How much do we know about cooling tower packing? The method of removing scales was introduced earlier. Today we will continue to talk about the advantages of cooling tower packing and how to replace it. I believe that after reading these, readers will have a preliminary understanding of cooling tower packing. The specific contents are as follows.
1. Advantages of cooling tower packing
The advantages of cooling tower packing are:
(1) Good performance, high cooling efficiency The filler is a film type, and the protruding fine waves make the water contact surface larger. The filler is placed in 3-4 layers, and there is a redistribution process of hot water between the layers.
(2) Good hydrophilicity, small ventilation resistance, the surface is rough, smooth surface filler is good hydrophilicity, the water absorption rate is less than 0.015%, so that more water flows into a film without splashing, so that water and air are more fully At the same time, the surface disturbance of water and air is great when flowing. After the filler is assembled, the air inlet surface is a honeycomb-shaped deflector, which has a good air distribution effect, which improves and stabilizes the heat exchange strength of the water vapor. The air inlet end is inclined at an angle of 30 °, which effectively reduces the water loss. A water collector designed according to the impact separation method is provided at the end of the packing, so that the loss of drift water can be effectively controlled within 1 / 100,000.
(3) The core material of the cooling tower is made of high-quality PVC polyethylene sheet. Due to the use of trapezoidal wave packing, the heat radiation area has a large growth factor, the water flow has good distribution performance on the board surface, and the water and air flow are disturbed when passing through the board surface Great advantages. The filler is not easy to deform, high temperature resistant, anti-aging, and has good flame retardant performance and small wind resistance coefficient. Easy to install, easy to clean, and easy to transport.
(4) The heat dissipation of the packing accounts for more than 85% of the entire temperature drop in the cross flow tower. The heat dissipation process of the cooling tower is mainly carried out on the surface of the heat dissipation filler plate. The water film on the filler surface flows down slowly. The innermost water film is high-enthalpy humidity air with 100% humidity. The value of fresh air entering the tower increases the air enthalpy of the tower. As the concentration of water molecules decreases, the water molecules in the circulating hot water continuously evaporate from the liquid state to the gas state, thereby taking away the latent heat of steam.
