Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a high-position water-collecting mechanical ventilation cooling tower with an annular water-collecting structure. Background Art

[0002] At present, the structure of conventional cooling towers in China generally places the water collection tank on the ground or underground. The circulating cooling water enters the tower from the water distribution pipe and is evenly sprayed onto the water sprinkling filler below according to the nozzles installed on the pipe. Heat exchange is carried out with the rising dry cold air in the filler. The cooled circulating water falls directly into the water collection tank below after passing through the filler.

[0003] To reduce the noise generated by pump head and circulating water falling to the bottom of the tank, high-level water collection cooling towers are becoming increasingly popular. These cooling towers feature a high-level water collection device installed within the cooling tower. This device is located below the packing and above the water collection tank. During operation, circulating water sprayed onto the packing flows through the packing and into the high-level water collection device. Because the high-level water collection device is significantly higher than a traditional water collection tank, the reduced height of the water drop reduces pump head and the noise generated by the circulating water falling.

[0004] However, in actual use, although most of the circulating water is collected by the high-position water collecting device, a small amount of circulating water will flow downward along the inner wall of the tower body after passing through the filler, resulting in this part of the circulating water being unable to enter the high-position water collecting device, and the water collection effect is poor. Based on this, it is necessary to improve the structure of the high-position water collection cooling tower to solve the problem that the circulating water cannot be fully collected due to wall flow. Utility Model Content

[0005] The technical problem to be solved by the present invention is: in the existing technology, the wall flow phenomenon in the cooling tower will cause the circulating water to be unable to fully flow into the high-position water collecting device. Based on this, the present invention provides a high-position water collection mechanical ventilation cooling tower that can ensure that the circulating water fully flows into the high-position water collecting device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a high-level water-collecting mechanical ventilation cooling tower with an annular water-collecting structure, comprising a tower body, a water-sprinkling filler and a high-level water-collecting device arranged inside the tower body, the high-level water-collecting device being located below the water-sprinkling filler, the high-level water-collecting device comprising a water-collecting inclined plate and a water-collecting trough connected to the bottom of the water-collecting inclined plate, an annular water-collecting structure being arranged inwardly along the circumference of the tower body on the inner wall of the tower body, the annular water-collecting structure being located between the water-sprinkling filler and the water-collecting inclined plate, the annular water-collecting structure and the inner wall of the tower body together forming a water-collecting trough, the upper end of the water-collecting trough being opened, the bottom of the water-collecting trough being connected to a water guide pipe, and the water guide pipe being connected to the water-collecting trough.

[0007] Furthermore, the annular water collecting structure includes a bottom plate and side plates connected to each other, the bottom plate is horizontally arranged on the inner wall of the tower body, the side plate is vertically connected to one side of the bottom plate, one end of the water pipe is connected to the bottom plate, and the water collecting trough is composed of the space enclosed by the bottom plate, the side plate and the tower body.

[0008] Furthermore, the annular water collecting structure and the tower body are integrally cast.

[0009] Furthermore, the annular water collecting structure and the tower body are fixedly connected by bolts.

[0010] Furthermore, the bottom wall of the water collecting trough is an inclined surface, and the water guide pipe is connected to the lower side of the inclined surface.

[0011] Furthermore, a plurality of concrete beams are provided inside the tower body above the water-spraying filler, and embedded hangers are fixedly connected to the concrete beams. Both ends of the embedded hangers are fixedly connected to a first hanging rope, and the lower end of the first hanging rope is fixedly connected to the water-spraying filler.

[0012] Furthermore, a steel pipe is fixedly installed on the bottom of the concrete beam, and the steel pipe is fixedly connected to the high-position water collecting device.

[0013] Furthermore, a water distribution pipe is provided in the tower body above the water sprinkling filler, and a nozzle is provided on the water distribution pipe.

[0014] Furthermore, a wind tube is installed on the top of the tower body, a fan is installed in the wind tube, and an air inlet is opened on the side wall of the bottom of the tower body.

[0015] The beneficial effects of the present invention are as follows: in the high-position water-collecting mechanical ventilation cooling tower with an annular water-collecting structure of the present invention, the circulating water flowing out from the edge of the water-spraying filler will flow downward along the inner wall of the tower body and eventually enter the water-collecting trough. Under the action of the water guide pipe, the circulating water flowing into the water-collecting trough will flow into the water collecting trough along the water guide pipe. In this way, this part of the circulating water can also be collected from a high place, ensuring that the circulating water is fully collected and preventing the circulating water from flowing along the inner wall of the tower body to the bottom of the tower body.

[0022] The utility model has a high-level water-collecting mechanical ventilation cooling tower with an annular water-collecting structure. When in use, the circulating water is sprayed on the water-spraying filler 2, and after heat exchange with the rising dry cold air, it passes downward through the water-spraying filler 2. Part of the circulating water falls directly on the water-collecting inclined plate 31, and then flows into the water collecting tank 32 along the water-collecting inclined plate 31. In this way, this part of the circulating water can be collected from a high place. During operation, the circulating water flowing out from the edge of the water-spraying filler 2 will flow downward along the inner wall of the tower body 1 and eventually enter the water collecting tank 401.

[0023] In this embodiment, the annular water collecting structure 4 includes a bottom plate 41 and a side plate 42 that are connected to each other. The bottom plate 41 is horizontally arranged on the inner wall of the tower body 1, and the side plate 42 is vertically connected to one side of the bottom plate 41, so that the longitudinal section of the annular water collecting structure 4 is an "L"-shaped structure. One end of the water pipe 5 is connected to the bottom plate 41, and the water collecting trough 401 is composed of the bottom plate 41, the side plate 42 and the space enclosed by the tower body 1.

In other embodiments not shown, a split structure can also be adopted between the annular water-collecting structure 4 and the tower body 1, and the annular water-collecting structure 4 and the tower body 1 are fixedly connected by bolts. In order to ensure the degree of sealing and prevent the leakage of circulating water, a seal can be provided between the connecting surface of the annular water-collecting structure 4 and the tower body 1.
