A SYSTEM FOR REGENERATING CERAMIC CANDLE FILTERS USING AXIAL MOVEMENT OF METALLIC MESH

摘要

A filter cake removable system for a fluidized bed gasification system, the system comprising: at least a ceramic candle filter (1) suspended from a ceramic filter tube sheet (4); a metallic mesh (2) encapsulating the said ceramic candle filter (1), the metallic mesh (2) and ceramic candle filter (1) maintaining a significant gap; suspended from a metallic mesh tube sheet (4) placed horizontally below the ceramic filter tube sheet (4); wherein said metallic mesh tube sheet (4) is supported on a support structure element (7) welded to an inside filter vessel wall; wherein coil suspension (6) is set up in the circumferential space between fixed ceramic filter tube sheet and metallic mesh tube sheet to facilitate smooth vertical movement of metallic mesh tube sheet; wherein said metallic mesh tube sheet (4) bottom is coupled to a corrugated metallic shaft (5); wherein said rotation of corrugated metallic shaft tends up- down movement in metallic mesh tube sheet(4) and initiates movement of metallic meshes in axial direction; and wherein said axial movement of metallic meshes over ceramic candle filters (1) removes filter cake from ceramic candle filters (1).
