| titleOfInvention | a smoke meter |
| abstract | The utility model provides a smoke and dust measuring instrument, which comprises a main body and a cyclone cavity. The smoke and dust enters the main body through the cyclone cavity, and the main body is used to measure the concentration of the smoke and dust. The cyclone cavity of the utility model passes through the first wall and the second wall. The first wall is configured as a multi-level annular stepped shape, the second wall is configured as a multi-level annular inverted stepped shape corresponding to the first wall, and the air inlet end of the cyclone cavity is provided on the At the position where the diameter of the cyclone cavity is larger, the outlet end of the cyclone cavity is set at the position where the diameter of the cyclone cavity is smaller, so that the flue gas entering the cyclone cavity through the air inlet end generates a cyclone, so that a cyclone is generated. The flue gas mixing is more uniform, thereby improving the detection accuracy, reducing the detection error caused by the uneven mixing of the flue gas, and under the limitation of the first wall and the second wall, the measured flue gas can be The large particles of impurities can be effectively intercepted, avoiding the influence of large particles of impurities on the detection accuracy and damage to the measuring instrument. |
