Abstract
In the studies related to simulation of vibrations in collecting electrodes of dry electrostatic precipitators, it is necessary to correctly determine the course of impact force of a beater on an anvil beam to which the plates with deposited particulate matter are attached. The courses of these forces have a direct impact on the effectiveness of rapping particulate matter, and therefore on accelerations causing the detachment of dust particles. The paper presents a procedure, which allows for an approximate determination of the course of impact force, based on the results of vibration measurements and computer simulation, in which a self-developed model of the system was used. The analysis covered repeated series of acceleration measurements at several tens points of the system of collecting electrodes. Acceleration measurements were performed using IPC 356A02 triaxial sensors. A computer model, based on the rigid finite element method (RFEM) allows for the determination of a course of accelerations for a strictly specific course of impact force. Comparing the results (of acceleration) obtained by measurements and calculations, a correct course of the impact force was found. Knowing the correct course of the impact force, it is possible, using only computer simulations, to conduct studies of the influence of geometrical and structural parameters of the system on the effectiveness of rapping particulate matter.
