AI Technical Summary
During the deoxygenation process, the catalyst position inside the deoxygenation device remains fixed, resulting in insufficient reaction between hydrogen and catalyst, insufficient contact between oxygen in hydrogen and catalyst, reduced deoxygenation efficiency and effect, and insufficient purity of deoxygenated hydrogen.
The deoxygenation cylinder is installed using two symmetrically positioned support frames. A drive motor drives the rotating spindle and catalyst storage plate to rotate, causing the catalyst to flow in the catalyst storage plate and come into contact with hydrogen through the vent holes. Sealing strips and adjusting strips are used to seal the gap between the edge of the catalyst storage plate and the inner wall of the deoxygenation cylinder, ensuring that all hydrogen passes through the interior of the catalyst storage plate.
This improves the efficiency and effectiveness of hydrogen deoxygenation, ensures hydrogen purity, and ensures that the catalyst is in full contact with the oxygen in the hydrogen, preventing gas from passing through gaps and causing incomplete oxygen conversion, thus guaranteeing the purity of the hydrogen.
