Embodiment 1

[0070] see figure 1 , the present embodiment is a single-axis driven single-guided double-layer spray counter-flow swirl cooling tower designed according to the first technical solution of the present invention. for liquid cooling. It includes a tower body 6, a set of transmission device 1, a water shield 11, two dispersing pinwheels 3, a defogging pinwheel 5, two layers of liquid spraying devices 4, a draft impeller 2, and a Cover tower body 6 support 8. The tower body 6 is urn-shaped, with a section of tapered diameter reduction at the top, and a sump and drainpipe at the bottom. The transmission device 1 includes a shaft, a bearing, a bearing box, and a motor. The motor and the shaft are directly connected through a coupling.

[0071] The needle wheel is that U-shaped needle seedlings 15 are uniformly and densely arranged in a radial shape and hung on the positioning ring 16. The positioning ring 16 of the needle seedlings 15 is hung and the spacer ring 17, backing plate...

Embodiment 2

[0077] see figure 2, this embodiment is a double-layer spray counter-flow swirl cooling tower with double-guided air-guiding and double-layer spraying under the lower drive designed according to the first technical solution of the present invention, which is used for liquid cooling. It includes a tower body 6, a set of transmission device 1, a water shield 11, two dispersing pinwheels 3, a defogging pinwheel 5, two layers of liquid spraying devices 4, a draft impeller 2, a wind turbine Barrel 13. The characteristics of the five parts including the water shield 11, the dispersing pin wheel 3, the defogging pin wheel 5, the liquid spray device 4, and the fan impeller 2 are exactly the same as those in the first embodiment, except that the transmission device 1 is fixed on the tower body 6 On the bracket 8, the bearing end 10 is fixed on the upper part of the tower body 6 with a flange through a channel steel truss. At the same time, a layer of cross-flow wind deflector is adde...

Embodiment 3

[0079] see image 3 , this embodiment is a single-shaft driven upper single-guided double-layer spray downstream swirl cooling tower designed according to the third technical solution of the present invention, which is used for liquid cooling. It includes a tower body 6, a transmission device 1, a water shield 11, a dispersing pin wheel 3, a defogging pin wheel 5, two-layer liquid spraying devices 4, and a draft impeller 2. The transmission device 1, the water shield 11, the dispersing pinwheel 3, the defogging pinwheel 5, the liquid spraying device 4, the exhaust impeller 2, and other five parts have the same characteristics as the first embodiment, except that the tower body 6 is self-contained.

Abstract

The swirling cooling tower of the invention belongs to the technical field of chemical cooling. The cooling tower of the present invention has no fillers, and it includes layered and stacked dispersion needle wheels 3 or demisting needle wheels 5, and a liquid spray device 4 in the middle. The needle wheels contain radially layered needle seedlings 15. The needle seedlings 15 are rotated to form a swirling flow with a uniform angular velocity. The cooling tower of the present invention increases the specific surface area and distribution uniformity of the liquid droplets through nozzle dispersion, swirl flow dispersion, and the collision and dispersion of the needle seedlings 15 to the droplets, and the swirl flow also increases the centripetal heat transfer speed of the airflow and enhances heat dissipation. effect and heat dissipation intensity, flatten and radialize the heat dissipation process; it is also possible to stack pinwheels and spray layers in layers, and the cross-flow cooling of the tower body 6 can also be divided into multiple layers at a certain height with the help of the air guide plate 7 to enter the air. It not only increases the temperature drop of the cooling tower but also greatly reduces the floor space of the cooling tower. The cooling tower of the present invention adopts the defogging needle wheel 5 to centrifugally remove the fog, which not only fully completes the water removal, but also allows the spray nozzle to have a wide atomization interval.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical industry cooling. 2. Background technology [0002] Today's cooling towers are divided into counter-flow type, cross-flow type, cross-counter-flow mixed type, and jet type. Some are natural ventilation and some are mechanical ventilation. Mechanical ventilation has suction and blower types. These technical types of cooling towers and their construction are so well established that they have remained virtually unchanged for nearly a century. The temperature drop of the common draft-type FRP cooling tower is generally about 5°C under standard working conditions. The temperature drop of a large hyperbolic duct-type natural draft cooling tower is generally around 7°C under standard working conditions. Drum-type natural draft cooling towers constitute a significant cost of investment in large industries such as thermal power plants. The development of cooling technology with high heat transfer ...
