Description

Technical Field

[0001] This utility model relates to the field of crossflow cooling tower technology, and in particular to a crossflow cooling tower multi-condition water distribution uniform device. Background Technology

[0002] Crossflow cooling towers are a common type of heat dissipation equipment widely used in industrial cooling. They typically have a rectangular structure and consist of an air inlet, fan, water distribution packing, and a water collection tank. The water distribution trough in a crossflow cooling tower is crucial for achieving uniform water distribution; a water distributor is installed below to ensure water is evenly sprayed onto the water distribution packing, ensuring efficient heat exchange.

[0003] In daily work, it has been found that the bottom of the water distribution trough in existing crossflow cooling towers is usually flat. However, when the actual operating water volume is less than the rated flow, the water distribution trough will have uneven water distribution, which will affect normal use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven water distribution in the water distribution trough when the actual operating water volume is less than the rated flow in the existing technology, and to propose a multi-condition water distribution uniform device for crossflow cooling towers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-condition uniform water distribution device for a crossflow cooling tower, comprising a crossflow cooling tower water distribution trough, a hot water inlet pipe installed on the surface of the crossflow cooling tower water distribution trough, a submerged section provided in the crossflow cooling tower water distribution trough, the submerged section being located directly below the hot water inlet pipe, multiple water distribution heads provided at the bottom of the crossflow cooling tower water distribution trough, a filter assembly provided at the upper end of the hot water inlet pipe, the filter assembly including a connecting pipe fixed to the upper end of the hot water inlet pipe, an interception net fixedly connected to the inner wall of the connecting pipe, and the connecting pipe... The surface is fixedly connected to two auxiliary pipes that communicate with the connecting pipe. One end of each auxiliary pipe is threaded with a sealing cap, and the surface of the sealing cap is provided with a cleaning section. A collection section is provided between the auxiliary pipe and the connecting pipe. Through the above components, a sinking section is designed. After the circulating water enters the water distribution tank, it overflows upward through the sinking section and then fills the entire water distribution tank. This design can reduce the uneven distribution of water when the actual operating water volume is less than the rated flow. When the hot water enters the liquid through the inlet pipe, the interception screen in the connecting pipe can intercept and filter it. At the same time, the cleaning section can perform cleaning operations, and the collection cylinder collects the liquid.

[0006] Preferably, the cleaning unit includes a cylinder fixed to the surface of the sealing cover, and a cleaning component is fixedly connected to the output end of the cylinder. When cleaning is performed, the cylinder is opened, and the cylinder can drive the cleaning component to move back and forth, thereby cleaning the impurities intercepted by the interception net into the collection unit for collection.

[0007] Preferably, the cleaning component includes a rod and a ring, with the ring fixed to the surface of the rod. During cleaning, the cleaning component mainly moves the impurities on the interception net by pushing them through the ring.

[0008] Preferably, the diameter of the ring is the same as the inner diameter of the auxiliary tube.

[0009] Preferably, the collecting part includes a feed inlet fixed on the surface of the auxiliary pipe, the feed inlet being connected to the auxiliary pipe, a collecting cylinder being threadedly connected to the surface of the feed inlet, a flexible tube being rotatably connected to the bottom of the collecting cylinder, and the other end of the flexible tube being fixedly connected to the connecting pipe and extending into the connecting pipe. Through the above components, the collecting cylinder can collect impurities, and then the liquid in the impurities can enter the connecting pipe through the flexible tube.

[0010] Preferably, the collecting cylinder includes a cylinder body and a filter screen, with the filter screen fixed in the inner wall of the cylinder body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, by designing a sinking section, the circulating water enters the crossflow cooling tower's water distribution trough and overflows upwards through the sinking section before filling the entire water distribution trough. This design can reduce uneven water distribution when the actual operating water volume is less than the rated flow rate.

[0013] In this invention, by setting up a filter assembly, the interceptor net inside the connecting pipe can effectively filter impurities in the hot water, reduce their entry into the crossflow cooling tower water distribution trough, reduce water distribution head blockage, ensure stable operation of the water distribution system, and the coordinated work of the cleaning section and the collection section realizes the automatic cleaning and collection of impurities in the interceptor net.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a crossflow cooling tower multi-condition water distribution uniform device, including a crossflow cooling tower water distribution trough 1, a hot water inlet pipe 2 installed on the surface of the crossflow cooling tower water distribution trough 1, a sinking section 5 set in the crossflow cooling tower water distribution trough 1, the sinking section 5 located directly below the hot water inlet pipe 2, multiple water distribution heads 3 set at the bottom of the crossflow cooling tower water distribution trough 1, a filter assembly 4 set at the upper end of the hot water inlet pipe 2, the filter assembly 4 including a connecting pipe 41 fixed to the upper end of the hot water inlet pipe 2, an intercepting net 45 fixedly connected to the inner wall of the connecting pipe 41, two auxiliary pipes 42 fixedly connected to the surface of the connecting pipe 41, a sealing cap 43 threadedly connected to one end of the auxiliary pipe 42, a cleaning part 44 set on the surface of the sealing cap 43, and a collection part 46 set between the auxiliary pipe 42 and the connecting pipe 41.

[0020] In this embodiment: a sinking section 5 is designed so that after the circulating water enters the water distribution tank, it overflows upward through the sinking section 5 and then fills the entire water distribution tank. This design can reduce the uneven distribution of water when the actual operating water volume is less than the rated flow. When the liquid enters through the hot water inlet pipe 2, the interception net 45 in the connecting pipe 41 can intercept and filter it. At the same time, the cleaning part 44 can perform cleaning operations, and the collection cylinder 461 collects the liquid.

[0021] Specifically, the cleaning unit 44 includes a cylinder 441 fixed on the surface of the sealing cover 43. The output end of the cylinder 441 is fixedly connected to a cleaning component 442. The cleaning component 442 includes a rod 4421 and a ring 4422. The ring 4422 is fixed on the surface of the rod 4421, and the diameter of the ring 4422 is the same as the inner diameter of the auxiliary tube 42.

[0022] In this embodiment: When cleaning, the cylinder 441 is opened, and the cylinder 441 can drive the cleaning component 442 to move back and forth. When cleaning, the cleaning component 442 mainly pushes the impurities on the interception net 45 to move through the ring body 4422, so that the impurities intercepted on the interception net 45 can be cleaned to the collection part 46 for collection.

[0023] Specifically, the collecting part 46 includes a feed inlet 463 fixed on the surface of the auxiliary pipe 42. The feed inlet 463 is connected to the auxiliary pipe 42. A collecting cylinder 461 is threadedly connected to the surface of the feed inlet 463. A flexible hose 462 is rotatably connected to the bottom of the collecting cylinder 461. The other end of the flexible hose 462 is fixedly connected to the connecting pipe 41 and extends into the connecting pipe 41. The collecting cylinder 461 includes a cylinder body and a filter screen. The filter screen is fixed in the inner wall of the cylinder body.

[0024] In this embodiment: the collection cylinder 461 can collect impurities, and then the liquid in the impurities can enter the connecting pipe 41 through the hose 462.

[0025] Working principle: During operation, hot water enters the crossflow cooling tower distribution trough 1 through the hot water inlet pipe 2. It first enters the connecting pipe 41, where the intercepting mesh 45 on the inner wall of the connecting pipe 41 filters impurities. The liquid then enters the crossflow cooling tower distribution trough 1. The sinking section 5 in the crossflow cooling tower distribution trough 1 allows circulating water to overflow upwards after entering the distribution trough, and then fill the entire crossflow cooling tower distribution trough 1. This reduces uneven distribution when the actual operating water volume is less than the rated flow. At the same time, when the intercepting mesh 45 intercepts a large amount of impurities, the cylinder 441 is opened. The cylinder 441 drives the cleaning component 442 to move back and forth. During cleaning, the cleaning component 442 mainly moves the impurities on the intercepting mesh 45 through the ring body 4422, thereby cleaning the impurities intercepted on the intercepting mesh 45 into the collection cylinder 461 for collection. After collection, the liquid produced can be discharged into the connecting pipe 41 through the hose 462.
