Abstract
A modular filter for removing particulate matter from gases or liquids is disclosed. The filter includes at least two porous ceramic or ceramic composite modules and a heater structure for regenerating the modules by heating which is integral with the modules. The regenerating structure may also be a ceramic structure. The filter modules may be manufactured using micropyretic synthesis and manufactured to have interconnected porosity. The filter may be used to remove particulates from the exhaust of engines such as engines of land and water vehicles.
Claims25
A regenerative filter comprising;
- a means for filtering;
- and
- a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means, wherein said means for filtering comprises at least two porous ceramic or ceramic composite modules having interconnected porosity and having been manufactured using micropyretic synthesis.
In a land-based vehicle, water-based vehicle, in power generation equipment or in an industrial engine, said vehicle, equipment or engine, including a body and an exhaust system, the improvement comprising:
- a regenerative filter in the exhaust system comprising a means for filtering and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means, wherein said means for filtering comprises at least two porous ceramic or ceramic composite modules having interconnected porosity and having been manufactured using micropyretic synthesis.
In a regenerative exhaust system, the improvement comprising;
- a regenerative filter comprising a means for filtering, and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means, wherein said means for filtering comprises at least two porous ceramic or ceramic composite modules having interconnected porosity and having been manufactured using micropyretic synthesis.
