Abstract

A gas desulfurization apparatus is disclosed. The apparatus includes a cylinder casing containing a number of rotating cylinders. Secured to each end of the rotating cylinders is a circular end plate, and within each of the cylinders is fill material having voids or cavities thereon. A desulfuring slurry reservoir is located in the base of the cylinder casing and a waste slurry pit is similarly connected the casing. A lifter is associated with each of the rotating cylinders and is arranged so that, as the cylinders rotate, a quantity of desulfuring slurry from the slurry reservoir is transferred into the associated rotating cylinder.

Claims

1. A gas desulfurization apparatus comprising:

(a) a cylinder casing having an axis and forming a gas inlet and a gas outlet;

(b) a plurality of rotating cylinders in said cylinder casing, each said rotating cylinder axially parallel to said cylinder casing axis and arranged to rotate about said cylinder casing axis, and having an open end adjacent said cylinder casing gas inlet and an open end adjacent said cylinder casing gas outlet;

(c) a drive system means disposed in said cylinder casing attached to each of said cylinders for rotating said cylinders about said cylinder casing axes;

(d) a gas seal disc in said cylinder casing perpendicular to said cylinder casing axis and extending between said cylinder casing and said rotating cylinders for directing gas flow through said rotating cylinders;

(e) a reservoir in said cylinder casing for storing a desulfuring slurry;

(f) a waste slurry pit connected to said cylinder casing; and

,

(g) a lifter attached to each said rotating cylinder to transfer a quantity of desulfuring slurry from said slurry reservoir into said associated cylinder during the rotating of said cylinders.

2. The gas desulfurization apparatus of claim 1, further including independent filling material having cavities therein disposed inside said rotating cylinders.

3. The gas desulfurization apparatus of claim 2, further including a ring-shaped end plate disposed over each end of said rotating cylinders.

4. The gas desulfurization apparatus of claim 1, further including a rotating shaft axially disposed inside said cylinder casing and said rotating cylinders integrally connected to said rotating shaft.

5. The gas desulfurization apparatus of claim 1, wherein said gas seal disc is connected to said rotating cylinders adjacent said rotating cylinder open ends adjacent to said cylinder casing gas inlet.
