Abstract

The invention relates to a self-adjusting system and method for PM 2.5 flue gas flow fields. The self-adjusting system is characterized by comprising flue gas detection devices, an online monitoring device and an automatic-control adjusting device; the flue gas detection devices are distributed at all detection points of a flue gas pipeline and a dust removal box and fixed to the inner wall of the flue gas pipeline and the inner wall of the dust removal box through supporting legs, detection heads of the flue gas detection devices are exposed to the flue gas pipeline by different heights for sampling, and the flue gas detection devices are connected with the online monitoring device and transmit detection and analysis results to a center processing unit of the online monitoring device; the center processing unit controls flow guide plates in the flue gas pipeline to turn and an air pressure pump in the dust removal box to be turned on or off through a real-time synchronous control system of the automatic-control adjusting device according to the distribution condition of the flue gas flow fields. The self-adjusting system and method can detect PM2.5 in a distributed mode or on line, and the flow fields in the flue gas pipeline and the dust removal box can be controlled intelligently.

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...
