Abstract

A baffle is disclosed which comprises a plurality of substantially S-shaped baffle members and a frame configured to hold the baffle members substantially parallel to each other. The baffle is configured to separate one or more entrained substances from an air stream.

Claims (70)

1. A separation cartridge comprising:

a baffle including

a plurality of substantially S-shaped baffle members; and

a frame configured to hold the baffle members substantially parallel to each other; and

another separation medium positioned parallel to the baffle;

wherein the separation cartridge is configured to separate an oleo substance from an air stream in a kitchen hood system.

2. The separation cartridge of claim 1 , wherein the another separation medium includes a bed of particles.

3. The separation cartridge of claim 1 , wherein the plurality of baffle members form a plurality of channels, each channel having a single entry opening and a single exit opening.

4. The separation cartridge of claim 1 , wherein the separation cartridge includes a mesh filter.

5. The separation cartridge of claim 1 , wherein the plurality of baffle members have rounded edges.

6. A separation cartridge comprising:

a baffle including a plurality of substantially S-shaped baffle members positioned in a substantially parallel relationship to each other; and

another separation medium;

wherein the separation cartridge is configured to separate an oleo substance from an air stream in a kitchen hood system;

wherein the separation cartridge is configured so that the air stream passes through the baffle and the another separation medium in series.

7. The separation cartridge of claim 6 , wherein the separation cartridge is configured to be mounted in a kitchen hood.

8. The separation cartridge of claim 6 , wherein the plurality of baffle members have rounded edges.

9. The separation cartridge of claim 6 , wherein the another separation medium includes a mesh filter.

10. The separation cartridge of claim 6 , wherein the baffle and the another separation medium are positioned immediately adjacent to or in contact with each other.

11. A baffle for removing an oleo substance from an air stream in a kitchen hood system comprising:

a plurality of baffle members positioned substantially parallel to each other and extending between a first side of the baffle and a second side of the baffle, the plurality of baffle members defining a plurality of channels each comprising a single entry opening and a single exit opening, the plurality of baffle members having rounded edges;

wherein the minimum amount the oleo substance must be deflected to pass through each of the plurality of channels is at least approximately 180 degrees; and

wherein the baffle is configured to separate the oleo substance from the air stream in the kitchen hood system.

12. The baffle of claim 11 , wherein the baffle members are substantially S-shaped.

13. The baffle of claim 11 , wherein the minimum amount the substance must be deflected to pass through each of the plurality of channels is at least approximately 200 degrees.

14. A separation cartridge comprising the baffle recited in claim 11 and a bed of particles.

15. A separation cartridge comprising:

a baffle including a plurality of baffle members each of which has rounded edges; and

another separation medium;

wherein the separation cartridge is configured to separate an oleo substance from an air stream in a kitchen hood system.

16. The separation cartridge of claim 15 , wherein the radius of the rounded edges is at least approximately 1.5 times the thickness of the baffle members.

17. The separation cartridge of claim 15 , wherein the another separation medium includes a bed of particles.

18. The separation cartridge of claim 15 , wherein the roundd edges are made by folding the baffle members over on themselves.

19. The separation cartridge of claim 15 , wherein the baffle and the another separation medium are positioned immediately adjacent to or in contact with each other.

20. A baffle comprising a plurality of substantially S-shaped baffle members each of which has rounded edges, the baffle being configured to separate an oleo substance from an air stream in a kitchen hood system.

21. The baffle of claim 20 , wherein the baffle is configured so that the minimum amount a substance must be deflected to pass through the baffle is at least approximately 180 degrees.

22. The baffle of claim 20 , wherein the plurality of baffle members define a plurality of channels each of which has a single entry opening and a single exit opening.

23. A separation cartridge comprising the baffle recited in claim 20 and a bed of particles.

24. A separation cartridge comprising:

a baffle including a plurality of substantially S-shaped baffle members;

a mesh filter; and

a bed of particles;

wherein the separation cartridge is configured to separate an oleo substance from an air stream in a kitchen hood system.

25. The separation cartridge of claim 24 , wherein the mesh filter is positioned between the baffle and the bed of particles.

26. A baffle comprising:

a plurality of baffle members defining a plurality of channels, each channel being configured to deflect an air stream in a kitchen hood system as the air stream passes through the channel;

a frame configured to hold the baffle members in a substantially parallel relationship to each other; and

a plurality of particles positioned inside the channels.

27. The baffle of claim 26 , wherein the particles include inorganic particles.

28. The baffle of claim 26 , wherein the particles are porous.

29. A kitchen hood comprising:

a baffle including a plurality of baffle members each of which has rounded edges, the plurality of baffle members being substantially S-shaped; and

a bed of particles;

wherein the baffle and the bed of particles are positioned in the kitchen hood.

30. The kitchen hood of claim 29 , comprising a separation cartridge that includes the baffle and the bed of particles, the separation cartridge being mounted in the kitchen hood.

31. The kitchen hood of claim 29 , comprising a mesh filter positioned in the kitchen hood.
