Exhaust air purification device and method of purifying exhaust air in a livestock stable

1. An exhaust air purification device for a livestock stable comprising:

at least one exhaust air scrubber having a filter body that can be wetted with a scrubbing liquid or that can absorb a scrubbing liquid; and

a scrubbing liquid container holding a scrubbing liquid, wherein the at least one exhaust air scrubber is arranged on a moving device, the moving device being designed and arranged to immerse the at least one exhaust air scrubber completely or partially into the scrubbing liquid in the scrubbing liquid container,

wherein the at least one exhaust air scrubber comprises a plurality of scrubbing liquid reservoirs that are arranged and designed in such a way that they absorb scrubbing liquid from the scrubbing liquid container and release the scrubbing liquid in the direction of the filter body.

2. An exhaust air purification device according claim 1 , further comprising a plurality of exhaust air scrubbers arranged on a moving device, the moving device designed and arranged to immerse the exhaust air scrubbers completely or partially consecutively into the scrubbing liquid in the scrubbing liquid container.

3. An exhaust air purification device according to claim 1 , wherein the moving device is designed and arranged to move the exhaust air scrubber along a closed movement path.

4. An exhaust air purification device according to claim 3 , wherein the closed movement path includes any of a circular, elliptical, or racetrack-shaped movement path.

5. An exhaust air purification device according claim 1 , wherein the moving device is designed and arranged to immerse the exhaust air scrubber downward into the scrubbing liquid in a vertical direction.

6. An exhaust air purification device according to claim 3 , wherein the closed movement path includes a horizontal movement portion within which the at least one exhaust air scrubber is immersed in the scrubbing liquid.

7. An exhaust air purification device according to claim 1 , wherein the moving device comprises any of a drum, roller, ascending conveyor, elevator, conveyor belt, or longitudinal conveying device.

8. An exhaust air purification device according to claim 1 , wherein the moving device comprises a drive unit, wherein such drive unit is designed to drive the moving device in an operating direction.

9. An exhaust air purification device according to claim 8 , wherein the drive unit comprises any of a rotary drive unit or ratchet drive unit.

10. An exhaust air purification device according to claim 6 , wherein exhaust air flows through the exhaust air purification device in a flow direction, and the flow direction of the exhaust air through the at least one exhaust air scrubber is substantially co-directional to the horizontal movement portion of the movement path of the at least one exhaust air scrubber through the scrubbing liquid when the moving device is driven in an operating direction.

11. An exhaust air purification device according to claim 8 , wherein the drive unit is designed to drive the moving device in either of the operating direction or a cleaning direction, with the cleaning direction being opposite of the operating direction.

12. An exhaust air purification device according to claim 1 , further comprising a housing with an air intake and air outlet and a flow path of exhaust air from the air intake to the air outlet, wherein the exhaust air scrubbers are arranged on the moving device so that the exhaust air along the flow path passes through at least one filter body.

13. An exhaust air purification device according to claim 12 , wherein the exhaust air scrubbers are arranged on the moving device so that the exhaust air along the flow path passes through at least two filter bodies that are not arranged next to each other along the movement path.
