To provide a compact bag filter equipment in which the ratio of powder to be re-stuck to filter clothes is reduced, thus, shaking-down effect therefor can be increased, the increase of differential pressure and a clogging can surely be prevented, and the service life of the filter clothes can be prolonged, and to provide a driving method thereof.
The bag filter equipment is constituted so that, at the time when, with a group of filter clothes at least in one line as one section, the whole is made into a plurality of sections A, B and C, the section on the side of a cleaning chamber 4 is partitioned by diaphragms 13. Further, a movable shielding board 15 for shielding the flow of gas at a cleaning gas outflow part corresponding to at least one section is set inside the cleaning chamber 4 so as to almost be contacted with the upper end parts of the diaphragms 13 located at the parts upper than a pulse jet injection tube 10, and further, the movable shielding board 15 is made movable to a horizontal direction by using a driving means 18, and the flow of gas at least in one section in the respective sections is allowed to be shielded in succession.
