WIPO Patent Application WO/2023/105882

A1

[Problem] To provide: a method for diagnosing deterioration of a metal filter which makes it possible to accurately diagnose metal filter deterioration, regardless of whether a dust collector is operating or stopped; and a deterioration diagnosis system. [Solution] Provided is a method for diagnosing deterioration of a metal filter 6 according to the present invention, said method being characterized in that an electrical property value (electrical resistance value) of the metal filter 6 is detected, and the deterioration of the metal filter 6 is diagnosed on the basis of the detected electrical property value. Further provided is a deterioration diagnosis system for a metal filter 6 according to the present invention which is equipped with: a power supply device 21 for conducting electricity to the metal filter 6; a resistance measurement device 22 for detecting an electrical property value (electrical resistance value) of the metal filter 6; a transmitter 30 for transmitting the electrical property value (electrical resistance value) of the metal filter 6 as a signal; a receiver 40 for receiving the electrical property value signal (electrical resistance value signal) transmitted by said transmitter 30; and a deterioration diagnosis device 60 for diagnosing deterioration of the metal filter 6 on the basis of the electrical property value signal received by the receiver 40.
