DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel-type filler receiver for placing a filler installed inside a cooling tower.

[0002]

2. Description of the Related Art Conventionally, a cooling tower has been used to circulate and use hot water discharged from various facilities in a factory, a cooling and heating device in a building, and the like. A filler is provided in the cooling tower, and the hot water is cooled by contacting the cooling airflow in the filler, and is returned to the cooling / heating device or the like again.

FIG. 3 is a cross-sectional view of a portion (filler mounting structure) of a conventional cooling tower where a filler is installed. In this cooling tower, as shown in the figure, two beams 22 and 23, which are H-shaped in cross section and are held in a direction perpendicular to the paper surface, at predetermined heights of the pillars 20 and 21, and parallel to the paper surface. A beam 24 and a beam 25 (not shown) are attached. A plurality of channels (channel steel) 26 are passed over these two beams 24 and 25, and a filler 27 for bringing hot water into contact with a cooling airflow is placed on these channels 26. Have been. The airflow passes through the filler 27 in the direction indicated by the arrow 30. An eliminator guide 29 holding an eliminator 28 for removing mist accompanying the airflow 30 is attached to the beam 22 on the downstream side of the airflow. Further, on the lower surface on the upstream side of the beams 24 and 25, a fall prevention member 31 for preventing the lower filler 27 from falling down is attached.

[0004]

In such a conventional structure, the beams 22 to 25 must be sequentially mounted at predetermined heights of the columns 20 and 21, and these beams 22 to 25 must be mounted. In addition, it is necessary to attach the eliminator guide 29 to the beam 22 on the downstream side of the air flow, and to attach the fall prevention member 31. In addition, a scaffold is required to perform such an operation, and an operation of assembling the scaffold is also required. Since these operations need to be performed for all portions of the cooling tower where the filler is provided, the amount of operation is enormous.

Further, in the conventional structure, since the filler 27 is placed on the channel 26, the hot water which has uniformly descended in the filler 27 is disturbed by the channel 26 and becomes uneven. Therefore, the cooling efficiency of the hot water decreases.

[0006] Further, since there is nothing to define the position of the filler 27, the position of the filler 27 on the channel 26 cannot be determined. If the position of the filler 27 on the channel 26 is improper, a gap is formed between the adjacent fillers 27, which serves as a short path of the cooling air flow and reduces the cooling efficiency of the hot water.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a support structure for a filler which can be constructed with a small amount of work so that hot water descending in the filler can be obtained. It is an object of the present invention to provide a panel-type filler receiving member which does not make the flow uneven and can define the position of the filler.

[0008]

SUMMARY OF THE INVENTION A panel-type filler receiver according to the present invention is a panel-type filler receiver which is installed in a cooling tower and on which a filler for bringing hot water into contact with a cooling airflow is placed. (A) a panel portion on which the filler is placed, and (B) a downstream end of the airflow in the panel portion,
And an eliminator guide on which an eliminator for removing a mist accompanying the airflow after passing the filler is mounted.

[0009] Further, it is possible to add a structure in which the upper surface of the panel portion is in a net shape.

[0010] Further, a structure may be added in which a fall-preventing member for preventing the filler located at the lower stage from falling down is attached to the lower surface of the upstream end of the airflow in the panel portion.

Further, a configuration may be added in which a positioning member for defining a position of the filler placed on the panel portion is attached to an upper surface of an upstream end of the airflow in the panel portion. it can.

Become.

Further, in the panel-type filler receiving device of the present invention, since the upper surface of the panel portion can be formed in a net shape, the flow of hot water flowing down the filler does not become uneven. Further, since the upper surface of the panel portion formed in a net shape can be used as a scaffold, it is not necessary to separately assemble a scaffold for constructing the filler mounting structure.

Further, in the panel-type filler receiving device of the present invention, a fall-preventing member is attached to the lower surface of the upstream end of the airflow in the panel portion, so that the filler-mounting structure is constructed. The operation of attaching the stop member can be omitted, and the amount of operation can be further reduced. In addition, by disposing a filler positioning member on the upper surface of the upstream end of the airflow in the panel portion, it is possible to prevent the displacement of the filler placed on the panel portion.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a panel-type filler receiver according to one embodiment of the present invention. The panel-type filler receiver of this embodiment has a panel portion 1, and the panel portion 1 has beams 4 and 5. The eliminator guide 2 is attached to one end of the beams 4 and 5, and the fall prevention member 6 and the positioning member 7 are attached to the other ends of the beams 4 and 5. A wire mesh 3 is stretched on the upper surface between the beams 4 and 5. The eliminator guide 2 is made of an H-shaped steel, and the fall prevention member 6 and the positioning member 7 are each made of an angle (angle iron). Of these members 6 and 7, the fall prevention member 6 is attached to the lower surface of the panel portion 1, and the positioning member 7 is attached to the upper surface of the panel portion 1. In this embodiment, the eliminator guide 2 also constitutes the panel portion 1, and the fall prevention member 6 and the positioning member 7 also constitute the panel portion 1.
That is, the panel portion 1, the fall prevention member 6, and the positioning member 7
Also functions as a beam in a direction orthogonal to the beams 4 and 5 of the panel unit 1.

FIG. 2 is a cross-sectional view of a filler support structure in which the panel-type filler receiver of FIG. 1 is installed in a cooling tower. The construction of the filler support structure using the panel-type filler receiver of this embodiment is performed as follows. First, the eliminator guide 2 and the ends of the beams 4 and 5 on the side where the fall prevention member 6 and the positioning member 7 are mounted are mounted at predetermined heights of the columns 20 and 21. The attachment to the columns 20 and 21 is performed by bolts, welding, rivets, or the like. Since the cooling airflow is supplied in the direction shown by the arrow 30, the eliminator guide 2 on which the eliminator for removing the mist is placed is installed downstream of the airflow, and the fall prevention member 6 and the positioning member 7 is installed so as to be on the upstream side of this air flow.

On the wire net 3 on the upper surface of the panel section 1, a filler 27 for bringing hot water into contact with a cooling airflow is provided.
The placement of the filler 27 is performed as follows. That is,
The lower ridge line of the filler 27 on the support column 21 side is the positioning member 7.
And at the same time, the upper ridgeline of the filler 27 on the support column 21 side contacts the bent portion of the fall prevention member 6 attached to the lower surface of the upper panel type filler receiver. Is placed. This defines the position of the filler 27.

After the filler 27 is installed in this way, the eliminator 28 for removing the mist accompanying the airflow is placed on the eliminator guide 2, and the construction of the filler placement structure is completed.

In the panel-type filler receiving device of the present embodiment, a portion on which the filler 27 is placed is constituted by the panel portion 1 and the eliminator guide 2 is attached to this panel portion 1, so that a filler placing structure is constructed. It is possible to greatly reduce the amount of work required to perform the operation. Further, in the panel-type filler receiving device of the present embodiment, the falling-preventing member 6 for preventing the filling material 27 from falling is attached to the lower surface of the panel portion 1, so that the falling-preventing member can be used when constructing the filling material mounting structure. The mounting operation can be omitted, and the amount of operation can be further reduced. When the panel-type filler receiving device of this embodiment is used, the construction of the filler placing structure can be completed in about one third of the number of construction days as compared with the case of the conventional construction method.

In this embodiment, since the wire mesh 3 is provided on the upper surface of the panel section 1, the flow of the hot water flowing down the filler 27 may be uneven as in the case of using a conventional channel. Absent. Further, since the wire netting 3 can be used as a scaffold, it is not necessary to separately provide a scaffold for constructing the filler mounting structure.

Further, since the positioning member 7 is attached to the panel section 1, it is possible to prevent the filler placed on the panel section 1 from being displaced. By this action of preventing displacement, it is possible to prevent a gap from being generated between the adjacent fillers 27, and it is possible to prevent a decrease in cooling efficiency of hot water.

In this embodiment, the case where a wire net is provided on the panel section 1 has been described. However, the present invention is not limited to this, and any net-shaped wire can be used.
Further, although the H-section steel is used as the eliminator guide 2, the present invention is not limited to this.
Any member can be used as long as it has a cross-sectional structure capable of mounting. Similarly, in this embodiment, an angle is used as the fall prevention member 6 and the positioning member 7, but a member having another bent portion may be used. Further, in this embodiment, the case where the eliminator guide 2, the fall prevention member 6, and the positioning member 7 also function as beams of the panel portion 1 has been described, but a configuration in which beams are provided separately from these may be employed. it can.
