[0024] It should be noted that three groups of water vapor separation mechanisms correspond to the steam low pressure, medium pressure and high pressure in steam condensate pipe 101 respectively, and the selection and specifications of all components and devices in three groups of water vapor separation mechanisms are different for different steam pressure states, for example, some conveying pipes included in three groups of water vapor separation mechanisms, the pipe diameter and wall thickness of these pipes are set according to the corresponding steam pressure state to be processed, when high pressure steam is processed, the pipe diameter of conveying pipe in corresponding water vapor separation mechanism is relatively large, and the wall thickness is relatively thick, so that the risk of pipe leakage or burst can be relatively reduced, so that steam condensate under different pressure states can be processed more efficiently.

[0025] Please refer to Figure 2 Each water vapor separation mechanism includes electromagnetic valve 111, one end of electromagnetic valve 111 is connected with corresponding four-way shunt pipe 103 shunt port, one end of first connecting pipe 104 is connected with the other end of electromagnetic valve 111, one end of steam trap 105 is connected with the other end of first connecting pipe 104, one end of second connecting pipe 106 is connected with the other end of steam trap 105, the other end of second connecting pipe 106 is connected with collecting pipe 107.

[0026] The electromagnetic valve 111 is selected to have a fast response speed and good sealing performance. Different specifications of the electromagnetic valve 111 are selected according to the steam pressure state to be treated. The electromagnetic valve 111 is tightly connected with the first connecting pipe 104 through a flange to ensure no steam leakage. The first connecting pipe 104 is a seamless steel pipe. The diameter of the first connecting pipe 104 is designed according to the steam flow. The inner wall of the first connecting pipe 104 is smooth to reduce frictional resistance. One end of the first connecting pipe 104 is connected with the electromagnetic valve 111. The other end of the first connecting pipe 104 is welded or flange-connected with the steam trap 105. The steam trap 105 is selected to have a proper type according to the system pressure range, such as a float ball type or a thermal power type. The steam trap 105 is installed at a position convenient for drainage and maintenance. The drainage port of the steam trap 105 is accurately connected with the second connecting pipe 106 to ensure that the condensed water is smoothly discharged.

[0028] The third connecting pipe 109 is selected to be a flexible high-temperature-resistant pipe, such as a metal bellows. One end of the third connecting pipe 109 is communicated with the outer wall of one side of the first connecting pipe 104 through a flange or a quick connector to ensure that the connection is tight and does not affect the normal flow of the steam condensate in the first connecting pipe 104. The other end of the third connecting pipe 109 is also communicated with the return pipe 110 in a reliable manner. When collecting steam condensate, the water enters the second connecting pipe 106 through the steam trap 105.

The wires between the pressure gauge 102 and the control panel 5 are arranged according to the wiring specifications to ensure stable transmission of the pressure signal. The signal receiving module in the control panel 5 analyzes the received pressure data in real time. The pressure gauge 102 monitors the steam pressure in the steam condensate pipe 101 in real time, and divides the steam pressure into low, medium and high pressure according to the preset value. The control panel 5 automatically opens or closes the corresponding electromagnetic valve 111 according to the pressure value detected by the pressure gauge 102. For example, when the steam pressure in the steam condensate pipe 101 is medium, the control panel 5 automatically closes the electromagnetic valves 111 in the low-pressure and high-pressure water vapor separation mechanisms, so that the steam and condensate can only enter the medium-pressure water vapor separation mechanism for processing.
