[0002] Compressed air has many uses. In thermal power plants, compressed air is used for transmission, cleaning, pneumatic execution, pushing pointers, executing adjustments, driving machinery, switches and sensors, etc. In the process of producing and transporting compressed air, condensed water is inevitably produced. In related technologies, condensed water in compressed air is usually discharged through steam traps. However, steam traps need to accumulate a certain amount of water before discharging condensed water. In winter, when the temperature is low, the undischarged water may freeze in the pipes and block the pipes, resulting in poor drainage. Steam traps are also at risk of freezing and cracking.

[0029] Please refer to Figure 1 to Figure 2 The utility model proposes a compressed air drain device 1000, including an air inlet pipe 1, a water collector 2, a main water outlet pipe 3, a water trap 4 and a secondary water outlet pipe 5; the water collector 2 is arranged at the lower end of the air inlet pipe 1; the main water outlet pipe 3 is arranged at the bottom of the water collector 2; the water trap 4 is arranged at one end of the main water outlet pipe 3 away from the water collector 2, and the water trap 4 is used to discharge the accumulated water in the water collector 2; the secondary water outlet pipe 5 is arranged at one end of the water collector 2 away from the air inlet pipe 1.
[0030] In the technical solution of the utility model, when compressed air enters the water collector 2 through the air inlet pipe 1, the condensed water in the compressed air will adhere to the inner wall of the water collector 2 or fall to the bottom of the water collector 2 under the action of gravity. After a certain amount of water has accumulated, it will be automatically discharged from the water trap 4 through the main water outlet pipe 3. When the temperature is low in winter, the water in the water collector 2 can be discharged through the secondary water outlet pipe 5. Since the water collector 2 is located at the lower end of the air inlet pipe 1, and the secondary water outlet pipe 5 is located at the lower end of the water collector 2, the water in the water collector 2 can be directly discharged through the secondary water outlet pipe 5 under the action of gravity, and will not accumulate in the water collector 2, thereby avoiding the situation where the condensed water freezes and blocks the drainage, thereby ensuring normal drainage.
[0031] Further, in one embodiment of the present invention, the compressed air drain device 1000 further includes a first switch valve 6, which is disposed on the main water outlet pipe 3. The first switch valve 6 can be selected from different types of valves according to actual use requirements, such as an electric ball valve, an electric butterfly valve, or an electric gate valve, etc., and is not specifically limited. The relevant staff can remotely control the on-off of the first switch valve 6 or set a preset period on-off to discharge the water in the water collector 2 through the steam trap 4.
[0032] Similarly, in one embodiment of the present invention, the compressed air drain device 1000 further includes a second switch valve 7, which is disposed on the secondary outlet pipe 5. The second switch valve 7 can be selected from different types of valves according to actual use requirements, such as an electric ball valve, an electric butterfly valve, or an electric gate valve, etc., without specific limitation. When the temperature is low in winter, the first switch valve 6 can be closed manually or by remote control, and the second switch valve 7 can be opened at the same time, so that the water in the water collector 2 can be directly discharged through the secondary outlet pipe 5, and will not accumulate in the water collector 2, thereby avoiding the situation where condensed water accumulates in the water collector 2 and freezes, and ensuring smooth drainage.
[0033] In order to ensure the sealing of the connection, in one embodiment of the utility model, the compressed air drain device 1000 further includes a flange 8, which is detachably arranged at one end of the water collector 2 away from the air inlet pipe 1, and the secondary water outlet pipe 5 is arranged at a side of the flange 8 away from the water collector 2. By connecting the water collector 2 and the secondary water outlet pipe 5 through the flange 8, the sealing of the connection between the water collector 2 and the secondary water outlet pipe 5 can be ensured, and the secondary water outlet pipe 5 can also be easily disassembled or replaced.
[0034] Specifically, in one embodiment of the utility model, the compressed air drain device 1000 also includes a connecting pipe 9, one end of which is connected to the air inlet pipe 1, and the other end of the connecting pipe 9 is connected to the water collector 2, and the cross-sectional area of the connecting pipe 9 gradually increases from one end of the connecting pipe 9 to the other end of the connecting pipe 9. In this way, when selecting the water collector 2, a water collector 2 with a larger diameter can be selected, which can increase the capacity of the water collector 2 and collect more condensed water. In addition, in order to ensure sealing, the two ends of the connecting pipe 9 are respectively welded to the air inlet pipe 1 and the water collector 2.
[0035] In order to improve practicality, in one embodiment of the present invention, the compressed air drain device 1000 further includes an air outlet pipe 10, which is arranged at one side of the water collector 2, so that when needed, the compressed air can be transmitted through the air outlet pipe 10 for use. The air outlet pipe 10 is located above the main water outlet pipe 3 and parallel to the main water outlet pipe 3. In this way, since the condensed water accumulates at the bottom of the water collector 2, the water content of the compressed air transmitted by the air outlet pipe 10 can be reduced. In addition, the space occupied by the compressed air drain device 1000 can be reduced, which is convenient for installation and use.
[0036] Furthermore, in one embodiment of the present invention, the compressed air drain device 1000 further includes an outlet valve 11, which is disposed on the outlet pipe 10. The outlet valve 11 can be selected from different types of valves according to actual use requirements, such as an electric ball valve, an electric butterfly valve, or an electric gate valve, etc., and the specifics are not limited thereto. The relevant staff can remotely control the on and off of the outlet valve 11 to control the output of the outlet pipe 10.
[0037] Furthermore, in one embodiment of the present utility model, the compressed air drain device 1000 further includes an air intake valve 12, which is arranged on the air intake pipe 1. The air intake valve 12 can be an electric ball valve, an electric butterfly valve or an electric gate valve, etc. In this embodiment, an electric ball valve is selected, and the relevant staff can remotely control the opening and closing of the air intake valve 12 to control the compressed air to enter the water collector 2. In order to ensure the sealing performance, the air intake valve 12 is welded to the air intake pipe 1 through a flange.
[0038] In order to ensure the normal operation of the steam trap 4, in one embodiment of the utility model, the compressed air steam trap device 1000 further includes a filter 13, which is arranged in the main outlet pipe 3, and the filter 13 is located between the water collector 2 and the steam trap 4. The filter 13 is used to filter impurities in the accumulated water flowing through the main outlet pipe 3. By providing the filter 13, impurities in the accumulated water can be prevented from entering the steam trap 4, reducing the clogging of the steam trap 4. At the same time, the impurities filtered out by the filter 13 are manually cleaned regularly to ensure the normal operation of the filter 13.
[0039] In order to drain water in time, in one embodiment of the utility model, the compressed air drain device 1000 further includes a liquid level detector, which is arranged in the water collector 2 and is used to detect the amount of water in the water collector 2. The liquid level detector is located at the bottom of the water collector 2, and the amount of water in the water collector 2 can be detected in real time through the liquid level detector. The liquid level detector can establish a communication connection with the first switch valve 6. When the liquid level detector detects that the amount of water in the water collector 2 reaches a preset value, the first switch valve 6 is controlled to open, and then the water is drained in time through the steam trap 4.
