1. After the FRP cooling tower is installed, the debris and dirt on the pipeline, water collector, filler surface and water collecting tank should be carefully removed to avoid blockage.
2. Before use, test run should be carried out first to check whether the fan and glass fiber reinforced plastic cooling tower are installed smoothly, whether the water distributor is running normally, whether the water distribution nozzle is evenly discharged, and whether the motor moisture-proof measures are tight.
3, glass steel cooling tower use, should always observe, check the fan operation, including current, voltage, fan vibration, noise, gear oil level, whether there is oil leakage or belt drive is loose, whether there is slippage, water distribution is normal.
4. The turbidity of the influent of the FRP cooling tower is not more than 10 mg/L. During operation, regular sewage discharge or increased water quality stabilization treatment should be considered according to the water quality.
FRP cooling tower is prone to internal corrosion, which is not easy to find and has strong destructive power. The newly replaced packing in an acid station workshop of a company is prone to scaling and deformation. The structure of FRP cooling tower is schematic. The beams, columns, diagonal braces, etc. of FRP cooling tower are scattered on all frames filled with FRP extruded profiles through small holes in the water distribution pipes in the tower. Truss type connecting materials are adopted. When hot water flows through the surface, water, a water film is formed and air connection, the connection between all other components is also used to prevent heat exchange. The filler prolongs the residence time of cooling water in the cooling tower. The tower body not only has a good retention time and increases the heat exchange area, thus increasing the heat exchange amount and achieving the overall rigidity, but also can be subjected to multiple forces to make the tower body strong to the cooling effect.
However, the long-term use of the filler will cause bending deformation close to the strength of the steel-structured FRP cooling tower, resulting in its performance degradation. In addition, the FRP cooling tower does not use filler in acid and sulfur, but in the cooling water of the tower internals, the filler is seriously fouled, and even the upper swirl nozzle is used on the Jieban cloth water pipe, resulting in fracture and collapse of the nozzle after spraying, resulting in cooling efficiency decline, the water is sprayed on and then falls down, and the water is distributed in the space of the high maintenance tower in the form of tiny droplets, prolonging the residence time of the droplets in the air.
1, glass fiber reinforced plastic cooling tower dripping noise reduction pad: for low noise and ultra low noise cooling tower, specially designed good water permeability muffler pad, which is equipped with a layer of oblique wave plate, greatly reducing the dripping noise.
2. Sound absorption facilities of glass fiber reinforced plastic cooling tower: shielding and sound absorption grating with sound absorption materials are installed on the air outlet of the upper tower body for ultra-low noise cooling tower, which reduces the noise of fans and motors. Mushroom-type sound absorption grating is installed for small towers.
3. Lower tray of glass fiber reinforced plastic cooling tower: the cooling towers of shallow water tray and deep and deep water tray are equipped with lower water tray for water storage. According to the ordering requirements, they can be equipped with overflow water, sewage, automatic and manual water supply pipes, which can directly absorb water from the lower tray.
In the use of the cooling tower is to achieve a certain cooling effect, the cooling effect depends on the cooling fin, fan air volume, cooling tower water, ventilation conditions, installation of the cooling tower location will also have a certain impact on its effect, let's take a look at the cooling tower cooling fin and fan air volume on the cooling system:
① Heat sink: it is the key component of cooling tower. PVC sheet hot pressing or heat suction type is generally used for small towers, and wood is used for large towers. The main purpose is to make the contact surface between air and water the bigger the better without affecting wind resistance, and the heat exchange rate is also the maximum. The two parameters that affect the heat transfer effect of heat sink are mainly the shape and height of heat sink. During the installation of water tower, try not to damage the heat sink, in order to avoid the heat sink water flow is not smooth.
② Fan air volume: It mainly accelerates the air flow in the tower, accelerates the heat exchange between air and water, and takes away heat. The air volume of the fan is mainly affected by the shape of the fan blade, that is, the width and length of the fan blade and its deflection angle, the fan blade speed, the installation angle, the speed, the motor and the transmission ratio, etc. In addition, under the condition of a certain air volume, the cooling effect of the same type tower with a small cooling water volume is better than a large cooling volume.
