Characteristic and design of electrostatic precipitator in sulphuric acid plant

The electrostatic precipitator of sulphuric acid plant needs high dust collection efficiency, excellent sealing, and better electrical and thermal insulation to meet high concentration dust. The corresponding measures should be taken in design. The choice of process parameters should be based on characteristic of off-gas and dust. The installation of gas distributor and choice of discharge electrodes and collecting electrodes are made through simulating test. The power source and load should be matched. Thermal expansion should be considered to ensure no deformation of shell and internal occurring in operation. And the unstable operation of plant should be considered.
