[0013] Embodiment 1
[0014] like Figure 1 As shown, the present application provides a device for solving the problem of large vibration of a drainage pipe, comprising:
[0015] High-pressure heater 1, electric door in front of emergency drain regulating valve 2, emergency drain regulating valve 3, manual door after emergency drain regulating valve 4, drain side bypass 5, condensate system 6, heating pipe control valve 7;
[0016] The drain outlet of the high-pressure heater 1 is connected to an electric door 2 in front of the emergency drain regulating valve, and an emergency drain regulating valve 3 is arranged downstream of the electric door 2 in front of the emergency drain regulating valve. The outlet of the emergency drain regulating valve 3 is connected to a manual door 4 behind the emergency drain regulating valve;
[0017] The drain outlet of the high-pressure heater 1 is also connected to a drain side bypass 5, and the drain side bypass 5 includes a drain side bypass valve 51;
[0018] The condensate system 6 is connected to the main pipeline corresponding to the high-pressure heater 1 through a bypass. The condensate system 6 includes a condensate inlet side isolation valve 62, a condensate outlet side isolation valve 61, and a condensate side bypass valve 63.
[0019] A heating pipe control valve 7 is provided between the electric door 2 in front of the emergency drain regulating valve and the manual door 4 behind the emergency drain regulating valve.
[0020] Electric door 2 in front of the emergency drain regulating valve: This electric door is directly connected to the drain outlet of the high-pressure heater 1. Its main function is to control the passage of drain from the high-pressure heater 1 to the electric door 2 in front of the emergency drain regulating valve. During normal operation, the door remains open; in an emergency, it can be remotely controlled to close quickly and cut off the drain flow.
[0021] Emergency drain regulating valve 3: This regulating valve is connected downstream of the electric gate 2 in front of the emergency drain regulating valve. It is used to accurately adjust the drain flow according to system requirements. The outlet of the emergency drain regulating valve 3 is connected to the manual gate 4 after the emergency drain regulating valve.
[0022] Manual gate 4 after the emergency drain regulating valve: This manual gate is located downstream of the emergency drain regulating valve 3. In normal operation, this gate remains open, allowing the regulated drain to continue to flow to the downstream system. When inspection or maintenance is required, the staff can manually close this gate to isolate the downstream system.
[0023] Drain side bypass 5: This bypass is connected to the drain outlet of the high-pressure heater 1, and is located between the upstream and downstream of the drain system. It serves as a backup path so that when the main drain path fails or is maintained, the drain can continue to flow through the bypass. The drain side bypass 5 includes a drain side bypass 5 valve for controlling the on and off of the bypass.
[0024] Condensate system 6: This system includes components such as the condensate inlet isolation valve 62, the condensate outlet isolation valve 61, and the condensate bypass valve 63, which control the inlet, outlet, and bypass flow of condensate. These valves are relatively independent of the drain system, but work together to ensure the normal operation of the entire heating and drain system.
[0025] Preferably, the heating pipe control valve 7 includes a heating pipe primary door 71 and a heating pipe secondary door 72. The heating pipe primary door 71 is placed on the side of the electric door 2 in front of the emergency drain regulating valve away from the high-pressure heater 1, and the heating pipe secondary door 72 is placed on the side of the manual door 4 behind the emergency drain regulating valve close to the emergency drain regulating valve 3.
[0026] Before opening the emergency drain regulating valve, it is necessary to slowly open the heating pipe primary door 71 and the heating pipe secondary door 72 to allow a small amount of fluid to flow through to preheat the pipe and the regulating valve. This can prevent thermal stress caused by excessive temperature difference and protect the safety of equipment and pipelines.
[0027] During the use of pipe heating, it is necessary to closely monitor the temperature and pressure changes of the pipes and valves. Once an abnormal situation is found, the pipe heating door should be closed immediately and corresponding treatment should be carried out. After confirming that the pipe heating effect is good, the high-pressure heater emergency drain valve can be gradually opened, and the opening of the primary and secondary doors of the pipe heating can be adjusted to maintain a stable flow of drain.
[0028] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
