PHYSICAL AND/OR CHEMICAL TREATER FOR FLUID

摘要

A fluid treating device for carrying out chemical and/or physical reactions in a flowing fluid stream in contact with a stationary corrugated thin metal member. The converter comprises a housing and fluid inlet and outlet means associated therewith to define an enclosed housing. The metallic element is an accordion folded thin ribbon having perforations through which fluid may pass through the metal strip for ingress or egress and contact with zig-zag corrugations. Catalysts may be supported on the corrugated metal element whereby the device is especially useful in treating exhaust gases. The device with or without catalyst is useful as a particulate trap, especially for diesel engines.
