This utility model relates to the field of boiler technology and discloses a steam-water separation device for a Class D boiler. It includes a boiler body and an evaporator tube located inside the furnace chamber. A lower header is located at the bottom of the boiler body, and an upper header is located at the top. The upper and lower ends of the evaporator tube are connected to the upper and lower headers, respectively. The evaporator tube contains saturated water, and a steam-water separation device is located at the top of the evaporator tube, with a gap between the device and the water surface below it. Steam rises and enters a spiral steam channel, rotating rapidly upwards along the channel. Tiny water droplets in the steam, under the influence of gravity and centrifugal force, detach from the steam and fall back into the evaporator tube, significantly reducing the water content in the steam and achieving steam-water separation. This improves the quality of the steam and alleviates abnormal water level fluctuations in the heat exchange tubes. The collected water droplets reduce the supply of saturated water in the evaporator tubes to a certain extent, effectively saving energy and water resources.

The application discloses a spacecraft formation event-triggered attitude coordination control method considering communication time delay, comprising the following steps: according to the communication topology structure of a spacecraft formation system, an attitude dynamics model of the spacecraft formation is established, which can consider external disturbance, model uncertainty and communication time delay; based on the attitude dynamics model, a nonlinear observer is constructed, which can observe the collective nonlinear term of the spacecraft formation system; based on the nonlinear observer, an event-triggered attitude coordination control law and an event-triggering mechanism are designed; according to the event-triggered attitude coordination control law, the attitude and angular velocity of the formation spacecraft are controlled, and according to the event-triggering mechanism, it is determined whether the corresponding event-triggered attitude coordination control law of the formation spacecraft needs to be updated and whether the state information of the formation spacecraft needs to be sent to the adjacent formation spacecraft. The application can consider the influence of disturbance, uncertainty and communication time delay, save the energy, communication and computing resources of the system while ensuring good control performance.
