Abstract
A filter comprising a filter element with a filtering medium, mounted in a housing having a first end and a second end, and a passageway A removable generator to provide heated fluid for regenerating the filter element is to be connected to the housing adjacent the second end The second end of the filter element is constructed so as to permit a first portion of the heated fluid to flow toward the first end of the filter element, and the passageway is to allow a second portion of the heated fluid to flow from the second end to the first end, bypassing the filtering medium A flow director is positioned adjacent to the first end of the filter element for directing the second portion of the heated fluid discharged from the passageway toward the first end of the filter element.
Claims24
A filter, comprising a housing;
- a filter element mounted in said housing and having a first end and a second end, said filter element including a filtering medium therein between said first and second ends and a passageway extending therethrough between said first and second ends;
- a generator sized and shaped so as to be connected to said housing for introducing a heated fluid to said housing adjacent said second end of said filter element for regenerating said filter element, said second end of said filter element being constructed so as to permit a first portion of the heated fluid to pass therethrough and flow toward said first end of said filter element, said passageway being constructed so as to allow a second portion of the heated fluid to flow from said second end of said filter element to said first end of said filter element without passing through said filtering medium;
- and a flow director positioned in said housing adjacent said first end of said filter element for directing the second portion of the heated fluid discharged from said passageway toward said first end of said filter element.
A filter, comprising a housing;
- a filter element mounted in said housing and having a first end and a second end, said filter element including a filtering medium therein between said first and second ends and a passageway extending therethrough between said first and second ends;
- a generator sized and shaped so as to be connected to said housing for introducing a heated fluid to said housing adjacent said second end of said filter element for regenerating said filter element, said second end of said filter element being constructed so as to permit a first portion of the heated fluid to pass therethrough and flow toward said first end of said filter element, said passageway being constructed so as to allow a second portion of the heated fluid to flow from said second end of said filter element to said first end of said filter element without passing through said filtering medium;
- and a pump for creating a low pressure condition in said housing while the fluid passes through said filter element.
A method for regenerating a filter including a housing and a filter element, the filter element being mounted in said housing and having a first end, a second end, a filtering medium therein between the first and second ends, and a passageway extending therethrough between the first and second ends, said method comprising the steps of:
- introducing a heated fluid to the housing adjacent the second end of the filter element;
- transmitting a first portion of the fluid through the second end of the filter element and discharging the first portion of the fluid from the filter element through the first end of the filter element;
- transmitting a second portion of the fluid through the passageway toward the first end of the filter element such that the second portion of the fluid bypasses the filtering medium;
- directing the second portion of the fluid discharged from the passageway toward the first end of the filter element;
- and
- discharging the fluid from the housing after the fluid has passed through the filter element.
