A spray nozzle that includes a nozzle body defining a first surface, a cap defining a second surface able to define an annular nozzle opening therebetween, and a turbine having a plurality of radially extending fins circumferentially positioned about the nozzle opening for directing the flow of fluid exiting the nozzle opening. The turbine is rotatably connected to the cap such that the nozzle opening is free of any portion of the turbine. The spray nozzle further includes a grinding member.

A fluid distributing apparatus is disclosed. The fluid distributing apparatus includes an orifice housing defining a first surface, a deflector plate defining a second surface spaced apart from the first surface to define an annular nozzle opening therebetween, and a turbine located between the first and second surfaces and freely rotatable between the first and second surfaces. The turbine has a plurality of radially extending fins each having leading edge, a trailing edge, and a radial surface for directing the flow of fluid exiting the nozzle opening. At least a first one of the fins has a vane extending at an angle relative to the radial surface so as to redirect the flow of fluid passing along the radial surface of the fin.

Direct forced draft fluid cooler/closed loop cooling towers and cooling towers are provided with fans at the bottom of the unit, and a plurality of layers of water collection troughs or channels above the fans to capture water droplets sprayed downwardly from the top of the device through a heat exchanger or fill media above the collection troughs. In one embodiment the collection troughs supply the collected water to one or more gutters inside the housing which lead the water to an external collection tank from which the water is recirculated through the system.

A fluid distributing apparatus provides a fountain-type distributor which effects substantially uniform radial distribution of fluid across a spray pattern. A fixed deflector is provided for deflecting the spray pattern into a non-circular pattern, and in a preferred case into a rectangular pattern. The distributor is particularly suited for use in industrial cooling towers to increase the efficiency of the cooling towers by increasing the uniformity of water distribution across the fill material of the cooling tower.

A direct forced counterflow cooling tower apparatus includes concrete side walls having L-shaped troughs located at the lower ends thereof. The cooling tower includes a liquid distribution system, fill material located below the liquid distribution system, a drainage collection system located below the fill material and a fan located below the drainage collection system. Liquid is supplied to the tower and is distributed on top of the fill material. The liquid will pass downward therethrough and will be collected by the drainage collection system. The drainage collection system will communicate the liquid to the troughs located at the lower end of the longitudinal side walls. A modular cooling tower construction includes the cooling tower apparatus in combination with at least one additional cooling tower apparatus. The first and at least one additional cooling tower apparatus are aligned longitudinally in series so that the first troughs of the first and at least one additional cooling tower apparatus form a first substantially continuous liquid passageway and so that the second troughs of the first and the at least one additional cooling tower apparatus form a second substantially continuous liquid passageway. The liquid received in the first and second continuous liquid passageways exit the modular cooling tower construction and is dumped in a reservoir.

A direct forced draft counterflow water cooling tower module includes an integral one-piece frame and basin preferably constructed from molded fiberglass. The cooling tower includes a liquid distribution system, fill material located below the liquid distribution system, a drainage collection system located below the fill material, and at least one fan located below the drainage collection system. The fan blows cooling air directly upward through the drainage collection system and then through the fill material.
