Principle of water seal in raw water tank
Thread Content
The water seal in the raw water tank at our factory has leaked. Please help analyze the cause and explain the principle of a water seal tank
The water seal tank contains a water seal at a certain high liquid level; if the pressure inside the tank is high, the gas inside will push through the water seal and be discharged through the exhaust pipe. Conversely, if there is a negative pressure inside the tank, the higher atmospheric pressure will force its way through the water seal into the tank, thereby keeping the raw material tank within a certain pressure range and ensuring safety.
Is this caused by a sudden significant increase in the amount of raw water supplied? ? We also faced this issue before; later, by coordinating the operations of various devices, we were able to stabilize the feed rate!
It is mainly caused by the high vapor phase of the incoming water. The issue needs to be identified by checking the outbound flow of acidic water from each device. To prevent safety accidents and environmental pollution.
The phenomenon you mentioned occurs because the pressure inside the storage tank is greater than the height of the water seal column. There are several main reasons for this: the pressure in the storage tank is too high； The water seal column is not high enough ； The pressure in the storage tank is rising too quickly (the breather valve is not functioning)
Check where the return water from your water seal tank is connected to, and where it goes If you explain this problem to me, I can clarify the principle and the solution for you!
