Abstract
An agitator for agitating liquids in an agitator vessel for suspending solids and dispersing gas in a liquid, in particular in an absorber of a flue gas desulfurizing plant, includes an agitator vessel, an agitator shaft extending into the agitator vessel, and an agitating propeller mounted to the agitator shaft within the agitator vessel. The agitator shaft is hollow to define an interior space for conducting gas into the agitator vessel and injecting gas on the pressure side of the agitating propeller into the liquid.
Claims57
An agitator for agitating liquids, with a gas being added to the liquid, in particular for suspending solids and dispersing gas in the liquid in flue gas desulfurizing plants, said agitator comprising:
- an agitator shaft extending into an agitator vessel, said agitator shaft being hollow to define an interior space for conducting gas into the agitator vessel;
- and
- an agitating propeller mounted to the agitator shaft within the agitator vessel;
- and
- a gas injection device connected to the one end in fixed rotative engagement with the agitator shaft for introducing gas into the agitator vessel at an axial distance downstream of the agitating propeller in the conveying direction of the liquid.
An agitator for agitating liquids, with a gas being added to the liquid, in particular for suspending solids and dispersing gas in the liquid in flue gas desulfurizing plants, said agitator comprising:
- an agitator shaft extending into an agitator vessel;
- a hub connected in fixed rotative engagement with the agitator shaft for conducting gas into the agitator vessel, said hub being hollow to define an interior space;
- an agitating propeller mounted to the agitator shaft within the agitator vessel for axially moving a liquid in the agitator vessel in a conveying direction;
- and
- a gas injection device, connected in fixed rotative engagement to the hub to rotate conjointly with the hub, for injecting gas into the interior of the agitator vessel, wherein the gas injection device is disposed at an axial distance downstream of the agitating propeller in the conveying direction of the liquid.
An agitator for agitating liquids, with a gas being added to the liquid, in particular for suspending solids and dispersing gas in the liquid in flue gas desulfurizing plants, said agitator comprising:
- an agitator shaft extending into an agitator vessel;
- a plurality of pipes connected in a fixed rotative engagement to the agitation shaft and disposed about an outer circumference of and extending longitudinally in the direction of the agitator shaft for conduction of gas and introduction into the agitator vessel;
- and
- an agitating propeller mounted to the agitator shaft within the agitator vessel wherein the pipes end at an axial distance downstream of the agitating propeller in a conveying direction of the liquid.
An agitator, comprising:
- a gas-conducting receiving gas from a gas source and having an interior space terminating in an outlet means for introducing a gas into a vessel containing a liquid;
- and
- a propeller mounted to the gas-conducting device for stirring the liquid and dispersing the gas in the liquid wherein the outlet means is disposed at an axial distance downstream of the propeller in a conveying direction of the liquid.
An agitator for agitating liquids, with a gas being added to the liquid, in particular for suspending solids and dispersing gas in the liquid in flue gas desulfurizing plants, said agitator comprising:
- an agitator vessel having an interior;
- an agitator shaft extending into the interior of the agitator vessel to thereby define an axis;
- an agitating propeller mounted to the agitator shaft within the agitator vessel for axially moving a liquid in the agitator vessel in a conveying direction;
- and
- a gas injection device, rotating conjointly with the agitator shaft and positioned at an axial distance downstream of the agitating propeller in the conveying direction of the liquid, for injecting gas into the interior of the agitator vessel.
