Type of multi-nozzle combined atomizing dust suppression experimental equipment under the effect of airflow disturbance

A multi-nozzle combined atomizing dust suppression experimental equipment under an effect of airflow disturbance, wherein the equipment comprises a simulated roadway device, water spray based dust suppression device and nozzle position adjustor;

• the simulated roadway device comprises an inlet portion, front divergent portion, simulated roadway body, rear convergent portion and outlet portion;
• the water spray based dust suppression device comprises a dust generation and extraction system and spraying system,
• the dust generation and extraction system comprises a dust generation device, exhaust air duct, exhaust fan and outlet air duct,
• the dust generation device is located at an inlet portion of the simulated roadway device, the inlet portion is connected to the atmosphere, one end of the exhaust air duct is connected to an outlet portion of the simulated roadway device and the other end of the exhaust air duct is connected to the outlet air duct via the exhaust fan;
• the spraying system comprises a water tank, high pressure water pump, confined water pipe, pressure water flow converter and multiple nozzles, the water tank is connected via the high pressure water pump and confined water pipe to the pressure water flow converter which is connected with multiple nozzles;
• the nozzle position adjustor comprises a nozzle slide, slide fixing rod, nozzle sliding rack and electrically-controlled drive system, every nozzle is mounted on the nozzle slide,
• all nozzle slides are mounted on the slide fixing rod which is located on the nozzle sliding rack arranged inside the simulated roadway body, a vertical slideway is located on the nozzle sliding rack and a horizontal slideway is located under the nozzle sliding rack,
• the electrically-controlled drive system comprises a horizontal drive system which controls horizontal position change of the nozzle sliding rack on the horizontal slideway and a vertical drive system which controls vertical position change of the slide fixing rod on the vertical slideway.
