How to solve the low-pressure lockout issue in the hydrogen adsorption device?
Thread Content
For a three-stage parallel adsorption tower that operates in five stages – adsorption, backwashing, regeneration, cooling, and flushing – what should be done if the inlet valve locks due to low pressure? ?
Is it the excessive pressure difference? That one of yours isn’t an imported valve, right? It’s an outlet valve; that step is probably the cooling process for balancing pressure. Set all process valves to manual mode, close the purge hydrogen*4 valve, and open the valve for that column*4; then pressurize using electrolytic hydrogen. If the pressure is too high, simply open *5 to release pressure; of course, it’s still important to close *5 on the purging column – otherwise problems will arise. If the pressure difference is below 70 KPA, there is a simpler method: simply using that pressure difference value will have little impact.
