REVERSE-CLEANING APPARATUS OF A FILTER FOR A HIGH PRESSURE DUST COLLECTOR

摘要

PURPOSE: The filter back washing apparatus of a high pressure dust collector is provided to improve the back washing efficiency of a filter by using a completely sealed back washing ejector. CONSTITUTION: A dust collecting container is divided into a buffer region(42) and an introducing gas region(44) by a filter fixing plate(30) and receives processing gas. A plurality of dust collecting filters(1) is installed at the filter fixing plate and is located at the introducing gas region. Filter caps(50) is installed at the buffer region and seals the dust collecting filters. A processing gas discharging pipe(72) is in connection with respective filter caps in order to discharge processing gas through the dust collecting filters. A back washing gas introducing pipe(62) introduces back washing pulse gas to the filter caps.
