[Purpose]
To provide a polluting gas desulfurization apparatus of simple structure
able to effectively remove sulfur from a polluting gas, reduce gas flow
pressure loss, and significantly reduce the consumption of electrical
power consumed by the apparatus.
[Means]
A drum is rotationally supported at its radial center by a horizontal
shaft within a fixed duct having a gas inlet port at one end and a gas
outlet port at the other. The right and left sides of the drum, and its
circumferential surface, are lattice-like structures, and the internal
space of the drum is filled with gas-liquid contact filler pieces. A
slurry holding tank is disposed beneath the rotating drum, the slurry
being pumped upward by a circulation means and discharged onto the top of
the circumferential surface of the drum at a point offset from the
horizontal shaft in the desired direction of rotation, thus forming a
mechanism able to rotate the drum from the weight of the slurry only and
thus eliminating the need for an electric motor.
A compact and energy-efficient polluting gas desulfurization apparatus
which reduces gas flow pressure loss and the consumption of electrical
power. A drum is rotationally supported at its radial center by a

and its circumferential surface are lattice-like structures, and the
internal space of the drum is filled with gas-liquid contact filler
pieces. A slurry holding tank is disposed beneath the rotating drum.
Slurry, which is pumped upward by a circulation means, is discharged onto
the top of the circumferential surface of the drum at a point offset from
the horizontal shaft along the radial axis, thus forming a mechanism able
to rotate the drum from the weight of the slurry only and thus
eliminating the need for an electric motor.
