AI Technical Summary

Problems solved by technology

[0004] Natural ventilation cooling towers are tall (ranging from tens of meters to hundreds of meters), engineering difficulty and investment are large, and the cooling temperature difference is small; mechanical ventilation cooling towers use electric fans to force the air, and use various types of corrugated packing as liquid distribution and mass transfer components , the technology is mature, but the power consumption of the electric fan is high, the maintenance cost is high, the packing is easy to block, and the cooling performance decays quickly

[0005] There are two types of traditional spray cooling towers. One structure is forced draft by an electric fan, spraying mass transfer with a fixed nozzle group. The electric fan has high energy consumption and high maintenance costs, and the spray water mist concentrates the ventilation resistance, and the cooling performance is poor.

Another type of structure is a spray cooling tower that adopts a swirl atomization propulsion device for mass transfer and liquid distribution, which realizes no filler and no electric fan, which solves the shortcomings of easy blockage of mechanical ventilation cooling tower filler and high power consumption of electric fans to a certain extent. However, during the use of the existing spray cooling towers that use swirl atomization propulsion devices for mass transfer and liquid distribution, they are driven by hydraulic power, and the low-pressure water flows through the swirl atomization nozzles to generate atomization, increasing the surface area of ​​the water, and atomizing The droplets and the air entering the tower exchange heat under foggy conditions to achieve the cooling effect, which changes the traditional structure of the mechanical ventilation cooling tower and does not require water spray fillers. Since there is no water spray filler in the spray hollow cooling tower, only the nozzle will The water is atomized to cool down, so the ventilation resistance of the cooling tower is small, and the air will take away the tiny water droplets, which is very easy to cause the loss of floating water in the cooling tower. However, at present, only the water collector is used for cooling, and most of the small water droplets still cannot After being collected, it is taken out of the tower with the heat, causing floating water, and the water collection effect is not ideal. At the same time, this part of the floating water cannot be used rationally, wasting resources, and is not environmentally friendly.
