Problems with electric demisting
Thread Content
Dear experts, in my factory the electric demisting voltage and secondary voltage are around 70,000 volts, while the secondary current is only a little over 40 milliamps. I’m not sure what the reason for this is.
First, ask whether it is level 2 electrostatic demisting or level 1 electrostatic demisting. If it is only level 1 electrostatic demisting, with 40 milliamps and 70,000 volts, that value is a bit low. If it is the second stage of level 2 electrostatic demisting, then it’s normal, as the amount of acid mist decreases. Reasons: Treatment methods: (1) The gas flow rate is too high. (1) Reduce the gas flow rate. (2) The inlet gas temperature is either too high or too low. (2) Adjust the inlet gas temperature to the required level. (3) The grounding resistance is too high. (3) Lower the grounding resistance. (4) There is a break in the output cable connection or poor contact. (4) Restore the circuit connection. (5) The electrode wires are covered by sublimated sulfur. (5) Clean off the sublimated sulfur. Also, check whether there is poor contact in the grounding wires of the electrode wires
