    摘要： A control system for a dust collecting apparatus including an upright housing (10) arranged above a dust storage bin (13), a ceramic filter assembly (20) disposed within the housing to collect dust particles from exhaust gases supplied into a bottom portion of the housing located at an upstream thereof, and a reverse washing mechanism (30) mounted on the housing at a downstream of the filter assembly to cause the collected dust particles to fall into the dust storage bin (13) from the filter assembly when it is activated, wherein temperature (T1) and pressure (P1) of the exhaust gases supplied into the housing at the upstream of the filter assembly, temperature (T2) and pressure (P2) of purified gases discharged from the filter assembly into an upper portion of the housing located at the downstream of the filter assembly and a flow quantity (Q1) of the purified gases discharged from the housing at the downstream of the reverse washing mechanism are detected to calculate an average temperature [T = f(T1, T2)], a flow quantity [(Q = f(Q1, T)], viscosity [(η = f(T)] and
    a pressure loss coefficient [K = f(ΔP, Q, η)] of the exhaust gases passing through the filter assembly, and wherein the reverse washing mechanism (30) is activated under control of an electronic controller (41) when the calculated pressure loss coefficient (K) becomes more than a predetermined value (K0) and is deactivated when the calculated pressure loss coefficient becomes less than the predetermined value (K0).
