Abstract
An apparatus, system, and method are disclosed for a filter for filtering a dosing fluid in an exhaust aftertreatment system. The filter may comprise a dosing tank configured to contain a dosing fluid, a filter media disposed within the dosing tank, and a support structure supporting the filter media to form a pathway for a flow of dosing fluid. Beneficially, the apparatus, system, and method of the present invention reduce the cost of operation and manufacture of the SCR system.
Claims7
A method for filtering a mono-nitrogen oxide (NOx) reducing agent in an exhaust aftertreatment system to chemically reduce pollutants in an exhaust stream, the method comprising:
- containing a mono-nitrogen oxide (NOx) reducing agent in a dosing tank, the dosing tank containing a filter media and a heating element within the dosing tank exposed to the mono-nitrogen oxide (NOx) reducing agent;
- transferring heat from the heating element through the mono-nitrogen oxide (NOx) reducing agent to the filter media;
- urging the mono-nitrogen oxide (NOx) reducing agent through the filter media;
- and
- causing the mono-nitrogen oxide (NOx) reducing agent to exit the dosing tank, after the mono-nitrogen oxide (NOx) reducing agent has passed through the filter media.
