[Industrial applications]

 The present invention relates to a filler unit for a white smoke prevention cooling tower, which is intended to prevent the generation of white smoke during operation of the cooling tower in the cold season.

[0002]

[Prior art and its problems]

 Conventionally, when a wet cooling tower is operated, the hot and humid air discharged from the cooling tower is mixed with surrounding air and rapidly cooled, resulting in supersaturated air and fog to form white smoke, which is generated in the cold season. In addition to causing serious damage due to icing on buildings, roads, trees, etc., it may cause misidentification of fires, visibility problems on highways and aircraft control problems.

As a technique for preventing the generation of this white smoke, a dry packing material in which only the upper ends of the packing plates are sealed to form a hollow ventilation path is installed in the packing unit of the cooling tower. There is known a method of filling and preventing generation of white smoke.

However, although the use of the dry filler having only the upper end sealed has a considerable white smoke prevention effect, when a plurality of filler units are stacked and arranged, the dry filler and the wet filler of the lower filler unit are arranged. Since the water bounces from the top of the filling material, the humidity of the air passing through the upper dry filling material rises, and the efficiency of white smoke prevention tends to decrease.

[0005]

[Means for Solving the Problems]

 The present invention is to solve the above-mentioned problems, and its gist is a filler unit having a dry filler and a wet filler, which are stacked and arranged in multiple stages in a cooling tower. The dry-filling material closes the upper ends of the two filling plates, keeps the filling plates at a predetermined interval by a retaining portion protruding in the middle of the filling plates, and keeps the lower end from air This is a filler unit for a white smoke prevention cooling tower, in which water splash prevention portions are formed in substantially parallel from the suction side to the discharge side.

[0006]

[Function of the device]

 Since the present invention is a filler unit in which a dry filler having a water splash prevention plate protruding from the lower end is arranged, if the filler units are arranged in a stack, the lower filler unit can be Prevents water splashes that bounce off the tops of the dry and wet fillers from entering underneath the upper filler unit, preventing the humidity of the air passing through the dry fillers from rising, thus generating white smoke. Has the effect of suppressing

【Example】

 An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the dry filling material used in the present invention, and FIG. 2 is a side view of an example of a filling material unit in which the dry filling material and the wet filling material of FIG. 1 are arranged side by side. FIG. 3 is a schematic view, and FIG. 3 is a front view showing another embodiment of the dry filling material used in the present invention.

As shown in the partially cutaway perspective view of FIG. 1, the dry-filling material used in the present invention has an uneven corrugated pattern 11 formed on the front surface except the upper end, and a large number of retaining portions 3 projecting in the middle portion. In addition, the upper end portion between the filling plates 1 and 1 formed by projecting and forming the water splash prevention portion 4 on the lower end portion is formed with the closing portion 2 by means of fusion or joining by an adhesive. The tip of the retaining member 3 and the water splash prevention unit 4 formed in 1-1 is joined to the adjacent filling plate 1-2 to be integrated, and the water splash prevention unit 4 formed at the lower end is When installed in the cooling tower, they are provided so as to be in a substantially parallel state from the air intake side X direction to the air discharge side Y direction, but preferably, as shown in the side view of FIG. It is projected slightly upward to the right with respect to the suction side X direction.

It is necessary to project the water splash prevention portion 4 on the lower end portion of one filling plate 1-1 of the dry filling material a, and project the water splash prevention portion 4 on the other filling plate 1-2. Instead, the tip of the water splash prevention portion 4 is bonded and fixed to the inner surface of the adjacent filling plate 1-2 to be integrated.

As described above, the dry type filler a having the hollow ventilation path and the wet type filler b are arranged in the order of bbbaba through the retaining section 3 as shown in a schematic side view of FIG. Then, when the filler unit A-1 is configured and the filler unit A-2 is stacked on the filler unit A-1, the dry filler a in the filler unit A-2 is filled. It is preferable that the wet type filler b in the material unit A-1 and the wet type filler b in the filler unit A-2 are arranged directly above the dry type filler a in the filler unit A-1. Good.

Between the filler unit A-1 and the filler unit A-2, as long as the arrangement of the dry filler a and the wet filler b is set as described above, it is arranged between a and a. The value of b may be one to several sheets and may be a repeating sequence or a random sequence.

[0012]

[Effect of the device]

 Since the present invention has the above configuration, it has the following effects. In other words, by forming a water splash prevention part on the dry filling material of the present invention, it is possible to prevent water from splashing back from the lower filling material unit when the filling material unit is stacked in multiple stages. Since the increase in the humidity of the air passing through the material can be suppressed, the effect of preventing the generation of white smoke is great.
