Abstract:
PURPOSE: A dust-removing apparatus capable of improving dust removing efficiency, increasing economical efficiency by reducing pressure drop in a cyclone, allowing no accompanying equipment such as special blowers and additional conduit tubes to need for absorbing objective gases containing dusts and integrating conventional dust removing processes is provided which reduces space, operation cost and initial investment cost. CONSTITUTION: The apparatus comprises a straight flow cyclone comprising an absorption fan(14) for absorbing dust-containing gas through an absorption conduit tube(11), a rotary bane(16) for generating rotary force at the absorbed gas by the absorption fan and a cylindrical body conduit tube(18) for separating dust-containing gas rotated by the rotary bane by centrifugal force; a standard cyclone(30) comprising a cylindrical conduit tube for separating dust from the dust-containing gas and depositing into a dust sedimentation tank(39) and a cylindrical conduit tube connected to the lower part of the cylindrical conduit tube and opened toward the dust sedimentation tank at its lower part.
