ある。(Prior art) Conventionally, in general, in this type of cooling tower, an upper water tank is placed above the filler loading chamber, and this upper water tank is used to supply heated circulating water sent from a refrigerator or the like. Some types are equipped with a riser pipe and a water supply header for distributing water to each upper water tank, and are also equipped with a stand for the upper water tank and a flow rate adjustment valve.
他方この冷却塔の上部構造を簡素化するため

ものである。 On the other hand, in order to simplify the upper structure of this cooling tower, the applicant had previously developed and filed a patent application filed in 1983.
-122355, Utility Model Application Publication No. 122355, Publication No. 30766, there is a device, but this device has beams made of square pipes installed along the tops of both sides of the filler loading chamber that also serve as water supply channels. A large number of water supply holes are provided on the side, and circulating water is sprayed directly into the filler loading chamber at the bottom.

ある。 In addition, the latter invention of the earlier application has a considerably improved superstructure of the cooling tower, and although it is somewhat effective, it still requires a water supply header and sprays the filler material directly into the loading chamber from a beam that also serves as a sprinkler pipe. Because of this, when the amount of water supplied is insufficient, it is not possible to spread the water evenly and it is difficult to adjust the distribution, so it feels like a step forward.
そこでこの考案の目的は冷却塔の上部を更に簡
素化すると共に、各上部水槽への給水量の調整が
容易にできる装置を市場に提供することにある。 Therefore, the purpose of this invention is to further simplify the upper part of the cooling tower and to provide the market with a device that can easily adjust the amount of water supplied to each upper water tank.

直交流式冷却塔とする。(Means for solving the problem) In order to achieve the above-mentioned problem, in this invention, a cooling tower beam is provided on at least one side wall of the upper water tank, and the inside of this beam also serves as a circulating water supply path. The beam that also serves as the circulating water supply channel has a square pipe-like cross section, and a water discharge slit is formed in the axial direction at the upper part of the side wall facing the upper water tank, and the lower edge of the water discharge slit is formed in the upper part of the side wall facing the upper water tank. is a water gutter double-purpose beam forming a weir, and the upstream end of each of the water discharge gutter double-purpose beams is connected and communicated with the side wall of the water supply header double-purpose beam in the horizontal direction in a direction perpendicular to these beams. It will be an AC cooling tower.

あることを特徴とする直交流式冷却塔とする。 In order to achieve the above-mentioned problem, this related invention is a cross-flow type cooling tower characterized in that a flow rate control valve is independently provided at the upstream end portion of each beam that also serves as a water gutter in a cross-flow type cooling tower. Make it a tower.

形成してあることを特徴とするする場合もある。 In addition, in order to achieve the above-mentioned problem, this invention is based on the fact that the upper edge of each weir of each gutter-cum-beam is formed to be lower from the upstream side to the downstream side in accordance with the flow gradient. Sometimes it is a feature.

上部水槽内に流入する。(Function) In this particular device configured as described above, when the circulating water supply pipe is connected to one end of the beam that also serves as the water supply header and circulating water is supplied, the circulating water flowing from the supply pipe is used as the water supply header as well. When the water level is higher than the weir of each gutter beam, it branches from the beam to each gutter beam and flows in the direction of the axis.
The circulating water all passes over this weir and flows into each upper water tank.

に調整する。 In the cross-flow type cooling tower according to claim 2, which is the related device, when the amount of water flowing into the upper water tank is different for each beam serving as a water gutter, the amount of water flowing into the upper water tank is in the vicinity of the upstream end of each beam serving as a water gutter. The flow rate control valves are each independently controlled to adjust the flow rates to be mutually equal and appropriate.

によつて流下水は冷却され、冷却塔の下部水槽に
集められて、送水ポンプによつて負荷部に送ら
れ、再び加熱されて、給水パイプに循環する。 The circulating water that has flowed into the upper water tank is sprayed from the upper water tank onto the group of fillers in the filler loading chamber in the same way as in known devices, and flows down using the surface of each filler in the group of fillers as a wet wall. The sewage water comes in contact with the outside air flowing in horizontally in the timber cluster, and is cooled by heat exchange through direct contact with the outside air and the latent heat of vaporization that accompanies partial evaporation of the sewage water, and flows into the lower water tank of the cooling tower. It is collected, sent to the load by a water pump, heated again and circulated to the water supply pipes.
放水樋兼用梁が上部水槽の相対する二辺に設け
てあるものにおいては、これら両側の放水樋兼用
梁より一斉に循環水は上部水槽に供給される。 In the case where beams serving as a water discharge gutter are provided on two opposing sides of the upper water tank, circulating water is simultaneously supplied to the upper water tank from the beams serving as a water discharge gutter on both sides.
また各放水樋兼用梁の各堰が流れ勾配に対応し

を載置でき保守管理時の作業性が向上する。(Effects) In this particular device which is constructed and operates as described above, the beam along at least one side of the upper water tank constituting the upper part of the cooling tower and the beam perpendicular to this are connected to the water supply channel, respectively. Since the beam is used as a beam that also serves as a water discharge gutter and a beam that also serves as a water supply header, the water supply pipe piping and water control valve do not protrude from the top of the cooling tower as in the case of conventional systems, which not only simplifies the installation work, but also makes the cooling tower The top surface is flat and the deck can be placed on it as it is, improving workability during maintenance management.
また冷却塔の上部が簡素化されるため資材の節
約ができ冷却塔自体の重量も軽減されコストもさ
げられる。 Furthermore, since the upper part of the cooling tower is simplified, materials can be saved, the weight of the cooling tower itself can be reduced, and costs can also be reduced.
さらに複雑な配管などが不要であるから、前記
放水樋兼用梁及び給水ヘツダー兼用梁の上面は排
気口に装備する送風機の減速機の架台として利用
できる。 Furthermore, since no complicated piping is required, the upper surfaces of the water gutter and water supply header beams can be used as a frame for the speed reducer of the blower installed at the exhaust port.
更に各放水樋兼用梁はそれぞれこの軸線方向に
長いスリツトを設けてその下側の側壁を堰とした

の全長にわたつて一斉に上部水槽に循環水は供給
され、各放水樋兼用梁の上流端部と下流端部にお
いて供給量の差は殆んど起こらない。 Furthermore, each gutter double-purpose beam has a long slit in the axial direction, and the lower side wall is used as a weir, so that regardless of the flow rate of the circulating water supplied, all the water is sent to the upper water tank all at once over the entire length of this weir. Circulating water is supplied, and there is almost no difference in the supply amount between the upstream end and the downstream end of each gutter-cum-beam.
殊に、前記関連考案においては、各放水樋兼用

部水槽に供給される水量を均一化しやすく、かつ
適量に調整しやすい。 In particular, in the related invention, since a flow rate control valve is provided at the upstream end of each gutter/beam, the amount of water discharged from each gutter/beam can be adjusted by adjusting the water level that passes over each weir. Adjustments can be made while visually observing changes, flow rate control is easy, and the amount of water supplied to each upper water tank is easy to equalize and adjust to an appropriate amount.
各放水樋兼用梁をそれぞれの上部水槽の両側に
設けたものにおいては、これらの断面が大きなも
のを必要とせず、間梁を設ける部分が少なくなる
し、それぞれの上部水槽内での給水斑が少なくな
る。 In the case where beams that also serve as water discharge gutter are installed on both sides of each upper water tank, there is no need for these beams to have a large cross section, the number of areas to be provided with beams is reduced, and water supply spots in each upper water tank are reduced. It becomes less.
各放水樋兼用梁の堰が供給水の流れ勾配に対応
した傾斜角が設けてあるものにおいては、殊の外
前記堰全長において均一な放水がきる。 If the weir of each beam serving as a water discharge gutter is provided with an inclination angle corresponding to the flow gradient of the supplied water, water can be discharged uniformly over the entire length of the weir.
