Abstract

A rotor for rotating packed bed units (RPBs) is described. The rotor comprises a first plate and a second plate. The rotor further comprises a plurality of sets of rings concentrically interposed between the first plate and the second plate. Each set of rings comprises a plurality of rings are arranged cylindrically. Further, each ring comprises a plurality of packing elements. The rotor further comprises at least one metallic ring interposed between the plurality of sets of rings.

First claim

We claim:

1. A rotor for rotating packed bed (RPB) units, the rotor comprising:
a first plate;
a second plate, wherein the first plate and the second plate comprise a plurality of grooves;
a plurality of metal rings concentrically mounted on the plurality of grooves;
a plurality of sets of rings mounted on the plurality of metal rings, wherein each ring of the plurality of sets of rings comprises a plurality of packing elements;
a fastener to fasten the first plate, the second plate, the plurality of sets of rings, and the plurality of metal rings, wherein the plurality of sets of rings, the first plate, the second plate, and the plurality of metal rings are stacked along the fastener;
a gas nozzle inside the rotor vessel to feed the gases into the rotor vessel; and
a gas impingement plate including a plurality of holes mounted at an exit of a gas nozzle for distributing gas in the rotor vessel.

2. The rotor as claimed in claim 1 , wherein one of the first plate and the second plate is coupled to a shaft to rotate the rotor, wherein an outer surface of the shaft comprises a plurality of sequential steps tapered along a length of the outer surface.

3. A rotating packed bed (RPB) unit comprising:
a rotor vessel comprising:
a rotor, wherein the rotor comprises:
a first plate;
a second plate, wherein the first plate and the second plate comprise a plurality of grooves;
a plurality of metal rings concentrically mounted on the plurality of grooves;
a plurality of set of rings mounted on the plurality of metal rings, wherein each ring of the plurality of set of rings comprises a plurality of packing elements;
a fastener to fasten the first plate, the second plate, the plurality of metallic rings, and the plurality of metallic ring, wherein the plurality of set of rings, the first plate, the second plate, and the plurality of metallic rings are stacked along the fastener;
a gas nozzle inside the rotor vessel to feed the gases into the rotor vessel; and
a gas impingement plate including a plurality of holes mounted at an exit of a gas nozzle for distributing gas in the rotor vessel;

a liquid inlet and gas outlet pipe assembly coupled to the rotor, the liquid inlet and
gas outlet pipe assembly comprising:
a gas outlet pipe to affect expulsion of the gas from the rotor; and
a liquid inlet pipe housing the gas outlet pipe to form a region to affect inflow of liquid into the rotor; and

a shaft coupled to one of the first plate and the second plate of the rotor to rotate the rotor.

4. The RPB unit as claimed in claim 3 , wherein the RPB unit further comprises a bearing housing mounted onto the shaft to counter at least one of a radial load and an axial load affected by the rotor, the bearing housing comprising:
one or more ball bearings to hold the rotor in a predetermined position; and
one or more seals coupled to the rotor vessel and the shaft to check leakage of air and gas from the rotor vessel.

5. The RPB unit as claimed in claim 4 , wherein the bearing housing is configured to allow circulation of lubricant and cooling water to the one or more ball bearings.

6. The RPB unit as claimed in claim 3 , wherein the liquid inlet pipe is provided with one or more liquid distributor pipes, wherein each of the one or more liquid distributor pipes comprises one or more nozzles to distribute liquid.

7. The RPB unit as claimed in claim 3 , wherein a motor is coupled to the shaft to rotate the shaft.
