Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and in particular to a spray device for a closed cooling tower. Background Technology

[0002] A closed-circuit cooling tower is a highly efficient heat exchange device, widely used in industrial production, commercial buildings, and other fields. It achieves heat exchange by cooling the circulating medium. The medium is introduced into the closed-circuit cooling tower through cooling pipes. The cooling pipes evaporate the heat of the medium, and a spray device sprays water mist off the cooling pipes to accelerate the evaporation of heat, thereby achieving the cooling of the medium.

[0003] A patent application with publication number CN116399159A discloses a spraying device for a closed cooling tower. By spraying in multiple directions, it avoids the problem of uneven spraying caused by fixed nozzles, and improves the heat dissipation effect of cooling water contacting the bend pipe.

[0004] When the above-mentioned technical solution is used, if the nozzle becomes clogged, it is necessary to switch to a different nozzle to solve the clogging problem. During the switching process, the nozzle cannot continue to spray, and the operation of the cooling tower needs to be stopped, resulting in low operating efficiency of the cooling tower.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0018] like Figures 1-3 As shown, a spraying device for a closed cooling tower includes a cooling tower body 1. Cooling pipes are fixedly installed inside the cooling tower body 1. A first spray plate 2 is arranged above the cooling pipes inside the cooling tower body 1. A first sealing plate 3 is fixedly arranged at one end of the first spray plate 2. A second sealing plate 4 is fixedly arranged at the end of the first spray plate 2 away from the first sealing plate 3. A second spray plate 5 is fixedly arranged at one end of the second sealing plate 4. A third sealing plate 6 is fixedly arranged at the end of the second spray plate 5 away from the second sealing plate 4. A plurality of spray heads 7 are evenly arranged at intervals at the bottom ends of the second spray plate 5 and the first spray plate 2.

[0019] In a preferred embodiment, a filter plate 8 is provided inside the cooling tower body 1 at the lower end of the cooling pipe, and a water pump 9 is fixedly provided on one side of the lower end of the cooling tower body 1. The input end of the water pump 9 is connected to the interior of the cooling tower body 1, and the output end of the water pump 9 is connected to a liquid delivery pipe 10. Two liquid delivery hoses 11 are connected to the liquid delivery pipe 10. The sprayed liquid enters the bottom of the cooling tower body 1 after passing through the filter plate 8, and the filter plate 8 can filter the sprayed liquid.

[0020] In a preferred embodiment, a first sleeve 12 and a second sleeve 13 are fixedly installed on both sides of the upper end of the cooling tower body 1, and through holes 14 are opened on both side walls of the upper end of the cooling tower body 1. The through holes 14 are matched with the first sealing plate 3, the second sealing plate 4 and the third sealing plate 6, and sealing rubber pads are provided on the outer side walls of the first sealing plate 3, the second sealing plate 4 and the third sealing plate 6. When the sealing plate moves to the through hole 14, the sealing effect can be achieved under the action of the sealing rubber pad. Moreover, the setting of the sealing rubber pad can also improve the friction between the sealing plate and the through hole 14.

[0021] In a preferred embodiment, the first sealing plate 3, the third sealing plate 6, the first spray plate 2, and the second spray plate 5 are all provided with cavities 15. The cavity 15 inside the first sealing plate 3 is connected to the cavity 15 inside the first spray plate 2, and the cavity 15 inside the third sealing plate 6 is connected to the cavity 15 inside the second spray plate 5. Both infusion hoses 11 are provided with control valves. The spray liquid is pumped into the first sealing plate 3 or the third sealing plate 6 through the infusion hoses 11 and then enters the first spray plate 2 or the second spray plate 5.

[0022] In a preferred embodiment, the two infusion tubing 11 are respectively connected to the first sealing plate 3 and the third sealing plate 6, and pull rings 16 are fixedly provided on the outer side walls of the first sealing plate 3 and the third sealing plate 6, so that the sealing plates can be moved by pulling the pull rings 16.

[0023] In a preferred embodiment, the first sealing plate 3 is slidably disposed in the first sleeve 12, and the third sealing plate 6 is slidably disposed in the second sleeve 13. The arrangement of the first sleeve 12 and the second sleeve 13 can protect the unused sprinkler heads.

[0024] It should be noted that the working principle of this utility model is as follows: During use, the coolant is pumped into the cooling pipes for circulation cooling. During the circulation cooling process, the cooling fan at the top of the cooling tower 1 is turned on, and then the water pump 9 is turned on. The water pump 9 pumps the spray liquid at the bottom of the cooling tower 1 into the delivery pipe 10. The control valve on the corresponding delivery hose 11 is opened, so that the spray liquid enters the first sealing plate 3 and then enters the first spray plate 2. The spray head 7 at the bottom of the first spray plate 2 sprays the cooling pipes. The sprayed liquid flows back to the bottom of the cooling tower 1 through the filter plate 8 for recycling. When the spray head 7 needs to be replaced, pull the T-shaped insert 17 upward from the limiting groove 19 at the upper end of the third sealing plate 6. Then, by pulling the pull ring 16 on the outside of the first sealing plate 3, the pull ring 16 pulls the first sealing plate 3, the second sealing plate 4 and the third sealing plate 6 to move, thereby moving the first spray plate 2 to the outside of the cooling tower body 1, and moving the second sealing plate 4 to the through hole 14 on the left side of the cooling tower body 1. When the limiting groove 19 at the upper end of the first sealing plate 3 moves to the T-shaped insert 17 at the first sleeve 12, the T-shaped insert 17 is inserted into the limiting groove 19 at the first sealing plate 3. At this time, the second spray plate 5 enters the cooling tower body 1, and the third sealing plate 6 moves to the through hole 14 on the right side of the cooling tower body 1. Example

[0025] like Figure 4 As shown, the outer side walls of the first sleeve 12 and the second sleeve 13 are provided with T-shaped insert rods 17, and springs 18 are sleeved on the outer side of the T-shaped insert rods 17. Limiting grooves 19 are opened on the upper side walls of the first sealing plate 3 and the third sealing plate 6. Cover plates 20 are inserted into the bottom ends of the first sleeve 12 and the second sleeve 13.

[0026] When the used spray plate is moved to the outer end of the cooling tower body 1, the cover plate 20 at the bottom end of the sleeve of the spray plate is pulled outward, so that the bottom end of the sleeve is an open structure. Then the spray head 7 at the bottom end of the spray plate can be replaced without affecting the normal use of the cooling tower body 1.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. These are merely preferred embodiments of this utility model, described in detail, but should not be construed as limiting the scope of the utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of this utility model.
