Abstract

See full text

The present invention discloses a Fe—Al intermetallic compound filter element and a preparation method thereof, which relates to the field of powder metallurgy and filtration technology. In view of the drawback in the prior art that using a fiber felt as a filtration layer reduces stability and reliability of a filter, the present invention provides an Fe—Al intermetallic compound filter element, which comprises: at least two filter-element parts, and a rebar connecting the at least two filter-element parts transversely by means of welding, wherein, the filter-element parts each comprises at least two segments of Fe—Al intermetallic compound filter-element powder tube and a connector connecting the at least two segments of Fe—Al intermetallic compound filter-element powder tube end-to-end by means of welding; and wherein, the at least two segments of Fe—Al intermetallic compound filter-element powder tube each comprises a substrate framework and a surface filtration membrane.
