Computer Simulation on Key Structure Parameters of Foam Generator for Dust Control in Underground Coal Mines

Abstract:

Foam is a high efficient technology for controlling dust in underground coal mine,and foam generator is one of the core components of the technology. Aiming at designing the key structural parameters of foam generator scientifically, the velocity and pressure distribution of foam generator under different parameters were simulated and displayed by CFD (Computational Fluid Dynamics) software. The results show that the intensity of gas-liquid mixture in foam generator reaches the maximum when the vortex generator is 24mm away from the throat and the baffle with a 45° angle. Under the circumstances, the pressure is well-distributed around the vortex generator and the outlet of foam generator, and the foaming effect best.
