Abstract

PURPOSE: To contrive to save energy of the dust collecting apparatus by pulsatively changing the value of a control signal for making dust concn. constant as a constant value in an appropriate cycle to intermittently repeat charging and the stopping of charging.
CONSTITUTION: A pulse generator 5 generating pulse as a signal to a gate 4 has control function and, when an output signal D of a dust densitometer 6 becomes small and dust concn. becomes low, a power supply time T1 is reduced or a power stopping time T2 is increased and, when said signal D becomes large on the contrary, the power supply time T1 is increased or the power stopping time T2 is reduced. By this mechanism, while the dust concn. is held to a desired value, power consumption becomes zero during the power suspending time T2.
