Problems solved by technology

Various types of cooling towers and cooling technologies are one direction of water saving, emission reduction, noise reduction and environmental protection. At present, the air inlet of the cooling tower is usually set at the tower body or the bottom of the tower, and the air outlet is usually set at the top of the tower above the water distribution device. In addition, a fan can be added at the air outlet to discharge the steam from the top of the tower. Therefore, this type of cooling tower is not suitable for occasions that require side air such as ventilation ducts and pits.

Embodiment 1

[0022] like figure 1 The centrifugal blast cross-flow closed cooling tower shown includes a tower body 1, a centrifugal blower fan 2, a water eliminator 3, and a water distribution device 4 and a heat exchange coil 5 fixed in the tower body 1 from top to bottom. , the water collector 3 and the centrifugal blower 2 are respectively arranged on both sides of the heat exchange coil 5, and the side inlet of the tower body 1 close to the centrifugal blower 2 is opened, and the air outlet of the centrifugal blower 2 is connected with the side inlet; the tower body 1 There is a side outlet near the outer wall of the water collector 3, which is located on the side wall of the tower body 1 corresponding to the water collector 3, and the water collector 3 is arranged in the tower body 1 and sealed to the side outlet; the water distribution device 4 There are a plurality of spray heads 41 for spraying hot water. The spray heads 41 are arranged above the heat exchange coil 5 and form a sp...

Embodiment 2

[0028] like image 3 As shown, the difference between the second embodiment and the first embodiment is that in the first embodiment, a side outlet is provided on the outer wall of the tower body 1 corresponding to the water eliminator 3, and the side outlet is arranged on the side wall of the tower body 1, while this In the embodiment, a top outlet is provided on the outer wall of the tower body 1 corresponding to the water eliminator 3 , and the top outlet is arranged at the top of the tower body 1 . In this way, the air entering the tower body 1 from the side inlet on one side of the heat exchange coil 5 will flow out from the top outlet on the other side of the heat exchange coil 5 after flowing through the heat exchange coil 5, so that not only can the hot water Cooling, and can make the centrifugal blast cross-flow open cooling tower can be applied to occasions like ventilation ducts, pits and the like that require side air.

Abstract

The invention discloses a centrifugal air blow transverse flow closed type cooling tower which comprises a tower body, a centrifugal air blower, a water collector, a water distribution device and a heat exchange coiler. The water distribution device and the heat exchange coiler are fixed into the tower body from top to bottom. The water collector and the centrifugal air blower are arranged on the two sides of the heat exchange coiler correspondingly. A side inlet is formed in one side, close to the centrifugal air blower, of the tower body. An air outlet of the centrifugal air blower is communicated with the side inlet. A side outlet or a top outlet is formed in the outer wall, close to the water collector, of the tower body. The water collector is arranged in the tower body and covers the side outlet or the top outlet in a sealing manner. The water distribution device is provided with multiple spraying heads for spraying hot water. The spraying heads are arranged above the heat exchange coiler, and a spraying area is formed between the spraying heads and a filling device. A cooling medium used for cooling hot water is arranged in the heat exchange coiler. The cooling tower can cool the hot water and recover the hot water and can be applied to occasions such as ventilation pipelines and pits where side air output is needed.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a centrifugal blast cross-flow closed cooling tower. Background technique [0002] With the development of my country's industry and urbanization, the contradiction between the rapid growth of water consumption and the relative scarcity of water resources, as well as the discharge of sewage and fog generated during the heat exchange process have caused great pressure on environmental protection. Various types of cooling towers and cooling technologies are one direction of water saving, emission reduction, noise reduction and environmental protection. At present, the air inlet of the cooling tower is usually set at the tower body or the bottom of the tower, and the air outlet is usually set at the top of the tower above the water distribution device. In addition, a fan can be added at the air outlet to discharge the steam from the top of the tower. Therefore, this type of cooling tower is not su...
