Abstract

Abstract Translated from German Die Erfindung bezieht sich auf ein Verfahren zum Betrieb eines Elektrofilters (4) mit Gleichspannung (Ug) und überlagerten Impulsen (UP) oder überlagerter Wechselspannung. Auf iterativem Wege werden die einzelnen Parameter, wie Amplituden, Pulsfolgefrequenz, Pulsbreite usw. fortlaufend derart verändert, daß die Summe (E1 + E2) aus Puls- und Gleichspannungsleistung einem Minimum zustrebt. Hierzu wird ein Rechner (5) benutzt, der aus der Staubbeladung und den aufgenommenen el. Energien des Filters die Steuerbefehle für Gleich- und Impulsspannungsquelle (2, 3) berechnet. The invention relates to a method for operating an electrostatic filter (4) with DC voltage (Ug) and superimposed pulses (UP) or superimposed AC voltage. The individual parameters, such as amplitudes, pulse repetition frequency, pulse width, etc., are continuously changed in an iterative way in such a way that the sum (E1 + E2) of pulse and DC voltage power tends to a minimum. For this purpose, a computer (5) is used, which calculates the control commands for direct and pulse voltage sources (2, 3) from the dust loading and the absorbed electrical energies of the filter.
