APPARATUS FOR THE CLEANING OF DUST LADEN GAS

摘要

A filter for the cleaning of dust laden possibly hot gas includes ceramic filter candles which are closed at one end and positioned in multiple levels one above the other and are connected to laterally spaced apart candle supporting clean gas collectors. The collectors and the filter candles within one level form a filter module which is divided into several mutually separate filter segments in the shape of a circular sector. The collectors of each filter segment are connected to a clean gas collecting channel located on the same level. A collector free space remains at the center of each module. A cleaning lance protrudes into each clean gas collecting channel either directly or indirectly for the supply of pressurized, pulsed cleaning gas. This allows the groupwise cleaning of the filter candles and substantially reduces the amount of cleaning gas required for the cleaning of the whole filter unit.
