Abstract

A catalyst scrubber apparatus includes a housing having an internal space; a catalyst carrier disposed in the internal space of the housing; and a plurality of nozzles installed in the housing and disposed above the catalyst carrier, wherein at least two of the plurality of nozzles are configured to receive and spray fluid therethrough, the at least two of the plurality of nozzles are shaped and dimensioned to diffuse the fluid sprayed into the internal space of the housing.

First claim

What is claimed is:

1 . A catalyst scrubber apparatus comprising:
a housing having an internal space; a catalyst carrier disposed in the internal space of the housing; and a plurality of nozzles installed in the housing and disposed above the catalyst carrier, wherein at least two of the plurality of nozzles are configured to receive and spray fluid therethrough, the at least two of the plurality of nozzles are shaped and dimensioned to diffuse the fluid sprayed into the internal space of the housing.

2 . The catalyst scrubber apparatus of claim 1 , wherein a cross-sectional area of an upper end of each of the at least two nozzles is smaller than a cross-sectional area of a lower end of each of the at least two nozzles.

3 . The catalyst scrubber apparatus of claim 2 , wherein the nozzle has an inclined surface on an internal surface, and an inclination angle of the inclined surface ranges from about 8° to about 10°.

4 . The catalyst scrubber apparatus of claim 1 , wherein, when a diameter of the catalyst carrier is β, a distance between central axes of the at least two nozzles ranges from about 0.4β to about 0.6β.

5 . The catalyst scrubber apparatus of claim 4 , wherein a distance from a central axis of an upper wall of the housing to a central axis of the nozzle ranges from 0.2β to 0.3β.

6 . The catalyst scrubber apparatus of claim 5 , wherein the at least two nozzles are symmetrical to the central axis of the upper wall of the housing.

7 . The catalyst scrubber apparatus of claim 4 , wherein at least two of the nozzles are arranged along a straight line passing through a central axis of an upper wall of the housing.

8 . The catalyst scrubber apparatus of claim 1 , wherein the internal space of the housing disposed above the catalyst carrier has a funnel shape narrowing down in width from an upper end to a lower end.

9 . The catalyst scrubber apparatus of claim 1 , wherein the at least two nozzles are connected to a connecting member installed on a cover member provided in the housing.

10 . The catalyst scrubber apparatus of claim 9 , wherein a supply pipe is installed in the cover member to supply air to at least two of the two nozzles.

11 . The catalyst scrubber apparatus of claim 1 , wherein at least two of the nozzles have an inclined surface at an end of an internal surface, and an inclination angle of the inclined surface ranges from about 8° to about 10°.

12 . The catalyst scrubber apparatus of claim 11 , wherein, when a diameter of the catalyst carrier is β, a distance between centers of the ends of at least two of the nozzles range from about 0.4β to about 0.6β.

13 . A catalyst scrubber apparatus comprising:
a housing having an internal space; a catalyst carrier disposed in the internal space of the housing; and at least two nozzles installed in the housing and disposed above the catalyst carrier, wherein the nozzle has an inclined surface on an internal surface.

14 . The catalyst scrubber apparatus of claim 13 , wherein the inclination angle of the inclined surface ranges from about 8° to about 10°.

15 . The catalyst scrubber apparatus of claim 13 , wherein, when a diameter of the catalyst carrier is β, a distance between central axes of the at least two nozzles ranges from about 0.4β to about 0.6β.

16 . The catalyst scrubber apparatus of claim 15 , wherein a distance from a central axis of an upper wall of the housing to a central axis of the nozzle ranges from 0.2β to 0.3β.

17 . The catalyst scrubber apparatus of claim 13 , wherein the at least two nozzles are symmetrical to the central axis of the upper wall of the housing.

18 . A catalyst scrubber apparatus comprising:
a housing having an internal space; a catalyst carrier disposed in the internal space of the housing, wherein the catalyst carrier uses a catalyst to solidify a chemical gas; and at least two nozzles installed in the housing and disposed above the catalyst carrier, wherein the nozzle has an inclined surface on an internal surface, and wherein the inclination angle of the inclined surface ranges from about 8° to about 10°.

19 . The catalyst scrubber apparatus of claim 18 , wherein, when a diameter of the catalyst carrier is β, a distance between central axes of the at least two nozzles range from about 0.4β to about 0.6β.

20 . The catalyst scrubber apparatus of claim 15 , wherein a distance from a central axis of an upper wall of the housing to a central axis of the nozzle ranges from 0.2β to 0.3β.
