抄録

A novel flange-type electrostatic neutralizer has been developed, which can be used to effectively reduce the static charges on powder in pneumatic powder transport process. The flange-type electrostatic neutralizer, provided with eight nozzle neutralizers, blows ionized air (0.1MPa to 0.3MPa) toward the charged powder within the pipe as well as to protect the needle electrode from the deposition of powder. The current study aimed to improve the conventional version of flange type neutralizer for practical use by adding a function of explosion protection of pressurized type. The evaluation of the neutralizer was also conducted with a real industrial pneumatic powder transport process. As the results, it is shown that the improved version, the pressurized type of neutralizer is used for producing air ions to reduce the static charges on powder in an industrial situation with explosive atmosphere.
