摘要

Electrostatic precipitators (Fig. 1) are used for dust removal and their efficiency influences the environment. However, the effectiveness of these devices depends on many factors [1-10]. One of them is the efficiency of a periodic cleaning of the collecting electrodes (Fig. 1, pos. nZE) - the dust is removed by inducing vibrations at accelerations. These vibrations are caused by axial impact of a beater (Fig. 2, pos. US) on a dust-removal bar. In the course of impact and after its finish the impact stresses are produced in both - shaking down and collecting electrodes - systems. These processes have been the subject of numerous works, e.g. they are dealt with in [11, 12, 13] and many others. The results of calculations obtained by means of the method described in [14] are compared with those obtained from measurements. The paper briefly characterizes the measurement equipment (Tab. 1) used and the manner of measurements (Fig. 2). The author also presents his own methodology (Section 3), enabling applying it for validation of numerical models (Section 4) of one of the collecting electrode sections (Fig. 1, pos. ZEP). In conclusion it can be stated that the preliminary analysis carried out on such a systematic collection of data shows the directions for further procedures on validating numerical models for dynamic simulations.
