FRP cooling tower and FRP cooling tower both sound like the same effect, but since the two things are naturally different in use, let's take a look at the differences between the two devices:
1. FRP cooling tower is a structure used for cooling water in power plants. Its height is generally determined according to the size of the power plant's units. It is a structure used by power plants to save water and circulate water. The working principle of the cooling tower is to use the blown-in wind and the water sprinkled from the top to form convection to discharge the heat source, and part of the water evaporates in the convection to take away the corresponding latent heat of evaporation, thus reducing the water temperature.
2. FRP cooling towers are mainly used in power plants and large production plants. Its main function is to cool circulating water. Generally, the water with reuse value after preliminary treatment is passed into the cooling tower to cool the water and then reused to save water. Generally, the water treated by the cooling tower is used to cool other articles in other processes. Therefore, the water temperature is very high, so the cooling tower needs to be used for cooling and reuse. The cooling tower structure: the water to be cooled is sprayed downward at the top of the water tower through pipes. In addition, the wall of the water tower is equipped with a blower to blow air in, while the top is equipped with a large suction fan to draw air out of the top of the tower, thus facilitating the flow of air and accelerating the cooling of water. Heat dissipation plates made of tortuous PVC glue are separated above and below the spraying pipes to increase the heat dissipation time of water droplets.
Gradually entering the status of glass fiber reinforced plastic cooling tower in summer, the cooling tower is prone to some problems in use, among which air leakage has the greatest impact on the cooling tower, which will affect the cooling effect and the safety of the cooling tower operation. The air leakage of the cooling tower mainly includes the air leakage of the tower body, the air leakage of the platform and the air leakage of the packing damage. Let's talk about the impact of the air leakage of the cooling tower specifically:.
1. Air leakage from the tower body of the cooling tower reduces the exhaust air volume in the tower. According to the increase of air leakage from the tower body of the cooling tower, the heat exchange between cold air and circulating water in the tower is relatively small, the heat discharged will naturally decrease, and the cooling effect of the cooling tower will decrease. Therefore, the heat loss in the cooling tower increases, the thermal efficiency of the cooling tower decreases, and the air volume of the cooling tower fan increases, resulting in the motor current increases, thus increasing.
2. Air leakage from the cooling tower platform will directly cause cold air to enter the tower directly from the air leakage point of the platform, greatly increasing the output of the cooling tower motor and fan, forcing the cooling tower to reduce load operation. When the air leakage from the cooling tower maintenance platform is serious, it will directly cause no gravity at the air inlet of the cooling tower. Cold air will directly enter the cooling tower from the maintenance platform, and then be removed from the tower by the cooling tower fan. Since cold air does not pass through the cooling tower packing, there, there, there, cooling tower cooling effect is directly affected.
3. Damage and air leakage of cooling tower packing will lead to dense local water distribution in the tower, and the cold air and circulating water will not achieve sufficient heat exchange, which will not only affect the cooling effect of FRP cooling tower, but also gradually increase the cooling tower at the packing damage over time as the water pressure and air volume at the filling leakage increase, while the low load operation of cooling tower may cause the service life of motors and fans.
For users who use cooling towers, it is very important to understand the matters needing attention in the purchase of products. Next, let's explain it for you.
1. In principle, the selection and configuration of the cooling tower corresponds to the host and the cooling pump one by one, or one host can correspond to multiple cooling towers and be controlled by linkage with each other.
2, should be based on the local water quantity, water quality, water temperature and outdoor calculation of wet bulb temperature and other meteorological natural conditions, with reference to the manufacturer's selection diagram and unit cooling water parameter requirements and technical and economic factors, determine the type of cooling equipment and the size of the cooling water volume.
3. The supplementary water quantity of the cooling tower circulating water supply cooling water system includes evaporation loss, floating water loss, sewage loss and discharge water loss. The cooling tower with low energy consumption and less floating water quantity should be selected. The supplementary water quantity of air-conditioning cooling water should be controlled at 1.2~1.5 of the total circulating water quantity of the system. When the water quality is good, the small value should be taken and when the water quality is poor, the large value should be taken.
