Specifically, the air inlet of the steam-water separator 300 is communicated with a vacuum pump unit, and the vacuum pump unit pumps moisture in the condenser 400 into the steam-water separator 300, so that the condenser 400 is vacuumized by the vacuum pump unit and is in a vacuum state. Moisture is separated in the steam-water separator 300, wherein the separated gas is discharged through an upper exhaust port, and the separated water is collected at a lower portion and can be discharged through a water discharge port of the steam-water separator 300, and the water discharge mode of the water discharge port is described in detail later.
The monitor 200 is electrically connected to the vacuum pump set to obtain an operation parameter of the vacuum pump set, which may be a current magnitude of the vacuum pump set during operation. During normal operation, the vacuum pump group is used for keeping the vacuum state of condenser 400, and the current value of vacuum pump group is stable this moment, and when condenser 400 appeared leaking, the load increase of vacuum pump group, and the current value when its operation also will appear great fluctuation, when monitor 200 detected this kind of fluctuation, can judge that condenser 400 appeared leaking to the staff in time takes intervention measure.
It can be seen that, the evacuation pipe-line system of this application, make full use of the setting of vacuum pump package, not only realize the evacuation to condenser 400 through vacuum pump package, through the running state who inserts monitor 200 monitoring vacuum pump package moreover, can in time judge condenser 400 whether appear leaking to guarantee entire system's even running.
The vacuum pump set includes a first vacuum pump 110 and a roots pump 120, the first vacuum pump 110 is typically a water ring vacuum pump, and the roots pump 120 is typically an air-cooled roots pump. The first vacuum pump 110 is used as a backing pump of the roots pump 120 to prevent the roots pump 120 from being damaged due to overload or overheating, and in use, the first vacuum pump 110 first pumps the inlet pressure to the inlet pressure allowed by the roots pump 120, and then the roots pump 120 is started, and then the first vacuum pump 110 and the roots pump 120 are operated in series.
Specifically, the condenser 400, the roots pump 120, the first vacuum pump 110, and the steam-water separator 300 are sequentially communicated, and moisture in the condenser 400 is sequentially pumped to the steam-water separator 300 by the roots pump 120 and the first vacuum pump 110 to be treated.
The monitor 200 is electrically connected to the roots pump 120 to obtain the operating current of the roots pump 120. As shown in fig. 2, the monitor 200 detects the main roots blower current and the secondary roots blower current in the roots pump 120 at the same time, when the condenser 400 leaks, the main roots blower current and the secondary roots blower current fluctuate to a greater extent, and the worker can know that the leakage occurs immediately, so as to take intervention measures in time.
Further, the first vacuum pump 110 and the roots pump 120 are each independently driven by a motor to ensure respective independent operations without interfering with each other.
Further, the evacuation piping system may further include a first heat exchanger 500. The inlet of the first heat exchanger 500 is communicated with the outlet of the roots pump 120, and the outlet of the first heat exchanger 500 is communicated with the inlet of the first vacuum pump 110. The first heat exchanger 500 may be a tubular heat exchanger to cool the roots pump 120 and prevent the roots pump 120 from generating abnormal conditions such as overload heat.
Further, the evacuation piping system may further include a second heat exchanger 600. The second heat exchanger 600 is communicated with the liquid inlet of the first vacuum pump 110. The second heat exchanger 600 may be a plate heat exchanger to cool the first vacuum pump 110, and avoid the first vacuum pump 110 from generating abnormal conditions such as overload heating.
Further, the first water discharge port of the steam-water separator 300 is communicated with the liquid inlet of the first vacuum pump 110 through the second heat exchanger 600. After the moisture pumped into the steam-water separator 300 by the first vacuum pump 110 is treated, the separated water flows back to the second heat exchanger 600 from the first drain port to be used as working water of the second heat exchanger 600, so that the purpose of saving energy is achieved.
Further, the steam-water separator 300 may further have a second water outlet, the second water outlet is communicated with the water discharge main pipe 700, and a water discharge control valve 310 is disposed between the water discharge main pipe 700 and the second water outlet. In a specific use, if the water separated by the steam-water separator 300 is relatively small, the drain control valve 310 is closed to completely return the water to the second heat exchanger 600; and if the water separated by the steam-water separator 300 is more, the drain control valve 310 is opened, so that a part of the water generated by the steam-water separator 300 is returned to the second heat exchanger 600, and the rest part of the water is discharged through the water discharge main pipe 700, thereby saving energy and better meeting the working requirements of the whole vacuum pumping pipeline system.
Further, the vacuum pumping pipeline system may further include a vacuum breaking device 800. The air inlet of the roots pump 120 is respectively communicated with the condenser 400 and the vacuum breaking device 800. The vacuum breaking device 800 can be a vacuum breaking pipeline provided with a vacuum breaking valve, the vacuum breaking pipeline is connected to an air inlet pipe of the roots pump 120, when the roots pump 120 stops, the vacuum breaking valve is opened, external air is introduced, the vacuum breaking device 800 breaks vacuum automatically, and after the time delay of 30 seconds, the first vacuum pump 110 stops working.
Further, the evacuation piping system may further include a second vacuum pump 900.

In this arrangement, the roots pump 120 is used in a normal condition to maintain the vacuum state of the condenser 400, and the roots pump 120 continuously pumps moisture generated by the condenser 400, so that the rated power of the roots pump 120 is small. The second vacuum pump 900 is used when the condenser 400 is abnormal to extract moisture leaked from the condenser 400, so that the rated power of the second vacuum pump 900 is greater than that of the roots pump 120.
Specifically, during normal operation, the second vacuum pump 900 and the second control valve 910 are stopped, and the first vacuum pump 110, the roots pump 120, and the first control valve 130 are opened to continuously pump moisture generated by the condenser 400 and maintain the vacuum degree of the condenser 400.
When the condenser 400 leaks, the monitor 200 detects that the operating current of the roots pump 120 fluctuates, at this time, the first vacuum pump 110, the roots pump 120 and the first control valve 130 are all closed, and the second vacuum pump 900 and the second control valve 910 are all started, so that moisture leaking into the condenser 400 is pumped out and is pumped into the steam-water separator 300 for treatment.
