Gland steam exhauster drains into atmosphere, to guarantee the vacuum state in condenser.
Thermal power plant's evacuation system for steam condenser uses unit style at present.Under normal conditions, be equipped with two of single unit are true
Sky pump, when a vacuum pump failure is overhauled, another appendage vacuum pump starting continues to keep taking out condenser vacuum.If one
When platform vacuum pump failure is overhauled, also catastrophic failure loses suction capactity to another appendage vacuum pump, then evacuation system for steam condenser
It is ineffective, power plant units can be caused to stop transport when serious.
Summary of the invention
The purpose of this utility model is to solve the above problems, and provides a kind of condenser parallel connection vacuum evacuation device, by adjacent machine
The condenser vacuum evacuation device connection of group, improves the availability of condenser vacuum evacuation device, reduces the event of condenser vacuum evacuation device
Hinder and cause the risk of unit outage.
The technical solution of the utility model is a kind of condenser parallel connection vacuum evacuation device, including the first exhaust pipe, second
Exhaust pipe, further includes sequentially connected first isolating valve, pneumatic operated valve, the second isolating valve, the first isolating valve other end with
The connection of first exhaust pipe, the second isolating valve other end are connect with the second exhaust pipe, and the first exhaust pipe is true with first respectively
Sky pump, the connection of the second vacuum pump, the second exhaust pipe are connect with third vacuum pump.
The condenser parallel connection vacuum evacuation device includes controller and difference first pressure sensor connected to it, second
Pressure sensor, first pressure sensor are set in the first exhaust pipe, and second pressure sensor is set to the second exhaust tube
Lu Zhong；Controller is connect with pneumatic operated valve control terminal.
The condenser parallel connection vacuum evacuation device further includes combined aural and visual alarm, and combined aural and visual alarm is connect with controller.
The condenser parallel connection vacuum evacuation device further includes the 4th vacuum pump, and the 4th vacuum pump and the second exhaust pipe connect
It connects.
The utility model has the beneficial effects that
1) by way of condenser vacuum evacuation device parallel running, the reliability of evacuation system for steam condenser is improved,
To the security implication of operating unit when effectively avoiding the vacuum pump simultaneous faults of single unit；
2) two units in parallel occur simultaneously vacuum evacuation device operation it is unsmooth when, issue alarm signal, remind relevant people
Member takes measures；
3) when unit maintenance, vacuum evacuation device can be separated by isolating valve, avoids single unit maintenance to another
Unit has an impact.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of condenser parallel connection vacuum evacuation device, including the first exhaust pipe 11, the second exhaust pipe 21,
It further include sequentially connected first isolating valve 31, pneumatic operated valve 32, the second isolating valve 33,31 other end of the first isolating valve and first are taken out
Air pipe 11 connects, and 33 other end of the second isolating valve connect with the second exhaust pipe 21, and the first exhaust pipe 11 is respectively with first
Vacuum pump 12, the connection of the second vacuum pump 13, the second exhaust pipe 21 are connect with third vacuum pump 22, the 4th vacuum pump 23 respectively.
First exhaust pipe, 11 air inlet is connect with a condenser, and 21 air inlet of the second exhaust pipe is connect with another condenser.
Pneumatic operated valve 32 is solenoid diaphragm valve.
Condenser parallel connection vacuum evacuation device includes controller 34, further includes that the first pressure connecting respectively with controller 34 passes
Sensor 35 and second pressure sensor 36, first pressure sensor 35 are set in the first exhaust pipe 11, second pressure sensing
Device 36 is set in the second exhaust pipe 21；Controller 34 is connect with 32 control terminal of pneumatic operated valve.
Condenser parallel connection vacuum evacuation device further includes combined aural and visual alarm 37, and combined aural and visual alarm 37 is connect with controller 34.
MKS 722B13TCE is respectively adopted in first pressure sensor 35 and second pressure sensor 36.
Controller 34 uses Siemens S7-315PLC.37 model LTE_1101K of combined aural and visual alarm.
The device of above structure is in use, starting the first vacuum pump 12, third vacuum pump 22；It is true that second is enabled as needed
Sky pump 13 or the 4th vacuum pump 23；First pressure sensor 35 and second pressure sensor 36 detect the first exhaust pipe 11 respectively
With gas pressure in the second exhaust pipe 21；If first pressure sensor 35 detects 11 gas pressure of the first exhaust pipe
Greatly, second pressure sensor 36 detects that 21 gas pressure of the second exhaust pipe is small, then controller 34 sends control instruction, opens
Pneumatic operated valve 32；If first pressure sensor 35 detects the first exhaust pipe, 11 gas pressure is small, second pressure sensor 36
Detect that 21 gas pressure of the second exhaust pipe is big, then controller 34 sends control instruction, opens pneumatic operated valve 32；If the first pressure
It is big that force snesor 35 and second pressure sensor 36 are detected simultaneously by gas pressure, then controller 34 starts combined aural and visual alarm 37,
Related personnel is reminded to take measures；When unit maintenance, the first isolating valve 31 and the second isolating valve 33 are simultaneously closed off, avoids a machine
Another unit is had an impact when group maintenance.
