How to filter out pressure fluctuations in the pipeline
Thread Content
During the filtration process, a filter aid needs to be added to the filter, and this is done at the inlet pipe of the filter, where the pipe is under pressure. A plunger pump is used for addition, and a considerable amount of filter aid is added as well; the plunger pump has significant power, which results in pressure fluctuations of 0.2–0.3 bar in the filter. Due to these fluctuations, the flow rate at the filter’s outlet also varies, with an error of around 0.1 ton. Such fluctuations have a significant impact on subsequent equipment. I would like to ask what methods can be used to eliminate these fluctuations?
Add a buffer tank at the outlet of the plunger pump
An accumulator can be installed at the pump outlet, which is quite useful for absorbing fluctuations
The plunger pump is very small; it can add only about 1 ton of liquid per hour, so the liquid is directly injected into the pipeline. There is a 2m3 buffer tank at the outlet of the filter. To prevent the CO2 gas in the medium from separating out, a pressure of 1 bar is required; however, with this pressure in place, the buffering effect seems poor, as the pressure causes fluctuations in flow rate
So it’s the energy storage device, right? When the outlet pressure fluctuates, is a reservoir used for buffering? Are there hygienic versions of accumulators?
Add a buffer tank at the outlet of the plunger pump; referring to the answer above, I’ve also learned that
