Numerical Simulation of High-pressure Spray Coal Dust Capture Technology Based on Fluent Software and Its Application
In order to set optimal atomization parameters and effectively reduce the coal dust concentration,in coal handling workplace,taking the Datang Xilinhaote mineral company M102 drive room as an example,based on collision model,breakup model and evaporation model,coupling relationships between atomization pressure,nozzle diameter and dust removal efficiency with different spray parameters were simulated by using Fluent software.The simulation results show that increase of pressure can appropriately improve uniformity diameter distribution and velocity of particle,increases dust particles capture probability,and that when pressure is 8.5 MPa the best coal dust capture effect can be produced--the efficiency of dust falling at each measuring point is over 90％.
