Description

Hyperbolic cooling tower water recovery system Technical Field The utility model relates to the technical field of cooling tower water recovery, in particular to a hyperbolic cooling tower water recovery system. Background In industrial production, a large amount of waste heat generated in high-temperature process (such as thermal power generation, steel smelting, chemical reaction and the like) is required to be dissipated through a cooling system so as to ensure stable operation of equipment, and besides, a hyperbolic cooling tower is adopted as core cooling equipment in part of urban central heating systems, aeration tanks of sewage treatment plants and the like. The hyperbolic cooling tower is used as a typical natural ventilation cooling tower, and the marked hyperbolic shell structure of the cooling tower drives air in the tower to perform heat and mass exchange with cooling water by using a hot pressing effect formed by air density difference, has the advantages of no mechanical ventilation equipment (or only auxiliary ventilation), low energy consumption, large treatment capacity and the like, and becomes core equipment of a large-scale cooling system. The working principle of the hyperbolic cooling tower is that hot water to be cooled is lifted to the top of the cooling tower through a circulating water pump and uniformly spilled on a filler filled in the tower through a water distribution system, meanwhile, external cold air flows in from an air inlet at the bottom of the cooling tower, air is accelerated to flow upwards under the guidance of a hyperbolic structure of a tower body, hot water fully contacts with the cold air in a gap of the filler to perform efficient heat exchange, and during the period, the cold air absorbs the heat of the hot water, the temperature rises, the water vapor content increases, finally, wet hot air is formed, and the wet hot air is discharged from the top of the tower by the aid of the suction force generated by the tower body, so that the cooling of the hot water is realized. However, this mode of operation exposes a significant disadvantage in terms of water conservation, since the cooling process is highly dependent on the heat exchange of water with air, a large amount of water being lost to the atmosphere by evaporation. Even though means of optimizing water spraying density, improving filler materials and the like are adopted at present, evaporation loss is still a main part of water resource consumption of the hyperbolic cooling tower, and particularly under the high-temperature drought climate condition, the evaporation rate is greatly improved, and the problem of water resource waste is more remarkable. In addition, during the air flow, part of the water droplets can be carried out of the cooling tower with the air flow, causing a non-negligible windage loss. Although devices such as a water collector are arranged, such phenomena are difficult to be stopped. With the increasing severity of global water resource shortage, efficient use of industrial water is a critical issue to be addressed. In this context, acoustic wave-based water conservation techniques are increasingly emerging and evolving. The application of the sound wave technology in the water saving field brings new thought and possibility for solving the problem of water resource waste of the cooling tower. However, at present, how to effectively apply the acoustic wave technology to the hyperbolic cooling tower, so as to actually improve the water-saving effect of the hyperbolic cooling tower, and still the technical problem to be overcome is still urgent in the industry. Disclosure of utility model The utility model aims to provide a hyperbolic cooling tower water recovery system, a condensation structure and an acoustic wave generator are arranged in the hyperbolic cooling tower, and the acoustic wave generated by the acoustic wave generator is utilized to interact with hot and humid air in the tower body, so that the molecular motion state of vapor carried in the hot and humid air is changed under the action of the acoustic wave, the condensation process of the vapor is accelerated, a longitudinally arranged baffle plate is matched with the acoustic wave generator to further promote the condensation effect, water drops condensed under the action of the acoustic wave are attached to the baffle plate and slide along the surface of the baffle plate to be recovered, the water vapor amount discharged out of the tower along with the hot air is greatly reduced, thereby obviously reducing the water evaporation loss of the cooling tower, effectively improving the utilization rate of water resources, and solving the technical problem of how to effectively apply the acoustic wave technology to the hyperbolic cooling tower, and practically improving the water saving effect of the cooling tower. The utility model is realized by the following technical scheme that the hyperbolic cooling tower water recovery
