AI Technical Summary
Existing palladium membrane hydrogen purification devices suffer from problems such as uneven flow rate on the shell side, excessive hydrogen concentration gradient leading to membrane damage, surge in palladium consumption, high cost, increased energy consumption, and complex processes.
The palladium membrane hydrogen purification device adopts a flat-plate stacked design, which uses a gas distributor to achieve uniform gas distribution. The palladium membrane hydrogen purification plate is connected by bending to increase the contact area, and a stainless steel plate is used as the base plate support. Welding is used to improve the airtightness.
It improved hydrogen purification efficiency, reduced hydrogen concentration gradient, reduced palladium usage and cost, simplified process flow, and improved the gas tightness of the device.
