Description

Technical Field

[0001] The present application relates to the technical field related to circulating water cooling, and in particular to a containerized dry-wet closed tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through an evaporative heat dissipation device to ensure the normal operation of the system.

[0003] At present, during the use of cooling towers, as the use time increases, various problems will inevitably occur in the cooling tower, such as the fan at the top of the cooling tower. Cooling towers are usually large, and it is inconvenient to repair problems at the top of the cooling tower. For this reason, some cooling towers will be equipped with ladders on their outer walls to facilitate workers to carry out maintenance.

[0004] Since the ladder is fixedly installed on the outer wall of the cooling tower, non-maintenance personnel may climb to the top of the cooling tower through the ladder, resulting in accidents. Failure to install the ladder will affect the maintenance personnel's normal maintenance work, so there are shortcomings. Utility Model Content

A plurality of ladder rods 52 are welded inside the ladder box 51. The plurality of ladder rods 52 are arranged from top to bottom. The open end of the ladder box 51 faces the outside of the box body 1. A closing plate 53 is bolted to the open end of the ladder box 51. The closing plate 53 consists of an upper plate 531 and a lower plate 532. The closing plate 53 is used to hide the ladder rods 52 in the ladder box 51.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A guardrail 6 is bolted to the top of the box body 1, a guard ring 8 is welded to the guardrail 6, a ladder guardrail 7 is detachably arranged on the box body 1, and a hook rod 9 for hooking the guard ring 8 is welded to the ladder guardrail 7.

[0039] When the maintenance personnel need to repair the top of the box body 1, the maintenance personnel first remove the cover plate 53, and then hang the ladder guardrail 7 on the guardrail 6 through the interaction of the retaining ring 8 and the hook rod 9, and then bolt the ladder guardrail 7 to the box body 1 to fix it so that the guardrail 6 cannot move.

[0040] Afterwards, the maintenance personnel climb to the top of the box body 1 through the ladder rod 52 in the ladder box 51 to repair the fan 2 and other parts. When repairing the fan 2, the fan 2 can be removed for repair or replacement. When all repairs are completed, the maintenance personnel first remove and take away the ladder guardrail 7, and then bolt the covering plate 53 to the ladder box 51 again, so as to hide the ladder rod 52 in the ladder box 51.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The heat exchange component 3 includes a dry cooling tube 31 and a wet cooling tube 32 located below the dry cooling tube 31. A plurality of fins 10 are welded on the dry cooling tube 31. A plurality of hollow intermediate boxes 13 are welded on the box body 1. The intermediate boxes 13 are detachably arranged on the dry cooling tube 31 and the wet cooling tube 32. An external tube 33 is connected between the intermediate boxes 13 on the dry cooling tube 31 and the intermediate boxes 13 on the wet cooling tube 32. A liquid inlet pipe 34 is connected to the intermediate boxes 13 on the dry cooling tube 31 and the intermediate boxes 13 on the wet cooling tube 32. The opening end of the liquid inlet pipe 34 faces outside the box body 1.

[0042] Reference Figure 1 , Figure 2 and Figure 3 A spray component 35 for spraying water mist onto the wet cooling tube 32 is arranged on the box body 1. The spray component 35 includes a spray pipe 351 arranged between the dry cooling tube 31 and the wet cooling tube 32. A hollow cooling box 14 is welded inside the box body 1. The spray pipe 351 is detachably arranged on the cooling box 14. A plurality of nozzles 352 are welded on the spray pipe 351, and the nozzles 352 face the wet cooling tube 32.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A liquid collecting box 353 is arranged in the box body 1 and below the wet cooling pipe 32. A cooling pipe 15 is connected between the liquid collecting box 353 and the cooling box 14.

A water pump 354 is detachably connected to the cooling pipe 15, and the water pump 354 is electrically connected to the control system.

[0044] After the heat source liquid or gas is filled into the liquid inlet pipe 34, the worker starts the fan 2 and the water pump 354 through the control system. The water pump 354 transports the cooling water inside the liquid collection tank 353 to the cooling box 14 through the cooling pipe 15, and then sprays it out through the nozzle 352 on the spray pipe 351 connected to the cooling box 14. The sprayed coolant adheres to the wet cooling pipe 32 in the form of mist. At the same time, the fan 2 drives the air flow inside the box 1 to accelerate the heat exchange speed between the dry cooling pipe 31 and the wet cooling pipe 32.

[0045] The implementation principle of a container-type dry-wet closed tower in the embodiment of the present application is as follows: when the maintenance personnel need to repair the top of the box body 1, the maintenance personnel first remove the sealing plate 53, and then hang the ladder guardrail 7 on the guardrail 6 through the interaction of the guard ring 8 and the hook rod 9, and then bolt the ladder guardrail 7 to the box body 1 to fix it so that the guardrail 6 cannot move.

[0046] Afterwards, the maintenance personnel climb to the top of the box body 1 through the ladder rod 52 in the ladder box 51 to repair the fan 2 and other parts. When repairing the fan 2, the fan 2 can be removed for repair or replacement. When all repairs are completed, the maintenance personnel first remove and take away the ladder guardrail 7, and then bolt the covering plate 53 to the ladder box 51 again, so as to hide the ladder rod 52 in the ladder box 51.

[0047] After the heat source liquid or gas is filled into the liquid inlet pipe 34, the worker starts the fan 2 and the water pump 354 through the control system. The water pump 354 transports the cooling water inside the liquid collection tank 353 to the cooling box 14 through the cooling pipe 15, and then sprays it out through the nozzle 352 on the spray pipe 351 connected to the cooling box 14. The sprayed coolant adheres to the wet cooling pipe 32 in the form of mist. At the same time, the fan 2 drives the air flow inside the box 1 to accelerate the heat exchange speed between the dry cooling pipe 31 and the wet cooling pipe 32.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
