| Abstract: | In order to study the optimal magnetization conditions of magnetized water for dust removal,and improve the utilization rate of water,the surface tension and viscosity of water under different magnetization conditions were measured experimentally,and the spray pressure and magnetization conditions with the optimal dust removal performance of magnetized water were obtained by numerical simulation with ANSYS Fluent.The results showed that the spray concentration of unmagnetized water was larger and the particle size was smaller when the spray pressure was 5 MPa.Under this pressure,when the magnetic field intensity was 150 mT and the magnetization time was 80 s,the average particle size of magnetized water droplets decreased by 39.6%,the max particle size decreased by 16.4%,the droplet size was small and distributed evenly,and the dust removal performance was significantly improved.It can provide theoretical guidance for alleviating the problem of dust pollution in underground mine. |
