layered isolation chamber by the PM2.5 cutter, which is divided by the PM2.5 detection unit Detect various physical and chemical characterizations of PM2.5 entering the second layered isolation room, record, analyze, process, store or draw images from the detected values ​​by the central processor, and then transmit to the external display operation screen for continuity Monitoring and system-wide instant operation.

Description

technical field [0001] The invention relates to an on-line monitoring device and method for PM2.5 industrial flue gas, in particular to the purification treatment of high-temperature flue gas from metallurgical furnaces in industries such as iron and steel, and belongs to the technical field of PM2.5 capture. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 μm in the atmosphere. It has the characteristics of small particle size and large specific surface area. It is easy to absorb toxic substances and has strong penetrating power. It can reach the bronchiole wall and affect the health of the respiratory system. , directly endanger people's health. In my country, in some important industrial cities, PM2.5 from the steel industry exceeds 30%, which has aroused people's great concern. [0003] In the PM2.5 cleaning and dust removal process, the uniformity of the flue flow field distribution directly affects the efficien...
