| Abstract: | In order to prevent electrostatic charge and/or discharge, the unbalanced bipolar ionized wind electrostatic elimination technology is introduced, and a novel unbalanced bipolar electrostatic ionizer is developed to improve the safety level of a polyolefin silo. The unbalanced bipolar electrostatic eliminator and powder electrostatic monitor have been used to control and monitor the mount of static electricity in a pneumatic powder transport facility. The composition, circuit, gas layout of the ion wind power electrostatic elimination control systems for different petrochemical silos were discussed based on electrostatic eliminator and powder electrostatic monitor. The unbalanced bipolar ionized wind electrostatic elimination system was experimentally measured with a polyethylene packaging silo, the results showed that based on the unbalanced bipolar ionized wind static elimination technology of the powder in the pipeline, the positive and negative control voltage can be reasonably adjusted, which can effectively control the charge-to-mass ratio of less than 0.3 μC/kg. |
