Under the water-saving working condition, the water-saving modules 15 are distributed in an inverted splayed shape, the upper ends of the water-saving modules 15 are carried on the baffle plates 14 and form a sealing surface together with the baffle plates 14, and wind power coming from the outside is prevented from penetrating through the sealing surface.
The specific working principle of the invention is as follows:
the water distribution basin 10 sprays the water onto the tubular heat exchanger 8 through the spraying system 9 and then flows into the water collection basin 1, and the water in the water collection basin 1 is pumped back into the water distribution basin 10 through the water pump 27; under the action of the fan 13, outside air enters from the tubular heat exchanger 8 through the air inlet grille 25, enters the tower through the water collector 26, and performs heat and moisture exchange in the process of passing through the tubular heat exchanger, and the air entering the tower reaches or is close to a saturated state and has a high temperature, which is called as damp and hot air for convenience of presentation.
As shown in fig. 1 and 3, under the water-saving working condition, the water-saving module 15 is close to the corresponding baffle 14; a side air inlet cavity is formed between the outer side of the water-saving module 15 and the tubular heat exchanger 8; the air inlet of the side air inlet cavity is only provided with the tubular heat exchanger 8, and the air outlet is only provided with a transverse channel of the water-saving module 15; one side of the lower end of the water-saving module 15 without the hinge is contacted with one side of the air inlet shutter 6 to form a sealing structure, so that air blown in from the lower end of the air inlet shutter 6 is prevented from flowing into a side air inlet cavity; the only path for the air after passing through the tubular heat exchanger 8 is through the water conservation module 15, the water conservation module 15 being formed by overlapping longitudinal path members 18 and transverse path members 19 shown in fig. 6-10, respectively. Under the action of the water-saving module frame 23, the transverse channel and the longitudinal channel of the water-saving module 15 are more reliably separated.
Meanwhile, the bottom end of the water-saving module 15, the mounting frame 4 and the air inlet shutter 6 form a bottom air inlet cavity; the air inlet of the bottom air inlet cavity is an air inlet shutter 6, and the air outlet is only a longitudinal channel at the bottom of the water saving module 15.
At this time, the air inlet shutter 6 below the water saving module 15 is opened, and external air enters under the action of the fan 13, which is called dry and cold air for convenience of presentation.
The only path for this portion of dry and cool air is the longitudinal path through the water conservation module 15. Inside the water saving module 15, two air streams are heat exchanged. The wet hot air is cooled and condensed, the absolute humidity of the air is reduced, and the dry cold air is heated and the absolute humidity is unchanged. The condensed water drips from the transverse channel of the water-saving module 15 and flows into the water-collecting basin 1, so as to achieve the purpose of saving water. The two air flows passing through the longitudinal channel and the transverse channel of the water-saving module 15 are mixed in the area at the lower part of the air duct 12, and the absolute humidity of the mixed air flow is far lower than that of the wet hot air before entering the water-saving module 15. The air discharged through the air duct 12 is not saturated and can play a role in eliminating the plume.
As shown in fig. 11, in the non-water-saving condition, when the ambient temperature rises and the outside air temperature is higher than the dew point temperature of the hot and humid air in the cooling tower, the water-saving module 15 is not functional, and the resistance of the hot and humid air flow can be reduced by adjusting the position of the water-saving module 15. The water-saving module frame 23 is provided with a pull ring 22, the other end is provided with a hinge 21, and the water-saving module frame is fixed on the cooling tower channel 4. And is connected to a rope 22. the rope 22 is passed around the support beam 7 in the middle of the cooling tower. Standing on the cooling tower channel 4, the position of the water-saving module 15 can be adjusted by manually pulling the rope 22, and the water-saving module can rotate along the hinge 21 until the water-saving module abuts against the support beam 7 in the middle of the cooling tower. The air inlet shutter 6 below the water saving module 15 is closed at this time. The damp and hot air passing through the tubular heat exchanger is directly discharged through the air duct 12, and a small part of damp and hot air passes through the water-saving module 15 longitudinally and then is discharged through the air duct 12.
