Abstract

A liquid collection trough assembly for a cooling tower, condenser or dephlegmator includes a plurality of elongate troughs and associated inclined capture plates arranged to receive liquid on a front face thereof and direct the liquid into an associated elongate trough. Each capture plate has a generally upright deflection plate extending downwards from an upper region on its rear face so as to be capable of receiving liquid droplets contacting it and directing such liquid into or onto an adjacent trough or capture plate, in use. The deflection plate extends downwards to terminate in a bottom edge that is located downwards of the upper region of the capture plate and spaced rearwards of the rear face of an inclined portion of the capture plate.

First claim

The invention claimed is:

1. A liquid collection trough assembly comprising a plurality of elongate troughs and associated inclined capture plates wherein each capture plate is arranged to receive liquid contacting same on a front face thereof and direct the liquid into an associated elongate trough, the liquid collection trough assembly wherein each capture plate has a generally upright deflection plate extending downwards from an upper region thereof on its rear face so as to be capable of receiving liquid droplets contacting it and directing such liquid into or onto an adjacent trough or capture plate, in use, wherein the deflection plate extends downwards to terminate in a bottom edge that is located downwards of said upper region of the capture plate and spaced rearwards of the rear face of an inclined portion of the capture plate and wherein a top edge region of each capture plate and any superimposed deflection plate are vertically extended or inwardly curved towards the face of the capture plate in a manner tending to redirect air passing in an inclined direction between adjacent capture plates to a more vertically extending direction.

2. A liquid collection trough assembly as claimed in claim 1 in which the troughs and associated inclined capture plates are spaced apart such that an upper edge of each of the capture plates is located over a lower edge region of an adjacent capture plate to define inclined flow paths for air between the capture plates.

3. A liquid collection trough assembly as claimed in claim 1 in which each capture plate is formed as an upward extension of one wall of the trough.

4. A liquid collection trough assembly as claimed in claim 1 in which a deflection plate is attached along an upper edge of an associated capture plate.

5. A liquid collection trough assembly as claimed in claim 1 in which the water collection troughs are arranged all in the same horizontal plane.

6. A liquid collection trough assembly as claimed in claim 1 in which each elongate trough is open at either or each end to allow for drainage of liquid collected therein into manifolds or other collection ducts.

7. A liquid collection trough assembly as claimed in claim 1 in which the collection trough assembly is installed beneath a fill or tube bundle of a cooling tower, condenser or dephlegmator.

8. A liquid collection trough assembly comprising a plurality of elongate troughs and associated inclined capture plates wherein each capture plate is arranged to receive liquid contacting same on a front face thereof and direct the liquid into an associated elongate trough, the liquid collection trough assembly wherein each capture plate has a generally upright deflection plate extending downwards from an upper region thereof on its rear face so as to be capable of receiving liquid droplets contacting it and directing such liquid into or onto an adjacent trough or capture plate, in use, wherein the deflection plate extends downwards to terminate in a bottom edge that is located downwards of said upper region of the capture plate and spaced rearwards of the rear face of an inclined portion of the capture plate, wherein the water collection troughs are arranged at regularly staggered vertical positions in a plurality of vertically spaced horizontal planes.
