【考案の詳細な説明】
この考案は冷却塔の空気取入れ口に可動ルーバ
を設け、該可動ルーバは流入風圧によつて自動的
に開閉させて冷却水の塔外飛散を防止した冷却塔
に関するものである。[Detailed description of the invention] This invention relates to a cooling tower in which a movable louver is provided at the air intake of the cooling tower, and the movable louver is automatically opened and closed by inflow wind pressure to prevent cooling water from scattering outside the tower. It is.
従来の冷却塔においては、第３図に示すように
冷却塔内に外気を取入れるため、該塔下部に空気
取入れ口５を設けると共にこの部分に固定ルーバ
６′を所定の間隙をおいて設けている。この固定
ルーバ６′によつて塔内に散水された冷却水１０
が塔外に飛散するのを防止している。 In a conventional cooling tower, in order to take outside air into the cooling tower, an air intake 5 is provided at the bottom of the tower, and a fixed louver 6' is provided at a predetermined gap in this part, as shown in FIG. ing. Cooling water 10 sprinkled into the tower by this fixed louver 6'
prevents it from scattering outside the tower.
しかし、強い横風が吹いた場合に、一方の空気
取入れ口より取入れられた横風は他方の空気取入

な冷却水の飛散防止効果を達成しえなかつた。 However, when a strong crosswind blows, the crosswind taken in from one air intake may blow through to the other air intake, and in this case, the cooling water 1
Despite the provision of the louver 6', a portion of the cooling water was carried away from the tower by the crosswind, so a sufficient effect of preventing the cooling water from scattering could not be achieved.
この考案は、前記欠点を除去したものであつ
て、従来の固定ルーバーに代えて、風圧によつて
起倒自在な可動ルーバを冷却塔の空気取入れ口に
配設することにより、塔内に散水された冷却水の
塔外飛散を防止した冷却塔である。 This invention eliminates the above-mentioned drawbacks, and instead of the conventional fixed louver, a movable louver that can be raised and lowered by wind pressure is installed at the air intake of the cooling tower, thereby spraying water inside the tower. This is a cooling tower that prevents the cooling water from scattering outside the tower.
以下付図に示す実施例により本考案を説明す

槽であり、支持脚９によつて支持されている。 FIG. 1 shows a longitudinal cross-sectional view of the cooling tower of the present invention, in which an air intake port 5 is provided at the lower side of the tower body 1, and a movable louver 6 (described later) is provided at the air intake port 5.
are placed. In addition, 2 is a fan, which discharges the cooled air, which has been sucked in through the air intake port 5 and has cooled the cooling water 10 that has been sprayed through the sprinkler pipe 3 while passing through the packing 4, out of the tower. Further, 8 is a lower water tank, which is supported by support legs 9.
さて、冷却塔の空気取入れ口５に配置された可
動ルーバ６の一実施例を第１図によつて説明す
る。 Now, one embodiment of the movable louver 6 disposed at the air intake port 5 of the cooling tower will be described with reference to FIG.
可動ルーバ６は固定ルーバ片６３と可動ルーバ
片６１及び水平回転軸６２からなり、固定ルーバ

よつて冷却塔の運転休止時は起立して空気取入れ
口５を閉止している。 The movable louver 6 consists of a fixed louver piece 63, a movable louver piece 61, and a horizontal rotating shaft 62, and the fixed louver pieces 63 have the same shape as conventional louvers and are arranged in the air intake port 5 at predetermined intervals in the vertical direction. A movable louver piece 61 is provided at the upper end of the fixed louver piece 63, surrounding the air intake, and supported by a horizontal rotating shaft 62 so as to fall or stand up inside the tower. Furthermore, the movable louver piece 61 is divided into predetermined widths and surrounds the air intake port 5. Although not shown, the movable louver piece 61 is supported by a coil spring attached to the horizontal rotating shaft 62. When the cooling tower is out of operation, the person stands up and closes the air intake port 5.
第２図は可動ルーバの他の実施例であつて、第
１図と同様に空気取入れ口５に可動ルーバ７を配

る。 FIG. 2 shows another embodiment of the movable louver, in which a movable louver 7 is arranged in the air intake port 5 in the same way as in FIG. The movable louver pieces 71 are arranged in the vertical direction of the air intake 5 in a shutter-like manner to surround the air intake 5, and the upper end of the movable louver pieces 71 is supported by a horizontal rotating shaft 72, so that when the cooling tower is not in operation, He stands up and closes the air intake port 5.
さて、本考案の冷却塔の運転時について説明す
れば、塔内設置のフアン２を回転されることによ
つて塔体内が負圧になるので、第１図においては
可動ルーバ片６１がコイルスプリングの力に抗し

は塔内が負圧になると可動ルーバ片７１は水平回
転軸７２を支点として矢印方向に回転して空気取
入れ口５を開放して、この部分より外気を吸入す
る。 Now, to explain the operation of the cooling tower of the present invention, when the fan 2 installed inside the tower is rotated, negative pressure is created inside the tower. It falls into the tower against the force of , opens the air intake port 5, and takes outside air into the tower. In the case of FIG. 2, when the inside of the tower becomes negative pressure, the movable louver piece 71 rotates in the direction of the arrow about the horizontal rotating shaft 72, opens the air intake port 5, and draws outside air from this part.
また塔内に外気を取入れ中に第１図の矢印にて
示す如く強い横風が吹いた場合には、横風の上流
側の可動ルーバ６はより大きく空気取入れ口５を
開くが、下流側のルーバ６はこの横風の風圧によ
つて起立して空気取入れ口５を閉止する。したが
つて横風によつて冷却水１０が塔外に飛散するこ
とがない。第２図においても第１図と同様に横風
の上流側のルーバ７はより大きく空気取入れ口５
を開き、下流側の空気取入れ口５は自動的に閉止
して冷却水１０の塔外飛散を防止する。 In addition, if a strong crosswind blows as shown by the arrow in Figure 1 while outside air is being taken into the tower, the movable louver 6 on the upstream side of the crosswind will open the air intake 5 to a larger extent, but the louver on the downstream side will 6 stands up due to the wind pressure of this cross wind and closes the air intake port 5. Therefore, the cooling water 10 is not scattered outside the tower by cross winds. In Fig. 2, as in Fig. 1, the louver 7 on the upstream side of the crosswind is larger and the air intake 5 is larger.
is opened, and the air intake port 5 on the downstream side is automatically closed to prevent the cooling water 10 from scattering outside the tower.
尚、可動ルーバー片６１，７１はわずかな風圧
で作動するように種々調整しておくのが好まし
い。 Note that it is preferable that the movable louver pieces 61, 71 be adjusted in various ways so that they operate with slight wind pressure.
本考案は以上述べた如き構成の冷却塔であるの
で、以下に述べる如き利点がある。 Since the present invention is a cooling tower configured as described above, it has the following advantages.
すなわち、本考案の冷却塔は運転中強い横風が
吹いても冷却水が塔外に飛散することがないの
で、冷却水の有効な利用が可能となるとともに、
冷却水の飛散による汚染及び環境の悪化を防止で
きる等種々の利点を有するものである。 In other words, in the cooling tower of the present invention, even if a strong cross wind blows during operation, the cooling water does not scatter outside the tower, so the cooling water can be used effectively, and
This has various advantages such as being able to prevent pollution and environmental deterioration due to splashing of cooling water.
