What situations in the chemical process require the use of buffer tanks?
Thread Content
As title. In addition to the need to add a buffer tank to the gas compressed by the compressor, what other situations also need to add a buffer tank? Are there any criteria for judging this? Thanks!
Personally, I think it is generally necessary to add it, because this can make the pressure fluctuations change very little, which is beneficial to production and can protect the compressor.~
It mainly depends on whether the instantaneous system pressure changes greatly! !
Buffer tanks are widely used in boilers, water heaters, frequency conversion, and constant pressure water supply equipment. They buffer system pressure fluctuations, eliminate water hammer, and play the role of pressure stabilization and unloading. When the water pressure in the system changes slightly, the automatic expansion and contraction of the buffer tank air bag will have a certain buffering effect on changes in water pressure, ensuring that the water pressure of the system is stable, and the water pump will not be turned on frequently due to changes in pressure.
It acts as a buffer in places where instantaneous pressure changes are relatively large.
A buffer tank also generally needs to be installed in front of the vacuum pump to prevent back suction and stabilize the vacuum.
This is difficult to determine, and I have not seen relevant mandatory standards. I personally think it should be set according to the actual situation. For example, our hydrogen pipelines were previously equipped with buffer tanks to prevent the pressure in the pipeline from rapidly dropping when a large amount of hydrogen is suddenly used, which would affect normal use.
The vacuum pump station needs to add a buffer tank!
The explanations on the 4th and 6th floors are comprehensive. Learn from them.* Got it!
Mainly based on the two needs of ensuring safety and ensuring production. Ensure production needs: If you want to ensure that the system pressure is stable, you need to add a buffer tank ； Ensure safety needs: For example, add a buffer tank in front of the vacuum pump to prevent vacuum failure and back suction.
