| description | Investigation of the JJPW-G100 air-assisted spraying dust suppression device was performed to obtain the reasonable installation angle of the nozzle in the air-assisted spraying dust suppression device. First, an equal-scale physical model was established, and then the effect of the installation angle of the nozzle on the atomizing performance of the air-assisted spraying dust suppression device was investigated in-depth via numerical simulation. Results showed that the installation angle of the nozzle imposed no significant effect on the spraying range of the air-assisted spraying dust suppression device, while the initial falling range in the spray field increased with the increasing installation angle. At the installation angle of over 45°, the loss of droplets at the outlet of the air cylinder disappeared. Mean droplet size of the spraying dust suppression device increased with the increasing installation angle, which first increased and then dropped with the increasing spraying range. The optimal installation angle of the nozzle was determined as 45°, under which the loss of droplets at the outlet of the air cylinder in the air-assisted spraying dust suppression device can be effectively prevented, while the dust suppression device can maintain a small droplet size and large falling range. |
