When the electrical conductivity in 5 outlet pipe 12 of flushing water recovered water pump is normal, (electrical conductivity is led higher than what boiler feedwater entered
Electric degree), Pneumatic butterfly valve e23 is closed, while optionally open Pneumatic butterfly valve g25 or Pneumatic butterfly valve i28.If waste water conveys at this time
Pump 6 then opens Pneumatic butterfly valve g25, flushing water then enters industrial wastewater by pipeline 16 and Pneumatic butterfly valve g25 in shutdown status
Pond 3；If waste water delivery pump 6 is in opening state at this time, Pneumatic butterfly valve i28 is opened, then flushing water then passes through liaison tube d
17 and Pneumatic butterfly valve i28, check-valves b29 enter the main water outlet pipe 13 of waste water delivery pump 6, and eventually enter into Industrial Wastewater Treatment dress
It puts, after the monitoring signals in electrical conductivity meter 31 return normally, closes Pneumatic butterfly valve g25 or Pneumatic butterfly valve i28, open pneumatic butterfly
Valve e23, system revert to normal operating condition.Pneumatic butterfly valve d22, Pneumatic butterfly valve f24, Pneumatic butterfly valve h26 are in control program
It is arranged to work at the same time.
When accident (boiler acid pickling and air preheater cleaning) occurs in unit, wastewater flow rate is larger at this time, if Industry Waste pond 3
When volume is difficult to meet needs, Pneumatic butterfly valve a19, Pneumatic butterfly valve b20 are opened at this time, and unit rhone waste water enters acidic and alkaline waste water
Pond 1 or flushing water recycling pond 2, when acidic and alkaline waste water pump 4 and the startup of flushing water recovered water pump 5, closing Pneumatic butterfly valve d22,
Pneumatic butterfly valve e23, Pneumatic butterfly valve f24, Pneumatic butterfly valve g25 open Pneumatic butterfly valve h26, Pneumatic butterfly valve i28, at this time acidic and alkaline waste water
The water outlet of pump 4 and flushing water recovered water pump 5 enters 6 main water outlet pipe 13 of waste water delivery pump, and eventually enters into Industrial Wastewater Treatment
Device.After accident elimination, Pneumatic butterfly valve a19, Pneumatic butterfly valve c21, Pneumatic butterfly valve h26, Pneumatic butterfly valve i28 are closed, opens gas
Dynamic butterfly valve d22 and Pneumatic butterfly valve e23, that is, can switch to normal operating condition of unit.
During operation the handover operation of valvular break-make and operating status can pass through transmissometer in control room and conduction
The detection signal remote control of degree without human attendance, realizes automation control.
