Abstract
A modular membrane filter for gases liquid and particulate matter is disclosed, the filter comprising at least two porous ceramic or ceramic modules. A regenerative filter is also disclosed comprising a means for filtering; and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means.
Claims31
A regenerative membrane filter comprising:
- a means for filtering including at least one porous ceramic or ceramic composite membrane having been manufactured using micropyretic synthesis;
- and
- a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means and further being formed in situ with said filtering means.
In a land-based vehicle, water-based vehicle, in power generation equipment or in an industrial engine, said vehicles, equipment or engine, including a body and an exhaust system, the improvement comprising:
- a regenerative membrane filter in the exhaust system including a means for filtering which comprises at least one porous ceramic or ceramic composite membrane having been manufactured using micropyretic synthesis and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means and further being formed in situ with said filtering means.
In a regenerative exhaust system, the improvement comprising:
- a regenerative membrane filter comprising a means for filtering which comprises a porous ceramic or ceramic composite membrane having been manufactured using micropyretic synthesis, and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means and further being formed in situ with said filtering means.
In a land-based vehicle, water-based vehicle, in power generation equipment or in an industrial engine, said vehicles, equipment or engine, including a body and an exhaust system, the improvement comprising:
- a regenerative membrane filter in the exhaust system comprising a means for filtering which includes at least one porous ceramic or ceramic composite membrane manufactured using micropyretic synthesis;
- and
- a heating element having high resistivity, or having high emissivity or having both high resistivity and emissivity, for regenerating said means for filtering, said heating element being integral with said filtering means and further being formed in situ with said filtering means.
A modulated regenerative membrane filter for gaseous, liquid and particulate matter, wherein the modules in said filter are porous ceramic or ceramic composite membranes, said membranes having been manufactured using micropyretic synthesis, the filter comprising:
- at least two porous ceramic or ceramic composite membranes;
- and
- a means for regenerating said filter, said means for regenerating being integral with said membranes and further being formed in situ with said filtering means.
