<p>PROBLEM TO BE SOLVED: To obtain a connection support structure of a filter tube for dust collector in which a filter tube is not floated with gas pressure at back-washing, and it is easily built in. SOLUTION: In the connection support structure of a filter tube by which plural filter tubes A1, A2, are connected to a tube plate B having a through hole C through which the filter tubes penetrate and supported inside a can body being a main body of the dust collector, a bellows tube 4 is attached to the upper end part of the filter tube A2 an annular protective member 1 is attached to the lower end part of the filter tube A1, an annular support member 3 abutting the protective member 1 and supporting the filter tube A2 is attached on a through hole part of the tube plate the contact part of the support member 1 with the support member 3 is made into a circular contact, and the diameter D1 of a contact circle is made to be approximately equal to the mean diameter D2 of the inner and outer diameters of the bellows tube.</p> |
