At present in the industrial, civil, air conditioning and other industries circulating cooling water system, the widely used filler cooling tower is the use of film or drip theory, the need to cool the circulating cooling water evenly distributed to the filler, through the formation of water film or water droplets And then increase the water and cold, dry air mass transfer, heat transfer area. The cooling tower of the packing tower is equipped with a rotating mechanism such as a motor and a reducer to drive the fan to rotate, and the cold and dry air in the surrounding environment is sucked into the tower. The heat of the circulating cooling water is brought into by the heat conduction and the cooling of the cooling water To the air, to achieve the purpose of reducing water temperature. This cooling tower, water and air contact area is small, the filler on the air resistance, water film, the formation of water seal within the filler, air circulation area is reduced, only to increase the fan motor power to overcome this drawback, energy consumption relatively bigger. After a period of time, the filler is blocked, the film forming effect of the water is affected, the air flow is worse, the overall cooling effect of the tower will be greatly reduced, so this tower failure rate is high, the maintenance amount is large and the maintenance cost is high. After the packing is blocked, the weight of the tower is increased, causing the cooling tower to be crushed and shorten the service life. In addition, the traditional filler-type cooling tower on the water quality requirements, water turbidity of 100 mg / l can not work, cooling effect is greatly reduced. While the atomized cooling tower in the water turbidity of 200 mg / l, still work properly. For those with high turbidity of circulating water, absorb water, etc., atomized cooling tower is more applicable. Long-term use, the filler layer to produce a large number of bacteria, algae, bacteria harmful to humans, algae blocking filler, the state has the law, fill the cooling tower to regular sterilization algae. The atomized cooling tower does not have this requirement.
   Automatic spin-type cooling tower to break the traditional filler-type cooling tower film theory, the use of the current international most advanced atomization theory, the use of automatic rotation atomization device instead of the traditional filler and water distribution device, the cooling circulating water dispersed into Diameter of 0.01mm water mist, mass transfer, heat transfer area is greater than the filler cooling tower, the entire cooling tower is basically turned into an empty tower, a significant reduction in the tower system resistance and thus improve the air volume, (atomized water mist in the tower The inside of the jet, by the weight of the fall, to achieve with the cold, dry air downstream, countercurrent two heat exchange, conduction, improve the hot water in the tower of residence time, hot water and axial fan suction cold Surface and gas to water than the full, long heat transfer, exchange, so the treatment of water, the cooling water temperature drop large, low energy consumption, low operating costs. It has been proved that the same flow and temperature drop of hot water, atomized cooling tower than the traditional filler cooling tower, energy consumption reduced by 30%, covers an area of 20%, 50% reduction in maintenance, life extension of three times the above.
   Automatic rotary atomization cooling tower compared with the traditional filler-type cooling tower also has the following unparalleled advantages:
   1, due to no filler, the tower is basically in a hollow state, the fan resistance is small, low noise.
   2, the company's patented technology to produce high-efficiency water collector, effectively reducing the water, water-saving effect is obvious.
   3, the tower with streamlined design, fan and hairdryer with a small gap, resulting in large air volume, wind speed, cooling effect is good.
   4, automatic rotating atomizer using polymer wear-resistant materials, corrosion-resistant, long service life.
   5, the use of modular design, easy to transport, installation, commissioning.
   6, no clogging, no maintenance, stable and reliable operation. Completely eliminate the packing tower due to the circulating water in the impurities blocked packing and packing aging, deformation, brittle crack, cloth nozzle clogging and flushing, packing debris plug the pipe,
   Pumps and heat exchangers and a series of characteristics of the tower and process equipment performance. Completely eliminate the frequent cleaning, replacement of filler and cloth nozzle trouble.

   working principle

  Equipment: Automatic rotating atomization cooling tower by the inlet pipe, automatic rotating atomizer, shell, water collector, fan, motor, into the wind, water tray (water tank), outlet pipes, stents, escalators Generally by the use of manufacturers with their own) and other components (see structure diagram).
    Note: The above is for the structure of the single tower that, for different processing capacity, can be composed of twin towers, multi-tower structure.

    Working principle: automatic rotating atomization cooling tower is through the circulating cooling water and cold, dry air heat conduction and circulating cooling water evaporation gasification latent heat to achieve the purpose of reducing water temperature. The circulating cooling water with a certain pressure enters the cooling tower through the water inlet pipe, and is atomized into the nozzle with the diameter of 0.1mm to the tower top direction under the action of the swirling jet of the atomizer. The anti-thrust force generated by the spraying is driven by the automatic rotating device Rotate, causing the atomized water to fill the entire tower. Installed in the top of the axial flow fan rotation, the surrounding environment of the cold, dry air through the inlet window forced into the cooling tower and circulating cooling water for mass transfer, heat transfer. The atomization water sprayed by the atomizer is very fast and has entrainment and entrainment to produce a certain negative pressure around the atomizer, which increases the ventilation volume and the inlet air flow rate of the cooling tower from the surrounding environment while driving the bottom The air flow up, resulting in cold, dry air mixed with water mist, contact more fully (gas ratio of up to 1.2 or so), atomized water particles have been further refined, the diameter can be reduced to 0.01mm, gas, water mixed The fog flow is sprayed up to the water collector installed on the top of the tower. The water is trapped and returned to the cooling tower in a water curtain. The heat in the air and water is discharged from the tower through the water collector.
   From the above process can be seen, the circulating cooling water in the cooling tower has increased, suspended, down three processes. At the same time cooling also has the downstream cooling and countercurrent cooling of the two processes, so with cold, dry air contact time longer, more fully, take away more calories. At the same time, due to the elimination of filler, air resistance phenomenon does not exist, reducing the fan to drive the power of the motor rotation, to reduce the operating costs and improve the temperature difference between access to the effect. In addition, after the atomization of water and air contact area far more than the filler-type cooling tower water and air contact area. Based on these points, atomization cooling tower heat exchange efficiency is higher, the motor power fan model selection is smaller, energy saving effect is more obvious.
