Although the white mist at the air outlet of the cooling tower has no influence on the performance of the cooling tower, the white mist can bring adverse effects on plant operation, working environment, road traffic safety and the like, can also cause equipment corrosion of plant equipment areas, and causes a great amount of loss of circulating water of the cooling tower, so that a mist eliminating device needs to be arranged in the cooling tower.
In the existing cooling tower fog dissipation device, one working mode is to control and adjust the spray liquid, and the generated damp and hot air is reduced by reducing the amount of the spray liquid, so that the white fog is eliminated, but the mode is not suitable for being used in a cooling tower, and the heat exchange efficiency is greatly reduced; the other working mode is that a structure is additionally arranged at the front end of an air outlet of the cooling tower to reduce the temperature and the humidity of the damp and hot air, for example, an induced draft system is additionally arranged, but in the working mode, extra kinetic energy is consumed, energy consumption is more, and the loss of circulating water in the cooling tower is increased, particularly in a closed cooling tower; therefore, how to reduce the energy consumption of the cooling tower in the fog dissipation work on the premise of not adjusting the spray liquid becomes a problem to be solved urgently in the industry.

Example two
As shown in fig. 14, in which the same or corresponding components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, only the points of difference from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that:
in this embodiment, the tower further comprises an upper water baffle 4 and a lower water baffle 5 which are arranged at the connecting gaps between the upper side and the lower side of the adjusting plate 21 and the tower body 1.
Further, the upper water baffle 4 and the lower water baffle 5 are obliquely arranged towards the middle part of the tower body 1.
Specifically, the adjusting plate 21 is movably mounted in the tower body 1, so that a mounting gap exists at the rotating position of the adjusting plate 21, the water baffle plate is arranged outside the mounting gap in a covering mode, spraying liquid is prevented from flowing out through the gap, and the loss of the spraying liquid is reduced.
Working procedure
Step one, when the pipeline is operated, working fluid flows in the coil pipe, the outer wall of the pipeline is wrapped by spraying liquid, heat in the working fluid is transferred to a water film outside the pipeline through the pipe wall, and the water film is continuously evaporated under the action of wind and takes away the heat;
step two, the spray liquid after heat exchange at the coil pipe flows downwards into the filler, and evaporation heat exchange is continuously carried out, so that the temperature of the spray liquid is lower;
in the environment with high external temperature such as summer, the adjusting plate 21 is in a vertical state to prevent the blocking caused by the spraying liquid flowing downwards;
step three, the air in the filler area is changed into saturated damp and hot air after heat exchange, and is discharged out of the tower body 1 by the fan assembly 104 to enter the atmosphere;
step four, in the environment with low external temperature such as winter, white fog is easily generated at the air outlet of the fan assembly 104, at this time, the fastening pieces 2232 are firstly loosened from the operation rod 222, and then the operation rod 222 drives the control plate 221 inside the tower body 1 to transversely move along the negative direction of the X axis;
step five, the control plate 221 after traversing drives all the adjusting plates 21 to synchronously rotate;
step six, the adjusting plates 21 are inclined after rotating, the distance between the adjusting plates 21 is reduced, the direction of the spraying liquid is changed, the speed of the spraying liquid is increased, and the contact area between the spraying liquid and the filler is reduced, so that the amount of damp and hot air generated after heat exchange in a filler area can be reduced, the temperature and the humidity of the generated damp and hot air are reduced, and the white fog phenomenon at the air outlet of the fan assembly 104 is eliminated;
and step seven, the operating rod 222 is fixed again through the fastener 2232, and further the control plate 221 and the adjusting plate 21 are fixed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
