Description

Technical Field

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

[0002] Mechanical ventilation cooling towers rely on the fan at the top of the tower to force air outside the tower into the tower, so that the rising airflow exchanges heat with the spraying water to cool the circulating water. In order to reduce the pump head and reduce noise pollution, high-position water collection cooling towers are gradually put into use. High-position water collection cooling towers are to suspend a water collection tank inside the tower body to collect the spraying water before it falls to the water collection tank at the bottom of the tower.

[0003] The Chinese patent document with the publication number CN215930609U discloses an energy-saving and noise-reducing mechanical ventilation cooling tower with a high-level water collection device, including a tower body, a civil engineering beam is arranged inside the tower body, a water spraying system is arranged at the bottom of the civil engineering beam, a water spraying filler is suspended below the water distribution spraying system through a first suspension device, and a water collecting tank is suspended below the water spraying filler through a second suspension device. The high-level water collecting tank is arranged outside the tower body, which is suitable for collecting the falling water in the water collecting tank. When working, the water flows through the circulating water pump to pump the water in the high-level water collecting tank into the water distribution spraying system, and then through the water spraying filler, heat is exchanged with the air circuit circulation, and the falling water is collected by the water collecting tank again and merged into the high-level water collecting tank to form a water circuit circulation. The above-mentioned cooling tower is more prominent in controlling the head and reducing noise, but the installation method of the water collecting tank is more complicated. At present, the installation method of the water collecting tank mostly adopts the method recorded in the above-mentioned patent document (see the attached document of the above-mentioned patent document). Figure 1 ), that is, the second suspension device includes a steel pipe that penetrates the water filling, a T-shaped hanger embedded in the water collection tank at the bottom, and a round tube connected to the civil engineering beam at one end and the other end that penetrates the steel pipe and is connected to the T-shaped hanger. Obviously, fixing the water collection tank by suspension is more troublesome to install and has poor connection stability. In addition, the distance between two adjacent water collection tanks is relatively large, which makes it difficult to ensure that the rising airflow is fully in contact with the water, resulting in the inability to ensure the heat exchange effect between the two.

[0021] The utility model provides a mechanical ventilation high-position water collection cooling tower, comprising a tower body 1, in which a dehumidifier 2, a water distribution device 3, a water sprinkling filler 4 and a high-position water collection device 5 are sequentially arranged from top to bottom, an air inlet 11 is provided on the side wall of the tower body 1 below the high-position water collection device 5, and a wind tube 12 is arranged on the top of the tower body 1, and a fan 13 is installed in the wind tube 12. During operation, the circulating water is sprayed onto the water sprinkling filler 4 under the action of the water distribution device 3, and the fan 13 is started, and the dry cold air outside the tower enters the tower through the air inlet 11, and the rising airflow exchanges heat with the sprinkling water after passing through the sprinkling filler 4, thereby cooling the circulating water, and after the rising airflow enters the dehumidifier 2, part of the water in the airflow is trapped in the dehumidifier 2, and finally flows out of the tower through the wind tube 12, and the sprinkling water passing through the sprinkling filler 4 falls into the high-position water collection device 5, thereby collecting the sprinkling water from a high position to reduce the pump head and noise. During specific implementation, a high-level water collection tank (not shown) is fixedly installed on the outer wall of the tower body 1, and the high-level hand water tank is connected to the high-level water collection device 5. The sprinkler water collected by the high-level water collection device 5 is finally collected and flows into the high-level water collection tank.

[0022] The high-position water collecting device 5 includes a mounting frame 51 and a plurality of water collecting structures 52 arranged in sequence below the mounting frame 51. A lap platform 101 is provided on the inner wall of the tower body 1. The mounting frame 51 is lapped on the lap platform 101 and fixedly connected to the lap platform 101. During installation, the high-position water collecting device 5 is hoisted into the tower body 1 from the upper end opening of the tower body 1 and lapped on the lap platform 101. Then, the mounting frame 51 is fixedly connected to the lap platform 101 to fix the high-position water collecting device 5.

[0023] In this embodiment, a lap plate 102 is provided on the inner wall of the tower body 1 below the water-spraying filler 4, the lap plate 102 is provided horizontally, and the lap platform 101 is formed by the upper surface of the lap plate 102. In other embodiments, the lap platform 101 may also be a step surface provided on the wall of the tower body 1, for example, the tower body 1 includes a thick-walled section located below and a thin-walled section located above the thick-walled section, a step surface is naturally formed between the thick-walled section and the thin-walled section, and the step surface constitutes the lap platform 101.

[0024] The mounting frame 51 includes a connecting plate 511 and a connecting column 512. The connecting plates 511 have two and are arranged opposite to each other. The connecting columns 512 have multiple and are fixedly connected between the two connecting plates 511 at intervals. The connecting columns 512 are perpendicular to the connecting plates 511. The connecting plate 511 is overlapped on the overlapping plate 102 and is fixedly connected to the overlapping plate 102, and the water collecting structure 52 is fixedly connected to the connecting column 512. In a specific embodiment, the connecting plate 511 is fixedly connected to the overlapping platform 101 by bolts.

[0025] There are multiple connecting columns 512, which can effectively improve the connection strength between the mounting frame 51 and the water collecting structure 52, and the multiple connecting columns 512 are arranged at intervals so that there is a gap between each two adjacent connecting columns 512, so that the circulating water passing through the water sprinkling filler 4 can enter the water collecting structure 52 through the gap.

[0026] The water collecting structure 52 includes a water collecting inclined plate 521 and a water collecting groove 522. The water collecting inclined plate 521 is fixedly connected to the connecting column 512, and the water collecting groove 522 is fixedly connected to the water collecting inclined plate 521. Between each two adjacent water collecting structures 52, the space sandwiched between the two water collecting grooves 522 constitutes an air flow channel 53. The end of the water collecting inclined plate 521 on one water collecting structure 52 is located above the end of the water collecting groove 522 on the other water collecting structure 52, and an air flow port 54 is formed between the two water collecting structures, and the air flow port 54 is connected to the air flow channel 53.

[0027] When the cooling tower is in operation, the circulating water that passes through the water spraying filler 4 falls onto the water collecting inclined plate 521, and flows along the water collecting inclined plate 521 into the water collecting tank 522. At the same time, the dry cold air that enters the tower body through the air inlet 11 flows upward, passes through the air flow channel 53 and the air flow port 54 in sequence, and then continues to flow upward. The air flow can directly and fully cool down the circulating water that flows down along the water collecting inclined plate 521, and at the same time, it can also cool down the spraying water that falls to the water collecting inclined plate 521, greatly improving the heat exchange efficiency. The circulating water that enters the water collecting tank 522 is finally collected in the high-level water collecting pool.

[0028] As a preferred embodiment, the water collecting inclined plate 521 includes an inclined flat plate 5211 fixedly connected to the connecting column 512 and an inclined arc plate 5212 connected to the lower end of the inclined flat plate 5211, the inclined flat plate 5211 and the connecting column 512 are welded, and the water collecting groove 522 includes a vertical plate 5221 fixedly connected to the inclined flat plate 5211 and an arc groove 5222 connected to the lower end of the vertical plate 5221, wherein an air flow channel 53 is formed between the arc groove 5222 and the adjacent vertical plate 5221, and an air flow port 54 is formed between the end of the arc groove 5222 and the end of the adjacent inclined arc plate 5212. The arc surface structure of the inclined arc plate 5212 and the arc groove 5222 can reduce wind resistance and facilitate air flow.

[0029] Furthermore, the upper end of the vertical plate 5221 is bent away from the arc groove 5222 to form a fixed end 5223, and the fixed end 5223 is fixedly connected to the inclined flat plate 5211. By setting the fixed end 5223, the contact area between the water collecting groove 522 and the water collecting inclined plate 521 is increased, thereby making the connection between the two more stable.

[0030] In a preferred embodiment, the upper surface of the inclined flat plate 5211 is provided with a mounting groove 5213, in which a sound-absorbing and splash-proof filler 5214 is fixedly installed, and the sound-absorbing and splash-proof filler 5214 is used to reduce the noise generated when the water falls onto the inclined flat plate 5211. In addition, the upper surface of the sound-absorbing and splash-proof filler 5214 is flush with the upper surface of the inclined flat plate 5211, so as to facilitate the circulating water to flow downward along the water collecting inclined plate 521.

[0031] In addition, in order to prevent the circulating water passing through the water spraying filler 4 from flowing to the bottom of the tower body 1 from the opposite sides of the water collecting structure 52, a first guard plate 55 is connected between one side of the mounting frame 51 and the end of the outermost water collecting inclined plate 521, and a second guard plate 56 is connected between the other side of the mounting frame 51 and the end of the outermost water collecting groove 522. The first guard plate 55 and the second guard plate 56 can prevent the spraying water from falling to the bottom of the tower body 1. Furthermore, a plurality of through holes 551 are provided on the water collecting inclined plate 521 connected to the first guard plate 55, so that the circulating water accumulated in the space formed by the first guard plate 55 and the water collecting inclined plate 521 can flow into the water collecting groove 522 after passing through the through holes 551, thereby discharging the accumulated water in time.

[0032] In the utility model, the structure and purpose of the water remover 2 are the same as those in the patent document with publication number CN215930609U, and the structure and purpose of the water distribution device 3 are the same as the water distribution spray system in the patent document with publication number CN215930609U, which will not be repeated here.

[0033] The mechanically ventilated high-position water-collecting cooling tower of the utility model overlaps and fixes the high-position water-collecting device 5 on the overlapping platform 101 on the inner wall of the tower body 1. Compared with the traditional installation method by setting a suspension device, the installation operation is simpler and easier to implement. At the same time, by improving the structure of the water-collecting structure 52, the airflow entering the tower can pass through the airflow channel 53 and the airflow port 54 in turn and then fully contact with the circulating water, thereby improving the heat exchange efficiency and having a significant cooling effect on the circulating water.
