[0002] With the rapid development of information technology, the scale and number of data centers are constantly increasing. The operation of data centers relies on efficient cooling systems to maintain the normal operating temperature of the equipment. However, the secondary system circulating water is prone to scaling during the cooling process. Scaling can lead to reduced cooling efficiency, increased energy consumption, and increased risk of equipment failure. Therefore, the data center industry has an urgent need for efficient and environmentally friendly circulating water descaling processes. Existing descaling technologies use continuous injection of descaling agents, which leads to excessively high concentrations of descaling agents in the proximal pipeline, which corrodes the equipment, and insufficient concentrations at the distal end, which affects the descaling effect. Some also use filtration, but this requires downtime, disassembly, and cleaning, resulting in long system maintenance cycles and seriously affecting the continuous operation of the data center.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] See also Figures 1 to 6 An embodiment of the present invention provides a descaling device for a liquid cooling circulating water system, which includes a descaling pipe 1, an injection component 2, and a driving component 3.

[0028] In the embodiments of the present invention, please refer to Figures 1 to 6 A liquid inlet branch 11 and a liquid discharge branch 12 are fixedly installed on the descaling pipe 1, and an additive branch 13 is fixedly installed on the middle pipe body of the descaling pipe 1, and a connecting flange 131 is fixedly installed on the additive branch 13. Valve A15 is installed on both the liquid inlet branch 11 and the liquid discharge branch 12. The liquid inlet branch 11 and the liquid discharge branch 12 are respectively connected to the liquid cooling circulating water main pipeline 6 through flanges, and a valve B7 is fixedly installed on the liquid cooling circulating water main pipeline 6 between the liquid inlet branch 11 and the liquid discharge branch 12.

[0029] It should be noted that the liquid cooling circulating water main pipe 6 in the present application is any pipe body in the liquid cooling circulating water pipe system, and two branch pipes are provided on the pipe body to communicate with the liquid inlet branch pipe 11 and the liquid discharge branch pipe 12, and the additive branch pipe 13 is connected to the additive delivery pipe by a connecting flange 131;

[0030] If the liquid cooling circulating water pipe system does not need to be descaled, close the valve A15 on the liquid inlet branch pipe 11 and the liquid discharge branch pipe 12 and open the valve B7. At this time, the liquid cooling circulating water flows normally.

[0031] When descaling the liquid cooling circulating water pipe system, open valve A15 on the liquid inlet branch pipe 11 and the liquid discharge branch pipe 12 and close valve B7. At this time, the liquid cooling circulating water flows from the liquid inlet branch pipe 11 into the descaling pipe 1, and then flows from the descaling pipe 1 through the liquid discharge branch pipe 12 back to the liquid cooling circulating water main pipe 6.

[0032] Among them, the additive delivery pipeline is connected to the discharge port of the mixing tank used for mixing reagents. In order to avoid the problem of insufficient power for delivering the mixed reagents, a booster pump can be added to the additive delivery pipeline, and the mixing tank is mainly used to prepare descaling liquid (the descaling liquid is formed by mixing antiscaling agent and deodorant in water in corresponding proportions).

[0033] In the embodiments of the present invention, please refer to Figures 1 to 6 , an injection assembly 2 is installed in the dosing branch pipe 13, and the injection assembly 2 includes an insertion pipe 21, a mounting flange 211 is fixedly installed on the top of the insertion pipe 21, the insertion pipe 21 is inserted into the dosing branch pipe 13, and a liquid injection port 21a is opened at the bottom of the insertion pipe 21, a bracket 22 is fixedly installed at the bottom of the liquid injection port 21a, and a sliding rod 23 with a sliding connection is inserted on the bracket 22, a sealing disk 24 for blocking the liquid injection port 21a is fixedly installed on the top of the sliding rod 23, and the bottom of the sliding rod 23 extends into the descaling pipe 1 and is installed with a rotatably connected steel ball 26, and the sliding rod 23 is fixed with a sealing disk 24 for blocking the liquid injection port 21a. A spring 25 is sleeved, one end of the spring 25 is fixedly connected to the lower disk surface of the sealing disk 24, and the other end of the spring 25 is fixedly connected to the upper surface of the bracket 22, and a driving component 3 for opening and closing the injection assembly 2 is installed in the descaling tube 1, and the driving component 3 includes a rotating shaft 31, the rotating shaft 31 is rotatably installed in the descaling tube 1 and is radially arranged, and a rotating wheel 32 is fixedly installed on the rotating shaft 31, and an integrally formed arc-shaped protrusion 321 is provided on the rotating wheel 32, and the outer wheel surface of the rotating wheel 32 is against the steel ball 26, and impellers 33 are fixedly installed on the rotating shaft 31 on both sides of the rotating wheel 32.

[0034] In this application, when installing the injection component 2, the insertion tube 21 is inserted into the additive branch pipe 13 and the mounting flange 211 and the connecting flange 131 are kept corresponding to each other. Then, the flange at the connecting end of the additive delivery pipe is overlapped with the mounting flange 211, and then the three flanges are fixed with bolts. If the injection component 2 needs to be maintained, the flange at the connecting end of the delivery pipe is removed and the insertion tube 21 is slid out of the additive branch pipe 13.

[0035] It should be noted that: when descaling is being performed, the impeller 33 rotates under the impact of the circulating water entering the descaling pipe 1, thereby driving the rotating shaft 31 to rotate, so that the rotating wheel 32 can rotate synchronously. When the arc-shaped protrusion 321 on the rotating wheel 32 abuts the steel ball 26, the sliding rod 23 slides up along the bracket 22 and stretches the spring 25. At this time, the sealing disk 24 no longer seals the liquid injection port 21a, so that the descaling liquid can enter the descaling pipe 1. The rotating impeller 33 enhances the mixing effect of the descaling liquid and the circulating liquid. When the arc-shaped protrusion 321 on the rotating wheel 32 no longer abuts the steel ball 26, the sealing disk 24 returns to its original position and seals the liquid injection port 21a, and the injection of the descaling liquid stops at this time.

[0036] Therefore, the mutual cooperation between the injection component 2 and the driving component 3 enables the liquid injection port 21a to be dynamically adjusted, thereby realizing the intermittent flow of the descaling agent into the descaling pipe 1, avoiding the problem of excessive concentration of local liquid cooling circulating water and insufficient concentration of descaling agent in remote liquid cooling circulating water caused by continuous addition of descaling agent, and there is no need to shut down the liquid cooling circulating water system during descaling.

[0037] It is worth noting that in order to avoid the problem that the impeller 33 cannot rotate due to insufficient impact force of the liquid cooling circulating water, a reduction motor can be added to the outside of the descaling pipe 1 to drive the rotating shaft 31 to rotate.

[0038] In order to eliminate the hidden danger of spring 25 rusting and causing elastic failure due to contact with coolant, spring 25 adopts stainless steel or titanium alloy spring to improve corrosion resistance. At the same time, polytetrafluoroethylene (PTFE) coating is applied on the surface of spring 25 to enhance rust resistance.

[0039] In the embodiments of the present invention, please refer to Figures 1 to 6 Two symmetrically distributed limiting rings 14 are fixedly installed in the descaling pipe 1, one limiting ring 14 is located in the descaling pipe 1 between the liquid inlet branch 11 and the dosing branch 13, and the other limiting ring 14 is located in the descaling pipe 1 between the liquid discharge branch 12 and the dosing branch 13;

[0040] Filter discs 4 are installed on the opposite end faces of the two limit rings 14, and a plurality of annularly distributed arc cavities 4a are opened on the filter disc 4, and a filter screen 41 is fixedly embedded in each arc cavity 4a. A threaded sleeve 42 is fixedly installed at the center of the filter disc 4, and a sealing flange 5 is fixedly installed at both ends of the descaling pipe 1, and a coaxially arranged docking screw 51 is fixedly installed on the inner disk wall of the sealing flange 5, and the docking screw 51 is threadedly fixedly connected to the threaded sleeve 42 of the corresponding filter disc 4.

[0041] It should be noted that the two filter discs 4 set up can filter impurities in the liquid cooling circulating water, further reducing the hidden danger of scale formation caused by impurities in the liquid cooling circulating water. When cleaning the filter 41, remove the sealing flange 5 and take out the filter disc 4 from the outside of the sealing flange 5, and then unscrew the filter disc 4 from the docking screw 51. The operation is simple and convenient.

[0042] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0043] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
