Description

  The present invention relates to a cooling tower assembly unit for use in the construction and assembly of a cooling tower.

  Conventionally, a cooling tower is used in an air conditioning facility, a production facility, or the like as a device that cools circulating water by exchanging heat.

  One of the typical cooling tower systems is the cross flow system. This type of cooling tower includes, for example, an exhaust passage extending in the vertical direction, a filler arranged so as to surround the exhaust passage, a louver (vent) disposed on the outer surface of the filler, and an exhaust passage. A cold water tank disposed below, a blower disposed above the exhaust passage, and a hot water pipe disposed above the filler. When the cooling tower is driven, hot water (circulated water) is sprinkled from the hot water pipe to the lower filler. By driving the blower, exhaust of air in the exhaust passage is promoted, and outside air flows into the filler through the louver. As a result, the outside air is brought into contact with the circulating water so as to be orthogonal, and heat is exchanged with the circulating water. The outside air after heat exchange is exhausted outside through the exhaust passage. On the other hand, the cold water after heat exchange is stored in a cold water tank and reused for a desired application.

  As a construction method for constructing a cooling tower having such a configuration, for example, as shown in Patent Document 1 or 2, a cooling tower assembly unit in which a filler is contained in a frame having a hexahedral internal space in a factory is used. There is a construction method that prepares in advance, loads the cooling tower assembly unit on a truck or the like, transports it, and stacks the plurality of cooling tower assembly units at the installation site to arrange the fillers. By constructing and assembling the cooling tower using such a cooling tower assembly unit, it is expected that the construction time of the cooling tower will be shortened and the construction efficiency will be improved even if the size of the cooling tower is relatively large. can do.

  In the cooling tower assembly unit, when the filler is disposed in the internal space of the frame, a gap may be set between the frame and the filler. For this reason, when the cooling tower assembly unit is transported or when the cooling tower is assembled and assembled, an external force such as vibration or shaking is transmitted to the cooling tower assembly unit, or the cooling tower assembly unit is tilted. There is a risk that the filler may be displaced in the internal space. When such misalignment of the filler occurs, it becomes difficult to stack the filler at the correct position when the cooling tower is constructed.

  Such a problem may also occur in a cooling tower other than the cross flow system.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a cooling tower assembly unit that can be expected to exhibit excellent cooling efficiency by preventing the displacement of the filler inside the frame. And

  In order to solve the above problem, an assembly unit for a cooling tower according to an aspect of the present invention includes a frame having a plurality of columns extending in the vertical direction and having a hexahedral internal space formed therein, In the internal space of the frame body, one or more fillers that are arranged in the internal space and exchange heat with the gas and water circulated inside, and at both ends of one side of the frame body among the plurality of pillars. A supporting member that extends over each side of the first pillar and the second pillar that are positioned and extends inward of the frame, wherein the supporting member that extends inward of the frame is It has the structure which has contact | abutted with the side surface of the filler.

  In the cooling tower assembly unit according to the above aspect of the present invention, in the internal space of the frame, among the plurality of columns, the cooling column is laid over each side of the first column and the second column located at both ends of one side of the frame. And a support member extending inward of the frame. Further, a support member extending inward of the frame is in contact with the side surface of the filler.

  As a result, even when the cooling tower assembly unit is transported or the cooling tower is constructed and assembled, vibrations are transmitted to the frame body from the outside or the frame body is tilted. The support member supports the filler by abutting the side surface of the filler between the side portion and the side of the filler, so that the filler supported by the support member is placed on the first column and the second column side. It is possible to prevent the positional deviation from occurring.

  As a result, according to the cooling tower assembly unit of one aspect of the present invention, it is possible to provide a cooling tower assembly unit that can be expected to exhibit excellent cooling efficiency by preventing the displacement of the filler inside the frame. .

  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
FIG. 1 shows a schematic configuration of a cooling tower 100 according to the first embodiment. The cooling tower 100 includes a cold water tank 101, an assembly unit group 102 disposed so as to surround the periphery of the exhaust passage 107 extending in the vertical direction above the cold water tank 101, and a horizontal direction over each of the assembly unit groups 102. The fan deck 103 disposed, the hot water supply pipe 104 extending along the upper surface of the fan deck 103, the blower 106 disposed at a position overlapping the exhaust passage 107 on the upper surface of the fan deck 103, and the blower 106 And a connected electric motor 105. The assembly unit group 102 is formed by stacking a plurality of cooling tower assembly units 1 (hereinafter referred to as “assembly units 1”) having a configuration described later in the vertical direction.

  Note that a plurality of frame members 108 for supporting each of the above-described components are disposed inside the cooling tower 100.

  2 and 3 show the overall configuration of the assembly unit 1. The assembly unit 1 includes a frame 2 having a plurality of beams (long beam 2a and short beam 2b) and a plurality of pillars 2c arranged so as to connect each corner of the hexahedron, and an internal space of the frame 2 One or more fillers 3 accommodated in S and stacked in the vertical direction, louvers 5 and support members 6 arranged in a plurality of pillars 2c, and support members 6 in the internal space S of the frame 2 And a supported eliminator 7.

  The frame 2 includes a plurality of long beams 2a and short beams 2b that extend in the horizontal direction, and a plurality of columns 2c that extend in the vertical direction (here, the first column 2ca, the second column 2cb, The three pillars 2cc and the fourth pillar 2cd) are connected to each other and have a hexahedral internal space S. The portions corresponding to the side surfaces, the upper surface, and the lower surface of the frame 2 are reinforced using a plurality of braces (diagonal materials) 2e and 2f. Below the frame 2, a plurality of plate-like support members 2g for placing the filler 3 and a plate 2h as a water return plate for returning the water generated by the eliminator 7 to the filler 3 side are spaced apart from each other. In parallel. Above the frame body 2, a plurality of plate-like pressing members 2 d for pressing the filler 3 from above are arranged in parallel at intervals. As an example, the long beam 2a and the short beam 2b are each configured using channel steel, and the plurality of columns 2c are configured using a steel pipe as an example. In the internal space S, the support member 6 is constructed over each side part of the 1st pillar 2ca and the 2nd pillar 2cb which are located in the both ends of the one side of the frame 2 among the some pillars 2c. Further, on the other side of the frame body 2 located on the opposite side of the first column 2ca and the second column 2cb, the louver 5 extends over each side of the third column 2cc and the fourth column 2cd located at both ends of the other side. Is arranged.

  In addition, although the internal space S in Embodiment 1 is made into a rectangular parallelepiped shape as an example, it is not limited to this, For example, you may comprise as a cube or a parallelepiped. For this reason, the plurality of pillars 2c are not limited to a configuration that strictly extends in the vertical direction, and may be configured to extend in the vertical direction while being slightly inclined with respect to the vertical direction.

  As an example, the filler 3 is in a state in which a plurality of resin plates (not shown) having a concavo-convex surface are set up, and with a space between the plates, a part of the concave and convex portions of each opposing plate is formed. They are fitted and juxtaposed and have a rectangular parallelepiped appearance as a whole. When the cooling tower 100 is driven, gas and water are circulated inside and outside to exchange heat between the gas and the water. Specifically, a water film of circulating water used as the water is formed on the surface of each plate, and the circulating water is brought into contact with the gas (outside air) flowing from the horizontal direction between the plates, thereby circulating the outside air and the circulation. Heat exchange with water. As an example, two fillers 3 are provided at the lower stage in the internal space S, and the two fillers 3 are stacked in parallel on the upper stage, and are arranged over a total of four. In the assembly unit 1, the third pillar 2 cc and the fourth pillar 2 cd are more disposed in the internal space S than the first pillar 2 ca and the second pillar 2 cb due to the arrangement of the eliminators 7 and the fillers 3 in the internal space S. Each filler 3 is unevenly distributed in the position of the side.

  The shape of the filler 3 is not limited to a rectangular parallelepiped shape, and may be any shape of a cube, a parallelepiped, or other polyhedrons.

  The louver (suction grill) 5 uses a plurality of strip-shaped plate bodies 5a, and the plate bodies 5a are arranged in parallel with a horizontal direction as a longitudinal direction with a gap in the vertical direction. The louver 5 is disposed outside the frame body 2 in order to introduce outside air into the internal space S across the side portions of the third pillar 2cc and the fourth pillar 2cd. Specifically, as shown in FIG. 3, the assembly unit 1 is designed so that outside air is introduced into the internal space S through gaps (openings 4) that exist between the plate bodies 5 a of the louver 5. The louver 5 serves to prevent foreign matters approaching from the outside from entering the assembly unit 1 and also preventing circulating water flowing through the filler 3 from splashing outside. In order to exhibit such functions, the louver 5 is arranged in the assembly unit group 102 so as to face the outside in the cooling tower 100. The louver 5 can be configured using a material such as FRP, for example.

  The eliminator (droplet removal plate) 7 is formed by arranging a plurality of resin wave-like sheet bodies in parallel with a space therebetween, and has a thin plate-like appearance as a whole. When the cooling tower 100 is driven, a part of the moisture in the outside air that flows out from the filler 3 to the side that is the downstream side of the airflow is removed. In the assembly unit 1, the two eliminators 7 are opposed to the side surfaces of the filler 3 between the side surfaces of the filler 3 and the side portions of the first column 2 ca and the second column 2 cb in the internal space S. In a standing state, the support members 6 are arranged side by side in the vertical direction. At this time, the eliminator 7 is disposed so as to be slightly inclined from above to below the frame 2. The lower end of the upper eliminator 7 is placed on the water return plate 6 b of the support member 6, and the lower end of the lower eliminator 7 is placed on the upper surface of the plate 2 h in the frame 2. In the cooling tower 100, the eliminator 7 is arranged so as to face the exhaust passage 107 in the assembly unit group 102. In addition, the eliminator 7 is not limited to the structure arrange | positioned so that it may incline, For example, you may arrange | position upright in the perpendicular direction.

  As shown in FIG. 4, the support member 6 includes a plate-like attachment portion 6 a arranged upright in the vertical direction, a water return plate portion 6 b connected to the attachment portion 6 a and extending in a substantially horizontal direction, and a water return plate portion. It has a plurality of projecting portions 6 c erected on the upper surface and the lower surface of 6 b, and an end 6 f on the inner side of the frame body 2. The end portion 6f is a portion disposed so as to face the side surface of the filler 3 and has a contact portion 6d that contacts the side surface of the filler 3 by surface contact. The support member 6 is used as a member that supports the filler 3 from its side surface.

  The abutting portion 6d is not limited to a configuration that directly abuts against the side surface of the filler 3. Therefore, for example, the contact portion 6d may indirectly contact the side surface of the filler 3 via a separate body such as a sheet body or a plate body. Such a configuration is also included in the present invention in the configuration in which the support member is in contact with the side surface of the filler.

  The mounting portion 6a is a part for laying the support member 6 over each side of the first column 2ca and the second column 2cb, and one surface is in surface contact with each side of the first column 2ca and the second column 2cb. In this state, the first pillar 2ca and the second pillar 2cb are connected to the respective side portions by fasteners using a plurality of bolts B and nuts (not shown). Thereby, the supporting member 6 is fixed in a cantilever state with respect to the first pillar 2ca and the second pillar 2cb. In addition, the connection method of the attaching part 6a, the 1st pillar 2ca, and the 2nd pillar 2cb is not limited to the said fastening method using the volt | bolt B and a nut, In addition to the fastening method fixed only using a screw, welding etc. A connection method may be used. In the first embodiment, the attachment portion 6a is formed in a long plate shape extending from the first column 2ca to the second column 2cb, whereby the attachment portion 6a is continuous with the water return plate portion 6b, and the support member 6 is It also serves as a wall portion standing outward from the portion (end portion 6 f) that contacts the side surface of the filler 3.

  6 d of contact parts are long plate shape extended in the longitudinal direction of the short beam 2b in the frame 2, and are extended and formed below from the edge part of the water return board part 6b. The contact portion 6d has a flat outer surface. The width W1 of the abutting portion 6d is set so that the abutting portion 6d can abut on the side surface of each filler 3 stacked in the vertical direction by surface contact with a certain area. In the assembly unit 1, the attachment portion 6 a is attached to each side portion of the first pillar 2 ca and the second pillar 2 cb at a predetermined height, so that the contact portion 6 d has a side surface and a lower portion of the lower end portion of the upper filler 3. It arrange | positions so that it may contact and contact | abut with the side surface of the upper end part of the side filler 3 (refer FIG. 5).

  The water return plate portion 6b has a flat plate shape and has an upper surface that extends inward of the frame 2 and extends from the first column 2ca to the second column 2cb. The upper surface of the water return plate portion 6 b is inclined so as to form a downward gradient toward the inside of the frame body 2. The upper and lower surfaces of the water return plate portion 6b have a rectangular flat surface when viewed in plan. The water return plate portion 6b serves to transfer a part of the circulating water that has flowed out from each filler 3 to the side that is downstream of the air flow when the cooling tower 100 is driven, and return it to each filler 3 side. . Here, as shown in FIG. 2, the water return plate 6 b is located above the lower end of the upper filler 3. On the upper surface and the lower surface of the water return plate portion 6b, one or more (here, a plurality as an example) rib-like protruding portions 6c are erected with a gap 6e along the longitudinal direction of the short beam 2b. As shown in FIG. 4, the shortest distance W2 between the protrusion 6c and the attachment portion 6a in the water return plate portion 6b is set according to the thickness of the eliminator 7 along the long beam 2a. As a result, the lower end portion of the eliminator 7 located above the eliminator 7 arranged in the vertical direction in the internal space S of the frame body 2 is placed on the upper surface of the water return plate portion 6b. The upper end of the eliminator 7 located below is placed on the lower surface of 6b. At this time, the lower end portion of the eliminator 7 positioned above is sandwiched between the protruding portion 6c erected on the upper surface of the water return plate portion 6b and each side portion of the first column 2ca and the second column 2cb. The upper end portion of the eliminator 7 positioned below is sandwiched between the protruding portion 6c erected on the lower surface of the water return plate portion 6b and the side portions of the first column 2ca and the second column 2cb. Is positioned. As described above, the end portions of the eliminators 7 are positioned between the side portions of the first pillar 2ca and the second pillar 2cb and the protrusions 6c, thereby positioning the two eliminators 7 arranged in the vertical direction. Are supported by the support members 6 in a state where the angle is raised. In addition, the shortest distance W3 between the protrusion part 6c and the filler 3 in the water return board part 6b can be adjusted suitably. In the first embodiment, the water return plate portion 6b and the contact portion 6d of the support member 6 are integrally formed by bending a plate body. For this reason, there exists an advantage which can produce the supporting member 6 at comparatively low cost. As with the contact portion 6d, the attachment portion 6a may be formed integrally with the water return plate portion 6b by bending the plate body.

  In the cooling tower 100 having the above configuration, hot water (circulated water) sent from the outside at the time of driving is sprinkled from the sprinkling nozzle 104a of the hot water supply pipe 104 toward the assembly unit group 102 below. At this time, the circulating water is sprayed over the entire upper surface of the assembly unit group 102 through the opening 103 a provided in the fan deck 103. The supply of hot water is not limited to the supply of the combination of the hot water supply pipe 104 and the watering nozzle 104a. For example, a hot water tank is installed, the watering nozzle 104a is installed at the lower part of the hot water tank, and water is supplied to the hot water tank. You may make it supply through the watering nozzle 104a provided in the lower part of the said warm water tank by supplying (storage).

  On the other hand, when the blower 106 is driven by the driving force of the electric motor 105, the air in the exhaust passage 107 is discharged to the outside as the fan of the blower 106 rotates. As a result, the inside of the exhaust passage 107 has a negative pressure, and outside air flows into the filler 3 in each assembly unit 1 of the assembly unit group 102 via the louver 5 provided on the outer periphery of the assembly unit group 102. At this time, the outside air flows into the filler 3 from the horizontal direction and exchanges heat by contacting with circulating water flowing downward by gravity along the surface of each plate constituting the filler 3. Through this heat exchange, the circulating water is cooled to become cold water. The cold water flows out from below through the filler 3. The cold water is stored in the cold water tank 101 through the opening 101a and then reused for a desired application through a pipe (not shown). The outside air that has flowed out of each filler 3 in the assembly unit group 102 comes into contact with the wavy sheet member constituting the eliminator 7 and is removed from the water. The outside air thus removed passes through the eliminator 7 and is exhausted to the outside from the exhaust passage 107 by the blower 106.

  Here, according to the assembly unit 1, the following various effects can be expected.

  First, when the assembly unit 1 is loaded on a truck or the like, or when the cooling tower 100 is constructed or assembled, external force such as vibration or shaking is transmitted to the assembly unit 1 or the first pillar 2ca and It is assumed that the assembly unit 1 is inclined in a direction in which the second column 2cb faces downward from the third column 2cc and the fourth column 2cd. In such a case, when the load of each filler 3 is applied to the support member 6, as shown in FIG. 5, the support member 6 has a mounting portion 6a fixed to the first column 2ca and the second column 2cb as a fulcrum, Each filler 3 is pushed back by the contact portion 6d, and each filler 3 is supported in a state where it is placed at the original position. Thereby, it can prevent effectively that each filler 3 supported with the support member 6 produces position shift toward the 1st pillar 2ca and 2nd pillar 2cb side. As a result, when the cooling tower 100 is constructed and assembled, the filler 3 of each assembly unit 1 can be disposed at a regular position in the assembly unit group 102, and therefore, excellent cooling efficiency can be expected as designed by the cooling tower 100. Is possible.

  In the assembly unit 1, as shown in FIGS. 2 and 3, each filler 3 is unevenly distributed in the vicinity of the third column 2cc and the fourth column 2cd along the longitudinal direction of the long beam 2a. Therefore, the gap existing between the third pillar 2cc and the fourth pillar 2cd and the side surface of the filler 3 is larger than the gap existing between the first pillar 2ca and the second pillar 2cb and the side surface of the filler 3. And very small. Therefore, it is considered that the possibility that the filler 3 is displaced in the inner space S toward the first pillar 2ca and the second pillar 2cb is low. Furthermore, the filler 3 is in contact with the support member 2g below the frame body 2 and is close to the pressing member 2d above. Therefore, in the assembly unit 1, by providing the support members 6 on the first pillar 2ca and the second pillar 2cb, it is possible to prevent the displacement of the filler 3 in both the vertical direction and the direction along the longitudinal direction of the long beam 2a. it is conceivable that.

  Secondly, in the assembly unit 1, the support member 6 has a water return plate portion 6 b having an upper surface and an attachment portion 6 a as a wall portion erected outward from the end portion 6 f. For this reason, when the cooling tower 100 is driven, as shown in FIG. 5, water generated in the upper eliminator 7 disposed on the upper surface of the water return plate portion 6b adheres to the upper surface of the water return plate portion 6b. Is guided to the mounting portion 6a, travels along the upper surface of the water return plate portion 6b, and is returned to the filler 3 through the gap 6e existing between the protruding portions 6c. Further, even when water droplets are ejected from the side surface of the filler 3 facing the eliminator 7 and fall on the upper surface of the water return plate portion 6b, the water returns to the filler 3 again through the upper surface of the water return plate portion 6b. To be planned. At this time, since the upper surface of the water return plate portion 6b is inclined so as to form a downward gradient toward the inside of the frame body 2, the water transmitted through the upper surface of the water return plate portion 6b is more efficiently transferred to the filler 3. Returned. Thus, the water returned to the filler 3 is again used for heat exchange with the outside air. On the other hand, the outside air from which water has been sufficiently removed from the eliminator 7 is passed to the exhaust passage 107 side.

  The water generated in the eliminator 7 disposed below the internal space S flows toward the inside of the frame 2 along the upper surface of the plate member 2h, and falls downward through the gaps between the support members 2g. . This water reaches another assembly unit 1 adjacent to the lower side of the assembly unit 1 in the assembly unit group 102, is returned to the filler 3 from the gap between the pressing members 2d of the frame 2, and exchanges heat with the outside air. To be served.

  As described above, in the assembly unit 1, a part of the circulating water that has been conventionally drained by the eliminator 7 and not returned to the filler 3 can be again used for heat exchange by the filler 3. Therefore, in the assembly unit 1, for example, when the cooling tower 100 is driven, a part of the circulating water in each filler 3 flows out of the filler 3 before sufficiently exchanging heat with the outside air. Therefore, it is possible to suppress the occurrence of a problem that the cooling efficiency of each filler 3 decreases due to the shortage of circulating water, and to increase the amount of circulating water provided for heat exchange with the outside air by the filler 3. Therefore, as a result, improvement in the cooling efficiency of the cooling tower 100 can be expected.

  In the first embodiment, the contact portion 6d of the support member 6 that is in surface contact with the side surface of each filler 3 is a flat surface. However, like the support member 6A of the modified example shown in FIG. A flat extension 6g may be provided on the inner surface of the filler toward the filler 3 side, and the extension 6g may be disposed so as to be sandwiched between two fillers 3 stacked one above the other. . In the assembly unit having such a configuration, in addition to the good cooling effect of the circulating water as in the first embodiment, the support member 6A is held by sandwiching the support member 6A between the fillers 3. Since it can position favorably, the effect which returns stably the water droplet which flows through the upper surface of the water return board part 6b to the filler 3 side can be anticipated. The extending portion 6g is not limited to a flat plate shape, and may be any shape such as a shaft member or a rib member.

  Hereinafter, a support member according to another embodiment of the present invention will be described focusing on differences from the support member 6 of the first embodiment.

<Embodiment 2>
As shown in FIG. 7, the support member 6B according to the second embodiment has the same structure as that of the support member 6. However, the support member 6B is different from the support member 6B in that a frame-like protrusion 6c1 is used instead of the rib-like protrusion 6c. ing. Specifically, the projecting portion 6c1 is formed by bending each end of a round bar member made of a round steel material at right angles in the same direction. In the support member 6B, the two protrusions 6c1 are connected and fixed to the upper surface and the lower surface of the water return plate 6b at both ends by welding or the like. A gap 6e is secured between the protrusion 6c1 fixed at each end and the water return plate 6b.

  When the support member 6B having such a configuration is used, as in the first embodiment, the lower end portion of the eliminator 7 positioned above is a protruding portion 6c1 provided upright on the upper surface of the water return plate portion 6b. And an upper end of the eliminator 7 positioned below and positioned between each side of the first column 2ca and the second column 2cb, and a protruding portion that is erected on the lower surface of the water return plate 6b 6c1 is positioned between each side of the first column 2ca and the second column 2cb, and is supported by the support members 6B in a state where the two eliminators 7 arranged in the vertical direction are erected. Further, when water droplets adhere to the upper surface of the water return plate portion 6b during driving of the cooling tower, the water droplets travel along the upper surface of the water return plate portion 6b, and are returned to the filler 3 through the gap 6e. Provided for heat exchange. Therefore, as in the first embodiment, it is possible to expect a good cooling effect of the circulating water in the filler 3.

  Furthermore, since the protrusion 6c1 can be formed by using a round bar member and bending both ends thereof, the support member 6B can be relatively easily manufactured.

<Embodiment 3>
As shown in FIGS. 8A and 8B, the support member 6C according to the third embodiment includes a flat portion 6b1 having an upper surface and a lower surface arranged substantially horizontally continuously to the mounting portion 6a, and a flat portion. An inclined portion 6b2 that is arranged continuously to 6b1 and is inclined so as to form a downward gradient with respect to the horizontal plane, and an extending portion 6g that extends substantially horizontally continuously to the inclined portion 6b2. Protruding portions 6c1 having the same configuration as the supporting member 6B of the second embodiment are provided on the upper and lower surfaces of the flat portion 6b1. Further, a protruding portion 6h that functions as a contact portion with respect to the side surface of the filler 3 and has the same configuration as the protruding portion 6c1 is provided on each of the upper surface and the lower surface of the extending portion 6g.

  As shown in FIG. 8B, the supporting member 6C has an extending portion 6g sandwiched between two fillers 3 stacked one above the other and a pair of projecting portions 6h. It arrange | positions so that the side surface of the filler 3 may be contact | abutted. As a result, like the support member 6A, the support member 6C is satisfactorily positioned by the two fillers 3. Further, when the two fillers 3 are likely to be displaced toward the support member 6C side, the two fillers 3 are supported by the support member 6C at the protruding portion 6h, and the displacement is prevented. On the other hand, the lower end portion of the upper eliminator 7 and the upper end portion of the lower eliminator 7 are sandwiched between the attachment portion 6a and each protrusion 6c1, and the support member 6C is placed in a state where each eliminator 7 is erected. Supported.

  Here, in the supporting member 6C, when water droplets adhere to the upper surface of the flat portion 6b1 when the cooling tower is driven, the water droplets are guided by the mounting portion 6a toward the inclined portion 6b2 and flow down the upper surface of the inclined portion 6b2. Due to the action of gravity at this time, the water droplets are urged to return to the filler 3 side along the upper surface of the extending portion 6g. Therefore, in the support member 6C, water droplets can be efficiently returned to the filler 3 side, and a good cooling effect of the circulating water can be expected.

<Other matters>
In the first embodiment, the configuration of the cross flow type cooling tower 100 is exemplified, but the cooling tower to which the present invention can be applied is not limited to this type, and may be applied to other types, for example, a counter flow type cooling tower. it can.

  Of course, the number of fillers 3 accommodated in the internal space S of the assembly unit 1 is not limited to four, and may be three or less or five or more. At this time, when three or more fillers 3 are stacked in the up-down direction, the plurality of support members 6 are arranged on the first pillar 2ca and the second pillar 2cb so that the side surfaces of the fillers 3 can be supported by the support members 6. You may build over the side.

  Although the assembly unit 1 has a configuration in which the louver 5 and the eliminator 7 are arranged on the frame 2, the louver 5 and the eliminator 7 are not essential configurations, and may be an assembly unit having a configuration in which at least one of them is omitted.

  In the internal space S, the assembly unit 1 is not limited to the configuration in which the support member 6 is provided between the side surface of the filler 3 and each side of the first pillar 2ca and the second pillar 2cb. For example, when a certain gap exists between the side surface of the filler 3 and each side portion of the third pillar 2cc and the fourth pillar 2cd, the side face of the filler 3 and the third pillar 2cc and the fourth pillar 2cd are also present. You may provide the support member 6 between each side part.

  You may form the 1 or several groove part extended toward the contact part 6d from the attaching part 6a in the upper surface of the water return board part 6b. Thus, it is considered that the water generated in the eliminator 7 can be circulated through the groove portion and efficiently returned to the filler 3. Further, the water return plate portion 6b may have a configuration having an insertion hole or a configuration having a frame structure. However, in order to obtain a good effect of returning the water generated in the eliminator 7 to the filler 3 side, it is desirable that the upper surface of the water return plate portion 6b has a certain area.

  The water return plate portion 6b may be arranged horizontally without inclining the upper surface. Even in such a configuration, the water dropping from the eliminator 7 can be guided by the mounting portion 6a by the mounting portion 6a, and can be returned to the filler 3 along the upper surface of the water return plate portion 6b. However, it is considered that if the upper surface of the water return plate portion 6b is inclined toward the inside of the frame body 2, the water transmitted through the upper surface of the water return plate portion 6b can be returned to the filler 3 more efficiently.

  The mounting portion 6a is not limited to the long plate-like configuration, and can be configured by using, for example, two plate materials arranged so as to overlap only at positions corresponding to the side portions of the first column 2ca and the second column 2cb. . However, if the attachment portion 6a is configured in a long plate shape as in the first embodiment and the attachment portion 6a also functions as a wall portion, the effect of efficiently guiding water falling from the eliminator 7 to the filler 3 side. Is desirable because it can be expected.

  In the first embodiment, the mounting portion 6a is formed in a long plate shape, so that the mounting portion 6a also serves as a wall portion standing outward from the position of the water return plate portion 6b on which the upper eliminator 7 is placed. However, the present invention is not limited to this, and a wall portion may be provided on the support member separately from the attachment portion 6a. In this case, for example, a wall portion having a certain height can be extended along the edge of the lower end portion of the eliminator 7 at a position near the attachment portion 6a on the upper surface of the water return plate portion 6b.

  The gas flowing into the filler 3 is not limited to the outside air, and may be a gas other than the outside air such as dry air or inert gas prepared separately.

  In the first embodiment, a plurality of assembly units 1 are stacked in a state where they are displaced toward the inside (exhaust passage 107 side) from the upper stage to the lower stage, so that the water flowing down from the upper assembly unit 1 flows into the lower stage. When the filler 3 arranged in the assembly unit 1 flows down, it is suppressed from being scattered to the exhaust passage 107 side with almost no heat exchange. However, the cooling tower to which the present invention is applied is not limited to the configuration in which the assembly unit 1 is arranged in this way. For example, the assembly units 1 positioned in the upper and lower stages may be arranged so as to be stacked straight in the vertical direction.

  In addition, when a plurality of assembly units 1 are installed in a plurality of stages in the vertical direction, a transfer member for transferring water falling on the top or bottom of the assembly unit 1 to the outside may be installed. Specifically, for example, as shown in FIG. 3, an inclined plate for allowing water falling from the upper direction between the plurality of installed support members 2 g to flow outward (to the left in FIG. 3). Can be provided. As a result, the water supplied at the lower part of the assembly unit 1 is transferred to the outside, so that the water flowing down in the assembly unit 1 arranged at the lower stage is dragged by the attracted air and is hardly exchanged in heat. It is possible to suppress movement to the inside of the material 3 (right direction in FIG. 3) and scattering to the eliminator 7 side. Such a transfer member is not limited to the lower part of the assembly unit 1, and may be installed on the upper part of the assembly unit 1. In this case, the water flowing down from the upper assembly unit 1 is transferred by a transfer member installed on the upper part of the lower assembly unit 1. Such a configuration is particularly effective when a plurality of assembly units 1 are vertically stacked.

  Moreover, you may make it provide the watering box (warm water box) provided with the watering hole (or watering nozzle) in the upper part of each assembly unit 1. FIG. Thus, by providing a hot water box in each assembly unit 1, water can be efficiently sprinkled on the filler 3 arranged in each assembly unit 1. In this case, since the watering nozzle 104a which spreads water is installed in the upper part of the cooling tower 100, when it laminates | stacks, you may use it for providing a watering box in the upper part of the assembly unit 1 of the 2nd stage | paragraph or more from the top. A watering box may be provided on the upper part of the assembly unit 1 located in the middle part of the cooling tower 100 (the assembly unit 1 in the third stage from the top in the case of FIG. 1). Such a configuration is particularly effective when the assembly units 1 are vertically stacked.

  The support member in the present invention is in principle in contact with the side surface of the filler, but in reality, a minute gap (for example, several millimeters) is formed between the support member and the side surface of the filler due to a construction error or the like. It is also conceivable that a certain degree of gap) occurs. However, even in such a configuration, when the filler can be displaced, the support member can contact the filler and support it. In the present invention, it is assumed that the support member is substantially in contact with the side surface of the filler even when such a minute gap is generated between the support member and the side surface of the filler.

  As described above, according to the cooling tower assembly unit of the present invention, it is possible to provide a cooling tower assembly unit capable of preventing the displacement of the filler in the frame body, which has an excellent effect. Therefore, it is beneficial to apply widely as an assembly unit for a cooling tower that can exhibit the significance of this effect.
