Arrangement for recooling cooling water

Abstract

The arrangement (1) comprises distributor pipes (6) that are supported by horizontal bars (3) and have downwardly directed spray nozzles (16) and mist collectors (8). The bars (3) are provided with bearing points (5) that are open toward the top and extend across the entire lengths thereof for the integration of the distributor pipes (6). Two consecutive bearing points (5) each in the longitudinal direction of the bars (3) are separated from each other by means of a support (7) for the mist collectors (8). Beneath the bars (3), multi-layer dripping installations (13) are provided, against which cooling air blows.

The distributor pipes form jointly with the mist collectors, provided above the distributor pipes, and the dripping installations, arranged below the distributor pipe and configured in the shape of, for example, thin-walled sheets or ...

AI Technical Summary

Benefits of technology

[0008]The invention is based on the object to provide an arrangement for recooling cooling water, which ensures simpler assembly of the distributor pipes and significantly reduces labor when the distributor pipes require repair later.

[0011]The invention thus enables easy installation of the distributor pipes, even at a greater number, from above into the bearing points. Coupling of the distributor pipes can be implemented while the distributor pipes are positioned in the bearing points. There is no longer a need for special auxiliary tools in order to install the distributor pipes because they are arranged horizontally and not suspended.

[0016]According to another advantageous feature of the invention, rails are provided atop the supports in longitudinal direction of the bars, with the rails having pocket-like receptacles for the mist collectors. Therefore, the mist collectors are placed, not directly on the supports, but on the rails extending on atop the supports. The receptacles atop the supports provide a reliable lateral guidance of the rails. The rails for receiving the mist collectors may also be a component of the mist collectors themselves. A retaining rail is hereby attached virtually to the top end or end face of the mist collector stacks to longitudinally support the mist collectors above the bars.

[0018]Taking into account that the distributor pipes are located in the bearing points of the bars, it is provided according to another feature of the invention to distance the spray nozzles from the distributor pipes by vertically extending bridging pipes for shortening the distance between the spray nozzles and the dripping installations. The bridging pipes have then a length which corresponds approximately to the vertical thickness of the bars underneath the bearing points.

Problems solved by technology

Considering the cross sectional dimensions of a cooling tower and the need to hold the distributor pipes at several suspension points, the assembly becomes very labor-intensive.

Moreover, the distributor pipes can only be installed consecutively because of their limited length so that the provision of a plurality of coupling sites is required.

This requires to provisionally secure them first and then to render the securement ineffective while removing the individual distributor pipes upwards between the bars.

As a result, the distributor pipes need to be sized short, thereby still further increasing the complexity of disassembly and assembly with respect to the couplings between two distributor pipes.

This means that comparably short distributor pipes are used which thus require as many coupling sites.

This, too, complicates assembly and increases costs.
