Abstract
Defect detection systems include at least one nozzle for delivering a CO2 particulate fluid to an inlet end of a plugged honeycomb body. Defects in the honeycomb, if any, are determined by monitoring CO2 particulate flow at the outlet end of the honeycomb body. Methods for detecting defects in plugged honeycomb bodies are also disclosed.
Claims20
A system for detecting defects in a plugged honeycomb body, comprising:
- a CO2 particulate source;
- at least one nozzle in fluid connection with the CO2 particulate source, the at least one nozzle delivering a fluid stream comprising CO2 particulates to an inlet end of the plugged honeycomb body;
- and
- a detection system for monitoring CO2 particulates in a filtered fluid stream exiting an outlet end of the plugged honeycomb body;
- and
- a conversion apparatus in fluid connection with the CO2 particulate source, wherein the conversion apparatus generates CO2 particulates from a liquid CO2 source,
- wherein the conversion apparatus comprises at least one of an operating temperature ranging from about −25° C. to about 25° C. and an operating pressure ranging from about 200 psi to about 1000 psi.

A method for detecting defects in a plugged honeycomb body, comprising:
- delivering a fluid stream comprising CO2 particulates to an inlet end of the honeycomb body, wherein the fluid stream flows through at least one channel of the honeycomb body and exits the honeycomb body through an outlet end;
- and
- detecting CO2 particulates in a filtered fluid stream exiting the outlet end of the honeycomb body with a detection system comprising at least one of a light source and an imaging device;
- wherein CO2 particulates are generated from a liquid CO2 source:
- and
- wherein the method further comprises at least one of cooling the liquid CO2 source to a temperature ranging from about −25° C. to about 25° C. and pressurizing the liquid CO2 source to a pressure ranging from about 200 psi to about 1000 psi.
