<p>PURPOSE:To efficiently remove granular materials by providing filter means opposite to discharge electrodes provided in the flow of a gas contg. the granular materials, impressing a high voltage between the discharge electrodes and the filter means and controlling the gaseous flow passing the filter means. CONSTITUTION:The discharge electrodes 6a, 6b are provided in the gaseous flow contg. the granular materials and the filter means 8a to 8d are disposed opposite to the discharge electrodes. The high voltage is impressed between the discharge electrodes and the filter means by a high voltage electrode 5 and the gas flow passing the above-mentioned filter means is controlled by a gas extracting means 16. As a result, the granular materials in the gas are efficiently collected and removed.</p> |
