How to perform switching operations on a triple-lobe Roots blower
Thread Content
Our three-blade Roots blower is used for hydrogen treatment; the hydrogen passes through this blower before entering the hydrochloric acid synthesis furnace. If this three-blade Roots blower fails, how should we proceed with the switching operation? Thank you. Additionally, our Roots blower has a high outlet temperature; there is no cooler at the outlet, and the backflow temperature inside the unit is high. Therefore, a pipeline has been connected after the backflow control valve and leading to the front of the hydrogen scrubber tower.
It would be best to accompany this question with a flowchart, as it makes it easier to discuss. In fact, the operation of compressors is more or less the same. Preparation, startup, and switching while maintaining constant traffic. The key issue is the condition of the equipment during the period before it is connected to the grid and after the switchover – is it cyclic? Empty? I don’t know how to set it up. As for what you mentioned, “a line is connected after the backflow control valve leading to the front of the hydrogen scrubber”? Is it a cooler installed to lower the reflux temperature? And then back to the entrance in front of the machine? This explains it clearly; it should be a cooling tower, not a washing tower. It is better to send a schematic diagram.
It is not common to see Roots blowers used for transporting hydrogen. Pay attention, learn*. Looking forward to the follow-up.
