Abstract

(57) [Summary] [Object] To provide a filler for a cooling tower in which a dry air passage for preventing white smoke generation in a cross flow type cooling tower is arranged at a required position of a wet air passage. [Composition] A filling material in which a dry air passage is arranged at a required position of a wet air passage of a cross flow type cooling tower, and the filling material is substantially horizontal between an intermediate position in the height direction and an upper position of the two filling plate materials. A filler for a white smoke prevention cooling tower, which is formed by forming a cut portion in a direction, and inserting a cap plate into the cut portion to form a dry air passage. [Effect] In the filling material of the present invention, a notch is formed at a position where a cap plate can be easily covered, a cap plate is attached here to form a dry air duct, and the cap plate is removed to switch to a moisture duct. It is possible to prevent white smoke by adjusting the attachment and detachment according to the season.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler for a white smoke prevention cooling tower, and in particular, a dry air passage for preventing white smoke generation in a cross flow type cooling tower is provided at a required position of a wet air passage. The present invention relates to a cooling tower filler.

2. Description of the Related Art Conventionally, a dry air duct is provided for every one or several stacked type packing plate materials to be loaded in a cross flow type cooling tower, and the outside air introduced into the dry air duct is a wet air duct. It is known to prevent the generation of white smoke by lowering the relative humidity by sensible heat transfer with and mixing this dry air with saturated air that has undergone heat exchange in the wet air duct and discharging it outside the tower. .

However, since a sprinkler and a dispersion plate are arranged at the upper end of the packing material loaded in the cross flow type cooling tower, a cap plate can be easily opened and closed to cover the dry flow path. It is difficult to form the sealant and to have a reliable sealing property, and when the fillers are stacked in multiple stages, it is difficult to form the dry air passage in the lower stage.

DISCLOSURE OF THE INVENTION The present invention is to solve the above problems, and the gist thereof is a packing material in which a dry air passage is arranged at a required position of a wet air passage of a cross flow type cooling tower. A cut portion is formed in a substantially horizontal direction between the middle position and the upper position of the two filling plate materials in the height direction, and a cap plate is inserted into the cut portion to form a dry air passage. It is a filler for a white smoke prevention cooling tower.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. 1 shows the invention in a partially omitted perspective view, FIG. 2 shows a side view of a packing material provided with a dry air passage, and FIG. 3 shows a state in which the invention is incorporated in a cooling tower. Shown in the figure.

The present invention is a packing material in which a dry air passage is arranged at a required position of a wet air passage of a cross flow type cooling tower, and is a perspective view in FIG. 1 and a side view in FIGS. As shown, the cut portion 12 is formed in a substantially horizontal direction between the middle position and the upper position of the two filling plate members 11 in the height direction.
Filling material 1 formed by inserting a cap plate 2 into the dry air passage a
Is.

Filling plate material 11 constituting the filling material 1 of the present invention
Is provided with the corrugated portion 13 on the entire surface, and the adjacent filling plate material 1
Spacers 14 are provided on both front and back surfaces in order to hold the first and the first members 11 at a predetermined interval.
If these are arranged side by side as they are, a wet air passage b is formed. On the other hand, the dry air passage a provided in the filler 1 of the present invention is
It is formed by forming a notch 12 in a substantially horizontal direction between an intermediate position in the height direction and an upper position of the two filling plate members 11 and inserting the cap plate 2 into the notch 12. Therefore, the formation portion of the cut portion 12 for inserting the cap plate 2 is formed only at the intermediate position in the height direction of the filling plate material 11, only at the upper position, or at both the intermediate position and the upper position, as required. You may also, the depth of cut is also free,
Further, in the parallel installation direction, the dry air passages a may be installed alternately with the wet air passages b or may be installed at a ratio of one to several wet air passages b. The number of dry air passages a, the depth of cut and the arrangement ratio may be determined according to the situation of white smoke from A.

Further, as shown in FIG. 3, the dry air passage a disposed in the filling material 1 of the present invention is introduced from the sprinkler tank 3 onto the cap plate 2 by the introduced air X by the rotation of the fan 4 of the cooling tower A. In order to prevent so-called carry-over, in which the sprayed water that has flowed down to the fan plate 2 is unevenly flowed along the cap plate 2, it is preferable that the sprayed water is formed to rise in the central direction of the cooling tower A with a slight gradient θ.

According to the present invention, a required number of cap plates 2 are inserted into the notches 12 of the filler 1 and formed by the cap plates 2 in the season when white smoke is likely to be generated, such as the winter season and the rainy season. The air passing through the dry air passage a exchanges heat with the air flowing on the outer wall surface side of the dry air passage a to become low-humidity air, and the low-humidity air becomes supersaturated air passing through the wet air passage b. When mixed and discharged by the fan 4, the discharged air does not generate white smoke even when cooled by the outside air.

[0010]

Since the present invention has the above-mentioned structure, it has the following effects. That is, in the filling material of the present invention, a notch is formed at a position where the cap plate is easily covered, a cap plate is attached here to form a dry air duct, and the cap plate is removed to switch to the moisture duct. As a result, white smoke can be prevented by adjusting the attachment / detachment according to the season, and by forming a slight inclination gradient in the dry air passage, it is possible to take measures against a carryover.
