Abstract: A system for removing dust from exhaust gas, comprising a dust removing system inlet, a dust removing system outlet, and an electric field apparatus (1021). The electric field apparatus (1021) comprises an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode (10212) and a dust-removing electric field anode (10211). The dust-removing electric field cathode (10212) and the dust-removing electric field anode (10211) are used to generate an ionizing electric field for dust removal. When a certain amount of dust has accumulated on the electric field apparatus, the electric field apparatus performs a black carbon removal process, thereby avoiding a reduced electrode gap resulting from an increased thickness of black carbon.
