[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In order to solve the technical problem of high use cost of cooling device, the utility model provides a cooling water circulation system, which can reduce the use cost of cooling device.

[0029] It should be noted that the cooling water circulation system described in the utility model is used for but not limited to natural gas hydrogen production, etc. For the convenience of explanation, in the utility model, only a cooling water circulation system applied to natural gas hydrogen production is used as an example for explanation. The principle of applying a cooling water circulation system to other types of equipment is essentially the same as the principle applied to natural gas hydrogen production, and will not be repeated here.

[0030] See also Figure 1-6 A cooling water circulation system includes a rainwater collection unit 1 and a heat dissipation recovery unit 2. The rainwater collection unit 1 includes a collection tank 11, a sedimentation tank 12, a filter tank 13 and a clean water tank 14. The collection tank 11, the sedimentation tank 12, the filter tank 13 and the clean water tank 14 are connected in sequence. The heat dissipation recovery unit 2 includes a drain pipe 21 and a bracket 22. The bracket 22 is used to support the drain pipe 21 suspended directly above the filter tank 13. The drain pipe 21 is provided with a through hole 211 on the side wall facing the filter tank 13. The drain pipe 21 is used to recover cooling water to the filter tank 13.

[0031] In this embodiment, rainwater can be converted into cooling water by setting up the collection tank 11, the sedimentation tank 12, the filter tank 13 and the clear water tank 14, and then a through hole 211 is opened toward the filter tank 13 through the drainage pipe 21, so that the cooling water with heat can freely fall into the filter tank 13, and in the process of free fall of the cooling water, it can obtain effective natural heat dissipation, thereby realizing the reuse of cooling water. In summary, the utility model can use rainwater to supplement the reduced cooling water, saving the cost of supplementing the cooling water with tap water, thereby effectively reducing the use cost of the device.

[0032] First, rainwater is collected by the collection tank 11 and then discharged into the sedimentation tank 12; then, after the mud and other dirt in the rainwater sink to the bottom of the sedimentation tank 12, it is discharged into the filter tank 13; then, the filter tank 13 further filters the impurities in the rainwater and discharges it into the clean water tank 14, thus obtaining usable cooling water; finally, the drain pipe 21 recovers the cooling water after heat exchange, and after the heat is dissipated by free fall, it drips into the filter tank 13, so that the filter tank 13 can be discharged into the clean water tank 14 again, thus realizing the reuse of cooling water.

[0033] In one embodiment, see Figure 2 There are several drainage pipes 21, and the drainage pipes 21 are arranged at intervals from each other.

[0034] In this embodiment, the drainage pipes 21 are arranged at intervals from each other to facilitate other auxiliary cooling equipment (such as fans 23) to blow the cooling water with heat, thereby improving the heat dissipation efficiency of the recovered cooling water.

[0035] In one embodiment, see Figure 2 There are a plurality of through holes 211 , and the through holes 211 are evenly distributed along the length direction of the drain pipe 21 .

[0036] In this embodiment, the multiple through holes 211 allow the cooling water with heat to drip into the filter pool 13 respectively. Compared with the whole water flow, the provision of the multiple through holes 211 increases the heat dissipation area of ​​the cooling water with heat, and effectively improves the heat dissipation efficiency of the cooling water with heat.

[0037] In one embodiment, see Figure 2 — Figure 3 The heat recovery unit 2 further includes a fan 23 and a guide plate 24 . The fan 23 is fixedly connected to the side wall of the drain pipe 21 away from the through hole 211 , and the guide plate 24 is fixedly connected to the through hole 211 .

[0038] In this embodiment, the function of the fan 23 is to improve the heat dissipation efficiency of the cooling water carrying heat. The wind generated by the fan 23 blows downward from the gap between every two drainage pipes 21. Compared with the natural heat dissipation of the cooling water carrying heat, the fan 23 can improve the heat dissipation efficiency of the recovered cooling water. The function of the guide plate 24 is to guide the cooling water carrying heat into the filter tank 13 to prevent the cooling water carrying heat from falling outside the filter tank 13 and causing waste.

[0039] Furthermore, each through hole 211 is fixedly connected to the guide plate 24, and each guide plate 24 is spaced apart from each other to reduce occupied space, facilitate rapid flow of hot air, and facilitate heat dissipation of the cooling water carrying heat.

[0040] In one embodiment, see Figure 4 A filter basket 111 is detachably connected to the collection tank 11 .

[0041] In this embodiment, the function of the filter basket 111 is to filter large floating dirt such as leaves and branches to ensure the normal operation of the collection pool 11.

[0042] Furthermore, a plurality of protrusions are fixedly connected to the inner wall of the collection tank 11, and the filter basket 111 is slidably sleeved on the inner wall of the collection tank 11 and engaged with the protrusions, so that the staff can disassemble the filter basket 111 for cleaning.

[0043] In one embodiment, see Figure 5 The sedimentation tank 12 is provided with a cleaning port 121.

[0044] In this embodiment, the cleaning port 121 is used to facilitate the staff to clean the sediment in the sedimentation tank 12.

[0045] In one embodiment, see Figure 6 The clean water tank 14 is equipped with a water level detector 141.

[0046] In this embodiment, the water level detector 141 is used to monitor the water level in the clean water tank 14 in real time, so that the staff can adjust the water level in the clean water tank 14 according to the monitoring of the water level detector 141 .

[0047] In one embodiment, see Figure 6 A water level opening 142 is provided on the side wall of the clean water tank 14 .

[0048] In this embodiment, the water level opening 142 is connected to tap water. When the water level is too low in the dry season, the water level opening 142 is opened, and the tap water flows into the clear water tank 14 through the water level opening 142 to supplement the cooling water.

[0049] In one embodiment, see Figure 6 The side wall of the clear water tank 14 is provided with a plurality of water outlets 143 .

[0050] In this embodiment, the provision of multiple water outlets 143 enables the clean water tank 14 to be connected to multiple coolers, thereby satisfying the requirement that multiple coolers cool the mixed gas at the same time, thereby improving the cooling effect of the mixed gas.

[0051] Furthermore, each water outlet 143 is connected to a driving pump, and the driving pump is used to continuously pump cooling water in the clear water tank 14 to the cooler.

[0052] In one embodiment, see Figure 6 , and also includes a sewage pipe 3, the side walls of which are respectively connected to the collection tank 11, the sedimentation tank 12, the filtering tank 13 and the clean water tank 14.

[0053] In this embodiment, the function of the sewage pipe 3 is, on the one hand, to drain the collection tank 11, the sedimentation tank 12, the filter tank 13 or the clean water tank 14 to facilitate the staff to clean the inner wall of the tank, and on the other hand, to prevent the water level of the collection tank 11, the sedimentation tank 12, the filter tank 13 or the clean water tank 14 from being too high.

[0054] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0055] First, the rainwater enters the collection pool 11, and under the action of the filter basket 111, the rainwater is filtered once to remove larger impurities such as leaves; then, the rainwater in the collection pool 11 is discharged into the sedimentation tank 12 for sedimentation, so that the mud and sand sink to the bottom and are separated from the rainwater, that is, the rainwater is filtered twice; then, the rainwater in the sedimentation tank 12 is discharged into the filter tank 13, and the filter tank 13 filters the impurities in the rainwater three times and then discharges it into the clean water tank 14, that is, usable cooling water is obtained; finally, the fan 23 is started, and the cooling water after heat exchange flows out from each through hole 211 along the drain pipe 21 and flows into the filter tank 13 along the guide plate 24, wherein the wind force generated by the fan 23 continuously blows to the water on the guide plate 24 and the water in the filter tank 13, which effectively improves the heat dissipation efficiency of the water, and facilitates the filter tank 13 to be discharged into the clean water tank 14 for reuse.

[0056] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
