Technical performance of ladle with inclined wave cooling tower

Double oblique wave water filler, with good thermal performance, ventilation resistance is small, good assembly rigidity, carrying capacity characteristics. This kind of packing is widely used in natural ventilation cooling tower and countercurrent large cooling tower. It has the characteristics of large specific surface area and good cooling effect. It is one of the most widely used cooling tower packing in industry.
Thermal performance:
Material: modified PVC, leaching filler height: h = 1.5m, filler for the flame retardant, the oxygen index ≥ 38. The main body of the double oblique wave filler is a sine wave, and the corrugations are arranged in a number of sections. The corrugations are concave and convex, while the sine wave is at an angle of 750 with respect to the horizontal direction. The corrugations and the sine wave are at an angle of 900, The level of 150 angle, which is the main feature of the double ramp, this set to avoid the water flow in the formation of water droplets directly on the flare, leaving the flow gradient gradient extension film to extend the water vapor in the filler section of the heat exchange time , To improve the cooling effect.
As the panel ramp oblique two times staggered, was vertical "W" shape, so that the length of the vertical expansion of the increase, so the expansion of the board area increased, and because of the setting of the retention wave and ramp and the angle of the reasonable design, So that the effective area of ​​water flow film increased. Because the cooling process of the thin film cooling tower is mainly carried out on the surface of the filler film, the cooling efficiency of this process is about 70% of the efficiency of the whole cooling tower. Therefore, the effective area of ​​the film becomes an important index of the heat dissipation effect.
Resistance performance:
For the cooling tower, the packing resistance is another basic performance relative to the thermodynamic performance, often due to the increase in the thermal performance of the filler, the offset decreases the film size and increases the amount of film, but the test results reflect the resistance is too large, and ultimately affect the synthesis Cold effect. Therefore, the rational design of the distance between the packing sheet and the air flow channel is the key technology to solve this contradiction, especially the natural ventilation cooling tower, the pumping force is small, it is formed by the difference between the density of air inside and outside. Double-oblique fillers take this feature into account, increasing the size of the channel, the film from the size of 31 mm, than the current commonly used fillers are large, and in the filler plate type, the lower end of the set of 30 mm long section, so Airflow in the heat exchange process continue to be rectified, reducing its resistance.
Mechanical properties:
The upper and lower channels of the double oblique wave filler are assembled into honeycomb, and the rigidity is good. The bonding method is arranged on the 1000 × 500 (mm) plate surface to improve the overall strength.
