| Abstract: |
| In order to study the dust removal efficiency of high-temperature flue gas from rubber industry combustion in the plate electrostatic precipitator，the physical model of plate electrostatic precipitator was established，its internal complex flow field characteristics was studied，the influence of rubber flue gas in the electric field distribution and dust removal efficiency of the equipment at different temperatures were analyzed.Numerical simulation of the dust collection process for flue gas at 323～673 K was established by using Fluent software.The results showed that at the same discharge voltage，the higher the temperature，the lower the current density，the smaller the electric field strength，and electrostatic force of fine particles in flue gas.Elevated flue gas temperatures also enhanced the interaction between particles and fluids，manifested in the increase in gas viscosity and particles drag force，thereby reduced the purification efficiency，particularly the decrease of purification efficiency was more obvious when fine particles size was below 1 μm. |
