Nitrogen sealing system
Thread Content
The situation on site is that the nitrogen inflow rate cannot keep up with the discharge rate; negative pressure occurs during discharging. Currently, the discharge flow rate is 32 t/h, while the nitrogen inflow rate is 38 cubic meters per hour.
Just increase the amount of nitrogen gas supplied. Do you have any questions?
It mainly depends on whether the instantaneous nitrogen supply during feeding is sufficient, not on the amount per hour. Otherwise, a vacuum is likely to form
How is the discharge volume calculated from tons per hour? If it can’t keep up, apply a bit more pressure with nitrogen; otherwise, increase the pipe diameter……
Can the vacuum generated by this discharge speed be equal to the nitrogen inlet speed? I just want to do some calculations to see if the nitrogen supply valve meets the requirements.
