Abstract

The invention belongs to the technical field of chemical equipment monitoring and control, and particularly relates to a method for detecting the suspension effect of particles in a stirring reactor, which comprises the following steps: preparing fluorescent beads with different sizes; liquid is injected into the stirring reactor, all the fluorescent beads are put into the liquid, and the liquid is stirred through a stirrer; the stirring reactor is irradiated by an ultraviolet lamp, so that the fluorescent beads in the stirring reactor emit fluorescence; a real-time monitoring module is adopted to collect images of the small fluorescent balls in the stirring reactor; analyzing the fluorescent ball image to obtain a motion track, an instantaneous rate and a direction of the fluorescent ball; obtaining the suspension effect of the particles in the liquid according to the motion trail, the instantaneous rate and the direction of the small fluorescent balls; through the high-speed camera and the intelligent image processing module, the particle suspension state can be captured in real time, and the detection efficiency is remarkably improved.
