Abstract
In some examples, an air treatment system includes a filter, an ozone sensor, and a separator configured to separate air into a nitrogen-enriched gas and an oxygen-enriched gas. The filter is configured to remove ozone from an air stream and supply filtered air to the separator. The ozone sensor is configured to sense an ozone level of the filtered air issuing from the filter prior to encountering the separator. The air treatment system may include processing circuitry configured to monitor the ozone level sensed. The air treatment system may be part of an inerting system configured to supply the nitrogen-enriched gas to an ullage space of a fuel tank.
Claims20
An air treatment system comprising:
- a filter configured to receive a flow of treated air comprising ozone and generate a flow of filtered air, wherein the flow of filtered air comprises a lower concentration of ozone than the flow of treated air;
- a separator configured to receive the flow of filtered air from the filter, wherein the separator is configured to separate the flow of filtered air into a flow of nitrogen-enriched gas and a flow of oxygen-enriched gas;
- and
- an ozone sensor configured to detect an ozone level in the flow of filtered air.
An air treatment system comprising:
- a filter assembly comprising:
- a filter configured to reduce an ozone level in a flow of air when the flow of air encounters the filter;
- a filter inlet configured to receive treated air comprising ozone and cause the treated air to encounter the filter;
- and
- a filter outlet configured to channel filtered air from the filter, wherein the filtered air comprises a lower concentration of ozone than the treated air;
- a separator assembly comprising:
- an air separation membrane configured to separate the filtered air into a nitrogen-enriched gas and an oxygen-enriched gas when the filtered air encounters the air separation membrane;
- a separator inlet configured to receive filtered air from the filter outlet and cause the filtered air to encounter the membrane;
- and
- a separator outlet configured to channel the nitrogen-enriched gas from the membrane;
- and
- an ozone sensor configured to detect an ozone level of the filtered air received by the separator inlet.
A method, comprising:
- contacting a filter with a flow of air comprising ozone and removing some portion of the ozone to generate filtered air;
- detecting an ozone level of the filtered air using an ozone sensor;
- and
- separating, via a separator, the filtered air into a nitrogen-enriched gas and an oxygen-enriched gas.
