Abstract

A recyclable ceramic catalyst filter, a filtering system including the same, and a method of managing the filtering system are provided. The ceramic catalyst filter has a monolithic structure including a first surface which blocks a first material; and a second surface which removes a second material that passed through the first surface, where the second surface is activated and operates as a catalyst layer which removes the second material in response to energy supplied to the second surface.

First claim

What is claimed is:

1. A catalyst filter, the catalyst filter comprising:
a plurality of first grooves in which air is entered; and
a plurality of second grooves from which the air passed the first grooves is discharged and to which energy is provided from a front of the second grooves;
wherein the first grooves and the second grooves extend opposite directions from each other, and
first surfaces form an entire inside surface of the first grooves and second surfaces form an entire inside surface of the second grooves;
bottom surfaces of the first surfaces are disposed between inlets of the second grooves, and
the bottom surfaces of the first surfaces have a configuration that blocks a second material including a volatile organic compound, while side surfaces of the first surfaces have a configuration that passes the second material, wherein a catalyst material layer is between the first surfaces and the second surfaces, the catalyst material layer is a single layer, and the catalyst material layer comprises the first surfaces and the second surfaces, and wherein the second surfaces are activated by the energy.

2. The catalyst filter of claim 1 , wherein the catalyst material layer comprises a porous material layer.

3. The catalyst filter of claim 1 , wherein the first and second surfaces each comprise surfaces that are vertically or horizontally parallel to each other.

4. The catalyst filter of claim 1 , wherein the air entered in the plurality of first grooves comprises a first material and the second material that are harmful and different from each other, and
wherein the first material comprises micro-dust.

5. The catalyst filter of claim 1 , wherein the catalyst material is a photo-catalyst material, and the second surfaces are activated by an optical energy.

6. The catalyst filter of claim 1 , wherein the catalyst material is an electric catalyst material, and the second surfaces are further activated by an electric energy.

7. The catalyst filter of claim 1 , wherein the catalyst material is an ion catalyst material, and the second surfaces are further activated by an ion energy.

8. The catalyst filter of claim 1 , wherein the catalyst material comprises a metal oxide.

9. The catalyst filter of claim 1 , wherein bottom surfaces of the second surfaces are disposed between inlets of the first grooves.

10. The catalyst filter of claim 9 , wherein air permeability of the bottom surfaces of the first surfaces and air permeability of the bottom surfaces of the second surfaces are different from each other.

11. The catalyst filter of claim 9 , wherein a diameter of at least one of the first and second grooves decreases toward the bottom surfaces thereof from the inlets of the at least one first and second grooves.

12. The catalyst filter of claim 1 , wherein a material layer between the first grooves and the second grooves has air permeability and allows the second material to permeate through the material layer.

13. The catalyst filter of claim 1 , wherein the first and second grooves have each a wedge shape.

14. A filtering system comprising:
the catalyst filter of claim 1 ; and
an energy supply device which supplies energy for catalyst activation in the catalyst filter.

15. The filtering system of claim 14 , wherein the energy supply device comprises at least one of an optical energy source, an electric energy source, an ion energy source, and a thermal energy source.

16. A catalyst filter, comprising:
a plurality of first grooves in which air is entered; and
a plurality of second grooves from which the air passed the first grooves is discharged;
wherein the first grooves and the second grooves extend opposite directions from each other,
wherein first surfaces form an entire inside surface of the first grooves and second surfaces form an entire inside surface of the second grooves, where one of the first grooves is surrounded by four first surfaces and one of the first surfaces is surrounded by four first grooves;
a material layer is disposed to include surfaces defining the second grooves, and includes a thermal catalyst material, and
the second surfaces are activated by a thermal energy provided from a front of the second grooves; and
wherein a catalyst material layer is between the first surfaces and the second surfaces, the catalyst material layer is a single layer, and the catalyst material layer comprises the first surfaces and the second surfaces.

17. The catalyst filter of claim 1 , wherein the first surfaces of the plurality of first grooves are connected each other and the second surfaces of the plurality of second grooves are connected each other.

18. The catalyst filter of claim 1 , wherein the plurality of first grooves are arranged in a first direction and a second direction perpendicular to the first direction, and
wherein the plurality of first grooves are separated in the first and second directions.

19. The catalyst filter of claim 1 , wherein areas of the inlets of the plurality of second grooves are the same as or different from areas of inlets of the plurality of first grooves and areas of bottoms of the plurality of the first grooves are the same as or different from areas of bottoms of the plurality of second grooves.
