AI Technical Summary
In existing online monitoring devices for particulate matter in high-temperature flue gas, particulate matter easily accumulates on the surface of the photosensitive sensor, affecting the detection accuracy.
A monitoring device including an electrostatic monitor, a sliding plate, and a scraper is designed. The electrostatic induction module monitors the concentration of particulate matter, the sliding plate removes particulate matter from the surface of the electrostatic monitor, and the scraper removes particulate matter from the inner wall of the monitoring frame. The rotation speed of the scraper is reduced by combining a fixed plate and a driven plate.
It effectively removes particulate matter from the surface of electrostatic monitors, maintains monitoring accuracy, reduces maintenance costs, and extends equipment life.
