Abstract

An apparatus (100) for mixing multiphase flowing particles. The apparatus (100) comprises a conduit (100a) adapted to channelize the multiphase flowing particles. At least one flow diverter (101) is positioned in the conduit (100a), which is adapted to divert the flow of multiphase flowing particles into a plurality of flow streams. Further, at least one flow element (102) is disposed in the conduit (100a) along at least one of the plurality of flow streams, which is configured to inject fluid onto the plurality of flow streams at a velocity greater than the velocity of the plurality of flow streams. This induces a swirling flow of at least one of the plurality of flow streams, thereby facilitating mixing of the multiphase flowing particles in the conduit (100a).

First claim

We claim:

1. An apparatus for mixing multiphase flowing particles, the apparatus comprising:
a conduit adapted to channelize the multiphase flowing particles;
at least one flow diverter positioned in the conduit, wherein the at least one flow diverter is adapted to divert flow of the multiphase flowing particles into a plurality of flow streams; and
a plurality of flow elements disposed on either sides of the conduit along at least one of the plurality of flow streams, an outlet of each of the plurality of flow elements provisioned on one of the sides of the conduit is oriented diagonally opposite to the outlet of corresponding at least one of the plurality of the flow elements provisioned on other side of the conduit, wherein the plurality of flow elements are configured to inject fluid onto the plurality of flow streams at a velocity greater than the velocity of the plurality of flow streams, such that, the fluid injected, through the diagonally opposite oriented outlets of the respective plurality of flow elements to have a diagonally intersecting fluid stream, to induce a swirling flow of at least one of the plurality of flow streams, thereby facilitating mixing of the multiphase flowing particles in the conduit.

2. The apparatus as claimed in claim 1 , wherein the at least one flow diverter is positioned at the bottom of the conduit.

3. The apparatus as claimed in claim 2 , wherein the shape of the at least one flow diverter is at least one of triangular, rhombic and hexagonal.

4. The method as claimed in claim 3 , wherein the swirling flow of at least one of the plurality of flow streams is induced along the length of the conduit.

5. The apparatus as claimed in claim 1 , wherein the conduit comprises an inlet side and an outlet side.

6. The apparatus as claimed in claim 1 , wherein the at least one flow diverter is positioned proximal to inlet side of the conduit.

7. The apparatus as claimed in claim 6 , wherein the plurality of flow elements are at least one of nozzles, orifices and jet impingers.

8. The apparatus as claimed in claim 6 , wherein the plurality of flow elements are positioned at a predetermined angle to the longitudinal axis of the conduit, to induce the swirling flow of at least one of the plurality of flow streams.

9. An apparatus for culturing photosynthetic organisms comprising an apparatus for mixing multiphase flowing particles as claimed in claim 1 .

10. A method for mixing multiphase flowing particles, the method comprising:
channelizing the multiphase flowing particles through a conduit;
diverting flow of the multiphase flowing particles into a plurality of flow streams by at least one flow diverter positioned in the conduit; and
injecting fluid onto the plurality of flow streams at a velocity greater than the velocity of the plurality of flow streams, wherein an outlet of each of a plurality of flow elements provisioned on one of the sides of the conduit is oriented diagonally opposite to the outlet of corresponding at least one of the plurality of the flow elements provisioned on other side of the conduit such that, the fluid injected, through diagonally opposite oriented outlets of the respective plurality of flow elements have a diagonally intersecting fluid stream, to induce a swirling flow of at least one of the plurality of flow streams, thereby facilitating mixing of the multiphase flowing particles in the conduit.
