Title: Method and device for intermittent external electrostatic charging of air filter
Inventor: SHINAGAWA TAKEHISA
IPC: B03C3/66
Filed: 1982-05-01
Abstract: PURPOSE:To maintain the capturing efficiency of an air filter having low capturing efficiency at a high rate for a long period of time, by setting the upper limit value and lower limit value of the concn. of suspended dust on the upper stream or down stream side of the filter and halting or starting external electrostatic charging intermittently. CONSTITUTION:The upper limit value and lower limit value of the concn. of suspended dust on the upperstream or downstream side of an air filter having relatively low capturing efficiency are set in the stage of using said filter. A sensor 5 is provided in the suitable position on the upperstream or downstream side of the air filter to measure the concn. of the suspended dust. The electric signal outputted from the sensor 5 is converted to a digital signal with an A/D converter 6 so as to provide a read value. The read value is processed in a microcomputer 7, and if the value is higher than the upper limit set value for the concn. of the suspended dust, the external electrostaic discharging of an intermittent external electrostatic charging device is turned on and when the value decreases down to the lower limit set value or below, said discharge is turned off. The service life of the air filter is thus extended and the electric power consumption thereof is reduced.
