Abstract

A PM2.5 flue gas flow field self-regulating system and method thereof, characterized in that it includes a flue gas detection device, an online monitoring device and a self-control adjustment device, and the flue gas detection device is distributed in each of the flue gas pipeline and the dust removal box The detection point is fixed on the inner wall of the flue gas pipeline and the dust removal box through the feet. The detection head of the flue gas detection device is exposed to the flue gas channel at different heights for sampling. The flue gas detection device is connected with the online monitoring device to transmit the detection and analysis results. Based on the central processing unit of the online monitoring device, the central processing unit controls the start-up of the flue gas pipe and the deflector inside the dust removal box and the air pressure pump through the multi-channel real-time synchronous control system of the self-control adjustment device according to the distribution of the flue gas flow field. Close and turn. The invention can realize the distributed detection and online monitoring of PM2.5, and can realize the intelligent control of the flow field inside the flue gas pipeline and the dust removal box.

Description

technical field [0001] The invention relates to a PM2.5 flue gas flow field self-regulating system and method thereof, 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...
