Abstract
A multi-nozzle combined atomizing dust suppression experimental equipment under the effect of airflow disturbance includes a simulated roadway device, water spray based dust suppression device and nozzle position adjustor. The simulated roadway device includes an inlet portion, front divergent portion, simulated roadway body, rear convergent portion and outlet portion. The water spray based dust suppression device includes a dust generation and extraction system and spraying system. The dust generation and extraction system includes a dust generation device, exhaust air duct, exhaust fan and outlet air duct while the spraying system includes a water tank, high pressure water pump, confined water pipe, pressure water flow converter and multiple nozzles. The nozzle position adjustor includes a nozzle slide, slide fixing rod, nozzle sliding rack and electrically-controlled drive system which controls the change of horizontal position and vertical position of the nozzles.
