GAS MEASURING APPARTUS OF INDUSTRIAL CHIMNEY

摘要

The invention of the gas measuring devices for industrial chimneys, to which the present invention is in the side of the chimney is fixedly mounted to the outside, the inside of the light source 11 and the lens 12 and the transmitting and receiving unit having a detector (14) (10); Through the one side of the chimney from the side of the transmitting and receiving section 10 is provided to the inside of the transverse tube-like, and some are vertically opened so that the gas to form a hole 21 to pass through the exhaust gas, the gas provided with a hole 21, the both side surfaces of the window to allow light to pass through, respectively (22), the inner end portion of the sensing unit having a mirror 23 for reflecting light which is incident through the window (22) (20); The front end portion of the transmitting and receiving unit 10 and the air supply pipe is provided over the sensing unit 20, 31, a gas hole 21 and the air supply pipe to inject air toward the window 22 of the two sides (31) an air supply part 30 comprises an air nozzle 32 is provided in; (108) built along the air supply pipe 31, one end is directed to the detector 14 of the transmitting and receiving section 10, the other end is provided toward the end portion side of the mirror reflection surface 23 of the sensing section 20 is provided as a more accurate signal transmission unit 40 made of a fiber-optic cable (41) and secure the gas measurement and further improve the efficiency of the inspection apparatus is characterized in that, while improving the safety of operation and reduction of labor and time.
