US4499034A – Vortex-augmented Cooling Tower-windmill Combination – Google Patents

U.S. Pat. No. 4,031,173 issued to Paul Rogers discloses a tower having an arrangement of blade-like surfaces mounted on the exterior of the tower for rotation about the tower in a horizontal plane in response to wind movement. The tower may be filled with rock fragments or may include a lattice-work matrix through which the air current passes to evaporate and cool the water which is continually sprayed on the rock or matrix surfaces.

NEUROCIRUGÍA-PASIÓN - YouTube A cooling tower is judged by its effectiveness in cooling a given water flow. On the other hand, in the tower 33 of FIG. This research involves methods of reducing the windmill back pressure. Since the pressure drop for air moving upward past water droplets is less than the typical cooling tower in which air flows through the beam matrix-type fill material, greater air velocity and mass flow is possible for this type of water-air heat transfer. Still another object is to provide tower means for confining and upwardly directing currents of atmospheric air by means of which effluent water may be cooled and power may be generated by conventional windmills. By arranging each of the air passages 12 to direct air in symmetrical helical paths, the currents of air leaving the respective outlets 26 join together at the base of the tower 10 to generate a single helical upwardly directed flow of air within the tower, as indicated by the arrows in FIG.

Since the flow’s circulation upon leaving the cooling tower is fixed, the plume slowly develops because the flow vorticity resists atmospheric diffusive action. The difference in axial exit velocities for the vortex and non-vortex cases would suggest a 26% increase for the vortex case. If horizontally rotating windmills are placed at the ground level in the plane of the tower wall the water droplets in the tower cross-sectional area would not be uniformly distributed and poor water cooling would result.

To increase this velocity, the fill material in a typical cooling tower is not used and the water to be cooled is sprayed into the tower. A further object is to provide a cooling tower having an unobstructed vortex air flow pattern in the tower to increase the tower efficiency and including wind turbine power generating means operated by the air flow thus produced. Another object is to provide a water cooling tower which includes wind turbine power generating means located outside of the tower itself to avoid interference with either the flow of air in the tower or the interactive pattern of contact between water to be cooled and the cooling air.

The result was that a minimal increase in power output was accompanied by excessive costs in additional wind turbine support structures. The result is to increase the effective height of tower 33 beyond its actual physical elevation and since the draft in the tower is a function of height the benefit of increased efficiency in the generation of power by wind turbine devices 12 is increased without the expense of additional construction costs. DETAILED DESCRIPTION OF THE INVENTION In the drawings, a large vertical cooling tower is indicated generally by numeral 10, said tower being provided with omnidirectional atmospheric air inlet means at its base, indicated generally by numeral 11, said air inlet means including wind turbine actuated power generating means, indicated generally by numeral 12. Enantyum dolor muscular . Appropriate nozzle means, indicated generally by numeral 13, is provided for introducing water into the interior of the tower to be cooled by the flow of air from inlet means 11 upwardly to the outlet opening 14 at the top of the tower.

U.S. Pat. No. 4,070,131, issued to James T. Yen discloses two forms of towers in which a vortex core air flow with a wind turbine rotating in a horizontal plane located at the base of the tower. 1. Studies have further shown that the horizontal orientation of the air passages should be such that the body of air entering from each of the passages should be directed at an angle α no greater than 30° with respect to a radius of the tower, as can be seen in FIG. It should also be mentioned that no specific provision for cooling water is disclosed in this patent. FIELD OF THE INVENTION The present invention relates to cooling towers by means of which wind forces are harnessed to bring ambient air into intimate contact with effluent water discharged at high temperature from a production facility and, as an ancillary benefit, to generate power, to cooling of the effluent water being required to permit its return to the natural stream, or river, from which it was obtained without impairing the ecological balance.

Increased power production results from increasing either the blade diameter or the air velocity. The specific volume diffference in Equation 3 are equivalent to the Boussinesq approximation discussed in H. Tennekes and J. L.

Yet another object is to provide a wind operated water cooling and power generating tower having air inlet means at its base arranged to introduce atmospheric air into the base in a helical direction to generate a solid core vortex flow air discharge path in the tower. Within each of the passages 15 a wind operated power generating means, such as a windmill 17 is mounted for customary rotation about a horizontal axis and, in order to confine the air flow for maximum effectiveness in driving the windmill, the inlet end 16 is preferably circular in outline and may be inwardly constricted, as at 18, to provide a venturi effect. The omnidirectional air inlet means 11 preferably comprises a series of helically directed horizontally extending similar passages 15 disposed about the entire exterior periphery at the base of tower 10. The inlet ends 16 of each of the passages are located radially outwardly of the tower, so that at any given time these inlets will collect a flow of atmospheric air, regardless of the wind direction.

To avoid this problem the windmills are located at a distance outwardly from the base of the tower and their exhausts are directed by means of horizontal passages to the tower base. First, standard windmills can be used because the blades are perpendicular to the ground. First, the vortex generates larger air velocities which increases the heat transfer between the ambient air and water.

Third, the windmills are physically located to avoid interfering with the heat transfer processes between the water addition and ground levels. Generally, when the generation of power as an ancillary benefit is considered, an unimpeded air draft in the tower is required and water is supplied by nozzles arranged around the interior wall of the tower near the base to minimize the amount of water lost as evaporated vapor. It is apparent that for the tower to be able to cool effectively and operate a windmill in the exit plane, the air flow exit velocity must be increased.

The larger the tower diameter, the larger the air flow. Second, relatively simple installation is possible when compared to the windmill configuration in which turbines rotating about a vertical axis are placed in the tower itself. 2 it can be seen that, it there are nine air inlet passages disposed about the base of the tower 10, regardless of the direction from which the wind is blowing, there will always be at least three, and possibly as many as four, of the inlets 16 which are positioned to capture portions of the blowing air and to rotate the windmills 12 positioned directly downstream from those inlets to generate electricity in varying amounts by the devices 18 connected to them. Nine windmills with 24 foot diameter blades were placed around the tower base. However, it was found that the blades interferred with the tower’s natural drafting ability especially when the velocity of the air draft at the exit plane was in the range of 12-15 ft/sec or less.

Two percent of the available 28,000 lbm/sec air flow was reserved for boundary layer control (see FIG. For the maximum air flow of 28,000 lbm/sec, the 40 ft/sec axial axit velocity indicated an approximate viscous vortex core of 60 ft diameter.
