Abstract

PURPOSE:To facilitate the replacement of a filler by making it possible to take out the filler from the void formed by removing downwardly a case mounted within a casing and having at least the same size as a unit filling member. CONSTITUTION:A case 10 is provided in the suitable place of a filler 3, for example, at the central part thereof. The case 10 is formed at least in the same size as a unit filling member 3a. A support frame 14 for the case is detachably mounted on a support frame 13 for the unit filling member. When the filler 3 is replaced, a void is defined at the central part of filler 3 by removing the support frame 14 and drawing out the case 10 downwardly, and then the respective unit filling members 3a are drawn in order toward the void side to be drawn out of the void downwardly and taken outwardly therefrom. According to this constitution, the filler can be simply replaced without the need for the conventional demounting of a water spray mechanism 4, a suction fan 6 and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a counterflow type cooling tower, and particularly to a counterflow type cooling tower in which a filler is detachable.

[Conventional technology]

Generally, cross-flow type cooling towers have a structure in which outside air is taken in from the side of the filling material, so that the filling material can be relatively easily loaded and removed from the air intake port. In a counterflow type cooling tower, outside air is taken in from below the filling material, so the sides of the filling material are covered by the inside of the cooling tower casing. The outline is shown in FIG. The counterflow type cooling tower 50 houses a filler 52 in a casing 51, has a water sprinkling mechanism 53 above it, a steam/moisture utilization eliminator 64 above it, and has a suction fan 55 attached to the upper opening of the casing. .

There is also a method of providing a frontage in the casing 51 as a means for taking out the filler. However, there are problems such as the complicated structure, which impairs the aesthetic appearance, and the possibility of water leakage. For this reason, when replacing the filling material, a method is generally adopted in which the top cover, suction fan, water sprinkling mechanism, and eliminator of the casing are removed. Alternatively, when assembling the casing, the filling material is inserted, which requires skill and effort.

[Problem to be solved by the invention]

However, in large-sized cooling towers, the suction fan, water spray mechanism, etc. weigh considerably and require the use of a crane, etc. to assemble them, and there are problems such as replacing the filling material is extremely time-consuming. .

[Means to solve the problem]

In view of this, the present invention aims to easily load and unload the filling material without removing the suction fan, etc. The present invention is characterized in that the filling material is composed of a large number of unit filling members, A casing having at least the size of a unit filling member is loaded into the cooling tower casing at an appropriate position of the filling material, and the casing is attached to be removable downward, and each unit filling member fills a gap formed by removing the casing. The reason is that it can be taken out further down.

[For production]

A gap is created by removing the casing downward, and using this gap, the unit filling members are sequentially taken out downward.
Alternatively, new unit filling members can be sequentially inserted.

〔Example〕

1 to 3 show a first embodiment. A counterflow type cooling tower (hereinafter simply referred to as a cooling tower) l has a filling material 3 loaded into a casing 2 in the same way as the conventional structure (Fig. 7), and above which a water sprinkling mechanism 4 and an eliminator 5 for air/water separation are arranged. A suction fan 6 is attached to the upper opening of the casing. Further, an outside air intake lower is opened below the filler storage in the casing 2, and a water storage tank 8 is provided below. Reference numeral 9 denotes a louver that is detachably attached to the outside air intake lower.

The filling material 3 is made up of a large number of unit filling materials 3a, 3a, .

The unit filling member 3a has an appropriate shape, and in this embodiment, the long side is a plane rectangle with the width inside the casing 2, and the casing 10 has at least the same shape as the unit filling member 3a. It consists of left and right side walls 11 and a top plate 12, and is airtightly inserted between unit filling members.

In the figure, 13 is a support frame for the unit filling member 3a, and 14 is a housing support frame, and the housing support frame 14 is detachably attached to the unit filling member support frame 13.

In the above configuration, when replacing the filler 3, the louver 9, which is an example, is removed, the operator enters inside, removes the support frame 14, and pulls out the housing 10 downward. As a result, a gap is formed in the center, and since the size of the housing lO is at least the same as that of the unit filling member 3a, the unit filling material can be received, and the unit filling material can be successively drawn toward the gap and pulled out downward. Transport outside.

When loading the unit filling member 3a, the above operation may be performed in reverse.

Next, FIGS. 4 to 6 show a second embodiment.

In this embodiment, the present invention is applied to a cooling tower that is even larger than the previous example, and the filling material 21 of this cooling tower 20 is divided into a number of unit filling members 21a in the front, back, left, and right directions, and a housing 22 is placed in an appropriate place, for example, in the center. The housing 22 includes at least the unit filling member 21.
Let the size be a. This housing 22 also has a side wall 2 like the previous example.
3 and a top plate 24, and a support frame 25, and the support frame 25 is detachably attached to the unit filling member support frame 26. The structure of the pond is the same as that of the previous example, and the same parts are given the same reference numerals and the explanation will be omitted.

When replacing the unit filling member 21a, the housing 22 is taken out downward as in the previous example, thereby forming a gap, and the unit filling member 21a is successively taken out downward using this gap. is the same as the previous example, so the explanation will be omitted.

Although the casings 10 and 22 of the first and second embodiments are both box-shaped with side plates and a top plate, they may be constructed of the same member as the unit filling member 3a or 21a. . With this structure, it is possible to prevent the number of heat exchange parts from decreasing due to the installation of the casing.

In this case, it is preferable that the housing has a structure in which the filling material is surrounded by a side wall. This prevents the unit filling member from deforming and combining with the housing during long-term use,
This has the advantage that the casing can be easily taken out.

In addition, inspection and maintenance of the water spray nozzles can be easily carried out using the space from which the casings 10 and 22 are removed.

〔Effect of the invention〕

According to the present invention, the filling material is composed of a large number of unit filling members, and a casing having at least the same size as the unit filling members is inserted, and this casing is taken out downward. A void is formed by this, and therefore each unit filling member can be taken out and inserted in sequence, and the filling material can be easily replaced without requiring removal of the conventional water sprinkling mechanism, suction fan, etc.
