PROBLEM TO BE SOLVED: To provide a new high temperature gas filtration system and a reproducing process of the system.SOLUTION: A system includes: a filter container; a tube sheet for separating the inside of the container into two areas; and a plurality of filter elements. Two or more grouped filter elements are connected to the tube sheet by a clean gas end and a raw material gas section extends into a raw material gas area. Two or more plenum chambers are received into a clean gas area, the clean gas end of the filter element is received in units of groups, and the respective plenum chambers are provided with a gas exchange opening. This system includes a backflow device provided with a backflow gas reservoir and a backflow gas pipe on each group of the filter element. The backflow gas pipe has an exit disposed in the clean gas area of the container. The free cross section of the exit of the backflow gas pipe is about 10 to about 90% of the gas exchange opening. |
