Abstract

PURPOSE: To make it even to sweep away dust by arranging an acoustic-wave generator, which generates a low-frequency wave evenly, at a proper position in the clean gas chamber of a bag filter having filter cloth tubes made of glass fiber arranged in its casing at adequate intervals.
CONSTITUTION: The bag filter having filter cloth tubes 2 made of glass fiber arranged in casing 1 which exhaust duct 1b equipped with dust-containing gas intake duct 1a and outlet damper 5 is provided with at least one acoustic-wave generator 6, generating a low-frequency wave of severalWabout 200Hz evenly, at a proper position in gas cleaning chamber 3. The above-mentioned constitution applies the entire surface of each filter cloth 2 with vibrations of several mm in amplitude through gas cleaning chamber 3 to sweep away dust sticking to the internal surface and it is taken out by way of hopper section 1C. Defectives such as the local exfoliation of the dust can therefore be eliminated without bending and tensing filter cloth tubes 2 extremely.
