Patent ID: 6953555

Claim:
A diesel particulate removing apparatus comprising: a plurality of particulate removing apparatus main bodies arranged in parallel and said plurality of particulate removing apparatus main bodies comprising: a cylindrical vessel comprising an inlet port and an outlet port for a diesel exhaust gas; a metallic heat generation body of at least one of a roll-type and a folding-type arranged at said inlet port in said cylindrical vessel; and a heat-resisting filter arranged in a subsequent stage of said metallic heat generation body in order to capture, burn and eliminate particulates in said diesel exhaust gas, wherein said metallic heat generation body is covered with a catalyst accelerating a burning of said particulates, wherein said metallic heat generation body in said plurality of said particulate removing apparatus main bodies is structured so that an ON state/OFF state of said plurality of said particulate removing apparatus main bodies is selectively controlled, and wherein each of said plurality of particulate removing apparatus main bodies comprises an upstream-side thermo-sensor and a downstream side thermo-sensor, respectively placed near said inlet port and said outlet port, and wherein an ON state/OFF state of corresponding said metallic heat generation bodies is controlled on a basis of a temperature difference between an upstream-side temperature detected by said upstream-side thermo-sensor and a downstream-side temperature detected by said downstream-side thermo-sensor.
