Description

[0001]
[Field of the Invention]
The present invention particularly relates to a white smoke prevention type cooling tower suitable for use in large buildings such as leisure buildings, computer center buildings, airport buildings, heliport buildings, etc. The present invention relates to a white smoke prevention type cooling tower filler that constitutes the heat exchange section.
[0002]
[Prior art]
The cooling tower forms part of a building air conditioning system, a refrigeration system, etc., and generally, as shown in FIG. 1, warm water (circulated hot water) A circulated in the system is heated from a hot water tank 2 to a heat exchange unit. 3, while flowing the air in a direction perpendicular to the flow direction of the water in the heat exchanging unit 3, the hot water is cooled by heat exchange by direct contact between the air and the hot water, and the cooling water B is again supplied to the system. It is configured to circulate in.
[0003]
However, since air absorbs moisture when it flows through the heat exchanging section 3, if the temperature of the outside air is low or the humidity is high, it will be oversaturated when it is released from the cooling tower to the outside air, generating fog. And white smoke is produced. This white smoke may be mistaken for the emission of fire smoke and harmful substances, and may develop into a major problem from such a minor misunderstanding, especially in large-scale industrial areas such as power sales, blast furnaces, and nuclear power generation. There is. In addition, it was pointed out that in winter the trees in the surrounding forest are frozen and cause the trees to wither.
[0004]
Therefore, conventionally, as a white smoke prevention type cooling tower that does not generate white smoke, for example, as shown in FIG. 6, a filler (structure formed by laminating heat exchange plates) 50 disposed in the heat exchange unit 3 is heated. Between the wet spaces 51, 51... In which warm water is made to flow down on the surface of the exchange plate and water films are formed on the surfaces of both side walls, the flow of the warm water is blocked by the caps 53 to form a waterless space. ··································································································································································· A structure for preventing the above has been developed.
[0005]
On the other hand, not only cooling towers used in large industrial areas such as power sales business, blast furnaces, and nuclear power generation, but also cooling towers used in general buildings along with recent high-tech and intelligent in the office, Increasing the size, in other words, increasing the cooling capacity, has been demanded. Against the background of such demand, a technology for constructing a large filler by stacking filler blocks in a multistage manner is disclosed.
[0006]
As a stacked structure of the filler blocks, for example, as shown in FIG. 6, a cap 53 is disposed at the upper end opening of each stage of the dry space 52, while the bottom lid 54 is narrowed at the lower end. The plate piece portion 56 projecting downward from the bottom lid portion 54 of the upper filler block 55 and the plate piece portion 57 projecting upward from the cap 53 of the lower filler block 55 are fixed by welding. Connected and stacked,
[0007]
As shown in FIG. 7, a bifurcated engagement portion 65 opened downward is formed at the lower end edge of the heat exchange plate 64 constituting the dry space 63 of the upper filler block 61, and the lower filler block 62 A structure in which the upper edge of the heat exchange plate 64 constituting the dry space 63 abuts on the lower surface of the bifurcated engagement edge 65 and is supported and fixed by its own weight of the upper filler block 61.
As shown in FIG. 8, the lower end of the heat exchange plate 74 constituting the dry space 73 of the upper filler block 71 and the upper end of the heat exchange plate 74 constituting the dry space 73 of the lower filler block 72. And the like with a connecting member 75 having a bifurcated engagement edge portion 75a opened upward at the upper end portion and a bifurcated engagement edge portion 75b opened downward at the lower end portion. Have been conceived.
[0009]
[Problems to be solved by the invention]
However, in the stacked structure as shown in FIG. 6, it is necessary to assemble the entire filler in advance by welding the filler blocks at each stage in the factory, and carry out the work of assembling to the transport tower and the cooling tower as the entire filler. Because of this, there was a problem that it took a lot of effort.
Moreover, since the stacking structure as shown in FIGS. 7 and 8 fixes the engagement by the weight of the upper filler block, the sealability of each connecting portion is insufficient, and the wet space portion into the dry space portion. There was a risk that warm water could infiltrate and the white smoke prevention effect would decrease, and the filler could be displaced or collapsed by an earthquake or the like.
Furthermore, in any of the stacked structures shown in FIGS. 6 to 8, a manufacturing error occurs in the filling plate, or the filling material sinks and deforms during long-term use due to the weight of water flowing down the wet space. When it occurs, it is impossible to absorb these errors and deformations, and it is impossible to secure the absence of water in the dry space, and there is a possibility that the white smoke prevention effect may be reduced.
[0010]
Therefore, in order to solve the above problems, the present invention can easily carry the packing material and assemble it to the cooling tower in the packing material constituted by stacking the packing material blocks in multiple stages, and can be displaced by an earthquake or the like. In addition, it is possible to ensure a water-free space when necessary, and to absorb a manufacturing error or deformation caused by subsidence, and a white material incorporating the same. It is intended to provide a smoke-proof cooling tower.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides:
Each stage of the filler block is fixed to a fixed structure portion such as a cooling tower body, and a plurality of heat exchange plates are connected so as to face each other at an appropriate interval. In the white smoke prevention type cooling tower filler, which is formed by stacking the packing blocks formed by partitioning the dry space section in multiple stages, the packing blocks in each stage are fixed to a fixed structure part such as the cooling tower body. has a fixing groove which is upwardly open to the piece upper section, the anchoring groove of the upper connecting piece comprising a mating receiving portion formed by the lower opening to the piece lower portion, the dry space of the upper filler block The fixing groove of the lower connecting piece is fixed to the lower end portion of the formed heat exchange plate, has an insertion piece portion at the upper end portion of the piece, and has a fixing groove opened downward at the lower end portion of the piece. At the upper end of the heat exchange plate forming the dry space of the block The insertion piece portion of the intermediate connection piece having an insertion piece portion at the upper end portion of the piece and having a fitting reception portion opened downward at the lower end portion of the piece is fitted into the fitting reception portion of the upper connection piece. Inserted into the part and connected in a telescopic manner, and inserted into the fitting receiving part of the intermediate connection piece to insert and insert the insertion piece part of the lower connection piece so as to extend and contract. A white smoke prevention type cooling tower filler was constructed in which the space portion communicated vertically.
The “fixed structure portion such as the cooling tower body” means a structural member in a fixed state such as the cooling tower body or the frame structure of the cooling tower.
[0012]
In the packing material for the white smoke prevention type cooling tower having the above-described configuration, instead of using the three-member connecting member as described above, a lower opening is formed at the lower end of the dry space forming heat exchange plate of the upper packing block. The insertion receiving portion is provided, the insertion piece is projected from the upper end of the dry space forming heat exchange plate of the lower filler block, the insertion piece is provided at the upper end of the piece, and the lower end of the piece The intermediate connecting piece is inserted into the fitting receiving portion at the lower end portion of the heat exchange plate and is connected to be stretchable by inserting the insertion piece portion of the intermediate connecting piece having a fitting receiving portion opened downward.

There is no. Furthermore, in the stage before assembling to the cooling tower, it can be transported for each filler block, and when assembling to the cooling tower, after fixing each stage of the filler block, the upper and lower stage filler blocks are connected by a connecting member. It can be assembled very easily. In addition, it is very easy to repair and clean since each filler block can be removed by removing the connecting member. Furthermore, in the connection structure between each filler block, since it is a structure which inserts and connects the insertion piece part of a lower member in the fitting receiving part which all connection parts open downward, from a wet space part There is no risk of water entering the dry space, and a water-free space can be ensured reliably. Furthermore, since each connection part is connected so that expansion-contraction is possible, the deformation | transformation by a manufacturing error, sinking, etc. can be absorbed.
[0014]
The said structure WHEREIN: It is preferable to provide an expansion-contraction space part between the insertion piece part front-end | tip part and the back end part in a fitting receiving part. Manufacturing errors and the like can be absorbed by the stretchable space portion, and a waterless space can be secured more reliably. In addition, a plurality of V grooves extending in the longitudinal direction are provided on both sides of the intermediate connection piece or the lower connection piece or the insertion piece portion of the heat exchange plate in the vertical direction, and the V groove and the opening of the fitting receiving portion Can also be configured to engage. If it forms in this way, each connection piece can be connected correctly and easily.
[0015]
The filler having the above configuration can be incorporated in the heat exchange section of the cooling tower to constitute a white smoke prevention type cooling tower. At this time, the dry space portion can be appropriately switched to the wet space portion.For example, in summer when white smoke does not occur, the heat exchange area is increased by switching the dry space portion to the wet space portion. Since the cooling capacity of the cooling tower can be increased, the filler and the cooling tower can be made compact.

For example, a lid that can be opened and closed is disposed at the upper end opening of the dry space 15 of the uppermost filler block 11, and the lid is closed in the winter or when the humidity is high and white smoke is generated. 15 can be used as an anhydrous space, and under conditions where white smoke does not occur, such as in summer, the lid can be opened and water can flow into the dry space 15 to form a wet space. In addition, a watering nozzle that can be switched above the dry space 15 of the uppermost filler block 11 may be provided so that water can be sprayed into the dry space 15 as necessary. If the dry space 15 can be switched to the wet space as necessary, the contact area between the air and water, that is, the heat exchange area can be increased, so that the cooling capacity of the entire cooling tower can be increased. Thus, the cooling tower and the cooling tower filler can be made compact.
In addition to the above-described means, the means for configuring the dry space portion 15 to be a dry / wet switching type is arbitrary as long as it can switch between water spraying to the dry space portion 15 of the uppermost filler block 11 and water spray blocking. Can be adopted.
[0033]
For example, the filler 10 having the above-described configuration can be assembled into the heat exchange unit 3 of the cooling tower 1 as shown in FIG. 1 to form a white smoke prevention type cooling tower. The assembly to the heat exchanging unit 3 is performed by placing the filler blocks 11, 11... On each stage on the support support members 16, 16. Since it only has to be connected by the member 20, even the large filler 10 can be easily assembled.
[0034]
【The invention's effect】
As described above, since the filler according to the present invention is configured by stacking filler blocks in a multistage manner, a large filler, that is, a large heat exchanging portion can be configured. In addition, by devising the structure of the connecting part that connects the upper and lower filler blocks, water does not enter the dry space part from the wet space part, and generation of white smoke can be reliably prevented, Even if the filler sinks during use for many years, it can be absorbed, and it has a strong stacked structure that does not slip or collapse due to an earthquake etc., so it has strong cooling It is possible to provide a cooling tower that is suitable for use in a large-scale industrial area such as a power sales business, a blast furnace, and a nuclear power generation that requires a capability and that particularly hates generation of white smoke.
