How should unqualified high-temperature and high-pressure condensate water be discharged on-site?
Thread Content
When the condensate contains excessive oil or iron ions, it needs to be discharged. The pressure in the pipeline system is 0.5 MPa and the temperature is over 150 degrees. According to the original design, when the water meets unacceptable standards, the solenoid valve leading to the purification device closes, while the pneumatic valve for discharge opens suddenly; this results in a very strong impact at the discharge point, which can damage the gutters and poses a serious risk. How can the exhaust outlet be handled safely without adding (modifying) equipment? I asked for advice! !
It’s necessary to reduce stress in such situations. If the amount of condensate water is high, it is advisable to install a drainage expansion tank to collect the wastewater in it; the flash vapor generated can be reused, while the wastewater remaining below can then be discharged
A pressure of 0.5 MPa is a bit high; it’s too dangerous to discharge the fluid directly without adding anything. Buffering fittings can be installed in the drainage well, but testing them first is essential to ensure safety.
May I ask, is the condensed water with excessive oil or iron ions discharged directly into the rainwater drainage ditch?
A pressure of 0.5 MPa is too low for steam; this is easy to address – the pipelines can be modified, and a buffer area or buffer tank can be designed. The key is to reduce the flow rate
