Abstract: A collection system for use in cooling towers is disclosed. The collection system includes a plurality of spaced collection troughs with a pre-collector thereabove disposed between the fill material in the cooling tower and the collection troughs. The pre-collector includes a plurality of corrugated sheets positioned laterally and transversely adjacent one another to substantially fill the space between the collection troughs and the fill material. Water falling through the cooling tower will fall on the corrugations and will be directed by the corrugations into vertical discharge drains defined by the corrugated sheets. The vertical discharge drains will direct liquid falling onto the sloped flow surfaces defined by the corrugated sheets into collection troughs therebelow.

Abstract: A vertical fluid dynamic cooling tower includes a shell which ha s a horizontal tubular injection element disposed inside. A pressurized heat liquid is pumped into the tubular element and ejected out upwardly through spaced nozzles disposed on the top of the tubular element to create a continuous screen of dispersed liquid flow. A diffuser is disposed within the shell and above the injection tubular element to enable the ejected heated fluid to convert pressure to kinetic energy, to induce negative pressure at a lower section and to generate a cooling effect for the heated fluid. A mist eliminator is disposed at the top of the shell to separate fluid from the air. An air exhaust outlet is located at the top of the shell for discharging heated air. The condensed and separated fluid falls down into a heat dissipating device located at the lower portion of the shell for a second heat exchange process. The cooled fluid then passes through a silencer and drops into a drip tray to be pumped for reuse.

Abstract: A modular cooling tower apparatus is formed from a plurality of pultruded fiberglass structural members. Four hollow beams are joined together to form a combined liquid basin and support frame structure. A dual-layer drainage collection system rests upon the hollow beams and collects liquid and drains it into the hollow beams. A five-foot-thick body of fill material rests upon the drainage collection system. The overall height of the assembly from the bottom of the basin to the top of the unit is less than eleven feet thus allowing transportation on conventional trucking equipment.

Abstract: A direct forced draft counterflow cooling tower apparatus is provided with a dual layer drainage collection system. Preferably, the lower layer of collection plates is formed of hollow plates having interiors which receive the warm water collected on the upper layer of plates. This provides a thermal charging or warming of the lower plates so as to prevent icing of the lower layer of plates of the drainage collection system during cold wintertime operating conditions.

Abstract: Low cost sealing drainboard supports adapted for use between adjacent drift eliminator sections in water cooling towers are provided which can be readily installed in the field without the necessity of custom fabrication of structural components, and which give improved drainage characteristics in the form of relatively large, concentrated streams of eliminated water resistant to reentrainment. The preferred supports are unitary, preformed synthetic resin bodies presenting an elongated, eliminator section-receiving channel together with a depending inner sealing wall and a oblique, downwardly and outwardly extending drainage tray. The tray is preformed to present a series of generally V-shaped in plane, increasing depth drainage passageways serving to collect and concentrate eliminated water into relatively large streams resistant to reentrainment in the air currents passing through the tower.

Abstract: A tower structure for gas-liquid interaction produces rolling turbulence in a gas flow path that has low pressure drop. The structure includes a spaced plurality of vertically disposed wall members in an upwardly directed flow path, a staggered array of horizontally extending deflectors protruding from facing wall members, forming a series of converging and diverging chamber portions in which the gas flows generally perpendicular to the deflectors. Rolling turbulence is produced between apexes of the deflectors and the facing wall portions, the gas flow being offset toward opposite wall members at succeeding apexes. In one configuration, a liquid is transported within the gas flow, in contact with the gas. In anothor configuration, the liquid is separate from the gas. In a further configuration, two liquid paths are provided, one in contact with the gas, one separate from the gas.

Abstract: In a wet type or wet/dry type cooling tower, water discharged from water distributing means after its passage cooling air heat exchanger is intercepted by an array of parallel water guiding plates. Each guiding plate has a sloping upper part which covers the gap between opposite plates and an upright lower part defining a substantially horizontal transition region with the upper part. A plurality of inclined channel like embossments is formed in the upright lower part. The embossments extend one above the other between a lateral edge of the upright lower part and the transition region. At least one water collecting channel extends in transverse direction along the lateral edges of the upright lower part to collect water discharged from the inclined embossments and transfer the collected water to a recirculation device.

Abstract: A drainage collection system for use in an evaporative cooling tower is disposed transversely within a cooling tower below a gas/liquid heat exchanging contact body to receive liquid gravitating therefrom and to collect the same. The drainage collection system includes a plurality of liquid collection plates which are arranged in parallel and inclined from the vertical. Each of the plates includes an upper and a lower end portion with the upper end portion of each overlapping the lower end portion of a respectively adjacent plate. Each plate is shaped over its central portion to form substantially planar upper and lower sections. The lower section is inclined less from the vertical than the upper section. The lower end portion of each of the plates is shaped to form primary and secondary collecting channels extending substantially across the width of the plate for collecting liquid directed thereto by the plate.
