Selection of fans for intermittent air intake at the fan inlet
Thread Content
Our plant’s nitrogen generators produce oxygen-rich exhaust gas that we intend to recycle. We plan to use a fan to pump this gas directly outside, but the emission is intermittent, with the pressure difference fluctuating between 0 and 7.5 kilograms. Is there a fan suitable for such conditions? We do not want to use a buffer tank, considering space constraints and equipment costs. Could anyone help us solve this problem?
Your description is quite general. Factors such as your flow rate, pressure instability, whether it follows a pattern, the location where the gas is extracted, and the location to which the gas is delivered are all very important issues.
The flow rate is approximately 50 cubic meters per minute, with a discharge interval of 56 seconds
Such fans can be manufactured. Is there a pressure requirement for delivering air to the gas holder? If so, feel free to contact me; I can prepare a detailed plan for you
