Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers, and particularly relates to a cooling tower with in-tower water inlet distribution and sectional water distribution. Background Technique

[0002] The following problems exist in the connection pipes and operation of existing cooling towers:

[0003] 1. When most cooling towers are connected with pipes, whether it is the internal connection pipe or the external connection pipe, they mostly enter the water distribution basin from the top of the tower. This method is not convenient for arranging multiple water inlets on each side of the water distribution basin. Generally, only a single water inlet is arranged. Therefore, the water pressure at the water inlet is relatively high, the flow velocity is relatively large, the water flow impact sound is relatively large, and vortices are likely to appear, which is not conducive to uniform water distribution. In addition, this connection pipe method increases the height of the tower body, which is obviously not applicable when the site height is limited.

[0004] 2. When the cooling tower still needs to operate in winter at low temperatures, due to the small heat load, the cooling water volume is very small, so that some nozzles far from the water inlet cannot distribute water, which is particularly likely to cause icing at the air inlet surface of the packing and the air outlet at the top of the cooling tower. Content of the Utility Model

[0005] In view of the above problems, the utility model provides a cooling tower with in-tower water inlet distribution and sectional water distribution, which can effectively reduce the noise of water flow impact, make the water distribution uniform, thereby improving the cooling efficiency of the cooling tower, and is particularly suitable for working conditions with limited site height and low-temperature operation in winter, and can prevent the cooling tower from icing.

[0006] To achieve the above object, the technical solution adopted by the utility model is:

[0007] A cooling tower with in-tower water inlet distribution and sectional water distribution includes an internal connection pipe, and the internal connection pipe extends upward from the tower and branches into a water distribution pipe; water inlet conduits are arranged on the side wall of the water distribution pipe; the water inlet conduits pass through the side wall of the corresponding water distribution basin and enter the water distribution basin; the water distribution basin is divided into a first water distribution area and a second water distribution area by sectional water distribution strips; an energy-consuming cover is arranged in the first water distribution area; the outlet of the water inlet conduit extends into the energy-consuming cover.

[0008] As a further improvement of the above solution, the height of the sectional water distribution strip is lower than the height of the water distribution basin.

[0009] As a further improvement of the above solution, a plurality of water inlet conduits are uniformly arranged on the side wall of the water distribution pipe and enter the water distribution basin.

[0010] As a further improvement of the above solution, in the first water distribution area, a flow guide plate for guiding water to the side is arranged opposite to the outlet of the water inlet conduit; the flow guide plate is of a V-shaped structure.

[0011] As a further improvement of the above solution, the energy-consuming cover is a closed cover structure that covers a part of the first water distribution area; the side of the energy-consuming cover is provided with openings for connecting the water inlet conduit.

[0012] As a further improvement of the above solution, the first water distribution area is located on the outer side of the cooling tower; the water inlet conduit enters the first water distribution area after passing through the second water distribution area.

[0013] As a further improvement of the above solution, the area of the first water distribution area is smaller than that of the second water distribution area.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The present utility model solves the problem that the water inlet connection pipe is limited by the site height by arranging the built-in water inlet pipe to enter water from the inner side of the water distribution basin.

[0016] 2. The present utility model solves the problem of icing at the air inlet surface of the packing and the air outlet of the tower top during the winter operation of the cooling tower by means of zoned water distribution.

[0017] 3. By reasonably configuring the water flow velocity of the water inlet branch pipes and the combined use of the energy-consuming cover and the zoned water distribution strips, the present utility model effectively reduces the vortices and noises generated by the water flow impact vibration, makes the water distribution of the nozzles more uniform, and thus improves the cooling performance of the cooling tower.

[0023] In order to enable those skilled in the art to better understand the technical solution, the present utility model will be described in detail below in conjunction with embodiments. The description of this part is only exemplary and explanatory, and shall not have any restrictive effect on the protection scope of the present utility model.

[0024] Such as Figures 1-4As shown in the figure, the specific solution of this embodiment is as follows: A cooling tower with in-tower water inlet and partitioned water distribution includes an inner connecting pipe 9, which is installed inside the cooling tower and is connected to the water collecting basin of the cooling tower at the lower end; there are two water distribution basins 3 arranged at the top of the cooling tower; water spraying nozzles are arranged on the bottom surface of the water distribution basin 3; the inner connecting pipe 9 extends upward from inside the tower and branches into two branch water pipes 6; an inlet water conduit 5 is arranged on the side wall of each branch water pipe 6; the inlet water conduit 5 passes through the side wall 10 of the corresponding water distribution basin and enters the water distribution basin 3; the water distribution basin 3 is divided into a water distribution area 7 and a water distribution area 8 by a partitioned water distribution strip 2; the purpose of the partitioned water distribution strip 2 is to divide the water distribution basin 3 into two areas; when the water inlet is small, it is convenient to make the water evenly distributed in the water distribution area 7; an energy-consuming cover 1 is arranged in the water distribution area 7; the outlet of the inlet water conduit 5 extends into the energy-consuming cover 1. The height of the partitioned water distribution strip 2 is lower than the height of the water distribution basin 3. A plurality of inlet water conduits 5 are evenly arranged on the side wall of the branch water pipe 6 and enter the water distribution basin 3. In the water distribution area 7, a flow guiding plate 4 for guiding the water to the side is arranged opposite to the outlet of the inlet water conduit 5; the flow guiding plate 4 is of a V-shaped structure, and the flow guiding plate 4 is installed on the side wall 10 of the water distribution basin and is directly opposite to the water outlet of the inlet water conduit 5. The energy-consuming cover 1 is a closed cover structure that covers a part of the water distribution area 7; the side of the energy-consuming cover 1 is provided with an opening for connecting the inlet water conduit 5. The water distribution area 7 is located on the outer side of the cooling tower; the inlet water conduit 5 passes through the water distribution area 8 and then enters the water distribution area 7. The area of the water distribution area 7 is smaller than the area of the water distribution area 8.

[0025] Specifically: The water inlet design of the inner connecting pipe 9 of this device enters the water distribution basin 3 from inside the tower, thus solving the tower height problem caused by the inner connecting pipe 9 entering the water distribution basin 3 from the top of the tower. The number of branch pipes can be set according to the actual flow rate before entering the water distribution basin 3, so as to control the flow rate of the cooling water entering the water distribution basin 3 and reduce the impact of the water flow.

[0026] A flow guiding plate 4, an energy-consuming cover 1, and a partitioned water distribution strip 2 are arranged in the water distribution basin 3. The flow guiding plate 4 plays a role in guiding the flow and making the flow uniform, reducing noise and vibration; the energy-consuming cover 1 plays a role in sealing and reducing noise, stabilizing the flow and stopping the vortex; the partitioned water distribution strip 2 plays a role in supporting the inlet water conduit 5, stabilizing the flow and stopping the vortex, and partitioning the water distribution.

[0027] The cooling water enters the water distribution basin 3 after being guided by the flow guiding plate 4 through the inlet water conduit 5. When the cooling water volume is large in summer, the water level in the water distribution basin 3 is high, and the cooling water flows through the energy-consuming cover 1 for energy consumption and flow stabilization and then overflows the partitioned water distribution strip 2. At this time, the partitioned water distribution strip 2 also plays a role in stabilizing the flow and stopping the vortex. At this time, the cooling water in the entire water distribution basin 3 is stable and evenly distributed after being stabilized and vortex-stopped by the energy-consuming cover 1 and the partitioned water distribution strip 2. When operating at a low flow rate in winter, the water level is very low. The partitioned water distribution strip 2 divides the water distribution basin 3 into an area 1 and an area 2. The cooling water flows through the energy-consuming cover 1 for energy consumption and flow stabilization and then preferentially fills the nozzles in area 1. This can ensure that the nozzles on the air inlet surface of the packing of the entire tower body can all distribute water, forming a hot water curtain on the air inlet surface of the packing, effectively preventing cold air from entering the tower and causing ice formation at the air outlet of the tower top, and also effectively removing the ice hanging on the air inlet surface of the packing.
