How to Improve the Energy Saving and Reducing Efficiency of Cooling Tower Fan
Date：2019/11/19 Views：3774 【BACK】
Cooling tower fan is the core equipment of the circulating water system, the circulating water equipment management situation, whether it is from the number of equipment, maintenance workload, power consumption and other aspects of terms, the cooling tower fans are occupying a large proportion. The number of fans accounted for 57% of the total plant equipment, maintenance work accounted for 60% of the total, electricity consumption accounted for 22% of the total. How to reduce energy consumption, reduce the labor force to ensure the long-term operation of the equipment, the following simply talk about the measures:
1, cross-flow cooling tower should control the top of the filler to the lower edge of the fan suction height is equal to or greater than the fan diameter of 0.2 times.
2, the countercurrent cooling tower packing top to the inlet between the air duct shrinkage of the height should meet the following requirements:
1) When the top cover of the tower is flat, the angle of the air flow from the top of the packing should be less than 90 °. When the guide ring (umbrella) is provided under the flat roof cover, The surface of the air flow contraction section angle can be used 90 ° ~ 110 °.
2) When the top of the tower from the collector above the shrinkage type, the contraction of the cover of the top angle should be used 90 ° ~ 110 °.
3, cross-flow cooling tower of the water filler from the top to the bottom of the tower should have a vertical axis of the contraction angle. The dripping angle of the drip-type leaching filler is preferably 9 ° to 11 °; the shrinkage angle of the film-type leaching filler is preferably 5 ° to 6 °.
4, the two sides into the wind countercurrent cooling tower should be set in the middle of the wind partition, the upper edge of the partition from the support beam beam 200 ~ 300MM, the lower edge of the tower into the pool below the water.
5, cross-flow cooling tower should be set to prevent air from the bottom of the filler to the surface of the short-circuit flow between the measures.
