Facing to the combustion quality monitor null waste gas of soot method of detection and the device

摘要

PROBLEM TO BE SOLVED: To miniaturize a device for detecting soot in exhaust gas, and to easily detect the soot in the exhaust gas at a low cost.;SOLUTION: A transparent cartridge which is opened so as face the inside of an exhaust gas duct 11 is attached to an opening formed at the bottom wall surface 11a of the exhaust gas duct 11, light pervious oil 16 which has a liquid surface in the vicinity of the opening of the cartridge 14 and captures and sediments the soot accompanied by the exhaust gas is housed in the cartridge 14, a floodlight projector 21 for projecting inspection light R into the oil 16 in the cartridge 14 is provided, a photelectric detector 22 for detecting the luminous intensity of the inspection light R is provided in the oil 16, a transparency degree detector 23 for detecting the degree of the transparency of the oil 16 from the luminous intensity of the inspection light R is provided and the amount of the soot in the exhaust gas is detected from the time change quantity of the degree of the transparency of the oil 16 is detected in a soot amount detection part 24.;COPYRIGHT: (C)2011,JPO&INPIT
