Description

Technical Field

[0001] The present application relates to the technical field of data centers, and more particularly, to a chemical dosing device and a data center. Background Art

[0002] Currently, the inlet and outlet pipes of industrial circulating water chemical dosing devices are connected to the supply and return water pipes of the circulating water pipes, and directly use the pressure difference between the supply and return water of the circulating water as the driving force for the liquid flow in the dosing device pipes to drive the chemical agent into the circulating water return pipe. Since the inlet and outlet pipes of the chemical dosing device are usually made of PVC material, after long-term use, especially the inlet and outlet pipes of the outdoor chemical dosing device are extremely prone to pipe rupture, resulting in a large amount of circulating water leakage. Moreover, the liquid mixed with the chemical agent is corrosive and can damage other equipment. Only when manual inspection discovers it will the manual isolation ball valve of the inlet and outlet pipes of the chemical dosing device be manually closed, with a slow reaction, wasting resources and making the system operation safety performance relatively low.

[0037] The chemical dosing device body 10 includes a chemical dosing device water pipe 11, and a chemical dosing hole 111 is provided on the chemical dosing device water pipe 11 for adding chemicals into the chemical dosing device water pipe 11.

[0038] The chemical dosing device supply pipe 20 is configured to connect the water inlet of the chemical dosing device water pipe 11 and the circulating water supply pipe 200, and the chemical dosing device return pipe 30 is configured to connect the water outlet of the chemical dosing device water pipe 11 and the circulating water return pipe 300.

[0039] The first chemical dosing bypass pipe 51 is arranged in parallel with the chemical dosing device supply pipe 20 through the first three-way valve 41 and the second three-way valve 42. For example, the first three-way valve 41 connects the circulating water supply pipe 200, the chemical dosing device supply pipe 20, and the first chemical dosing bypass pipe 51, and the second three-way valve 42 connects the chemical dosing device supply pipe 20, the first chemical dosing bypass pipe 51, and the chemical dosing device water pipe 11.

[0040] The second chemical dosing bypass pipe 52 is arranged in parallel with the chemical dosing device return pipe 30 through the third three-way valve 43 and the fourth three-way valve 44. For example, the third three-way valve 43 connects the chemical dosing device water pipe 11, the chemical dosing device return pipe 30, and the second chemical dosing bypass pipe 52, and the fourth three-way valve 44 connects the chemical dosing device return pipe 30, the second chemical dosing bypass pipe 52, and the circulating water return pipe 300.

[0041] The first leakage detection component 61 is used to detect the leakage condition of the chemical dosing device supply pipe 20, and the second leakage detection component 62 is used to detect the leakage condition of the chemical dosing device return pipe 30.

[0043] Wherein, the chemical dosing device body 10 further includes a chemical storage container for storing chemicals for treating circulating water, and the chemical storage container is connected to the chemical dosing hole 111 to facilitate feeding the chemicals into the chemical dosing device water pipe 11.

[0044] For example, the medicine storage container can be a medicine storage tank or a medicine storage barrel to facilitate the accommodation of the medicine. In some embodiments, the medicine in the medicine storage container is the medicine after being uniformly mixed. For example, it is a medicine solution formed by dissolving solid medicine and circulating water in proportion.

[0045] The main body 10 of the medicine adding device can be arranged indoors or outdoors according to the layout of the data center.

[0046] The water supply pipe 20 of the medicine adding device is a pipe for sending circulating water into the water pipe 11 of the medicine adding device. The water inlet end of the water supply pipe 20 of the medicine adding device is used to connect to the circulating water supply pipe 200, and the water outlet end of the water supply pipe 20 of the medicine adding device is used to connect to the water inlet of the water pipe 11 of the medicine adding device. It should be noted that the circulating water flowing out from the water outlet of the water pipe 11 of the medicine adding device is the circulating water mixed with the medicine. For the convenience of description, it is simply called circulating water.

[0047] The first medicine adding bypass pipe 51 is arranged between the circulating water supply pipe 200 and the water inlet of the water pipe 11 of the medicine adding device. The first medicine adding bypass pipe 51 is arranged in parallel with the water supply pipe 20 of the medicine adding device, so that there are two circulating water branches formed between the circulating water supply pipe 200 and the water inlet of the water pipe 11 of the medicine adding device. For example, one circulating water branch is: the circulating water in the circulating water supply pipe 200 can enter the water pipe 11 of the medicine adding device through the water supply pipe 20 of the medicine adding device; the other circulating water branch is: the circulating water in the circulating water supply pipe 200 can enter the water pipe 11 of the medicine adding device through the first medicine adding bypass pipe 51.

[0048] The first three-way valve 41 connects the circulating water supply pipe 200, the water supply pipe 20 of the medicine adding device and the first medicine adding bypass pipe 51, and the second three-way valve 42 connects the water supply pipe 20 of the medicine adding device, the first medicine adding bypass pipe 51 and the water pipe 11 of the medicine adding device to realize the parallel connection of the first medicine adding bypass pipe 51 and the water supply pipe 20 of the medicine adding device. The first three-way valve 41 is the inlet valve of the water supply pipe 20 of the medicine adding device and the first medicine adding bypass pipe 51, and the second three-way valve 42 is the outlet valve of the water supply pipe 20 of the medicine adding device and the first medicine adding bypass pipe 51.

[0049] The water return pipe 30 of the medicine adding device is a pipe for sending the circulating water mixed with the medicine into the circulating water return pipe 300. The water inlet end of the water return pipe 30 of the medicine adding device is used to connect to the water outlet of the water pipe 11 of the medicine adding device, and the water outlet end of the water return pipe 30 of the medicine adding device is used to connect to the circulating water return pipe 300.

[0050] The second chemical addition bypass pipe 52 is arranged between the water outlet of the water pipe 11 of the chemical addition device and the circulating water return pipe 300. The second chemical addition bypass pipe 52 is arranged in parallel with the chemical addition device return pipe 30, so that there are two circulating water (the circulating water here is mixed with chemicals) branches formed between the water outlet of the water pipe 11 of the chemical addition device and the circulating water return pipe 300. For example, one circulating water branch is: the circulating water mixed with chemicals flowing out of the water pipe 11 of the chemical addition device can enter the circulating water return pipe 300 via the chemical addition device return pipe 30; the other circulating water branch is: the circulating water mixed with chemicals flowing out of the water pipe 11 of the chemical addition device can enter the circulating water return pipe 300 via the second chemical addition bypass pipe 52.

[0051] The third three-way valve 43 is connected to the water pipe 11 of the chemical addition device, the chemical addition device return pipe 30 and the second chemical addition bypass pipe 52, and the fourth three-way valve 44 is connected to the chemical addition device return pipe 30, the second chemical addition bypass pipe 52 and the circulating water return pipe 300 to realize the parallel connection of the second chemical addition bypass pipe 52 and the chemical addition device return pipe 30. The third three-way valve 43 is the inlet valve of the chemical addition device return pipe 30 and the second chemical addition bypass pipe 52, and the fourth three-way valve 44 is the outlet valve of the chemical addition device return pipe 30 and the second chemical addition bypass pipe 52.

[0052] The first water leakage detection component 61 is used to detect the water leakage condition of the water supply pipe 20 of the chemical addition device. When it detects that the water supply pipe 20 of the chemical addition device has a water leakage, the first water leakage detection component 61 can give an alarm, for example, send a water leakage signal to the control system 70, and / or emit a water leakage warning light.

[0053] The second water leakage detection component 62 is used to detect the water leakage condition of the chemical addition device return pipe 30. When it detects that the chemical addition device return pipe 30 has a water leakage, the second water leakage detection component 62 can give an alarm, for example, send a water leakage signal to the control system 70, and / or emit a water leakage warning light.

[0054] The control system 70 can include a programmable logic controller (PLC). The control system 70 is connected to each electrical component through a cable or wirelessly (such as wifi).

[0055] The control system 70 is used to receive the water leakage information of the water supply pipe 20 of the chemical addition device sent by the first water leakage detection component 61. The control system 70 is used to adjust the working state of the first three-way valve 41. For example, switch the flow of the circulating water in the water supply pipe 20 of the chemical addition device or the first chemical addition bypass pipe 51, or cut off the circulating water from entering the water supply pipe 20 of the chemical addition device and the first chemical addition bypass pipe 51. The control system 70 is used to adjust the working state of the second three-way valve 42. For example, switch the circulating water to enter the water inlet of the water pipe 11 of the chemical addition device via the water supply pipe 20 of the chemical addition device or the first chemical addition bypass pipe 51, or cut off the circulating water from entering the water pipe 11 of the chemical addition device.

[0056] In some embodiments, under normal conditions, the circulating water provided by the circulating water supply pipe 200 enters the chemical dosing device water pipe 11 through the water inlet of the first three-way valve 41, the chemical dosing device water supply pipe 20, the second three-way valve 42, and the chemical dosing device water pipe 11. When the control system 70 receives the water leakage information of the chemical dosing device water supply pipe 20 sent by the first water leakage detection component 61, the control system 70 can adjust the working states of the first three-way valve 41 and the second three-way valve 42, and switch the circulating water to flow through the first chemical dosing bypass pipe 51, so that the circulating water provided by the circulating water supply pipe 200 enters the chemical dosing device water pipe 11 through the first three-way valve 41, the first chemical dosing bypass pipe 51, the second three-way valve 42, and the water inlet of the chemical dosing device water pipe 11, that is, block the circulating water from flowing through the chemical dosing device water supply pipe 20, so as to isolate the leakage part in time when the chemical dosing device water supply pipe 20 leaks, switch the circulating water conveying pipeline, and reduce the impact on the chemical dosing progress. In some special cases, for example, when the chemical dosing device water pipe 11 leaks, the control system 70 can preferentially adjust the working state of the first three-way valve 41 to cut off the circulating water from entering the chemical dosing device water supply pipe 20 and the first chemical dosing bypass pipe 51, and reduce the risk of circulating water entering the chemical dosing device water pipe 11.

[0057] The control system 70 is configured to receive the water leakage information of the chemical dosing device return pipe 30 sent by the second water leakage detection component 62. The control system 70 is configured to adjust the working state of the third three-way valve 43. For example, switch the circulating water to flow in the chemical dosing device return pipe 30 or the second chemical dosing bypass pipe 52, or cut off the circulating water from entering the chemical dosing device return pipe 30 and the second chemical dosing bypass pipe 52. The control system 70 is configured to adjust the working state of the fourth three-way valve 44. For example, switch the circulating water to enter the circulating water return pipe 300 through the chemical dosing device return pipe 30 or the second chemical dosing bypass pipe 52, or cut off the circulating water from entering the circulating water return pipe 300.

[0058] In some embodiments, under normal conditions, the circulating water provided by the water pipe 11 of the chemical dosing device enters the circulating water return pipe 300 via the third three-way valve 43, the chemical dosing device return pipe 30, and the fourth three-way valve 44. When the control system 70 receives the water leakage information of the chemical dosing device return pipe 30 sent by the second water leakage detection component 62, the control system 70 can adjust the working states of the third three-way valve 43 and the fourth three-way valve 44, and switch the circulating water to flow through the second chemical dosing bypass pipe 52, so that the circulating water provided by the water pipe 11 of the chemical dosing device enters the circulating water return pipe 300 via the third three-way valve 43, the second chemical dosing bypass pipe 52, and the fourth three-way valve 44, that is, block the circulating water from flowing through the chemical dosing device return pipe 30, so as to isolate the leakage part in time when the chemical dosing device return pipe 30 leaks, switch the circulating water conveying pipeline, and reduce the impact on the chemical dosing progress. In some special cases, for example, when the water pipe 11 of the chemical dosing device leaks, the control system 70 can preferentially adjust the working state of the fourth three-way valve 44 to cut off the circulating water from entering the circulating water return pipe 300.

[0086] According to some embodiments of the present application, the dosing device 100 further includes a first manual valve 81 and a second manual valve 82. The first manual valve 81 is used to connect between the circulating water supply pipe 200 and the first three-way valve 41, and the second manual valve 82 is used to connect the fourth three-way valve 44 and the circulating water return pipe 300.

[0087] The first three-way valve 41 has three interfaces, which are respectively connected to the circulating water supply pipe 200, the dosing device water supply pipe 20, and the first dosing bypass pipe 51. The circulating water supply pipe 200 is connected to the first three-way valve 41 through the first manual valve 81.

[0088] The fourth three-way valve 44 has three interfaces, which are respectively connected to the dosing device return pipe 30, the second dosing bypass pipe 52, and the circulating water return pipe 300. The circulating water return pipe 300 is connected to the fourth three-way valve 44 through the second manual valve 82.

[0089] In the above solution, the settings of the first manual valve 81 and the second manual valve 82 facilitate the maintenance and replacement of the dosing device water supply pipe 20, the first dosing bypass pipe 51, the dosing device water pipe 11, the dosing device return pipe 30, and the second dosing bypass pipe 52.

[0090] Please refer to Figure 1 and Figure 2, according to some embodiments of the present application, the chemical dosing device body 10 further includes a first valve 12, a flow meter 13, a pressurization bypass pipeline 14, and a booster pump 15. Along the flow direction of the fluid in the chemical dosing device water pipe 11, the first valve 12 is arranged on the upstream side of the chemical dosing device water pipe 11. The pressurization bypass pipeline 14 is arranged in parallel with the first valve 12. The booster pump 15 is arranged in the pressurization bypass pipeline 14. The flow meter 13 is arranged downstream of the first valve 12 and the pressurization bypass pipeline 14. The flow meter 13 and the booster pump 15 are respectively electrically connected to the control system 70. The flow meter 13 is used to detect the flow rate of the fluid in the chemical dosing device water pipe 11, and the booster pump 15 is used to increase the flow rate of the fluid in the chemical dosing device water pipe 11.

[0091] In some embodiments, the first valve 12 can be an electric valve. The first valve 12 is electrically connected to the control system 70. The control system 70 can adjust the working state of the first valve 12 according to the detection result of the flow meter 13. For example, when the detection result sent by the flow meter 13 to the control system 70 is less than the preset flow rate information, the control system 70 controls the first valve 12 to close, so that all the circulating water flows through the pressurization bypass pipeline 14, and at the same time controls the booster pump 15 to work, and improves the flow rate of the circulating water through the booster pump 15. In some other embodiments, the first valve 12 can also be a manual valve. When the control system 70 receives the detection result of the flow meter 13 less than the preset flow rate information, the staff manually closes the first valve 12.

[0092] The control system 70 presets the preset flow rate information of the flow rate of the fluid in the chemical dosing device water pipe 11. After the flow meter 13 sends the detection result to the control system 70, the control system 70 compares the detection result of the flow meter 13 with the preset flow rate information. When the detection result is less than the preset flow rate information, the control system 70 controls the first valve 12 to close, switches the circulating water to the pressurization bypass pipeline 14, and at the same time, controls the booster pump 15 to work, and improves the flow rate of the circulating water through the booster pump 15.

[0093] In the above solution, by arranging the flow meter 13 and the booster pump 15 in the chemical dosing device body 10, when the flow rate of the fluid flowing through the chemical dosing device water pipe 11 is detected to be low, the flow rate of the fluid in the chemical dosing device water pipe 11 can be increased, thereby reducing the risk of crystallization of the chemical agent in the chemical dosing device water supply pipe 20 and the chemical dosing device return pipe 30, reducing the risk of pipeline blockage, and being able to increase the flow rate of the chemical agent and improve the chemical dosing efficiency.

[0094] Please refer to Figure 1 and Figure 2, according to some embodiments of the present application, the pressurization bypass pipe 14 is provided with a second valve 16 and a third valve 17.

The second valve 16 is used to connect or disconnect the pressurization bypass pipe 14, and the third valve 17 is used to connect or disconnect the pressurization bypass pipe 14.

[0095] In some embodiments, the second valve 16 and the third valve 17 are manual valves. When it is necessary to repair or replace the pressurization pump 15, the second valve 16 and the third valve 17 can be manually closed.

[0096] In the above solution, the second valve 16 and the third valve 17 are arranged to facilitate the replacement and repair of the pressurization pump 15.

Along the flow direction of the fluid in the chemical dosing device water pipe 11, the pressurization bypass pipe is arranged upstream of the chemical dosing hole 111. The flowmeter 13 is preferably arranged at a position close to the chemical dosing device return pipe 30 of the chemical dosing device water pipe 11, so as to reduce the influence of other components (such as valves, pumps, etc.) on the measurement result of the flowmeter 13 and improve the measurement accuracy of the flowmeter 13.

[0098] The chemical dosing hole 111 is arranged in the middle and lower reaches of the chemical dosing device water pipe 11 to facilitate the pressurized circulating water to drive the chemical flow. In some embodiments, multiple chemical dosing holes 111 can be arranged on the chemical dosing device water pipe 11.

[0099] According to some embodiments of the present application, the present application embodiment also provides a data center, which includes a water circulation system and the chemical dosing device 100 provided in any of the above embodiments. The water circulation system includes a circulating water supply pipe 200 and a circulating water return pipe 300. The chemical dosing device supply pipe 20 connects the water inlet of the chemical dosing device water pipe 11 and the circulating water supply pipe 200, and the chemical dosing device return pipe 30 connects the water outlet of the chemical dosing device water pipe 11 and the circulating water return pipe 300.

[0100] According to the data center of the embodiments of the present application, the setting of the first water leakage detection rope 611, the second water leakage detection rope 621, the third water leakage detection rope 631, the first three-way valve 41, the second three-way valve 42, the third three-way valve 43, the fourth three-way valve 44, the first chemical addition bypass pipe 51, and the second bypass pipe realizes automatic water leakage identification and automatic valve closing to isolate the leakage. At the same time, by switching to the standby bypass pipe, not only is the leakage blocked, but also the impact on the chemical addition progress is reduced, the stability of the system operation is improved, the leakage is timely blocked, energy is saved, the impact on the operation safety of other equipment is reduced, and the safety of the system operation is improved. In addition, the setting of the flow meter 13 and the booster pump 15 can solve the problems of low chemical addition efficiency and blockage of the chemical addition pipeline.
