| description | The invention discloses a smoke dust generating device with a strip-shaped outlet, which comprises an air knife and a plurality of material blowing devices, quantitative dust is blown into a cavity of the air knife through a variable-frequency high-pressure fan and an automatic feeder in each material blowing device, and the air speed and the smoke dust mass flow rate at the inlet of the air knife are monitored by virtue of a pipeline type anemometer and a particle flow meter. The long rectangular strip-shaped smoke outlet device solves the current situation that a long rectangular strip-shaped smoke outlet device is lacked on the market at present, smoke with uniform wind speed and mass flow rate can be continuously transmitted to the long strip-shaped outlet by controlling the wind speed of the air knife inlet and the mass flow rate of the smoke, a smoke environment with uniform concentration is established, and therefore relevant laser smoke interference resistance tests are carried out.
