Title: Method and apparatus for removing dust from gas
Inventor: KOBAYASHI KENJI
IPC: B01D47/02
Filed: 1989-06-27
Abstract: PURPOSE:To improve dust removing efficiency by a method wherein the gas requiring its dust to be removed is supplied into the gas blow-off pipes together with a liq. and they are blasted in an atomized stream into the liq. with its ion concn. adjusted. CONSTITUTION:Exhaust gas Gw is blasted into water W through a number of blow-off pipes 4 with their ends 4A open under the water to produce fine air bubbles, thereby forming air bubble layers 7. The streams of the dust contg. exhaust gas Gw are diffused and impinged by inertia against one another in such air bubble layers 7 so as to remove the dusts therefrom. The blasting height H of the exhaust gas Gw is adjusted by the concn. and particle size of the dusts therein. The dust concn. of a gas G is automatically controlled by cascading to a controller for controlling the height H. In this way, the dust removing effect can be improved.
