Characteristics Of Closed Cooling Tower
Structural performance and characteristics of closed cooling tower
- Efficient heat exchange coil:
Oval aluminum alloy tubes are used, and all the tubes are welded into coils after passing the inspection. In order to ensure no leakage, each set of coils is subjected to an air pressure test of 1.6MPa in water. The use of elliptical tubes can increase the surface area and water receiving area of the heat exchange tubes. The tubes are arranged crosswise, and the reasonable tube spacing design and the spray water form a uniform water film on each tube wall, which greatly enhances the effect of evaporative cooling. . The air and cooling water outside the coil of the closed cooling tower flow in reverse, and the elliptical tube shape and cross-arranged pipeline arrangement make the coil have excellent heat exchange effect and low air resistance.
- Efficient spray water circulation system:
The newly developed ABS special spray nozzle has the advantages of large spray water volume, uniform spray water distribution, and no clogging. The reasonable spray height of the water distribution pipeline and the arrangement of the nozzles can form a uniform water film on the outer wall of the coil. Avoid wall flow.
The spray water circulation system is specially equipped with an anti-scaling device to slow down corrosion and increase heat exchange effect.
The outdoor circulating water pump is adopted to reduce energy consumption and maintenance.
- Reasonable water-air ratio:
According to the scientific research results of cooling tower experts from Shanghai Jiaotong University for many years, the spraying circulating water volume and cooling air volume of the tower are the best choices.
- Efficient water collector, good water saving effect:
The three-dimensional water collector made of the latest FRP material has small air resistance and high water collection efficiency, which accounts for more than 99.99% of the circulating water. In order to facilitate the internal maintenance of the cooling tower, the water eliminator is designed to be detachable. The overall water consumption of the closed cooling tower can be controlled between 0.5-1%, which is one-fifth of the water consumption of the closed cooling tower.
- High-efficiency and low-noise fan:
The wide-leaf, large chord length, and space-distorted aluminum alloy cooling tower special fan that has won the National Invention Award has high efficiency, small vibration, low noise, and low energy consumption. The fan and the motor adopt a direct connection type, without deceleration, and are easy to maintain. The motor adopts an outdoor high-temperature-resistant closed motor.
- Solid anti-corrosion tower body:
In order to maintain the normal operation of the closed cooling tower in the harshest environment, the structural parts of the tower body and the water collection chassis are all made of stainless steel plate folding, and the tower body panels and fan ducts are made of corroded glass fiber reinforced plastic components. All connections in the closed cooling tower are made of stainless steel. This closed cooling tower series adopts modular design, which is conducive to layout.www.gwbrefrigeration.com
