Description
Technical Field
The invention relates to the field of industrial and civil cooling equipment, in particular to a bionic water condensation device for a cooling tower.
Background
Cooling towers are important devices in circulating water cooling systems, and are generally divided into open cooling towers and closed cooling towers; compared with an open cooling tower, the high-temperature working medium of the closed cooling tower flows in the coil pipe to prevent the working medium from being polluted by spray cooling water and air, so that the cleaning of the working medium can be ensured, and in addition, the cooling capacity can be smaller than that of the open cooling tower due to the dividing wall type heat exchange of the closed cooling tower, and the evaporation loss of the working medium can be smaller than that of the open cooling tower, so that the water recovery potential of the open cooling tower is greater than that of the closed cooling tower.
The cooling water quantity loss in the circulating water cooling system mainly comes from the cooling tower, and mainly comprises evaporation loss, wind blowing loss and pollution discharge loss; the evaporation loss is the amount of water which is evaporated into the air when the circulating cooling water is in direct contact with the air for heat exchange, and the water loss of the part is about 1.2% -1.6% of the total amount of the circulating water; the wind loss is caused by the pumping force of the wind barrel, and small water drops outside the air blowing tower are blown out, and the water quantity of the drifted water drops accounts for 0.2% -0.5% of the circulating water quantity; for a thermal power plant, the evaporation loss and the wind loss account for 35% -70% of the total water consumption of the thermal power plant, and the water loss is serious; in addition, as the evaporated moisture enters the air, the temperature and the humidity of the air are increased, and in winter, the hot and humid air is discharged out of the tower and mixed with the external cold air, so that foggy containing a plurality of tiny liquid drop groups can be formed, the road is frozen, the air visibility is reduced, and the environmental and safety problems are brought, therefore, the water can be saved by recycling the evaporation and the wind blowing water quantity of the cooling tower, and the environmental and safety hidden dangers can be eliminated.
For example, the prior patent document CN107449315A discloses a hyperbolic cooling tower water collector, which comprises a plurality of water collecting module groups, each water collecting module group comprises a plurality of water collecting blades horizontally arranged at intervals, the water collecting blades are continuous multi-waveform sheet bodies formed by one-time compression molding of aluminum alloy materials, and voltage is applied to steel wire ropes of adjacent water collecting module groups, so that static electricity is generated between the water collecting blades, and an electrostatic magnetic field is formed to achieve the effect of rapid condensation of water vapor; however, the water collector needs to be added with an additional power supply, and the safety of the wet air is difficult to ensure because the humidity and the temperature of the outlet of the wet air after passing through the cooling tower are high.
For another example, the prior patent document CN103743289a discloses a cooling tower defogging and water receiving device, which consists of a cold air supply system, a condensation system, a mixed bellows and an air intake adjusting device, wherein the cold air supply system consists of a refrigerator, a refrigeration exchanger, an axial flow fan, a reducing air cylinder and an air collecting bellows, and the air flow which is heated and humidified after heat exchange of the cooling tower is cooled and dehumidified in the condensation system, so that the purpose of defogging and water receiving is achieved; however, the device has large investment and high energy consumption, and a plurality of systems are required to coordinate to work, and a certain distance is still kept from the energy-saving and environment-friendly targets.
For another example, the prior patent document CN204987933U discloses a deep condensate recovery demisting device in a cooling tower, comprising a condensation module, a shutter and a wind barrier; the hot and humid air in the tower and the cold and dry air outside the tower pass through the condensing module to perform heat exchange at the same time, the water vapor is condensed into water drops to be recycled, and the hot and humid air in the tower and the cold and dry air outside the tower are mixed at the upper part of the condensation to reduce the moisture content, so that the effects of saving water and removing fog are achieved; however, because the fan needs to be additionally arranged, and the wind resistance of the condensing module is large, the air inlet quantity is very easy to be insufficient when the pressure head is not high, and the cooling efficiency of the cooling tower is influenced under the condition that the design margin of the cooling tower is not large.
Accordingly, there is a need for improvement and development in the art.
