<P>PROBLEM TO BE SOLVED: To provide a cartridge filter for a pulse jet dust collector which is provided with an effect of shaking off dust more evenly than before by improving a negative pressure region generated in its upper to center part and moderating the deflection of the inner pressure distribution due to convergence of jet current on the bottom part of the cartridge. <P>SOLUTION: The cartridge filter is to be used for a pulse jet dust collector which can jet back washing jet current for shaking off dust adhering to and deposited on a filter body 1 obtained by folding a filter cloth just like pleats and forming the entire filter cloth to be cylindrical: and in the first invention, a taper tube 2 having a truncated conical shape is installed in the inner face part of the filter body 1 and in the second invention, the lower end part of the filter body 1 is closed with a bottom plate having a concave shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
