[0034] Example

[0035] An embodiment of the present application provides a dry cooling device, which includes a medium pipeline 10, a heat exchange component and an air intake pipeline 50. The medium pipeline 10 has a first inlet, and the first inlet is used to supply a series washing medium to enter the medium pipeline 10; the heat exchange component includes a cooler 20, and cooling water flows in the cooler 20. The medium pipeline 10 is penetrated by the cooler 20. The cooling water of the cooler 20 is used to exchange heat with the series washing medium in the medium pipeline 10 to reduce the temperature of the series washing medium in the medium pipeline 10; the air intake pipeline 50 is connected to the medium pipeline 10, and the air intake pipeline 50 is used to introduce gas into the medium pipeline 10.

[0036] In this solution, by setting the cooler 20, even during the series washing process, due to the work of the system power facility, the cooler 20 can provide water cooling function for the series washing medium in the medium pipeline 10, reduce the temperature of the series washing medium, avoid the series washing medium temperature being too high during the series washing process, and thus realize continuous series washing of the pipeline. More importantly, by setting the air intake pipeline 50, the air intake pipeline 50 can introduce gas into the series washing medium. According to the gas-liquid two-phase flow principle, during the series washing process, the bursting of gas-phase bubbles helps to take away impurities attached to the inner wall of the pipeline, realize gas-liquid two-phase series washing, and effectively improve the series washing efficiency and series washing effect of the pipeline.

[0037] The washing medium is in liquid phase. After gas is introduced into the washing medium through the setting of the air inlet pipeline 50, gas-liquid two-phase washing is realized. The cooler 20 is a water cooling device. The cooling water and the washing medium in the medium pipeline 10 are used to realize heat exchange, thereby reducing the temperature of the washing medium. In this way, after the washing medium enters the washing pipeline and completes one washing, it can enter the medium pipeline 10 again, and after heat exchange in the cooler 20, continuous washing of the pipeline is realized.

[0038] In some embodiments, along the flow direction of the washing medium in the medium pipeline 10, the air intake pipeline 50 is connected to the downstream end of the cooler 20 on the medium pipeline 10. By connecting the air intake pipeline 50 to the downstream end of the cooler 20 in the medium pipeline 10, the gas introduced into the air intake pipeline 50 is mixed with the cooled washing medium, and the gas-liquid two-phase mixture enters the washing pipeline again, and the pipeline is continuously washed.

[0039] In some embodiments, the drying and cooling device further includes a junction box 30 and an online monitoring device 40, the online monitoring device 40 is electrically connected to the junction box 30, the online monitoring device 40 is arranged at the downstream end of the cooler 20 of the medium pipeline 10, and the online monitoring device 40 is used to monitor the particle contamination and moisture level of the series washing medium in the medium pipeline 10. Through the arrangement of the online monitoring device 40 and the junction box 30, the online monitoring device 40 can monitor the clean state of the series washing medium before it enters the series washing pipeline again in real time, and then judge the clean state of the pipeline, which plays an auxiliary role in judging the cleanliness of the pipeline, and does not need to be judged manually, and the degree of automation is higher.

[0040] If the online monitoring device 40 detects that the clean state of the washing medium is good and the clean state meets the preset requirements, it means that the clean state of the pipeline is good and it is not necessary to wash again. If the online monitoring device 40 detects that the clean state of the washing medium is poor, it means that there are a lot of impurity particles in the pipeline, and it is necessary to continue washing the pipeline until the cleanliness of the washing medium in the medium pipeline 10 meets the preset requirements, and then the continuous washing of the pipeline can be stopped.

[0041] The junction box 30 has a built-in controller, and the junction box 30 is electrically connected to the controller through a signal line. The data monitored by the online monitoring device 40 will be fed back to the controller, and the controller will transmit the data to the background, so that the staff can check the working status of the drying and cooling device in real time.

[0042] In some embodiments, along the flow direction of the series washing medium in the medium pipeline 10, a first temperature sensor 12 is provided on the medium pipeline 10 at the upstream end of the cooler 20, and the first temperature sensor 12 is used to monitor the temperature of the medium in the medium pipeline 10 before entering the cooler 20. By providing the first temperature sensor 12 on the upstream end of the cooler 20 on the medium pipeline 10, the first temperature sensor 12 can monitor the temperature of the series washing medium in the medium pipeline 10 before entering the cooler 20, so as to monitor the temperature of the series washing medium in advance.

[0043] In some embodiments, a second temperature sensor 13 is provided on the medium pipeline 10 at the downstream end of the cooler 20, and the second temperature sensor 13 is used to monitor the temperature of the medium in the medium pipeline 10 after being cooled by the cooler 20. The first temperature sensor 12 and the second temperature sensor 13 are both electrically connected to the junction box 30. By providing the second temperature sensor 13 on the downstream end of the cooler 20 on the medium pipeline 10, the second temperature sensor 13 can monitor the temperature of the series washing medium in the medium pipeline 10 after being cooled by the cooler 20, determine whether the power of the cooler 20 meets the requirements, and realize the temperature monitoring of the series washing medium before and after the cooling.

[0044] When the temperature monitored by the second temperature sensor 13 is lower than the preset value, it means that the cooling effect of the cooler 20 on the series washing medium is good. When the temperature monitored by the second temperature sensor 13 is higher than the preset value, it means that the cooling effect of the cooler 20 on the series washing medium is poor, or the initial temperature of the series washing medium is too high, so that the staff can take timely measures to adjust the power of the cooler 20 according to the temperature of the series washing medium.

[0045] The junction box 30 provides power supply for the first temperature sensor 12, the second temperature sensor 13 and the online monitoring device 40. The first temperature sensor 12, the second temperature sensor 13 and the online monitoring device 40 transmit the signal to the controller in the junction box 30 through the cable, and the signal is processed by the junction box 30 and then transmitted to the background.

[0047] In some embodiments, a first valve 22 is provided between the external cooling water pipeline and the cooling water filter 21, and a second valve 23 is provided on the external cooling water pipeline downstream of the liquid outlet of the cooler 20. By providing the first valve 22 between the external cooling water pipeline and the cooling water filter 21, the introduction control of cooling water in the cooler 20 can be achieved by controlling the first valve 22. By providing the second valve 23 downstream of the liquid outlet of the cooler 20 through the external cooling water pipeline, the discharge of cooling water in the cooler 20 can be controlled. The first valve 22 and the second valve 23 are controlled together, and the cooling water in and out of the cooler 20 can be controlled according to the cooling effect of the series washing medium and the working state of the cooler 20.

[0048] The first valve 22 and the second valve 23 may be manual valves or solenoid valves. When the first valve 22 and the second valve 23 are solenoid valves, the first valve 22 and the second valve 23 are electrically connected to the junction box 30, and the controller in the junction box 30 may automatically control the opening and closing of the first valve 22 and the second valve 23.
