Abstract
A filter system wherein a cylindrical shell having open ends and a gas-impervious wall with means for supporting a filter tube coaxially within the shell to form an annular chamber therebetween has means for securing the filter tube to the other open end, such that gases from the enclosure must pass through the filter tube into the annular chamber and then out of the cylindrical shell. A jet pulse means is provided to provide a jet pulse of fluid to the annular chamber to flex the filter tube inwardly to dislodge solids collected on the interior surface of the filter tube.
Claims23
A filter system for separation of particulate material from a flow of gas containing the same wherein said flow of gas is passed to an enclosure comprising:
- a cylindrical shell having an impervious wall, said shell open at both ends thereof and having a constricted section adjacent one open end;
- means for supporting the cylindrical shell within the said enclosure such that gases entering the enclosure are discharged through said cylindrical shell;
- means adjacent said one open end for supporting a filter tube coaxially within said cylindrical shell spaced from said impervious wall to form an annular chamber therebetween;
- means for securing said filter tube to the other end of said cylindrical shell to seal said other end such that gases entering said cylindrical shell pass through said filter tube and into said annular chamber prior to discharge through said one open end;
- and
- means to provide a jet pulse of fluid to said annular chamber to flex the filter tube inwardly relative to said impervious wall.
A filter system for separation of particulate material from a flow of gas containing the same wherein said flow of gas is passed to an enclosure comprising:
- a cylindrical shell having an impervious wall, said shell open at both ends thereof and having a constricted section adjacent one open end;
- means for supporting the cylindrical shell within the said enclosure such that gases entering the enclosure are discharged through said cylindrical shell;
- a solid insert having a diameter less than the diameter of said cylindrical shell is provided therein spaced from the impervious wall of the shell and from said one open end;
- a ring-like member positioned between said solid insert and said open end, with said insert connected to said ring-like member by a plurality of spaced connectors;
- means for securing a filter tube to said solid insert, coaxially within said cylindrical shell spaced from said impervious wall to form an annular chamber therebetween;
- an inwardly directed flange on the other end of said cylindrical shell;
- means for securing said filter tube to said inwardly directed flange to seal said other end such that gases entering said cylindrical shell pass through said filter tube and into said annular chamber prior to discharge through said one open end;
- and
- means to provide a jet pulse of fluid to said annular chamber to flex the filter tube inwardly relative to said impervious wall.
