Principle and Construction of Circular Counterflow Fiberglas

The circular counter-flow FRP cooling tower is to reduce the water temperature by using the automatic rotating water distribution mode, the heat conduction of dry air and the evaporation of circulating cooling water to take away the latent heat of gasification. Circulating cooling water with a certain pressure enters the cooling tower through the water inlet pipe, and is atomized into mist steam with a diameter of 0.11mm under the action of swirl injection of the atomizer, and the reverse thrust generated by the injection drives the automatic rotating device to rotate, so that the atomized water fills the whole tower. The axial fan installed at the top of the tower rotates, which forcibly sucks the cold and dry air from the surrounding environment into the cooling tower through the air inlet window for mass transfer and heat transfer with circulating cooling water. The atomized water jet from the atomizer has a fast flow speed, and has the functions of entrainment and entrainment, so that a certain negative pressure is generated around the atomizer, which increases the exhaust volume and intake air speed of the cooling tower from the surrounding environment, and at the same time drives the bottom air to flow upwards, so that the cold and dry air can be mixed and contacted with the water mist more fully (the gas-water ratio can reach about 1.3), and the particles of the atomized water stream are further refined, and the diameter can be reduced to 0.012mm, so that the mist flows after the gas and water are fully mixed.

 

Circulating cooling water has three processes: rising, suspending and falling in the cooling tower. At the same time, there are two processes of downstream cooling and countercurrent cooling, so the contact time with cold and dry air is longer and more sufficient, and more heat is taken away. At the same time, due to the cancellation of packing, the phenomenon of air resistance does not exist, which reduces the power of the motor driving the fan to rotate, and achieves the effects of reducing operating costs and improving the temperature difference between inlet and outlet water. In addition, the contact area of atomized water and air far exceeds that of packed cooling tower. Based on these points, the atomization cooling tower has higher heat exchange efficiency, smaller motor power fan model and more obvious energy saving effect.

 

1. FRP chassis and shell

 

Brand-new glass fiber reinforced resin (FRP) is made of high-quality glue, which is more corrosion-resistant, weather-resistant, heavy-pressure-resistant, and better in sealing than ordinary glue, and the tower body is thicker than ordinary glue. At present, most of the domestic glue is used in the market, and recycled glass fiber is used, which is not strong in hardness and even worse in resistance.

 

2. Motor

 

The motor is an energy-saving motor, and its speed is slow, but its efficiency is the same as that of a fast motor, because our motor has high pole pairs and many windings, so as to achieve the effect of energy saving and good insulation and sealing;

 

3. Wind blades

 

Made of sand aluminum alloy, it is corrosion-resistant and weather-resistant, and it does not rust, and its service life is greatly increased;

 

The main thing is that our blades are very quiet.

 

4, cooling film

 

The brand-new PVC is modified with flame retardant, which has good heat dissipation, weather resistance and corrosion resistance. Most films on the market are produced with recycled materials, which not only has poor heat dissipation effect, but also is not durable. Liangyi uses matt films made of brand-new PVC plastics.

 

The circular countercurrent tower of our company is smooth, beautiful in tower design, lightweight, energy-saving in structure and convenient to maintain;
