Abstract
A wire mesh filter is made from a knitted wire sock, folded along its length, and then wound into a spiral, and is useful for diesel traps and other particulate filters that are regenerable by heating the filter.
Claims6
A wire mesh filter, comprising:
- a knitted wire mesh having a longer dimension and a shorter dimension, folded along the longer dimension so that the shorter dimension is effectively halved, and rolled into a spiral geometry.
A regenerable particulate trap having a wire mesh filter, the filter being regenerated by resistive heating, wherein the improvement comprises a wire mesh filter, comprising:
- a knitted wire mesh having a longer dimension and a shorter dimension, folded along the longer dimension so that the shorter dimension is effectively halved, and rolled into a spiral geometry.
