Technical Field

[0002] Power plants often use demineralized water as cooling water for various equipment. Since demineralized water absorbs a large amount of heat during use, it cannot be reused many times. The used demineralized water can only be wasted in vain, and new demineralized water must be replaced, resulting in a huge waste of resources.

[0003] For example, the desalted water cooling device disclosed in Patent No. CN103245231A cools the desalted water after use and uses low-cost industrial water to cool the high-cost desalted water so that the desalted water can be recycled in the system to reduce the operating cost of the system. It has the characteristics of simple structure, easy use and low operating cost, and is suitable for popularization and use. However, in actual use, the temperature of the desalted water entering the desalted water tank decreases due to its storage time, so that there is a temperature difference between the desalted water and the desalted water added subsequently, resulting in uneven water temperature in the water layer in the desalted water tank. Therefore, the water temperature of the desalted water discharged through the heat exchanger is different, and it is impossible to better ensure that the outlet water temperature of the desalted water meets the subsequent process requirements.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0023] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0024] like Figure 1 As shown, a desalted water cooling skid-mounted equipment in this embodiment includes a base plate 10 and a desalted water tank 100 and a heat exchanger (not shown in the figure) arranged on the base plate 10. A water inlet pipe 101 located at the top and a water outlet pipe 102 located at the bottom are provided on the side wall of the desalted water tank 100. The water outlet pipe 102 is connected to the heat exchanger through a water pipe. The water pipe is provided with a circulating pump 20 for pumping the desalted water in the desalted water tank 100 into the heat exchanger. A stirring component for stirring the desalted water is also provided in the desalted water tank 100.

[0025] Through the structure of this embodiment, the desalted water with a higher temperature is input into the desalted water tank 100 through the water inlet pipe 101, and the circulating pump 20 is arranged so that the circulating pump 20 can pump the desalted water with a higher temperature in the desalted water tank 100 into the heat exchanger through the water outlet pipe 102 and the water pipe. The heat exchanger is an existing structure. When it is actually used, the circulating cooling water flows into the heat exchanger through the cooling water inlet of the heat exchanger, and the desalted water enters through the desalted water inlet of the heat exchanger, so that heat exchange is performed between the cooling water and the desalted water with a higher temperature, so that the desalted water outputted by the heat exchanger is cooled.

[0026] When this embodiment is actually used, the temperature of the desalted water entering the desalted water tank 100 decreases due to its storage time, resulting in a temperature difference between the desalted water and the desalted water continuously injected from the upper water inlet pipe 101, thereby causing the water temperature of the water layer in the desalted water tank 100 to be uneven, that is, causing the water temperature of the desalted water discharged through the heat exchanger to be different, thereby failing to ensure that the outlet water temperature of the desalted water can meet subsequent process requirements; in this embodiment, through the provision of a stirring component, the stirring component can stir the desalted water in the desalted water tank 100, so that the desalted water in the desalted water tank 100 is fully flow mixed, thereby avoiding the phenomenon of uneven water temperature of the water layer in the desalted water tank 100, so as to ensure the outlet water temperature of the subsequent desalted water.

[0027] Combination Figure 2-6 As shown, in this embodiment, the agitator assembly includes relatively arranged mounting frames 200, a rotatable first rotating shaft 210 is provided between the mounting frames 200, first agitator plates 211 are evenly arranged on the side walls of the first rotating shaft 210, support plates 212 are oppositely provided at both ends of the first rotating shaft 210, a rotatable second rotating shaft 220 is provided between the opposite ends of the support plates 212, second agitator plates 221 extending between adjacent first agitator plates 211 are evenly arranged on the second rotating shaft 220, gears 222 are provided at both ends of the second rotating shaft 220, and an annular gear ring 230 matching the corresponding gear 222 is provided on the mounting frame 200 along its circumference.

[0028] In actual use of this embodiment, the mounting frame 200 is annular and fixedly mounted in the demineralized water tank 100, thereby preferably achieving the installation of the flow stirring assembly in the demineralized water tank 100;

[0029] Among them, by the arrangement of the first rotating shaft 210 and the first stirring plate 211, the rotation of the first rotating shaft 210 can drive the first stirring plate 211 to drive the desalted water in the desalted water tank 100 to flow. At the same time, by the arrangement of the second rotating shaft 220 and the second stirring plate 221, in actual use, the second stirring plate 221 extends between the adjacent first stirring plates 211, so that the rotation of the second rotating shaft 220 can drive the second stirring plate 221 to rotate, and stir the desalted water in the stirring blind area of ​​the first stirring plate 211, so that the stirring assembly has a better stirring and mixing effect on the desalted water in the desalted water tank 100;

[0030] Among them, by setting the support plate 212, the gear 222 and the annular gear ring 230, in actual use, the inner side wall of the annular gear ring 230 is evenly provided with tooth grooves that match the corresponding gear 222, so that the rotation of the first rotating shaft 210 can drive the support plate 212 to rotate, that is, the second rotating shaft 220 can rotate along the first rotating shaft 210. At the same time, due to the cooperation of the gear 222 and the tooth groove, the second rotating shaft 220 can also rotate on its own, that is, the rotation of the first rotating shaft 210 can drive the second rotating shaft 220 to revolve around it and rotate on its own, so that the stirring component has a better stirring and mixing effect on the desalted water in the desalted water tank 100;

[0031] The first rotating shaft 210 and the second rotating shaft 220 are both rotatably mounted on the mounting frame 200 through bearings, so that the first rotating shaft 210 and the second rotating shaft 220 can be rotatably mounted.

[0032] Combination Figure 3-5 As shown, in this embodiment, a removable top cover 110 is provided at the upper end of the desalted water tank 100, and a rotatable drive shaft 440 is provided on the top cover 110; the upper end of the first rotating shaft 210 passes through the mounting frame 200, and the protruding end of the first rotating shaft 210 is provided with a drive assembly for cooperating with the drive shaft 440.

[0033] In actual use of this embodiment, the top cover 110 is detachably mounted on the upper end of the desalted water tank 100 by bolts, wherein, by setting the drive shaft 440 and the drive assembly, when the top cover 110 is mounted on the desalted water tank 100, the drive shaft 440 thereon cooperates with the protruding end of the first rotating shaft 210 through the drive assembly, that is, the rotation of the drive shaft 440 can drive the first rotating shaft 210 to rotate through the drive assembly, thereby realizing the operation of the agitation assembly;

[0034] The top cover 110 is provided with a motor 111 for driving the driving shaft 440 to rotate, thereby enabling the motor 111 to drive the first rotating shaft 210 to rotate, thereby realizing the operation of the agitation component.

[0035] Combination Figure 6 As shown, in this embodiment, the driving assembly includes a driving cylinder 310, the upper end of the first rotating shaft 210 is fixedly connected to the lower end of the driving cylinder 310, a plug 410 is provided at the upper end opening of the driving cylinder 310, a sliding column 430 is provided in the driving cylinder 310 through a spring 420, and a driving column 431 extending through the plug 410 is provided on the sliding column 430, and a sliding groove 401 is provided on the inner side wall of the driving cylinder 310 along its axial direction, and a sliding block extending into the corresponding sliding groove 401 is provided on the side wall of the sliding column 430, and a groove is provided at the protruding end of the driving column 431, and a protrusion 511 extending into the groove is provided at the lower end of the driving shaft 440.

[0036] In this embodiment, the plug 410 is connected to the upper end opening of the driving cylinder 310 by threading, and is used to block the driving cylinder 310, thereby preferably realizing the disassembly and assembly of the spring 420 and the sliding column 430 in the driving cylinder 310;

[0037] The slide groove 401 and the slider are matched to each other so that the slider is inserted into the corresponding slide groove 401 and slides, so that a key groove is formed between the slide column 430 and the drive cylinder 310, that is, the rotation of the slide column 430 can drive the drive cylinder 310 to drive the first rotating shaft 210 to rotate;

[0038] Among them, through the arrangement of the spring 420, the driving column 431, the groove and the protrusion 511, in actual use, the spring 420 drives the driving column 431 to extend out of the driving cylinder 310. When the top cover 110 is installed at the upper end of the desalted water tank 100, the lower end of the driving shaft 440 abuts against the driving column 431. Since the protrusion 511 can be inserted into the groove, the rotation of the driving shaft 440 can drive the driving column 431 to rotate, thereby realizing its driving of the first rotating shaft 210 to rotate. At the same time, with the contraction of the spring 420, when the top cover 110 is installed, there is no need to deliberately align the driving shaft 440 and the driving column 431. The driving shaft 440 and the driving column 431 can be matched, thereby driving the first rotating shaft 210 to rotate, thereby making it easier to disassemble and assemble the top cover 110.

[0039] Working principle: Desalted water with a relatively high temperature is continuously input into the desalted water tank 100 through the water inlet pipe 101, and then the motor 111 is started to drive the first rotating shaft 210 and the second rotating shaft 220 to rotate, so that the first stirring plate 211 and the second stirring plate 221 can stir and mix the desalted water in the desalted water tank 100. At the same time, the circulating pump 20 is started to transport the desalted water in the desalted water tank 100 to the heat exchanger for heat exchange. The desalted water after heat exchange is discharged from the heat exchanger to complete the cooling process of the desalted water.
