| titleOfInvention | Automatic nitrogen oxide monitoring device |
| abstract | The utility model discloses an automatic nitrogen oxide monitoring device, which comprises a display and a control panel arranged at the front end of a shell, wherein a sampling tube is arranged at the back of the shell, and an ozone generator, a dryer and a photomultiplier which are connected to the sampling tube are arranged in the shell; the inside of the shell is also provided with a filtering mechanism connected to the sampling pipe; the filtering mechanism comprises a concave filtering base arranged in the shell through a mounting plate, an air inlet connected with the sampling pipe is formed in the filtering base, an air outlet is formed in the center of the filtering base, a filtering membrane is arranged on the filtering base located on the inner side of the air inlet, and a glass sheet is arranged above the filtering membrane. According to the utility model, the sampled gas is filtered by the filtering device, dust and impurities in the sampled gas are filtered, and the dust and impurities are prevented from entering the photomultiplier, so that the reliability of a monitoring result is ensured, and the service life of the photomultiplier is prolonged. |
