Abstract
An exhaust gas filter comprises an outer tube, a plurality of center-closing filter units each having an isolation plate; and a plurality of center-opening filter units having an annular isolation plate, two kinds of filter units being arranged alternately in the outer tube. The isolation plate and annular isolation plate are enclosed by flammable fibers. When a contaminated gas goes through the flammable fibers, it can be filtrated.
